Strange Question? When my battery dies in the past I used to just plug it into my pc at my desk... DELL T5400... and charge the phone up again.
Though lately I have been using a hard-drive cable and I can't seem to recharge my phone on any pc??
Though I can pretty much download all the information from the phone??
I do have the dutty rom on.... though I don't think that would effect it?
Does any one have any ideas?
Under "Settings -> System -> Power -> Battery",
you find the option "When phone is on, do not charge the battery when connected to a PC".
Perhaps its activated?

If you have let the "battery die" over and over you could well have sent the monotoring circuitry below the charging cutoff point which is voltage dependant.
If the battery still charges from a wall outlet then this is more than likely the case as your wall charger will be rated at 1000mAh whereas the USB port is only 500 mAh max and if you have other devices plugged in at the same time it could well be a lot less and this will now no longer "start" the charging process.
If all this is the case then you have trashed the battery.
If not then charging through the wall socket could partly recover the situation, if you are lucky!
When (if) you get a new battery then keep it on constant charge (wall outlet, USB, car charger, external battery pack etc,etc) as much as possible and try to avoid a full discharge.
You guys are great
Thanks Guys that helped a lot.
I have always been scared of discharging the battery completely, Thank pa49 for confirming that.
I found the default setting for the battery was what jkolner said, Thanks bud .
I appreciate the help

My battery went flat and I can't find my mains charger, so I connected it to my laptop using the usb cable, with the intention of recharging it. But it doesn't seem to be charging and I can't turn it on at all. Is that normal? Will it only recharge from a mains charger when the battery's dead? Finally, is it safe to by any odd charger off ebay etc.?
I do not know if that is normal or not. However with regards to charging, I have used a Motorola charger with USB connection successfully in the car and from the mains.
If it is all the way dead, you have to charge with original charger. USB charge will not work. Nor will a Motorola charger work. I think that as long as the charger is 5volts, you should be okay. My Motorola charger is like 3v or something.
Thanks
I had the same problem. It does not charge in the beginning, however, if you leave it connected to USB, it will start charging in an hour or so. damn long, but it's better than nothing...
Tried to keep it connected via usb for a few hours, no luck, guess I'll just have to wait till I've bought another mains charger. There seem to be plenty of cheaper ones on ebay etc., is it safe to buy any usb charger?
This happened to me, and I nearly had a heart-attack until I came to these forums for a solution. Apparently, the phone has to be on for the charger (mains or usb) to actually charge the phone. This is because the operating system of the phone controls the charging of the phone. If the battery is completely dead, the operating system cannot control the charging, and so no matter what kind of charger you use, and no matter how long you leave it plugged in, you won't be able to charge the battery.
The only way to get it to work is to get a bit of charge into the battery directly - not through the phone. In other words, you need to jump start the battery (almost like you would jump start a car's battery). What I did was take the battery to a phone repair shop, and asked them to boost the battery using boosting equipment. Their battery testing equipment will be able to tell you when there's sufficient charge to get it going. Then turn on the phone and plug in the charger immediately once it's booted up (in other words, when the operating system can kick in and start controlling the charging process).
Hope this helps.
PS, there's a post on this forum somewhere on how to do-it-yourself, but in the long run, I found my way to be the easier way.
PPS. Once your phone is back up and running, never let the battery run down completely.
Same happens to Motorola V3.
It is ridiculous design flaw.
This is really annoying, I was hoping to sort this out with a new charger (in the post now) but looks like I'm going to have to go to a t-mobile shop. Will they definitely have something to charge the battery a bit, or should I start looking into buying something to charge the battery at home?
Yes you need the main charger.
I was using my other phones charger(motorola) with my cingular 8125 and battery is completly empty it doesn't charge it.
Didn't wait for a hour but if that works.It's good i love my wizard
motorola V3 chargers do work. used the missus' when battery ws completely dead. interestingly, doesnt work the other way around...... :?:
help with my dead battery
Bdcol
Could you direct me to that post on how to charge a dead battery - I have searched but can't find it. This is a really annoying problem - does anyone know of a commercially available battery charger which doesn't need the phone OS (the battery looks pretty standard to me).
Many thanks

