Hi @aka17,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to assist you.

I see that you are facing multiple issues with your Laptop.

Follow the below steps to fix the issue.

-Perform a power drain on your PC.

1) Unplug the power cord from the PC & wall.

2) Disconnect the power cable from the AC adapter if it is a detachable part and keep it aside.

3) Press and hold the power button down for 15 seconds and release the power button, wait for about 30 seconds.

4) Plug the power cord back into the AC adapter, then connect it to the wall and to the charging port on your PC.

5) Power on the PC and check if it boots into Windows now.

-Update the BIOS for your PC by clicking on the link.

Make sure you keep only the charger plugged in while updating the BIOS for your PC.

Click on the + sign next to BIOS and then download the file.

Open the file and follow the on-screen instructions to complete the update.

-Install all the pending updates for the Windows operating system following the below steps.

Go to Start > Settings > Update & Security > Windows Update and select Check for updates. If the upgrade is available for your device and you want to proceed, download and install it.

Hi,

I have same problem as you. I disabled VT-d in BIOS and temporarily problem fixed but HP engineers need to update BIOS anyways.

@IRWIN6 can you send this message to HP engineers ?
