MDA II Will Not Charge Unless Laptop Is On

Hi folks,
Love my MDA II, but I can only get it to accept a charge when my laptop is turned on. If the unit is not plugged into USB or the laptop is not on, it won't charge.
What am I doing wrong?
Finally, I have noticed the last few days that the wall AC adaptor has not been plugged in, yet the MDA has been charging through the USB when the laptop is on.
My question is what is the point of having the AC adaptor if it serves no purpose.
I rechecked and pulled the USB and plugged in AC adaptor. No charging takes place.

you are doing nothing wrong. the power thru the usb port comes only when the laptop is powered up (whether the AC power is on or not ).
In other words u can
1. charge it from your laptop's battery but the laptop has to be turned on and it does not matter if the AC power of the laptop is plugged or not
2. you can charge the XDA directly thru its own AC adapter, independent of the laptop

The AC adapter does have a use, you can either use it in conjunction with the little square dc converter that you get free in the box to charge up the xda without the cradle, so you could have the cradle at home and tyhe AC adapter at home if you wished, and if you plug the AC adapter into the cradle you can charge an aditional battery, as the additional battery can not be charge via USB, Maybe xda developers may be able to frig the cradle to charge the additional battery in the future (hint hint)

Cannot charge with car charger can any expert help please

Cannot charge xda executive with car charger ,when connected nothing happens light does not go red and also the connection icon does not show

make sure you dont have a faulty charger... dont know what you are using but i believe most people use the cigarette lighter to usb converter and then just use the usb cable... also have you tried pressing the on and off swith with the charger plugged in ?

car charger
Hi and thanks for the fast reply mate <yes it is a new charger from o2 .
No i have not tried the on off with the switch ,but would i still be able to charge when i am using tomtom

Whell....I use the cigarette lighter to usb adapter and usb cable ...at times i have had to quik press the on/off swith and at times plug and unplug the cable to get it to charge ....I used this as a "jump start" method only and no problems after that with using it whillst on charge (even with tomtom)..... other than that you may have a faulty charger or fag lighter to usb adapter (I never seen what a o2 one looks like).

Is the charger one especially for the exec?
I found normal usb chargers for phones like V3 or a GPS charger cant supply enough current to charge an exec.

hi, yeah i have had this problem, and so have a few of my clients, seems that not enough juice flows through the non branded versions, unlike from o2's or Brodits cables

I found that a regular USB cable into a Cigarette Lighter -> USB Socket didn't work until I joined pin 4 to pin 5 on the USB B Mini plug. All of the adapters I had that worked, but only powered (no data, i.e. Brodit and mains adapter) seemed to have pin 4 joined to pin 5 (pin 4 isn't normally connected at all). Once I did that mod it worked fine.
Cheers,
Steve.

Orange shops carry a charger intended for HTC manufactured devices (i.e. the SPV C500/M500 range) which works fine. Only £9.99.

Wizard Car Charger

So I visited my local Walmart and discovered a car charger, designed for Blackberry 6200 through 7500 and Motorola RAZR series phones.
The connector is the same, mini USB B.
$25,000 Question: Can I use this to charge my TMO MDA? Same connection, just worried the voltage or wiring might not be the same.

The AC chargers that came with my Razr and MDA are the same voltage-wise (5V) but not the same Amps.
MDA is 5V 1A, Razr is 5V 0.5A, they are not the same
However, it shouldn't damage the battery, just charge slower.
Just so you know, USB ports output 5V at 0.5A as well.
Edit: Sorry, I realize I completely changed my post, but didn't want incorrect info out there.

Thanks...I figured that, but was just making sure.
I got it in case of emergency...I almost always charge via USB; just leave it plugged in all day.
But you never know.....
Thanks!

Don't expect it to charge if you battery is below 30-20% charge. I'm not sure why this is an issue but it has bitten me in the rear once already.
Does anybody know why it's a problem for "less-than-1amp" chargers to charge back from the low threshold?

boxwave.com sells a 1 amp car charger. It has a USB port, so you just use it with any cable that normally plugs into a USB port. Since my Globalsat GBH-820 BT adapter came with a cable with large USB at one end, and _two_ mini USB at the other end, I can charge the GBH-820 and my 8125 at the same time.

That's not true,... if you use the VersaCharger like I do. This is where I learned of the "charging only" cable that Boxwave sells (how conveinent) and then they sell a Sync/charger for USB only. I have a Boxwave VersaCharger that I can't use without buying their "cable" to make it charge the 8125. I found this out because I have a Belkin retractable sync/charge cable that doesn't work with the VersaCharger as I had hoped. The cable that you have may work with 1amp charger but it probably won't work with theVersaCharger.
What is the output on the "min-usb" connector end of the cable? This sounds like the cable that I need for the 2 devices that I use.
...I wonder if they are putting some electronics in the cable connector...?

