Re: The Acer 3100 Series Laptop battery on light burns...
That battery is exhausted. Best not even leave it in the laptop ever. As all this will do is to create more heat and overload the power system. Best to remove it and hang on to it until you get a new one.

If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods.
try it without the battery on the laptop. if it boots and stays on, put the battery back on and see what happens. If the problem persists, replace the battery. Acer will replace it free if you are still in warranty
Try taking the memory out and then put it back in making sure it seated correctly then start using AC power lead it's probably caused by letting the battery get too low before recharging.Use a start up disc to get it going if you have to. Good luck
have u tried booting the computer with just the power supply hooked up and your battery out? iv'e had the same exact lab top and the battery went bad and the computer wouldnt do anything at all like your talking about. Even if i had the power supply hooked up and the battery. Remove the battery, and try booting it up.
This is such a user error. I had the same problem on my 3100-1718. It was as simple as holding down the Fn key and using the left and right arrow keys to change the brightness... I am a goofball for ever letting this stay dark for a month !
