Recently digged out my old Qtek 9000 from the closet, and want to get it turned on again, but i have no battery.. It had swollen up years ago, so i threw it out.
Is there any way i can get the device to turn on again? Plugging in the mini usb charger, and i get a steady red led on the device but not able to turn it on. I tried attaching a powersupply of 3.7v to the + and - min but still nothing..
Any tricks?
Replace battery. It can damage the device severely or worse.
Any swelling is a failure.
Do Not attempt to charge a failed Li!!!
Without the battery to supply enough current, it can not boot. The charger can't sink enough current for a boot up...

Where to find a battery in the EU though?
Don't know. Sorry. Li's have a limited self life too of about 3-4 years max.

You can find or adapt a battery if you put some time into it... depends if it's worth it to you.
I have a 12yo flip top ruggedized phone that still boots
So to get the device to turn on with a another battery of the same voltage.. Should i only need to connect the two pins on each end of the pins on the device ?

If there's only 2 pins, yes. The polarity must be correct!
Soldering to the mobo van be tricky if you're not proficient at doing it. Not the place to learn! The mobo landings can easily be destroyed by excess or prolonged heat. Prolonged is measured in seconds like 1-3 @ 725F with well tinned tip using 60/40 or better 63/37 lead based rosin core solder only. A tin or bottle of rosin flux can be useful.
You may only get one shot at it...solder pad landing repairs are even more difficult.
It wire is used, very thin gauge stranded only and always pretinned.

I read in a thread that short circuiting the battery compartment can help with some battery problems. How can i do that?
From what I understood I have to turn the phone off, take the battery out and connect the 3 battery connectors with a wire between them for a few seconds. Is that what short circuiting means?
um yeah i havent heard that. i'm not sure that is such a good idea though.

I'm not sure that is a good idea at all!!! AFAIK short-circuiting a battery can damage and/or destroy it!
If you short circuit something you increase the current at the end of the short circuit to levels greater than designed. This will often damage the rest of the circuit. I really wouldn't do this.

Hi!
I made big big big mistake. I thought I am able to make the inductive mod and solder it directly to the usb connector of the phone. Big fail! Dumb me...
First everything was working but then I wanted more and tried to resolder the new cable to the very small VCC pin of the usb connector. Puff and nearly the complete pad for USB VCC disappeared :-(. Seems I soldered to hot or to long.
I now have a phone which I can't charge any more. Right now I'm on 30% battery so I don't have much time...
I think there are some possibilities:
1st:
Find out where the USB VCC pin goes and solder a cable from there. Right now I had no luck and I can't measure with a ohm-meter to find an other pad with the same net. I also have no board layout from the pcb. Maybe someone of you can help with measuring or pcb data?
2nd:
I find a temporary solution by charging the battery (i have to of them) manual with a lab power supply and some resistor? Does anybody know the max ampere load for the battery of the SGS? Any ideas for charging voltage and series-resistor value?
3rd:
Is there a way to get a working main pcb for the GT-I9000? Maybe from a phone with a defect display? This shouldn't cost too much since I am also thinking about a new model.
4th:
Will it blend? Kaboom? Burn baby burn? ...
Hope I can get help with this!
Well you need a hardware engineer to answer you and here youll rarely find one.

it is dangerous but possible:
use a precision voltage source of
4.195 V +- 10mV
and a series resistor of 2.2Ohm, 1%, 1/2W
if your batt is down to 3.3V it will start charging with about 400mA and goes up to 4.195 V ( will need several hours, you can charge it over night)
never charge to a voltage above 4.210V !!! your LiIon batt will die !!!
best solution is: go and buy an external charger with a battery (approx. 12-19€ with shipping) on ebay
look for a polarcell 1800mAh batt, like this one
http://goo.gl/Cun7U
it's worth the money, i've bought one and use it since two weeks and am very pleased with it.
But be careful, there are some other batterys from hongkong, which also claim 1800mAh, but they don't have it, i had one too and it measured only 1300mAh.

