Should I worry about my laptop?

Yesterday I was on my laptop with it plugged in and I noticed a horrible burning smell. So I turned it off until it was cool. Then I turned it on again and it got hot and stinky again. Then the light on the charger went out, so I unplugged it and then plugged it in and then it started to smoke. So I of course grabbed it out and shut down the computer. Later I started up the computer without the charger and it works fine and it no longer smells or is overheated. There is a USB port in the cable too which I usually stick my phone cable into and my phone won't charge with it either, so I figure the charging cable was the problem. HOWEVER the "charging hole" still smells, and when I talked to IT on the phone they said my charging hole might be permanently damaged. Somebody's going to come by today to check, but in the meantime what do you guys think?
