Hp pavilion modelp6510f press power switch on top of pc does not light computer fans blow but compute does not turn on

Try a Hard reset!

1. Remove all connections from the computer including the power cable
2. Press and hold the power button for 20-30 seconds and then release
3. Only hook up the mouse, keyboard, monitor and power cable
4. Turn the computer

let me know what happens!

check the fan and see if it is busted or any of the cables

Try swapping out the ram 1 at a time, making sure there is one memory piece there while testing. If no! check hard drive for activity.

old post, I do only 2018 posts)
first off why the huge contradiction even HP and ASUS mixed.
photo of laptop, and title, NOTEBOOK
and texting a Desktop, but must be a so i moved you....
p6126f PAVILION. it is. no monitor stated, at all. no errors show on monitor, like no signal?
the PC blue light means it thinks its one.
the fans must blow, both PSU and CPU or you have no 12vdc power.
the uSB ports have power, but that happens even with PC in standby mode, or even turned off, that is how I charge my cell phone PC off, using my USB ports,
what matters is:
1: monitor errors, seen
2: Fans.
3; you clicked shut down via what< windows, linux what?
if you CLICKED shut down and the fans don't go dead
that means your OS is corrupted. for sure.
top reasons are bad drivers, and vista can't shut down.
or worse. there is always that. (virus)

I'd DUMP vista, nobody on earth wants to help anyone with a dead vista , horrid VISTA, did you know MS in there great wisdom failed to add recovery mode to vista, yah sux, swap gas. that.
upgrade to w7 and end this silly mess called vista.
w7-64bit is best here, with full HP support seen here.


this is not spam, its the real HP, the place with no malware,etc.

Pull the power cord out and press the power button on the PC to drain the power for 10 seconds. Then plug the power cord back in and turn the computer on. If still does not work, then the power supply may be blown out and needs replacement.

test one do all Desktop fans run
if not the PSU is bad. 99% we can 1% if PSU is ok.

Remove the side-panel.
Press the POWER button.
Does the fan inside the power-supply start to spin?
Does the fan on top of the CPU start to spin?
Is there any lamp on the motherboard that lights up?
Is there any noise (from disk-drive, floppy-drive, CD-drive) ?

If not, take your computer to a computer store, and get them to replace the power-supply. Hint: the smaller the computer-store, the more-likely that they will install for FREE, if you BUY from them.

Nothing to worry, Open your laptop from the back side.Remove the RAM  and reinsert it.

Your system will work fine.

Most HP Notebook PCs have wireless devices built-in. To turn on the built-in device, simply press the wireless power button on your PC which will have the universal symbol for Wi-Fi (shown here on the left) and illuminate with a blue light.

Your power supply is bad--you will need to replace. I suggest looking at tigerdiect for a replacement.
