Search around the forums.
There are a number of ways to pull this off. It's all about which method will work best for you.
I'm going to simply use a car power adapter with a relay that will provide power to the laptop when the acc is high. I'll then tell Windows to shut down the computer after an amount of time. The only problem I have is turning it on. If I standby or hibernate, all I need to do is, say, press a key on a keyboard and it will turn on. Any way to automate that? What happens when a key is pressed?
I'm not interested in a special power supply, and really the only thing that is left is figuring out how to turn ACC into a keyboard press.
All I've found by searching is about controlling the power button. I am not going to go into that. I know a computer capable of S3 sleep can be turned on by certain USB conditions. I am asking if anyone knows of a way to wire a usb device to ACC that will cause this USB event.
Edit: This could work, but I was thinking of USB instead of RJ45 because my laptop probably won't support WOL.
Use an ipac. It's a keyboard simulator that you can wire a switch -or a relay to. Just remember to use a momentary relay or you'll have continuous keypresses.
laptop will wake up on USB ?
Is this the IPAC? :
These are the steps I take: 1) turn laptop off. 2) connect lcd tv to laptop via vga cable. 3) Set lcd tv to vga input. 4) Turn on laptop.
The lcd tv shows the bios screen and loading windows screen perfectly fine. When windows loads, the lcd tv goes blank and says no signal.
I'm using windows 7 ultimate. Please help
