Could not change the backlight delay of LCD display.

Hi,

I need your help to modify the backlight delay of the LCD display (board is based on AT91SAM9263-EK).

I tried changing the values using Properties - Display, but the LCD still turns off after 1 minute.

Please advise.

This delay is according to the settings in registry, which is located at [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\Timeouts]

Dear Raygloria,

I have exactly the same problem, can you tell me how you have work out the problem? I would like to manage the delay using the right time indicated in the control panel that as far as I know is updating the ACTimeout and BatteryTimeout keys in the HKEY_CURRENT_USER\ControlPanel\Backlight entry.
thanks a lot
