Hi,
my screen of the archos g9 (1ghz, 8gb) is broken.
now i want to use the logic board like a raspberry pi.
i have bought a mini hdmi to hdmi cable.
i removed the battery, so do anyone know if it will work without the battery (by just plugging in the usb cable?)
which pins should i connect to let it boot?
Hopefully someone like scholbert can help me with this problem,
Nick

i have the same tablet as you and my battery still slowly discharges while plugged in if im actually using it. just a thought but maybe youll have to put the batteries back into the tablet
although thinking about it since your not using the screen at all it wont be drawing any power and from what little i know im pretty sure thats the most power hungry part of the machine.
Yeah, but I tried to boot without battery with no success
On some things you need to connect 2 pins to get it working

You can try... but i guess you'll need to tweak your Android system a little bit to make it work.
For example, i found out that Android refused to start up completely without the touchcontroller connected to the internal I2C bus.
Another thing might be the avtivation of HDMI.
Never tried it though.

No, plugging the USB cable is not enough. But you can power it up without batteries. There's no need to connect some pins directly, though it might be useful to similate the NTC. Read on to get it work.
As you know i use my A80S mainboard for experiments and i use a LDO to power the board instead of batteries. You'll need some soldering skills though!

As stated above this won't work.
Please see the attached pic.
I use a simple wiring with an LDO adjusted to 3.8..4.2V and connected this cicuit to the battery solder pads on the mainboard. Completely unsolder the battery wires first.
To avoid temperature warnings i soldered an additional 4K7 resistor at the NTC solder pads.
You may use any adjustable LDO which is capable to deliver at least about 1.5A max. current.
The example in the pic uses the LDO from Pandaboard.
It is adjusted at 4.2V, which is the approximate maximum value of a fully charged LiPo cell.
The datasheet could be found very easily in the web, to get further information.
Happy hacking!
scholbert
thanks for your post, i was on holiday so i couldn't replay earlier.
seems like i am just going to connect an battery then
If i get some money i will try the way without the battery
i can't use the board for something else so this is a nice "hack" project for later
Big thanks

Does someone know if the HTC shift can be charged via the USB port?
This might allow: 1) use of an external power supply via USB; b) hot swap of standard Shift battery 3) Emergency power in a pinch...
Should it be possible?

No
The shift needs alot more powere than what a usb port can provide, so it's newer going to happen
Yup = the charger outputs 12 v and USB is of course 5 v - Too bad WOuld have been cool to hot swap the battery though...
another charging-related question
My SHIFT has stopped recognizing when the external power supply is plugged in: no orange LED, no icon toggle, no switch to the plugged-in power management profile. The battery charges okay, so I can live with it, but it is annoying. I suspect a component in the charging electronics has failed, but am curious about alternative theories, and if anyone else has this problem.

HTC Red light of Death
Guys,
I am a service tech for HTC. I would like to tell you couple of things.
When there is red right, Battery will not charge with the chargers (Electrical or USB). It will flash with Car Charger as the charge is high in Car charger.
If you see Red light..your Battery is fine. there is no point of changing the battery.
There are two IC in the motherboard of HTC. One is the Charging IC & the other one is Power Consumption IC. You need to Change the Power Consumption IC, which will cost around 10-20$.
Dont follow unnessary steps as it will affect your PDA ROM sometimes.
YOur HTC will work fine for ever.
thank you for your answer

Thumbs up HTC Red light of Death
Guys,
I am a service tech for HTC. I would like to tell you couple of things.""
so you said you are working for htc ? if so i suppose you re not allowed to give us some clues about the very specific clio hardware, like the sd card link with the snap vue side..
anyway i think you are very welcome here!
woooooooow ur welcome here defenatly, at least we can pick ur brains with few things, plz plz plz make our shift upto expectations by giving us clues not solution but pointers for making BT and SD work
looking at his lack of spelling and grammer i think he might be a joker especially his last part " YOur HTC will work fine for ever. " erm he would no thats not true if he really worked for them.
tho i hope im wrong and they can get us a shift that works with the odd lil leak of info.

