Introduction
This technical manual applies for the mainboard D1085. This system board is available in different
configuration levels. Depending on the hardware configuration of your device, it may be that you
cannot find several options in your version of the system board, even though they are described.

2 Mechanics
Computer mainboards and components contain very delicate IC chips. To protect

them against damage caused from electric static, you have to follow some
precautions:
•
Unplug your computer when you work inside.
•
Hold components by the edge, don’t touch their leads.
•
Use a grounded wrist strap.
Place the mainboard and the components on a grounded antistatic pad whenever
you work outside the computer.
Once you have installed the system board, you should remove the battery
protection (i.e. the thin plastic plate between battery and contact spring).
