I have a Sony vaio with intel HM76 is it possible to upgrade from a i5 2450m to either a 2nd gen i7 or even better 3rd gen i7, according to intel the hm76 supports both 2nd and 3rd gen cpu's. My service manual has the block diagram for the motherboard for Processor (IVB) Dual/Quad Core (SNB) Dual Core Micro-FCPGA-988B (988-pin rPGA socket) TDP: Dual/Quad Core (35w) 37.5mm X 37.5mm. For HM76 TDP 4w 989 Ball FCBGA PCH (PPT) Panther Point-M
If any i7 cpu is supported what ones could I choose from?
Since you own a laptop computer, this type of compatibility depends on the computer manufacturer's BIOS. In other words, you need to make sure the BIOS support the new processor by contacting your computer manufacturer.
The link below provides a list of tested processors for your chipset model: ARK | Mobile Intel® HM76 Express Chipset (Intel® BD82HM76 PCH)
I recommend checking with your computer manufacturer for more information.
