Can Carnetix turn your laptop on/off? I'm not quite sure what it means in the instructions, so is a second device necessary, such as this:
YES... soldering the power switch leads IS still required.
the Carnetix units have 2 wires from the "ACPI relay". those 2 wires are the switch contacts of the relay. you need to connect/solder those wires to the power button leads.
if a docking station is available for your model laptop and has a power button, then it may be easier to solder that switch instead
Fusion you have been more than helpful and simplified understanding this alot for me. Thank you.