thanks for the detailed infos.
I already have one of these 1800mAh batteries and my subjective impression was good. The second battery I have is the original one.
I will buy one of these charging adapters. Until it is coming I was thinking about using a labratory power supply with your mentioned 2,2Ohm Resistor and with a Ampere limitation of 400mA. Should be no risk, isn't it? Then slowly rise the voltage until I get the current of about 300mA.
The thing is... I have no spare phone and I really would need it on Monday.
I configured the power supply to 4,21V at 400mA max (current delimiter).
It startet at about 4V and I had a constant 400mA load. After about one hour the current delimiter switched off and I now have stable 4,21V. The current lowers slowly.
I think this should be a save charging procedure?
Im no longer able to recharge my A500. Last charge was two days ago and now the battery is dead and it wont charge. Should be no problem with the charger or cord as far I can see. Any ideas? Anyone had the same problem?

Could be 2 things.
1. Charger is fubarred
2. Battery is toasted
Charger you can check with a multi-meter.
Technically, if your tab isn't under warranty, you can find instructions and pop the back cover off and actually change the battery (if you can find a replacement)
How about giving it a good hard smack on the back as an attitude adjustment?
Did you wiggle the plug when it's connected? (while watching the on/off switch)
As a last ditch effort, put the tab in the freezer for 30 minutes. Freezing cold does wonders for electronic contact points. An old trick for dead hard drives, along with the good 'ol fashioned smack.

The center conductor on the tablet could have broken loose from the PCB. I here it's a common problem with the Iconia.

Yeah, I thought about that also awhile ago (hence the wiggle jiggle and watching the light) Also hear if you're not careful, the jack itself can get pretty loose, losing contact. It doesn't appear to be the strongest of things, but, one just has to be a little careful I guess.
Apologies if I don’t have the right forum lads,
I bought a Pipo Max M1 tablet about 3 months ago. I loved it , a very good tablet.
I bought a second one for my nephew as a Xmas present.
Before I gave it to him I charged it using my own charger a 5V, 2.5mA charger.
Then I took it to him in Greece.
Now when I went to Greece I never took my charger with me, I assume my nephews charger would do just fine.
When both tablets were discharged I used my newphews charger. This charger was a 12V, 1.5mA charger totally different from the one which came with my tablet.
When I used the 12V, 1.5mA the tablets showed both 100% charge in 2-3 minutes and then both discharged in less than 1 minute, clearly something wrong with that charger. Both tablets never charged again and where completely drained.
Now when I came back to the UK and used my charger (which was working from the start) , my tablet will not charge, it will not turn on and the tablet will get really hot when the jack plug is located when I hook it up to the power supply.
Is it possible the tablet is fried because of the wrong charger that came with the second tablet?
Could it be a matter of taking it to a technician and fixing it?
Any ideas guys?
Thanks in advance and looking forward to your reply
I have the same problem with you. They sent me the wrong charger (9V, 2.5A). The tablet was dead after 3 minutes. Now i'm waiting to receive the right charger.
Try to reset your tablet from the small hole in the back side. otherwise, you can try this http://www.slatedroid.com/topic/38865-dead-pipo/page__st__20__p__471674#entry471674

Panospc I have tried the reset button quite a few times but the batteries are completely drained!
Also I tried the method outlined in your link , although i had to cut the red cable and reconnect it but nothing happened.
My worry is that the tablet now overheats where the power supply plugs in.
Did your tablet overheat when plugged into the power supply without charging or turning on? Does it work now?
Thanks for your help by the way

I have only the 9V 2.5A charger right now, with this charger, both tablet and charger was cold all the time after 4 hours of charging. The tablet is not turning on. When I get the 5V, 2.5A charger I will inform you.
If you have a multimeter, try to measure the voltage of the battery, maybe the voltage is higher or lower than normal.

