Dell Inspiron 1545 | Motherboard Replacement | How-To-Tutorial 

Just wanted to drop a note that this was an excellent step by step! Fantastic video. Removed this motherboard from my laptop in 15 minutes. Would of been 15 hours without this video. Everything was there and exactly as you showed. Waiting on the replacement. Awesome that there's reassembly in second half. Brilliant!! Thank you for this!! :)

The thermal pads and thermal compound make contact with the CPU, GPU, and heatsink to transfer heat and keep the laptop running cool. If the pads or compound it not there, it would make the laptop hot and keep the fan running at high speed.

You can check the part number for the motherboard, there should be a sticker that says DP/N: 0h413n somewhere on the motherboard. Or if you install the motherboard Device Manager should say the video is ATI Radeon ™4330 (Discrete). To be clear, you are aware that the 1545 only has on-board GPUs. It doesn't have an option for a separate video card.

There are two different GPU options for that system. One is the Integrated Intel Video and the other is the Discrete ATI Radeon 4330 Video.

No, there is only one intel motherboard for the 1545 and it uses the M274K heatsink. You could change the motherboard to the ATI version but you would have to change the heatsink to a K364N. There are 2 ATI motherboard part numbers, 937GW and H314N. Both of the boards have the same performance just different part numbers.

Google "thermal compound". It ranges from $8-$15. It goes on the CPU and GPU contact surfaces. Not the fan.

Great job! Clear and thorough procedure. These guys didn't miss a beat! You can follow this video with confidence.

Oh yeah I see that makes allot of sense thanks for that I had no idea the heat sink was for the GPU as well thanks for your help friend :)

1. Core Duo or Core 2 Duo 2. 1mb, 2mb, or 3mb cache 3. 667mhz, 800Mhz, or 1067Mhz bus speed If the processor meets the criteria then it will be compatible. There are several processor out there, you will have to find one with the best speed. All of the i-series (i3,i5,i7) are not compatible. Keep in mind, the GPU is built onto the motherboard, isn't upgradable, and tends to overheat easily. I've heard about problems with game play on this system because of that.

Thank you so much for taking the time to create this video; it really helped me change my 1545 motherboard.

No, the 1545 will only use Celeron or core 2 duo processors. The CPUs must meet these criteria: 1. Core Duo or Core 2 Duo 2. 1mb, 2mb, or 3mb cache 3. 667mhz, 800Mhz, or 1067Mhz bus speed There are more details in the other comments.

Perfect. Just what I needed - many thanks.

Its because the heatsink isn't covering the GPU so the laptop is overheating. I wouldn't suggest running the laptop without the proper heatsink, you could fry the motherboard.

According to Dell's specs, no, but it is a core 2 duo so it may work. I haven't tried it myself.

No, the 1545 and the N7010 are really different. You may be able to find the disassembly manual for the N7010 at support(dot)dell(dot)com. Unfortunately I haven't obtained one to make videos yet.

Thanks man u helped Me a lot and you definatly deserved a like

Yes, but you wold have to replace the CPU, heatsink, and fan too.

The CPU and memory would be able to change over but you would need to get the correct heatsink for the ATI motherboard.

Dell's internal spec sheet shows the "compatible" CPUs and the T9600 isn't one of them. I'm not sure if it's because the CPU was introduced after the laptop was made or if there is something else that make it incompatible. The CPU specs appear to be compatible so it might work. I haven't tried it myself so, I'm not certain.

Yes, the LCD cable lifts straight up away from the motherboard.

one word, Profesional !

I'm not sure if replacing the fan will fix it, I haven't come across that problem before. We sell the fans for $25. First, did you make sure to replace the thermal pads and or thermal compound on the heatsink? If you didn't, that could cause the fan to kick on to high speed.

This is amazing and saved me a ton of money! Thank you so much!! :)

Thank you so much for making this video.

Thanks friend.

There is a link to written instructions above

Thanks for sharing

I would probably go with the Discrete ATI Radeon 4330 Video for better performance.

Unfortunately I do not believe so and it is due to the fact that the GPU chip set is integrated on to the motherboard and can not be changed.

It maybe because the T9600 has a 6mb cache and specs show it can use up to a 3mb cache.

Thanks! Great tutorial

Yeah I am it's only choice is the ati radeon intergrated into the mother biard or the origional mother board which has an intel 4 series graphics card. Also it was a mistake in the guy that sold me its part because it is a 845F or whatever just like my old one so I had to order a new one and this time it is definitely the h435n and I've got the new heat sink on order too :)

great vid perfect

That's odd. Have you tried re-seating the fan cable?

Ok, thanks! If I will ever buy the T9600, i'll post in the comment, if it worked out :)

Yes i just tried again, still having the same problem? if I want to change the fan will it fix it ? and how much would it cost?

I haven't had the new heat sink delivered yet though do I think it might be the fans too slow???? What would you say, because the old heat sinks aluminium sits on the CPU fine!

Right I have the new mother board and the new heat sink bought directly from your website ;). But it's still overheating after like 10 mins or so and shuts itself down?!

Right I just put in the new 413 mother board and it keeps on cutting out when It starts up windows everything is in place the CPU the memory the spaghetti everything is where it should be but it just will not make it past the bios part

Hey Friend awesome Video very helpful ... o yeah i am confused about if u upgrade that motherboard can you able to upgrade cpu to intel i7 ?? Plz Respond !