Hello friend,
I am unfortunate I damaged my Shift when power accidentally went in through the USB port thus damaging the power consumption IC in the motherboard. Unfortunately I dont seem to get the replacement part anywhere. You had mentioned that specific part in the post mentioned and I was hoping that you might be able to assist me.
Here is the thread about my unfortunate Shift..... http://forum.xda-developers.com/showthread.php?t=701950
Car power adapter 15-25 for my htc shift is it possible?
Hi to all.
Yesterday I bought via internet a car power adapter like this:
http://cgi.ebay.com/15-24V-80W-Car-DC-Power-Adapter-Auto-Charger-Laptop-/180476771054
But my HTC SHIFT can be recharged with 12volts typical so question is:
CAN I USE 15Volts (minimum output from my new car adapter) to power my HTC SHIFT or is just a little bit more. I suppose max 20% more is just good but not more than this.
I must put a zener diode ... to reduce a little bit or as in your opinion I CAN USE IT WITHOUT PROBLEMS.
Thanks
sullivan2002
Thanks for the idea! I would defenitly put a zener between there just in case. Do make sure you use a high amp zener. I could build a boost converter to get from 5 to 12V but that would cut the amps in more than halve but it could be nice to use an external USB battery to swap my shifts battery. I have 3 battery's so that would be nice. Any idea how much a sleeping shift uses? The converter won't be able to put out more than 200mA becouse of the USB restrictions. Is it possible to keep it from charging when swapping battery? Becose i think that charging uses a lot but a sleeping shift almost nothing(not hibernate).
Guys be very careful when using chargers that are above the Shift's specific power rating. My experience with the Shift confirms that HTC did not think about safety measures when putting the Shift together. I had a small freak accident with the Shift when power entered through the USB port and instead of just blowing a fuse the entire motherboard got fried! You dont want to fry the motherboard coz getting a replacement motherboard is as difficult as swimming across the Atlantic. Ask me how I managed to swim across I will tell you.
So I would advise you to tread very carefully. For me what I did is that I had a 12V, 2A car charger for a different device lying around. I simply cut off the power jack on that car charge and replaced with one similar to the Shift wall charger jack and all is good. Of course you also have to be precise about the polarity. The Shift has several week points that you dont want to mess with
They say that the charger of an EEE PC 901 an the Asus R2H have the same charger as the shift. That is only partially true. The specs on the charger is the same but the shift uses a slightly smaller jack. The eee and the R2H are interchangeble. I have a friend with a 901 and it charges my R2H just fine. Shame becose I have 2 chargers for the R2H and only one wonky one for shiffy.

True it has been confirmed that Shift Charger and eee Pc is one and the same. Only difference is the jack.
http://forum.xda-developers.com/showthread.php?t=502548
So if you have a eee pc or similarly rated charger lying around you can replace the jack and you will be good to go. You can pick the Shift size jack from any elctronics shop. Thats how I managed to rig myself a Shift car charger
Hi new member and new owner of a 4G shift
to answer the OP 's original question of "can you charge off the USB"
it depends on your motherboard, I have a Gigabyte X58-UD4P and with the USB power switches enabled my phone will charge while connected to the USB port
I have 4 PCs set up and my personal rig is the only one that will do this
Now a Lap top is a different story, I would suggest checking with the manufacture
of the Lap top to see if the USB can be used for this function

i charge mine vis pc usb sometimes.
works but a lot slower than the stock charger.
Could you explain if it's necesarry a especial cable or how do you conect the Shift's USB port to a energy usb porwer source?
Guys, the microUSB port on my 101 G9 got broken by an accident.
Looks like It needs a resoldering (and due to double-sided main board it gonna cost some serious $). I removed the port entirely as I dont need PC connectivity.
Is it possible to solder a usb cable directly to BAT-/BAT+ points on the board? Or do I need to connect it to microUSB soldering points to work properly?
//sry for my bad english - I'm from Russia and got hella tired today(
Hi Devl547,

Don't attach the USB cable to the battery points on the mainboard. This will damage your mainboard and battery on long term.
Please look at the area around the broken MicroUSB port and search for a green colored component.
This is the fuse for the 5V comming from the port. You might easily find a soldering point in this area as well.
You should use this as the connection to your cable, nothing else!
If you are unsure, i'll post a picture.
Best regards,
scholbert
Thanks. Actually, I have already soldered a usb cable to microusb soldering points ( nightmare difficulty :3 ).
Looks like it works perfectly, but I think I'd better buy a new Archos tablet next month and use my old one indoor as a internet/video terminal.
Hi. Can you please upload a Picture from the Solder Points how i must solder the 4 wires from a USB Cable? Thank you very much!

Maybe you're able to locate the camera clip on your mainboard and remove it.
It is located near the micro USB slot...
See this post i made long ago (most informations are valid for the G9 101 as well):
http://forum.xda-developers.com/showpost.php?p=28542261&postcount=41
After you removed the clip you should be able identify the fuse as well.
It is a marked component with a "T" on top.
As told before this is the best place to solder some cable for external charger.

I thought I'd throw this out here to whoever is interested in a similar install.
It's been a long while trying to figure out how to get my nexus 10 working otg without draining the battery. So, what I did was eliminate the battery all together and run it with a regulated power supply soldered to the positive and negative pins inside where the battery clip would normally go. Everything ran smooth without any errors whatsoever, then came time to test it all out by plugging the otg cable. what do you know, it worked flawlessly.
I'm able to run a usb hub with 3 flash sticks and 1 ssd hd. Hub must be powered separate with the power plug. This is a perfect setup for my situation since the tablet is installed in my truck and I wasn't too happy with the idea of having a lithium battery inside on hot summer days.
I'm pretty sure this method could even work while keeping the battery installed inside connecting the leads to a double throw relay along with a separate plug that would separate the two power sources.
Testing also passed while plugging it to the pc foe file access and debugging mode.
Hope this helps some people. Don't be shy if you need to ask any questions on this project.
Later
A pc usb port puts out 5v 500ma wich barely keeps the Nexus10 battery level
The ac charger puts out 5v 2amps
I hope your power supply is putting out same amps..

