I have a few of these HP 840 G6 laptops that i'd like to fix up. They all have this clickpad issue not just in windows but also in the bios too. The clickpad randomly stops/freezes and you have to take your finger off and put it back on to get it working again. It seems like it's either a hardware or firmware issue with the clickpad. Just wondering if anyone else had this problem with a similar model. Thanks.
