I buyed archos 70 from emarket in england a week ago , after I have installed froyo 2.2.1 e some other apps all worked fine , perfect ,until yesterday , because my archos don't recarge battery now. The charger work well (there is green lamp ) but don't charge the battery . The battery is completely down and is impossible turn on the archos. I don't know if is a problem of software. the firmware is 2.0.54 Any suggestion ?

What state is your Archos in when you attempt to charge it? Is it in one of the sleep modes, or is it truly powered off? (For the system to be turned off you need to hold down the power button for 10 seconds).
Some people have thought there system was turned off, and wouldn't turn on, but in quite a few cases the system was in deep sleep. Some people who have thought there system was dead, and not charging have found that it was actually charged but not reported correctly by the charger light and had either entered deep sleep or crashed.
After the system is turned off (by holding down the power button for 10 seconds) you're supposed to wait 10 seconds (not pressing anything) before attempting to power the system on again. Most people only need to press the power button once to get the system back on again, but a few have had to hold the volume up button while pressing power then release the power button (while still holding volume up) to enter recovery mode.
Unless you use (or plan to use) root for your applications I recommend you update to the 2.0.71 firmware Archos released on December 16th since it fixes quite a few bugs that existed in the 2.0.54 firmware.
I have the 70 and in the very cold weather in the UK recently I've noticed that it needs to be warm in order to charge. Put it close to a heater for half an hour or so and then plug in the charger. It charges best in Deep Sleep and Aircraft modes.

incredible !!!!!!!!!!!!! you are my savior (i don't know if this word is correct, i'm italian) ...................... WORK !!!!! after 3 days that I was making 1000 proves , after putting my A70 over the heat (5 minutes ) finally rework . thanks nspur

Anyway, that's pretty weird solution. Interesting to know for future reference.

I'm at a bit of a loss here..
Instead of powering on, the battery light goes *blink* *blink* *LongPause* ..
I have a (3 day old) Archos 101 and updated to the most recent software when it I first powered up the device. I probably drained my battery yesterday when I put it in the night stand drawer while Aldiko was trying to import a fresh ePub file..
When I turned it on this morning, it blinked once and stopped. When I plugged in the charger (figuring the battery was drained) the "blink blink longpause" started. Long pressing the power button stops the blinking. If the power is connected, the power light burns, so I figure its charging. If its not on power, the power light doesnt burn. I tried the "Hold + while powering up" to boot into recovery but that doesnt change anything.
The Archos FAQ said something about charging the battery, but its been charging for about 9 hours now and the device still wont turn on.. (Green light still burns continuously while charging, not when disconnected) My XDA forums search didnt turn up any results..
Anyone got a clue what this means, what I can do or whatever? Tnx
Maybe the screen froze. Try resetting it by holding down the power button for ten seconds or so. If you're charging it at the same time, it should boot right back up after the reset is complete.

Yes, I tried that :/ That's what I meant by long pressing the power button. It changes the blinking pattern to just the burning power led..
Thanks for the tip though!

