Compaq M2000 dead laptop?

Hi all,

I have a Compaq Presario M2000 laptop that
was sitting for a couple of weeks. I plugged in
the adapter and pushed the power button and
NOTHING, no lights, no beeps nothing. So
I removed the battery and put it back in and
tried again, nothing. Then I took the battery
out and tried to fire it up, nothing. Do laptops
just go dead for no reason? Does this one
need the battery to complete the curcuit and
fire up? I have the feeling that even if I try a
new battery I will get the same result. Any
ideas? bad switch, bad adapter anything
else? Is this a common occurance for this
brand/model?

thanks,
charles......
