2.1.2 Opening the top cover (front half)
To open the top cover:
1. Push the two sliding locks on the
top cover to release the front half
of the top cover.
2. With both hands, flip up the front
corners of the top cover then lift
the front half.
The front corners of the cover
have dents that match those on
the chassis. These dents provide
a holding mechanism and keeps
the cover in place even when the
sliding locks are released.
If you wish to access the hot-swappable system fans, backplanes,
optical drive, and floppy drive, you only need to open the front half of
the top cover.
