My Arch Lappy HEATS a LOT...


Hi...

So, I installed, and upgraded Arch 2010.5 in a lappy, and this heats a lot... CPU is not at high gear, ( as conky and top point out ), anyway, this heats quite a lot when connected to AC Power...

Any hints...?

I have an equal lappy with Slackware64 13, Kde... does not heat that much...

Top does not give you the information that you want (clock rate); does conky give you that?

Is there any sign of the clock speed being scaled down? do you use a GUI (which?) and how is its power management set up? It is possible that the machine is set to always go flat out, when on AC power.

Which governor do you use?

You are suggesting that this is better when on battery power?

Hi @Salasi, @Mr-Bisquit

So...

I installed cpufreq ( did not configured it yet ) and cpufreqd;

My WM is IceWm ( think i will dump it though... the configuring tools in AUR are deprecated, and wont compile in 2010.5... , and I cannot set my menus... does menumaker do the job...? If it does not, I may ditch IceWM for Flux...)

Made a small test, running on battery... it still heats up, although not so much as on AC, although on Battery it heats more than Slackware on same HW on battery.

Did not install Nvidia driver yet ( if it has any thong to do with it... )

I am running this deployement test in an external USB HDD, so the HW is the same, any differences in heating may only be attributable to SW configuration, IMHO

For Slackware, lappy's OS i have /dev/{sda1 sda2 sda3} and Arch /dev/{sdb1 sdb2 sdb3 sdb4} ( I keep a snapshot of Archx86_64 repo ins /dev/sdb4 )

This may seem a bit obvious, but have you tried getting an air duster and blowing it into the vents? One laptop will heat more than another if it's dustier inside.

Hi Cantab

Same lappy, two Distros;

One in Lappy's HDD ( aka /dev/sda ), Slackware.
Other in external USB HDD ( aka /dev/sdb ), Arch.

When running Arch with IceWM lappy heats more than when running Slackware with KDE

Ah, in that case then yeah it sounds like a power management issue.
