Speaker Failure ¶
You have trouble listening to sounds coming from the speaker on your tablet.
Volume is Muted or Turned Too Low ¶
Check your volume settings and make sure they are turned up and unmuted.
Speaker Connection is Broken ¶
The electrical connection to the speaker may have been damaged or broken. This could be a result of overuse or opening the back panel of the tablet too forcefully.
Internal Software Error ¶
An error, flaw, failure or fault in the system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways.
First, try powering off the device and restarting it to see if this fixes the problem. Try to use a different audio cable to ensure that it is not just a faulty headphone problem. A factory reset may be needed to fix this issue, which can be done using the following instructions:
1. Power down your device by pressing and holding the power button located on the top left of the tablet.
2. Turn the device back on by holding either of the (+) or (-) volume buttons and the power button at the same time. Continue holding the volume and power buttons until a picture of the Android logo appears on the screen. This should take approximately 15 seconds.
3. After the Android robot image has loaded, a menu will appear. You can navigate the options using the power button to select, and the (+) or (-) volume buttons to move up or down.
4. Move the cursor to the "Factory Data Reset" option and select it. Then select "Yes" when prompted, and the tablet will begin the reset. Allow the device to complete the reset process.
5. Once the device has finished the reset, select on the screen "Reboot Tablet Normally". Your device will now reboot to its factory defaults.
Hardware Malfunction ¶
The speaker may be broken or damaged in some way and needs to be replaced. Here is a guide to replacing and repairing the internal speaker on a similar Apex Tablet: Repairing Apex Tablet 7 Internal Speaker Replacement
Display fails to work ¶
There is nothing displayed on the tablet's screen. You only see a black screen.
Device Is On Stand-By Mode ¶
The screen on your tablet may be momentarily shut down due to inactivity. If your tablet is in stand-by mode, then the tablet is still powered on, but the LCD screen is deactivated. To reactivate the screen quickly press and release the power button located on the side of the device.
Device is Not Powered On ¶
Make sure that your tablet is powered on. To power on the tablet, press and hold the power button located on the side for a few seconds. If the screen doesn't power on, then the tablet might need to be recharged.
Device is Not Charged ¶
The battery life could be too low and not sufficient enough to power the screen, or the battery could have completely lost charge. If this is the case, simply recharge your tablet.
There are two ways to recharge your tablet. One way is to connect the AC adapter, that was included with your tablet, to your tablet's powerjack, plugging the other end of the AC adapter into an AC power outlet/socket. Another option is to connect the USB cord, that was also included with your tablet, to the tablet, then connect the other end into the USB port in your computer/laptop. While both methods will recharge the internal battery, recharging via AC power will take less time than recharging via USB.
Faulty Battery ¶
If you have tried to recharge your tablet but it still has no power, the battery is probably dead and must be replaced. Here is a guide to replacing the battery on a similar Apex Tablet: Apex Tablet 7 Battery Replacement
