Keyboard into Audacity

I thought it was time to try to record some of my keyboard efforts onto audacity.

There are about 4 ports on the back of my Casio … tried all
cable into my laptop…

got the audacity window up and hit the record button…

In the past Id hit the record button … say when playing internet radio … and the vertical line would move…
Id see the blue sound wave form etc

but this time … nothing

I tried every port but did nt see any kind of signal !

See here in the Frequently Asked Questions: http://manual.audacityteam.org/man/faq_recording_troubleshooting.html#keyboards

put a mic into the laptop and again… no signal appears in audacity …

Ive plugged it into the mic socket

window comes up I confirm … line in …

I assume the microphone option may be the built in mic in these lap tops
