Cant charge. got new battery and got new a/c addaptor not charge

Check and make sure the power adapter doesn't have a fuse somewhere in it. Then chk the wattage output of the adapter. Watts should be marked on the adapter.. Now see what the computer requires. Computer info is on the sticker on underside of computer.To determine how many watts the computer needs, Note the amps the computer draws(on label) and multiply the volts(on computer again) x the amps. Answer will be your needed wattage.
Use only the adapter that came with the computer. They may look alike, but there is a difference. Make sure the computer is powered off. A full charge is needed now since the battery was dead. Allow time and don't use the machine prematurely.
Make sure the adapter output matches or betters the requirements of the computer.- Good Luck-Ned

What are you using to charge it? How old is your ereader?
Are you using a usb cable to computer to charge? Or do you have an adapter that goes in the wall socket that connects to your usb cable.
You may need a new usb cable, or depending on the age of your ereader maybe a new battery.

If the computer is telling you that it is plugged in but the battery won't hold a charge the most likely explanation is that your battery is either spent (if it is older than two years) or it is defective (if it is a new battery).

Take out the battery and start up using the mains connection. If it doesn't startup the problem may well be your mains adaptor.

The manual indicates that it should show charging as soon as connected, and takes three hours to charge.
I have found that on some devices, this does not happen, and it takes a few minutes for the device to get enough charge into the battery to start up. This especially from new, or if left for a long while.
Try giving it a long charge, six hours is recommended by some manufacturers, using the same type of battery.
leave your computer on, it won't hurt it, as the USB ports, only supply power when it's on.

If it does not work then, as you have only just bought it, take it back.

check wires on altenator to make sure plugged in @ check battery connections also, new battery needs to be load tested to rule out as bad

yes replace both ,batterry and the charger,thath way youl be shure and the new battery must be charge for 12 hrs ...
and should works fine after ..
hope that will help you
regards Alan..

Sounds to me like a broken connector on the socket on the motherboard.check, ,or a broken wire at the plug end, check, or the like, or the battery is not making contact as you discovered. Meter the PSU, and wiggle the plug, and socket and see if it makes and breaks connections.

Mda Vario's don't charge when turned off, heres what you do.
cut wire off a usb lead the small end strip the red and black wires, put the red wire onto the posative connection where the battery is it tells you what side is posative and negative on the battery, use black with negative and red with posative making sure that no wires touch the other metal strips in the phone, replace battery plug usb into computer and start up the mda and wait for it to boot. once turned on leave to charge as it will charge through the wires connected to the battery, after 10 to 15 minutes plug in the actuall charger and try to remove usb wires without taking battery out. if that is not possable it is ok as the battery should have enough power to start up once it starts leave to charge and always keep some charge in the phone.
