Windows 10: malfunctioning of laptop keyboard

After installing drivers in my Compaq cq58, some keys on the keyboard are not responding. I tried uninstalling the new driver, the problem worsens. What could be the possible reason and solution to this.

Keyboard Malfunction

We appreciate the information you provided. This issue might be caused by a mismatched driver for your keyboard or pointing device. We suggest to Roll Back the driver by following the below steps:

• Press Windows Key + X, and click Device Manager.
  
• Expand the Keyboards category, right-click the keyboard device, and select
  Properties.
• Under the Driver tab, click Roll Back Driver. This will restore your old driver.
  
• Restart your PC.

If you don’t want to roll back the driver you can try disabling the pointing device by:

• Right side of task bar
  
• Click the pointing device symbol (looks like a laptop mouse)
• Right click
  
• Then click on Disable

Note: You might need to do it every time you power your device.

Should you have further questions please let us know.

 

Specific Keyboard Keys Malfunctioning

My keyboard keys have recently been malfunctioning. Sometimes, the keys do not register at all, and sometimes, it as to be pressed and held with force to register. Only a few select keys are effected, namely the: right arrow key, \, e, g, h, and 8 and 9 on the numerical keypad.

The keyboard was the factory keyboard included with my Asus X751LD laptop.

This started after I used a Java application. It is very unlikely to be a hardware issue, as the laptop was never moved or subjected to drops. Another possible factor is I have used Autosofted Keyboard Presser.

The keys function, although with lag, after startup, but stop working within a few seconds.

I have tried the following to no avail:

• Restarting
  
• Restarting in Safe Mode
  
• Updating keyboard drivers in Device Manager
  
• Updating Java
  

These sites did not help:

• Laptop keyboard occasionally, partially not responsive
  
• why Thinkpad T410s intermittent keyboard death?
  
• Occasionally Unresponsive Keyboard and Mouse
  

Does anyone know how to fix this?

(Was a pain typing this, makes me understand just how much I use the e key)

Edit:

I tested the keyboard with a Linux live CD. First time I booted, the keys will not registrar in a notepad app unless I repetitively press them around 20 times. I rebooted into Linux again, this time the keyboard worked OK, but missed keystrokes occasionally. In both situations it was the same keys as described above that were malfunctioning.

After rebooting into Windows, the keyboard functioned like the 2nd situation above (occasional missed strokes) for around 5min. Then no amount of pressing on the malfunctioning keys could make it register.
