Nextbook 8 Battery Replacement

はじめに

You will need a thin durable tool to get the back cover off first. A guitar pick works well if you don't have a plastic opening tool. The parts are very delicate, so use caution when removing the back cover and inner parts.

Use the plastic opening tool to remove the back cover. Carefully slide the tool between the front glass and back cover.
Slide the tool along the edge to work the back cover off.
It helps to have an extra tool to stick in the gap and keep the back cover separated from the glass as you slide the other tool.

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.

Start on the side opposite the Power and Volume controls. And try not to push the Power and Volume controls on whatever surface you’re using to stabilize/hold the tablet during removal of the back cover. Otherwise you will turn the tablet ON, or get it into DNX Mode.

手順2

Remove the tape covering the motherboard.
Remove the silver tape holding the white ribbon cables to the battery.

手順3

Use a spudger to carefully disconnect the battery connector from the motherboard.
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

Use a spudger to lift up the black bar on the two ZIF connectors located above the battery.
Pull the ribbon cables out of the connectors with tweezers or two fingers.

手順5

Using the flat end of a spudger, carefully work the spudger under the battery, lifting it off of the device.
The battery is very malleable, so do not try to pull it off all at once.

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
