Check that all the power apps are installed.<br><br>I had a laptop years ago and did a very custom (this being the problem area perhaps) debian install on it. I kept on running into performance issues and in the end it turned out that I hadn't installed acpid (I think that's what it's called). Which managed many power controls including the CPU fan (which on the laptop was adjustable to allow for power saving), once the application was installed the CPU fan came on and the performance issue (and related slowing down and hanging) stopped.<br>
While a default install of a desktop distro should have everything, sometimes there might be a different requirement controller/api. Or just a bug in part of the kernel code for that particular hardware interface (or in the hardware itself).<br>

'I bought a new laptop battery, and it's already been through a
few charge/discharge cycles. The battery monitor shows the % of
charge correctly, but it shows 0:00 hrs:mins remaining (or 0:00 to
full charge) all the time, and the low battery warning window is
always on the desktop. If I close it, it reopens. With the old
battery, the time remaining and the low battery warning worked
fine.<br>
<br>
How do I get Linux to learn about the new battery, or to reset, or
whatever is needed?'<br>

He asks if y'all have any helpful ideas? I think he is running
Mint 11.<br>
