Upgrading laptop processor

I have found a intel core i7 octa core (with Intel vpro) in a screen damaged pc so i am interested in upgrade my current i5 dual dual core processor.

I have been researching a little about What does one have to consider before upgrading my laptop´s CPU, and i have found that the only i need to verify is if the new procesor is compatible with the actual socket.

I want to know if this is the only consideration that i must have when installing the processor and what may happen If something goes wrong?

  • Check that your CPU is actually replaceable - in laptops they're quite often soldered on.

  • The socket, chipset and BIOS would need to be compatible with it. Socket and Chipset are easy enough to verify, but the BIOS is going to be a lot more difficult.

  • you also need to make sure you buy thermal paste and scrape the old stuff off of the heatsink

Things to check before upgrading a CPU in a laptop:

  • Does the BIOS/Firmware support the CPU that you want to put into your laptop?
  • Does the chipset & driver support the CPU you want to use?
  • Does the soxket type on your motherboard match?
  • is your current CPU fixed in place (is it user replaceable)?

Considerations while installing:

  • possibly voiding any warranty you have left
  • you must earth yourself (get an earthing band) to prevent damage to your old and new kit as well as the motherboard
  • get replacement thermal grease/paste and make sure all the old stuff is thoroughly removed and discarded
  • if you have to reverse the install, ensure that you replace the thermal paste for the old CPU regardless
  • Update BIOS, Chipset drivers BEFORE you upgrade

Possible fallout from a bad install

  • you may damage your new CPU - you should be able to reinstall the old one. Make usre you are earthed
  • you may damage the old CPU - lets hope your new one works. Make sure you are earthed
  • you may damage both CPUs - you need to get one of them replaced (hopefully under warranty)
  • you may damage your motherboard - time for a new motherboard/laptop
  • new CPU doesn't work and reads as "not supported" - you've either forgotten to update your BIOS/Chipset or have damaged the new CPU. Reinsert the old one, do a driver/bios update and try again. If it still fails, time for a new CPU.

This is far from exhaustive but will hopefully give you something to go on.
