Takeaways

• 😀 The Google Nexus 7 2013 model can experience battery issues, rendering it unable to start.
• 😀 Google's recommended method to reboot involves holding down buttons while charging, but this may not work if the battery is severely drained.
• 😀 The solution involves 'jump-starting' the battery by directly sending power into it from an external source.
• 😀 Opening the back of the Nexus 7 and accessing the battery is necessary for the repair process.
• 😀 A USB cable (that you don't need) is cut to expose the black and red wires for power delivery to the battery.
• 😀 The black and red wires from the USB cable are connected to the corresponding terminals on the tablet’s battery to provide power.
• 😀 The process involves charging each cell of the battery individually by connecting the black and red wires to their respective terminals.
• 😀 Charging for around 30 minutes per cell (outside and inside) is sufficient to jump-start the battery without causing damage.
• 😀 A voltmeter is used to ensure that the 5V USB power source delivers the necessary 3.7V to the battery without damaging it.
• 😀 Alligator clips are recommended for safely connecting wires to the battery terminals, although alternatives like a paper clip can also work in emergencies.
• 😀 After successfully jump-starting the battery, the tablet should be plugged into a charger and the power and volume buttons held for 20 seconds to initiate a reboot and shutdown sequence.
• 😀 Once the tablet has successfully shut down, it should be able to reboot normally, indicating that the repair process worked.
