HOW TO GO TO BIOS IN VAIO VGN-FZ4000 - Sony VAIO VGN-CR240E/B Notebook

Sony Vaio PCG and some Vaio VGN Series use the last 7 digits of the laptop serial number to calculate the bios master password. The serial number for a Sony Vaio is often located on the bottom of the laptop on a white sticker. The serial number may also be found by removing the battery and checking in the battery compartment. The link to unlockbiosrecovery.com below works on the following models:
PCG-C, PCG-F, PCG-GR, PCG-GRS, PCG-GRT, PCG-GRV, PCG-GRX, PCG-GRZ, PCG-N, PCG-NV205, PCG-QR, PCG-R, PCG-SR, PCG-SRX, PCG-TR, PCG-V, PCG-VX, PCG-X, PCG-Z, VGN-B, VGN-FS, VGN-S, VGN-T, VGN-TX1, VGN-X

For $20 they use the last 7 digits of the laptop serial number to calculate the bios master password and then email it to you in an hour. They guarantee it to work and you can call them if you have a question.

Those 2 software packages offered by Sony on their web site, (a) ArcSoft Magic-i Visual Effects, and
(b) WebCam Companion Software, may just include the driver necessary to get their packages to
work with Win7 - pick one an install it - if the camera works, you got the driver. If the camera still
refuses to work, then all you have to do is de-install the package, install the other one and
give that a try.

Hi,

Unfortunately, if a VAIO is not turning up after a failed BIOS update, the only option is to flash the original BIOS. This is only done at Sony service center.

You need to contact a Sony service center near your area. it get the BIOS flashed.

Thanks!!!!

Press ctrl alt del butons together. Go to Task Manager and check if any Process is running at 100% or close to that CPU speed. This usually happens if a program or service has failed and the CPU is trying to complete the job. The CPU heating problem should be cured once you have found the program using your full CPU power. Try to uninstall that program completely. If you need it then try reinstalling again after a reboot. Read more at www.fixpcfreeze.com

BIOS upgrades are USUALLY done in DOS. Most times, you need to boot from a floppy or CD that is specific for BIOS upgrade. Some BIOS upgrade software may be apllied through Windows, but this depends on your computer manufacturer.
BTW, if your computer is running ok, DO NOT MESS UP WITH THE BIOS. You may risk ruining your laptop.
IF IT IS NO BROKEN, DO NOT TRY TO FIX IT.

BIOS is gone...u need to change the BIOS IC or may be the full Motherboard...
