I recently bought a used acer 5552-7819. There is a bios password in it. I found out after I got it home. The former owner does not know what the password is. I have spent 2 days reading (till my eyes bleed) about this issue. So for I have tried.. removal of mother board battery, shorting the battery, removal of both batts and pressing the power button, tried esc on boot, f12 on boot, f10 on boot, f8 on boot, upgrading the bios to 2.4 and then changing the values in the ini file.. so all the values have been to 1 from 0 to flash the bios on start up, ( which is part of this method [URL]http://www.citronix.net/blog/how-to-remove-a-bios-password-from-an-insyde-h2o-efi-bios/[/URL] ) I have tried cmos wiping tools etc etc etc I mean I have tried everything I have read and nothing has worked. Does anyone have a method for removing the bios password this guy put in? The problem is .. I cant access the bios to change to boot priorities. Thanks for the help X
