I have a Thinkpad 600 and my Labtec LVA-8450 headset won't work. Do you think I need the Andrea P100 Power Plug Adapter also?

  I also have a TP 570 and encountered the same problem with the
  microphone/headset, Andrea ANC-600, that I ordered from Speech
  Controlled Computer Systems. Going by the information in the
  SCCS and Andrea (www.andreaelectronics.com) web sites, I
  ordered the Thinkpad Adapter (Andrea T100) along with the
  headset.

  However, the Thinkpad Adapter didn't work with the TP 570 because
  the TP570 doesn't have the metal outer shell power tap present on
  some earlier TPs. Instead, the TP 570 is "SoundBlaster compatible",
  which I guess means that the power tap is the tip of the microphone
  jack. To use this, you need the Andrea P100 Power Plug Adapter,
  which came free with the ANC-600 that I ordered from SCCS.
  Using the P100 on the microphone input, the microphone worked fine.

  Hope this helps.
