Overheating in Linux Only & extremely poor battery life

[dakshsaraf]

My laptop body gets really hot when running linuxmint. I have tried tlp, thermald, cpufreq, asus-fan-control, powertop to resolve the overheating and battery issues but none of them have worked.

The laptop does not face any issues when running Windows. Running Linux, the laptop body overheats even in idle even though psensors shows that the temperature is not extremely high.

Any rectification for the problem. I am afraid that this might cause some damage to the laptop and reduce its life.

hello dakshsaraf,

iam running my kubuntu 20.04 - and in idle (just writing mails) i have the following values:

$ sensors
iwlwifi_1-virtual-0
Adapter: Virtual device
temp1:        +34.0°C  

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +55.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +55.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +47.0°C  (high = +100.0°C, crit = +100.0°C)
Core 2:        +50.0°C  (high = +100.0°C, crit = +100.0°C)
Core 3:        +47.0°C  (high = +100.0°C, crit = +100.0°C)
Core 4:        +49.0°C  (high = +100.0°C, crit = +100.0°C)
Core 5:        +50.0°C  (high = +100.0°C, crit = +100.0°C)
Core 6:        +48.0°C  (high = +100.0°C, crit = +100.0°C)
Core 7:        +48.0°C  (high = +100.0°C, crit = +100.0°C)

BAT0-acpi-0
Adapter: ACPI interface
in0:          15.85 V  

asus-isa-0000
Adapter: ISA adapter
cpu_fan:     1800 RPM

pch_cannonlake-virtual-0
Adapter: Virtual device
temp1:        +47.0°C  

acpitz-acpi-0
Adapter: ACPI interface
temp1:        +53.0°C  (crit = +103.0°C)

so as far as i see the values seems very similar.

if i run something that is very power-hungry my fans are spinning up very noticeable! in this idle state they are barely noticeable..

have you experimented with deactivating the big graphic card? i currently use the nvidia drivers - and selected the PRIME-Profile On-Demand - i have not tested it really - in theory this should save on battery a lot and also reduces heat generation by the graphic-card.. → it could be that some effect on the desktop is rendered by the graphiccard and therefore generating heat...

so maybe you have more chances for a idea what is going on by ask this in an linuxmint forum. and what is about just testing with an ubuntu live-system from a (fast) usb-stick? just to chekc if this is linuxmint related or if the same happens with an live-ubuntu?!

in general - i think the heat should not damage the laptop - the hardware should protect itself - but you are right in that high temps will reduce components lifetime..

also have a good read in the #6 issue. maybe its related.

Hi, I just purchased a UX581LV-H2018T and directly installed ubuntu 20.04. For me the fans are working out of the box!

I do however notice that the laptop heats up very quick when the nvidia card is turned on. I just disabled it by using sudo prime-select intel and only enable it when needed. This problem isn't specific to this laptop, my previous laptop (zbook g4 with nvidia quadro m1200) had exact same issue. I also disabled it to prevent my laptop from melting.

About the battery live. Ubuntu in general has very poor battery management compared to windows (in my experience and I have been using ubuntu for 2 years now). I use a package called tlp and it quite improved the battery life. Hope this will help you

@ilivss I faced exactly the same issue. I tried resolving it using tlp thermald powertop, but could not find any workaround to reduce overheating when using nvidia cards (I cannot afford to disable it as I need the GPU for my AI related work). I switched to Manjaro and the difference was huge. The battery life issues have also been greatly mitigated
