Hi @Huagh 

I understand you are having issues with some right ALT key on your keyboard is not working. Don't worry as I have a few suggestions which should help you resolve this issue.

Perform a Hard reset on the notebook: 

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset". Use the following steps to perform a hard reset on a computer:

If Windows is open, click Start and then Shutdown.

If Windows is not open and the computer has power, press and hold the power button on the computer until the computer shuts off.

With the power off, disconnect the power cord from the back of the computer.

With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.

Reconnect the power cord and turn on the power.

If you have an alternate USB External keyboard, you can try to connect to the computer and check if that works.

If the external keyboard works fine, this clearly indicates a possible failure with the Notebook keyboard.

If the external keyboard doesn't work either, then I would suggest you could try creating a new User account and followed by System restore, 

Follow the steps here to create a local account on your PC: Create a local user or administrator account in Windows - Microsoft Support      

Follow the link for system restore: HP PCs - Using Microsoft System Restore (Windows 10,

Alternatively, you can try to test the keyboard.

Then perform these steps to isolate the issue to being hardware or software related.

• Power down the unit. When you power it back up, immediately tap the F11 key gently several times.
• It takes you to recovery manager. Here please select the option “Troubleshoot”. Then please select “Advanced options “ and  “command prompt”
• Type all the keyboard characters in this black window especially the keys that do not work correctly.
• If F11 does not take you to recovery manager, please keep tapping the “ESC” gently several times the instant you power on the unit. It takes you to the startup menu and you could press F11 from there to go to recovery manager. Please check all the keys in the command prompt black window, especially the keys that don’t work.

If it does not work in the command prompt window the computer certainly has a keyboard hardware issue.

If this solution hit the spot, please come back and click "Accepted Solution" to help others find the answer. And if you'd like to say thanks, select "Yes" on the bottom left of the public post, as that would make our day! 

Take care, and have an amazing day!