I bought the bundle that had a car charger (I have the regular; not the high output; not the Versa) and two mini-Sync (retractable) cables. I got caught by the fact that one of them is "charging only" when I was trying to use the "charging only" cable between my laptop and my TI-84plus calculator. I switched to the mini-USB cable that came with my calculator, and it worked fine, as did my phone with AS. That's when I looked closer at the two mini-sync cables and noticed that one was for "charging only". So, that mini-sync cable (the charging only) stays in the car, and works fine for charging my phone or my GBH-820. The really odd thing is that the "charging only" cable looks "thicker" than the one that works for syncing. Maybe lower gauge wire to help the higher current flow easier.
I have also used my other USB-miniUSB cables with my car adapter. E.g. the cable that came with the phone, the cable that came with my TI-84plus calculator.
My Bluetake headphones came with their own USB cable that has, for lack of any better term, an ultraminiUSB (or some kind of proprietary connector, cause it's not marked with a USB symbol like the other cables) plug at the end. I just plug the regular USB end of that cable into the car charger, and it charges the Bluetake's just fine.

Excellent car charger for Wizard
I have purchased and used the "Ecovell 4x USB" adapter on both a Wizard and a Universal. It provides a 2 Amp output which is equivalent to the AC adapter and works with any mini-USB cable. It will charge a Universal from absolutely dead which I have not been able to do with any other adapter. Here is the link to the item on Yes Depot:

I've ordered from them and the service was OK. I haven't seen the item available anywhere else.

Silly Charging Question

So this may be a silly question, but I've just received the T-Mobile MDA (HTC Wizard) second-hand and without a charger.
The Mini USB port on the bottom allows ActiveSync and charging from my notebook's USB port, but when I try to charge using an AC-to-USB adapter it doesn't work... I've tried two different Motorola phone chargers and a generic one that came with my Jawbone that has a USB female connector on the adapter and you supply your own USB cable. I've used the same cable I was using when attaching to the PC, but no luck.
Interestingly enough, I did get it to charge with the same USB cable once at an airport by plugging it into the Southwest Airlines chairs with the USB power plugs...
So does anyone know? Does this phone require a special sort of charger?

you need a charger that is rated 1.0Amps.
usb is normally 500mAmps, not enough to charge your phone.

HD2's data cable.. is it micro USB?

I can't seem to find a usb to "whatever it is" wire selling..
is it a standard micro USB port?

yes... u r rite... itz a MICRO USB...

But it can't supply power to a USB device, so it can't be used like a PC USB port. It's only good for recharging and syncing.

so if i want to buy an additional wire, i look for a USB to MICRO USB wire right? no need to buy from HTC right?
cause i saw one usb that is smaller but it doesn't fit.. is there a MINI USB port too?
am confused

Erm yes it can,

Actually better take the device with you. Sellers here told me there is like 7 different very similar connectors. However this one should be the standard micro USB, which is supposed to be universal charger/sync cable in the future (at least in EU).
And yes, of course, there is mini USB. And there even are more versions of mini USB, for example HTC used their own.

You had better use HTC cables. HD2 is microusb, but not all microusb cables are good for HD2. Like iPhone, it takes a large charging current, and many no brand cables cannot do it. I've got a third party cable that syncs only, but if charged from the PC, the HD2 will say that the charging current is too small. Battery actually drops when I connect HD2 to PC using this cable (because my options set it that backlight is always on when HD2 is connected). Other combinations are OK:
original cable + AC plug: charging OK
original cable + PC: charging OK
third party cable + AC plug: charging OK
third party cable + PC: "insufficient charging current"

Be careful with cables- you'd be better to buy the genuine HTC version.
Many USB/MicroUSB cables are for charging only, and don't have the data pins connected. Thats OK if you just want to charge it while you are away from your main PC or power supply.
You can also buy a miniUSB/MicroUSB adapter for charging using and older miniSUB charger, but again these don't have the data pins connected.

I bought a number of 3rd party USB to microUSB cables a month ago for sync and charging (office, PC, bedside charging), so far so good... no issues (maybe I'm lucky). The OmniaII uses the same connector, so I'm using the HTC car charger to charge both.

I bought Nokia's cable (for E71,N97,etc.) and it work just fine with charging from laptop. much cheaper than HTC in here.

if you are going for the cheapo option...

i got a couple from ebay - arrived the next day. - charge/sync fine.

charger from iPhone
The iPhone charger coud be used for charging HD2. Just plug the microUSB cord instead of iPhones and ... voila. The same outputs

N86-8megapixel cable doesnt work..
So I managed to leave my HTC cable at work (2 days after getting the Telstra HD2 in OZ) and now I am on 4-5 days leave from work and really want to tinker with my phone. I think I may end up having to go back to work to collect the HTC cable - as below... challenge to get non-HTC cable to work.
I found that my wife's N86-8megapixel nokia has a similar micro-usb cable.
When connected to the PC the phone starts charging and the PC does the "doo-doop" sound a "appears" to connect to the phone, but active sync cannot detect the phone \ sync.
I see others have had success with nokia cables - I am wondering if there is something wierd going on.
