Bintoo`s, Kobo Cardiac arrest treatment - ok, take the plastic back off by sliding your fingernail along the back edge and pull the side out a bit, you will see it start to come loose. work at it all around until the back is off. You`ll see the battery in the middle top with a little red and black wire coming off it to a black connector on the motherboard. pull on the battery connector with your finger nail, it will pop off. Take a regular 9 volt battery and with some small straight pins, connect the + to the red and - to the black on the battery contacts of the kobo battery. This is the hardest part, making sure you are connected to the contacts on the battery. hold it on the battery for 2 minutes. Your going to put enough voltage into the battery to bring up the charge on the kobo battery just a bit. after 2 minutes stop charging the kobo battery. press the little black connecter back onto the motherboard (only goes on 1 way). it snaps when it connected properly. plug your usb cable back in and see if the green light comes on your kobo. If it does then leave the usb in for at least 20 minutes to get a good charge, then snap the back on. now fully charge you kobo and sync. if the green light does not come back on, repeat the charge cycle to 2 minutes with your 9 volt. (make sure you disconnect the battery from the motherboard before charging.) good luck. The thought here is your kobo is so dead that it won`t even wake up to charge. I have brought back 3 for 3 kobo`s this way.

I have tried the basic trouble shoot but had no luck, any suggestions? - My kobo ereader screen says, "Please Charge Your eReader" and i have been charging it for nearly 2 hours. I am unable to turn my kobo on at all. I have tried to reset it but that does not work either. :: Ask Me Fast at http://www.askmefast.com/My_kobo_tou...na4017873.html |
This is a common remedy for most rechargeable batteries. It is a common illness for batteries sitting on a self that have gone totally flat and a smart charger cannot detect the battery levels and now registers it as defective. There is nothing wrong with the battery it just has zero and I mean zero volts in it. When you apply the voltage you are pushing a small charge into the battery that will register in the charging circuitry of the smart charger, in this case it would be the kobo's charging circuit, thus allowing the battery to once again be charged. It usually works 100% of the time on my NIMH batteries that are shelved in between extended camera rests.
