Windows 11 run extremely slow on battery

Hello,

I need help with an issue I’m experiencing on Windows 11. The system runs extremely slow on battery, making it practically unusable. However, when plugged in, it runs incredibly smooth.

I’ve tried several solutions, including:

Changing the power plan

Updating the graphics drivers

Setting the system to high performance via both settings and the Intel Graphics Control Panel

Disabling BD PROCHOT

Updating the BIOS

Disabling the dedicated GPU

Despite these attempts, the problem persists.

Additionally, I’ve performed a clean installation of Windows, repaired corrupted files, but nothing seems to resolve the issue.

Interestingly, Windows 10 runs flawlessly, both on battery and when plugged in. But Windows 11 is completely unusable on battery power.

Can anyone suggest further steps or explain why this might be happening? It’s really frustrating. 😢

Here are my laptop specifications:

Lenovo IdeaPad gaming 3

Intel i5 10th Gen H-Series

8GB RAM

238GB SSD

1TB HDD

4GB UHD Graphics

4GB Nvidia GTX 1650

Thank you in advance for your help!

Hello, Techie Universe

Welcome to the Microsoft Community. 

Based on your description, I understand that the issue only occurs when using Windows 11 without connecting to a power source. You have already tried many solutions, including power settings, drivers, BIOS, and even reinstalling the system. This is indeed very frustrating, and you have tried enough solutions that we need to re-examine the issue. According to the specifications you provided, I noticed on the official website that the power driver for this model does not have a version that supports Windows 11, only a version compatible with Windows 10. Given this situation, I recommend further confirming this with Lenovo's after-sales support, as this is indeed a point worth suspecting. 

Best wishes,
