I did something stupid, now my Treo won't charge - Palm Treo 750

Well I did something really stupid - was hard-wiring a car charger and plugged it in backwards - now my Treo 750 won't charge through the regular power charger port.. it WILL, however, still charge via a USB cable connected to my PC.. so JUST the power port charging seems to be fried.
Any tricks to getting this working again other than replacing the mainboard in the treo?

Are you sure you fried the charger port? I'm not sure but does the treo use a different charger port when on usb or on the regular charger port.
Did you check that no fuse was blown on the car charger? did you try it with the original charger ( it use only the charger port) and tried an other car charger?

chances are that you've blown a fuse is all... now the question is... do you have a multimeter handy?

Yes, i've tried multiple chargers.. the problem is definitely inside the phone.. i opened it up and am handy with a multimeter, the problem is the components are SO small in there it'd be hard to replace anything..

Unable to Charge HTC TOUCH PRO Via a usb/car charger

Hello,
I have a VODAFONE BRANDED, HTC TOUCH PRO phone and it has started playing up suddenly.
It would charge when connected to a pc, car charger using a usb cable or using any mini usb charger. all of a sudden it has stopped charging with any other charger except its own htc wall plug charger.
I have tried a hard reset and still no joy.
the charge via usb is unchecked and it charges when connected to a PC.
However it doesnt charge with the following methods which used to work earlier
1. Motorola charger - mini usb
2. Using a usb cable and a wall output with usb
3. car charger with a usb output.
I have a htc audio out connecter. when i connect the connector, and then charge via usb it works in the car and from the wall.
is it something to do with the pins on the cables and on the device??
I used to get a menu asking the sort of connection that i needed (activesysnc, data etc) when connecting to the car charger earlier, it does not come anymore.
Its frustrating cos i travel a lot and find chrarging with usb cables the most convenint in the car, office or else where.
Could it be damaged pins on the device??
Any ideas/suggestions will be highly appreciated.
Many thanks

Its prolly pins because the mini USB is not a perfect fit for the HTC audio jack. I would use your HTC adaptor and run the USB through that.
Something might be blocking a less than 1000mah income charge..
On low battery (as in dead-battery) you definately need a wall-plug charger. Under normal conditions the USB car charger or laptop would be fine.
Since you hinted the use of the audio jack I most likely is a bad connection on the USB pins. Did you take a look at them using a magnifying glass?

Ur problem solved? I am facing kind of similar problem... Now my Touch HD can only charge using USB cable through computer.. it will not charge using any other external AC adapter.. very strange huh?
100 % fix
I managed to solder the black negative wire to the usb housing of a male usb mini and now it charges without any problem. The housing is used as a substitute for pin 5 that is negative because it has a metal shield as standard.
to make it easier for some noobs, just get a usb female to a usb mini cable and cut it off and solder the negtive black wire to the shield cable around all the wires. AS standard all usb cable have this shield metal that conects to the usb housing.
This is a FIX if you have managed to break the pin5 when inserting the stylus in the usb rather than the RESET button.
I had a weird charging issue with my AT&T Fuze as well...
The phone would charge fine (wall or PC USB) until I got some kind of notification on the phone (missed call, e-mail, etc). Then it would stop charging. Often when it was on the charger and on, the battery would run down until the phone shut off. Then it would start charging again. I would put my phone on the charger at night (and on) only to come down in the morning to find my phone turned off and charging because the battery had run down!
Shortly after this started happening I also started to get "storage memory low" messages. Coincidentally, since I freed up a bit of the storage memory (cleared IE and Opera history) I have not had the charging problem...
mini-usb problems with charging
This is the 2nd Fuze that has problems with the mini-usb connection and charging.
Slight forward pressure is needed to get a good connection. This happens with two different cables, two different car chargers, and three different HTC usb adapter dongles.
My phone is usually plugged into my computer or my car charger, unless I'm carrying it. I keep the screen lit when on external power as I use it extensively as a PDA. It's real obvious when I lose the power connection, as the screen blanks shortly thereafter.
Do i need to send my fuze back? since I havent read a solution. I dont think its software but i turned on charging through usb and now its the only way to charge. No chargers work? Grrrr. Batterys and chargers are good. This happened to my last fuze.
not to be a prick or anytihng, but have you checked the battery settings, there is a checkbox so it doesnt charge when plugged in - i've knocked this on a few times myself
the OP already noted that that option was not checked. Please read a little before that.
My car charger sometimes need me to move the wires around abit before it starts charging. It seems to be more like a pin issue.
Mini USB Charging Problems
I had the same problem.
I just solve it by using other mini usb cable.
Now it charges.
HTC Touch Pro Charging via USB Problem Solved
I can't believe it was that easy! You are correct; There is a check-box that will disable charging via USB if the unit is powered on. "Systems/Battery" I have been putting up with this for months, but never took the time to try and solve it. Sheesh!

