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
