Keyboard keys (ESC,TAB,é,CAPS,Q,1) stops working intermittently

[Hasanh]

 My keyboard keys on top left side (esc tab é caps q 1)  started to stop working randomly. Then I noticed that when i use them in combination they did other things for instance TAB+1+2 combination made me mute sounds (f6) or when i couldnt use caps lock, the CAPS+Q combination turned caps on and off, TAB+Q+W for f3 etc.

 I've seen other threads on this issue but none of those solutions worked for me. I tried to uninstall the driver on device manager and restart my computer. Cleaned my keyboard thoroughly and tried turning the Action keys mode on BIOS on and off but none of these made a difference. I tried plugging in a usb keyboard and that was working properly but I want to continue using my notebook keys since its way more comfortable than that. Please if anyone had the same issue help me out this is really annoying for me since those are the keys I use the most.

Here's some troubleshooting steps you can try: http://support.hp.com/us-en/document/c03738933

If the laptop keyboard simply does not work, then you will have to plug in an external keyboard and see if you can run the tests using that.

If you are experienced at laptop repairs, you can often replace a keyboard for $25 for a new one and a half-hours work. I have done this on older HP laptops.

But, if you're NOT, there is a serious risk of breaking fragile connectors and cables doing this -- so I do not recommend it.

Instead, I would recommend you hunting down a local laptop repair place to have THEM replace the keyboard. Sometimes, on some models, you have to replace the entire top surface of the laptop, not just the keyboard. So you should get an estimate of what is involved before you have the work done.
