How long should the CMOS battery (the [usually] coin shaped battery [usually] mounted on the mb) last? I am finding that my Toshiba Sattelite laptop loses the clock and CMOS settings if it is powered down and unplugged more than a few weeks.

I guess it ought to be more than 2 years. -- Crowd-funding is for money, crowd-publishing is for mankind. http://www.supermanpost.com/

And your problem suggests that you have a chargeable battery of bad quality, because normally a downtime of a few minutes is enough to cause problems with a bad battery. Your few weeks suggests that the battery is charging when the computer is powered. In which case a normal battery might not like that.

My old Windows 98 home PC still has the original battery and it continues working after 15 years!

If a laptop is to be idle for more than a few days, it is prudent to remove the power supply battery: otherwise it may be configured to keep some functions activated, and thus deplete the battery (and perhaps put extra demands on the CMOS battery as well.) -- Don Phillipson Carlsbad Springs (Ottawa, Canada)

Any rational design would let the main battery supply all functions when available. No need to discharge the CMOS battery when not necessary.
