Hi, i have a compaq presario 2500. i got a problem in my system. my system auto tabs itself cause of which i cannot do nything. whenever my system starts, after the booting screen it goes into battery callibration mode. from there i have to press s(option to skip callibration) many times to get to the windows logon page. after i login the tab function works automatically, i mean the pointer keeps moving on the icons of the desktop automatically (open a page and press the tab button and hold it for a few seconds or minutes and see the curser moving from up to down like tht i mean to say ) and i need to press the tab button to stop it. . i have tried formating system but nothing happened and i have even calibrated my battery. plz help me out.
It sounds like a hardware problem. Try getting a different keyboard and mouse to make sure there is not a button stuck somewhere. If not then i would wipe the drive and re-install the OS. Or do a recovery at boot up if running Vista.

Well auto shutdown issues have no any actual solutions because there are many reasons that causes this error. the battery located in the motherboard of your laptop may down . or you might be experiancing a heat related issue.
go to control panel -device manager and see if you have all the latest drivers downloaded and if u dont then i would try and update them. if that doesnt work search up the specific driver u need online and download and install it.
you should be able to find the model at the back of your notebook. It is a white sticker,where it have serial number of
your notebook.There you'll able to see the model you're using .If no then it should be on front -right handside ,below keyboard but maybe be it's has been accidently taken off.
i'd say first try a known working ac adapter and if that Working AC adapter works and the system detects the battery well, then it could be the ac. If not then try to borrow a working battery to get your final conclusion. if the working battery still doesnt work properly, then it could be the system motherboard. If battery and ac adapter (working) are not available, then check the BIOS and see if it really doesnt detect the battery. try flashing the BIOS and still if that fails, then replace the battery.