Can charger be used with other phones?

My charger that came with the SGS4G is not an official Samsung one. This is because I bought my phone used and it came with a 3rd party charger.
The charger is just a one-piece charger. I cannot remove the cable. It says:
AC Charger
Model: Micro USB
INPUT: AC 90V-240V
OUTPUT: DC 4V-8V
Can I use this charger with other phones that charge over MicroUSB? Do I need to make sure the other phone can handle 4V-8V?
Also I intend to buy another charger as backup, but I have this adapter which I plug in my USB cable into and then it goes to the power outlet. When I used this, my phone acted very erratic, swipes would not register correctly, phone became unstable, etc. Any reason for why this would happen?
It's sounds like your generic USB charger, and should charge anything that would charge if you were to plug it into a computer's usb port. I have a belkin usb plug, except it has a usb port on it instead of a cable, and it charges everything, even PS3 controllers lol.
Who makes this charger? If it's a super cheapo, the power may be dirty and may cause your phone to act funny.

It is some cheap USB to AC charger I got from Dealextreme. Never had a problem with my old Huawei U8100 or DSLite.

Yes and yes to the first two questions but it normally isn't a problem depending on what is charging.
To the third, I had that same problem with my ZuneHD and a generic manufacturer's cable and I still don't know why.
Sent from my SGH-T959V using XDA App
The major issue is "are the data lines shorted together?". If they are not, your phone (and other devices that use USB for power) will see it as a simple USB port and limit draw to what a PC USB port can supply (not much).
There are also some ways (particular resistors used across... pins 1 and 3?) to indicate how high the charger can go.
Most of the USB car chargers (at least the ones with USB ports) do NOT do this, so they take forever to charge a phone.
Easiest way to tell: with the charger charging, go into device settings. If it says "Charging(AC)" you're good; "Charging(USB)" not so good.

[TUT]Fast Charging via USB port MOD

Anyone wanting to know how to fast charge using the usb port on your pc/laptop?
This usually takes ages compared to charging via mains lead, the hack itself is quite simple and involves modifying the usb cable
my results are as follows (these can vary depending on what you are using your phone for, what background apps running, etc.
charging with mains lead :
4.2v
998mah
mains ac
charging with STANDARD usb lead:
422mah
3.999v
standard usb
and finally the MODIFIED usb lead hack:
4.161v
782mah
usb hack
as you can see it is a 53% increase in charging compared to standard usb charging mah, and slightly under mains ac charging mah,
as my phone is always plugged in at my work pc or home pc or laptop or whatever this works out good
TUT:
use at your own risk this is for information purposes only and I hold no responsibility to any damage that may arise
using a micro usb cable (charging cable for htc phones)
cut it using a pliers half way through the cable
using pliers again cut away the thick black wiring, the red and black small wiring, and white and green wiring
from the usb port end to the microusb connect the black and red cables together so they join
from the microusb end short out the white and green cables together
from the usb port end leave the white and green cables, do not touch these
use insulation tape/solder to clean it up and then your cable is ready
I will make a mod for car chargers also soon
see attached image showing which wires to cut and which to join up and which to leave alone, if this helped you in anyway (it should help you ) then please hit the thanks button
this mod will trick your pc/laptop/htc into thinking that it is not a pc usb cable and will allow higher currents and voltage to your phone
you can check this with current widget from market place
once this mod is done, you cannot use the same cable again for pc/usb tethering or usb disk drive, only cable can be used for charging
Care to explain how you did it? I got a spare Micro USB cable willing to try and make a tutorial with pictures.
So you forgot to put the directions for the mod...
Sent from my Sensation 4g using XDA App
directions are up with a picture
Seems awesome, but I'd be way too scared to try that on my own. >.<
First of all im not against this mod. Just want to share my experience just this morning.
I charge my phone via the stock usb cable to my pc and leave until morning approx 7hrs. What happen now my phone Menu button become unresponsive tried different method, shake google for answer , but nothing work. Worst come to worse i may return the phone to HTC for repair. So for anyone want to try this be careful, this could be a problem with HTC as it could result more problem.
HTH
Sounds dangerous and a bit risky. Why not just use a USB y cable and a micro USB adapter?
http://item.mobileweb.ebay.com.au/viewitem?itemId=370586078337
Its not dangerous nor risky in my opinion...
I am using this trick since I owned HTC TYTN2 and I`m using it now.
Hmmm...
I always thought the different voltages came from the charging adaptor..
The phone adaptors have normal charging voltages so thats why charge normal speed... however PCs have lesser voltage due to USB ports. I think the PC voltage varies on the device that's plugged in.
Thus, we can use the same cable for charging with an adaptor and also for data transfer and the phone knows what its plugged into.
Pardon me if i'm wrong... could be a misconception i had
Why go to that bother when you can just plug in the adaptor!

