Again, > good work! You probably *are* experiencing character loss. I still haven't fixed the problem that low-level EC access can sometimes lead to lost interrupts. I've tried to mitigate the problem by putting a 1ms sleep after each access, but that isn't perfect. However, I'm glad you're getting consistent results with the i2c method. > > While we're at it -- did you manage to control the fans?

BTW, a warning for those with Smart Batteries (or, for that mattery, any LiIon battery): you can damage your battery by running it all the way to empty. I kind of knew about this already, from stuff I'd read on the internet; but I got a nasty reminder last night. I ran my battery to empty, to see which smart battery alarms went off (disappointing; there were no alarms triggered, and only a single warning flag was set ~5 secs before empty). Unfortunately, this procedure led to the loss of ~3% of my battery capacity. Maybe when I get the in-the-works SourceForge project going, I'll set up a PayPal donation fund for a new battery :). cheers, Rich PS Overnight, I got a number of new DSDTs from various people; I'll be fixing these today and posting them on the website. ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
