Hello, I have a Compaq Presario CQ56 with these specs:


Windows 7 64Bit OS

6GB DDR3 RAM (upgraded from 2GB)

250GB 2.5" SATA HDD

AMD v140 2.30GHz Processor Single Core

BIOS Version Hewlett-Packard F.16 15/02/2011  (copied from System Information)


I hope that's enough details, I can find out more if needed.


Not so long ago I decided that I wanted to upgrade from the single core 2.3GHz processor to a dual, triple or even quad core processor. I read the manual for my laptop which said the most this model could handle was a AMD Athlon N370 dual core 2.5GHz. After reading some mroe in online forums I found that someone fitted a   P970 processor in  this model and it worked fine so I decided to go for a Tri Core AMD N370 processor. I ordered it and fitted it this morning but when I tried to boot up the computer the screen was just black, so I put the old processor back in and that booted fine.


Is there a BIOS upgrade I can get for my laptop that will allow the Tri Core processor to work or will I need to return it and get the dual core?


Either the guy who said he fitted a quad core 2.2GHz was lying or there is something I can do to be able to use the processor.

Which CQ56?  Look on the service tag.

Just because the "P970 Quadcore" worked, is no guarantee that an "N370 Triplecore" will work, when only an "N370 Dualcore" is stated to be supported. . They may have differing power requirements, and different voltage requirements.

Hi, i'm not sure which CQ56 it is.


I've also got another problem since putting the old CPU back in, when I plug the charger into the laptop it dosent charge and no charger icon comes up on the taskbare, the light next to the charger port dosent light up either. It has now gone completely dead. Before the battery died everything else was working fine.
