I haven't done any hard tests yet, because I tend to use my computer at work, etc, but today my laptop slept for 12 hours and used at most 11% of the battery (it was at 89% when it woke up); based upon that information, I can naively assume that I should be able to get at least 109 hours (4.5 days) of suspend-to-RAM before completely draining the battery. I am not sure the battery was 100% charged when I started. If I do more precise testing or get more longterm data I will let you all know. Hopefully this is a useful data point for people. Good luck, -- Erik P.S. To be clear, this is a MBP C2D running 2.6.22.1-mactel, using a kernel configuration and ACPI setup which are basically identical to Ortwin Glueck's, running the Gentoo distro. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
