Solved Replaced motherboad, How can I restore original HP logo and model No.?

[jorb]

Hello,

I replaced the motherboard in a HP Pavilion G62-407DX laptop. Specs
Now system info says its a Compaq Presario CQ62-417NR laptop. Specs
It boots up with the Compaq logo.
How can I restore original HP logo and model number?

Both motherboards are stamped DAOAX2MB6FO REV.F, HP part no. 592809-001
I used the original G62-407DX 2.60GHz AMD Phenom II P650 Processor 2MB L2 Cache on the replacement motherboard which had a 2.40GHz AMD V-Series Processor 512KB L2 Cache originally.

One board is stamped HannStar and the other has a CB logo (who ever that is)
Other than that the Processor locking mechanism is a little different (check picture) Kind of hard to see with heat sink attached.

Below:Picture of replacement motherboard.

Do I need to reflash the BIOS?

All computer functions are running correctly.
Other than a slightly dim display.

Any suggestion appreciated,

Thanks,

You could try calling HP technical support and ask them if there is a bios revision that will do what you want. HP has always been good at answering questions for me, when I have called them about my HP laptop.

I called HP and said that they could fix if I sent it them. Not just the motherboard the whole computer.
Not a feasible proposition.

I was looking at the specs and noticed the replacement motherboard also has less video memory.
Original MB G62-407DX Up to 1405MB of video memory
Replacement MB CQ62-417NR Up to 893MB of video memory
How can a motherboard have the same model number but different video memory?
Doesn't the BIOS have to be updated for the faster processor and less video memory?

I do not notice any degradation in performance.

Thanks for Reply,

They aren't the same model number, as you've shown. What it likely means is that since the part number is the same, one has replaced the other, and it may have dates stamped on it to show if you have a newer or older board. As for the video memory, that may potentially be changed in the BIOS.

If you get it to a point where only the logo is different, I would leave it alone. You only see that for a second or two when you boot.

Isn't this the part number DAOAX2MB6FO REV.F
If it is they are both the same on each MB.
Am I missing something?

Thanks

That's likely the part number. The model numbers you listed are different, and they boot with two different corporate logos, which means one board still came from Compaq. I was employed by HP during that whole acquisition, and there were many parts that shared the same part number because they were replacements of previous models.

What you are missing is that your boards aren't identical in some aspects, even if that just comes down to BIOS revisions.

Now you see why, when an OEM board dies and is out of warranty, most people scavange the parts and build their own computer with a standard motherboard. For the cost of OEM boards, you can do a lot more.
