I haven't used my laptop in a couple of days and I had no problems with it the last time I used it, but i tried a few times to boot up my computer. The Sony Vaio screen that displays right before windows is bright, but when Windows boots up, the screen is very dark. I tried to boot up the computer in safe mode, but I get the same results. What is wrong with my computer? If you have any answers, please email me. Thank you.
