Laptop makes a loud pop noise on boot up

[SHINRA-CORP]

I just got my laptop back from being fixed by HP for the third time and once again it's been given back to me with issues. When I press the power button theres a loud pop noise that comes from the back. It sounds like an electrical pop, like me pressing the power button has caused a spark or something. Anyone know what this might be and if it's something I can fix myself without sending back.

Should you not have this convasations with HP Support,

sense they just had it at support. ( also odd you should not mention this to them. and also look like fans kick in , but maybe a error with them ) im sure you can see a issue with give advice then you just had service on the laptop.


ps.
most here will never go up agaienst hands on gear tech person, then you need as you just point have a issue with things not there then laptop was new and it did not make such noise.
its here again should they not know this ? and did you point it out to them.

same as you dont argue with equal educated person , you need to catch him make a error before you do point it out. ( just like you post here for help now , you dont sounds happy about service they did. ) and what if they made a mistake or could not find the error before. so many things only you know from the dialog you had with them.
