- Remove the battery (if removable) and hold the power button for 30 seconds. Reconnect the battery and try powering on.
- For non-removable batteries, press and hold the power button for 60 seconds.
- Inspect the motherboard: Look for burnt components, swollen capacitors, or loose connections (requires opening the laptop).
2. Display Not Working (Black/Blank Screen)
Symptoms: The Laptop powers on, but the screen remains black.
Solutions:
- Test the display:
- Connect an external monitor. If it works, the issue may be with the laptop’s screen or internal display cable.
- Check RAM modules:
- Reseat or replace RAM sticks (corrupted RAM can cause display failures).
- Reset BIOS settings:
- Remove the CMOS battery for 5 minutes to reset BIOS (refer to HP’s manual for location).
3. Overheating & Random Shutdowns
