My laptop won't turn on when I push the power button.

   then suggest heating it with a hairdryer for a minute or two thru the cooling vents incase its an open solder joint on the video chip due to overheating that is preventing power up.  immediately push power button after heating it up real good to see if it boots or tries to boot to desktop.

last thing to try is find the cmos battery and try and do a disconnect the short across the motherboard connector pins that the cmos battery attaches to.  try and  power up after reconnecting cmos battery.  report back with results.   

then yes  take your harddrive out and sell it on fleabay for parts       stay away from hPs     replace with a dell or toshiba, they seem to do a better job of designing them without quirky power on issues and most important is better cooling to prevent overheat issues with solder joints on mother board parts.

Manufacturers used to have instructions and labled contacts for clearing the CMOS and getting rid of a corrupted BIOS going back to the original basic one the Motherboard came with.  No longer, I guess people were fixing too many themselves.  Thanks for the tips, but I've tried every combination removing battery press power and hold, etc.  I've given up.

understand the frustration.   shoot send it to me for parts 🙂

This was really helpful thanks though do wonder what it is that affected it thanks again

something faulty with HPs sleep or standby power circuit design causes it to lockup in a state where it does noot want to  turn on or wake up with out taking some extreme meaures to unlock or reset it.   also their heat removal design at times seems to be very marginal with little to no added overtemp protection from damaging solderjoint ponts on key motherboard parts or damaging critical parts.

next time buy  a dell or toshiba.--my opinion only

Yeah, but when I worked at Wal-Mart selling Electronics, the worst, absolute worst, company for Customer Service was Dell, at least you don't have to speak a foreign language to talk to a HP Rep.

Regardless of what the HP tech support speaks. All I hear with your problem from them is crickets

[Bill_Patton]

I didn't mean HP was perfect, and I wish they would be more forth coming with solutions; instead of it having to be people that bought them to come up with answers through hours and hours of trial and error!  I want to be COMPUTING, NOT FIXING!  Where was their Beta Testing, where are theiir corrected BIOS versions?  I love HP products, but they need to admit to a problem and fix the darn thing.  Get over your ego and admit it's a problem and fix it already.  You have a product fan base, reward them with some support of what they've already bought!  Quit thinking of earlier models with problems as "Throw Aways".  Fix them, then we'll see what the new ones are like.

Mine is not under warrant because I had opened it to change the harddrive. I worked after but now it is now turning on... The light near the power supply in not going own tried to change power packs but still no sign

sorry to hear you have suffered the HP locked in sleep mode failure ...have you tried all the tricks suggested here.??  like 

remove battery and disconnect ac adapter  and hold power button down for two minutes in hopes of resetting something in the power down sleep mode logic that is hung up!!!   if you have tried this and reinserted the battery and tried to power up and still no Luck.  then what the lights if any come on when the power on button is depressed.   ??  does the caps lock

light come on or blink???  when ac adapter connected does the charge light show orange or amber??and if battery is fully charged does the charging light go white or blue??  do you hear the fan or harddrive try to spin up then shutdown??

you might try to locate the cmos battery and disconnect it  then with a flat blade screw driver try and short across the mother board connector pins for the cmos battery to try and reset the BIOS incase that is what is Honked up.  report back here with answers and results of your troubleshooting.  good luck  as you see from the forum responses  HP is no help at all.  they will just sell you another crappy product with no technical support unless you pay
