World's Easiest Laptop CPU Upgrade 

i miss those days when you could just swap and change the CPU, RAM, WLAN card, GPU and HDD😢😭

Hey, back in 2000s almost everything was upgradable. Most common thing I remember is big door on the bottom of laptop case that gave access to HDD, RAM, CPU, optical drive and expansion cards like wifi. Even more recent laptops have those - like Dell E7470 that I use as my main machine. LCD expansion function was very common on Pentim I/II machines (especially IBMs and Toshibas).

Laptops are probably one of the technological areas that have regressed the most in recent years when it comes to upgradeability and IO. My most recent laptop is from 2015 if I remember correctly. It isn't a particularly high-performance model or anything (it has a celeron for a processor), but despite that it still featured upgradeable ram, wlan, storage bay and a dvd drive. I've changed out my dvd drive for an additional hard drive in a caddy. I will however switch it back whenever I need to use some optical media. It's not hot-swappable, but it isn't a hassle either. Furthermore, it also had, what used to be, a normal amount of IO. Seriously, what's up with modern electronics and a severe lack of IO? Modern TVs are even worse. Are you supposed to just throw out all your old stuff or keep an old TV around? Or are you supposed to buy those signal converter boxes from brands you've never heard of, that are questionable at best?

The ThinkPad T440p is nearly as easy, 2 screws come off the bottom and then the cover slides off revealing just about everything (RAM, storage, CPU, optical drive, wireless card, etc), however you still have to loosen the screws and unplug the cooling assembly before you can replace the processor. I miss the upgradeability of these older laptops. Great video!

Nice one, was similarly surprised how upgradable my Inspiron 8100 was - the graphics card was also replacable, and it accepted the card and display panel from my somewhat broken Latitude C840. Went from a 1400x1050 display and Geforce2Go 16MB to a 1600x1200 display and GeForce 4 440 Go 64MB, and couple that with a 1.2GHz PIII-M upgrade, it's now an insane Windows 98/ME system! Only 4 screws and a somewhat annoying retention bar to upgrade the CPU, and a further 4 for the GPU.

for someone with 1.4k subs your videos are really well put together, hope your channel grows!

I had a Fujitsu Lifebook back in 2004, it had almost the same upgradability options aside from the CPU access which you need to tear down the laptop itself. but since it did not have Wifi Capability, back in the day, I purchased about 3 PCMCIA Express Expansion cards, 1 for Wifi, 1 for Bluetooth, and the other was a 4 Port USB 2.0 but what i loved the most about it is: 1. even when it just had a Pentium 4 M 3.0 HT, it out done the Desktop PC my family had at the time which was up to spec running Dual Core 3.0 CPU. 2. it had a small LCD screen with a few buttons mainly to be used as a Media Player control. with that said even if the LCD was closed, you had the capacity to play Music using the LCD and Player controls which was not covered by the LCD Screen and even see which was playing with that small screen.

My first AT&T 486 laptop had the 1.44 meg floppy no sound card, no modem and only ONE PCMCIA slot. So I could either use the sound expansion or my 14.4 fax modem expansion to dial into AOL. I could not WAIT to get a pentium 100 laptop with TWO PCMCIA slots.... Of course laptops started coming with modems and sound cards built right in and I no longer needed the expansion slots. Though there is still one computer at work that needs the slot for a dedicated PLC communication. Oh how our tech changes! Great review!

yesterday i was literally disasembeling that exact laptop for a school project and noticed now easy it was to upgrade

It's funny that I literally just did this on my B130 and filmed it as well before I ever even saw your video, which popped up on my feed as I was editing the video I shot of upgrading the laptop!

I was a field warranty tech for Dell back in 2006 and I worked on a few B130's. The Celeron M is why the CPU can be located where it is with that tiny heatsink. Pentium M wouldn't be an issue either, but Celeron M was all that was offered on those. The B130 even mimics the appearance of the Dx20/Dx30 latitudes. It was a basic laptop for schools really, a few businesses had them when they didn't need a ton of power. Even though the Dx20 and Dx30 series didn't have the CPU under a cover like that, they were still VERY easy to disassemble. I disassembled a D820 Latitude so fast once (Motherboard replacement) the customer came back in the conference room as I was finishing up thinking I had only just begun. I think my best time on a D820 was 15 minutes from start to reassembled, without power tools.

