Processor replacing

Posted 28 July 2015 - 03:00 PM

Hi,

I have an old laptop that still ran perfectly but now the cpu is almost dead, when i opened the laptop i saw that the internal processor looks the same as another cpu i got from a desktop. So i replaced it but the only difference is that the top chip is bigger on the desktop cpu, but does that matter? If it fits could it work or will i just blow my computer? Because i have no idea i dont want to try it out.

Thanks


(See pictures for difference)

desktop pins: https://drive.google...eGpCSmkxbzNwdUk
laptop pins: https://drive.google...0ZfdW1vSm8/view
desktop chip: https://drive.google...VZzZ0JaTXM/view
laptop chip: https://drive.google...zR5NG45T2M/view
CPU motherboard: https://drive.google...nhIVXVSdGc/view

Is This A Good Question/Topic? 0

No dont do that. I dont know what happens but its not good.
Theres a BIG difference in Desktop CPU and Laptop CPU.

You should buy a new CPU.
If you need advice about buying a new cpu then i can give you some advice.

Oh yes you can buy some laptop CPU's online or for me in a store nearby. But i dont know if there is a IT store nearby and if they sell mobile processors. You should ask them.

Hahah lol an intel core dual :P/>
Mine is good for a $145 USD xD but its not a super good one. http://www.aliexpres...-i7-3612qm.html
Also aliexpress.com seems to sell some laptop cpu's but keep in mind it needs to be compatible with your motherboard.

No its nearly impossible to replace a soldered cpu. since its soldered by a computer with a nanometer precision. The precision it requires is not possible to perform by hand.

Mobile cpu's use less power. As others have stated, they are no where near compatible. Also, I don't know how you arrived at the idea that the fcpu is "almost dead". It either works of it does not. The cpu will not gradually fail. If your laptop is slow, it is because you are over utalizing the resources.

Laptop cpu's are not soldered the gpu is. They use a bga (ball grid array) for soldering & require that you have the stencil.

@matteke Rule of thumb, if you don't know the difference between the cpu & the gpu, you are not doing enough research.

With gpu failure, it's easier to replace the entire logic board. However, if your laptop suffered from gpu failure, most likely it was designed with poor cooling (a lot of them are, anymore) & others of the same model / design type will also fail. The logic boards of these large failure number units generally are more expensive. HP's had this problem for years.
