Device fails to power on

The tablet will not power up, will not charge, or will not hold a charge.

Damaged or faulty charging cable

The first thing to check is the charging cable. Inspect it for damage, exposed wires, and broken or damaged ends. If the cable appears in proper working order, continue to other sections in this guide.

Disconnected or faulty cable

The main power cable connecting the battery to the circuit board may be faulty or disconnected. Check the connection. Check the cable for any tears or broken wires. If faulty or damaged cable is identified, replace it and try powering up the device.

Bad battery

The battery may have reached the end of its life. If the power cable has been ruled out as the cause of the device not powering up, disconnect and replace the battery.

Unresponsive buttons (power/lock, volume)

The external buttons on the tablet yield no response when pressed.

Power/lock and volume buttons

The power/lock button and the volume buttons are connected. Once the two main panels of the device are separated, this button cluster is easily accessed, removed, and inspected for damage. If the buttons do not appear damaged, check the dip switch that the buttons make contact with in order to signal the desired action. These switches can get dirty or even damaged from mishandling of the device.

Frozen or unresponsive touchscreen

The touchscreen does not respond to touch commands.

Broken or disconnected ribbon cable

Check the ribbon cables for damage. Make sure all connections are secure withe the lock tabs in the down and locked position. If cables are damaged, replace and try operating the tablet again. If the problem persists and cables are in working condition and connections are secure, it may be a software issue.
