I'm having an issue where if I restart the tablet it gets stuck between shutting down and starting up leaving me with a black screen. I usually then have to soft reset it by holding the power button down for 10 seconds after which it starts up as normal. It sometimes does this after a regular shut down or even sometimes after it's just been asleep. I have done several factory resets slowly installing windows updates, programs, everything I can think of to no avail. This is the third tablet (2 replacements) so I'm thinking it's not a hardware issue. Asus don't think it's a known problem and I've trawled the net but I haven't found many others having this issue. Any help or suggestions would be greatly appreciated.
