Fixed – HP Laptop Touch Buttons Stop Working

Trouble:

My HP Pavilion laptop’s touch buttons stopped working a few days back. I re-started the laptop and it started working. After a few days, the touch buttons again stopped working. This time, even after restart, they refused to work.

On searching the internet forums I realized that this a common problem with many HP Pavilion laptops of DV4 and DV5 series which have touch buttons. In this post I will share the way in which I solved the problem of Quicktouch touch buttons not working on HP laptop. This solution may work for other brands as well.

Fix:

There are three things you need to ensure to make the touch buttons work properly, they are:

Touch Buttons Software Is Running

To check whether touch buttons software is running, open the task manager (pressing Ctrl + Shift +Ecs key together). On task manager, check the process named hpkbdapp.exe running on HP laptops. For other brands, look for similar kind of Softwares running at the moment. See the example below:

Look For Updated Drivers Online

Go to Laptop manufacturer’s website to look for updated software drivers. In my case, I looked for updated Drivers of touch buttons online at hp.com . Update the drivers to the latest version.

Restart the laptop and hope it works.

When Nothing Works, This Method Works

This is a strange sounding solution but is tested by me and worked well for me and for many others. I got to know this method from this forum (thanks to Notebookreview.com forum). The method suggests to shutdown the laptop, remove the battery and adaptor. Press power button for 45 seconds with battery removed. Leave the laptop without batter for few minutes, and then insert the battery again and it will start working.I did try this solution and it worked for me.

Many of you might be curious to know why did this solution work? Well, the answer is not that complicated either. The touch buttons work on some sort of sensing of skin touching the surface, and must involve some electric charges to accumulate on the surface of the touch buttons. On removing battery and power, and pressing power button while battery removed, you have discharged the surface of eclectic charge imbalances and it starts working. It will be too much science to discuss beyond this point.
