You have a reset button under the battery . Depress this button with a pencil . I would hold it down for two minutes replace the battery and see if that works . You dont know if its in DOS if your monitor dont wotk . You can also try to rove the keyboard carefully and remove the internal battery . Its the size of a nickel . Leave it out for 15 minutes this will reset your system . You might want to get a new internal battery . There is one screw in the middle of the bottom of your laptop for the keyboard take it out then take a small knife to pop the built in clips all the way around the keyboard . There is a plate between the monitor and keyboard this will pop out with a small knife just like the keyboard it also has clips . Start from any side on both the keyboard a.d plate a.d work your way around . The plate has to be the first to remove . You will also have two or three small screws at the top of the keyboard . Be careful you dont pull out the connection ribbon . It should unplug . Good luck . I had the very same laptop so ive done all this with working results ...

Computer slower when plugged in the wall than running on battery

I don't have experience on this laptop. But can you check your power management application from your control panel. It could be possible that this management program is taking more CPU resource. This is just an idea. I could be wrong.