Thanks I need this my computer same as the one in the video locked up on me in safe mode and would not accept my Admin PW so this is the first for me disassembly to lift out the battery I believe this will reset the Bios which also cause me an issue with PW the default was not functioning this video may help me....thanks..

is perfect :)

Great tutorial.!! My motherboard is 0CJFHX, I can change for 0H314N? it is necessary to know the service tag of the new motherboard for modify it in the BIOS Both motherboards accept DDR3 RAM.? Thanks!

What's the issue with it not supposed to work with this computer?

I Fixed the display now, but now after i turn it on the fan goes faster and faster each sec then shuts down! please help

I am replacing power connector on this model. Can I get a replacement receptacle or do I need the whole daughter board? And if so any ideas on where to obtain same.

At 3:12 you disconnect the LCD cable, how exactly did you do this? Did you pull it upwards or towards the screen? I don't want to break mine, thanks

hear that type of battery used bios dell inspiron 1545 on plate

Hi! Can I use a Intel Core 2 Duo T9600 processor with this computer (right now, I have a T6500)?

thank you so mush .but my cam not work idon't know what i do for that

gracias me sirvio facil

Okay it's finnalt stopped over heating and it works fine but now I can't get the drivers to work on the ati radeon 4330 I have installed the right ones and that the 64bit vista one but it still just says standard VGA adapter under device manager

Thanks 4 replying, Im sorry but i dont know whats a thermal pads or thermal compound on the heatsink? could u explain please? :D thanks

What is the name of motherboard dell inspiron 1545?

Hello :D i did a mother removal to remove the CMOS battery for BIOS password reset, after turning it on my fan spins then stops without booting anything (blank screen) please help

Thanks

Will this work for a Dell Inspiron N7010?

How do you unhook the lvds video cable under the keyboard? You skiffed right over it and time lapsed it.

Okay so I got the new mother board on eBay the 413n and apparently it comes with an ati radeon 4330 but it fitted it and it still has an onboard 4 series heap of junk on it!!! So I only got the board itself either the guy lied and actually it isent a 413n or the part with the ati radeon on he didn't give me? Any help greatly appreciated many thanks :(

Thanks 4 explaining, I believe its like a white liquid that u put on the cpu and the gpu ? or under CPU Fans in a PC? How much would it cost me to get one? :) Thanks a lot 4 ur help

Hey dude thanks for your videos :) may I ask if I was to straight swap out the intel mother board and put in the one with the ati radeon HD 4330 First off I would have to move my duo core prossesor CPU chip over, would that be simple and would it work? Also is that all id have to do? Also what would I do about the RAM as I belive the ati radeon motherboard is ddr3 and my ram is ddr2 :S please help many thanks

Hey, it is very nice video. I am writing to get some suggestions that I am having with my same model laptop..I have a weird startup problem with my same model laptop Dell Inspiring1545. I was googling it from long time and could not figure out any solution from anybody. My laptop turns on only once in week.For example, If I turn on Sunday it will run continuously without any problem, but if I shutdown either way by home button or power card pulling it won't boot to windows. It shows the dell logo after that it goes to black screen with blinking cursor and stops there. I tried multiple options like swapping and cleaning the RAMs, pressing F12 or F2 continuously. None of them worked. Only thing I have to do is wait approximately a week to get booted normally. I have also tried dell support assistant but it did not get install , because it is a windows Vista. It asks me to get windows 7 first. Even I tried to install windows 7 it did not go to BIOS and stops at dark screen with blinking white cursor. I could not understand the problem. Seems you are good expert and want to know if you have any suggestions. It will be a great help and I really appreciate it.

What is the correct heat sink :) and for that matter what is a heat sink lol thanks much for replying

Thnx m8

Thanks for the video, but I did it all and now when I cut the computer on it just beeps. Its 2 beeps then pauses and 2 again. wITH BLACK SCREEN but I can hear the fan running. Whats the problem here u think?

Hey I have a question I'm hoping you or someone can answer. I followed this procedure to replace the charger board on my Inspiron 1545 because it wasn't charging the battery. (That's the little piggy-back board on the left side that has the charger port, VGA port, and a couple USB ports on it). Prior to replacing that board, the laptop would run plugged in, but just wouldn't charge. After replacing it with a new board, it won't boot up at all. When I press the power button, the fan runs for a couple seconds and stops and the video display remains dark. However the power indicator light stays lit until I press the power button again to turn it off. So I took it back apart and put the original charger board back in, but still no good. So I then thought either the new charger board damaged the motherboard or I damaged it flexing it to remove. So I bought and installed a new mother board (and used the old original charger board in case that's what killed it) With a new motherboard, it still does the same thing as above and won't come on completely. I also turned it on with the memory removed and got the 2-beep bios error so I assume the CPU is working. I also tried it with the hard drive and optical drive, and wireless card removed to eliminate them as a cause of the problem. I have no idea what I might have done that killed it. I would really appreciate any advice or suggestions. Thanks!

Don't worry dude just read the post bellow k364n ;) thanks

Okay dont worry I finnalt found it :)

can i change the graphics card

i have an inspiron 1501 that has only powered up twice since ive owned it. i think there is an issue with the computer and its connectors and what i wanted to do was create an external charger for my batteries for this computer but the issue is i dont have schematics and i've had some time trying to find them. i need to know the purpose of each of the 9 connectors on the battery, like whats the ground, power, etc etc.

I dont have the money for an external charger and im willing to experiment on the computer but i just cant get the info for those small connectors on this battery. i figure someone here would know and me and my friend are fully aware of the risks and no how to monitor the battery safely since we work on electronics alot. if anyone could help it would be appreciated.