Today I had pluged my usb cable in my cell and when I unplug the cable my battery was 30% charged but as soon I unplug the usb cable i got battery low warning and suddenly my cell shutdown. When I start the cell it shows -1% battery and now if I chrage the battery from charger it wont showing charging (animated charging bar) but its actualy charging it very slowly but now if I again plug usb cable and unplug it the cell again shutdown instantly.
I have tried different pcs and cable but the problem still there. Should I hard reset it? I dont install new software or change any settings durring the day.
If there isn't any important data on the phone,yes , you can try the Hard reset,but most probably the cause for not charging, is something else and not the rom (OS),so Hard reseting will not boost up the charging.If the device is not charging ,its rather more of a Hardware issue than a Software. Try to charge with a Wall charger (Mains),if it charges normally,then the fault lies in the usb cable,it might be faulty or try with other usb input port on the pc,but if it still doesn't charge with the Wall charger,than most probably the mini usb port of the phone is faulty or damaged or it might be that the battery is giving upon you.Confirm and check all these options.
I have already tried the external (home) charger and different usb cable and pc.
I cant hardreset as the battery is lower then 50% charged.
Just for your knowledge that the active sync is working fine and ithink mini usb port is not totaly dead,
And the orange light on top is keep blinking when I have plugeed usb cable.
And battery status show +21mA and +68mW only. What it should be?
BTW battery status icon bar keep animating while I have pluged usb cable. does it mean its charging.
Also let you know that this morning my battery last to below 10% charged and after that the problem starts.
And after pluging usb cable for few minutes if i do softreset then after reboot the system shows few % battery charged ( around 10%) but its drains very fast (in 2-5 minutes).

Ah !
So it has gone below the retention charge, required to start the charging circuit ,thats why its not charging.
Now either try to charge with a wall charger capable of out put of 1.0 amp or you need to 'Jump' start the battery.
i dont understand can you explain it a bit more.
This it what he's trying to say:
The battery has a well-documented bug. If you drain it below a certain amount (around 5% IIRC) then it can ONLY be charged from a wall charger, regardless what else the phone says or does. Your symptoms are weirder than usual, but not too surprising.
Replacement batteries are cheap and readily available. Start shopping for a new one while you leave the phone on the wall charger for at least 6 hours, with the phone OFF. This is a last-ditch attempt to recover your battery. If it still misbehaves after that, it's probably toast.
Thanks for explanation.
does the usb cable hack work (connect the red and black cables to battery + and -)?

YUP !
Thats what is 'Jump' start.If the battery is only below the retention charge,it can be very easily recouped by this trick.If it works fine,otherwise get a new battery,many have recovered their batteries by Jump start.

OK jump start do the trick (charged the battery) but my phone is still draining the battery very quickly (around 1% a minute) and I havent check the home charger or usb cable charging.

ok,good if it has started to charge,now don't ever let it fall below atleast 30%,how did you charged it if not through home charger or usb cable,get the battery fully cgarged with home mains charger and then check the drainage of the battery.
Secondly,either the battery cells have gone weak and not retaining the charge for long or you are using GPRS more often,coz it drains the battery quite rapidly.it all depends on your usage.
I just charged the battery from naked usb cable and it charged it but the battery drainage problem still presist and if I charge the battery from usb or charger the os dosent shows it charging. I think i should look for new battery.
Can you explain me what kind of battery should i choose for wizard as here too many local batteries are available and I dont know about correct specs for battery like mah, mwh, volt, etc and kindly also let me know I also doubt on my home charger what kind of charger should I get (mah, mwh, volt, amp)?
BTW I dont fully charge (100%) the battery yet, do i still need a one full charge and I also dont shock the battery by 1amp charger aswell.

Yes ! you must first fully charge the battery and than check the drainage.
Secondly I can't recommend any specific battery,check the specifications on the battery and verify it.
If the home charger is doubtful,you shud get an original PDA phone charger capable of 1.00 amp out put.
ok I also don't able to installnew rom on it, its giving me erorr that phone is not connected to usb cable etc.
Now the active sync is not bieng connecting too and I think now my mini usb port is faulty is it repairable?

Yes it is repairable or replaceable for that you'll have to contact the cellular company from whom you bought the phone,if its still under warranty. Otherwise get it repaired from any mobile repair shop.
ok may I know from where you belong?

Hi all,
I've noticed that when I plug my HD to a PC but with "Don't charge battery while connected" option enabled (I keep my phone connected to a cradle while at work, and I don't want to keep it charging for so long) the battery drains very quickly. It can take about 3 or 4 hours to waste a full charge.
Anyone has experienced the same?
BTW, ActiveSync is on.
Thx.

