I didn't want to send my laptop off but did after similar experiences described here, incompetant techs that don't believe this is a hardware issue or simply aren't informed by the company the work for that THIS IS AN ISSUE.
I spoke with several people that have terrible dialect/accents from presumably India. It also seems as if they follow a prompt based system, as I'd tell them what was going on and then there would be this wait as if they were waiting for a computer to tell them what next to try - TERRIBLE.
After several calls, and even having my service order(depot return) cancelled by them, why not sure??
Received the box, sent it in(took five days from New Mexico to Houston Depot) - i placed videos on desktop of ghost touch issues plus referenced this forum. Laptop work was completed in less than a day, boxed up and send fedex back to me to make it a week (7 days) turnaround.
Screen was replaced and have not had any issues now going on three weeks, so I would say send it in and document what is going on take a video with cell phone and place on desktop.
Hopefully i have no further issues, but laptop is now fixed, thankfully.
