my dell inspiron n 5050 won't turn on. as i am a laptop technician(not very professional, but have some chip level knowledge), i tried by removing all power sources like battery, adaptor, cmos and draind residual power by holding power button for 20 seconds. then it's on, but within few seconds it will turn off. if again drain the residual power, then it will on and turn's off with in seconds. but one more thing is, if i install cmos batterry the mother board won't turn on even i drain the residual power, that draining residual power method works without the comos only. tried this somany times and same thing happend again and again . i noticed each time that is not turning off in exact time , but different, different timing. i am suspecting that could be bios problem but i didn't tried that, as i don't have bios programmer. i tried changing I/O controller, but the lappy condition is same. please some one help me with this

 How old is this laptop?  It might be time to buy another one because this sounds like a motherboard problem to me.  :dance:

Everyone with a computer should back his system up to an external hard drive regularly.  :thumbsup:

Remove all of the ram and try to power it on, do you get any post fault beep code?
