Probably the lubricant on the speaker system plugs and jacks was a
mistake, but I suspect it would only result in intermittent operation.
I wouldn't worry too much about it until you get the computer/speakers
working, but wouldn't try it again!
You might also consider:
* Insure that it is the headphone jack rather than a mic jack that you
have plugged the speakers into.
* Has the laptop been taken apart where it is possible a jumper from the
headphone jack was not correctly plugged back into the motherboard when
the repairs were finished?
* Was the microphone jack physically damaged? Many times there is a
switch that is a part of the jack, so that when a plug is inserted it
disconnects the internal speaker. Are the switch contacts clean and
* Check the way that particular laptop was "supposed to work." There
may have been a software combination (function key, etc.) that would
activate the headphone. I don't have any experience with the Compaq
Presario V133CL. Without knowing, it is difficult to tell if it is
hardware or software.
