Nvidia today announced a "voluntary recall" of its 8-inch Shield Android tablet. Certain tablets sold between July of 2014 and July of 2015 (the entire lifetime of the device so far) include batteries prone to overheating, and the recall notice says they pose a "fire hazard." Users with affected tablets are being asked to return them to Nvidia, which will replace them free of charge.

To see if your battery needs to be replaced, Nvidia says you first need to update your tablet to the latest available version of Android. Once that's done, go to Settings, then About Tablet, then Status. If the entry under "Battery" says "B01," your tablet is unaffected. If it says "Y01," it should be replaced. Tap the Y01 to launch an app that will guide you through the recall process.

Nvidia says you should only use the affected tablets for as long as you need to back up your data. Tablets sent to the company will be wiped and deactivated.

The Shield tablet is among the more competent Android tablets out there right now—it performs well and Nvidia is fairly good at getting Android updates out quickly, and its $299 MSRP comes in $100 below Google's own underwhelming Nexus 9.
