Anyone lucky enough to own a HP Pavilion dv7 series laptop knows how beautiful this machine is. What you may not know is the laptop motherboard part number in case something ever happens. I'm talking about 486542-001 and sometimes referred to as part #: 71CQ0132002.
HP show's these laptop motherboards to be "System board (Motherboard) - UMA architecture, supports AMD Turion 64 Dual-Core processor".
In addition to those details, this notebook systemboard included some extra goodies like two SATA HDD plugs, one USB port on board, one HDMI port, a expansion slot with card reader, web-cam capable and this part number used the AMD RX781NB/SB700 chipset.
I would also highly recommend that your computer currently has the 486542-001 inside because it does only work with HP Pavilion dv7, dv7-1000, dv7-1100, dv7z-1000, dv7z-1100 model AMD dual core laptop computers.
HELPFUL HINT: An easy way to do this is to turn your laptop over, remove the memory and the part number would be under there. Sometimes it is under the keyboard which you could find by unsnapping the notebook keyboard and reading the hp spares part number under it.
