T54W display remains black after power saving.
Firmware Version: 96.86.188.9 (Dutch via Lydis)
Hardware Version: 96.1.2.0.2.1.2

Via the web interface I set the office hours on my phone in the power saving settings from 8 am to 6 pm. At 6 pm the display of my device goes out as set, but the next day at 8 am only the background lighting switches on and not the display, so there is nothing to see on the display. The display does not light up completely until I press any button.

I have set the Off Hour Idle TimeOut to 1 minute.
For example, if I press a button at 7:30 am, the display will light up completely, 1 minute later the device will go back to power saving. If the office hours start after this action, the screen will light up completely.

it seems that the device goes into sleep mode during the night, but I can't find a setting for this anywhere, or is there something I might be overlooking?

Thanks for the help.

Hi Peter,

Please try below settings:

Code:
features.power_saving.power_led_flash.on_time = 0
features.power_saving.office_hour.monday = 8,18
features.power_saving.office_hour.tuesday = 8,18
features.power_saving.office_hour.wednesday = 8,18
features.power_saving.office_hour.thursday = 8,18
features.power_saving.office_hour.friday = 8,18
features.power_saving.office_hour.saturday = 7,7
features.power_saving.office_hour.sunday = 7,7
features.power_saving.office_hour.idle_timeout = 480
features.power_saving.off_hour.idle_timeout = 5
features.power_saving.user_input_ext.idle_timeout = 5

Kind regards,
Frank.

hi

I imported the specified settings after changing the hours for Saturday to 8.15. I'll know more tomorrow morning at 8 am. I will post the result here.

Thanks for the help.

Unfortunately, the settings did not solve the problem. The backlight turns on but the screen remains black.

I think this is due to the built-in screen saver.
If the phone is not used for a certain period of time, the screen saver kicks in... in this case at night.
The screen saver is only deactivated by an incoming call, BLF status change, or you press a key.

Kind regards,
Frank.

now that you write about the screen saver I've also started thinking again, and this could indeed be the issue. via the web interface I can set the waiting time to max 12h. but via the CFG file I have now set it to 15h. I have now temporarily set the office hours for Saturday to 8.18 and Sunday to 8.12. I will know more tomorrow morning at 8 am. I'll keep you informed.

RE: T54W display remains black after power saving.
Yesterday morning I was unable to take the test. today I was able to do that. It was indeed the built-in screen saver that activated after 12h waiting time. I set the waiting time via the CFG configuration to 23h (82800sec.) and today at 8am the screen lit up completely.

Problem solved, thanks for the help.
