You'll probably want to apply the acpi_video dpms patch that has been=20 floating around. It will mitigate some of the extra drain while=20 suspending issues. I don't suspend much anyway so for me it's not=20 much of a problem but I'd really like to figure it out. I think the=20 suspend issue might be specific to the 2110, as I haven't heard=20 anyone with a 2120 with that problem. ataidle also helps, to shut off the HD while it is idle. If you're=20 not using USB, Cardbus, firewire, etc don't load it, and make sure to=20 twiddle the pci power state sysctl. If you give it a go again, I'd love to know if your system exhibits=20 the power drain while suspended. eg. In windows I can leave the=20 laptop suspended for a day with only a percent or two drop, but in=20 =46reeBSD after 24 hours suspended the battery will be drained. I'm=20 pretty sure it's a driver issue, but without all the docs for the=20 components it's difficult to actually do anything about it. =2D-=20 Anish Mistry --nextPart2591287.gVQgvqy8lA Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (FreeBSD) iD8DBQBEaUAcxqA5ziudZT0RAuAZAKCW0QbOfQi2KOwBkVru2J8+KufVPgCgroP5 1vkKP8MFKGqSQZcDjLdNUNE= =KQAH -----END PGP SIGNATURE----- --nextPart2591287.gVQgvqy8lA--
