Introduction

You need a thin tool to get the back cover off. If a plastic opening tool is not available, a guitar pick works just fine. Use caution when removing the back cover and inside parts.

Did this tablet have a speaker soldered onto the mainboard? I'm working on a Nextbook 8 NX785QC8G as well, and the first thing I saw was that there's a speaker held together with three screws and a bit of adhesive to the back cover and its cables are soldered onto the motherboard. I don't believe that I ruined them, but they do look a little loose.

The first Nextbook 8 model NX785QC8G tablet I bought, was from Walmart sometime mid summer 2014 AND it was running Jelly Bean. Battery lasted maybe 5 1/2 months; didn't realize tablet had 1 year warranty if I registered tablet with copy of receipt and have it fixed.

So, bought another Nextbook NX785QC8Gu several months later; this one came out running KitKat. I registered online and copied my receipt, which was uploaded to them. Still have had several problems with battery...ie.turning off before completely discharged, not charging in a reliable steady manner,and more. The Li-ion battery(what I thought it was), being 4,000 mAh, should be more than enough to last quite a long time....No web surfing, d.loading or game playing...just YouTube video watching. Can this battery be changed out? The first nextbook the battery quit in, I took it apart - the battery was glued & the speaker wires were attached just as you described.

Image 1/2: When working with electronics, it's important to choose a tool that's ESD-safe to avoid accidental damage to the device.  The regular black nylon spudger or a plastic opening tool should be used whenever possible.

Why the five wires when most batterys have 2-3. What do the five wires do. Thank you

  • Using the flat end of a spudger, carefully work the spudger under the battery, lifting it off of the device.

Also some models have the battery glued down. You'll need to work on trying to pull up the glue work in a circle going around the edge of the battery it was tough you can damage your battery if you do not do this step carefully
