high power consumption compare to GOOD main board.
(1) Requirement
- Power Supply
- Micro-current Meter
- Current series JIG
- CABLE
- Battery JIG

1.Equipment need:
A. Power Supply (set at 4 V /1A).
B. Micro-Current Meter (support 0.5mA ~ 1A).

Tap Start->System->Backlight.
IV. Adjust the backlight level to 0% and
checks the current from current meter.
[Note1]
V. Press power button to initial device enter
sleep mode and checks the current from
current meter. [Note2]
[Note1]: 49mA (Spec TBDmA).
[Note2]: 1.88mA (Spec TBDmA).

Conclusion
I. If current consumption test PASS when UUT in Flight and Sleep mode, it means that the
M/B works normal.
II. If current consumption test FAIL when UUT in Flight or Sleep mode, it means that the M/B
works abnormal, please replace M/B and re-test again.
