Hello,
The technician was here yesterday and has replaced the parts. So far:
The temperatures are sort of better now, laptop is finally idling at around 50-75 degrees during the basic browser work. During heavy load it will still go to 106-109°C, but at least it's doing something.
I have not encountered BSODs yet, but I guess it is too soon to call it fixed, we will see.
WHEA and ACPI Errors of the are still present after each reboot.
The right front side of the palmrest, the area around the fingerprint reader, now depresses with a click each time I rest my hand on it. It is annoying.
The problem with the throttle state lock is still present, which is very serious as it limits the machine very much. It is mostly present when CPU and GPU are both loaded simultaneously, like in games. After 10-15 minutes the laptop enters sort of a throttle state, where it locks CPU to 20-25W of power with very low clock, and does not come back, the only solution is to disconnect and reconnect the charger. This happens regardless if the laptop is connected to the main charger, or to the docking station. Having to do this several times per hour is simply annoying and unbearable for such a machine, without even considering the impact it has on the durability of the USB-C connector. It clearly looks like a platform problem.
I'll raise you a question - what do we do now? Because I am getting really tired of this machine.
