Problem with WOL after PowerOff without +5VSB

[reiner]

Hello,

My UIRT2B is working without any problems since 2 months now.
But I also noticed a little bug which was decribed already in another thread.

When I Power-Off the PC ( no +5V Standby ) I have to start the computer via
the Push-Button because WOL is not working. :(
After shutting down the computer without PowerOff, the WOL feature is working correct again.

Is there a solution to this bug(?) now ? FirmwareUpdate or something else ?

Hello,

It's nearly 1/2 year since my first post, but within the last
few weeks I had the chance to solve the problem by myself.

I don't use the WOL connection for POWER-ON the PC via remotecontrol anymore. I use WOL only for the Standby-Power.

New Solution for Power-UP : I put a relais ( G5V-1 5VDC ) at the OUTPUT1 of the UIRT2B together with the 'clamping diode' N4007. Then I connected the other side of the relais in parallel with the cable, which goes from the mainboard directly to the manuell PowerButton ( PowerButton is still working !) . The effect is when the relais gets power, it shorts the GND - PowerButton pins of the mainboard. Et voila, the computer starts. :lol: And it also starts after disconnecting completly from standbypower and turn on the main powerswitch again. ( This was the original problem)
Note : I learned the UIRT2B to send a pulse of 500ms to OUTPUT1 when pushing a specific button on my remote-control.
Another Note: Don't use a resistor at the OUTPUT1 of the UIRT2B, just connect it with a simple cable.

I only got a little problem when the computer is already running and I push the StartButton on my RemoteControl again. You remember, it's like pushing the manuell PowerSwitch at the computer directly. The computer powers off very quickly and at the next Bootprocess I got the 'wonderfull' blue screen with checking my HDD's. :cry:
But I could also solve this problem.
I just took a second relais ( same type G5V-1 5VDC ) and soldered it in series with the first one. The controlcircuit of the second relais is a simple 5V I took from a normal Powerconnector for a HDD/CD/etc. ( with a clamping diode N4007 ! ).
But a soldered the second relais in this way, that my PowerONCircuit only becomes closed, when the secónd relais has no power ( the computer is Off). As soon as the computer turns On, the second relais gets power but sets my PowerONCircuit off.

The result: When the computer is running, my push at the StartButton on my remotecontrol has no effect. :lol:
To be more specific: I can now PowerDown in a controlled way by closing all programms when pushing the 'StartButton' on the remotecontrol.


I hope that my explanation is not to difficult and easy to understand.
Perhaps it will help the one or other who is having also ( like me ) difficulties in that area.
If anyone would like to have the circuit in picture, please feel free to post.
But at the moment I have my circuit just on a simple piece of paper, not in
a digtal form.

normally you can connect the power-connector parallel to the case-switch without any relais.
the uirt has a connector for powering up the pc via the power-switch!
