Yes, it is enabled. But I'm not sure it is working. bash-3.00$ grep -v ^# /etc/power.conf device-dependency-property removable-media /dev/fb autopm default autoshutdown 30 9:00 9:00 default The powerd daemon (/usr/lib/power/powerd) is running. But it is certainly not shutting down after 30 mins. I'm a bit confused by this in the power.conf man page: " Device Power Management entries are only effective if there is no user process controlling the device directly. For example, X Windows systems directly control frame buffers. The entries in the power.conf file are effective only when X Windows is not running. " The sentance "The entries in the power.conf file are effective only when X Windows is not running." says it will not work if X is running. Given 99% if users are going to use X, that means the power management will almost never work. Or is that *supposed* to me the framebuffer entries will not work if X is running? If so, the word framebuffer should be inserted in the man page. (I also think graphics card or graphics chipset too, since few users of only Solaris x86 will know what a framebuffer is. As a SPARC user, I do. ). *IF* it is supposed to mean only the framebuffer related entries do not work, perhaps something like: "Device Power Management entries are only effective if there is no user process controlling the device directly. For example, X Windows systems directly control graphics card or graphics chipsets (framebuffers on SPARC hardware). The graphics entries in the power.conf file are effective only when X Windows is not running." Or if it really means all entries are disabled, then perhaps something like: "Device Power Management entries are only effective if there is no user process controlling the device directly. For example, X Windows systems directly control graphics card or graphics chipsets (framebuffers on SPARC hardware). All entries (not just those related to graphics) are ignored when X Windows is running." Perhaps I am being thick, but it is a bit confusing to me. Perhaps I should submit this as an RFE. One more thing. I think it would be useful if there was a forum specifically addressing laptop users. I run Solaris 10 update 4 on my Blade 2000 and Solaris Express Developer Edition 9/07 snv_70b X86 on my laptop. I have a completely different set of issues on the laptop, which are very much going to be specific to laptop users.
