What steps will reproduce the problem?
1. Allow the device to go to sleep (Screen Off)
2. Attempt to wake the screen using the power button
3. Screen does not respond (Power LED does)
4. Further pushing of the power button makes the screen blink on just before 
going back to sleep 

What is the expected output? What do you see instead?
Screen should wake when power button is pressed

default OS correctly?
Archos OS works, haven't used previous versions

The problem occurs ONLY if you set the brightness to a very low level.
I went mad for days trying everything.. deep sleep, removing apps, killing apps 
before sleep, etc etc... until I found this:

I had the problem before moving to UD (2.3.26) and after (UD 1.0), but now I 
know the cause and it never occurs anymore. My brother has a 101 as me and 
solved the problem as well.

I don't know if it's an hardware problem, in such a case a workaround could be 
to deny the possibility to reduce the brightness level to the lowest values.

It would be better for the resume code to:

- Save brightness setting
- Set brightness to maximum
- brief delay
- restore brightness setting

This way, any brightness can be set, but on resume the LCD will properly start 
up.

Nice solution.
Another one cound be to save the brightness level, put it at max, and than put 
the device to sleep.
At resume the brightness could be restored to the saved valued.
