All the computers I owned in the last 10 years all had the ability to automaticly turn on at a certain time, configurable through BIOS/CMOS settings. Most boxes I had b4 that had an options to automaticaly startup after a power outage. Am I the only one with boxes like that?
Use this option with a device that automaticaly turn the power on and your in business to. If both options are unavailable for you then you do have a problem, although putting a jumper over the powerswitch connector on your mainboard might be worth a shot.
After that of course the autologon, automatic email retrieval by starting your email client, and a bacht file that waits for half an hour, and then turns off your computer again.
Another options is to automaticaly forward (and delete) your email to another addy. This of course would have to be an feature tht is provided by your ISP.
Last option is to ask friends/family to retrieve the messages for you, and save them in a PST file for ya.
PM me if you can't get this solved, there are many ways to solve your problem, I might be able to provide one for ya.
