Um caps lock key blinks twice when power is connected. Also screen is completly blank. No beeps. And when power is disconnected and reconnected the laptop powers on without having to press anything. But just powers nothing actually happens. I have tested other things and i now have win 7 installed on the hdd. The ram is fine and screen is fine. It was all going good before i did this so thats why i assuming the bios is deleted or currepted

Unpllug power and battery, hold Power button down 30 seconds. Then plug in power cord to see if anything changes.

You have to flash the BIOS chip on mobo to wipe or update it. If you didn't do that then you more likely changed a setting in your BIOS that is causing it's display not to work? Can you remember what you changed in BIOS, and if not why would you mess in the BIOS without specific instructions about what to do? It can be very unforgiving.

I think what I'd try next is to google your model for replacing CMOS battery or disassembly and then carefully remove the CMOS battery to reset the BIOS: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS

However this is so risky if you place any value on the laptop I would take it to a shop. Here in the states the Best Buy Geek Squad will run enough tests to tell you what the problem is before you even have to pay. I make an appt with them first so I can stand there at the counter to hear the results.

To be honest i dont really know what i did or how the issue arised from me trying to solve one thing and made life worse lol. It was a little wile ago i did this and just etting back to it now. I do remember that when i tried to swap between 8 and 7 it did come up with a bios error of some sort. And i have tried disconnecting power and coms bat as this solved the issue the fiart time but ive seemed to muck something else up now assuming its the bios and i have tried the coms bat again etc with no joy. Also im im NZ might give hp a cal sometime and ask them to

IF it is... and I suspect it's not, BIOS - then this will do the trick

If a BIOS corruption error occurs (Blink code 2), you may not even notice the blink codes, because as soon as the computer recognizes the error, it restarts, attempts to recover the BIOS, and then restarts again. You may notice an extra-long startup process as a result, and a message indicating that the BIOS has been recovered may display on startup. If this occurs, update the BIOS on the computer. For more information, see Updating the BIOS .

If the computer does not automatically recover the BIOS, manually perform a BIOS recovery by following these steps:

1.Turn off the computer.
2.Plug the notebook into power using the power adapter.
3.While the computer is still off:
a.Press and hold the Windows key and the B key at the same time, and then press and hold down the Power button on the notebook for one second.
b.Release the Power button and the keys.

By following these steps the BIOS will reach the EFI partition in order to recover the BIOS to the last known good version of the BIOS from the hard drive.

For information on how to restore the BIOS refer to the HP support document: HP Notebook PCs - Restoring the BIOS .

If this is a DIY downgrade from Win8 to Win7, how did you come by the Win7 license?

There are settings in BIOS that need to be disabled before attempting a downgrade
- the OEM is really the only entity that can provide the downgrade key (I think)
