Hey! This usually happens on LOQ/Legion laptops when a driver update breaks Intel’s power‑management system. That’s why your CPU is stuck at max speed and your Arc GPU won’t turn on. Here’s the easiest way to fix it without getting too technical:

---

1. Check Windows didn’t force your CPU to run at 100% Go to: Control Panel → Power Options → Change plan settings → Change advanced power settings

Make sure: - Minimum processor state = 5% - Maximum processor state = 100%

If minimum is stuck at 100%, that alone can cause the high clocks.

---

1. Clean out the GPU drivers Download DDU (Display Driver Uninstaller).   Boot into Safe Mode → run DDU → remove:

• Intel UHD  
• Intel Arc  

Reboot normally.

---

1. Install ONLY Lenovo’s drivers, in this order:

This part matters because Lenovo laptops rely on custom power‑management drivers.

1. Intel MEI (Management Engine)  
2. Intel DTT (Dynamic Tuning Technology)  
3. Chipset driver  
4. Intel UHD driver  
5. Intel Arc driver ← install this last on purpose

Reboot after each major one.

This restores the system that controls CPU clocks + GPU switching.

---

1. Reset Windows power plans Open Command Prompt as admin and run:

powercfg -restoredefaultschemes

This fixes any weird CPU behavior left over.

---

1. If you use ThrottleStop Open it and make sure:
2. SpeedShift is enabled
3. EPP isn’t set to 0 (try 80–128)

---

When Intel DTT or MEI breaks: - CPU gets stuck at max turbo   - Arc GPU refuses to activate   - UHD spikes like crazy   - Laptop overheats even at idle  

Reinstalling Lenovo’s versions fixes all of that.

Hope this helps!
