I have F22 on my son's Optiplex 780 ultra-small form factor. We seem to have a variety of (maybe related) power management issues.

First, the fan often goes full-speed and starts making lots of noise. Usually this is when the computer is actually doing more work, like running Minecraft. Sometimes it happens when watching Youtube videos. Since these are the two main things he does with the computer, it pretty much always happens eventually.

Second, when this happens, and he then suspends the computer, the fan stays on during suspend. It never quiets down. So I don't think the computer is suspending properly.

Third, if I hibernate the computer, the fan shuts off, but the computer actually shuts down--when he returns from hibernation, he has to log in to a new session, his apps have all shut down, etc.

I used to use this computer (several years ago--it was probably F16, maybe 18) and I don't recall these issues, so I believe they must be fixable.

I tried installing TLP, not expecting much from it on a desktop, but figuring it wouldn't hurt, and it didn't appear to change anything.

Any advice about where to start with this?

Thanks,
Matt
