maybe a silly question, but have you checked if the contacts in the headphone jack are slightly bent? or corroded or dirty?
-if I understand you correctly, the built-in speakers don't work but headphones do, and partially inserting a headphone plug turns back on the built-in speakers? if so, I would suspect that the contact point inside the jack - the contact that's opened when headphones are inserted - may be causing you trouble, i.e. stuck open without the headphone inserted. I'm assuming here there's no fancy electronic switching between outputs; usually these headphone jacks are just mechanical switches.

if you open up your laptop, can you check the connectivity of all the jack's connections with a VOM?
another thing to try - perhaps try some electronic contact cleaner (the aerosol type) in case there's some corrosion on that contact causing the circuit to stay open without some pressure from your plug.
