Optional Devices 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 a #0 point Phillips screwdriver to remove and fasten the screws - the use of an incorrect screwdriver can damage the screw heads. Installing a memory module The computer contains slots for two memory modules, one positioned immediately over the other - the procedures are the same for installing either module. 1. Set the computer to Boot Mode and turn its power off - make sure the Power indicator is off (refer to the Turning off the power section in Chapter 3, Getting Started if required). 2. Remove the AC adaptor and all cables and peripherals connected to the computer. 3.
