HP Recommended
HP Pavilion Power - 15-cb004nx.
Microsoft Windows 10 (64-bit)

when i press (e d c) together and press (v ) Key the keyboard print (v f r)

and the same thing aply for other key

for example from this device i'll show you how

when i press (edc)  it prints those >>>> jmu,   k,i  fvr k,i l.o ;/p

when i press (ec)  it prints those >>>>,i .o /p vr zq

so it is not printing any thing when press it alone so it is not working 

sometimes it works but come back again

@ox171ox, Welcome to the HP Support Community!



Let us initiate the keyboard test by following the below steps:


  • Turn off the laptop.
  • Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.
  • On the main menu, click Component Tests.


Figure: Selecting Component Tests from the main menu



  • The Component Tests menu displays. Your Component Tests menu might be different, depending on the components installed on your computer.

  • Keyboard Test - The Keyboard test provides a quick interactive functional test of the keys on the keyboard. A keyboard is required for this test. To run the test, click the Keyboard, and then click Run once.
    The Keyboard Test time is 3 minutes.


If the keyboard test runs and fails then you may reach out to our HP phone support team to explore the available service options for your laptop. 


Hope this helps! Keep me posted.
