Reload Global Timer Events 

The HDD, FDD, COM, LPT Ports, and PCI PIRQ are I/O events which 
can prevent the system from entering a power saving mode or can 
awaken the system from such a mode. When an I/O device wants to gain 
the attention of the operating system, it signals this by causing an IRQ to 
occur. When the operating system is ready to respond to the request, it 
interrupts itself and performs the service.
