Windows 7: Questions about replacing HP laptop cpu?

Questions about replacing HP laptop cpu?

Hi, I have an HP g42-415dx laptop with Windows 7 64 bit and AMD Dual-Core Athlon II P340 which I would like to replace for a faster AMD Quad-Core Phenom II P960 from e-Bay.

List of what both processors have in common: THEY ARE BOTH 25 TDP WATTS
--Core Name: Champlain
--Platform Name: Danube
--Microarchitechture: K10
--Technology: 45nm
--Socket: Socket S1 (S1g4)

The only differences include frequency, bus speed, L1 and L2 caches, cores and names.

Can I replace it?
Can I use the old fan/heatsink?
Is there any compatible CPU better than the p960 that can be used instead?

There`s nothing here about an upgrade so I would call them direct.

Even if you could theoretically replace it, there is no guarantee that your OEM's BIOS will accept and recognize the new CPU as it has only a preset list of supported CPUs in it's firmware.

Also, upgrading from a dual core to a quad, even one that has a similar rated TDP, could cause additional overheating issues due to the additional 2 cores that may not be sufficiently handled by the built in fan and heatsink...

You could try to update your BIOS to a newer version to increase the chances of compatibility:-

Didn't think about that, I prefer not to risk my money and my laptop to replace something that's not going to help a lot. Thanks anyways.
