I think he wants to use 1 ps to simulate the battery, & one to simulate the ac power, in an attempt to devise a way of startup,shutdown wirthout going to the on switch on the mb...

I don't like it, I think you'd be much better off just opening the unit & tapping the power switch... also, in your scheme the laptop will still not survive crank....

I would rethink this approach...

You are correct, turbocad6. OK. That's what I wanted to know. I actually did go to the on switch on the motherboard using a hardwiring and soldering technique. The reason for this was to use the computer's internal circuitry to control the shutdown. Startup is already taken care of. My battery was going bad, so I decided I might try this. I will probably just go with the carnetix, though, after hearing your opinions. I was just trying to save a little money if possible as I had the targus psu's laying around. I don't want to burn my laptop up again, though. I tried a cheap psu on ebay when I unplugged the supply, my laptop turned off and wouldn't turn back on. I'm afraid to try it again after installing new board and processor in my laptop.
