HP Pavilion laptop keeps turning on at night by itself! Someone helpppp!

[dby9999]

HP Pavilion laptop keeps turning on at night by itself! I have tried downloading software to block window update. I have stopped all wakeup's. Killed wakeup when mouse or keyboard is touched. Tried finding last -wakeup without any success, nothing shows. I have my laptop set to hibernate and approx. every other night my laptop reboots to bios. I have an administrative password set so it nevers loads windows.  I have been trying to figure this out for 5 months without any success. You name it I have tried it. I have completely killed task scheduler - which now shows nothing. Totally disabled windows update, in fact the last one was done in October. Does anyone have any idea what could be causing this your help would greatly be appreaciated.  Thanks

Hey there! @dby9999, Thanks for stopping by the HP Support Forums!

I understand the laptop keeps turning on itself during nights.

Don't worry I'll try to help you out.

Was there any recent windows update on your PC?

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

Excellent description and a great diagnosis done. It is greatly appreciated.

Check if the power button on your laptop is being pressed.

Disable Fast Startup.

Go Control Panel 
Power Options
Choose what the power buttons do 
Change settings that are currently unavailable
uncheck "Turn on fast startup (recommended)"
save changes.
Also, go to advanced power settings -> Sleep -> Allow wake timers and disable it.

Uncheck automatic restart on your PC.

1. Click on Search bar.

2. Then type "System" without the quotes in the search bar and click on it.

3. Click on Advanced system settings.

4. Then click on Advanced tab.

5. Click on Settings under Startup and Recovery. 

6. Uncheck mark on Automatically Restart and click on Ok.

Also, Try the steps recommended below to restore BIOS to default.

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.

Try updating the BIOS and chipset driver on your PC and check if it helps.

You can try updating the drivers on your PC using HP support assistant.

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

If the issue still persists after trying out the steps try the steps recommended below.

In Windows, search for Command Prompt. In the search results, right-click Command Prompt and select Run as administrator. Then click Yes.
In Command Prompt, type sfc /scannow. Make sure to include the space between sfc and the /.
Press Enter and wait while System File Checker scans for corrupted files.
When scanning is complete, the results are displayed on the screen.
If the file checker found and replaced any corrupted files, restart the computer and check the performance.
If the file checker did not find any corrupted files or found corrupted files but could not replace them, go to the next step.
If System File Checker finds corrupted files but cannot replace them, use the Deployment Image Servicing and Management (DISM) tool. DISM checks the corrupted files; then downloads and replaces the files using Windows Update.
In Windows, open a web browser.
   NOTE:
You need to be connected to the Internet to use DISM.
In Windows, search for Command Prompt. In the search results, right-click Command Prompt and select Run as administrator. Then click Yes.
In Command Prompt, type dism.exe /Online /Cleanup-image /Restorehealth. Make sure to include the space before each / in the command line.
Press Enter and wait while DISM works. This might take several minutes.
If DISM finds corrupted files, it replaces them using Windows Update. If this occurs, after DISM is finished, restart your computer and see if the performance has improved.

If the issue still persists try running a system diagnostics test on your PC and check if the hardware on your laptop is functioning correctly.

Refer this article to know more information about running system diagnostics on your PC.

Let me know if this works!

Have a great day! 🙂
