What heat do you mean? From the environment (ambient temperature)? From the device (from operation)? There may be some benefit to looking at the actual thermals i.e. what is the operating temperature of the device?
If from the device, is there a runaway process on the device?
I couldn’t get PureOS mobile to work, would not run updates because of “unmet dependencies”, so I’m running Debian Gnome. PureOS mobile hasn’t been properly updates sense 9/2023.
Just finished running a test with a core temp meter running in the system tray.
For the test, I played AisleRot Solitaire for about 10-15 min.
I’m in Hawaii without AC in the wet season. Ambient temp is about 80ish in my shoe box apartment.
Once internal temp hits about 33C (92F), the touch starts becoming unresponsive and dropping the cards I’m dragging around. I bring up a menu with some difficulty and things “get selected” in the menu. Seems to be something near the center of the screen is selected, every time (maybe slightly up and left of dead center).
Looks like a hardware design issue.
