I can only recommend NOT applying this update for now.
Windows 11 user with i7-1280p here.
After the update, as soon as the slightest load is applied, the CPU throttles to 0,4 GHz and stays there. This even survives reboots and makes the whole laptop basically NOT USABLE anymore.
The jet engine starts to bruise soon after the load arrives but its way too late already it seems. The only way to get back to usable CPU speeds is by waiting and letting it cool off.
As you can see in the screenshot, it took me like 2 minutes after a reboot to even make it with this performance level/clock speed.
I did both bios and retimer updates. The problem arrived after the bios update and didn’t go away with the retimer updates (not that this would be expected I’d say but it gives a clear indication on where the issue resides).
I’ll now have to look into downgrading this whole thing again…
Man does it suck to have such a powerful machine which did cost a decent sum of money - I even bought the 2.8k screen - not usable at all and now only lying around most of the time.
Edit: By the way, I tried the PTM thing before the upgrade to the new bios as well. It brought the temperature down a couple degrees but didn’t manage to tame the excessive fan blowing.
