    i got the sound get going again (lot of screen action seems to trigger it, so maybe it is the screen?) and tried to record it via phone and vid cam.
    unfortunately, the fan noise masked the clicking noises so i had to ditch that effort. Then I got to thinking and gave ep121's own mic a try and lo and behold, crystal clear recording of the noise.

    Sounds mechanical, which rules out pretty much everything but the fan?

    My guess; it's the fan's bearings.

    Edit; have you been able to confirm for sure that the sound isn't emanating from the speakers themselves?

    At first sound, I thought it might be a bearing.
    But then you hear it click, and kinda reverb. If it were the bearing I wouldn't expect the reverb.

    Strange. Do your fans ramp up when under load?

    <....."seems to occur with constant screen changes".....>

    @ themike- are you shaking/rotating the slate to get that noise? Is it coming from the pen slot when the pen is removed?

    When I take the pen out, it makes a ball bearing like metallic clicking noise if shake the slate. Put the pen back in and shake, the noise goes away. I'm sure the noise I am hearing is coming from the pen holder when it's empty. At least mine is like that.

    Anyone else share similar results?

    That's exactly the sound my HP TM2 makes! :eek: I have a regular Hard Drive, though. I always thought it was the HD, but now I doubt the HD is the culprit. I don't think it's the fan either.

    fan does ramp up accordingly to the load on the processor... no rattles when shaking the tablet... i'm starting to suspect it's some kind of electrical charge. As someone mentioned it in the past, it only occurs at landscape mode from the left side, so that leaves the pen holder out. The unit has been shipped to asus and back and seeing how they opened and closed it back up, i don't think it's some loose part. I'm seeing a correlation between screen activity with the sound (ie. scrolling up and down on freshly loaded pages) so maybe some faulty screen unit?

    It does sound the same, but a lot more frequent.
