I just bought a new computer (Lenovo Yoga 13, with integrated graphics and SSD).
Whenever I bring it out of sleep, or do something resource-intensive (such as heavy Photoshop work), I hear a scratchy ticking/clicking sound. Similar to the sound of an old hard drive writing data... except this computer doesn't have a spinning hard drive.
Sounds similar to this: http://www.youtube.com/watch?v=1FdCKZ8qaUU
Is it the same problem? Coil whine? Coil whine has been noted for this machine by other users, and I believe I have a minor affliction of that as well. But this sound is quite noticeable and not especially high-frequency.
I've read that Intel ix processors can produce this sound when they enter certain C-states. Should I request an exchange/repair? Would the new unit be any different (in other words, is this a defect or design flaw)?
If I choose to stick with this model of computer, must I just live with the noise? Would disabling power-conserving C-states have a profound effect on battery life or processor longevity?
