Hi,
Can somebody tell me how to charging the battery when there is no
OS on the PPC.
I need a full battery to upgrade or flash a rom version on the PPC.
With a low battery it gives error when i want to flash a rom on the PPC.
Plz. help me.
Thnx,

Why not just connect it to the external power?
Flashing is always safest whilst connected to a power supply.

Also, you can charge battaries from USB by mini-USB cable. OS does not needed to charge.
Hi XShell,
What do you meen with charchinging with the mini USB?
I have tried with the USB cable from my MDA connected with yhe desktop
and i tried the battery charger with the adapter and the mini USB connector at the other end, and both methods doesn't works.
Normally you get a orange led when it's charging the battery but both method it's not burning.
So please tell me what you meen.
Thnx,

Here's the way to charge battery directly from charger.
This method was invented by Jasse from PDAclub.pl, BIG THANKS to him
Scheme is in the attachment. You need some charger, it must be between 3-6v. Cut off the plug, then connect red cable to minus, and black/white or other to plus. Hold the cables in that position for 2-3 minutes then try to flash. Remember: If battery will get too hot disconnect it immidietly.
YOU DOING THIS AT YOU OWN RISK
Hi J-A-J-O,
How must i hold the battery?
Should i hold it with the text up or down?
Thnx,

Here's the 3d painting Now every thing is clear.
Seems like your charge controller is dead...
And flashing ROM wouldn't help, i think.
Btw , since allways , Red = + and Black = -
Perhaps someone is reinventing the electronic way
of electrons working??? :twisted:
Cheers

Actually, I think the OS has to be present to allow charging. I noticed mine wouldn't charge until everything was fully operational when I was updating my ROM. The lack of charging capability is one reason the guides say to fully charge the magician before attempting a ROM upgrade.
Hi J-A-J-O,
I think the reply that red is plus and the black is minus is correct in the standard electricity.
I also tried to charged the bat directly with a adapter both in two ways
I meen that the plus and minus i have switched it but both way i didn't get any results.
So anyone please help me.
Thnx,

You should try to charge battarie in other Magician (from friend or others).
I also have charged in both ways, but black - minus, red - plus is 100% correct, I already change it on my pic. When I finnaly turn my magician on, the battery was charged in 90% so this method works. You can try to hold cables longer example for 5 minutes, but disconnect when battery will get warm
You still can't turn device on, you can try my method with battery cover
Hi there
Even before I bought my Treo, I knew it wouldn't charge through USB. Since I didn't want to fiddle with the power cable at the same time as I was syncing, I only connected via USB for as long as it takes to sync and then disconnected again.
But today, I forgot to disconnect for quite a while. When I noticed, I expected the battery to be down, but it was back at 100%!! I will test this a bit more, but has anybody else noticed this? Or is the battery meter confused?
Cheers

I read in another thread somewhere that the USB sync cable has a bit of trickle charge to maintain the battery level but not fully charge it. It would obviously be great if it does charge the phone, then I don't have to go out and buy a USB sync/charge cable. (Don't like lugging around the charger).

Thanks for your feedback!
My observations today are that it really is charging - slowly but surely! I might get the 650 cable mentioned in Jason's blog. Thanks for link!
Cheers

hmmm....
Well having had my Treo 750 for 2 weeks now if I have ever left it plugged in all it seems to do is suck my juice I just disconnect it after using the USB! oh Well, looks like it's cable buying time for me!

I got a combined sync & charging cable from gpsforless - works a treat
Well after reading this post i tried and test my 750v for a whole day. My observation is that yes it does charge but very slow. When i connected my Palm battery was at 82% and even after playing and hacking my palm whole day battery was still at 82%, which mean it does work.
Dear Sir,
I bought a new HTC Touch pro 2 and I need to have the right advice regarding the first time charging the battery since in the manual theu said 3 hours and one of my friends advised me to leave it on the charges for 8 hours.
my question to the experts is as follows:
1-how many hours you advice to keep the new battery on the charge?
2- For next time charging, do i need to keep it till it lights green ?
3- when I am supposed to re-charge it ( till the battery reaches 0 % or 30% )?
Please advice
Regards,

On my experience no matter if you charge it all night or charge only a few while, after 3 or 4 years you will have to replace your battery
So use it as normal in the way you want and enjoy!
Charging - need some technical help
Hello everybody,
Since the best phone ever died (or better: drown) on me (HTC Universal OFCOURSE!). I had to look for a replacement and TP2 seemed like the best of bad things. LOL!
I noticed that the wall charger had a 5V -1A(mpere) output. My (standard) car charger has a 5V - 0,5 A output. So I got the notice "your current power supply... not enough ...close some ...."
Besides the fact that e.g. tomtom uses more than the charger can give, i was wondering :
is it BAD for my battery charging at 0,5A instead of 1A ?
how much A does a laptop give when charging my TP2 trough USB port?
HAs this got sth to do with the fact that in some programs there is an option like "do not charge while connected to PC?"
I know this is more of an offtopic question, but I hope there is somebody with enough electrical knowledge to help me out!
THX!

