Some Toshiba Laptop Computers Do Not Suspend Automatically (132765)


The information in this article applies to:

  • Microsoft Windows 95
  • Microsoft Windows 98
This article was previously published under Q132765

SYMPTOMS

If you are running Windows on a Toshiba laptop computer, the computer may not automatically go into low-power suspended mode.

CAUSE

This behavior occurs because some Toshiba laptop computers monitor the interrupt request (IRQ) lines (except IRQ 0) to determine if the system is busy. Any hardware interrupt (other than 0) resets the auto-suspend timer. Windows generates interrupts that prevent these computers from going into low-power suspended mode.

RESOLUTION

To work around this behavior, suspend the computer by clicking Start and then clicking Suspend, or use the hardware switch.

MORE INFORMATION
