Hi, I would like some help reg, the T-Mobile MDA charging. I got 2 batteries, 1...


Your battery has been depleted past a chargable state.  This is a due to a bad design in the phone that doesn't monitor the battery power state well enough.  It actually allows the battery to be taken under the minimum amount needed to recharge the battery. 

You can fix this, but do so at your own risk.

You can simply purchase a new battery, that will work, just been sure not to let it deplete the battery totally anymore.

Now, on to the fix

-Take out the battery.
-Get any usb cable you can find sitting around. (any usb wire will do, an old printer cable, anything with a usb end that can plug into your computer)
-cut one end of the plug off. You need to leave the side on that connects to your computer. Cut off the side that plugs into a device (printer, camera, web cam, etc)
-Strip the rubber off the wire and expose the wires inside.
-Separate the wires from each other. You will only be using the BLACK and RED wires.
-strip the very end of the black and red wires carefully using a wire cutter exposing the metal wire inside the red and black covering.
-Plug in your home made battery charger to your computer. Careful not to touch any exposed metal, as it will give you a small shock.
****WARNING****
DO NOT UNDER ANY CIRCUMSTANCES ALLOW THE RED AND BLACK WIRE TO TOUCH EACH OTHER
****WARNING****

-now carefully hold the black wire to the negative terminal on the battery (it should be noted with a black circle with a - in the middle). Then touch the red wire to the positive terminal (it will be noted with a red circle with a + in the middle).

Hold the 2 wires there for 20 seconds. Then quickly plug the battery back into the phone, and then plug it into a regular charger. Give it little bit of time, if you've done everything correctly the charge light should come on.

I had to repeat the last step again to get the light to turn on indicating it was charging.

You must not hold the wires to the battery for too long, 20 seconds should do it. You can overload a battery with this trick and actually make it explode if you hold it there too long. You are well within the few minutes needed to detonate the battery due to overcharging by sticking very strictly to 20 seconds.

Just be careful and you'll be fine.

One you get a charge light give it a few minutes in the off position, then try powering up the device and keep it plugged in until you get 100% charge.

Good luck,

Peter

Mda not charging


Either your battery is bad or your soldered contacts on the inside to the charger port are broken.

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

I need the data on my dead MDA!!!


Try to trickle charge it by hooking it up to the USB and then to your computer. Let it charge up a bit then try powering it on or charging it the regular way to charge it even faster.

Trickle charging
Some Palm devices have the ability to "trickle charge" from a USB port on a PC or Mac. This means that it receives a very small amount of charging from the USB port, even if it is not connected to its AC charger. If your device is capable of this function, the charging time will be significantly longer for a trickle charge (depending on the power rating of the PC USB port). However, the device may not charge at all on an unpowered USB hub (or for example off off a keyboard).
