Basically, my old HP Pavillion g6 laptop died around 12 months ago. Recently, I've started to gain knowledge in the PC building world, having built one in January, so I decided it would be a good idea to strip my laptop down and see if I can repair it.

Now, my laptop died of a CPU failure, so I'm wanting to replace the CPU (Intel core i3-370m). I could replace it with another 370m, however the i5-2540m uses the same socket as the i3, so it should work shouldn't it?

Anyway the i3-370. It seems to be held in place with 4 blobs of glue rather than a holding plate like I've seen on most PCs and some laptops. How do I get rid of this so I can remove the CPU?

Thanks guys, although this isn't my first laptop teardown, it is the first one where I'm actually trying to repair it :p

You could try slowly heating the glue up, then when its soft remove the CPU from the socket and clean off the glue.

Hope this helps :)

Thanks for the reply freeman :)

I have a hair dryer which I can put on a really low heat/speed, will give that a go :) Could you clarify whether or not the i5 I mentioned earlier would work?

The i3-370m uses a BGA socket. BGA stands for ball grid array. The CPU has hundreds of little balls of solder on the bottom instead of pins. These are melted to fuse it with the motherboard.

You cannot replace the CPU. (Well, you could if you had machinery which can clean and solder on a new BGA CPU. But you pretty much have to work at a computer electronics factory to have access to one of those, and you'd be answering our questions instead of the other way around.)

Replaceable CPUs use LGA sockets - land grid array.

Yes it would assuming you can remove the CPU and nothing breaks.

Problem is, you CPU is unlikely to be dead.
CPU failure in this case means that one of the solder joints is broken.
Pretty much impossible to repair in home environment.
Easiest solution would be to find a replacement board with CPU or buy same laptop with other components broken but working motherboard.

Look on the bright side at least the CPU came off. sorry the hear it broke :(. As far as the motherboard is concerned make sure it will fit inside the laptop.

Found one on eBay from the same case which I may get. Oh and the CPU didn't exactly come off. I may post a pic if I don't feel too embarrassed :p
