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!

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.

Open

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”.

The Inverter:

• “A” connects to the display panel:
