I have a Compaq CQ60 laptop shutting down after about 20 minutes, starting with a 100% battery. When it shuts down, it's at about 70%. It only shuts down on battery power. Plugged up, it's fine.
I have trouble believing it's a battery problem. It's only about a year old and has only received moderate use. I've tried the calibration thing with no luck, and I've also done the thing where it should pop up a warning at 50% power or 10% power, and that warning never comes up because it doesn't get that low. After it shuts down, I reboot to find that it's still at 70 or 80%. Then it very quickly crashes again.
What to do? Replace the battery and see if that helps? I'd like to think there was a software or OS thing I could try first.
By the way, coreTemp says the laptop gets up to around 70 or 80 degrees, but usually is between 60 and 70 when it shuts down. Actually, if it's overheating, I should be able to let it cool down for a while and then it should boot up fine. Will try that.
I'm open for suggestions.
Ok, I'm adding this: It just shut down after 20 minutes of sitting on the glass-top coffee table. Actually, the right edge is hanging off. It was at 82% battery power and had been that high for at least the last 10 of those minutes. It was about 56 degrees. I'll wait 20 minutes or so and crank it back up. We'll see what it does then.
Another addition: I just installed coreTemp on my Compaq CQ62, which is about 3 months old. It's been running 38-41 degrees steadily for a while during web surfing and typing. The CQ60 was 56 degrees just sitting there doing nothing. 56 doesn't seem too hot, but it is considerably warmer than the the newer laptop, especially sitting idle.
