My touchpad will not remember anything it has learned since last Thursday. Every time I power it down, everything - downloaded apps, downloaded files, changed settings, etc. that have happened since it wasa last powered on are all missing after I power it back up. This has happened multiple time. Things are fine while it's powered up - I ccan install and play a game (sliced), but if I power it down and back up - it's all gone. Any ideas?
