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.

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.

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.

Edit

Step 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.
