dear squeeze ur MDA pins with small flat screw driver or some type of needles..i hope this will work...

you might have killed the charger 4rom charging 2 much it can only charge soooo much

if you insurance on your phone I recommend using it, I had a MDA for a couple years and had about every problem in the book, but not that one. It sounds like you've done everything possible, the only other thing i could think of is a hard-reset. Anything beyond that would tinkering with the internal hardware.

I think you can get a MDA pretty cheap on ebay these days

Make sure you have an original OEM charger for the MDA. Many of the knock off chargers don't provide the right amperage for the device. What happens is that since the phone is completely dead, it can't regulate how many amps the battery should get during the charge and an incorrect charge current won't charge the battery. I'm guessing that someone sold you a Motorola RAZR charger or another knockoff made for the RAZR. This might charge your phone when the battery is working, but not when it's DEAD. Also you won't have luck plugging it into a computer USB cable because, again, the phone can't tell the computer what charge to send and most computers only produce <0.5 amps in the USB port.

Get a charger that states it is an OEM (original eqipment manufacturer) device or one that is specifically designed for the MDA (or Cingular 8125). eBay is full of them.

Bad charger (probably won't work for a dead battery)

Good Charger (correct amperage and designated for the MDA)

mine also did it and finally nothing on even I thought battery died I bought a new one.

If the unit is not new have you checked the status of the battery and is it a manufacturer's battery - some units are quite sensitive to that.
The problem may also be with the charger

Okay, I searched and searched until I found a solution that worked for me. I tried the USB thing, I got my phone to turn on once, but never to charge. Here's what I did:

(Do this at your own risk)
I zapped my battery with a 9v battery. One wire on each terminal and then held it to the MDA battery (positive to positive, negative to negative) for about three seconds. I did this about five times. (Don't let the wires touch while they are connected to the 9v battery.) I IMMEDIATELY plugged my phone into a wall charger, NOT my computer (The computer wouldn't charge my phone). As soon as it was connected to the wall charger, I turned it on. After starting up, the orange light came on, and it started charging. I was skeptical about this solution at first, but trying everything else I resolved to do this and then if it didn't work buy a new battery, but it worked and my MDA is charging as I'm typing. The original ideal came from a post on the xda-developers website by dew1989. I added the additional steps that got my battery charging again. I hope this helps!

Use the factory charger, i had that problem becuz i was using a razr charger, if nothing works call tmobile and tell them u r in warentee and u want to do a hanset exchange

I did the same thing, Blue Bay Electronics had a seven day warranty just long enough to fool me into giving a good report. Anyway look for a repair center and spend another 100.00. Good luck
