Model#- 15-ac134ds laptop will turn on but screen is black. Tried removing the battery and holding down power button for 15 seconds but didn't help. There are no beeps and no flashing lights.  Thanks for your help.

Hi @Bteresa

Welcome to the HP Support Community. 

Step 1: Remove discs and devices

Before troubleshooting startup issues, remove or disconnect all discs and devices from the computer.

1. Turn off the computer.

2. Remove any discs and USB devices.

3. Remove memory cards from the card reader slot.

4. Disconnect all non-essential devices such as printers, scanners, external hard drives.

5. Leave only the mouse, keyboard, and monitor connected.

After you have removed all discs and devices, turn on the computer.

• If the computer starts, reconnect devices one at a time, to determine which disc or device is causing the problem. If the issue is solved, troubleshooting is complete.

• If the computer still does not start and exhibits the same problem, press and hold the Power button to turn off the computer. Do not connect anything, and then continue troubleshooting.

Step 2: Perform a hard reset

Step 3: Run hardware diagnostic tests

Step 4: Refresh or reset your PC