Give it another shot. Disconnect the plug. Hold down the power button for a little over 10 seconds. I would do like 15 in my head. Wait a few seconds after that and press the power button quickly once. If you get the steady green light just wait. Dont keep pressing it. You should eventually see the Archos splashscreen. I have had this happen on several occassions when the system has been idle for a while with the screen off. Hope it works.
Ok; I did that.
Except that when I push the power button that last time to have it boot up; the power light just flashes once. I didnt touch it to be sure and it doesnt start.
When I plugged in the power supply after that, the *blink blink longpause* resumed.
When I hold down the power btn now, it reverts to continuous burning green power led.
Its been charging for more than 24 hours now.
This sounds like what happened to mine. it happened after about 3 days, too. I finally got my replacement the Tuesday before Christmas.
If you get it powered up, get your stuff off & clean up your personal info (something I wasn't able to do.
From my post on AchosFans Forum:
For several days my Archos wouldn't take a charge. I didn't think anything about it the first day...stuff happens. After using it the next time, not really thinking there was a problem I plugged it in (and of course it turned itself on again). So this morning it only had 8%. I messed around a few minutes before work resetting it & such - checked setting>about>battery stats and it said "charging" and 0% battery. When I came home this evening it still said "charging" & 0% battery. It then shut down (with a not-normal screen flicker) the first time I unplugged it (hoping to cycle it or get lucky) and it is now a brick. When I plug it in now the charging light did a fast-double-blink and it it remained dead.
I called Archos & they told me to send it back. She didn't ask for much info before telling me to send it, which I took to mean that it is a known issue.
Same happened to me
The same has happened to me after the archos 101 drained its battery fully. I think the firmware has a flaw where it lets the archos drain its battery too far. In that state, hooking it up to the charger wont make it start charging all the time.
I had the blink-blink-blink problem also, even after it had been on the charger for hours. Finally it started working (and charging! )again after lots of 15-second Powerbutton presses, some in combination with Volume Up or Volume Down, and some with and some without the charger connected. Suddenly it turned on (showing 0% charge in the Settings, Information panel indicating it had fully drained and hadn't been charging in the previous hours) . I advice you to keep trying pressing the Power button 15 seconds with the charger connected, and experiment with pressing it in combination with the volume button, followed by a short Power press to boor the Archos.
In the mean time (till a new firmware comes), i make a habit of not fully draining the Archos (i will install Tasker to let it shutdown at 10%) , and checking if the green led comes on after plugging in the charger. Only when the green led is on, it's really charging. And it should start blinking after a few hours to indicate its full.
My wife has a chinese android iPad clone (a Flytouch II) and guess what? It's also picky at charging and turning on.
The Gravity reply had me scared (tnx though) but I'm glad to report that pwhooftman's post helped!
I plugged it in, put a movie on and started trying to reset/start it. It happened reasonably quickly after that.. I pressed the power button while it was off power, the power led flashed once as before. I plugged in the power. The green light lighted up. I pushed the power and + for 15 seconds, and pressed the power button once shortly. Unlike the other times, the blinking pattern didnt start and the green light kept burning. Hopeful, I put it down and waited - as the FAQ said it would start when it d charged more. Finally after a while, I pressed the power button and it booted. Not exactly exact science, but Im just happy that it works again :/
I guess the "blink blink longpause" means something like "I know I've got power but I cant seem to load my battery" - Archos should have this info in their manuals.
Thanks guys

Nice to know I can scare people...and it isn't Halloween!
I tried everything I could think of to get it to take a charge, with no luck. The problem I had with mine was the times it wouldn't take a charge BEFORE I had drained it - that is why it got drained in the first place.
I hope it was only mine!
He s at it again. Drained to 3% and now it wont charge anymore. *sigh*
except he wont even do the blinking anymore now.
Seems to be a fairly common issue with these tablets :/
Same thing was happening to me too. Dunno if this will work for people, but here is how I fixed mine.
Hold your finger on the power button for 10 seconds while the blinky light is on. This should stop the light completely.
Then plug the charger in. This gave me a continuous light rather than a blinky light. Leave it like that for a couple of hours and then try powering it on again.
Hope this works for others.
Had this happen to me once so far. Seems to have to do with it going into a sleep state or something. If I leave it for long and the screen turns off. Sometimes it won't come back up without first holding down the power to shut it down (even though I can't see anything on the screen) and then waiting to boot back up. I had to plug it in, get the steady light and then power on and it worked.
OK, I know this sounds weird...
But what's the temperature of the A101 like?
I had an identical problem a short while ago, and a forum post suggested that the tablet could be too cold. I thought it was a total shot in the dark, but I wrapped the Archos in a quilt for a few minutes, and amazingly enough, it popped back into life with the charger plugged in, and has been pretty fine since then.
To be fair, it could be one of three things: (i) temperature is the issue, (ii) coincidence, (iii) a bad connection in the pins/socket of the adapter input on the Archos 101 which just needs 'jiggling.'
I have also noticed that if I charge the Archos while it is in standby, I never get more than 92-94% battery. If I shut it down, plug in, then shut it down again when it restarts on power supply insertion, I can usually get 98% battery, at the least, sometimes 100% battery.
I agree, we shouldn't have 'quirky' devices, or have to wait for firmware to fix them, but other device makers have had similar problems in the past with battery reporting, until appropriate firmware fixes.
it happened to me last night frustrated the heck out of me couldn't get it to turn on no matter what i did, so i took it back to pc world and the guy said
"what would you like to do, out of curiosity do you like it?" I replied no and he said "then ill refund you"
i then paid the extra on a galaxy tab and not looking back the archos was a complete pile of sh!te! I almost cried when i turned it on and spent the next two months convincing myself i actually liked it.
its woefully made, cheap and tacky, screen is pathetic and the memory appalling.
i know its cheaper than tab and iphone but for 270 it should still be fit for purpose and this is not it's the worst gadget ive ever owned by a long long shot, i didn't even show it off at work because i was so embarrassed at how bad it was.

