I've tried searching the forum and have found multiple answers. I've tried my best to go through all of them, but so far I'm still not able to power on my 770. I've had the device for about a year and I use the device every day to control my HT system. I had heard about the issues with not being able to turn the device on so I made sure to always leave it turned on and just connect to the charger overnight.

Well, yesterday the wife used it down the other end of the house and left it on, so I guess it just ran out of charge and turned itself off.

When I connect it to the charger, the Nokia logo comes up ok and it goes into its charge cycle and even comes up with battery full if I leave it there. However, if I try to power it on while connected to the charger nothing happens. If I disconnect it from the charger and try to power it on, nothing happens. If I disconnect it from the charger, leave it for 5-10 mins and then try to power it on, nothing happens. If I remove & then replace the battery and try to power it on, nothing happens. If I try to press the button multiple times, nothing happens. If I try holding down the power button, nothing happens.

I've also tried switching to a new battery, allowing it to charge up and then trying (just in case it was a battery issue) - no joy.

Seriously I'm out of options! I'm now thinking it might have been a mistake using this device as my primary controller, but until I sort out what to do, I'm dead in the water.

If there's ANYTHING you can suggest that I might not have tried I'd be very appreciative!

I would try something else too, try plug in the usb cable and running the flash wizard till it gets to that point where it wants to find a device then plug in the usb and then the power while holding the home button.
I don't know if it will do anything but it might get you to a new step and you might get it to stay on after that. I have had the same problem as you before, I left the battery out over night and replaced it in the morning and it came back on.

Sorry? The flash wizard? If I connect the USB cable, the device still has no power so do you mean connecting the usb cable while the device is charging, or have I missed a step here?

install the flash wizard if it is not
>go through the flash wizard till it is looking for the 770
>plug in the USB cable
>plug in the power (while holding the home key)
this will cause the 770 to power up and hopefully go into flash mode instead of charge mode. Once you get the USB icon on the 770 try removing the power, it should stay on.

OK, that sounds like it could be useful, but what is the flash wizard? Is that an app that runs on the PC?

OK, did a bit of searching and that sounds like the Nokia Internet Tablet Software Update Wizard. However, I tried searching on the Nokia site and although they talk about using it, there doesn't appear to be a download link for it.

OK - for others with this problem you won't find a link for download on the US Nokia site, but you will find it here...

OK, finally tried the whole experiment.

The Nokia logo and the USB symbol came up when I held the home key and connected power, I was able to remove the power cable and the unit still stayed on. However, there was no way of getting past the Nokia & USB page at all. Hitting the power key while in this mode did nothing, and about 5-10 seconds after disconnecting the USB cable the 770 shut down again.

If you are not attached to your data on it, try flashing a new OS on the 770 with out the power still plugged in, I know for a fact that after a successful flash it will reboot automatically. But you will loose all your install stuff.

Thanks for your help Eric,

I tried re-flashing it yesterday. As soon as the job was done the 770 turned itself off and that was that. Looks like this sucker is dead.

It may be faulty or stuck power button itself. When you attach charger the device boots 'normally' but in the end it hides the UI from you and just shows charging battery icon. So in fact the device is 99% booted and when you press power button in this state it does the final 1% and shows the desktop to you.

This does not help you much, just wanted to say that the device is not dead but works almost fine except the power button. So if you can return it, you probably should but if not, it may be possible to find workaround and power it up by charger and then force the last 1% via some software modification.

Plugging charger is simply another way to power the device on. The boot sequence then checks boot reason (file /proc/bootreason) anf if it is not 'charger' it boots normally and shows the desktop, otherwise it shows the battery icon.

Hi,

I don't know if it has already been posted in any of the power-on threads but i power on my device (770) by:

pressing the "full-view/minimize button" (left to the zoom buttons), hold the button and press the power on button for some seconds till it goes on.
