My son's nabi dreamtab will only allow us to use the stylus to navigate not our fingers we have tried all the resets and calibrations and still nothing what else can we do?

Try another power adapter for a USB device. If this is the type unit you are referring to, it looks like it has a power/charging adapter as well as the USB cord? Those are pretty much standard with a few exceptions. The cord rarely fails but a power adapter sometimes fails.

eBay shows a lot of available replacements.

Also, make sure the electrical outlet is live. Do other things plugged into the outlet work?

And, if the power adapter has a fuse in it (can't tell from these listings), make sure it is not blown.

There are two types of resets that you can perform on nabi - forced reboot and factory reset. In the unlikely event that your nabi becomes unresponsive, you can easily perform a forced reboot. A factory reset is recommended when slow performance persists or if you want to wipe out all of your personal data and settings from nabi. Forced Reboot: To perform a forced reboot, hold the Power Button down until nabi turns off. When nabi is off, press the Power Button to turn on nabi again. Factory Reset: Caution! A factory reset is a very serious process because it will SYSTEMATICALLY WIPE ALL USER DATA from nabi. A factory reset will return nabi to its original factory settings.To perform a factory reset from Mommy/Daddy Mode, tap All Apps > Settings > Backup & reset > Factory data reset > Reset tablet > Erase everything. Please note: We highly recommend backing up your nabi prior to performing a factory reset. You can back up your music, videos, photos and apps with nabi™ Sync.