I actually scrapped one of these recently; the doors on the underside were all missing or broken so reusing it wouldn't have been realistic. I was thoroughly impressed by the build quality though. I think the hinges were actually just incredibly solid; mine had had a lot of use and they still felt amazing. The only complaint I would have levelled at it was that it didn't use the standard Dell charging port.

I've kept my 2010 Dell Precision M4500 pretty up to date due to expansion. I still use it, it's been on and running almost every single day since I got it.

I bought my Lenovo Thinkpad T420 in 2013 and it has doors on the bottom to upgrade Cd/RAM/Wifi and it has Express ports, You can change the CPU but you have to open up the case to do it which is not hard. So you can change an i5 for an i7. What I miss most about old laptops is removing the battery

ACER (back on the CELERON era) used one big cover that you can take off givving access to all memory wifi and CPU. The opening is big enough to take cooler and heatpipe .... which is good since allows more in depth cleaning

I am probably one of 5 people that never ran into any problems with Vista. not a single issue with the 5 -7 machines I had it installed on.

They really don't make em like they used to... My almost 10 year old Thinkpad T440P to this day still gets me through a lot of work. Never letting go of that beast. Trying to find an i7 4700MQ to swap out the stock i5. Literally everything else in my laptop has been swapped out lol. Really hope we'll get laptops like this again someday. Great video dude!

You can use the Express card slot to add 3 USB3 jacks, I did it on my Dell XPS M1730 and it works well.

My old Asus laptop from 2010 it can upgrade almost everything like cpu ram hdd ssd and even delicate gpu because it use mxm interface

when the laptops was literally portable desktops...

What’s nice is that almost every Inspiron from this era up until the 2010’s was super easy to upgrade. You had to take em apart most of the time, but I’ve turbo charged so many dell laptops by upgrading their CPU’s, ram, and replacing their hard drives with SSD’s. They honestly are quite easy to turbo charge.

2:37 The engineer responsible for this was probably looked at with contempt by sales people.

I have a 2013 Dell Precision M6700, the socketed CPU and GPU cards are upgradable, it also has multiple storage bays for expansion. I am using it as a daily device at work and running Win 10. The Quadro K5000m is still doing a decent job for everything but modern video production encoding/decoding. I personally replaced the 3rd gen dual core I7 for the 4-core version.

The PCMCIA slots were for memory cards or air cards (cellular modems) to allow you to connect to the internet on the road. My internal modem crapped out so I wound up buying a PCMCIA modem card. Those were quite the thing in the late '90s and early 2000s.

When the manufacturers focus on delivering quality & robustness instead of planned obsolescence.

I still have the same model and it still works, although I did not know that I could upgrade the cpu. I'll definitely upgrade the cpu, it seems like a cool project

I have a big notebook that has the same kind of cooler design. But it supports Desktop Pentium 4 CPUs. Pretty interesting to see that inside a notebook.

Benefits with optical drive is, that, it's possible to add extra storage like 2nd hard drive.

Thanks for video playback support .

In the past laptops were designed by engineers, later marketologists appeared.

I'd be curious to see you try some different ram modules in there to see if you could improve the speed, or at least see some improved timings and if there is a measurable difference.

Laptops were so upgradable back then, I miss the old days.

This would kind of come in handy with gaming laptops with them giving us the max on how fast a CPU should be and if we can swap it out for Intel or AMD. I know that the GPU would still be built in "since some manufactures had tried that in the past with upgradability" but, regardless it would at least be nice to get an option just like that

Business class laptops are a joy to upgrade. For all others, I've always been able to find a disassembly video right here on RU-vid!

and even on some laptops you can replace the gpu in laptops that use the MXM connector (Mobile PCI Express Module) a bit rare nowadays. also some were limited because of PC's biso proprietary junk that the OEMs used and on older dells they used i don't know what it called it was some kind of mini AGP or some other proprietary connector.

Celeron M also doesn't have Speedstep fonctionnality. Another laptop easy to Upgrade is the Acer Extensa 4000 series (or aspire 1690) only 5screws to change the cpu.

If you are interested in modular, upgradeable and serviceable laptops you may have heard of the Framework laptop. If you haven't - be sure to check them out as you can upgrade/replace/customize pretty much every part of it individually with the added benefit of the laptop actually being thin and light.

