Cautions Before Disassembly
i.
Power off the device:
Before disassembly please power off the device
and take out the battery.
ii.
Press the power button
more than 5s after the battery is removed, to
release the electricity residual in capacitors.
iii.
ESD Protection:
Electronic sensitive components inside, (esp. in winter)
suggest to release the static electricity on the body (e.g. finger touch
metal objects).
iv.
Pay attention to the three different types of screws:
1. Black Phillips head (M1.4) (for display repairs)
2. Silver Phillips head (M1.4) (for other repairs, not involving PCB)
3. Torx head (for repairs involving accessing the PCB)
v.
Prepare your tools:
1. Phillips screwdriver PH00.
2. Torx screwdriver T5.
vi.
If you are a professional repairer, consider the torque force
needed for
screw/unscrew operation:
1. Torque Force for Philips screws: 0.8±0.15KGF
2. Torque Force for Torx screws: 0.4±0.05KGF
