Comment 14 for bug 1987829

I can confirm that the overheating issue happens on a LG Gram 14 14ZB90Q with an i7 1260P whenever I plug it into its power adapter. Also when rebooting I get "Failed to start Detect the available GPUs and deal with any system changes." message and have to power off before powering it back on to boot it correctly. I also get the spam of ACPI messages "ACPI Error: Aborting method \_SB.PC00.LPCB.LGEC.SEN2._TMP"

If I power it off, and leave it off for a bit, then power up just on battery the temps seem normal. But when plugging into the power adapter, it will act normal for a couple minutes, then suddenly it gets really hot, even though cpu usage is minimal, and clock speeds are low. Each core goes up to the limit around 90C.

Edit:
Forgot to mention I'm on Ubuntu 22.04 LTS, and this happens whether I user kernel 5.15.0-58 or 5.19.0-28
