Hello @PROBOOK-640-G3 

 

Sorry to hear that you are having problems ... 

I want to help you.

 

(1) Update BIOS

Why should you install the update ?

Updating the BIOS is recommended as standard maintenance of the computer. It can also help resolve the following issues:

  • An available BIOS update resolves a specific issue or improves computer performance.
  • The current BIOS does not support a hardware component or a Windows upgrade.
  • HP Support recommends installing a specific BIOS update.
