Guys,
I'm somewhat new to this CPU "tinkering"/troubleshooting and ThrottleStop.
Just bought a Lenovo P15s for the relative efficient CPU and GPU (Nvidia T500), and expected it to be major upgrade from my pervious system. In theory, yes. But in practical terms, it runs terrible.
Out of the blue it will throttle as low as 0,39GHz. this can happen while surfing, and it also happens during CPU/GPU intensive work, like Video editing. Interesting is, that sometimes it will work fine for hours, and at other times it will just not.
A bit research brought me to ThrottleStop. Currently I "only" see PL1-errors (in the attached log). If I read ThrottleStop right, power is currently limited to 6.7W for the CPU (or even CPU/GPU combo)?
The log (attached) from a few minutes ago still shows a "whopping" 8W.
I've seen thermal and PL2 warnings before, but with the current power consumption limited, I currently can't get any heat ;-)
Talked to Lenovo, they suggested BIOS-Update or a defective device. Bios update done. Nothing changed. I still can return this unit, and I might have to. But as a side note, for using outside, I love the 600nits on this screen.
I asked Lenovo, if this is a general problem, but was told that issues with such power limiting are unknown, and the device might just be defective. After some research which led me here, I wonder if this was the truth. Can send it back, order a new one, but if this throtteling issue is "by (bad) design", then I have to shop elsewhere...
Any ideas what is going on here?
What to do from here?
And an off-topic-question:
Even though the unit realizes it's on AC power, could this be a power supply issue? This unit only has USB-PD. Is there a way to find out what voltage is provided by the power supply? Could such a throttle happen, if the power supply only sends 10W, and the drivers want to prevent the battery from discharging, even if the battery is full?
