well, actually it's a bit of a larger issue. you can read more about this project here: (

Basically, the batteries run down, visitors get an error message, wifi gets disabled and the device becomes useless. Then the device gets returned to our staff who have to kill a kiosk client, reenable the wifi, relaunch the client and hand it back out. I'm sure you can imagine, if you had to do this dozens of times a day, this could get pretty annoying.
To top it off, visitors are seeing a message that I would rather supress. It would be better if the wifi worked until the battery was 100% dead -- at least that way it would not be confusing for our patrons.
