Introdução

Use this guide if your Samsung Galaxy Tab A8 battery isn't charging or functioning properly.

Before you continue, we suggest you review your device's battery settings and health. For additional help, use this troubleshooting guide: Samsung Galaxy Tab A8 Battery Doesn't Hold Charge

The Lithium-ion battery is able to store and supply power to the tablet without being plugged in. However, it can degrade over time and lose its capacity (mAh). Replacing the battery can extend your tablet's lifespan and improve performance.

Working with lithium-ion batteries can be hazardous. If connected or swollen, it can catch on fire if damaged. Before starting this repair, discharge the battery to 25% and disconnect the device from all peripherals.

Ferramentas

Passo 1

Fully power off the device.
Orient the screen so it is face-up.
Apply anti-clamp or other suction device to apply constant upward force on the screen.
Heat the screen to soften the adhesive with a heat gun or blow dryer. Be sure to heat all sides as evenly as possible.
Be careful not to overheat the device, as that could cause damage. It should be just too hot to touch.

Passo 2

Use plastic opening picks, or a Jimmy if necessary, to remove the adhesive and get under the screen.
Using the plastic opening picks, move around the screen slowly, one corner at a time. Every few inches, leave an additional opening pick behind where you are working to hold the screen open while continuing to remove the adhesive.

Passo 3

Continue to pry the screen off with the opening picks, using additional tools if more leverage is required.
If the device cools and the adhesive solidifies, reheat the device where necessary to soften the remaining adhesive.
Avoid using metallic tools, as doing so could cause damage to the screen or other internal components.

Passo 4

Using a Phillips #000 screwdriver, remove the 1.8mm screw holding the clamp that holds the screen ribbon in place.
Remove the battery connector ribbon to help prevent short circuiting of the device and/or shock hazards.

Great explanation

One tip from my experience with removing some Tab A8 displays:

Once the screen is loose,

Don't immediately start prying between the display and the PCB assembly with a screwdriver.

Instead, look at where the display cable is connected to the screen.

Because that's where it's attached to a so-called flip connector. Just loosen the adhesive tape.

Remove the flip-up ribbon cable from the screen.

This way, you can prevent yourself from breaking or pulling anything.

You have a more limited view of your work, because your hand with the screwdriver is working between the two panels.

My first repair job cost me a brief moment of inattention.

More extra work because I had to replace the ribbon cable connector on the PCB.

Again, not a comment on everyone's approach to repairing electronics.

But I want to encourage beginning DIY enthusiasts to follow this video and incorporate this tip into their disassembly/repair process.

Kind regards
