ESC key and F1 through F12 keys intermittently stop working

[Mpal81]

The top row on my Keyboard starting with the ESC key and F1 through F12 keys intermittently stop working(keys on right side of F12 work). An external keyboard works fine. Any idea what’s causing this?

Welcome to the HP Support Community.

Let's perform this test:

Install the latest version of the HP Hardware diagnostics (UEFI) on your device using this link: Click here for details

http://www8.hp.com/us/en/campaigns/hpsupportassistant/pc-diags.html

Hold the power button for at least five seconds to turn off the computer.

Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

On the HP PC Hardware Diagnostics (UEFI) main menu, click Component Tests.

Click Keyboard Test.

Click Run once, or Loop until error.

While the test is running, the time remaining and test result for each component display on the screen.

If a component fails a test, write down the failure ID (24-digit code) for when you respond back to us.

If the information I've provided was helpful, give us some reinforcement by clicking the Accepted Solution button, that'll help us and others see that we've got the answers!

Thanks!

Have a great day!