So, how did the story end?!? Did it survive?
Ok...
I kid you not, i've tried warming the archos up with a hot water bottle for several seconds and that did the trick appearently...
Had the same problem.

HERE is the FIX ! I am on my second A-70/250 - my wife has the 8gb version, and I thought the 250gb one was simply defective - evidently, this IS a known issue, but it can be fixed, and I sent back my other one without reason
Anyways, no more pity party for me, here is the fix - if you have the flashy-power light dealio going on, plug your Archos into the power adapter, plug the adapter into the wall, and plug in the USB CABLE to the Archos, and to your PC - the Archos WILL pwoer up, when it does, it asks if you wish to mount the USB to copy files, select, "YES" and let it sit and charge ! Now - the REASON it does this is VERY simple, and it kills me to admit that I was killing my tablet all by myself ! Disable the "never off" screen thingy - set it for 10 minutes - (settings - display - screen timeout). Go into your power settings as well - (settings - power management) and make sure there is a checkmark in the deep sleep area ! THAT IS IT ! You are fixed ! Dang... I REALLY wish I would have found all this out before I returned the other one - I had SO much stuff loaded on it ! GAH !! - SenKat !
I got the same problem yesterday, it kept blink blink and could not turn on. After 5 hour charging, I warmed it up by hair dryer and suddenly it's on. Crazy amazing! Hahahahahuahuahuahua.
Temperature is main problem. Try with your hair dryer!!! Heheheheheh
Its sounds unbelievable, but low temperatures are indeed a cause.

my a70 had this same problem, left it rest a whole night, then plugged it in to usb and power (usb 1st) and it booted up, hope this helped
When the power button is pressed, the screen goes off and then turn back on.
I noticed that if I insert the USB charger and I press the power button, the screen goes off, and after taking out the USB charger, sleeping mode works ok for a while.
Some times, I have to try more times to insert the usb charger and press the power button to make it to work.
I noticed when the phone is working in this weird sleeping mode, the battery is discharged very quickly. (a well charged battery is discharged in less than an hour!)
Thanks for any help.

Backup your data and do a hard reset. If the problem persists, consider repair service. This sounds like a hardware issue.
next time check where you are posting, you posted in a Rom Develop section, you should have posted this in the general section.
Sorry, I will more careful next time.
thanks.
i have same problem here in Thailand.
in windows i can't go to sleep mode screen keep always on ..... except charge battery or connect USB to computer. but some time it just automatic wake up again .
but later i found in ANDROID which i run from SD CARD it can put screen off ??????
it run "ANDROID" perfect with any rom and any radio rom
if it is hardware issue. why android is just perfect ????

