Shutdown Controller and Laptops

**blackflux** · 03-29-2005, 01:35 PM

Can someone explain how I would wire up one of those shutdown controllers to send my laptop into hibernation (i.e. wired to the power button on my laptop and or a docking station)?

I was thinking about using the uSDC20D micro Shutdown Controller. I understand that a wire has to go to ground, another wire has to go to the ignition, and another wire has to go to the car battery (positive).

The part that is confusing is how to wire it to the power button on the laptop when the controller is made for ATX computer/power-supply.

take apart your laptop apart and wire it in parrarel to the button that turns your laptop on

the power button for a standard ATX mobo shoudl be the same for laptops. At least it is the same on mine.
Check my sig below and go to post #52. I have some pics of the uSDC20D controller hooked up to my dell laptop with docking station.

I have a Sony laptop and a Dell and neither of them have jumper-style pins like an atx motherboard, just pads that the button is soldered to. I ended up using the Dell in the car and had to solder wires to the pads and extend them outside of the laptop case to hook up to my shutdown controller.

So, to the original poster, you have to take it apart and look where the power button is hooked up to. If it's just pins then you lucked out and you can hook it up to that, otherwise you might have to do some soldering.

There are also shutdown controllers available that can shutdown via the serial port and some software (eg. DSSC), but these I don't think there is a startup option when you use it like that so you will have to setup the laptop BIOS to resume on power loss (if it has that option in BIOS).

Thanks people. Since I have a docking station I can solder the controller to the power button on that. But that's not really an issue, I am more concerned about wiring it correctly and that it (uSDC20D) will actually work.

So with that said what's the best controller to get to use with a laptop?

I want to know as well. I have a HP Pavilion N5190 Laptop with docking station for my project. I am almost done, and this is one of the final touches to complete my project.

I guess I will need to take one of my docking stations apart to see what's what.

Our shutdown controller will do serial port shutdown, so you don't need to open the laptop. When using serial port shutdown, you do have to turn on the PC by yourself though.

Check it out, it is so much more than just a simple shutdown controller.

Whichever controller I use has to be able to startup the laptop. I just wish I knew more about electronics...

Well, our controllers can fully control a laptop, however, you will have to connect to the laptop's pushbutton. Likely this will require soldering wires onto the pins of that pushbutton.
