I have a Toshiba satellite E45t-B4300. Up until yesterday it was working fine. Then I tried to turn it on and it just flashed the power button every 4 seconds or so and didn't do anything. I assumed the battery was dead or something, so this morning, tried to plug it in and turn it on. Same thing. I looked at some suggestions online, and tried taking out the battery, holding down the power button to drain it, then putting battery back in and trying to turn it on. Now, I just get one quick flash of the power button when I try to turn it on (it's plugged in) and then nothing - though I just tried again and got a long light up, like it was turning on, but nothing happened. Then it went back to the short flash when I tried again. Any suggestions?
