Is this possible? I want to be able to connect my laptop to my desktop computer when I am away for my house(Which I am for most of the week). However, I don't want to constantly have my computer running, and want to find a way to turn it on or off when away from my house. (Sleep/out of sleep is OK if on/off is impossible) Any ideas?
Yes, this is completely possible. Look into Wake On Lan, and Magic Packets (i'm not joking, that's what they are called). Such services like Logmein, TeamViewer, and GoToMyPC, support sending a "wake up" packet to the NIC on your PC. Similar to a PIX boot option. Often times, these are not enabled by default, make sure your NIC has turned this option on. I have seen issues with DHCP, and attempting to do wake on lan. You may have to set a forwarding rule to do a broadcast, or possibly change to a static IP on the device you are attempting to wake up.
There are other ways to do this, but a pre-built software setup often are easier to get going. The only one of the three I've spent anytime with is Logmein.
Alright thanks, I got it to work. Sadly, that is only step 1. I want to be able to play games on my pc that my mac could never handle, but use remote desktop to actually PLAY from my laptop, even though my PC is what is running it. I know this is possible because I have seen people do it, I just have no idea where to start(Besides using a WOL to start my pc)
