1. Try the generic reset noted in the Laptop Troubleshooing Forum.
SHORT VERSION. Power off, remove AC, battery, press the power button for 60 seconds, slip in battery, apply AC and try again.
2. Replace the CMOS battery. A few machines will not start with a dead one. At 1 to 10 bucks I think this is a good GAMBLE. Some can't gamble?
This computer has not functioned for many years but I loved it. It will not come on. Is it worth repairing ? Is it still usable.
There is only a black screen when I try to turn it on.
