Some Toshiba Laptop Computers Do Not Suspend Automatically

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

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.

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

The following Toshiba laptop computers are known to exhibit this behavior:

• T1910
• T2100
• T2400
• T4850
