I don't recall hearing this before but tonight I noticed that there was a high pitch whine coming from the PDN, tried rebooting but still have it. Does anyone else hear/notice this? I have been taking allergy medicine so maybe I am just able to hear a little better today and this has always been there or maybe something is going bad???

Try different brightness settings - I've heard this when using Aldiko and dimming the brightness. A high-pitch but barely audible whine coming from the speakers.

OK I am guessing it was there all along. This morning I even heard some bats flying around so I think my hearing is just getting a little better on the higher frequencies. Maybe I should stop taking the meds so I am not annoyed by it.

[quote name='cosmos;49513]I hear it whenever I put my screen brightness at 40%... 20' date=' 60, 80, and 100 do not make this whine...[/QUOTE'] It was really high pitched so I ignored it. But thanks for the fix everyone.

SO far I have only tried 100% and that worked but would be nice if I could cut it back and save some battery.
