I have a brand new ProBook 430 G2 (SKU # G6W35EA#ABB) with Windows 8.1, fully updated. I find that every 10-15 minutes, the left button on the trackpad becomes unresponsive. The trackpad still moves the mouse pointer and the right button continues to work, but the left button does not react. This lasts for several minutes, perhaps 3-4. Then the left button resumes working as if nothing had happened. Since the button resumes working, I suspect it is more likely to be a software issue with the driver or Windows 8.1.
I have Synaptics TouchPad driver version 18.1.8.1, the current version of the driver.
I have Windows 8.1 version 6.3.9600.
I have Bios version HP M74 version 1.03 (07/07/2014)
Anyone have any ideas?
