Battery life with exam mode

[cyrille de brébisson]

Hello,

normally, 15 minutes timeout means 15 minutes time out and this seems to work fairy well.

Doing a full reset While in exam mode will change the timeout to 8h (the max duration of an exam). This is due to the fact that the full reset will erase the clock, so there is no way for the system to know 'when' is now, so it defaults to 8h.

Normally, no reset system will exit exam mode (by design). However, USB connection to a PC should kill the 'basic' exam mode (green LED) and timeout will kill any other exam mode (<8h).

What baffles me is that people manage to place the calc in exam mode 'by accident'. It takes a number of keystrokes to start exam mode so it seems weired... but anyhow, it happends!
