    Hi.

    I just received my T400 in the mail yesterday. I spent the whole day updating the drivers/tweaking Vista for some performance etc... Everything was going fine before I updated my audio driver. For some reason my internal speaker keep on playing even when I plug a headphone into the headphone jack, and no sound would come out of the actual headphone itself.

    What do you think I should do? Roll back the drivers?


    Oh, and as a side note, I'm only getting about 3.5 hours of battery life with 6 cell battery and everything set to minimum... Is there some sort of Lenovo oriented battery life optimization guide on the forums?

    This might sound silly, but triple check you've pushed the headphoen plug all the way into the jack. If it isn't quite completely in, it can do this.

    If it is still a problem I would begin to suspect a hardware issue.

    I agree that it is a hardware issue ONLY if you had a problem with the headphones before you started tweaking the drivers. Restore your computer to a point in time when the headphones were working properly and see what happens.

    I can confirm that I have this problem too, and it is isolated to Vista. Sound plays fine through the speakers, but if headphones are present, all outputs are physically muted, but Vista recognizes the headphones are being active.

    I had something like that happen a couple of times the first couple of days and then it went away. Maybe it's more of a Vista thing, make sure you've gotten all the updates.

    This was happening to me as well. It seems to be working as expected now, so I guess it was a driver issue. Meanwhile, you can manually change the sound output source by going to Control Panel -> Sound and disabling/enabling the speakers or headphones, as you see fit.

    I had this same thing happen and I fixed it by updating the sound drivers through that Lenovo udpater program.

    EDIT: Actually, I should add that this started happening when I began uninstalling bloatware. I uninstalled that smart audio thing in the control panel and that's what caused it.

    Hmm. Tested with different headphones. This is definitely driver/Vista issue like most of you suggested. I'll try running Thinkpad updater again, and roll back the driver if the problem persists....


    Does anyone else find it annoying that you have to spend hours modifying the OS for it to do what it's supposed to do?
