CMOS battery also know as RTC battery | Laptop Parts

February 22, at I have a Sony Vaio -P series laptop model: In some laptops the CMOS battery could be easily accessed from the bottom, as it sony vaio vgn – fs790 on the picture below. I would like to know how to disassemble the laptop to get to the CMOS battery. I discovered one of my RAM chips was bad, indeed. Turn off the laptop, unplug the AC adapter, remove the main battery, disconnect the CMOS battery and wait for about 10 minutes.
