There may be a hardware problem.
• If you added hardware, remove it and restart the
computer to see if the problem is corrected. If the
problem is corrected, you may not have installed your
hardware correctly. Reinstall your hardware.
For instructions on installing hardware in the system
unit, see the Aptiva online help.
If the problem is not corrected, see "Solving hardware
problems" on page 38.
• Make sure that the system memory modules are
properly installed. If the memory is not installed
correctly, the system will beep several times (in a 2
long beeps - 3 short beeps sequence). Reinstall the
memory modules. If you hear a beep sequence other
than the 2 long-3 short beeps, or if the memory
modules are installed correctly, see "HelpWare
support and services" on page 79 for information on
obtaining service.
If you have not added hardware, see "HelpWare
support and services" on page 79 for information on
obtaining service.
There is a problem with the system unit. Find the error
code or message in the section "Responding to error

The system has passed the Power-On Self Test
(POST).
If any of these problems continue after taking the actions
listed, run the diagnostics programs that came with your
computer. If you need service, see "HelpWare support and
services" on page 79.
