It is doubtful that you will find any "alternative" motherboard that will fit.

Have you downloaded, installed, and run the free SPECCY software?

It will show the "manufacturer" and "model-number".

Some laptop computers have a removable battery.

If so, remove the battery, and look for a label, showing the serial-number, inside the battery-bay.

Many folks posting here seem to think that replacing a laptop motherboard, apart from having to disassemble the laptop, is a simple matter like replacing a memory stick or a disk drive.

It is NOT!!!

Before you spend any money to attempt to replace the HP motherboard, you need to be aware of the issues involved with doing that.

First, HP does not sell laptop motherboards except for rare exceptions. If you use this link to go to the HP site and do NOT see your motherboard listed, that means HP does not sell it: http://support.hp.com/us-en/product/HP-Pavilion-dv6-6c00-Entertainment-Notebook-PC-series/5191856/mo...

That means any motherboard you buy will be USED, having been taken from another PC. Those often do not work, or have internal problems that the seller does not disclose. So, you need to buy it from a seller that will refund your money if the motherboard does not work properly -- many of them will NOT do this because the item is USED.

Also, the licensed Windows version that came preloaded on your PC is an HP OEM Version -- and that license is tied to the original motherboard, not to the PC owner. When you toss away that motherboard, you toss away the license -- and HP will not provide you a second license. Since the versions of Windows you can buy will not activate with the embedded HP OEM license, you will have to buy a Retail version of Windows, and a license to go with it. You will then have to replace the installed Windows version on your laptop with the version you bought and license it. We are not able to assist in any of that work.

The bottom line is the process is a lot more difficult than simply swapping one part for another.

Find it on ebay.

Before opening the laptop google if it is safe to open it. Some laptop enclosures are made with plastic clips which will break when you are opening it and you may need much more parts.

OK. I replaced the motherboard with a brand new one and after a few minutes the computer turns off. I assume it has to do with the RTC battery charging? I have a Windows 10 Flash Drive version with a license. But, how can I load it if the does not power up? I'am letting the RTC battery charge and hopefully it will turn on BIOS. Any suggestions would greatly be appreciated!
