I can not find the network adaptor driver for my sony vaio pcg-8a1r laptop. Or figure out what company even make the network chip in this laptop

AC Adapter Power Supply Charger Cord for Sony Vaio PCG 7F1L PCG 8A1R...

Bios passwords on laptops are only over rode by the the manufacture. This is because they are easy theft items. IBM for instance have a government contract so they will never offer you support for that. You can prove ownership to Sony they may have a master password. Good luck though not heard any company yet that will give that info over the phone. There is NO work around for a that other than Sony doing it.

Hi



BIOS passwords can be reset in two ways,
1. using software 2. using hardware.

I would first try resetting using software, here are two software's to reset or retrieve BIOS passwords.

!BIOS - is a PC BIOS toolkit offering password removal/decrypt and BIOS settings modification/backup/restore.

CmosPwd - Cmos password recovery tools

Please let us know if it works

To reset the BIOS password read the information from this link: http://www.fixya.com/support/r7229632-reset_or_remove_bios_password

Hi, im sure the PCG-K315M dont have a built in wireless card, You can buy a Usb wireless card for about 20-30 pounds from any shop. If your laptop did have wireless onboard there should be a switch on one of the sides of the laptop,

Have a good christmas
