I have done all the updates and running 8.1. Normally when it goes to sleep, pressing the windows capacitive button should wake it up immediately. However usally I have to press it and hold it for a second 2 or 3 times, before it will wake up.
Then other times it fails to wake up at all, even though the button does vibrate to show that it is on. So the button vibrates but the screen remains black. Pressing the on and off button at the top of the tablet also does nothing. When that happens, the only option I have is to do a reset, when involves holding the top button down for 10 seconds and then pressing it twice again, which will bring up the surface loading screen. I have had to do this about 5 times since I first got it, which is annoying.
It has had these problems ever since I got it, but I thought it may just be an updating thing, after a windwos update or something. The battery is also at least half full when this happens. There is nothing in the help documentation about this, although there are other owners who have reported this same problem.
I am not sure if I should return it to the shop, as it isn't performing properly, although I think it is a windows software problem that is causing the waking problem. It is running the windows rt version, so the power settings are just the default ones that came with it
I am used to an ipad2 where pressing the button, it just works. The battery life also hasn't been great compared to the ipad, I am lucky to get a day out of it, when the ipad 2 lasts for 2-3 days with the same amount of use. Anyone got any suggestions. I don't have any probelms with the surface once I am able to get it going.
