Hi.
I bought a Himalaya from ebay that cannot be charged through mains charger...
Although it can be charged through the usb cable..
I tried to charge it with its cradle connected to the wall charger and it's not charging. If i remove the battery and put it on the cradle it's charging(the battery only). Also, i tried my blueangel's wall charger and it's also not working with this himalaya. (it should?..)
So...now i'm charging the device through usb...either with the cradle or just a capable usb cable.
I think that there's a problem with the connector of the device...but i wonder why it's charging on usb and not charging on mains charger.
The best solution that i can imagine is to open it...measure the pins with a multimeter and then short-circuit the usb charging pin with the 'faulty' one...
Any other ideas?

Hi.
Thanks for the reply. I have already tried to alter the connections on the charger. I short-circuited pin 22 with pin 13 and it was charging. Altough...when i tried to solder the short-cirtuit i destroyed charger's connector So i'm afraid to solder something on the 2020's side.
Is there a way or special soldering iron for such jobs?.....
My conclusion about himalaya's charging system is that it's charging from pin 13 when connected on usb but it's charging from pins 20,21,22( not sure) when connected on a wall charger.
For now, i'm using a usb wall charger by connecting the usb cable on it.
dear nicktgr15
Its very interesting.
Could you please give me screenshoot of that PIN connect to wall charger ? Which PIN in the himalaya mainboard .. connect to what Female PIN on wall charger ?
My Himalaya 22 pin choped so can not possible to charge on spot.
I can only charge the battery by remove the battery and charge on seperate charger.
So when my himalaya power is over I have to take the battery out on it and charge it on the general charger...
Thanks anyway.

The instruction book tells me to attach the charging cradle to the A/C power source for charging the battery on my 2020. However, it 'appears' to charge without the A/C adapter. Is this an erroneous reading ? I mean, why attach the A/C adaptor unneccesarily ?
Thanks in advance

I think one trickle charges and the other rapid charges, I am not sure of this but making an educated guess.
it can charge using the 5volt 500mA that usb give
but not all pc's can give those 5volts from usb when they are turned off
plus i think it charge slower when it can only get 500mA
Hello Friends,
i made myself a Carholder with Charger and Audio-Connection for my Wizard100. I took a Lm7805 to create +5V out from 12V of the Car Battery. I also took a normal Mini USB Plug, and connected the two wires who leads the Voltage to the unit with my 5V Regulator. When i turn on ignition in my car i could measure the 5Volts at the Cradle and when i plug in my Device the Charging LED goes Red and the Symbol in my Today Screen shows the charging. But when i pull out my Device after a while the batterypower goes down very fast and rapid. Why? Is there any conection that has to be done? How many pins are used to charge the Wizard by USB?
Charging current...
How much current is your rig capable of, the stock charger puts out 1 Amp. I know that the wizard is rather finicky 'bout its charging method. Hope this leads you in the right direction...as for pins, i would think that if it says its charging, then your pin outs are ok. It would most likely be about the amperage
The L7805 Regultaor IC fits up to 1.5A .Thats enough i suggest. Now i´ve ordered a real car charger and put the electronic in my carholder. What about grounding? Is ist allowed to put the Audio Ground together with the charging ground or must I divide both grounds?
Thanks so far for your replys...
hi guys, I soldered a 5v charger's +5v & ground wires to a female USB port, then connected to the mini-usb port of the Atom, external power was detected but it doesn't charge, what else do I have to do to trigger charging? thanks!

Interesting. I've noted similar issues, I first thought it was to do with the power current capacity however I'm not so sure now. What I did find was that if I plugged in the usb plug first and then turned the charger power on (e.g. car charger 850mA) then it would charge. However the original charger worked any which way. Also turning off the screen would result in slow charging even when it said not! Does this help?
There is some problem in oem battry driver, you can google to find the driver hotfix.
sorry for my BAD english..
You must give two other pins short with resistor as i remember. This is in order to simulate USB connectivity, which original charger do.
This is for HP Ipaq rw6815 I have..
more info you can find in below links it's for other devices, but the workaround is the same:

I don't think below method i safe enough, I think it's not a wise decision to shorten your data pins, but obviously work with iphone

I was always wondering how to speed up this unacceptably slow USB charging (If you are in a low signal area with bluetooth ON then the battery is drained far more quicker than the laptop can charge it ending up with a flat battery ). Finally I tested the output from the pins of the wall charger and my Laptop. Even when the laptop is powered off (no data exchange) the USB charging is very slow. The HD seems to send a ~1v pulse through D+ channel when to connect it to USB port (even when powered off the device seems to check if it is a USB data port), but with the charger it does not!, so we need to break this communication.
So I put a thin plastic film over the D+ and D- terminals of the USB cable and voila the device charges much faster..(slightly slower than wall charger - 25% slower, can be accounted for by the lower power output of the laptop USB port, the voltage of laptop usb port is 150-200 mV lower).
While I am typing this my HD has gained 9% charge with screen on!! . Natively it charged atmost 1% by this time with screen off.
Now I am looking for a permanent mod for my spare USB cable hacking off the data lines.
For those in a hurry with nothing but a HD with flat battery USB cable and a computer at hand, worthwhile using a thin paper over the inner two pins of the USB cable on PC side and plugging it in. (You do this at your own risk).
Hope it helps others too. Let me know your experiences.
With my Desktop USB port, charge rate is better than wall charger if you block the data pins. The port seems to be capable of 1.5 amp at 4.96 v
Also ensure that the USB cable snugly fits the mini USB port on HD.
Could this be also the problem why (my) Blackstone doesn't receive a TMC-signal with HyperGPS & iGO8 while charging in my car?
It's a genuine car charger from HTC, so I should say these pins are already "shut" from connection, or am I wrong?
I have a usb cable that is dedicatet for charging. It dosent have D+/- wires. With this cable on my laptop the charge time form about 20% is more than half of regular USD cable..
The cable was supplied with a car BT handsfree.
Regarding the TMC issue Im not shure, Try asking the guys that developed HyperGPS they might know, if not they might be able to fix if they arent aware of the issue
Interesting tip, thanks... I've lost my charger and have been finding it a pain to charge it using the USB port on my laptop.
I cut a small strip of paper from one end of a sticky note, and stuck the adhesive end to the outer flat surface of the USB plug to secure the strip in place. Seems to have done the trick, because the charging light is on and the PC hasn't detected the device. As for how long it takes to charge... will have to wait and see.
Also, I was wondering if there was any difference in charging speed (i.e. when charging via USB normally without using this trick) between activesync and file transfer mode?
I fried my charging port socket (don't ask -- coffee, I think). It smelled burned and the charger tip would get hot in the port. I bought a new charging port panel and properly installed it with the protective film removed from the bottom and carefully connected the ribbon cable. The phone will not accept input through the charging port micro USB, but it will charge on a wireless charger. Could I have fried the connector at the battery through which the plug-in power goes? Is there a separate circuit that inputs current from the wireless charger? Could that explain why changing the charging port circuit panel did not fix the problem? Should I buy a new battery and try that? Diagnostic help would be appreciated.
