According with some posts that can be read here and here, AMTek has released an unit with the same Bios Version and the same unit version than the eo but with better battery life of around 2 hours (2:15 while browsing the web). If versions numbers are the same that means that probably just some drivers or settings has been updated. Now the main question is why AMTek has not provided this update to TabletKiosk? or does TabletKiosk already has this update and is testing it?
If all this is true (and it seems to me that it's true because the numbers shown are hard to guess) we could have a fix very soon.
