Why nonstandard screws?
Out of curiosity, why were nonstandard (unusual pitches for their diameter, replacements not easily findable in hardware stores) screws used? Someone asked me this question once and I didn't know the answer. Mchua
- Those screws aren't that non-standard. Dismantle any laptop, and you will find identical screws. True, they aren't the old English standard (i.e. 2-56, 4-40)... The correct answer is that Quanta was allowed to decide specifications for laptop components that weren't specified by OLPC. They generally choose those specifications based on what was readily available at low cost from their suppliers.--Wad 21:39, 6 April 2009 (UTC)
JIS ?
Screws A, C, D, E & F appear to be JIS (Japan Industry Standard). The heads on these look like Philips, but are not. JIS screw drivers can be found in specialty tool stores. Mine are made by Moody Glenn WB4UIV
- Under close inspection, those screws appear to have the rounded corner of a phillips head, versus the square corner of a JIS screw. It would not be surprising, however, as the laptops are assembled by workers with torque screwdrivers (there is no need to "cam out"). --Wad 21:39, 6 April 2009 (UTC)
Length of D screws
In my XO-1.5 the D screws are 3 mm long whereas the page shows "(D) M2x.4 x 2mm". I tend to doubt that any of the XO machines has an M2 x 2 mm long screw. Can anyone check another model? Please. Then the page can be corrected. Thanks, ... Peasthope 21:35, 18 July 2018 (UTC)