Yes I had the same issue when I was trying to get different adapters to work with the tablet.
I have ordered two seperate adapters from ebay both at 5V,2000 mA which the seller described specifically for the M1. I will post them to Greece and hopefully they will work.
Regarding my tablet as I am no expert, is it possible you think my tablet was fried?Can it come back to life?
A highest voltage adapter than 5V (the 12 V that I used) , do you think it burned the unit?

1. try to change battery.
2. unsoldered the battery from tablet and try to to relive with the correct charger ( maybe cut the cable of charger and connect the right pins to relive the battery)
3. connect tablet with the correct charger without battery to see if your table still lives.

I got a 5V, 2A charger from ebay and my tablet works fine now.
I guess that the tablet has a circuit before the battery that prevents charging if the voltage is higher than 5v. So I think that this circuit was fried from the 12V charger and the current doesn't reach the battery and other parts of the tablet. You have to find a way to connect the tablet to an external charged battery with the same voltage to see if the tablet is alive, I think most mobile phones have a 3.7V battery also.

there are three cables when I open the tablet
1 red
1 black
1 grey
what's this grey cable doing? According to your advise, should I connect the red and black cables to an external 3.7V battery?
I read in a couple of forums that I can jump start the battery...how is this possible? any instructions/procedure?

Hi guys I've got the same problem. I got my PIPO m1, but it didn't switch on with or without charger. I disassembled device and charched battery straight. So, after 8 hours of charching it has just 3.25 volt. And if I connect charger to the unit, voltage on its motherboard is 0.5 volt (battery is desoldered at this moment). It can't be the problem of charger, cause I used several ones (5V, 2.5A).
And! The main point! Stock charger was from PIPO m2 so it has 9V Unfortunately, I noticed it after my first charching tryings.
For now I've got a brick. Have you got any ideas what i can do to reanimate it?? ( Thanks!

SpookyXDA I will follow panos advise today and try to connect the tablet straight to an external 3.7v battery.
Also I will try and find a 3.7v charger and connect the battery straight to that charger and see how it goes!
I have the feeling the circuit board , like panos said above, was fried at a point due to the 12V (in my case and I think the same for you since you used a 9V). If anyone is here has good imagination and creativity on how to overcome and bypass the fried portion on the circuit that would be great!
i can upload a couple of photos if that helps!

If it is impossible to fix, I am interested to buy it because I'm looking for some spare parts.
So basically, the phone randomly stopped charging and when i had picked it up to see why it wasn't charging, it was really hot to the touch towards the top of the phone. Not sure what is going on. Tried different cables. Does the same thing when the phone is powered off. I just ordered a new Usb-C jack to replace the phone inside the phone. Maybe shorting of some sort... Any ideas?
Happened with me once, in my case it was draining after putting a charger. So, I let it discharged fully until it got switched off & then put a charger. It started charging normally.

Did you try with another adapter? Because then we can rule out the possibility of a short circuit.
And, you mean more hot then usual? Because it's a 2A charger it's sure to heat up the phone.
One more thing, if it's a short then there are possibilities of the surge protector getting burnt which is inside you phone. In that case, either, you'll have to replace the entire charging circuit board or maybe just the surge protector (It varies form brand to brand. Hope Zuk has a replaceable surge protector)
Well I tried various combos of power sources and cables. Nothing seems to work. It's been this way for a while. Now I'm just using a backup phone.

The high voltage protector on your circuit board must have been damaged. Take it to a authorized personnel and get it replaced. Nothing else stands a chance and it cannot happen because of a software issue. If it was a software issue then it would be more like there won't be any indication that it's charging and battery percentage shown would be stuck but still the phone's battery will be charging and will stay powered on.

No, no! Your USB Type-C port will be attached to a separate circuit board. The board may also include a mic and maybe a speaker too. So there will be a switch just like a MCB for your house, which in case of high voltage will get get burnt and hence break the circuit. Now just replace that board. Or some manufacturers' design allows just the surge protector to be replaced (Which will save you a lot of bucks).
