Advanced Power Management (APM)

The Advanced Power Management (APM) is a standard, defined by Intel and Microsoft, for a power-saving mode that is applicable under a wide range of operating systems. The version APM 1.1 supports the following modes: Fully-on, Standby, Suspend, and Off.

The Suspend mode, which also used to be known as Sleep, is now managed at the operating system level only. There is no longer the inter-activity between BIOS Setup and operating systems, and no longer a “sleep at” item in the Setup menus. This is to avoid the BIOS from shutting down the system at the wrong moment.

The HP Vectra 500 Series desktop backplane supports two 16-bit ISA (Industry Standard Architecture) cards, one 32-bit PCI (Peripheral Component Interconnect) card and has one combination slot for an ISA or PCI card.
