CMOS RTC Battery Toshiba Satellite M45 M55

[CRBJRB]

Hello,
I need to replace the CMOS battery in a Toshiba Satellite M55-S135 not sure the best way to go about it.
Every time the battery goes dead I have to reset the time & date.

You can check under the panels on the bottom side of the laptop to see if you can access it that way. If not, you may have to tear the whole works down. If that is the case, have a look at the disassembly guide at the top of the forum here.
