If you own a Barnes & Noble NOOK Tablet 7, we have a bit of bad news for you. The company is issuing a recall not on the tablet, but the power adapter that it comes with.
It was found that the plastic casing on the adapter can break while inserting it into the wall, exposing the metal prongs and posing a shock hazard. It might be a good idea to use a different wall adapter in the meantime, or at least be very gentle with the original one.
To get it replaced, hit the source link. You’ll need your serial number to start the process, which can be found on the box, the back of the tablet, in the Settings menu, and on the original B&N receipt. There’s more info in the source link. Stay safe!
