My moms laptop ( Toshiba running Windows 7) keeps saying password is incorrect. She says she was on Southwest Airlines when she was last on it, then circumstances prevented her from using her computer for a month. I picked up her computer for her today, it had a black screen so I just shut the lid and brought it to her. Upon opening, it went to SW Airlines, she asked me to get her on my network. When I went to get her in my my network her screen showed her desktop. I got her on and walked away. When she got back to her computer the screen was black again. She booted up and it said her name and that she was logged on but it required a password and she put everything she can think of and no go. Also, 25% of the time when she hits enter it will say welcome for about 45 seconds then come up with incorrect password!!!! Any bidea why she cant log on?? Was it because the battery died and it powered down incorrectly?? HELP!!! She needs her computer for business....her livelyhood depends on it. Thanks all.
