How to start a PC without a button

Brando9 You
cannot turn on the power from the keyboard or mouse.
The bottom line is that the Power button physically closes the contacts that give an impulse causing a reaction. A type of starter in a car.

If the button on the case does not work (and you are sure of it), then there is a way to turn on the computer without it - to close the contacts on the motherboard manually (with a thin screwdriver, for example). Well, or you can, as in the best traditions of militants, tear off the wires leading to the button, strip them and close them))) However, you need to be careful and careful. Especially if you tear off the wires ...

Below is a diagram of what to close:



You need to find the PWRSW connectors, disconnect the wires coming from them and close the PWR and Ground ~ contacts for one second (I circled in green).

Here is a link to the description of the motherboard in English: http://www.manualslib.com/manual/414969/Asus-M5a97-Le-R2-0.html?page=38

Naturally, everything you do, you do on your own fear and risk. Responsibility for the consequences will remain with you))

I agree. You can also connect the reset button to the power button contacts and start the computer from it to make it more convenient.

Thanks for the answer, it is a pity of course that is impossible, I somehow run it peremykaya wiring, I trick from is key, so that in principle the rules just like to poestetichnee, and then the whole thing sticking out))

possible, but whereas in the case of wild freeze, I can not even reboot normally

Brando9
Why, turn it off and on, that's all.

With the RESET button, it's a good alternative. In the event of a freeze, a 4-second hold of the Power button will turn off the computer, if anything.

Ok, thanks guys, I'll try with a reset!

Brando9
Then write whether it worked or not. Good luck.

bazilews I
did everything, a minute's work, I plugged the connector from the button into the socket for the power button on the motherboard, everything works! Thank you again for your help, I would give you a plus, but this gratitude system is absent here))

Not at all. If you still have problems, contact us.

Maybe you, of course, disassembled the computer and know better (or I don’t know what the starter does except the start). But I remember exactly that the power button puts the computer in the "on" state, which does not disappear when the light is turned off.

You probably confuse a short-term voltage surge with a complete blackout.
In the power supplies, there is a special relay that, in the event of a voltage surge, turns off the power from some computer nodes so that they do not burn out, and the computer goes into reboot.

The bottom line is that the button works according to a certain (flashed in ROM) algorithm: if the Button is pressed and released, then there is a reaction to the power supply, if, during the working state (with the computer turned on), the contact is closed and held for 4 seconds, the shutdown command is given, if close for 1 second, then on different BIOS there may be a different reaction or Reset, or hibernation.

If the computer is completely de-energized, the "button readings" state returns to the Off mode. Try to turn off the Power supply while the computer is running (if you have a button on it), and turn it on after 3 seconds. After that, your computer will not automatically boot, it will be "turned off".

You can configure the inclusion of a PC through a router via a LAN cable. I just don't remember how
