I have been delving into how to get this HP NC4010 to suspend. I think the practice of just closing the unit for 15+ min inside my backpack as I move to the next meeting is what cooked my drive... So it seems that Debian users have been successful with APM: http://www.proulx.com/~bob/nc4000/ and http://www.gag.com/~bdale/nc4000/ So my Centos related questions are: I need to turn acpi=off in the boot so I can turn on apm. How DO I turn on apm. I have a large enough swap drive. It is an LVM drive of 2Gb and I have 768Mb memory. The example given is: vmlinuz-2.6.8.1-1+8-686 root=/dev/hda5 ro acpi=off resume2=swap:/dev/hda1 My swap drive is: /dev/mapper/VolGroup00-LogVol00 what do I do above? and my root is /dev/mapper/VolGroup00-LogVol01 There are references to compling the kernel. Do I have to do that? Is that mkinitrd? what suspend command do I use? What do I loose giving up acpi? thanks. I am leaving for the RSA conference in San Fran tomorrow morning, so I would really like to get this going...
