Defy dead - no white LED glowing

[mdave]

Hello!
I searched the other threads for hours, but I seems my problem isn´t covered.

When I got home today, my defy was off and it was not possible to turn it on.
Battery voltage is 3.8V, seems ok.
Phone wont´t charge when connected to charger or PC.
It does nothing when connected to PC with battery inside.
Without battery, the phone flashes one single time the white led.
When I insert the battery at that time, the windows 'usb-device-connected' sound is played, followed by the disconnect sound 2-3 seconds later.
RDS does not recognize the phone.
Pressing volume + did not change anything.

I am out of ideas now and very thankful for any advice.

Thank You!

David

Hold volume down while inserting the battery. Should say ok to program

Thank you very much vor your reply!
Sadly, that did not work either.
I even got an old harddrive with windows xp on it, but it´s the same - connect sound followed by the disconnect sound.
I can even see the motorola flash device in the device manager for 1 second, but RDS does not care. :-(

Can you charge your batt in another way. What about boot in boot loader or stock recovery.?

Thank you!

Since I cannot turn it on in any mode and it is not recognized by RSD, I don´t see a way to do a recovery. But I will try to charge the battery completely with a lab psu.

If it is connected to wall charger you should he getting direct voltage, I would try pulling the battery out, plug into wall charger and hold power button
for 5 sec.

Ok do this, pull the battery out and plug device into av wall charger, hold power button for 5 sec. A image should appear of a battery with "?" Insert battery at this time and it should give you a reading of 5%

Sounds like you battery completely died and it does not have enough power to boot in order to connect to usb, give it direct voltage, is its not working after that i would be worried

Thank you for your reply!
I connected the phone without the battery to the wall charger. The only thing that happens is that the white led flashes every 2 seconds. Pressing the power button even for a minute makes no difference.
I guess that is no good sign. Probalby time to fill out he warranty form.
Poor litte phone. ;-(

Did you try charging with the lab PSU? What resulted from that?

 

[mdave]

Yes, the battery took the charge as it should.
But it did not help.
I shipped it to the repair center an hour ago and hope whatever happened to the device is covered by warranty.

I would like to thank eveyone here for helping me with my problem!
I will post the result here when the center contacts me next week.

Greetings,
David
