PowerUp with MS remote from Hibernate - solution

[Shadson]

Hello everybody,

My PC does not turn on with remote from Hibernate or power-down, Stand by is not suitable for me, so I spent two weeks in order to fix it and confirm to myself, that my hands still connected to the body in right place, not lower

May be somebody already did such solution, then you have an alternative.

It works with original MCE remote and turns on PC when you press Power button on remote. After the PC powered up you control it as always via MS receiver, this circuit will do nothing with your PC till you turn PC off.

The circuit is very simple, I spent about 5$ for all components:

It was my first project with AVR , so I used the simplest and easiest software I can find::

The prommer from 3 diodes and 6 resistors (supported by AlgorithmBuilder directly):

Btw, the debugging in AlgorithmBuilder is super, almost just like on PC, but be sure that you have installed external oscillator and have set the frequency very punctually in project.

During the flashing Attiny do not forget to set the fuses - CKDIV8 must be unprogrammed and CKSEL must be set to external oscillator >8MHz.

Source code (if you have other prommer- there is HEX-image for flashing inside):

Do not forget that +5Vcc must be even with turned off PC. On the modern motherboards it can be on PS/2 and/or USB (controlled by BIOS), on my MB I can get it only from WakeOnLAN jack. Check yourselves.

One more moment - the circuit gets from USB 5V for checking is the PC on. So if your motherboard keep USB power even in this state, connect this pin for example to 5V from HDD power jack (not to 12V ).

What is still in ToDo:
- it will be good to implment Idle or PowerDown, it can use 10-100 times less power during inactivity time, but it seems that after "sleep" command I got all the impulses together, like the are stored during sleep time. Will check.
- The box for circuit still not choosed I just wrap it into the cellophane and put in the case .

Who will use it please just write an email. I will know how much virtual beers I earned.

Good luck!
