About a month ago, when I went to turn my laptop on, the only thing that came on was the power button and the caps lock button blinks twice repeatedly. Once in a while I can get it to turn on if I try different combinations of taking the battery out and the power cord and holding down the power button down for 15-60 seconds. I've got it to work with and without the battery in it. I've tried every solution I've found on the Internet and none of them have worked more than once.
