Screw Tightening Torque
Use the following torque when tightening screws.
Caution: Overtightening may damage screws or parts. Undertightening may allow screws
to loosen (and possibly fall out) causing a short circuit or other damage.
Note: To tighten screws quickly and accurately, an electric screwdriver is recommended.
M2 (2mm)
M2.5 (2.5mm) 0.294 N m(3.0 kgf cm)
Note: To prevent damage to THIN HEAD screws, use type 0 pit Philips screwdriver.
Use, however, the PH point size "1" screwdriver for screws fixing the expansion
memory slot cover and the keyboard. Press along the axis of the screwdriver while
turning the screw. This is because the contact area between the screw and driver is
less than for a pan head screw (standard pan-shaped screw head).
Grip Color
Some screws have a colored grip area to help you determine the length of the screw.
Even numbered length screws: Brown
Odd numbered length screws: White
Special length screw: Blue
"Special length screw" means screws whose length is indicated
in an integral number to the first decimal places such as 2.5 mm,
2.6 mm and so on.
