Mine still won't switch on. I'm going crazy now. Please help

please tell us the model numbr of the laptop you have,  remind us of all the troubleshooting steps you have tried to date, and why you feel like it is not a dead AC adapter, dead battery, bad dc jack on the laptop,  do you get any fan sounds or any lights on the keyboard or anywhere on the laptop   particularly around the dc jack.   

the more info you provide us forum folks,,,the better we might help.  forget about getting any kinda help from HP.

how old is your PC too?

I am also experiecing some problems. My laptop 15-e016TX was all gud working till yesterday evening. Then i has shut it down and went out. When i returned at night, i tried to open my laptop but didnt open. Neither it was charging from main power supply nor from the battery. It was totally dead. The tiny light besides the charge point was also not lighting. Please help me with these problem..

if the light by charge point is out   you need to verify that the ac adapter is working ...use a multimeter to probe the end to see that it has DC voltage or find a working ac adapter with same plug configuration and use it to see if it will power up the laptop.   post back with results.

The adapter is well and good. It is working. I have tested it with multimeter. And also tried another hp laptop adapter. Its not working.. laptop is dead

good to know.   so it the little led next to the power jack should come on then.   possibly you have a faulty dc jack but would like others to offer an opinion too.   

the other low likelihood possibility is that your video chip connections are lost due to overheating of the motherboard.  have you noticed any abnormal hot conditions while using the laptop last and you didnot run teh laptop with the cooling vents inadvertently blocked have you?   have you tried blowing out the cooling vents recently with a can of compressed air?   

any thing unusual about how it ran last time it worked--did it seem to run very slow?  if so,,a possible indication it was very hot in certain areas like either the cpu chip, the video chip or the ram!!

Thanks  for the information  ~ the motherboard was gone and had to be replaced. It was still under warranty.

When my wouldnt switch on the motherboard was gone and had to be replaced...

I guess little bit of heating is normal. And i always use laptop with the cooling pad below it. It was a bit slow when it opened. But after sometime it was normal again!!
But yes sometimes the CPU usage turns to 100 and then back to normal!!

Juli P   thanks for letting us know    glad it was still in warranty when it failed.   these HP laptops are poorly designed with regard to heat rejection.   you were very fortunate that it failed early.    now that its been fixed.  I would recommended using one of those cooling pads below it with the fans that help draw more air thru the laptop to assist with cooling them.   besides increasing its life....it may tend to run faster.  just a suggestion.  whatever caused the motherboard to fail the first time may still be present and hit you again.  again thanks for for letting the rest of us know your cause of failure.
