Certain keys on my keyboard do not function sometimes.

[kendall99]

Some keys on my laptop keyboard only work sometimes. I have to keep pressing them over and over until it finally displays the key that I have pressed. I have already deleted and updated all the keyboard drivers as well as Windows 10.  I have also tried  the hardware diagnosis and the keys were working normally, but as soon as I sign into any user, the keys go back to not functioning. I'm not sure what else to do or how to fix this issue.

@kendall99 Did you check if the issue occurs on an external keyboard?

While you respond to that, here's what you need to do:

I recommend you attempt the below steps to identify the cause of the failure and resolve it accordingly:

• Try changing the keyboard layout/language and check if it works: Click here for steps.
• Clean the keyboard with compressed air (blow compressed air in the gaps between keys). This removes some lint and dust. 
• Shut down the laptop, remove the battery and cable for a moment, press and hold the start button for 60 seconds
• Replace the battery, restart the notebook,
• if the issue persists, perform an interactive hardware test on the keyboard using the steps mentioned on this link: Click here (look under "Running Component Tests > Keyboard test").
