SYMPTOMS

When you suspend and then resume a laptop computer with the hardware Power/Resume button, the computer may power off instead.

CAUSE

The Windows 95 power management driver may not properly handle a suspend request and cause the computer to power off when the following conditions exist:
  • The computer is a laptop computer with a BIOS option to select the power-up (or resume) mode. Such an option determines whether the power button actually powers the computer on and off (for a full reboot), or simply suspends and resumes the computer.
  • The power-up (or resume) mode option is set to resume mode.
  • The computer is placed in its docking station and powered on.
  • The power button is pressed to place the computer in a suspended state.
  • The power button is pressed again to resume the computer.
  • Instead of resuming, the computer peforms a full power-off after about 30 seconds.

RESOLUTION

To work around this issue, set the power-up (or resume) mode option to boot mode instead of resume mode. This causes the computer to completely power off when it is shut down and perform a full boot when restarted, instead of suspending when shut down and resuming when restarted.

STATUS

This problem no longer occurs in Windows 98. To resolve this problem, install the current version of Windows. For information about the current version of Windows, visit

MORE INFORMATION
