Librem 5, hotspot and temperature

[FranklyFlawless]

@veleno

Do you think is there a way to set a max limit temperature in some way (settings) or maybe there will be a fix by Purism in next updates (Crimson)?

It is possible to create/modify trips/triggers for CPU/GPU thermal throttling:

@dos

The CPU is set to start thermal throttling at 50°C - first by limiting the frequency to 1.0GHz, and then starting at 60°C by idle injection. Additionally, the GPU gets throttled at 65°C as well. The critical temperature at which the SoC is forcibly shut down is 90°C (I have hit that in the past on devkit and some early batches when compiling some big stuff, but so far never on Dogwood or Evergreen). These values are set in the device tree: https://source.puri.sm/Librem5/linux/-/blob/pureos/byzantium/arch/arm64/boot/dts/freescale/imx8mq.dtsi#L285

Thinking about your situation in more detail, here are a few ideas you can consider to improve it:

1. Replace your battery with a fresh one in the chance it is defective.

@irvinewade

Should be easy enough to get a spare battery (from Purism) and fault isolate to see whether it makes a difference.

I do have a spare battery. I replaced it and temperatures have dropped

2. Remove the bumper case.

@dos

Oh yeah, I’d definitely not use a bumper case when the phone’s docked. It’s exactly the opposite of what I was suggesting above with the fan

3. Backup any important files/folders, then reflash the Librem 5.

@veleno

ok! found that system process is locked on 100% and RAM and Swap 99,9%
L5 hot and unresponsive (I tried to open terminal and digit: sudo kill -9 (system pid)) to see what would happened but L5 totally unresponsive! I had to switch off it forcing pressing power button.
