Screws

  This page is monitored by the OLPC team.

These are the screws used in the XO laptop, and their locations. As per http://en.wikipedia.org/wiki/ISO_metric_screw_thread the number immediately after the M is the rough diameter, followed by the pitch after the first x. Two of our screws have a precise length in english units, but not metric units.

From left to right:

• (A) M2x.4 x 4mm - the common blackened ones. There are a lot of these - use anywhere a specific type of screw is not specified.
• (B) M2x.4 x 2mm - the short shiny ones. There are 4 of them. 2 of these hold the keyboard controller circuit board in place, the other two help screw the keyboard to the keyboard bezel. Holes for these screws are marked with this symbol: .
• (C) M2x.4 x 6mm - the long shiny ones. There are 6 of them. Four are used to attach the back cover (over the motherboard). Two are used to hold the hinge cover together, one on each side.
• (D) M2.5x.45 x 0.5in - The antenna ear screws. Four of these hold the antenna ear clamps in place.

Not shown:

• fat M2x.4 x 0.3in - the screen screws. These are cushioned by 4 black rubber ring bumpers and hold the screen in place.
• M3x.45 x 5mm - There are 4 of them. These attach the hinge to the bottom half of the laptop.
