Is there anything I can do to stop the hissing?
So I've now found some time to look into this more:
- the problem remains when I remove the wireless card (so leaving only
the CompactFlash card installed).
- the problem does not change in any way if
My 5501 has the same configuration as Jan's, and I am unable to notice any
noise at all. The last time I checked my hearing it went up to 18kHz in the
good ear. So I am having difficulty understanding why Jan is experiencing
this noise and especially noise at such a high level. And the fact that
check any SMPS sections.

Jan,
It is more likely that the noise you are hearing is coming from the
magnetics rather than from any capacitors. There are planar
transformers in the switching power supply and the Ethernet interface.

Sometimes the transformer core material has a natural frequency harmonic
