How to fix a laptop killed by windows update - tutorial - Lenovo Legion 5 corrupt bios repair 

I always admired your fault finding abilities but it's nice to see you still developing your skills.

Always satisfying and a great learning experience to watch a true pro doing pro work. Well done (as always!), and thank you for sharing and teaching your knowledge... DT

Sorin you have delivered enough knowledge that the common user can express the exact problem leading to right direction.

It's nice that the machine is working again. However, it now has a different serial number or no serial number and the Windows key in the BIOS has been lost. With this BIOS it is easy to fix: Open the file in the Hex Editor, search for "LENV" and copy everything from the offset 75C000 to 75D250 into the working BIOS.

Your discord is the best there is for electronics Love to read the stories ❤

Awesome fix.

Good vid ,what is that screwdriver you using sounded powerful?

Thanks 🙏 god bless you and your family.

Checking out that Revelprog there. Curious what the adapter clamp is called you use to clamp onto the bios chip and how the Revelprog compares to the MiniPro or newer TL866II Plus Chip Tester. I like how it has the extra socket built in. My current programmer required an adapter for that which I had to wire up.

Thank you!

Only HP seems to consistently have a way to reflash the bios in case of failure, sometimes Dell I dont know why the rest of the industry doesnt grow up

love your channel sorin your not begger like some channels asking for money all time keep good work up

Its very common nowdays that the critical BIOS update is implemented by a Windows Update mechanism. Most of people still don't know that You have to update the BIOS to patch low level, critical security issue.

When flashing the bios in this manner, will the machine now have a different (or no) serial number, GUID, etc? (i.e. will it have the serial number of the laptop that the bios was dumped from, or possibly no serial number (and GUID, etc) if it was extracted from a BIOS update file??? Maybe this doesn't matter much?

Thanks 🙏

I had 2 Lenovo P51 laptops that were decommissioned because of corruption from BIOS update. Anyone interested in computer repair will need to learn the BIOS programming side of things these days, it seems..

My previous work laptop was Lenovo and current is Dell and both did the same thing. Had to hold button down to shut off power and reboot it. It seems to be a recurring issue for many laptop users and comes and goes with various updates.

Nice one

Thank you very much for sharing teacher. It was about time that luck smiled on us, that is, that at some point it was on our side. Let's hope she doesn't abandon us. All the best.

It is bad that Windows has started doing BIOS updates via it's Windows Updates. There has to be a way to disable this as it would eliminate these new software issues.

Ah, God damn bios issue 🤬 strikes again! Good job Sorin!

Hi Sorin. I need help. I have hp elitebook 8570p i7 laptop which have same symptoms like this one But i cant update bios via usb method (windows + b) which i saw in your previous video because official hp website have corrupt bios. I cant even open setup to make bootable. It says missing files. I have tried every prevoius version same issue. Even change pcs but no luck. Please help to find bios for me.

Hello good day , so I also have a legion 5 15ach6 and same issue and I strongly believe it’s also the bios , however I have a chip ready but it’s unable to read said chip at all, I really hope I can do the repair instead of having to ship it out

Hi! Where I get this BIOS, you have a link!

a screw fell on the motherboard and there was a burn, very small part burned. can it be repaired? the area is above ssd and near to wifi card in legion 5i pro

Basicly this is what i see on my lenovo y50-70...at begining we were thinking that there was missing 3.3v or super io is dead but laptop comes on and stays on without a screen...so i just have to reflash bios ;)

the world needs 'Secret Component' again

3:52 Dirty Harry Callahan: "Uh uh. I know what you're thinking, punk. You're thinking ``Did he fire six shots or only five?`` Now to tell you the truth, I've forgotten myself in all this excitement."

A friend asked me to take a look at his Lenovo Legion Y530. If I press the power button, the power button LED and power LED on the side light up for about 11 seconds, then both power off for another 11 seconds, and the cycle repeats itself until I hold the power button for 4 or 5 seconds. No image on the screen, no fans movement, nothing. Could it also be the BIOS? I tried unplugging the main battery and CMOS battery, then holding the power button for more than 60 seconds, but the problem still remains. It seems to charge OK, after a few hours the charging LED went from orange to white. Before charging it, the power button LED and side LED would blink for 11 seconds, then stop for 11 seconds.

Is a very nice work, I always feel happy when ever I watch ur videos but am gonna ask u a question please how do the call what u use in programming the bios.

As i started using Windows since Windows Xp, first thing to do was to block windows updates. Never used antivirus and never had any problems.

What's your discord channel url

It happened to me too once i think its something new in windows laptop automatically download bios update and do it on next restart... for me i had so bad luck i lost power in house for 1 second and exactly on that moment it happened :( so i needed to re flash bios manual with bios programmer. My suggestion to people is when they see something like that put charger into laptop and just leave it no mater how much time it take it will be ok.

What tool is that you used to read the bios? And does it have any other purposes other than bios chips

Yes ist true for intel i3 gen1

I have same problem with bios, can I fix it without opening laptop?

That looks almost like my issue my laptop died while I wasn’t home guess it was a windows update no clue but fans spin and gpu/cpu both heat up

Hello sir I have same issue but some times laptop work and when I shutdown it's make this issue . So it's bios issue or some thing else

Hi Sorin. Did you born in Sighisoara?

