Actually WOL from standby is very fast on a PC running Win XP. Typically if I leave my monitors on, the PC will be "alive" and usable before the LCD monitor screen comes on fully. Standby state - S3 powers down everything except RAM and freezes the CPU. What you seem to be refering to is hibernation - S4, which write the contents of RAM out to the HD and powers down almost completely. Resume time then becomes a function of how fast the HD can reload the data to RAM, how fragmented the HD is etc... If you have an old PC that does not support ACPI, your standby/hibernate experience may be completely different. See here http://www.microsoft.com/windows2000/techenthusiast/features/standby1127.asp * APM offers power management only for those devices under BIOS control. Devices such as IEEE 1394 devices, which are not on the motherboard, cannot be power-managed. ACPI is not limited in this way. * Enabling APM on some systems causes instability. In Windows 2000, Setup will automatically disable APM in systems with known problems. * ACPI provides more device-specific power management. Also, ACPI can place your computer into five different power states. As your computer drops into deeper levels, it takes longer to resume from Standby. APM does not have this flexibilityStandby in APM is either on or off. * ACPI power states include: o S0 Active, with all power on. o S1 Standby, with display and drives powered off, but power maintained for CPU, memory and fans. o S2 Standby, with CPU and cache power off. o S3 Standby, with only minimal power maintained to RAM for a fast startup. (This is useful for desktops because it keeps your PC ready to use, but eliminates noise from fans and disk drives.) o S4 Hibernate with all power off and the image of your desktop saved to disk. o S5 Complete power off with all files closed and no image saved to disk. -- oreillymj ------------------------------------------------------------------------ oreillymj's Profile: http://forums.slimdevices.com/member.php?userid=699 View this thread: http://forums.slimdevices.com/showthread.php?t=18144 _______________________________________________ Discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
