t30 screen is buzzing slightly...

[wrybread]

My t30's screen is making a little buzzing noise. It's very slight, I can't hear it unless it's late at night, but it's really annoying when I can hear it. Interestingly it goes away while I move windows around the screen, but comes right back when motion stops. Of course it also goes away if I turn off the monitor.

Sounds sort of like a mosquito.

Does anyone have a theory on this by chance?

I don't know if this would work, as it is on an LCD, but when one of my screens was buzzing it needed the refresh rate increased. Make sure your refresh rate is set to 60 (no higher or lower) and can you tell me if the screen buzz changes when you change the brightness and if it buzzes in the BIOS?

Hope this helps!

AFAIK, t30's screen doen't support "real" refresh rates other than 60Hz - it can be verified through any fast directx-test with "vsync on".

Screen buzzling is a well-known issue with a TFT mobile phones, RAZRv3, for example, but I never heard it in a t30, or other laptops.
In other hand, there are many things that can make the same noise - speakers, hard drives, even AC adaptors.
Are you sure that it's a screen? Do the noise remains after Fn+F7 ?

Ujav asked a good question. Does the noise remain when you Fn+F7???

Does the noise cause any abnormalities on the LCD???

Is the noise coming from the lower right-hand corner of the LCD???

Good luck.
