July 7, 2012 at 07:37:32
Specs: Windows 7
After changing HP G60 Notebook motherboard and HDD, I couldn't even go to BIOS setup screen.
When I turn on power, only "serial not found" message showed.
I tried to go to BIOS, I couldn't go to BIOS setup.
F9 and F10 key didn't work.
Can I put serial number on the notebook?
Please help me out to solve this problem..
Thank you.

You have not answered most of my questions !

"Also I change hdd, but not the same as I used, I just changed with one that I had before."

Does that hard drive have an existing software installation on it ?
If it DOES, the computer will probably NOT be able to fully load an existing operating system installation unless the hardware that was on the mboard when the operating system was installed is NOT more than a little different from the hardware on your present mboard.


If it was a used mboard, did it say in it's description the mboard you bought been TESTED and had been found to WORK ?

If pressing the F1 and F2 keys works, then pressing the F9 and F10 keys should work too, unless there's something wrong with the mboard or the built in keyboard.

The ability to respond to pressing those keys is built into the bios version.

Malfunctioning keys on built in keyboards on laptops or netbooks are very common. Try connecting a corded USB keyboard, then trying pressing F9 and F10.
........

Going by the vague info I've found so far regarding "serial not found" , you can get that message because of a hardware or a software problem.
Try removing the hard drive to see if your symptoms are any different.
If they aren't, you probably have a hardware problem. Make sure all connectors connected to the mboard, all cards plugged into it, are properly plugged in and fully seated, and that any cables are not physically damaged.

Why did you change the mboard ?

Was it because it wasn't working because of any of these things ? :

Have you, or is it possible someone else who had access to this computer...
- dropped it, or dropped anything on it, or otherwise exposed it to a physical jolt ?
- spilled liquid on it, or sprayed it with liquid, or exposed it to liquid such as rain ?

Since the computer last worked properly all the time, has there been a power failure event that happened while the AC adapter was plugged in ?

Those things are the most frequent reasons something inside the laptop has been damaged.
.......

Did the original mboard have a password that was set in the bios that you didn't know ?

If yes, was that password for hard drive access or system access?

Are you using the original hard drive, or one that was in a different brand name computer ?

Did you install a mboard that's identical to the original one, the same HP part number ?
Are you sure that that mboard has no passwords enabled in the bios ?

Searching the web with
"serial not found" HP notebook
or
"serial not found" HP laptop
doesn't find a lot of "hits" but most seem to be only for a problem with HP computers.

Are you sure it's exactly "serial not found" ?

If the more to the error message ?
If yes, qiote the entire message.

Try using an external USB corded keyboard.

This sounds like an effort to get a locked laptop running again. The cost is probably more than the unit was worth.

If the replacement motherboard was used it may well have an embedded password on it.

Thank you for reply,

I placed an order mboard as the same as I used on the hp web.
Also I change hdd, but not the same as I used, I just changed with one that I had before.
While booting up notebook, only F1 and F2 keys are working but F9(Select Boot) and F10(Enter Bios) didn't work.
I couldn't change boot option as a cd-rom.
This is really disappointing. If I can change the boot device, it would be great.
But I couldn't now.
The worst thing is mboard and hdd both corrupted at the same time.
I also can't run winphlash now.
Please let me know how can I log in BIOS.
Then I can boot up the laptop.
Thank you

Thank you for Tubesandwires.

I'm sorry that I couldn't reply to your question.

I figured it out with your answer. Really it works with USB keyboard.

Then I download HP DMI toolkit and solved the problems.

Thank you for your answer again.
