After used for a year I found some strange problem often happend to my VGN-SZ. First I think maybe the hardwares in laptop unstable. I tried to fix it myself by replug them but can not. So I asked in yahoo answer and some one say that : my laptop bios can not prefectly support the second memory bank and Sony VGP-BPS8 battery that I just installed a month ago.

So I should update the Sony VGP-BPS8A BIOS to the newest version. I go to the sony.com to get the VGN-SZ latest BIOS update and search the "Flashing the laptop bios" in the internet. Then I flash my Bios by myself. Maybe you can get some helpful info in the following steps:

If a BIOS update program CD with a new system board, flash BIOS from the CD. If you do not have a BIOS update program CD, flash the BIOS from the disk.
