Hp laptop charger is hot

"Im a 16 year old boy and my laptop charger is very hot. one day i was in my room and i saw that my laptop was no longer charging so i went to touch the charger and it was so hot i was almost burned so i let it cool down in a cool place my living room and it start working again but now its always hot and its making a buzzing noise is this safe for my laptop its only the middle part thats hot. not the tip of it are anything."

Solution:
"Many of HP's laptop power supplies get very hot when in use. I've never had a problem with mine, per se, but my girlfriend and her brother both have the same laptop, and theirs get as hot as mine. Her brother's stopped working one day, and I took it to my shop. It provided 18.5 (actually 18.87) volts perfectly fine under no load, but when plugged into the laptop, it would get hot and after about 5m, stop providing voltage. After getting inside (NOT an easy task) the problem appeared to be a group of solder joints that had, due to heat expansion and contraction, lost all but partial contact with the circuit. When the charger would get hot, the board would flex and the circuit would break. I haven't gotten around to it yet, but I should be able to fix the problem by resoldering the offending joints."

"It's unclear to me what exactly is hot. But anyhow, whether it is an "internal" (laptop) component that gets overheated or an external thing, you should go with your laptop and laptop power adaptor to get it serviced. You don't want to risk fire because of that. Especially if you smell that hot thing and feel funny odors. It could be a bad contact with the power line (bad dangerous plug in the wall), it could be a bad wire (that again dangerous as it could spark). You must get your pc checked by a specialist. Really."

"Get a new one, or if you have some technical know how you can unscrew the middle part and see what really wrong. Something has probably melted. I have two batteries and both of them I took to Britain and since then I noticed the hotness cause I just replaced the front wire with a british one. So ya Repleace it, try toget it fixed or fix it yourself. I can be dangerous."
