I also have the same laptop (and the same problem) and am willing to test fixes! I first noticed this when I switched the laptop from Linux, where I used to suspend with APM. When Anish helped me get ACPI suspend to work, I noticed that the battery drains much more quickly while suspended under FreeBSD than under APM suspend from Linux. (I can't compare to ACPI suspend under Linux, I was never able to get that work...) Ian
