Comment 18 for bug 1987829

@kaihengfeng
I gave latest mainline a try on my Fedora, installed through copr according to this doc: https://fedoraproject.org/wiki/Kernel_Vanilla_Repositories
It's kernel 6.3 instead of 6.2, but I would assume it contains changes from 6.2.
No luck, still same symptoms.

Also the issue is now occurring even when the laptop's battery is 100% charged as it is currently.
On a side note, a Thunderbolt docking station from Dell, which also charges the laptop, shows the exact same symptoms as the embedded charger.

All the best.
