Problem with 4 keys, Up Arrow, Num Lock, key pad 1 and key pad 7

[EagleGreek]

I having problems with my GK100F mechanical keyboard which I bought 3 months ago. The problem is with specifically four keys, the Up Arrow, Num Lock, key pad 1 and key pad 7.

• The Up Arrow outputs the letter "a" before moving the cursor up. 
• The Num Lock outputs the "=" sign before toggling the Num Lock on/off.
• The key pad "1" outputs the number "1" and brings up the context menu.
• The key pad 7 outputs the single quote mark and then  the number "7" itself.

Is there a way to resolve this?

Hi@EagleGreek, Welcome to the HP Support Community!

I understand you have keyboard issues with your PC.

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

Did you make any software or hardware changes on your PC?

Have you tried checking with an external keyboard does the issue persist?

As you mentioned keys on the keyboard stops functioning correctly.

Try few steps recommended below.

Turn off the computer and then restart it.
Press the Esc key repeatedly to see if a startup menu opens.
If a setup menu does not open, the integrated keyboard hardware is not working. The integrated keyboard in the notebook should be serviced or replaced. To continue using the notebook, connect a USB-wired keyboard to a USB port and restart the computer.
If a setup menu opens, use the arrow keys to navigate the menus. If these keys are working in the startup menu, but then fail when Windows loads, the problems might be related to the keyboard software.
Restart the computer.
In Device Manager, uninstall and reinstall the keyboard software:
In Windows, search for and open Device Manager.
Click View and select Show Hidden Devices.
Click the arrow next to Keyboards, right-click the keyboard device name, then select Uninstall to remove the device from Windows.
Continue removing device names in the Keyboards category until all device names have been uninstalled.
Restart the notebook. Right-click Start (), select Shut down or sign out, then select Restart.
Wait for the computer to restart and open Windows.
