Sony VAIO VPCF13 Series & i7-9x0XM

[thorboy86]

Hi guys,

I bought an I7-920xm processor for my Sony Vaio laptop but it doesn't boot up.  I know it may be an old subject since anything I search and find on this site is a couple years old but I thought it won't hurt trying to ask.

Everything I have read so far says the Sony BIOS from AMI doesn't allow the use of the extreme processors.  A couple threads on here mention that a custom bios can remove the limitations to use the extreme processor.

Any help or even point me in the direction of another thread to go through is greatly appreciated.

BIOS reads as follows

MODEL: VPCF13NFX
BIOS VERSION: R0190Y9
EC VERSION: K0190Y9
ME VERSION: 6.0.30.119

Also saw other people post the original BIOS from Sony

Thanks!

i7-940XM and i7-840QM use common microcode.
I think this laptop doesn't support CPU with TDP=55W because of hardware limits of power subsystem. On motherboard, not PSU.

Power subsystem is not cooling subsystem.

No.
