Thinkpad: Is there a solution to this problem before I pee on the laptop?
no, there's an issue where it doesn't allow the computer to run any faster than that. I've run cad software and had it still throttled down to under a gHz
Its possible that the number task manager is showing you isn't accurate. Is the computer actually running worse than normal?
I have a fix for that. You're currently experiencing throttling issues. You can fix that using Throttlestop.
If you put some sort of computational load on the machine, does the clock speed go up? Something like can peg your CPU usage pretty quickly, which should cause the speed to go up. It's not useful to measure that when the machine isn't doing much, since this is an intentional power-saving technology.
When mine does that, I unplug it and plug it back in, and it resets the power settings back to "plugged in" and allows it to run faster again.
when processors get hot, they slow down to try not to burn themselves, usually when the cooling system is not working properly
The laptop does not heat up at all, even the fan does not work because the device is stable on this performance, but I tested the fan and it is fine by the way
It's power limit throttling. As far as I can tell... this range of ThinkPads do this for absolutely no fucking reason at all.
My "fix" was to disable the Nvidia GPU, and to prevent the CPU from going above like 1.8 GHz. Then, it would never get into territory where it thought it needed to Throttle.
The real fix for me was to ditch the whole platform and go to a new AMD-based ThinkPad.
Maybe has more specific tips, if you want to pursue actually fixing the issue on your laptop. Something about flashing an alternative firmware to allow you to unlock the throttling settings.
I think that the problem with using a non-original charger for a period not exceeding a week is not a problem with the graphics card
