Laptop shutting down while booting

[Mihirsharma64]

Heyy everybody..i have hp notebook 15 laptop ..it has recently started to shut down while booting and i m not able to boot into windows...when it starts it shuts down after 3-4 seconds..i have tried removing hard disk and then running and also replacing the ram..but its still the same..i have also cleaned the fan..but the laptop still shuts down..
I have noticed while taking wlan card apart is that one of its chip(the golden one) is coloured brown as if its burnt or short circuit(i m not getting the right word)...can this be the problem?can i try running the laptop without wlan card by removing antenna cable from the card and detaching it??

yes you can, just remove the power & battery first. Then make sure the loose antenna connectors do not touch anything on the motherbd when you turn it back on.
