You'll probably want to apply the acpi_video dpms patch that has been floating around. It will mitigate some of the extra drain while suspending issues. I don't suspend much anyway so for me it's not much of a problem but I'd really like to figure it out. I think the suspend issue might be specific to the 2110, as I haven't heard anyone with a 2120 with that problem. ataidle also helps, to shut off the HD while it is idle. If you're not using USB, Cardbus, firewire, etc don't load it, and make sure to twiddle the pci power state sysctl. If you give it a go again, I'd love to know if your system exhibits the power drain while suspended. eg. In windows I can leave the laptop suspended for a day with only a percent or two drop, but in FreeBSD after 24 hours suspended the battery will be drained. I'm pretty sure it's a driver issue, but without all the docs for the components it's difficult to actually do anything about it. -- Anish Mistry [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (FreeBSD) iD8DBQBEaUAcxqA5ziudZT0RAuAZAKCW0QbOfQi2KOwBkVru2J8+KufVPgCgroP5 1vkKP8MFKGqSQZcDjLdNUNE= =KQAH -----END PGP SIGNATURE-----