When i plug my samsung omnia to the usb port it starts charging automaticly. This can be turned off with a third party app but it is really a pain in the butt as it makes me change the registry every time.
Anyway, i read somewhere that nowadays batteries won't get damage if you start charging them even if they aren't fully drained. Something like "baterry memory effect is a thing from the past."
Is this true?
Thanks in advance!
No, USb charging is the best way to charge your phone according to sticky over in the Nexus One forum. It emits the least ammount of energy to your phone making it less damaging to the battery. Car charging is the worst due to such a fast and high volume transfer rate.
I would agree, usb charging is much better than using the mains and heaven forbid using a car charger.
The usb does not give out the full 5v and while this may be a problem for usb cd-dvd’s or usn hard drives it is an advantage to us as this has the effect of trickle charging the battery and if done correctly this will in time condition your battery.
Many years ago I had the old SPV E100 and this came with a desktop cradle and I used to leave my cradle at work and drop my phone in to the cradle and use the activesync remote control to respond to texts or ‘play’ with my phone.
The E100 would barley last a day on a full charge and the cradle could not charge directly and you had to plug the charger into the cradle to make it charge. Then posts started appearing stating that with a single wire you could make the cradle charge from usb and I quickly made this mod to my cradle and hey presto I was charging from usb while at work.
I did not realise at the time the benefits of usb charging but I used to put my phone on the cradle in the morning, take it out during lunch, plug it back after lunch and take off when I go home and I used to do this almost every day and after six months or so I noticed that I could take my phone off the cradle at 5:00pm on Friday and it would still be running by Sunday lunchtime and all through usb charging.
I think I was lucky as the battery would only last a day and if you did the same on a modern device with a battery that lasts say three or four days it may not work out the same. I now have the TG01 and you will see by the reviews it has a very low capacity battery and using the same kind of trick it seems to be doing the same, its early days but so far so good.
What about day to day random connecting the phone to the pc via usb?
What about day to day random connecting the phone to the pc via usb for any other purposes than charging? Like activesync?
I use to connect a few times a day for periods of 4 or 5 minutes and then disconnect, and i am afraid of batterry side effects.
Should i be worried?
Hi again, officially speaking it should not make any difference but I would avoid plugging in for such short periods of time.
If you have a newer HTC device you may be lucky enough to have an option in the power settings something like ‘disable charging while plugged into pc’ if you tick this box you can plug and unplug to your hearts content but you will not charge.
If you anticipate being plugged in for quite some time then disable this option (if you have it). The only other way to avoid this is to look on Ebay and you will find usb sync/charge leads but you will find some with two usb connectors. One for data only and one for power only so you can charge without syncing or sync without charging or plug both in and sync and charge.
Fortunately for me once its plugged in it tends to stay plugged in for the rest of the day.

Thanks you so much for replying back. I don't have that option you mentioned but i downloaded a app that turns off usb charge. But thats a pain to do because it makes me mess with the registry everytime i want to turn that option off.
I would use bluetooth but i can't make my phone sync with my pc with it. I even created a thread asking for help but i got no awnser back http://forum.xda-developers.com/showthread.php?p=7257183#post7257183
I am a bit lost here. Anyways thank you for the help. At least now i know that it isn't that risky, although sometimes i need to connect my phone to the pc for text messaging or any other stuff that doesn't take more than 10 minutes.
Damn i would love to sync my phone with pc via bluetooth or wi-fi..
Noob here, not the OP, but thanks for this info. I had no idea car charging was a bad thing. Will make a habit of charging from the USB in the future.
Hi again, just read your other post and I remember when I got my Omnia I had to use bluetooth sync as it did not come with a cable.
I used this http://www.geekzone.co.nz/content.asp?contentid=3163 guide.
I know it says Windows XP but once I had my phone set and I plugged my bluetooth dongle into my work machine and set the comm port it worked and that was Windows 7 also.
On the downside syncing via usb will suck your battery pretty quickly (about the same as being on a call)
I have an iPaq 111, part of the 110 series. It's been stored in a closet for over two years. I hooked a batter charger to the battery itself (outside of the device) to charge it up enough to be able to take a charge once I put it back inside the device.
Once I did that, it powered right up, and everything worked perfectly. Then I went to unplug it, and surprise to me, it shuts off.
I've tried EVERYTHING, HP doesn't even publish there ROM. Found a setup utility to download to my PC to access my iPAQ, but it's in German, and high school was a long time ago so it's hard to understand; but what I can understand enough is that it cannot find a device. Same goes with the extension I installed through HP's website, it only finds my HP computer.
I've plugged it into my computer and the light is GREEN, suprisingly, but it does not turn on. If I plug it into the AC power adapter, it DOES turn on, stays green, and once on the homescreen, shows battery at 100% (was 23% onwards today when I was charging it). My voltage meter shows about 4 volts coming from the battery. Contacts on all ends are clean. ROM issue? Yes, I have tried soft and HARD resets.
Any help will be much appreciated. Please please please! THank you!
Battery is not fine, its dead. The proof is the fact that on AC power it turns on, but not when connected to.USB. AC power has enough amps to directly power the device, USB does not. When connected to USB power is indirectly drawn, as the phone attempts to use battery power for operation while charging it at the sametime, thus lessening the total draw. It still however needs battery to work.
Basically, the battery is dead. By a new one of eBay.
icenight, THANK YOU for the reply, it was so quick. I have figured it was the battery, BUT:
I've checked the battery with a voltmeter and it shows over 4V- using my good Fluke. Also, when it's plugged in, it progressively showed the battery charging and it's now at 100%...
Are you still thinking it could be the battery? Not enough amps from the battery? I hate to sound cheap, but it's more about the wait- I want to eBay this iPaq since I don't use it and it keeps getting in the way!
Thanks again
iPaq still not working
New battery arrived. Still does the same thing. I've read around and it could be the ROM, but it wont stay on when plugged into the PC USB port. Computer sometimes makes a noise when I plug and unplug it though. Even put a homemade "in-line" power supply to it using a 5V 1.5A adapter. This allows it to stay on when plugged into the PC usb, but there is no communication. This thing is a pile of **** I tell ya.
Any help would be so much apprecaited. Thank you so much. I can barely get past these "captcha" thingys.
Regards,
Robert
