    11 replies, posted
Hi, I installed ubuntu 11.10 onto my laptop today, and it seems to make it run extreme hot. The laptop feels abd runs hotter then when I was playing a game on it, even though the only thing im doing is surfing the web or even it just being on idle. Whu is this? And is there a way to fix I The laptop is a dv6-6100ax (i know its a dv6, but I havnt had any issues with it)
Is the fan turning on?
[QUOTE=Jasun;34209355]Is the fan turning on?[/QUOTE] yes it is. It running at nearly 100% all the time, but the laptop still get extremely hot
From what I've been able to tell, the current Kernel lacks proper ACPI powersaving features. All hardware will run at full speed and power regardless. Sometimes, linux will be unable to turn off all devices, causing the battery to constantly drain, even while off.
High temps != High CPU fan speeds... Linux doesn't always have the proper CPU fan speed drivers/settings, so the fan gets stuck at crazy high percentages even if the CPU itself is cool. Got any real temp measurements?

Have you tried installing another DE to see if it's something to do wit Unity (I've had this happen before)?
Install Jupiter, set it to Power saver. [url]https://launchpad.net/~webupd8team/+archive/jupiter[/url]
Run the latest kernel, it has the power regression patches in it. Good luck though, I can't get Kernel 3.2.x to run on my laptop OR desktop without causing a kernel panic. :/
ffs this is going to take hours, compiling full kernel 3.2.1 from kernel.org on a Atom @ 1.66Ghz with 1 physical core and 2 HT threads.

You'd want to compile on a faster machine than an Atom. I've seen i7 machines compile the kernel in under 1 minute. O_O;
To lazy to actually find out what those power regression patches are or if they even exist, 3.2.1-4 running fine here.
