Hi@Sunnybie, Welcome to the HP Support Community!
I understand the battery light is blinking when you turn on the computer.
No worries, I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution:
Are you facing this issue after an update on the computer?
Can you please help me with the exact product detail?
Please follow the below troubleshooting steps :
1. Disconnect the AC power adapter cord, remove the battery, and hold the Power button for 30 seconds. This will discharge the notebook's system capacitors.
2. Connect the AC adapter to a working power outlet or surge protector and connect it to the notebook.
3. Press the Power button to turn on the notebook.
Check if the issue is resolved.
