if i disconnect my computer with the from the wall or AC current my bios gets reseted. i get the message "press f1 to recover your bios". im using a rog maximus 6 formula z87 cipset. i know it could be a cmos battery problem. but the clock is not being reseted as you expect to happen if your cmos battery is down. i want to be sure that i need to change the battery because its really a big hassle to open that thermal armor.
