I have dell latitude d630. Fresh install of w7 ultimate x86. (bios mod) System run smooth, no problems. BUT: When I disconect the AC adapter, the intel media graphics accelerator driver stop responding, and tryes to restore. It happen almost evry time. It wont restore eigther, so I end up with BSOD. After reboot evrything is fine again, until I unplugg ac adapter again. I tried to update driver, and install older driver, uninstall driver.. but, no luck.. Same problem when I use the driver from WU. I notice when i connect the ac adapter, screen goes black for 2 sec before all is normal, and the same when i disconect the adapter.. Black screen for 2 sec before desktop goes crazy The bios mod include slic 2,1 and no problem get activated. I wonder about the bios could be corrupted at some way, and this is causing the problem??? Its an A17 bios modded whit slic 2.1. Downloaded from another forum, because I couldnt tind it on MDL.
