Windows 10: Laptop's cpu gets stuck at 0.4ghz on battery but works fine when plugged in

I have bought my Dell G-15 gaming laptop and year ago. It had work perfectly till now since from a few days it's acting weirdly. It became sluggish occasionally and I had to restart. At first i didn't understand the problem and reinstalled the windows but it didn't fix the issue so i further troubleshooted and found out that the cpu speed was being capped at 0.4 ghz when running on battery.I have tried many methods like disabling Intel Speed Step, updating drivers, updating bios but nothing helped. Sometimes it run fine on battery but mostly gets stuck at 0.4ghz. It works fine when the charger

Games work fine on battery but crash when plugged in

Hello guys

My laptop is a HP (Win 10, Intel i5-6200U, AMD Radeon R5 M330 2GB Graphics, 8Gb RAM)

Since last week I am facing a weird problem where my games (War Thunder, Civ6, GTA5) work fine on battery power but crash after plugging in the charger. (The laptop doesn't crash just the game becomes unresponsive). If I launch them when plugged
in, they crash after a few seconds. Steps i have already taken

1. Updated display drivers
2. Reinstalled display drivers
3. Changed power plan settings
4. Reinstalled Windows 10
5. Reinstalled the games
6. Unplugged all connected device

This is an extremely irritating issue so any assistance would be appreciated

Thanks
