Pavilion laptop won't start even after hard reboot

HP Recommended
Pavilion dv6

My laptop will not restart. Have tried the hard reboot in the past but this time it is not working. Power light is on and red lights on (speaker symbol and wifi) but screen remains black. Fan is running but nothing happens.  Recently when working the fan was running noisily and laptop was hot. It didn't go into hibernation mode when closed lid. What can I do to restart it?

Hi! @Garden2018, Thanks for stopping by the HP Support Forums!


I understand you see a black screen even after performing a hard reboot on your PC.


I understand your situation and concern but not to worry I'll try to help you out.


Did you make any software or hardware changes on your PC?


Have you tried checking with a different battery or adapter?


Do you see any blinking lights or lights on your PC?


Does the issue persist when you are at BIOS page?


Do you see a black screen with blinking cursor on your PC?


Have you tried checking with an external monitor does the issue persist?


Please share the product number of your PC to assist you better.


I appriciate your efforts for trying out the steps before reaching out to us.


To perform a power reset on a laptop with a removable battery:

  1. Turn off the computer.

  2. Remove the computer from any port replicator or docking station.

  3. Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.

  4. Unplug the AC adapter from the computer.

  5. Remove the battery from the battery compartment.

  6. With the battery and power cord unplugged, press and hold the Power button for about 15 seconds to drain any residual electrical charge from the capacitors.

  7. Insert the battery and plug the AC adapter back into the laptop, but do not connect any of the peripheral devices.

  8. Press the Power button to turn on the computer.

    The computer starts normally or a startup menu opens.


    If your computer does not start after pressing the Power button, then a power reset did not resolve the startup issue. See Additional resources for further troubleshooting steps.

  9. If a startup menu opens, use the arrow keys to select Start Windows Normally, and then press the Enter key.

  10. After Windows opens, reconnect each peripheral device that was disconnected, one device at a time, until all devices are reconnected.

    Your laptop has been reset. After a power reset, it is a good idea to run Windows Update and HP Support Assistant to update all device drivers. See Updating Drivers and Software with Windows Update (Windows 10, 😎 and Using HP Support Assistant (Windows 10, 8, 7) for more information.


Try updating the BIOS and graphics drivers on your PC using HP support assistant.


Refer this article to know more information about using the HP support assistant.


Try restoring the BIOS to default and check if it helps.

  1. Turn off the computer and wait five seconds.
  2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
  3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
  4. Press F10 to Save and Exit.
  5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
  6. Follow the prompts to restart your computer.

Try the steps recommended below.


1. Use Windows shortcut keys Win + PauseBreak to open the System window.

2. Select Advanced system settings from the left column and the System Properties will pop up.

3. Choose Advanced tab and click on the button Settings in the Startup and Recovery section.

4. Disable Automatically restart under System Failure, and then click OK.


1. Right-click on the Start menu and select Power Options. You can also access to this by right click on the battery icon in the taskbar if you are using a laptop.

2. Click on the Change plan settings beside the current plan the PC is using.

3. Click on the Change advanced power settings.

4. Navigate to and expand the Processor power management.

5. Expand the Minimum processor state and set the values lower than 100%. And then click OK.

6. Modify the Put the computer to sleep setting when using power or battery. Set the time value between 1 minute and 5 hours.

7. Save the changes and reboot.


Also, try running a system diagnostics test on your PC and check if the hardware components on your PC are working fine.
