So I have a HP Pavillion zv5320ca that likes to suddenly turn off now (not shut down...it just goes black and turns off like you pull out the AC connector). It starts to do this about 3 weeks ago. Before this, there was no problem for a few years. My HP Laptop is 4.5 years old today.
It does this with the battery in and the battery out, hooked up to outlet power. About 3 weeks ago, I was typing on the keyboard and suddenly the battery icon appeared even when AC was plug-in. I have to unplug and re-plug the AC connector at the back of laptop, and then the battery icon would disappear. (Now my old battery doesn't keep a charge anymore).
I know it isn't a heat problem, because I can turn the computer on first thing in the morning and it will sometimes shut off within 4 or 5 seconds. And my heat fans are clean (I clean them every 3 months). The CPU was not feeling hot at the bottom, and my Notebook Hardware Control software showed CPU temperature as +42C when this happened.
So the nature of it is, I can turn the computer on, and sometimes it shuts off a few seconds after that, sometimes in the middle of the XP loading screen, and sometimes while Windows is loaded.
I can use it for 8 hours and have no problems, or sometimes it will shut off 3 or 4 times within 20 minutes...or I can keep trying to turn it on, and it immediately shuts off. I need to re-plug the AC connector before the problem goes away, only to appear again later.
What is going on? Anyone has any advice to solve this problem?
Thanks in advance.
