[2.0] 505: After "battery discharged" warning all buttons stop working

[GoogleCodeExporter]

PRS-505 / PRS+ 2.0.14beta

What steps will reproduce the problem?
1. Wait until "battery discharged" warning appears.
2. Turn off/on reader (by slider button). 

Now when reader is turned on (and you can see book text) non of the buttons, 
except power slider, are working. "Stop sign" icon appears in status bar every 
time button (any: menu, digits or else) is pressed.

As far as I could find out, this can be resolved be reseting reader.
I'm not sure, but maybe also pressing volume key helps and "unlocks" buttons.

What you're describing is intended behaviour by the Sony software. If the 
battery gets too low, the buttons are disabled to force the user to either shut 
down the reader or charge it.

To other developers: relevant code is in main.xml under LOW_BATTERY_GROUP and 
relevant vars in variableChanged().

This is strange. 
I'm pretty sure that before installing PRS+ reader allowed me to read books 
until second warning, after which reader went into shutdown itself.

If I rember correctly you have to press the Center-Button to to close the 
low-battery warning, then you can continue reading until AutoShutdown.

Using the power-slider will suspend/resume the reader, involving additional 
CPU-load -> thus draining the battery even faster.

Exactly. This is expected behavior.

The problem described in first message is that I cannot continue reading after 
closing warning — all buttons (except power slider) stop working, showing 
"stop sign" icon instead.

Sorry, I must have read the code wrong. Mark, can you take this one?

OK, finally got my 505 to the recharge-warning.

I didn't use the power-slider to put the reader into Standby, because this is 
hardly the recommended procedure, but pressed "Center". BTW the only working 
choice.

After that all buttons are working ok, and the reader will shut off after a 
short period of time.

If any, than this is a Sony-bug, not restoring the recharge-warning-group when 
resuming after standby, but still limiting available buttons to "Center"

If you feel this is a real problem, we can think of re-opening this issue, 
meanwhile I will have it set to "Zombie"
