Does anyone know if the Wizard is capable of charging its battery in a completely powered down state?
The battery on my Wizard (G4 Qtek 9100) was low today, but I just ignored it, the battery ended up running down completely to the point that the phone powered off, and would not turn back on when I tried to repower it. I connected the charger and left it sit for about half an hour, the charging light did not light, but I left it to charge. After the half hour I figured it should have gained enough charge to power on, so I tried and no luck. Luckily I have a charged spare battery, so I left the dead battery in the phone and wedged thin wires in between the dead battery contacts, and the phone's spring loaded contacts. I connected the + of the dead battery to the + of the spare, and the - of the dead to the - of the spare. Now both batteries are connected to the phone in parallel. This allowed me to power the phone up and boot it all the way up, where the charging indicator LED lit. I disconnected the spare battery, so that the dead battery can charge on its own. Sofar it looks like it is taking the charge.
I'm wondering if some of the people that have "bricked" phones might have run into the same problem that I have. If you have a "bricked" phone, try using another battery that you know has a charge.
go in registry with totalcommander or something similar to this key:
HKLM\Drivers\BuiltIn\usbfndrv
and change : EnableUsbCharging to '1'
press reset after u done this.
i had this several times with death battery and wouldnt charge on usb on the
computer but it did with the original charger.
Thanks, i'll give that a try. Just curious, do you know anything about how that works? I'm wondering how a registry key can controll a piece of hardware that has been completely powered down, and that windows mobile hasn't yet booted on.
Hello,
I've a Wizard that is approximately 20 months old. Yesterday, before I went to bed, I set the alarm clock on the Wizard, put it next to bed and went to sleep.
This morning upon waking up I tried to switch on the Wizard but it couldn't. Firstly, I thought the battery was discharged, so I tried charging through USB on my computer -- it wouldn't charge or start. Then, I tried charging on the default charger -- again nothing.
I tried removing battery and soft reset - nothing. It's really weird, yesterday I left it working, no-one has touched it and today it's totally non-responsive.
Any ideas what might be wrong/how can I bring it back to life? Would a hard-reset help?
Regards,
1. how much charge was in the battery last night?
2. is your battery 20 months old also?
3. do you have a spare battery to try?
4. do you have many applications, music etc. on the device?

Unfortunately I can't remember, however I have an alarm which sounds periodically when the battery is below 20%, so I'm guessing I had at least 20 percent. Could be wrong, of course, but most likely above 20%.
2. is your battery 20 months old also?

Yes, this is the original battery. Aprx. 20 months old.
3. do you have a spare battery to try?

I don't have that. I guess I could go to mobile phone service shack and check there. Do you think it's the battery?
4. do you have many applications, music etc. on the device?

The Wizard came with a 64MB card I think. I had around 10MB free space. 3-4 applications, 2-3 mp3s. Nothing unusual.
Same thing (sort of) happened to mine after about 187 months. I was using mine and it hung up. I hit the reset button and that was the end of that. Even when plugged in it does nothing. Tried a hard reset... nothing. Soft reset.... nothing. Dead. Zip. Nadda.
Good news? Replaced it with a Kaiser!

Mine died too when i was flashing...
Leave the phone in the original charger for a while and see if it picks up...sometimes it comes back to life by doing that...
If that doesnt work, try a new battery, you might be lucky...
A somewhat strange development occurred today:
Today (3 days after it stopping working) I randomly tried to switch the Wizard on and it indeed switched on. It showed that it had 0% battery. It didn't even show 0%, basically the battery charge graph was empty - no number, no fill, nothing.
While it was on charge the charge light was on (while it was 'broken' the charge light was off when I tried to charge). So I left it to charge and when I checked back in 15 minutes it was back to being 'dead'. Can't be started, no charge light, nada.
I don't really know what's going on, however I'm highly suspicious of the battery. Currently, I'm periodically trying to switch it on again so I can backup my data.
Any ideas what might be wrong with it, do you think it's the battery or is it more serious?

The battery won't charge if it gets to low.
There is a thread about using a 9V battery to get the battery up to a level so it will charge. I don't have the link for it, try searching for it or maybe someone else will reply.
You might have a bad battery. I bought a new battery because I didn't think I was getting the life that I should. I tried using the old battery about a month after when I had to run out and my main was low. About 15 minuets later my phone started shutting of and rebooting. That was the end of that battery.
Yep, it's possible. If the battery is to empty, you can't charge the phone. It is stupid but it's just like that. You also can't power on the phone without a battery with the charger connected.
Yesterday I received my wizard and I had to revive my battery too because it was completely empty. I used a self made 5V power supply and after 2 minutes charging I placed the battery in the wizard and was able to charge and boot with the charger connected.
Here's the 9v battery trick, connect the + from the 9v battery to the + of the phones battery and the - to the -, hold there for only 10 seconds then remove the connection for 10 seconds and then repeat the process about 8 to 10 times and then put the battery back in the phone and connect it to the wall charger to fully charge.
Thanks for the advice. I'm going to do the jump-start thing.
However, I've hard time determining which is the - and which is the + pin layout on the battery, since the label is not correctly applied.
As far as I can see the - is the one at the far right, however I'm not sure which is the + pin.
Can someone help me with this, please?