A newer style ish laptop that I used to own, allowed me to upgrade pretty much everything, by removeing one screw, then you released the bottom cover with the battery latch. HP Probook 4440s, I upgraded mine from a sandy bridge celeron, to an ivybridge i5! That thing was my daily school laptop for 3 years! I want to buy it again.

the problem you mention regarding the speed of the FSB is not due to the processor it works at the declared frequency, it is the DDR rams that work from 266 to 400 mghz, the DDR2 go from 533 to 800 etc, so the only speed limit is due only to the components supported by the device which is in this case the type of RAM supported. cpu z similar software also detect real values ​​as there is no need to make invasive changes (in some cases harmful) of the BIOS firmware As in CPU Spec its says exactli that M version support only 400 mghz FSB The revisited version ( Centrino ) support fastests RAMs like DDR2 533 mghz up

My two laptops, the older one, an Acer Extensa 5220, and the newer one, always Acer, but a gaming rig, the Nitro 5 year 2020, are an exception to the modern rule. The first, predictably since it's a legacy, I upgraded the hell out of with a new dual core CPU (a core duo T7700, I think it was, been a while, the fastest CPU supported) and 3Gb of RAM (max memory amount supported by the mobo) and an SSD. Its hinger are so stiff too, you need two hands to open it, to say. The second, though I had to open it whole (thing easy enough to do for me) since sadly it lacks fast access hatches like the majority of new laptops out there (though it seems the 2018 one still had them), I brought it to 32GB RAM and added a card SSD... only to discover a little too late it could accomodate another M1 SSD (that next year I will add too), to say it is written near the keyboard it could. It's official, I'm an idiot. So, I guess it depends on what laptop we're talking about. Muscle-bound gaming rigs still can to a degree (though I don't think my Nitro 5 can have a CPU upgrade, it's already an i7 10th gen, so it's not so bad) while super-thin ones... well, I guess it depends. Some still can accept memory and HD upgrade, though you must completely open them to do it, and others just sacrifice possibility of upgrade upon the altar of portability or builder choice.

You could also install a light weight LINUX distro and have that sucker flying again (maybe even faster than when it was originally released) - and totally up-to-date.

I saw your laptop service tag number, and I'm gonna steal it :D

My old toshiba upgrade from i5 to i7, ssd drive and 16gb. Still runs solid. And its already 10 years old

there was also Asus M50V that had easily upgradeable GPU. The CPU was upgradeable (albeit you had to remove a bit more) also on much newer 2009 Vostro 1510 laptops that you can find with a nVidia 8000 series GPU if you are truly lucky. Pretty competent setup for the time and great for winXP laptop gaming. I bought mine from the school I studied at and man, it is my baby. It received the best CPU the chipset can handle (Core 2 Duo T9500) and 4GB of DDR2 RAM with a 256GB SSD. I love it. And since I was the one using it it also holds personal value. It can't do Crysis but it can do Oblivion/Fallout New Vegas. And that is the peak I want from it.

god I miss those days, Most companies were like this, I worked on a bunch of brands from the early 2000's that all had easy access to every component

@NTG Technology Are you still looking for a case for the windows xp rig ? Could be worth keeping a lookout after the " nexus prominent 9 " orignially released around 2011. It's a bit heavy case at just around 9 kg but i still use it since i bought it cheap in 2014. Using it without one of the sidepanels on due too the tight space it's sitting in the cubby is almost like a sidepanel anyway while restricting top airflow a bit as well. But should be more then enough cooling for a Core 2 Extreme & SLI 8800 GTX's being made in the era of the GTX 480 & GTX 590. Current setup of my main pc is that case housing a I5 2500k @ 4.4 ghz, 16 gb ram @ 1600 mhz via 4x4 configuration & gtx 1660 super that I've had for a bit less then 2 years. Gonna be 2 years around October 4th or 6th i think is when i picked the 1660 super up. Got it at a bargain 2335 sek or 223$ as an open box return like a week or two before prices skyrocketed on graphics cards, glad i went for that honestly. Or i would have been stuck with my old hd 6870 or hd 5770. It was returned because of the shuddering noise on the fans going from passive too actively cooled on the fan profile, thats the only thing wrong & its likely gone now because I've kept using the card. Literally a 5 minute fix making my own fan profile & 0 issues with the card outside of old game compatibility messing up with the higher vram limit at 6 gb but eh i got other pcs i can play those games on if Dgvoodoo2 or Nglide doesn't help fixing those issues besides community patches, talking like 20+ year old games here like Need For Speed Porsche 2000. For windows xp i got a Dell Inspiron 6000 laptop here released around mid 2005. So 2.5 ide hdd unfortunately on this particular model but a dedicated ati x300 gpu using ram as vram, 2 gb ddr2 ram 533 mhz sticks that runs at 400 mhz just fine. Using a 90w charger the laptop complains about & limits cpu power too 600 mhz normally. But i can get around that with crystalcpuid forcing the cpu too 1.5 ghz again while slightly undervolting the cpu as well. Pentium m @ 1.5 ghz which depending on what i play on here is more then enough for the built in 1280x800 display. HDD was replaced not too long ago with a 60 gb from a dead apple g4 powerbook i think it was. That powerbook has been junked for like 3 years by now after i tore it down, was some late spec model a year or two before apple went with intel core 2 duo's, cpu was a powerpc 667 mhz, 2x 128 mb ram sticks for 256 mb & the optional 60 gb hdd.

