My laptop is getting hot with LMDE
Hi,
I installed LMDE 64 bit a week ago or so and I has been very satisfied with it. It feels very smooth and good looking compared to my former OS, Mint 7. And the updated repositories are just great and actually my main reason for upgrading as Mint 7 worked very well for me.
One thing is bothering me, though. My Lenovo T500 laptop is getting very hot and the batteri life is poor. This was not a big issue before. With Mint 7 it got warm, but not really hot. Now I have to sit with a pillow on my lap to avoid getting fried
What could be the cause of this and how can I resolve it?
Thanks,
Martin

Re: My laptop is getting hot with LMDE
Have you installed the driver for your video card, if it takes a proprietary driver? Have you run the command TOP in a terminal to see if something is pushing your CPU to 100% or close to it? Other things to check is that your CPU Frequency is properly governed. I think the default setting is ondemand, which drops you to about 50% CPU speed until demand is higher, then it automatically jumps as needed. You can check what it's set to by in a terminal. If it says within quotes anything but ondemand, it's possible your system doesn't support frequency scaling or the setting is incorrect.

are you using 32 bit or 64 bit? LMDE

The video driver could be an issue. I think I remember I installed a proprietary driver on Mint 7 but the system was so kind to suggest the installation using the program "hardware drivers". I do not see a similar program in LMDE, so how do I install the driver?
Is this setting correct?

sudo cpufreq-info | grep ondemand

The governor "ondemand" may decide which speed to use

Re: My laptop is getting hot with LMDE
sorry I missed that part. I heard that running Liquorix Kernel helps control the heat factor if you are interested

I am running this Kernel and My system runs really smoothe

if you too have ATI then try this:

Re: My laptop is getting hot with LMDE
marlar,
running a laptop with a pillow underneath it is guaranteed to make it run hot, as the pillow will severely restrict restrict its air flow.
I know that you said that it was already running hot, but still loose the pillow.
Best regards Keith

Re: My laptop is getting hot with LMDE
Yes, I know. I only grab the pillow when I can't stand the heat any longer, and if I have to sit for a prolonged period, I actually have a "laptop tray" with a soft cushion and a hard top. I bought that for my old laptop which as it aged got hotter and hotter and eventually was a great subsitute for a coffee warmer if I turned it upside downtinca wrote: running a laptop with a pillow underneath it is guaranteed to make it run hot, as the pillow will severely restrict restrict its air flow.
I will see if I can find a driver for my video card. Maybe that helps.
Re: My laptop is getting hot with LMDE
Sometimes, it get hotter because of dust collected over time and prevent proper ventilation.
Perhaps check and clean those dust also.

Re: My laptop is getting hot with LMDE
This is going to be a long post!
I suffer from this problem, my toaster (Dell Inspiron N5010 Core i5, ATI mobility HD5000) is relatively new and runs very hot. Along with the usual advice about keeping the vents clear:
Check cpufreq is loaded (mine wasn't) I have sudo set up:
If you don't get something similar:
Mine looks like:
I had to add the line CPUFREQ_CPU_MODULE="acpi-cpufreq" but yours may be different, I had to Google.
Reboot and then run
There is a gnome panel / avant-window-navigator applet that can control this.
Finally:
and play with the values, mine currently looks like:
This is the sum of my knowledge!!!!

Re: My laptop is getting hot with LMDE
Yes, that's the correct output. Ondemand is set by default and appears to still be set on your configuration. I would lean toward the video driver as a best guess. Using the open source drivers (I believe) still throttles GPU's to 100% regardless of the use/non-use of the machine. I have not had to get an nVidia or ATi driver going on LMDE, but you can look up the Debian Wiki and Debian forum for how to do so if there is nothing on the Mint forum to guide you. Configuring the video driver should be identical to Debian AFAIK.marlar wrote:I use htop and that reports nothing unusual.TBABill wrote:Have you installed the driver for your video card, if it takes a proprietary driver?

Re: My laptop is getting hot with LMDE
I have downloaded the latest ATI driver for my card.
If the installations fails and screws up my system, how do I recover the existing driver? Should I do anything in advance to facilitate that?

Re: My laptop is getting hot with LMDE
I had a problem with my T61 getting hot. It turned out to be the fingerprint reader.

I also open up the machine and disconnected to fingerprint reader cable.

Liquorix runs 10 degrees Fahrenheit cooler than 2.6.32, the current Kernel in both LMDE and Saline OS.
Re: My laptop is getting hot with LMDE
The article you link to mentions the fingerprint reader itself getting very hot. Here it is the left side of the laptop. So I guess it is not that.jimmm33 wrote:I had a problem with my T61 getting hot. It turned out to be the fingerprint reader.

Re: My laptop is getting hot with LMDE
Thanks, but I am just a bit scared of playing with the kernel. Can I undo a kernel upgrade if it goes wrong?
