Thread: Turning on laptop...this has been discussed

that mechanism HAS to connect to a switch that may be part of the mechanism, the computer has no way of knowing anything about mechanism's, all it can see is continuity between two points,those two points will be a ground reference & another that sees a ground pulse as an on signal request... you have to find these two points... any pictures??

The laptop is about 4 years old, it is a toshiba satellite A25-S207. What is the simplest method for me to turn of my laptop in the car? I am sick of getting out and pressing the button in my trunk every day. Please dont just tell me to . I just need some help, (BTW im only 16).

Like TC said. That mechanism is connected to wires. At some point, the computer, an electrical device, needs to know that the button was pushed. THat is the point which you have to solder to. Just like, your car, when you put the key in and turn the it, that is mechanical, but the car knows this is donw because WIRES CONNECT power.

Pictures would be helpful, but they are probably no different then any other laptop.

Of course, if you are unwilling to use WOL, WOR, etc.., and your laoptop is "mechanical" as you state, then you can't use the laptop. Get something else.

I don't want to mess with this..
I don't have that..
I can't do something else..
Don't tell me to search..
I just need help..

I recommend a long pole....but not to push the on/off button with!!! ;-)

if you really can't mess with the switch (wimp), a cable like a gastank release could be rigged, (bicycle cables) or a small electrical solinoid could be rigged even, but cleanest is to just go to the board...

take you laptop apart and just solder the damn wires on the frikin switch and wire to your car how you see fit. No need for mechanical this or that.

I found the pin that presses the power button on the bottom docking station port. I doubt it is the same but it was just one pin and then a ground to the case to turn it on and off... I have a picture if it would help. Though mine is an IBM laptop.

got a question do the length of the cables matter... like will it lose signal after so far?

Which cables? And yes, it does and it will.

Yup, think of Ohm's law, V=IR

The longer the cable, the more resistance. (R)
