Error Beep(s)
Computer beeps at startup.
1.
RAM expansion DIMMs for the eMac must be PC133 compliant and use SDRAM devices. If the user 
installs a DIMM that uses EDO or SGRAM devices, the computer will beep several times when the user 
attempts to restart the computer.
2.
Refer to “Power-On Self Test” mentioned earlier in this chapter.
Long tone at startup 
A long tone at startup can indicate that the power button is being held in, or is malfunctioning. This tone is 
normal when purposely holding the button in during startup. 
1.
Attach a known good power button to the unit and test. If the tone no longer sounds at startup, replace 
the power button.
