Every time I plug my charger in my screen dims

Hp 15 Notebook PC
Microsoft Windows 10 (64-bit)
Each time I plug in my laptop to the power cable when it's turnt on my screen darkens and cannot get the brightness back. I have tried brightening it in settings but it already says 100% when plugged in so do not know what else I can do. Can anyone help me please?

Welcome to HP Forums, this is a great place to get support, find answers and tips, Thank you for posting your query, I'll be more than glad to help you out.


I understand that when you plug in the charger, you are unable to increase the brightness from settings. 
For starters, I would suggest decreasing the brightness bar (Let me know if that makes any changes)


Please follow these steps given below to adjust the display brightness:

Step 1: Using the function keys
Step 2: In Windows
Step 3: In the battery settings
