HP Pavilion shuts down randomly by itself

[ArubaBob]

My HP Pavilion 15 Notebook PC has started to switch itself off randomly. I have HP Cool sense on. I have tried running the various diagnostics from the HP Support  assistant but that hasn't helped.

Welcome to HP Support Community

I would like to help

Please ensure you update the BIOS or Chipset

I suggest you download and run the HP Support Assistant from this Link: https://www8.hp.com/us/en/campaigns/hpsupportassistant/hpsupport.html?jumpid=va_r602_us/en/any/psg/p...

HPSA will automatically search for all the latest drivers for your Notebook

1. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.

   

2. Click Check for updates and messages to scan for new updates.

   

3. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.

4. Click the update name for a description, version number, and file size.

5. Select the box next to any updates you want to install, and then click Download and install.

Also ensure Windows is up to date.

Select the Start  button, and then go to Settings  > Update & security  > Windows Update , and select Check for updates. If Windows Update says your device is up to date, you have all the updates that are currently available

If the issue persists run an Extensive Test on the Notebook and let me know if it shuts down during the Test

- Shut down the Notebook completely

- Turn it back on, then tap the Esc key repeatedly until the Startup menu screen is displayed.

- Press F2 to select System Diagnostics.

- Click System Tests, then click Extensive Test.

Keep me posted how it goes

Thank you and have a wonderful day 😊

Unfortunately, none of that worked. I took the laptop to a professional who diagnosed that there was a motherboard fault. This was going to be too costly to repair. I am now looking for a new Laptop.
