Hi there Recently my surface book downloaded an automatic firmware update which bricked my device. Microsoft are denying responsibilty so I am looking into alternative ways of fixing it (there’s a whole thread about the issue linked here, several others have the exact same issue) So I have two questions: Would it be possible to reset the bios by unplugging the main battery inside? (Similar to removing a cmos battery on a desktop motherboard)If the above answer is no, or a reset does not work - which chip contains the bios on the surface book (As I saw there were several flash chips on the teardown guide) and where could I get a suitable replacement? Thank you in advance!
Removing the battery for a few minutes should definetely reset it. You could also try the ‘‘hold volume up+press power button’’ before you start digging for the battery. With either one of these you should be good to re-configure your bios.