When you take out the battery and put it back in that direction ,turn and face up the connector side fasing you,the first connector from the rightside of the battery is the ' + ' and the last is ' - ' towards the leftside.Be careful while connecting and try not to touch other connectors. Don't keep the connections longer then 10 seconds interval.
good luck
Xeno1,
My MDA battery also died and went below re-chargeable state. Your trick to use 9volt battery to jump-start it worked just fine for me. I connnected for about 20 seconds (2x times) and plugged it back into phone and connected USB cable to it and my nice yellow charging light came back on. After about 30 mins, I could use the phone.
THANKS FOR THE GREAT TIP!!!
easier fix, take a standard usb cable. rip off the smaller end with a wire cutter, expose the red and black wire. take out your battery, than connect the negative(black) wire to the negative end of the battery, than the red wire to the positive end of the battery, leave it in there for exactly 3-5 minutes for jump start. after that turn your wizard on, and quickly shove it inside a new usb cable. or the wall charger.
note:
if not done correctly, you may damage your wizard or the battery. if theres a power overload or your power goes out. your wizard will burn out!
feedback is greatly appreciated.
p.s after that my battery seem to be weak, charge barely holds for 12 hours. after 12-14 hours it will die out. so i suggest buying a new battery after couple of days.
Thanks guys! Vario died yesterday and wouldn't turn on or charge.
Tried the 9v battery recommended here and it worked! I was a little unsure which end was - and which was + but using the advise above, got it right. Wasn't too worried as found and ordered a replacement from ebay this morning for £7.
The first connector on the right hand side, nearest the end of the battery is the + the one more towards the middle and further away from its corresponding end is -, or at least, thats what worked for me.
Thanks again!
Experiencing the same issues after I set aside my Mini S as it was experiencing problems with regards to its screen alignment. Wasn't able to charge it during that time I kept in the drawer unused - due to frustration as I can't use it anymore. After downloading a guide to disassmble it so I could remedy the problem I found out that it won't power up anymore even with a new battery.
Well, haven't tried the jumpstart thing and the original battery was disposed of already to try the jumpstart idea. Could it be the internal battery is causing the problems? I opened my unit up and tested the internal battery for power and it registers a measly .2V left. Will use the 9V thing to power it up (as been doing that before on watch batteries that are hard to find replacements) before I do it on the main battery. Here's hoping it works as the Mini S has been quite useful for me until now.
UPDATE: I charged the internal battery and it now reads 1+ V and the external battery at 3+ V. No luck yet though as the unit still won't show any life. Any suggestions?
Vivanov, I know it's been a few years now, but did you end up fixing your problem? If so, how?
GOt a couple of years old P3450 which has been all but faultless. Plenty of charge, was reading an e-book, checked some email and such, put to sleep and left for an hour or so. Picked it back up to carry on the e-book and the "smart mobility" boot screen flashed up for about 2 seconds and went blank.
Odd - pressed the power button and the boot screen flashed up, and died again. Plugged into the wall-USB cable which can be a little iffy - no status light, but continues. Remove battery, doesn't feel especially warm, reseat the battery and try again - same response.
Now when not connected to the wall it won't even shoe the boot screen (even if PC-USB cable attached).
Tried pushing the reset button, but no change. Don't really want to try a hard reset unless I really have to as it took hours to set up the menus and such. Not gotten wet or been dropped...
Charging circuit? A fuse somewhere? Battery was (is?) holding a respectable charge (lasts me a 3 / 4 days if I keep the BT and Wifi turned off).
Hoping my favourite gadget isn't dead
Left the battery out for an hour, plugged back in - same result. Left it overnight and it now boots up just fine - but won't charge (tried wall charger and USB).
The USB/power socket on the bottom does look a little crusty and I've tried wiggling gently with the cable(s) but the USB cable at least has been faultless.
Will try taking a can of air to it at work today but still worried it might somehow be related to the charging circuit.
Is it possible to get a charging dock with a slot for a spare battery - so I can charge that way?
Yesterday, before going to sleep I checked my mail and layed my phone next to me. This morning I grab my phone but it doesn't respond. I just charged it for an hour but still no response... Any suggestions
Remove & install battery, then boot up again?
I allready did that twice without result but after reading your reply I tried again. Now I replaced the SIM and SD card too and now it's working again! Thanks.
Don't want to bring you down but It sort of happened the same for me, I went to sleep with 85% batt, plugged the charger went to bet, next moring tried to tur on, nothing, charger was still on, tried pulling te batt out, turn on no luck. Still haven't been able to figure it out but I know my streak won't charge the battery so I'm charging the batt outside the streak ordered a second batt so no way to test cable/battery ATM, so far can't say if it's the battery but it don't look like the battery is the problem. forgot to mention, a couple of times I saw the empty battery icon, so i used a BB Bold battery to jump start the phone (just making sure the streak was ok heh), only thing I can think off is that there was a power surge of some sort and took the charging IC with it. The cable works fine for sync and x-fer files but charging is a NO go. it goes as far as telling where the power source is coming (USB/AC) but thats about it. no charge.
so before reaching my conclution i say make sure the metal contacts are touching the battery, make sure the battery has charge if you are an avid electronics guy I say check voltage on the battery and see how is that doing. I've read a lot lately to see what can be my problem and there is one tiny hope that the battery might have triggered it's security gimmick and it won't take charge the "smart" way and that is why I have to use a Li-ION "desk" charger. But I don't know that much of batteries.
I hope it guides you towards what might be happening. Not a solution but you're not alone.
***UPDATE
LOL, I realized you fixed the problem. nice one!
when you have a lot of applications running which consume a lot of battery you will notice the streak is going to tell you the charger is invalid. infact there is more powerdrainage then charging capacity. this shouldnt happen with the dell adapter which delivers 1 ampere at 5v instead of the pc which gives 500mA.
if this happens to you one time that the device wont turn on or do anything anymore unplug it from AC and detach the usb cable . then attach the usb cable to the pc and stick the other side in the device and wait for it to show desktop, should be no longer then 30 secs for it to show. (you need the dell sync software and drivers being installed)
Dell Streak 7 won't power on or off
Had my 7 for a few days now, the screen was intermittently not responding so I checked out a few forums - decided to calibrate the screen - so powered it off and then powered it back on holding the power button and the + and - volume simultaneously. Now it won't power back on properly - I just the the soft buttons lighting up. It also won't power off. I have plugged into the ac power charger and the power light does not go on at all (orange or green). It had pretty much a full battery when all this happend about 10 minutes ago.
Fixed it - buy pressing the hard reset button adjacent to the SD card slot. Now working well.
Have a TMOUS purchased in May. Latest stock rom/radio. When the battery is super low it goes through the process of shutting down - but when I plug it into the charger the phone will boot instead of staying shut down and charge. Will attempt to boot then go into Sense then shut down again and do the same process all over again. The only way to stop it is to quickly power down and it will stay down and charge. In any of the situations the phone appears to be charging.
Is this a problem with the ROM/Hardware or is something going on with the battery? Have an 8GB SD card with Android (no boot loader) and thats pretty much it.
Any advice would be appreciated.
I doubt that your battery is gone bad, but there are chances, try to condition your battery
Its just a little strange that the when the supposedly dead phone is plugged into a charger it boots up without pressing the power button. Don't think thats normal. Also when plugged into a charger when the battery is "dead" or near dead it should boot up and charge. This one doesn't - it boots - shows an LED charge light and then powers down and reboots. For some reason the battery with such a low charge can't power the phone and charge at the same time.
Will attempt to do a hard reset - maybe HD2 Tweak or something else did something to the registry and try it again. Since its under warranty will request another battery and take it from there. Don't think anything is wrong with the phone's hardware because it functions flawlessly.

