How to turn off 770 screen while charging?

[pragnanzer]

Does anyone know how to turn off 770 screen while the device is being charged? There is a small icon with the label "charging" in the center of the white screen. Only when I unplug the device from the charger will the screen be turned off. I have only used the device for 2 hours so far so please forgive my ignorance.

just leave it turned on while charging the display will go to sleep

If you put the cover back over the screen it turns off.

[pragnanzer]

Thanks Greg and Tweak for advice.

Greg's solution will allow the screen be turned off but the device actually remains on (the screen turns on immediately upon touching the screen).

Tweak's solution is interesting because it implies that the cover has an electrical function. I though Tweak was joking but actually what he wrote is true. When the device is turned off, the screen will remain on during charging. Somehow putting the cover back over the screen actually turns off the screen (not just hiding the screen). There are some metallic lining on both sides of the cover that somehow closes a circuit that in turn turns off the screen.

You are correct, there is a magnetic sensor that turns the screen off/on.

So that was it! I have looked and looked to try to find the hidden switch and have so far come up with nothing. Magnetic, indeed! It is a very slick device.

I have the same <problem> like pragnanzer, the display backlight isn't automatically switched off while charging when the device is powered off. Nokia careline told me the same like you said, that it sould be turned off automatically after a few seconds, but it doesn't. Sliding the cover over the device, Nokia said, will turn the display off, like others in this thread experienced. I will also try this.

My question:
Did anyone really see that the Nokia 770 turns the backlight off automatically while charging in powered off mode (so that my and pragnanzer's device is not working properly)?

Nope. Uncovered, the screen stays on at a low level /whenever/ it's being charged.

HTH,

The screen has *always* been on for me while charging, and it seems full brightness too. I've never bothered to slide the cover on. How would I then see "Battery Full"?

[mwohlgemuth]

Thanks for the fast info!

I guess then, Nokia careline is simply wrong by saying that the display should automatically turn off while charging in power-off mode after a few seconds. Also, no good idea giving users such info, as they may go to a service partner requesting a repair while just wasting time.

LVTT:

I think I am correct in stating that while charging, the 770 should be considered almost fully on. Go time a boot. Then time how long until you get Charging from an off state. Almost the same.

My Nokia 770 turned the backlight off automatically while last charging. It was the second charging since I got it. While the first charging the backlight was on. I have no idea why it is so. I had changed the turn-off-time to 2 min. but I can't guess this is the reason.

@ desktop:

Mine still does not turn off the backlight while charging. Went to sleep with the screen on, plugged into AC, last night -- and awoke this AM with the screen still on.

I don't understand how some people have their screens turn off. How can you tell when the Battery Full appears? (OK, so that's not an issue with an overnight while you sleep charge; but there have been two occasions where I've impatiently waited for Battery Full to appear!)

[mwohlgemuth]

@ Mike Cane

I think you had that argument before. I would understand what you mean if by turning on the screen (or playing a sound) the device would give a sign that the battery is now fully charged, which is not the case. It just constantly glows for zero reason. If I were interested in the information whether the device charges or not, I would just read the signs displayed on the N770 saying either it is in charging mode or fully charged. The constant backlight is just a function not under the control of the user, that some find useful (like you) while others find it simply useless/annoying (like me). Therefore, from a user perspective an on/off feature would be a good idea. And as Nokia Careline, after asking a technician, said to me that the backlight should turn off automatically, someone at Nokia considered that function and tried to get it under the user's control already. Only, it obviously doesn't work.

@ desktop:

Yes, I understand what you guys want. I have no argument. Just puzzled.

Obviously the 770 was done under the influence of phone design, where the screen is on while charging. 770 Mark II should have a separate LED for charging/full charge, I think.

[Ceklund]

There is a disclaimer in the included 770 manual (and does anyone ever really want to sit around reading some disclaimer?) indicating that to leave the charger plugged in AFTER the device is fully charged WILL injure the battery life.

It makes me wonder if they didn't leave the light on on purpose so you wouldn't try to go to sleep with it plugged in all night, since that would cause damage to the battery life.

It charges back up in like 30 minutes, so there's no need to leave it plugged in, so maybe they did us a favor by leaving the light on?

But yes, you can turn the light off by putting the cover back on. I'm glad I found out about the battery though.... they're $50 to replace, wouldn't want to have to do that often.... heh....

PS: I absolutely LOVE this machine. It's more slick than I expected, and I CAN carry it in my pocket. I can barely use all of the power from the battery in a single day, so I feel most of the complaints are unreasonable, save the one for a larger base DDR than 64 megs. Having a larger swap file built in would have helped a lot.

[Jeffgrado]

I don't understand how a modern electronic device with a lithion battey doesn't know when to stop charging. Even the battery icon will stop when it's full. Maybe that instruction is just a throwback left over from the Nicad days? :)

[c_legaspi]

in my short experiece and feeling:

yeah, i dont like that light being on when charging

one time i might have turned it off wrong and found that the battery was discharge. i had the cover on with the screen on the open side. any one experience this. i thought i had a defective unit or battery. i then charged it with out the cover and so far no problems.

i havent really investigated but how do you know if the screen goes off when the cover is on. are you able to tell

My backlight turns off automatically after a while when charging when turned off or on.

The case is made of metal. When the front of the case touches the screen, a circuit is made and there is a miniscule reduction in the amount of power eminating from the display. The unit is designed to realise by this reduction that the protective case has been slipped on, and thus goes into the wait mode, with screen off and touchscreen disabled.

It's a magnetic switching system. Very cool. Very slick. Nokia gets bookoo points for inventiveness.

So far , all the times that I have had to charge the Nokia 770, the display goes into ' Sleep Mode ' in a few minutes. This happens even without the cover. Like I will see that the battery is low and connect it to the charger. If I look at it after a few minutes the Display is dark. In order to find out if the batterys has fully charged I simply tap the screen once and if it shows me ' Battery Full ' indicator if the battery is fully charged. If this is not the case then it will show ' Charging ' Indication. Depending on this status I simply leave it as it is or disconnect it from the charger. I still charge it ( when required ) even when the Nokia 770 is turned off. Only in such an instance, I would not know if the battery is full.

Essentially when one puts on the cover onto the Nokia 770, it never ever touches the screen. Instead a small ' Notch ' like thingie inside the cover slips gently, but snguly over another ' Notch ' like thingie at the bottom middle area of the Nokia 770. This ' Notch ' like thingie is just below the screen face. This is indeed the so called ' Magnetic Switch ' that turns the Display on and off when the cover is put on the Nokia 770.

:cool: ;) :cool:

when my unit is off and charging, the screen never goes out. when my unit is on and charging, my screen will go into the standby mode. I dont think this unit is meant to turn off when charging. i think people who says that when their unit is off and charging turns off after a while may be confusing it with the stand by mode. am i wrong or should the unit (when off and not on) really turn off when charging
