Auto Boot PC

[YueHong]

I have found some applications that can auto boot the PC with the condition that the PC is being hibernate (not shutdown). Just curious, what is the differences between shutdown and hibernate? Why the PC can't auto boot from shutdown? My PC is kinda old, so I can't set the auto boot in the BIOS. Is there anyway that I can have the PC auto boot from shutdown? Thanks.

No, not unlessy your PC has the "Wake-On-Lan" option in the bios.

Just use hibernate.
The power usage level is so low there that it should not really matter.

Hibernate saves the RAM contents to memory so you can start up and load that back up which results in a faster bootup. Shutdown completely shuts down the computer.

Thanks for your reply. Wake-on-Lan? How does it works?

"Wake-On-LAN" puts the PC into a very low power state.
In essence just the NIC is awake and then it will sit and listen for the right network packet.

If it gets it, then it will power on.

Actually you can wake a PC at a given time if your BIOS supports wake on RTC. Some BIOS settings have the ability to specify a time and date to boot the computer. The other thing is, most BIOSes support this feature whether they have the option page or not, so if you could find some sort of program (WinACPI used to be a general ACPI test tool that had this) that managed the ACPI table, it might have the ability to set the wake on RTC feature regardless of if your BIOS supports it or not.

Our Biostar T-7025 motherboard has the RTC mode, allowing to set a date and time for boot. Whether one time, daily, weekly, certain days of the week ect. It's pretty nice. Of course it also support WOL. It makes a very nice motherboard for our fileserver .
