HP Notebooks PCs - AC Adapter Makes Hissing and/or Crackling Noise, and May Feel Warm to Touch

Problème :
The AC Adapter of the HP or Compaq Notebook PC makes a hissing, and/or crackling noise and may feel warm to the touch.
This is more prevalent after the adapter has been connected to AC power for a period of time.
Solution
AC Power adapters do emit high frequency sounds (15 kHz-20 kHz) that may be misunderstood as hissing or crackling noise. This is normal and not an indication of a failing adapter.
The temperature of the adapter also may feel warm to the touch. This is normal operation too.
