You neglected to provide the age of the tablet. If it's a couple years or older your battery might be on the way out. They don't last forever and some of them aren't of the best quality to begin with. Charge it all night long. In the morning when you turn it on if it still doesn't work right be sure to check the battery level with the A/C adapter unplugged. The level indicators are based on the voltage. If the voltage doesn't come up to spec, it might show less than 100% charge even when charged overnight.

The wi-fi problem could be battery related, too, as wi-fi is a radio transceiver that sends as well as receives signals. Wi-fi doesn't work so well if the transmitter produces a weak or intermittent signal.

Does it use an AC adapter or a USB cable to charge? The AC adapter or the USB cable could be bad. Try another cable/adapter. Does the tablet show a lightning bolt on the battery icon when you connect the charger or nothing at all? Does the tablet power up when you are connected to a power source? If the answer to both of these questions is yes, then it is probably a bad battery or charging jack. If the tablet is under warranty, contact the store where you bought it or the manufacturer. If it is not under warranty, try an independent cell phone store that might be able to open it for you and see what type of battery you need to replace it. Get the battery pack model number, size, voltage and maH rating and search for a similar battery on Ebay.

If it\'s only two months old it may have a defective charging cable or adapter. If it\'s a new purchase and you can return it. To check to see if it might be the adapter and not the charging cable you have a few cheap ways to test this out.



General charging recommendations.



If you get power leave it on charge at least 3+ hours. This is the minimum time required if the battery is totally drained. If the Nook turns itself on during this process manually turn it off. The battery charges faster and more deeply if it\'s truely powered down. Charging more than 3 hours won\'t hurt it. In fact some manufacturers claim leaving thier products on charge for an additional hour after the charging light glows green is good as it leaves a slightly deeper charge on the battery. Also I believe leaving it alone for that hour allows it to cool the battery. Most manufacturers also recommend tottaly draining the battery at least once a month and then fully recharging it 1+ hours after charging light is green. They claim this helps the battery maintain a healthy charge and extends the battery life. Simply disconnect any charging cables, turn the unit on and just let it set. Don\'t touch it peroid just leave it alone until it turns off because the battery is totally drained. Then just plug it in and leave it. Only if the unit automatically turns itself on do you manually turn it back off.



Well that\'s about in in keeping the battery life and charge at its maximum.



If your AC power adapter has gone south there are only three ways to get around this. 1. Purchase a generic AC to USB adapter. 2. Purchase a genetic DC to USB adapter. Most of these can be cheaply purchased at most drug stores ect.. these days. You can even get DC to USB ones at dollar stores such as Dollar Tree. Good way to maintain your battery if your AC one goes south or you lose house current.



One other way to charge your battery is to plug the USB cable into your computer. Some manufacturers don\'t recommend this as this more often than not doesn\'t fully tank up your battery.



You can also get replacement charging cables at the same place you got the adapters. Places such as Walgreens, or CVS often have these at around five dollars a pop.

Hi. I also had that problem whenever I let my Samsung tablet battery run totally flat. It takes some time before the tablet starts showing a charging indication on the screen when plugged into a wall socket. You need to leave your unit overnight to charge, then try to switch it on the next morning. Press the power button for at least 3 seconds. I don't know if this will also apply to your unit, but give it a try.

you had to plug it in the charger for a while and then you hel the power button for more than a minute

if it not work hold power button and volume up for 20 sec.

i see that you are using a universal power adapter, do you have the voltage set to the proper voltage that the unit requires?

I have one of those radioshack universal power adapters.

Based on the fact that it says that it can charge via USB, you would need to have it set to 5 volts. if you have it set to anything different, you are risking damaging the unit.

Try a different power adapter as an alternate step. If that doesnt work, come back and I will try to help you further.

Clean connections at battery source. Check adapter and plug of adapter for power and clean terminal of adapter and where it plugs into unit also.

If this is under warranty take it back. If it isn't power the unit on with just the battery powering the unit. When you see the Windows splash screen drop the battery out after the screen goes black put the battery back in and press the power button. This should bring up the on screen menu telling you it failed to start or shut down correctly. Select, Boot in Safe Mode and see if the system will power on. If that fails you need to do a system restore. To access system restore options power the unit on and press and hold the F10 key, this will bring up the restore Windows options. From that menu select to restore your operating system. If that fails you will have to do a complete restore to factory default settings. If that fails you will have to replace the hard drive.

Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time. Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced.
