First try a hard reset.
1. Remove the battery and unplug the DC power adapter.
2. Press and hold the power button for more than fifteen seconds.
3. Plug in the DC power adapter (leave the battery out for now)
4. Press the power button.
If that does not help, unfortunately you you have reached a point where only a shop or service center capable of reprogramming and/or replacing the BIOS chip can help. You can contact HP phone support about repairs at 1-800-474-6836 if you are in the United States.

While I was flashing the newest bios the laptop turned off in the middle of it, and yes the power cable was plugged in the whole time and was provided with power. Therefore I believe the bios needs to be reflashed, so far I have found that if I turn on the notebook with the windows key and B held down I get beeps and usb gets accessed too.
As I understand there is a crisis bios recovery I could do if that hasn't been destroyed. But what I need to know is which bios file I use from the notebook's download page, what do I name it and what size and filesystem does the usb have to be. I'm hopeing that will fix it and I wont need to get the bios replaced.
Thank You, much appreciate all the help.

This procedure worked to recover my dv7-2270us.
I also had to try a couple of USB sticks to get it to work.
Please note that when it is working, a USB stick with a light will flash to indicate use, the monitor will be black with no indications, and it will beep. A lot. As in don't do this near other people. I think my system took a little over 5 minutes of reptitive beeping (not at a completly consistent rate to keep you on your toes!). But then it stopped and powered itself off and all was good with the world.
Yeah!

try with the UEFI Support Enviroment 5.4.3.0 A
had some trouble finding the driver page for that laptop, is this the one? it's important to make sure you have the correct bios file. Also try to use a small capacity usb if you have one (1GB - 4GB), and if it has a small light on it is very helpful to see if it gets accessed. The usb needs to be in FAT32 format.
if that is the correct file then the bios should be named 3602 or 3603, follow the instructions again and maybe have copies of that file with the extentions .fd, .bin and .rom in those directories.
if it's the correct one hopefully it should pick up 1 of those files.
hope that's helpful

fortunatelly i managed to solve the problem!!!
The correct way is to rename the file 3602***.fd to 3603
I had in my usb 4 files:
3603.fd (formelly 3602***.fd)
3603.bin
3603.rom
3603 (without extention)
I followed the procedure (win+B key)... , the pc turned off by itself. When i turn it back on all was ok!!
Thanks for all the help!
