Try a hard reset.
remove the battery.
remove the ac adapter power.
press and hold the power button for ten seconds.
Replace the battery or pug in the ac adapter power and restart your laptop.
If that doesn't work try reseating your memory modules.

I'm sorry to say that you have joined the growing list of people with this model who have a paperweight.
Here are some of the symptoms:
- you plug in the power adapter, the power light at the adapter lights blue, the system receives a charge of power to the hard drive, DVD drive, fan, and then dead, pressing the power button does nothing. Power light stays on, but no more signs of life. You can repeat this little event by removing power and reconnecting. Notebook shows life of things starting *for a moment* without hitting any buttons, then goes dead, with light at power remaining as the only sign of inorganic life.
Here are things you can try to no avail:
- 'hard reset' by holding the power for 20 seconds with all power sources removed
- remove hard drive or memory
- remove wireless network adapter
Here are some other folks who have seen this happen
- F700 won't boot
- on then off
- dead f730us
- another one bites the dust
- sounds familiar
- replaced motherboard to solve
- laptop wont boot
- won't turn on
- This couldn't be all a coincidence....

Same symptoms ... no cure found. Very very frustrating...
The hard reset works most of the times... but not always. The wireless internet was gone exactly one year after purchase. Been using it with a wired-in internet cable ever since.
Symptoms of "Dead screen" began around the same time. Fortunately this is my second laptop. I would have gone mad if this was the only one I had...

After performing the hard reset and replaceing the battery pack and /or power supply, press and hold F10. It may have to be held for a minute or more, or it may have to be done several times. Eventually, the set-up program should start. After setting date and time, move to the diagnostics menu. Perform the hard drive diagnostics. There are two parts. "Quick" and "Comprehensive". It will pass the quick test and probably fail the comprehensive. However, it should see the OS, now, when you power up.
Basically, if this works, it means the BIOS is corrupt and needs to be flashed. Also, I think the chipset drivers will need to be re-installed. The BIOS and drivers can be down loaded from the support and drivers site. If you can't connect to the internet, you can download on another computer and transfer with a flash drive.
The reality of it is, it may possibly require a new motherboard. I hope this is helpful.

Thanks that I know about already been there tried that. I did that to keep it working for awhile. The thing is this issue is all over the web. HP knew this was a problem and they sold the laptops knowing this problem would happen. Before my laptop stop working it told me hardware issue, so I know it must the the mother board.
I had just put new memory in it, I tested memory, it's not that, so it must be again motherboard. I am not paying all that money to replace a motherboard when I can just buy a new laptop, another brand I know I wont have issues with. I researched this issue and read that even replacing motherboard, it's not a permanent fix, it will go out again because of the way it was built and that it getting over heated. Thanks~

Had same problem ( F730US) . Your screen is not dead.
Shut the computer down
Remove hardrive ( just unscrew the 2 screws, remove cover, and pull it up) and battery. Press the start button for a few seconds.
Restart on power. Screen now comes up and gives a message.
Install hard drive ( takes a minute)
PS It most likely will happen again at some point and time so just remove hard drive again momentarily.
