Modem
Setting for [System standby]
• Roughly consider the communication time and then set [System standby]. There
may be cases where the computer enters the standby mode after the time set for
[System standby] elapses, even during communications, and cuts off the
communications
• If [Never] is set, the computer will not enter the standby mode during
communications; but once the computer resumes, the power will remain on, even
while the user is absent.
When the Ring Resume function is in use, some time elapses before a connection is
established (equal to the time for the computer to resume). To allow the computer to
resume, set the "Call" to a larger value than a typical telephone call. If it is not possible
for the sending side to set a long "Call", set the "Number of rings until answer" (with
the software application to maintain the condition to receive telephone calls) to a small
value.

former screen display will be restored when the keyboard or touch pad is touched
The computer cannot resume if a telephone is connected to the modem line (e.g., a
PC Card modem) other than the internal modem