Hi! Reposting (sort of) from the official lockups thread, but since my issue might not really be related to ICS I thought I might ask for help here instead:
Ok. So I had my Prime docked the whole night, not charging. This morning I checked for mails at about 8.00am (dock battery > 90%, tab battery > 80%) then wanted to check again at 10.30am and it was just turned off.
I tried to turn in on again but it wouldn't show anything, not even a short vibrate or something. The only thing that still tells me there is any life is the small LED in the power button that blinks twice when I plug the tablet to the power cord or when I hold down the power button.
I've already tried basically anything I could find on the interwebs, including:
- Reset button in hole with a paper clip; pressed it only for a second, for 5 seconds, 30 seconds, you name it
- Power button for 1,5,30 seconds, 3 seconds afterwards ...
- Vol down + power button for 1,5,30 seconds ...
Still nothing. Left it on the charger for now though the LED doesn't show any sign of charging. Power supply does work on the dock where the LED turned green because it's obviously completely charged.
Did I miss anything? Did I get the .13 firmware overnight without me doing anything and now it just wouldn't wake from sleep? Do I have to send it in?
I want to add that lockups got more frequent during last week but I could always boot again after a few minutes OR when I plugged in the power cord, even though the battery wasn't nearly dry before the lockup.
Read: I didn't have reboots, I had crashes that felt like an overheating issue known from the PC world but those crashes NEVER happened while charging, no matter what I threw at the tablet.
Edit: tab was in power savings mode.
Edit 2: For what it's worth - C1 serial number, 0215 tablet, 4.0.3, .11 firmware (at least yesterday), never rooted/modded/whatevered.
Edit 3: I just realized I made this thread in General instead of Q&A ... Can this be moved to the appropriate section please?
Nobody? Another user had this issue once and after 5 hours of charging his device just could be rebooted. I've been charging for more than 7 hours now and still no vital signs.
Has anybody else experienced this?
Unfortunately the situation sounds pretty bleak to me.

Thinking a battery pull
after reformatting /dev/block/mmcblk0 to fat32
i got
Code:
cant mount /sdcard
from CWM. CWM doesnt like fat32 i guess.
but then i stupidly did factory reset (on stock rom) which made me lose CWM.
so my TF201 now doesnt register with ADB and FASTBOOT, yet it does go into FASTBOOT mode. It also shows up in device manager, so its not a driver problem. Therefore its not a brick IMHO. i have been switching between mac and windows.
Currently my solution is to drain the battery. im hoping for the best. but also thinking of a battery pull. is this worth the effort? Do you think that will work?

Hi this may be related to the problem I have had. how long did you hold the power button down for? when I had this I too thought that it was terminal but I kept the power button held down for about 20 seconds and then it came on.
There have been a few threads about this issue and since trying the suggestion on there I've not had the problem any longer.
this worked for me :-
goto Settings > ASUS Customized Setting > BATTERY SAVING and uncheck MobileDock Battery saving mode. credit to SimonSaysDie for the solution.
Good luck
Tab 10.1 wouldn't power up this morning even though I'd had it connected to mains power overnight (approx 12 hours). When I plugged it back into the mains power, the battery indicator on screen showed 100% - it powered up (still on mains) and started working beautifully - but, as soon as I unplugged it from the mains power. Black Screen and no life at all. Tried to power up again - nothing. Plugged back into mains - shows 100% battery life - powers up and works fine. Repeat above as many times as you like but it just wont work on the battery. I've tried:
* Holding down the power but for 10+ seconds - nothing
* Holding down the power but for 30+ seconds - nothing
* Holding down the power while touching the screen with on finger - nothing
* Holding down combinations of the power button and/or the Vol up/Vol down buttons (lots of different sequences as recommended by different forums) - nothing
It wont boot up into bootloader mode or anything....
Mains power = fine
Battery = nothing
It was all working fine yesterday morning and now it's toast!
I have noticed that it only works on mains power - it won't work simply plugged into the PC
Any ideas? 'Coz I've run out.... :crying:
Dial *#*#4636#*#* and under Battery Information, you will know whether the battery is the culprit or not. Battery Health should show Good.

Hmmmm... it's a tablet (Galaxy Tab 10.1) and doesn't have a phone, so I don't have anywhere to dial from...
Sorry for my assumptions! I assumed because I can make calls with mine, that you also could. Anyway mine is the 3G variant of the same 10.1. However, it is rooted which means I do not have the same limitations you have. I make regular calls with it and is currently running on Android 4.3.1.

