I have an hip laptop and it randomly shuts off. I want to try to trouble shoot before I call it a lost cause. Referred to some great threads on here before so thought I'd give this forum a try. Thanks ahead of time for any help. I have an HP Pavilion dv6500. It randomly would shut off a few months ago, got better but started up again. When it shuts off its sudden like someone pulled the cord on it. After it shuts off I cannot get it to start for quite awhile afterward (20 minutes to 3 hrs if not longer). I can push the power button and the computer will attempt to start but will do the cold shutdown in the middle of startup. Sometimes it can get as far as the windows log on and then shutoff. The shutdown happens at all times, no pattern in my activity. The computer has some other issues, I can't run it without the power cord because the battery is dead (HP said its because I didn't take the battery out when I used the laptop plugged into the wall. Refuse to buy another battery if I can't get laptop to work). My 3 year old spilled milk on the keyboard and it was bad enough the milk came it the USB ports and battery slot on the bottom. Another issue is when I try to change the power battery settings, I can't change it past the lowest performance setting because the laptop overheats. It will shut down within minutes of changing setting. this seriously affects the performance since it has to run so low. But hey, it's a laptop and works for my basic net surfing and word processing. If it sounds like a lost cause let me know. If there's something I can try I appreciate the help.
