The HP Pavilion dv9000, dv9500, dv9600, dv9700 notebook PC is a excellent machine but unfortunately you may come across a laptop motherboard issues throughout the computers lifespan. From experience I know how frustrating finding the right part for your exact laptop could be a never ending task!
No worries though because if you look below you will see I've listed the specific dv9000 models that use this replacement notebook part.
If you own a dv9000 series laptop currently using the Intel Core 2 Duo chipset, then you'll need hp part number 447983-001 which in detail is the"Intel PM965 System board - With nVIDIA GeForce 8600M GS 256MB dedicated video graphics memory - For use only with model with discrete video system memory".
447983-001 has the following ports which should be the same as your current laptop board: 2 x SATA HDD plugs, 2 x USB ports and 1 x 1394 firewire, HDMI, LAN, a media card reader and has web camera with TV-Out connections.
When buying the new part, I highly recommend finding which version 8600M video card it has. This is important because G86-771-A2 is the new revision to the older nVIDIA GeForce 8600M G86-770-A2 GPU.
***This particular hp dv9000 motherboard part number supports the Intel Core 2 Duo CPU processors ONLY.***
***Make sure your laptop says one of the following series to ensure you will have no problem ordering a wrong p/n: HP Pavilion dv9500 CTO, dv9600, dv9640us, dv9700 and the dv9700t CTO Entertainment Notebook PC's.***
