Laptop runs HOT after 12.10 upgrade!
- by dinkelk
I was running 12.04 for 6 months, my laptop ran almost silently and cool enough to hold on my lap. I updated to 12.10 and now my computer gets too hot to hold on my lap and the fan is constantly running on full blast. This is the output of sensors:
acpitz-virtual-0
Adapter: Virtual device
temp1: +84.0°C (crit = +99.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +84.0°C (high = +86.0°C, crit = +100.0°C)
Core 0: +74.0°C (high = +86.0°C, crit = +100.0°C)
Core 1: +72.0°C (high = +86.0°C, crit = +100.0°C)
Core 2: +75.0°C (high = +86.0°C, crit = +100.0°C)
Core 3: +84.0°C (high = +86.0°C, crit = +100.0°C)
radeon-pci-0100
Adapter: PCI adapter
temp1: +76.0°C
I have an HP Pavilion dv6, i7, amd radeon graphics. Please let me know if you need additional information.
What could be different between the two Ubuntu additions that caused such a drastic change?
Edit 1:
Per @Paul's suggestion, I ran htop to try to narrow down the problem. Here is the result!
This is about 10 minutes after boot-up, htop, yakuake, and a chrome page with 1 tab opened to this question are all that I have manually opened. The most taxing program to the CPU is htop itself. I think that the problem must lie elsewhere; my temps are already up to ~65C for the CPU and ~69C for the GPU, with nearly 0% CPU usage.
