Wake-on LAN with Hibernate
I have a home network setup, my Laptop is connected wirelessly. I am running Windows XP Home on both.
When i am not using my Desktop, i have it go into auto-hiberbate when not in use for 15 minutes.
I have heard of a term called wake-on LAN, where one computer is able to "wake up" another. I see only an option for stand-by mode, however i do not use. Does this work with hibernate? I have tried changing some settings on the network card, via the Device Manger. So far i have not been able to do anything.
I want to be able to access files on my Desktop when using my Laptop, without having to power up the Desktop.
Any help would be great.

Hi,
are you sure ? I thought that ACPI compliant hardware, BIOS and OS must be able to wake up via LAN magic pakets from alle ACPI states S3, S4 and S5 ? Am I wrong ?
I am specifically interessted in the Inspirion 530. What states does WOL work with, i.e. from what states can the computer be woken up to then serve as a File Server and UpNP Server ? I was thinking of buying a NAS, but as I do not need 24/7 instand access I thought that remotly waking up a desktop would be a cheaper option.

Your response for WoL is totally incorrect, and it should not be accepted as "The Solution". Unfortunately, there seems to be no mechanism to fix this. Wake on LAN uses "magic packet". It is specifically used for powering on when the PC is off. It is when the PC goes into hibernate or sleep that issues arise depending upon the drivers. Wake on lan does nothing to save files or anything of the sort. Please do not just reply to messages if you do not know what you are talking about.
the correct answer is: WoL will wake a PC from an off state provided that the IP, subnet, mask and broadcast have NOT changed from the time when the PC was turned off. Sleep mode and hibernate can be made to work with the correct drivers. No Dell I have ever had will support WoL from sleep or hibernate.

Hi DanTheMan,
thanks for your precise answer. What does one need to look for if WOL from any of the "sleep or off states" S3,S4,S5 is required? I actually never have found any specs from any vendor which indicates if this possible or not. Is it a misconception of mine that adherance to ACPI spec implicitly also means fill WOL implementation ?
Dell is regretfully very vague about any specification. Things which are important to me such as WOL, DVI interface, gigabit ethernet etc. are not described at all for the Inspirion 530.
Is my intended use for WOL (see prior post) maybe stupid in itself ? Some things seem good in theory but do not really turn out as a good idea in real life.
Steve.
