This was very common problem with laptops with Celeron CPUs and still 
is. And for them, it seems like if you pull out the battery for a few 
seconds after it has been shutdown. Then reinsert the battery it was 
usually just fine. The story I heard was that most Celeron CPUs was not 
totally shutoff. They have different sleep modes and call them S1, S2, 
etc.

Later I started to hear other complains about the battery draining after 
a couple of weeks in other CPU equipped laptops. I can't swear to it, 
but I believe they are all Intel CPUs. And it wasn't any of the Centrino 
types I don't think, but the I3, I5, or I7 ones I believe. So what type 
do you have?

I know this battery draining thing is a big issue for many. Although it 
normally doesn't bother me at all. As I normally don't have any 
batteries in my over dozen laptops anyway. And when I use one, it is 
usually on AC on an UPS supply and still without batteries. Only when I 
am running portable, do I ever have a battery installed.
