I've been having this odd problem lately and was wondering if anyone out there has any ideas as to (a) cause and (b) cure. When my laptop starts up (Win2000) the system date is wrong. It's always off by a month. Usually, it has moved on exactly one month. The most recent occurrence (this morning) was different. The month changed back to January and the clock was exactly an hour slow (making me think the clock reverted to GMT for winter month).
I've had this laptop for 3 1/2 years (Dell Inspiron 2500). Based on what I've learned over the years and what I've been able to find online, I suspect it's the CMOS battery. What I want to know is: do laptops have a CMOS battery and, if yes, how hard is it to replace one?
Any help would be greatly appreciated.
