Your computer may spontaneously suspend immediately after you cause it to resume by pressing the power button on the keyboard. This problem is likely to occur only if you suspended your computer from the Start menu, and is not likely to occur if you suspended the computer by using the keyboard power button.
CAUSE
When you press a sleep button on keyboard, a VK_SLEEP keycode message is sent to Power Manager (Vpowerd.vxd) by the Windows kernel. Vpowerd typically ignores messages while it is busy with a resume. However, there is a small time window in which Vpowerd can react to messages; if a VK_SLEEP message arrives during this time, the message is treated as a legal sleep request, and the computer is suspended.
