Question My laptop's CPU clock speed stuck at 0,39 GHz while gaming or using it's dedicated GPU

[Orbezz]

I'm using an Acer Aspire 5 A514-53G-50LY laptop with an Intel core i5-1035G1 processor and Nvidia MX350 GPU. when the game first launched there was no sign of slowing down until 1 minute of gameplay the game started to become laggy and when I checked the CPU clock using MSI afterburner the CPU clock dropped to 399 MHz and ThrottleStop showed a power limit at PL 1 in both Core and GPU, see my screenshot below.

I'm at Windows 10 Pro 22H2 build 19045.3803 btw if ur asking. As you can see the CPU temperature is at 65°C so it's currently not thermal throttling but power throttling instead this condition appears both while plug-in and on battery. See these TPL values below.

at the PP0 Turbo Time Limit is set to 0,0010 is this normal for this CPU? What does PP0 do anyway?
I have two culprits in mind about this issue number one is the battery because HWINFO shows a 41,5% wear level but I don't know how accurate is that number, and the second is there's something wrong with the charging IC or CPU and GPU power delivery.

Scouring the internet about similar problems I found no solution whatsoever. Updating BIOS, I'm at the latest BIOS. Disabling BD PROCHOT, this thing gets limited for a reason I don't want to take any risks because I need to use this laptop to write my thesis. Reinstalling Windows, it's the same reason.
I'm all out of ideas, maybe you can help me.

Update to ThrottleStop 9.6

ThrottleStop 9.7 Download

ThrottleStop is a small application designed to monitor for and correct the three main types of CPU throttling that are being used on many lapto

Open the TPL window and check the MMIO Lock box which is near the top right of that window.

Power limit throttling due to bad design is a common problem. Fixing this problem is not going to hurt anything. Do a Google search. Throttling laptops are everywhere.

Leave the PP0 Power Limit alone.

I locked the MMIO as you said and made a log file here but the temperature gets dangerously hot so I have to stop it. 35 °C ambient in here and this Acer laptop's thermal capacity is just like crap. Can I modify the maximum processor state to 99% in the Windows power plan while using MMIO to bring down the temps?

the temperature gets dangerously hot

There is no such thing as dangerously hot. Intel set the thermal throttling temperature to 100°C to protect the CPU from any long term damage. Acer went one step further and lowered this to only 92°C. Your CPU will automatically slow down long before it gets too hot.

the maximum processor state to 99%

This setting is not actually 99%. Setting the max to 99% completely disables Intel Turbo Boost and will leave a 1035G1 running at its base frequency which is only 1.00 GHz. Instead of doing that, check the Speed Shift box in the ThrottleStop TPL window and lower the Speed Shift Max value to however fast you want your CPU to run. This is far more flexible compared to the Windows processor setting.
