Point to note about memory module error
If you install a memory module that is not compatible with the computer, the
Power indicator will flashes (on for 0.5 seconds, off for 0.5 seconds) in the
following ways;
■
If there is an error in only Slot A or no memory module is inserted in Slot
A: repeatedly flashes orange twice, then green.
■
If there is an error in Slot B: repeatedly flashes orange, then green
twice.
■
If there are errors in both Slot A and Slot B: repeatedly flashes orange
twice, then green twice.
In all instances you should shut down the computer and remove the
incompatible module(s).
Use an adequate screwdriver to remove and fasten the screws - the use of
an incorrect screwdriver can damage the screw heads.
