Problem	Solution
Device does not turn on.	Ensure the device is sufficiently charged. Connect it to a power source using the USB cable and AC adapter.
Device is unresponsive or frozen.	Press and hold the Power button for 3 seconds to perform a restart. If the issue persists, allow the battery to fully discharge and then recharge.
Cannot transfer files via USB.	Ensure the USB cable is securely connected to both the device and the computer. Try a different USB port or cable. Verify the device is recognized as a storage device on your computer.
E-books are not displaying correctly.	Ensure the e-book files are in a supported format (e.g., TXT). Some complex formatting in TXT files might not render perfectly.
Screen display is faint or unclear.	Adjust the backlight settings. Ensure the screen is clean and free from smudges. E-Ink screens have a slower refresh rate than LCDs, which is normal.