Definitely sounds like an hardware issue, you can try downloading an battery information application from the play store to see if it reports things like a temperature or voltage. Maybe the battery cable somehow got disconnected and you can repair it by opening up the tablet...
Can you 'over charge' these devices?
I'd had it on charge for a couple of days. That's when I noticed the problem.
It's now been sitting around for about 4-5 days powered off and last night I pushed the power on button and it burst into life with a full power on cycle (so it wasn't sleeping).
But, the date and time had been reset - back to some date in 2004 and 00:00 hrs.
Something seems to have gone 'bump in the night' and brought it back to life.....

OK....so it's happened again.... :crying:
Left Tablet on charge, now it won't power up unless it's connected to the mains power.
Last time I had the problem it suddenly recovered (apparently all by itself) and it worked fine for ages. I re-charged the battery quite a few times, but suddenly, it's decided to stop working on the battery again.
In the last month, the battery goes up to 100% and drops down again. I usually recharge the tablet when it's around the 10-15% level. I don't do anything odd or extraordinary....
I don't beat up or drop the tablet, it's well taken care of...
Has anyone ever heard of this before?
Well, I've replaced the battery. Charged it fully and.... no change!
While the Tab is plugged into mains power, it runs like a charm.
As soon as I unplug it from Mains power (with the battery showing 100% full charge), it powers off immediately. No shutdown, just a black screen.
I'm now certain it'll need to go in for repair as something inside has broken, but does anyone have a better understanding than me (not very hard!) of the internals of the Tab and where the problem may lie ???
Cheers
Long story short. Another Z compact down. This time it's my Z5C.
Unrooted Z5C E5823. I flashed some marshmallow from xperifirm (build 32.2.A.5.11) some 8 months ago...
Description of events:
Just finished texting. Turned screen off. I go to turn it on again but the phone turned off, because pressing the power button doesn't do jack. Long press it and doesn't turn on.
... great.
Volume down + power button and it turns on after 3 vibrates. Battery level plummeted from ~70% to 20%. So I just put it on a wall charger and wait.
Some 20 minutes later, I'm surprised to see that the phone is still at 20%. So at this point I'm sure something is very wrong and I start browsing for solutions. Nothing worked.
The only thing I didn't do is a factory reset. But I seriously doubt it's a software problem.
So I say "screw it" and I unplug it from the charger and start using it normally. At some point the phone turns off on itself so I have to do the volume down + power button combo again. But this time, alas, it doesn't work either. So I try the little yellow "off" button on the SD bay + holding power button. This time the phone vibrates 3 times. Then I turn he phone on again. But this time it turns off after some 40 seconds. Then it began a short power on/off cycle and then remained off. Won't turn on. Like if it was hard bricked. I fiddled with the yellow off button while plugged in on the charger and it turned on again but still won't go past or below 20%. Ever.
I remove it from the charger and go home from work. Phone is unresponsive. PC doesn't recognize it. No key combination works. Charger and key combinations don't do jack. But THEN out of the blue, I sense 3 very faint vibrations (i just kept trying to power it on, I wasn't giving up ) and now the phone is on again. Battery at 20%, obviously. Service menu doesn't have a battery test anymore. How convenient... Battery usage menu is always the same when I turn it on. PAst history is gone, app % use are all the same ratios.
I'm trying to backup my data now. But at the meantime. Phone is on and still stuck at 20%.
So, is the battery dead? Wth is going on?
i have smailer problem
my phone wont pass the 90% . also after factory rest (stock rom\kernel\no root\lockedBT)
still, im not sure 100% is my batt i think is started from android 6 (now im at 7)
also my phone wont pass some voltage also (4.300) was 4.350 when the phone was new with 5.1.1

hi,
I had same problem somes weeks ago.
try flash new rom, phone stuck at 20% but seems to have same battery's autonomy .
after a week I changed the battery, now all works fine
I think this is the lithium controller that is dead not the battery itself .
Battery and turn off problem
My Device have charge (50,60,70 or more), unnexpected it show 0% and turn off.
Hardware problem maybe ???
