I am running with the acpi_video patch, and I can have the laptop in S3 suspend for about a weekend. (This is with the high-cap main battery and an expansion bay battery, btw.) APM suspend indeed breaks something as I could never resume from it. There was a recent patch mentioned which I am planning to try as well. I know I should be able to achieve better suspended battery life, since I could go a week or two in APM suspend from Linux. (Before I get labelled a Linux troll, I'm a recent convert to FreeBSD on my laptop and like it a lot so far... slimmer memory footprint and much better documented. ACPI suspend never worked for me under Linux, so APM there is all I have to compare with. Battery drain under suspend means I have to carry around a power cord again, and that's no fun. I'm happy to test stuff as time permits.) Ian