Hello Asylum,
I'm indeed interested in your setup, since OTG+charging is not possible with traditional methods (even pogo cable doesn't work along with OTG).
If I clearly understood, you opened your nexus, removed the battery and directly soldered cables + and - ?
Is it a complex operation ? (in particular to open the nexus and close it without tearing it down).
Do you have a photo of your installation ?
Thank you for your help :cyclops:
LeDuke
I'm also interested in this setup and would love to see pics!
Not to sound like a d1ck or anything, but I have a alternative. Just make a otg cable with a male and female USB ends and just hook up the male end to power lines. Them you can just use a regular USB wallwart to profile power to your drive.
I used this method to run a 1tb external HDD.
Hey all.
I broke my nook tablet's cable accidentally.

It actually is microUSB. I lost my OEM cable (which is slightly different, i think they added a couple pins to enable fast charging) but I use a motorola cable and it works fine for charging. it just takes a ridiculously long time and it doesnt charge while you're using it. unless you have a B&N store around you (which i'm going to assume you don't) you can't really get a new cable. maybe online but i wouldn't do it, chinese cables are cheap, bad, and potentially dangerous

Yes the B&N cables are special, the pins are longer and more of them to tell the nook to fast charge. But as you found out, any micro USB cable can work, just slow slow charge it. And you can't use the device and charge at the same time as you will be using more energy than is being supplied. Oh another help is to turn off wifi when charging from USB, having that on will have the device charge slower as the the radio will be accessed occasionally.
I did find this http://www.amazon.com/dp/B00FMMPDT4/ref=twister_B00FMMOSYU the connector looks longer than standard USB so perhaps it would work. I can't say for certain of course. I also saw used Nook Tablet power adapater/cable sets on amazon as well (original OEM). And a final suggestion would be to get one from ebay. I have seen a few there as well.
I am surprised B&N won't ship the cable at all. Seems like they would want to sell/move them. I was looking at them the other day and you can see how the V2 is from the photo. The connector on the nook side is not long and easy to snap off/apply stress to like the original. http://www.barnesandnoble.com/p/nook-color-new-cable/27359237?ean=9780594459453
If anyone ever gets the KS cable, please post so we know it works for sure. It looks like it will, and I may even contact them to see. I think the biggest problem with the original nook color/tablet cables was the nook connector was too long/straight and easy for people to break (that and the connector wasn't reinforced like it should have been).
@skepticmisfit
I see some sellers from china who can ship the cable to my local address. I'll see if I can get a good one.
Also, keeping the cable connected to the laptop's USB 3.0 port is useful. :good::good::good:

No. It seems i don't need a nook's stupid cable at all. The tablet gets charged on usb 2.0 port too. I am using the CM11 nightilies ROM and gapps minimal, that is efficient in terms of battery usage.

Does it fast charge? I thought the NT would only fast charge if you use the B&N cable? Or is the fast charging lock to their cable only work with the stock ROM?

You don't really need a replacement Nook charger, any 5V 2A USB wall-charger plug and a regular micro-USB cable would do although it would take a bit longer to charge.
While Digi is right, there are official Nook cables and chargers (refurbished) on ebay at the moment. You can still get the cables from Barnes and Noble but I don't know if they will ship to India or not. I would try searching for "nook tablet" on ebay.
Also if you are going the generic charger/cable route, be sure to have the screen and wifi off while charging. If you have the screen on, it will discharge faster than you can charge it.
One final note, even if you are going to get a official charger (which I would recommend as it is so much faster) it would be wise to plug it in to a generic cable/charger combo for now. It is NEVER good to leave the Nook laying around with a dead battery. It will kill the battery in short order. And it is harder to get a Nook Tablet going again with a generic charger if the battery gets too low (shuts down on you).
Apologies in advance if this has already been asked and answered.
I'm interested in using my USB-powered DAC to send an optical audio signal into my digital signal processor in my Jeep. The obvious problem I face in doing this is HEAVY battery drain.
I used to run a 2nd generation Nexus 7 tablet as my head unit in a previous vehicle, which could power by USB DAC while charging with the use of a Y-cable. This doesn't seem to be the case with my S9+.
Do any of you know of a way that I can achieve this with the S9+?
Thanks in advance for your help!
Just thought of something...
I'm guessing I could use the DeX dock to charge while using the DeX's USB port to power the DAC. That SHOULD work. Alternatively, perhaps I could wirelessly charge the S9+ while powering the DAC via OTG. Either application (if they work) would only prolong battery life, as I imagine the drain would be greater than the charge.
Anyway, still wondering if there's a way to get an old-fashioned charge while using OTG with a Y-cable or similar (powered USB hub?).
Bump. Curious if anyone has had any luck with this. Thanks in advance!

i dont think youre going to have much, if any, luck on this man. USB type C is kinda weird like that. There isnt even a jig for type c like there was with micro. Im following this one too.
There are aftermarket devices available that provide you the capability of using a USB along with a charging port and a HDMI output. I have tried it myself using a mouse and charger while connected together with the phone..... You could give it a try. That should work and is inexpensive too. I bought one and still use it sometimes for my Dex needs.
