x230 not booting with new CMOS battery installed
When I install the CMOS battery (new) the laptop won't boot...completely dead. This happens even when I re-install the old battery (I have checked that the battery is full)
If I remove the CMOS battery the laptop turns on normally.
I can use it like this but if the main battery runs out I have to change the date in BIOS every time.
Does anyone have any idea why this is happening?
