BATMThree Components

It happens. Electronics fail; parts wear out. Like a light bulb, sometimes they don't last long at all - other times they last forever!  

Open

CPU/Coreboard

• Check for proper seating of the CPU coreboard.

• The metal edges of the contacts should be even and barely visible.

• The coreboard is connected and held in-place by the two clips.

Open

WiFi Antenna

The WiFi antenna is attached to the door, facing outwards, covered by the GB label. The other end is a U.FL micro-coax cable fitting and it simply presses onto the socket located on the coreboard.

• REMOVAL: Gently lift the WiFi cable connection up & off with a screwdriver.

• ATTACHMENT: orient the fitting over the socket and press gently down. The cable should be oriented as shown for proper seating.

AKAREL23 Mainboard

• REMOVAL: Take a picture for reassembly. Disconnect the cables (in orange), taking care to mark the USB cables - they must be reinserted in the same locations. Unscrew the 4 mounting screws (in red).

• ASSEMBLY: attach the mainboard to the bracket. All 4 screws must be used, do not overtighten. Attach the cables, making sure to insert the USB cables in their proper positions.

Inverter

The LCD panel’s backlight is integrated into the display panel. An inverter converts the mainboard power to a usable backlight power supply. A failure in the inverter or the attaching cables will result in a blank display - while the BATM itself chugs along like normal (the BATM will still appear online).

Inverter failures are very rare - but still possible. Check the cables & jumpers closely - first.

The mainboard:

• The other end of that circled cable (from the mainboard) connects to the inverter at “B”.

The Inverter:

• “A” connects to the display panel:

Troubleshooting:

If the BATM won’t turn on, the following items should be checked:

Items outlined in green are necessary for the BATM to turn on.

• The coreboard is required, as well as the power supply barrel connection and 2 display cables.

Items outline in red are attached to other peripherals that may be causing an issue.

• A defective item attached to the mainboard may prevent it from booting properly.

• Disconnect peripherals when attempting to determine if the mainboard is at fault.

• If the issue remains after those cables have been disconnected, then the coreboard and/or mainboard may be defective. Further troubleshooting is required.
