So, you can install OS from the recovery CDROM. This will make sure that you have your power management system is in place and you will be provided with APM options for syandby/hibernating/etc.<BR /><BR />-Ram<BR /> Thu, 23 Feb 2006 04:35:25 GMT https://community.hpe.com/t5/operating-system-microsoft/power-management/m-p/3736699#M7012 Ramaprasad N 2006-02-23T04:35:25Z
