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

quite fortunate it failed within the warranty period.   hopefully you got them HP to fix after you attempted all their suggested solutins besides holding your mouth the right way.   pray it does not fail even worse next time.  make sure to back up your important files incase you have to buy a dell or toshiba as a replacement for these unreliable HPs.

I have a HP Chromebook 14 model q010dx. It was working fine last night, left it on sleep mode to charge my phone and today it won't power on, only turns on the fan. Initially it had the yellow/amber light when I charged it but it went to white so believe it's charged. I tried holding the power button and also the refresh and power button but to no avail. Any advice would be greatly appreciated

It's back to amber light. The minute I unplug it dies so should be a battery correct?

Not so sure Seems like it should still turn on with the charger plugged in unless it really the charger that has failed. Doubt battery is easily removable! To test with AC charger alone

my laptop will not turn on. i have tried to remove the battry and connect the AC power to it and it will not power up. I have had this computer since 07/2014 when i got it for my Vocational Rehab. I do not know it is still under warranty.

Sorry. Out of HPs warranty since July. 2015. Unless the credit card it was bought with provides an extra year of warranty. Check into that with card company! The card company will help you get it fixed ur replaced if still covered by their extra 1 year warranty. Do you know for sure the AC charger is good?? Is the battery really charged? Give us more info on whether there are any lights at all on? Do you hear cooling fan running?

I've tried that method but I think something else is going on.  When I press the power button the light flashes once and the Wi-Fi "Amber" light flashes once.  It's probably some sort of troubleshooting indicator meant to lead you off in a certain direction that something was wrong when it tried to Post, but I can't find a reference for what it means.

Bill does the hard drive sound like it spins up at all. Any fan startup sound??? What is the model number ?? Any thing odd about how it shutdown last? Have you tried removing all memory sticks to see if it would boot up further in power on self test sequence?? HPs are bad. About randomly locking up in some unknown so ate of sleep! B

I had recently purchased a similar model and am listing it to sell.  I removed the Motherboard from that one and put in this one, so I've eliminated several items it could be.  The drive is fine, swapped memory and it's fine, and I tried a different palmrest with a different power ribbon board.  I believe I'm down to the CPU or the Motherboard.  Any ideas?

[Bill_Patton]

Forgot to mention: no hard drive or fan activity at all.  So I'm thinking something on the Motherboard or the CPU has failed.  That's pretty much as deep as my training goes.  Swap parts, if it doesn't work, it's a doorstop!
