I tried to change bios settings and it didn't work properly. Now it won't POST. Just black screen with power indicator light turned on when I start the laptop. So I am trying to reset the bios settings. I disassembled it but there's no CMOS battery or any connector pins on the mothboard. I tried taking out the normal battery, decharging and then assembling and powering laptop up again but it didn't work. Does anyone have any idea how to reset bios for this motherboard?