Enable the option to charge while connected, it will not damage your LI-ION battery. LI ION batteries are damaged on repeated full discharges, however this is limited by the in built circuitry to protect the battery. Also, charging through USB will be slower than using your charger as the current supplied is a lot less.
Thats right.. last night i left my Leo charging, today when i woke up i noticed that the battery level was very low so.. i unplugged it and plugged it again, noticed that the orange led wasnt lighting up, neither was the phone charging.
The phone gets very very very hot when plugged to charger or USB port on my computer and does not charge at all.
Tried it all, left it all day long with the battery out of the phone, tried charging without it in.. and nothing..it just gets very hot where the connectors (pins) make contact with the battery.
Now im trying to charge the battery on a cradle to flash it with stock rom and SPL to get it to warranty..
Any of you guys has any thoughts?
I see i posted in the wrong section.
Thank u mod
Do you always charge via usb into pc? Is your cradle plugged into the wall or pc? I don't know if you have done this, probably so, but check in windows settings->system->Power and inside the battery tab see if the "When phone is on, do not charge the battery when connected to a PC" is checked.

Yeah.. it crossed my mind to check for it, and that option is unchecked.
Though the charging "orange" led doesnt turn on even if the phone is off.
I usually charge it via usb->pc, allthough i tested with the wall charger and nothing.
I suspect it must have been a power surge that burnt in some way the PBC of the "charging module..thing"
Thanks for the suggestion
i'd check that none of the pins for the battery are in contact with each other if there is heat in that area.
Ok, I'm assuming then that the phone works, but just has low battery at the moment. If that's the case then it doesn't appear to be the battery or the leads. Any chance it's the cable? That of course assumes your using the same one with the cradle. I ask because my device didn't come with a wall charger, just a usb cable so I had to get a few extra plus a wall plug-in with a usb port.

Weird, but unfortunately it didn't. I think being in the US and getting the device from Telstra in Australia may be why I didn't. Well, if it is a hardware problem and you can't get it to charge from the device, I believe you can get a cradle that will allow you to charge the battery independant of the phone. I know it's not the best option on the planet, but it would get your battery where it needs to be to flash and confirm whether or not it's a charging issue with the battery itself.
Come to think of it, this did happen to me several weeks ago. I plugged the phone in before bed as usual and noticed the charging light didn't go on and the battery drained overnight from about 60% to 15%, which it shouldn't have done. Not in standby at least. Soft-reset the next day fixed it. It hasn't done it since. I was installing a bunch of things that evening, which may have been what did it.
I had a same problem with my hd2 and by some miracle and few days of pain
it workd again...and it workd about 5 days and same thing happend al over again...and I think I have solution!
It may be stupid but it work for me...

If you can get a voltmeter that can test low voltage and use the test leads to test the positive and the negative pins, look at the battery to figure out witch ones these are as the battery is marked positive and negative. Also make sure you have your phone plugged into the wall charger while you are conducting the testing. I am not sure what voltage reading you should get as I don't know the exact voltage it takes to charge the battery, but it should be a pretty low voltage. If you get a reading between the positive and negative you are getting voltage to the battery and your problem is either software or your battery is no longer any good. If you don't get a voltage reading then you are not getting voltage to the battery and you probably have a hardware problem somewhere in the phone.
Also is the led lighting up when you plug the phone in to charge?
Ok I just tested my battery leads with a tester. I got a constant 00.3 volts on my tester testing from positive to negative. If you are getting this reading you are getting voltage to your battery. I would take a very close look at the pins(leads) that connectar to the battery, especially if you do a battery pull as your means of reseting your HD2 instead of using the reset button. A lot of wear and tear on these pins can cause very minor bends in them that can cause all kinds of ptoblems for users. Use a magifiying glass if you have to as they could be such a small difference in the pins that you can not tell with hour naked eye.
What I am concered about though is the fact you say your led is not lighting up when you are plugged into the wall charger nd that you have tried another battery. Also just for your benifit I recomend using the wall charger to charge your phone as the computer does not charge as fast, leading me to think it does not put out the same voltage. Anyway though you can try a hard reset and see if the led comes on then. If not you most likely have a hardware issue.
Also if you can not get it to work you can always buy a external charger to charge your battery. But I also suggest you get another battery if you do this so you can always hve a charged battery to uze while the other charges.
What os? Do you have magldr installed? Flashed any roms or radios lately?

Well, it could be the battery went bad. You'd have to replace it to find out.
As a last resort, you could also buy an external charger off ebay. They are inexpensive. I have one for my backup battery.
EDIT: I just remembered the check box for "Do Not Charge My Battery" in the settings menu under Settings / System / Battery. There is a check box, but this should not affect the wall charger.
