In this article, we will consider how you can independently disassemble and repair a Samsung Galaxy Note 10.1 tablet.
We got a tablet in our hands that did not turn on and did not charge.
Before starting work, remove the SIM card, flash drive, and the stylus so that it does not interfere.
We will analyze it with the plastic tool shown in the photo below, but if there isn’t one, then you can use a pick or a plastic card.
We insert our plastic tool into the gap between the glass and the plastic case and bend it, releasing the plastic inner clamps.
We carry out this procedure from all sides of the screen.
When removing the back cover, be careful that the buttons do not fall out or get lost.
In addition to the buttons on the lid, there is nothing removable anymore, and we put it aside and go on to research the device itself.
Most of the interior space is occupied by the battery.
Given the nature of the malfunction of our tablet, the likely cause of the breakdown is related to the power system.
In most cases, the cord connector is the culprit, as many people sticking it continue to use the tablet and the connector loosens.
To get to the connector, you need to unscrew the two screws.
When unscrewing the screws, do not lose them, as they are self-assembled, and it will be problematic to find them for replacement.

Having unscrewed the screws, disconnect the cable (on the left on the photo above) and carefully picking up the edges.
On the other hand, the cable is connected to the connector on the board.
We hook the lock and raise it, freeing the loop, which after that is easily removed.
Having freed the edge of the loop, which is opposite from the damaged connector, grabbing at it we extend the connector.
This is how the power connector looks on the reverse side.
We are trying to measure the battery voltage.
If the battery is very flat, the device will not turn on even if the power is plugged in.
The voltmeter showed 1.14-1.15 volts. This is very small.
We try to disconnect the battery and charge directly through the charger.
After charging, the battery is measured with a voltmeter and it shows 3.75V. The battery is charged.
Turning on the tablet and connecting it to the laptop, it was identified as a flash drive, but the screen still remained dark.
Probably the root cause in the idle screen, and a discharged battery is already a consequence.
We try to drag the cable going to the screen by analogy with the battery cable.
In our case, after reconnecting the loop, the backlight turned on, but the screen remained dark as before.
After repeating the procedure, an image appeared on the screen.
Thus, we found the reason for the inoperability of the tablet, it is a flown screen plume.
This probably happened after the fall, and then the battery simply discharged, since it was not clear that it needs to be charged.
Reassemble in the reverse order.
