Notes:
  1. You may need to charge the Venue 8 Pro (3845) tablet before you use it, as it is possible for the tablet to discharge during shipping. When the tablet is charging and the LED flashes amber, the battery is at a critical level and does not have enough charge to power on. If the power button is pressed during this state, the LED will turn on for 3 seconds and then turn off. Continue charging the tablet.
  2. The micro-USB connector on the Venue 8 Pro (3845) can support data transfer or AC power but not both at the same time. When it is connected to a USB port on a computer, it automatically switches to data transfer mode and will not charge the battery. To charge the device, always use the AC power adapter with the USB-to-micro-USB cable supplied with the device. The micro-USB port is located on the upper right edge of the tablet (Figure 1 and 2).
  3. Normally, the battery will require about 4 hours to fully charge. The charge status can be checked from within the operating system.

Tablet charging troubleshooting steps:

The best way to troubleshoot this issue is to setup a test station with a known good tablet, AC power adapter and Micro-USB cable, if available.

  1. Check the AC power adapter that came with the tablet by using a known good Micro-USB cable with known good tablet, if available.
  2. Check the wattage displayed in the tablet BIOS, if the correct wattage is shown (10 watts) then no further action are needed, continue to use the same adapter and cable to charge your tablet.
    To get into the BIOS, perform the following steps.
    1. With the tablet off, press the Power button and the Volume down button until you reach the BIOS screen.
  3. When the BIOS shows less than 10 watts, unplug the AC adapter from the wall for 10-15 seconds and then reconnect.
  4. Check the BIOS wattage again. When it still shows less than 10 watts, try another AC adapter if available, when using another AC adapter and it still shows less than 10 watts, then try another USB to micro USB cable if available. If another cable is not available, try gently moving the micro USB connector where it attaches to the tablet and note any changes in the wattage. Inspect the cable (especially the Micro USB end) and the Micro USB connector on the tablet. Replace the affected component. If the connector on the tablet is damaged, the system will require service to replace the USB daughterboard to resolve.
