Windows 11 runs slowly even when using Safe Mode, despite formatting, a fresh installation, and updates.

As recommended on that page, I went to the registry path Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\intelppm and adjusted the "Start" value to 4, then restarted the laptop. Now the CPU speed reached the base speed of 2.11 Hz, although it never actually reached that frequency. The machine has an i5-10210U processor with the following specifications:
Max Turbo Frequency 4.20 GHz
Processor Base Frequency 1.60 GHz
Configurable TDP-up Base Frequency 2.10 GHz
Configurable TDP-down Base Frequency 800 MHz
According to Intel's processor documentation. I believe the turbo boost feature is turned off. I reviewed the BIOS, but it appears to be extremely basic and doesn’t mention anything about turbo boosting. This issue was also covered in a video and an article. I’m unable to verify if turbo boost is even active. I installed several versions of Intel XTU, but they keep reporting as unsupported after some point during installation (I’m using Windows 11 24H2). I also attempted to adjust ThrottleStop to see if I could enable turbo boosting, but it didn’t help.
Now I’m looking for possible solutions and would appreciate any advice.
(Note: I’m aware that many Android manufacturers have lowered mobile CPU speeds over time to encourage new purchases. Companies like Samsung, Apple, and HTC have faced fines from the EU for similar practices. Are they doing the same with laptops?!)
Check if switching the plugged-in power to 100% works

This isn't the situation here.
Recent Windows installations didn't fix the issue, so we're facing faulty hardware. Consider replacing the SSD, though I think the problem might lie with the motherboard (since most components are integrated there).
Check if the device is still using its original thermal paste or pads; they may need replacement. Also, look for debris or blockages in the fans.
I reviewed the whole discussion. In summary, I noticed in Task Manager the CPU speed listed as 0.4 GHz and base speed at 2.11 GHz. The utilization stayed below 20% all the time. After adjusting a registry value, the Task Manager now shows 2.11 GHz, but it doesn’t exceed it when Turbo Boost is active. It seems the laptop should show higher speeds under Turbo Boost, yet it doesn’t. I’m trying to understand how to enable Turbo Boost, as the BIOS doesn’t offer an option.
Your CPU has adjustable thermal design power. It can be restricted to 25W, 15W or 10W.
Therefore, the laptop maker sets the maximum allowed TDP according to the cooling system's capacity.
When the CPU isn't under load, it stays in low power or low frequency mode.
Add some workload, then run a CPU-Z benchmark.
The frequency should reach its peak.
I confirmed the earlier details. If this persists after completing clean installations of Windows, there seems to be an issue likely related to heat or power supply.

It might be worth considering a workaround (registry changes), but adjusting the CPU settings shouldn't be required if the hardware is functioning correctly.
Additionally, the SSD should have been properly detected, which it was expected to do.
Thank you all for your assistance. It seems the adapter could actually be defective, as mentioned in the video by @cruisetung. The adapters or low-quality sensors on the motherboard might send a signal to Windows indicating the adapter is faulty, causing the processor to run at only 10% of its speed. This signal is known as BD PROCHOT. Using ThrottleStop software to disable it resolves the problem. I’m concerned about turning it off completely, as it could damage the motherboard if the adapter is truly bad. There are other signals that also slow down the processor, so disabling this one might not be the only solution. Some comments suggest this, but others say the issue is fixed without affecting clocking. Still, I haven’t tested a new adapter or tried it on another laptop. I don’t have any spare compatible adapter or device.
Another update:
When the machine restarts, it functions briefly but then slows down once more. I opened Task Manager and noticed that initially core frequencies aren’t limited (can reach up to 4 GHz), but after a short time or even a minute they cap at 0.4 GHz.
Now, when I restart ThrottleStop again, the frequencies lift back up and continue exceeding 4 GHz, even when ThrottleStop is active.
On the next restart, I have to manually repeat this process. Adding ThrottleStop during startup didn’t resolve the issue.
I’ve been testing without a charger or adapter connected, so I’m now suspecting the problem lies elsewhere—likely with the sensor.
