My laptop computer has been acting strange lately. The strange issue I have been having occurs after I shut my computer down and turn it off. When I shut off the computer the hard drive light comes on and it continues to run. If I unplug it, it will drain the main battery down to nothing.
The details:
Compaq Presario V2000
1.86 gHz Pentium M Processor
Windows XP Service Pack 2
1gB of memory

Any suggestions?
Other than get a Mac, which may happen anyway.

UPDATE
Just a few weeks ago I bought a new Inspiron 1525 from Dell. I am getting used to Vista slowly and enjoy the rather large amount of hard drive space I have now. Thanks for your help and suggestions!
