Some Nvidia Shield Tablets built between July 2014 and July 2015 could pose a fire risk. The batteries in the affected tablets can apparently overheat to dangerous levels. As a result, the company has issued a recall notice. The recall applies only to tablets that show a battery model of Y01 on the About Tablet screen in the Settings application.
If you own a Shield Tablet, Nvidia recommends that you make sure it's running the latest software update. The company will send a notification to affected Shield Tablets which includes the tablet's serial number and instructions for filling out the recall form. Once owners receive a replacement tablet and turn it on for the first time, it appears Nvidia will remotely disable the affected device, so be sure to back up your data beforehand if you're an owner of an afflicted Shield.
