I tried searching the old posts for this problem but didn’t see one so I apologize if this has been mentioned in the past. I have inherited a Q702 and the touchscreen intermittently works. When I power it up off the dock, the touchscreen works for a bit. Then I have to connect it to the dock for internet and connection to my work network. The touchscreen then quits working and only works off and on during the day. There’s got to be a fix that I haven’t found. I updated the driver but it still does this. Also I am running Windows 7 and our IT doesn’t have an answer for the fix. Thanks for your assistance.
