Yeah it is ubuntu related, all sony vaio threads indicate that vaio have acpi issues on ubuntu, somehow it just doesn't install properly. If I boot the kernel in recovery mode though, I get ACPI mounted and I can shutdown normally without a hard-power down. Is there no one in the entire linux community that can help me with this issue. All I have done so far is scour forums for days on end. This is one reason why Microsoft dominates. Not many people want to spend the time searching for solutions. I have used ubuntu, knoppix & redhat and I am now thoroughly a linux convert. You simply cannot reproduce this functionality in another OS. I just want to be able to get my laptop fully running so I can convert my entire family and then go on to deploying this great OS on my work desktops. Someone out there please help.

Thanks for replying what I ended up doing awhile ago is formating my hardrive re-install ubuntu without the power cord attached that seemed to fix the acpi issues. I now have a working battery and adapter reading. The only problem is if I allow the kernel to boot it get this error acpi_ec_wait timeout so I end up always having to select to recovery mode option. When editing the boot file and adding the line acpi=off it boots fine with no errors but of course I cannot see battery or adapter states. Recovery mode works i.e. or adding the same options to the main kernel but it doesn't auto load you have to keep selecting boot preferences. Any ideas?

Does this happen on other distros ? Try a live CD like knoppix, does it happen there ? If not then this is an Ubuntu bug.

I have tested Ubuntu/Kubuntu and reproduced the error in a live boot, I have also tested opensuse11 and it works fine the distro is just too bloated for my uses though so I went right back to Ubuntu this OS is really impressive. So far, I have managed to boot up ONLY by allowing it to start the boot process on battery only and then connecting the power adapter when it is half-way through its cycle. I really would appreciate a more intellectual fix from the community though.

If you want my opinion, this kinda stuff is usually caused by a poorly configured kernel. So if you have the courage to build yourself a new one, it'll probably fix it.

If you want more help from the community, I guarantee you you will get more at the Ubuntu forums, all the Ubuntu users go there with their problems, I mean why not, it's the official forum after all.

I like this forum and i would love to come hare for more discussion being active member.
