It happens. Electronics fail; parts wear out. Like a light bulb, sometimes they don't last long at all - other times they last forever!
ALWAYS unplug your BATM before attempting disassembly or installation. |

The internal electronics are protected from accidental damage by a physical cover. This also provides a certain measure of EMF shielding.
To access the Coreboard, the Mainboard, or to inspect critical connections, the cover should be temporarily removed. Removal is simple.
The cover should now drop down into your hands.
Be careful to avoid snagging any cables.
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.
Unplug all connectors identified above.
Unscrew the 4 mounting screws (and 2 standoffs):
Installation is the reverse order of removal.
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 other end of that circled cable (from the mainboard) connects to the inverter at “B”.
“A” connects to the display panel:
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.
