installing an expansion memory module. To discharge your body's
static electricity, simply touch any metal close to you with bare hands.
If you install a memory module that is not compatible with the computer,
beep will sound when you turn on the power. If the memory module is
installed in slot A, there will be a long beep (1 second) followed by two short
beeps (0.5 second each). If the memory module is in slot B, there will be a
long beep followed by four short beeps. If the both memory modules in slot
A and slot B are incompatible, there will be a long beep followed by two
short beeps and after a pause (1 second) a long beep followed by four
short beeps. In this case, shut down the power and remove the
incompatible module(s).
Be sure to install memory module to slot A. The computer does not boot
