Hey guys ... and girls

I've got a problem that i'd like to get some help with.
I just bought a new laptop about a year ago and just recently i set up my laptop to use external speakers. Now when i plug in my speakers into my audio jack you can hear the audio .. same when i plug in my headphones..
but when i take out my headphones/speakers you can't hear any sound coming from my laptop speakers. Now i've gone through Control Panel and double/triple checked all of the settings and they still won't work.. if anybody can give me an idea about what is wrong or what step i should take it would be very helpful. (My laptop is made by Compac .. if that makes a difference....) I might not be on too much so forgive me if i don't reply to any questions...

Thanks
