I have an Inspiron 1721. The computer shut down and will not power back on. Nothing happens when you push the power button. All of the LED's on the bottom of the battery are lit green (constantly). If you push the battery check button the two LED's on the end and the one in the middle (3 out of 5) flash green several times and then the LED's turn off, but come back on in about 2 seconds. Plugging in a known good AC adaptor cause the light on the adaptor to go off and it must be unplugged to be reset.
Any ideas on the problem?
