3 e d c Keys not working

[ox171ox]

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

I try boot live from usb and still.

@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.
