How To Replace Rtc Battery In Toshiba Satellite. This model of Toshiba Satellite lacks an access panel on the bottom of the laptop so I removed the bottom panel of the laptop. Answer 1 of 6.
The Real Clock RTC battery provides power for the inernal real time clock and calendar. I have never seen a motherboard without a CMOS battery before. However nowhere on the motherboard can I see any coin cells that would identify the CMOS battery for me.
Michelle Im sorry but the satellite laptop I have ie C55-B5270 does not open up like in the video you suggested and does not have a CMOS battery in the location shown in the video.
So the only thing keeping the date and time is the main battery. Then it is time to change your CMOS RTC coin battery. If you let that battery run down you get. The battery keeps the Notebooks date or clock settings running in the BIOS located on the motherboard.