If the battery drains and shuts off because it's out of juice, it WILL turn back on as soon as you plug it in, but it shouldn't keep rebooting after that...
Also if it's just shutting down on you in Android without warning when it's low, you need to condition your battery in Android so that it has the correct batterystats info.
No something is wrong. Ran it out of juice in WM this afternoon. Got the error message let it go. Went down and shut off. Plugged it into a car charger USB/cig adapter. Powered up go to tmobile screen/radio code then animation - rebooted did the same thing without touching it a few times then shut off - light led for charging did not appear.
Pulled battery - when charger disconnected - plugged charger - red light no reboot. Tried it again - same results with a hitch - it froze when it was charging - accessed internet explorer then it did a hard freeze - had to press reset button.
Don't know whats going on at this point - it shouldn't have done the freeze. So I'm going to experiement - pull the SD card (has Android on it) and try it again without the card. Try another card, try another charger and see - if I get the same results its either the phone or battery. When I have a charge greater than 5% there are never any problems. Only when battery level 0-1%.

Your battery pins aren't bent are they? (The little guys on the phone side that smash down when you insert the battery)
No, they are fine. I did call T-Mobile this afternoon and spoke to a level 2 tech - they think the battery is bad. Under warranty and have to call HTC tomorrow morning.
The phone does charge and does get to 100%. Drain in Windows seems fine and uniform but it does drop quickly once I get to about 20%.
Because of the reboot issue I think one of the cells is bad. Doesn't seem to want to trickle charge when the battery is that low. Tries to reboot - but can't get enough juice to sustain itself. Should just bypass through the battery as its charging. Either its the battery or somehow the charging circuitry is bad - who knows - with a new battery if it still does it then is the phone's hardware.
Will stop using Android for a while until this gets worked out - although I prefer the browser over WM 6.5.

Def sounds like a battery issue then, if the pins aren't bent because that is the biggest symptom of bent pins.
