I have an HP Pavilion m6. My computer would not boot up. All it did was the power button would light up for 4 seconds and that was it. I installed a new motherboard and now it says boot device not found. I have another laptop exactly like this so I installed the harddrive and connector from that one, which definetly works, and I still get boot device not found. I did F2 and ran a hard disk check and it says there is not one installed. I ran memory test and it was fine. It will boot up from cd so I put my Windows 7 disk in but it won't install because it cannot find a hard drive. Any suggestions? I bought the motherboard on ebay which it said it was tested and working.
1) BIOS Setup states no harddrive found? Remove all power. AC adapter (Charger), and Battery. Remove Harddrive. Press Power On button in, hold in for 10 seconds, let go. Do this procedure 2 more times.
Reinstall Harddrive, and then Battery. Hook AC adapter again.
Harddrive recognized now?
You press the Power On button. This in turn presses against the Power On switch. The power is initialized. First chipset to receive power is the BIOS chipset. The Basic Input/Output System program is initialized. BIOS LOOKS TO SEE WHAT DEVICES ARE INSTALLED, does a Ram Memory count, and hands the computer over to the Operating System.
This is what I am basing the above on.
2) Not to knock sellers on Ebay, as I have found a few that are decent.
However the motherboard could be bad.
Harddrive controller could be bad.

3) Don't E-slap me, but you were wearing an ESD wrist strap, with it's alligator clip attached to a good ground source; when replacing the motherboard, correct?

Make sure there is nothing attached to the laptop,remove all devices like keyboard,mouse, flash drives and retry. If still having same error flip the laptop over and remove the battery and open up the 2 other compartments that have a screw holding them. One holds the memory modules and the other the hard drive, check and re seat all connections, then try again. If you still have the same error your hard drive is most likely failing,
Thanks for using FixYa

Have you tried resetting the BIOS defaults? In doing so, it will force IDE re-detection and often resolve vague boot issues.