Hey I wanna do a pinmod on this notebook. Is it true that if I short pin 15 and 16 in third row it will overclock my Celeron m from 1.5ghz to 2.0ghz ?

I have one it’s not working any tips in what I should do to it please

Dell Inspiron 1420 has this exact same CPU upgrade convinience - but if you wanna clean and lubricate the fan, that's a mobo removal. Others have one big panel combining all of these compartments together, like on XPS M1330, Vostro 1510/1520, Latitude E series. Kinda odd I know on Latitude D620/D630/D820/D830 the cpu upgrade is unnecessarily difficult to get to.

nice! i have an ipsiron 6400, discreteradeon gpu and an upgraded core 2 duo @ 2.3 GHz(i think), upgraded to 4G ram ddr2/800, yes its slow with windows 10, but great for a linux box. screen is beautiful 15" great keyboard, great speakers and yes, the hinge works beatufully still

I had a sony vaio with these easy access to ram and HDD/SDD, it was amazing in that regard.

That was my first laptop. Bought it with a 512MB memory and a 1.7Ghz celeron. Over the years I had to take it apart and fix it several times. Along the way I upgraded the RAM to 2GB and a 2Ghz Pentium for cheap years later. It also didn't have a camera or microphone. The hinges on it are a little loose but still hold up.

I suggest you get some plastic blade decal scrapers for removing old paste in the future.

I got an old toshiba laptop from vista era, put an ssd, installed bodhi linux and it works great. Dual core intel cpu, 3 gigs ram, the screen is a bit s*it 15" tft panel. it was incredibly laggy when I first started it, and as soon as I removed the depleted battery it worked like a charm. The chip in the battery was somehow halting the whole system, later I scooped the cells out and put in the empty shell because one of the rubber legs was on the battery. It's a great laptop for dosbox and exploring linux OS, I only wish it had a better IPS screen, maybe I'll replace it, I've seen it can be done. It's a pretty sturdy laptop, built like a tank unlike these modern laptops. I need to replace cmos battery, and for that I have to disassemble the whole thing, and it's a weld on battery unfortunately, but I can live without the battery for now.

Amazing, I have a costumer that bring me this laptop today. Beautiful dinosaur from 2006 working as the first day. I'm going to put an SSD inside with 2gb ram to see how the computer works. Beatiful video, beautiful dell, beautiful everything!

I think the cpu socket is available on laptop until the m series intel gen4 with intel hd4600, right?

I think upgradability has been compromised with thinning out the laptops.

My father's laptop from 2012 had an amd cpu that you could also remove I once deep cleaned everything and accidentally bend one of the pins, though I was able to get it right again What was surprising to me is, those CPUs weigh nearly nothing and the pins are really really hard. Like, it can bend a pin if you drop, but actually trying to bend it back was quite the task.

The slightly obscure Clevo D47EV is this simple as well. You pop a door off and unscrew the cooler. Under that you find a standard socketed desktop Pentium 4 CPU of all things!

I had a B130 just like this one, but with the Pentium M 1.7 Ghz with 1gb ram and it came with Windows Vista Basic, as it could not run Windows Aero. Great computer!

