  • Laptop - high pitched whistling sound

    Toshiba laptop - about 2 years old - it seems to be making a very high pitched whistling sound.

    I didn't notice at first as I have pretty bad tinnitus - down to ear surgery when I was a sprog I reckon - but it's definitely more noticeable as a different pitch of whistle than the usual noise I get 24/7.

    It's not speaker feedback because it does it with the speakers muted and the microphone isn't active. It's not the battery as it does it with the battery removed.

    Seems to kick in once it's been on for about 10 minutes, then does it all day. Sometimes varies in intensity. I have a suspicion the laptop is doing something fairly low key which is then triggering my own tinnitus so what I'm getting is amplified - the laptop may only be making a tiny noise which makes mine worse. But it didn't do until about a week or so ago.

    Any ideas?

      When my PC does certain things it makes a low volume squealing noise every now and then.

      It turns out it's the capacitors on my graphics card. When under certain types of load, they vibrate and make a weird noise.
      Forums suggested coating the graphics card in nail varnish to stop the vibrations but i left it as it is.

        Sorry - should have said, I know it's not the fan, that's running normally. It's like the kind of squeal you get from feedback but much higher pitch. My usual tinnitus noise is similar but slightly lower pitch, and I only get this higher pitch when the laptop is on.

        It's driving me mad.

              No - it is a much higher pitch and consistent. If you listen to a demonstration of tinnitus sound it's very similar - just a slightly different pitch to what I usually get.

                Does it do it when it's on your knee and only when I'm a certain position?

                  No - it's nearly always sat on my desk. The battery life on it has been useless from when it was new so I don't bother taking it anywhere with me. I have a tablet for carrying about.

                    Another off the wall idea from the green mouse.Power lead voltage transformer?You may have already eliminated this but in the absence of more expert advice its worth a thought. The fan is running normally,but have you checked its clean, especially if you have furry pets? If all else fails maybe opening it up,a thorough cleaning and checking components are properly seated might work. Bit of a chore and you would need to beware of static electricity. Hopefully others will have better ideas

                      I've tried it with the transformer unplugged, also with the transformer plugged in and the battery out - both of which are good ideas but neither of which seems to be the cause.

                      We have a fluffy bunny - but he's never allowed near my desk due to his habit of biting through wires.



                      I've given it a blast with an air duster all the same. (The laptop, not the bunny.)
