Dont bother updating your bios unless you really want to. On my sager np8662 i went to all of the trouble of compiling and running my own DSDT, only to find that it had only two warnings and no errors. Basically like your suggesting (and unlike everyone else with this problem), the BIOS has very little to do with it. I run windows XP / windows 7 on my sager and it hasnt corrupted DSDT at all.
As for your fix, I havent tried using powermizer (or I'm just not realizing it), so I'm not sure what to tell you. So far (see above), I have been able to fix this problem by recompiling the stock kernel with ACPI_AC set to modular. This takes about an hour, so give yourself some time if you want to do it (I can post directions if you want, just let me know cause its pretty long winded). This causes the system to correctly report if the AC adapter is connected at the kernel level, so I would think this would solve your problem with the nvidia driver (since its at kernel level too). The only problem this creates is that if you recompile the kernel from the stock distribution (I grab the kernel conf from the ubuntu repo, change the flag and then recompile), the version number is the same. Update manager is going to nag you inscessantly to update your kernel since it doesnt match the newest kernel version. So far I use package holds as a workaround to stop the insanity (and believe you me its VERY annoying), but the correct way to do this would be to recompile the kernel with a new version number. Only problem is, I cant seem to find a way to do that (if you use the debian rules method included in the stock distro kernel, its supposed to do this automagically, but It never seems to work for me). Oh and also, I would stay away from openSUSE unless you want a boatload of video card problems. The distro is great, but for the life of me I couldn't get it to detect my nvidia 260M (a relative of your 9800). Who knows, you may have better luck, just a warning (ironically enough the AC module loads with the fewest edits on openSUSE, namely 0 - I think this has something to do with the init system they use, but it only causes different problems so its not much of a solution. Hope you like the nv driver... ^_^). -- ac adapter is not detected https://bugs.launchpad.net/bugs/412499 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
