BSOD when changing AC mode to battery mode vice versa!!

Hi, I dunno if anyone have this problem. Last night, I was about turning of my laptop, I accidently pull off the power plug of my laptop, Even though the battery is till full, It showed a BSOD. I thought it was just some random crash, but when I turn it back on - on battery mode and when It completely loaded, I plugged the power plug in and BSOD happened again. I reinstall the windows, checked it still have the same problem. I'm still using vista business OS and change to it. I checked nothing happened. Any1 know is this because of windows 7 or my laptop?

What ever you have done, other than upgrade or clean install, after, is jammed up.
1. recommend that you run SFC /scannow and see what is corrupt if anything.

2. remove all the updated drivers. simply go thru system -> device manager -> located click delete every driver for ever device your have,
(no they are still there until you reboot,)
3. then close down to desktop.
4. shut down all running programs.
REBOOT
Now let Win7 find and restore every driver.... plz do this while in AC MODE.
after your back up, unply the ac - which ever way you want. YOU SHOULD NOT GET A BSOD... if you do. then attach the dump file in compressed mode.
during storms I use my laptop - why because if the power goes off. i loose nothing, the battery takes instantly over and i can closedown at leasure.
tested with
Windows 7 Ultimate - Win7 Home Premium - Vista SP2 Ultimate never have I had a BSOD for simply unplugging. from AC or plugging AC.

I just figured that out that for some reason the lastest bios of my laptop which pre-set the memory of my graphic card up to 128Mb while my old bios set only 32Mb. I think thats the reason why i got BSOD since after i roll back the bios it is fine now. But I am just curious that is it because I run 64x while my vista run on 86x. But anyways I made a clean reinstallation and i accidently delete all the dump file. Thanks for your help. CHeers guys
