BATMFour 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!
ALWAYS unplug your BATM before attempting disassembly or installation.

Cover Removal
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.
1. Remove the 2 retaining screws.
2. Slide the cover back about 1 cm (1/4”).
The cover should now drop down into your hands.
Be careful to avoid snagging any cables.
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.
Gently lift the WiFi cable connection up & off with a screwdriver:
Mainboard
Removal:
Unplug all connectors identified above.
Unscrew the 4 mounting screws (and 2 standoffs):
Installation is the reverse order of removal.
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”.

Troubleshooting:
No Power
Power is fed from the wall outlet to a Schurter power line filter mounted on the rear of the BATM. If internal LEDs are not lit, then perform these checks:
the wall outlet is live,
the switch on the Schurter power line filter is ON,
both internal power supplies are plugged into the internal power distrubution strip,
the LEDs on both internal power supplies are lit (could indicate a bad power supply).
Blank Screen
If the BATM power is ON but the screen is blank - check that the devices inside your BATM are connected to your mainboard. The inverter connections should be checked, as well as the following mainboard connections:
Items outlined in green are necessary for the BATM display 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.
Rotated Display
The display is automatically set to 1080x1920 (portrait). This orientation is set during factory configuration and testing. If your BATMFour display is improperly oriented (landscape) then you must contact Support for instructions. Create a Support Ticket