It's got nothing to do with the voltages, they are the same. The phone senses that the data wires are not connected together (open) and presumes that it is plugged into a pc / laptop usb port. Because of this the phone then restricts the current it draws from it's source so that it doesn't cause damage to the pc / laptop usb power supply.
Inside the phone charger the data connections will be shorted out so the phone knows it's the charger and can draw full current.
There is a chance that it could damage the pc / laptop if the usb port supply is not rated high enough
Just to update the thread, I've been using this for the last year and a half on all the HTC's I own and no issue at all,
I can connect my phone to my laptop if i dont have access to mains
I can use the cable in the car to a usb charger (which charge slow for some reason)
there are many reasons i.e. in work where I can only use a usb port and no extra plugs for a/c, it means I don't have to carry a plug around with me just a usb cable,
A good post, the issues around drawing to much power could effect older laptops
If I understand correctlly USB3 has the ability to supply more power than USB 2
Anyone any idea if this would reduce charge times without the mod?
battery will die soon enough...
you should place a 220 Ohm resistor between the data lines (green and white) if you do that, you will be able to use the where it was intended for, data
with the 200~220 Ohm resistor the phone recognizes the connection as AC-charger. i dit this with a DealExtreme carcharger
source: http://www.ifixit.com/Guide/Upgradi...-current-to-HTC-Hero-and-other-devices/5172/1
If you can get to the ID-pin of the USB-connector (pin4) and connect the following resistors to GND, you get interesting USB modes
Dock-mode = 44-49 kOhms
Car-dock = 5-16 kOhms
source: http://forum.xda-developers.com/showthread.php?t=1185431
I've done this, and soldered all the cables in the right positions, now I'm testing the charge times between this and a normal usb cable on my HTC G1.
First thing I noticed was that my phone says charging via AC, instead of usb.
Will edit this with the results.
Edit : Been a while, forgot about this, so I forget the exact numbers, but my phone charged around 1 and half hours faster with this mod, and yes, it was on USB 3.0 so its quite good.
Worthless to try if you don't have USB 3.0.
Sent from my GT-I9100 using xda premium
Does this mod increase charge with main AC lead that output 2A e.g. Ipad charger head???
usb3 provides up to 900ma
so usb3 should work without any problems
this is usb specification
http://www.usr.com/education/peripherals0.asp
by default usb2 provides 500ma unless it is asked for more by the device, this is where the mod of the cable comes into play, it provides up to 1000ma with this mod

I have an Notebook with USB3.0 and also Power-USB. (Power usb only works with a dockingstation).
The charging is also bad. Takes about ~4 hours from 2% - 100%.
I thought about power reducement by phone, when dataconnection is available. Now I know it for sure :-/

Charging broke, DIY charger broke, possible tablet issue?

Hi,
My TF101 won't charge anymore. The original charger stopped working a while back, which is when I first switched to a 12v 1.5a charger with USB tip from Radioshack. ---Insert long story about using the charger last night to charge a drill battery and possibly shorting some wires in bad ways---. I just bought a brand new adapter from Radioshack. Plugged in my tablet, the battery charging icon pops up for a second then goes away and there are no other signs of charging. Same thing happens when I plug it into one of my computer's 12v rails (similar to this). I think it might be trickle charging, but I haven't yet left it alone for more than an hour or so. Same thing happened when I plugged it into a 19v laptop adapter (swapped out the barrel tip with my USB tip). The USB tip is a single unchanged variable in all of these tests, but when I was at Radioshack I quickly tested the new adapter with a new tip, and it did not work, so I don't think the USB tip is the problem, but maybe. A multimeter shows correct voltage from both adapters and computer. I can't seem to get any reading from the female USB tip plug, but I also don't know where the put the meter leads, when I put them both inside the plug I got some sparks so I stopped.
Could there be something wrong with the tablet itself?
Thanks,
Marc
Edit: Or how can I test the 30-pin connector that goes into the tablet with a multimeter?

A510 won't charge

Since last night my a510 won't charge at all. There was a thunderstorm and a power cut and the charger was connected to the socket (a multi socket with several other items including a phone charger) but not to the tablet. When I plug it in now there's no indication that it is charging and the battery keeps going down. I tried with the phone charger also and a USB cable on the PC. While I know at best this would charge the tablet in 24 hours or so there was again not sign of charging at all.
Is it still most likely to be the Acer charger that's at fault or is there something else I could try?

12V, 1.5 Ampere, I believe just about any electronics outlet should have something in stock. Original would be better, true. Get a surge-protected multisocket if your area is prone to bad weather.

The problem is the MicroUSB port on the tablet has an extra connector so I don't think it will be possible to use a normal microUSB cable with a 12V adapter.

I tried with another adaptor which has the right shape and 12V output and is supposed to be compatible but not joy. It might be the tablet itself but it's weird if it just stopped working overnight.
