Can you check if this link exists?<br>
<br>
<a href="mailto:/etc/systemd/system/obmc-standby.target.wants/org.openbmc.buttons.Power@0.service">/etc/systemd/system/obmc-standby.target.wants/org.openbmc.buttons.Power@0.service</a><br>
<br>
That will start the service on the way to standby. If it does exist, then it should be running, so maybe check<br>
the journal for errors, or try running button_power.exe from the command line and see if it crashes.<br>
<br>
(can also check that the standby target was reached with systemctl status obmc-standby.target)<br>
<br>
If it doesn't exist, then you probably don't have </span><span style="color:windowtext;mso-fareast-language:EN-IN">OBMC_POWER_BUTTON_INSTANCES defined, though<br>
that should be in phosphor-defaults.inc. <br>

<p>Hi Maheswari,<o:p></o:p></p>
<p>I'm guessing you already have an <a href="mailto:org.openbmc.buttons.Power@0.service">
org.openbmc.buttons.Power@0.service</a> running.<o:p></o:p></p>
<p>You can check with:<o:p></o:p></p>
<p># systemctl status <a href="mailto:org.openbmc.buttons.Power@0.service">org.openbmc.buttons.Power@0.service</a>
<o:p></o:p></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-IN">or just check for the button_power.exe process already running.<br>
