@zohaib78 Welcome to HP Community!

I understand that charger lights blocking.

Perform the below steps to resolve this issue: 

Symptoms: Battery power LED blinks, and Caps Lock/Num Lock off 

Possible failure: AC adapter not connected or failure / Battery low charge or failure 

If the battery power LED and the LEDs near the Num Lock and Caps Lock keys do not glow when the computer is disconnected from the AC adapter, then the battery has a very low charge or is not charged at all. Try the following two procedures for diagnosing the power issue: 

Charge the battery: 

Use the following steps to charge the battery. 

1. Connect the AC power adapter, and verify that the battery power LED glows. 

2. Allow the battery to charge for 15 - 30 minutes. 

3. Attempt to start the computer.
