The BIOS allows to suspend the whole system. The BWRBTN- or LID- signals start the suspend procedure
(by connecting temporary to the ground).
The BIOS save the memory and all states of the peripheral chips to a file on the harddisk, finished by stoping
the power.
The whole system is stopped now and the power consumption is down.
By initiating the LID- or BWRBTN- signals again, the system starts to resume.
The BIOS starts the power, the CPU begins to work, the BIOS read the suspendfile from the harddisk.
All peripherals and the memory are restored and the system begins to work exactly at that point, where the
suspend mode had been started.
See also chapter 4.16 for measured values.
