Dear all,I have been running Fedora since Werewolf. Recently, I had to start dualbooting Windows XP because of collegework, and one of the things I noticed rather fast was how much cooler my system runs under XP. Now I want to know why.On F16, my system will sometimes have the fans running at medium-high speed even while idling and just Epiphany running (for Gmail and FB chat...this does not to my knowledge generate anything else but sporadic cpu bursts and occasional I/O). The HDD becomes unreasonably hot (despite iotop not reporting significant disc activity apart from syslog and some Gnome-specific daemons), and the CPU (Core2Duo) and VGA (Intel HD4500) also seem to be running needlessly hot.Does anyone know of a good way to debug exactly what is causing my system to idle in this way? Obviously something somewhere is causing my hardware to idle in a very wrong way, and it would be helpful to nail down just what the cause is.Thanks in advance!Chris
Addendum: more than a few times the laptop has actually shut down due to overheating, even while not running on overddrive (just Epiphany with YouTube, Gmail, FB, Eclipse and some non-intensive stuff running). This sort of clues at least me to believe it might be VGA-related (it the fans normally go into overdrive when Youtube is up).
I am running an HP Probook 4510s if anyone else has had similar issues.
