Laptop Keyboard Keys not working

I have a hp-1000 notebook and suddenly g, h, apostrophe and backspace keys have stopped working. I know it is a hardware fault either with keyboard strip or motherboard connector. I want to know which wire in the strip ribbon corresponds to which keys in this particular keyboard. Thanks

Hi Rizwan,

Shut down the notebook, unplug the AC Adapter and then remove the battery.  Hold  down the Power button for 30 seconds.  Re-insert the battery and plug in the AC Adapter.

 Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu.  Press f5 to load the defaults ( this is sometimes f9, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter.  Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.

Confirm fault by plugging in a USB keyboard.  If the USB keyboard works OK then most likely the fault lies within your keyboard (or possibly the strip ribbon as you suggest.)  

Also possible (unlikely unless someone has been playing with the laptop) is that the strip ribbon is not seated correctly within the motherboard connector.  You can unfasten the connector and reseat the ribbon and see if that fixes the problem.

Unless you know someone at HP I suspect you won't be able to find which wire supports the keys you talk about.

Note that the problem you describe usually lies within the keyboard.

Replacement keyboards are fairly cheap these days, normally $20 to $50, so that is the way to go.  You may find 2nd user keyboards on ebay for even less.  If you post the precise model number of your laptop, we can help further in finding one.  I don't think there is any way you can repair the keyboard.  As the keys that are faulty are NOT next to each other, it is more likely to be the cable, but these are generally hard-wired to the keyboard itself.  Of course, try dbrunton's excellent advice on reseating it.

I don't believe the advice above in terms of resetting the BIOS will fix this issue, by the way.

These 3 comments cover the solution to fixing the keyboard problem.  They do not cover identifying wire that is causing the problem as that is NOT a practical solution.

The other solution proposed does not seem suitable for this problem.