I have an early Latitude and still use it for basic word processing, the screen hinge can be tighten ed I realised whilst adding a new battery. I wish I could upgrade that to 16gb ram or higher, i7 level chip would be so cool. I have a spare 500gb ssd about.

You should upgrade a Sony Vaio VGN-FW560F. They have upgradeable ram, CPU, Drive, and various accessories that are cool. I'd love to see one with a proper CPU upgrade tutorial. And no it's not too easy to disassemble but a powerful little thing when set up with drivers and proper windows.

Express card was awesome. It was a PCI Express slot that you could plug basically anything into. You could add USB 3.0 ports, eSATA, Firewire ports (yes Firewire was better than USB 2.0). You could add PCIe Gigabit Ethernet if the system only had 100Mb. Think of Express card as a early Thunderbolt system. If Expresscard still existed today you could plug an eGPU into it

That's a lot of fun and thank for share

Wow, crazy seeing a laptop being so serviceable. Not sure if the trade off for super thin compact laptops is worth it honestly.

i have the same laptop. upgraded it from a 1.4 GHz celeron M to a 2.13 GHz pentium M.

are there any models of dell latitude can change cpus easy like this one? ps: i would prefer to install Windows 2000 on it the screen resolution can be 1024x768

12:08 "and just blew away all this back in my room ,thats..... good work" hahahahahahha i was crying of laugh :D

I have a 2 GHz Pentium M laptop with 2 2 GB RAM and 128 GB SSD. I run Q4OS with the Trinity desktop. There are command line utilities for RU-vid and Spotify.

USB 4 and thunderbolt have the same idea, just implemented in a worse way. expresscard has PCI, those have PCIe it's a newer version of the same thing essentially. EC used to be the fastest way to transfer data out of the PC

I have (Intel pentium n3700) 1.60ghz 4cores and 4threars) Codename: Brasswell Package: Socket 1170 BGA what js supported here?

Man, I miss these kinds of laptops

I have a ECS/Uniwill L51** series laptop (this one is GQ/Frys!) that is waiting for the Core Duo T2500 and Intel 3945abg card to arrive to bring to Centrino specs. Everything except 1 memory slot under keyboard is easily accessable under 1 cover.

My 2012~13 Latitude is quite similar, 5 screws and you open the hole bottom, RAM, HDD, CPU, and evan 3 mSATA, 2 of wich actually are mPCIe. Quite upgradable and powerful, full of slots, just take a look on the specs and you gonna be surprised, Latitude E6430

How far can you upgrade one of this Laptops ?

The Sager NP8180 with a 2960xm and dual 6990ms was super super easy to upgrade literally 3 screws to reach all the parts and 4 screws for each part and you are done. A repaste takes exactly 5 mins for the 2 GPUs and CPU

I've got a 2020 HP 250 G7 (pretty thick), but I like it and you can swap out the RAM and SSD. I upgraded from 8G to 16G RAM.

I wanted to add a new Intel CPU to my Asus H97M-e mainboard that has an old Intel i5 4460 CPU but in the computer shop they said that all Intel CPUs have different sockets and a new CPU won't fit on my mainboard.

I had this laptop and used to play a lot of Doom 3 and CS Source on it back in the day. The best part about the cpu socket is you can do a mod to overclock your existing CPU. I put a little piece of wire in between the two pins and my 1.5ghz celeron M became a 2ghz pentium for free. Too bad the laptop got stolen though. I still miss it.

i have that exact same laptop still works as good as ever

Great little showcase (I'm sad now too)

I have a laptop with a socketed 64 bit AMD CPU the only thing is there are not a whole lot of worthwhile upgrades for it. That and it would take a fair bit of disassembly to get to it since it is not on the easily accessible side.

My Asus A3H is just as nice for the same reasons. The current Pentium M770 crushes the original Celeron M380, and in fact is nearly as fast as a P4 HT 3.2GHz (and the Celeron M doesn't have speedstep and less cache if I remember correctly - the FSB speed is lowered to change the clock speed instead). USB 3.0 works well over the expresscard slot as well.

