SL400 Screen noise

2009-10-20, 0:47 AM

I have the SL400 with the LED backlit display and it seems whenever I have the screen on (I sometimes use an external) that it makes a high pitched squeel like that of a capacitor under duress. It wasn't there when I got the laptop and it goes away when I have the screen off and only the external on.

My SL400 does the same but the noise comes from somewhere underneath the keyboard. I think that the processor is the perpetrator. Nonetheless, in your case it sounds like as if the internal circuitry of screen is the one to blame. Call lenovo to have it fixed.