Hello, I have a bad laptop with the same bios/firmware issue. How can i get in contact with you to send you the laptop 15ACH6H

Could you please sir help me figure out what happened to my laptop? It is working but the inbuilt screen goes off when windows starts.

What if I replace Windows with Linux ? Mint f.i. Are Bios updates then no longer possible ? Thank you for this informative video 🤝🏻👍🏻🇳🇱

Hello, Please i need your support. My Lenovo Thinkpad P15v gen2 core i9 (21AA), not able to access bios and boots into OS (W10) after an update was performed. When Powered on it runs to a blank and black screen, it restarts every minutes less or more. Any attempt to enter the bios with the F's keys, the message pop up as following: Entering Setup. Entering asset information. Entering regulatory information. Entering Lenovo Diagnostics. Launching the recovery utility. Entering boot menu. Launching the setup interrupt menu. Etc. Please advise and advice. Regard

It's a bit off topic "Can un update kill your laptop", but can a simple RAM memory upgrade kill it to? Well. HP series 15 AMD Ryzen laptop: operation-new RAM module(unpack) upgrade, antistatic gloves on hands, fue screws etc. Turn on the laptop, no boot, just codes-error, after error. From M.2 SSD to "broken battery", below everything LT works slowly but good works. BIOS only sees the new module. Refreshing the BIOS because of the battery. I checked the SSD-dye.SSD and new OS installation are not a problem, but the clone battery-expensive lottery.There was no other. Updated BIOS, new SSD, win install. Battery back OK as before.But I still don't know what happened with the simple RAM upgrade(must takeoff cower)procedure. All the best Mr. Sorin

Hello, really like your stuff, my question is where can I find bios bin file for lenovo legion 5 15ARH05H, I have downloaded official bios update from lenovo but it is an .exe file. When I extract that there is no bin file. Do you know where I can get an bios bin file for lenovo legion 5 15ARH05H. Thank you and keep up the good work.

I have similar issues.

Thanks sori...i really need your help im looking for bios bin file for Dell latitude e5290 Ddm60 La-F391P rev 2.0 (A01) Help me plz 🙏

Once happened to me. Had to make sure I turn off windows updates for hardware everytime I get a new system. can't have microsoft corrupting my bios again

Tried updating my bios my screen went blank too. Lenovo V15-ADA: 82C7

The reader I have is the usb ch341

Sorin See you never in the shop working.. is there enough at your own online shop?

I have lenovo legion 5 15ach6h and it does not have any bios button where u show it in video , everything else is same , please help

An auto windows 11 crashed one of my laptops. I had auto updates off but one morning it said "welcome to windows 11" and when i went to log in it crashed and put me into windows reset but no reset options succeeded. each time crashing with a critical error. I took it to a local computer guy I know and he reset to windows 10 for me. I didn't have time to screw with it. "I could not get the laptop to the boot from usb window"

My y540-15irh keyboard was ruined by a firmware update. Is it so hard for Lenovo to just do nothing instead of killing our stuff?

I have the same problem I flashed the bios chip and not getting display

I noticed that windows update sometimes shows firmware updates. They are bios update. Don't do them! Every single time i tryed to do one with Hp laptops the update fully install, the pc reboot, fail to reboot, recover the old bios saved by itself somewhere and reflash it back. So AVOID windows firmware updates!

Idk, the discord server hasn't worked out good for me at all, never got any assistance, literally every time I post something there's always someone who post's right after with too many messages about things they could have said or included in 1 or 2 messages, my messages always gets drowned out by this

Mr Sorin please give us the answer about the previous video about charging capacitors position

Hi, can someone give me a hand? I have a Lenovo Y530 that had a working Nvidia gpu until I decided to change the thermal paste and didn't take away the battery. I dropped a screwdriver on the board, touched the gpu chip and the board and sparked, so I think it has shorted something or burned the GPU. The thing is that the board has nothing visible damaged and on the other hand the laptop is functioning like nothing happened. It is using the INTEL 630 and not reconizing the gpu on the device manager. What can I do to make sure that the chip is fully dead or if it is something else? Can the integrated graphic work if the nvidia chip is dead?

Windows update requires board removal? What the actual F Microsoft

its the "update" windows and flash bios! in this case, if your laptop shut down....you are screwed! never activate automatic bios updates!

Sorin I can see it in your face, you smiled like a kid who got the approval to play with his toy. 😁

Sorin.. update windows again the optional updates for firmware.

sure, bios update via windows

Thermal Grizzly kokonut 🤔🤔🤔🤔

Sorin, please send me an address to send something to you...please

External.screen test....

killed by Mi*ros*ft that detected as non genuine OS 😂

Grizzly is fine if u keep regularly changing, otherwise its waste as kryonaut get hard rock.

lol he/she reset while bios update. 🤣

Lenovos the absolute worst nowadays

i find it to be ridiculous how now-a-days the bios gets updated so often by the operating system. If there is a way to stop those updates, i think the smart thing would be to stop it from ever trying to update. There is no point to those updates.

Lenovo the worst BIOS' ever!

How in the hell an OS update can kill the bios?

My guess the customer interrupted the update when he rebooted. Probably a mistake.

Do you ever bump into your wife Sorin ? You seem to never stop working. Maybe she prefers it that way ?

when I see a lenovo laptop I directly assume it"s a bios issue, I had exp with lenovo, I didn even watch the whole video

Basically the new computers are bios problems by update timeline default .
