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)
0.167 N·m (1.7 kgf·cm)
•
M2.5 (2.5mm)
0.294 N·m(3.0 kgf·cm)
•
M3.0 (3mm)
0.549 N·m (5.6 kgf·cm)
NOTE: To prevent damage to THIN HEAD screws, use type 0 bit philips screwdriver.
Use, however, the PH point size “1” screwdriver for screws fixing the memory
slot cover and 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.
