At first it worked but then a cable came out which I described to tech support to find out it's supposed to be plugged in. I did so and it worked for a few days only to have it not respond with it in the upright position again but it will take a week for the tech to arrive with parts. Tomorrow I hope it will be fixed. I've had to sleep on it horizontally which is difficult considering my height and being handicapped. I hope tomorrow night this will be much better.
