My Pavilion dv7 will not startup

HP Recommended
Pavilion dvy 4150ea
Microsoft Windows 7 (64-bit)

I tried to restore my laptop to factory settings but after restart it shut down and no longer start Up.

Have tried hard reset and all other key combinations to restart but nothing works.

When I press the power button, the f12 key and power light flashes once.

Also tried downloading new Bios file to another computer but protection system prevents running the .exe file

Please please help

Hi@Costa57, Welcome to the HP Support Community!

 

We have done the basic troubleshooting as  your computer .hence the Operating system is obsolete its end of support Life,

 

 

In the meantime, let's start off by performing a Hard reset on the Notebook:

Step 1: Performing a hard reset

Resetting the computer can resolve many issues that cause a blank screen. Use the steps in Performin...

 

Step 2: Connecting an external monitor to test the display

The notebook screen display might remain black when there is a corrupted graphics driver or a problem with the LCD display backlight. To test the display, attach an external monitor and restart the computer. Testing with an external display is helpful if the notebook display is black but you can hear sounds; such as fans, spinning drives, or beep tones that indicate the computer is operating.

 

Next thing, I would suggest here is to Run a System diagnostics test as well as an extensive test on the Hard drive and Memory from F2 (Please capture the failure ID for further assistance).

 

If all test pass turns off the computer.

As you turn it back on tap the F10 key. This will load the BIOS setup utility.
Press F9 to load defaults.
Press F10 to save and exit.

Hi

Thanks for reply, thats a lot of info to get through. However, since I have tried all the usual cures and resets for what to me now seems a hardware problem, I will focus on the hard drive, memory and motherboard.

Will let you know how I get on
