After quite a few months of having an odd screen image(screen was divided into 4 segments with a scrambled image) my HP Touchpad came back to life. It worked great for about 12 hours then crapped out. Now, nothing. Was this it's last gasp of air before joining those great WebOS devices in the sky? It will not charge, in fact the small charging indicator does not illuminate at all. Has this become a useless doorstop or is there some help for this???