RU-vid really got bloated over the years, I remember being able to play 720p without any frame drops in 2010-11 when I stopped using my old Toshiba Satellite with similar Celeron, and moreso I remember playing 240p RU-vid on Pentium II 400MHz laptop around 2009 and it worked pretty well.

at 4:12 those hinges and keyboards on old laptops like the dell in this video are robust! I have a 3 year old msi laptop and while closing the lid the hinge broke and damaged part of the screen + peeled part of the bezel away from the screen. My wife bought a new laptop and the hinge broke in the 1st week but it was under warranty so she just exchanged it for a new one. I guess my point is the older laptops were made stronger and built to travel and all these new laptops seem fragile.

I have a Toshiba L70 satellite PRO, which must be close to 10 years old. Still runs great with Windows 10 with an SSD.

Mainly due to the shift to lightweight models and portability

why did you take the foil off? it has better thermal conductivity than thermal paste.

Yeah when I opened my laptop years back and realized it was literally a socket, I was kind of annoyed that I bought the 2nd fastest chip on the platform. I could’ve bought the i3 version for cheaper and then bought the i7 extreme or whatever it is. It’s crazy how powerful the top end mobile CPUs used to be. My 4800mq is still barely slower than my modern ryzen chip. I used to be able to overclock on my laptop, but after updating it one day that functionality went away and I wasn’t able to revert back to previous settings. Idk why I can’t fix this, but back when I could overclock, sure it was hot, but I could set it at 4ghz and it was basically just as fast as a ryzen 2000 or a 7th-8th gen Intel chip. The speed of this cheap cpu is so astounding that I’ve actually been looking for an industrial or diagnostic motherboard that I could plop it into and use outside of a laptop. With good cooling this thing would be a monster. Paired with a decent gpu, it would be an incredible gaming pc. The Radeon graphics leave much to be desired.

Clevo and Sager laptops still use desktop CPU's and feature unlocked bios and GPU cards that can all be upgraded.

I remember people buying laptop cpu's for their desktop as some of them were really good for overclocking.

Compal PBL00(DNS Travel). Very easy to maintain, also manage and every component held by one screw:) You can upgrade them from Pentium/Celeron to i5 2540m or even i7 2620m(but it doesn't make sense to buy i7 one)

Well, regarding upgradability - some things make sense nowadays, while others don't (whatever Apple's doing never makes sense from the consumer standpoint, though). Soldered components can be faster (imagine having soldered LPDDRX ram right next to your cpu instead of having SODIMM slots that are far - traces-wise) and more energy efficient, and their small footprint allows for smaller and lighter devices - unlike the laptop you're working on. Replaceable batteries, MXM slot, upgradeable wifi and storage are great. But I'd rather have soldered cpu and ram and better non-upgraeable cooling, because that tiny copper cpu cooler wouldn't do nothing when paired with a modern cpu. Tech back then wasn't as demanding (and really far back there were no standards and companies did whatever they felt like is right), while nowadays the chips are so dense that doing it 'the old way' isn't practical. Companies like EUROCOM still offer 'upgradeable' laptops if that's really your thing, but I wouldn't call those LAPtops - more like dekstop replacements.

Contact cleaner can de-solve thermal paste. Also, the largest DDR2 sticks I've seen are 2GB, so if this has 2 ram slots, you should be able to bump it up

The Dell Inspiron 1545 is very similar and super easy to upgrade the CPU and other components.

Put an ssd on it it will boost the performance much mostly on such low system, also remove the DVD roon, and install a second like an optane disk used to boost startup and paging

I have a Sony Vaio from 2013 that had a pentium dualcore cpu (socketed) replaced it with an i5 cpu. Works like charm and it performs much much better. I also have an old Lenovo Thinkpad R61 which has a socketed cpu (dual core at 2ghz). I don't know if a quadcore works in this machine at all. Managed to upgrade my R61 to 8gb of ddr2 800mhz. 4gb ddr2 laptop ram-modules aren't easy to find.

Everyone be talking 'bout framework n stuff but this dude right here is more upgradable and easier to maintain than any computer ever coming out ma guy. Linus' investment is endangered by this.

Ohh neato I saw the title and now I want to see this

my thinkpad t470 i got refurbished for $350 with the bios firmware update i can use windows 11 and also it can upgrade nvme disk, and memory and wifi , but cpu on the board stilll good for a more newer laptop.... i bought a 8gb stick and a 500gb nvme to replace a 256gb nvme and add 8 more gb to make 16gb with windows 11 i got a very good laptop for about $500 total and this thinkpad keyboard is amazing
