Could anyone confirm for me the polarity on the power socket - central pin -ve or +ve? I have an Archos 70 but suspect 101 is the same
...and answered my own question. Centre is positive (it's written on the back of the charger). Apologies for stupidity
I can also answer your question: centre is positive! It's written in your second post.

Yes you're right
its the same charger as the Archos 7/8 HomeTablets too old stuff..^^

Im sorry the title seems vag, but here is the thing, I wanna know from anyone what the voltage is for the tablet ( Archos A101IT ) and also when its Completly dead does the charge lite come on? If not will the system start its self? Im asking because i can get one almost new without a cord but im afraid to get it because they will not take it back if it doesn't work at all ( asking 150 ) Let me know so i know what to do!
thanks.

The device could be charged with a standard 5V wall-charger.
Refering to the Archos FAQ, a current of 1A should be sufficient for charging.
You will need special 3.5mm DC adaptor-plug to connect to the device.
Personally, i use an old IPAQ wall charger (5V/2A) and soldered the DC-plug myself. Make sure you use the right polarity.
The device will charge autonomous, even if it is bricked.
So the decision is up to you if you buy it.
On my device there'd been some hardware problem i was able to fix, but i needed professional equipment to do so.
Under normal circumstances the gen8 series are hard to brick, but you never know.
The most common hardware issues are cracked screens

Anyone had any issues with the a/c plug not seating correctly? I have two separate chargers, and they both need pressure applied (pull slightly toward the direction the screen is facing) for the 70 to know it's plugged in. More often than not, it runs itself dead even though it's plugged into the wall. I sent in a support request to Archos a few days ago, no responses yet.
if u have to press/pull the plugs in any direction for it to work - it most time a broken solder connection inside....
so u have the option to w8 for archos (wich will propably not fix it for warrenty - since those defects are most time effected by outside force) or u can start disasembling your device and get a soldering iron
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

Replace battery with LDO regulator

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!

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
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,
first: Your english is perfect, no need to worry.

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!

Hi scholbert!
If you still read this, I'd really appreciate that picture as my micro usb socket came loose and currently I can't charge my Archos G9 101 Turbo.
Thanks,

I'm still using my Archos tablets, but i'll need to find my disassembled one to make a better picture i guess
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.

scholbert
The metal sheath that the charging cable plugs into and is connected to the motherboard (with 4 pins) has detached which has made it impossible to charge the unit. Archos wants to charge me more than the tablet is worth ( I actually got it last February as a gift), and no repair techs in my area can fix it (pins and connectors are too tiny). I thought about maybe using a charging mat but can't find one for the Archos tablet. Doesw anyone know if a mat would work? SO...I have a perfectly good tablet that cannot be charged. Can anyone help? Would anyone like to buy it for parts?
repair
The battery inside archos tablet are not designed to charge with a mat.
The only way for you is to repair the mainboard.
