Both batteries, not just the main one? If that's the case, you need to find your laptop model's support site and see if there is a service manual for it to find out how to get into the laptop.
Both batteries were out for more than 2 hours.
But after two hours I start the laptop and first I must put in the password for the bios.
It is not possible to start a new Windows with the cdrom and do first boot cdrom player.
After 3 times put in a password I get error code 06955.
I find a program and can put in the error code and getting a password.
But also that is not working.
Thanks for your help.
