My friends hp pavillion dv9930 just died, consequence of the whole hp naughty doings with their pavillion series.

He wants me to get a new mobo instead of buying a new computer.

I'm confused regarding the part because I find stuff like this on ebay and other websites:

"Replacement motherboard for dv9000 series, dv9500, dv9(you name it)."

Will then that motherboard work with ANY dv9000's? It confuses me that first they say any 9000 series model and then they list a few specifics. Don't want to order the wrong one and then have to deal with the whole "as is, no return, you should have checked first" etc. stuff.

Thank you!

Short answer: no — “dv9000 series” is a chassis/family name, not a guarantee that every board is interchangeable. Different dv9xxx models can use different chipsets, CPU/GPU packages, memory types and connector layouts, so you need to match the exact motherboard/HP spare number rather than relying on a generic listing.

Practical checklist to follow (builds on and ’s suggestions):

  • Find the laptop’s exact product/service tag and the board part number (the OP located theirs under the RAM). Use those exact numbers when shopping.
  • Ask any seller to provide a clear photo of the board label and the connector edge — compare labels and the physical layout (power jack location, display ribbon, SATA connector, number/type of SODIMM slots, fan/heatpipe mounting holes).
  • Verify CPU/chipset family and RAM type (DDR2 vs DDR3) — laptops typically have BGA (soldered) CPUs, so a replacement board normally brings the CPU with it. Don’t assume upgradeability.
  • Prefer listings marked “tested working” and with a reasonable return policy; request photos and the seller’s tested steps.

Basic testing when the replacement arrives:

  • Keep screws and cables organized and take photos during removal.
  • Boot with minimal parts: one known-good stick of RAM, AC adapter (remove battery/HDD). Look for fan spin, LEDs, BIOS/POST, or external display output. If nothing, re-check connector seating and CMOS battery; document failures for return claims.

If the board number you ordered matches the board you removed (as you noted), chances are good you have the right part. If problems remain, rule out power adapter, RAM, or display cable issues before assuming the replacement is bad.

No, some of them use different processors and thus architecture. If you think you have found what you need, double-check compatibility by comparing downloadable service manuals, or ask HP which one you need

try searching with the full model number on the bottom of the laptop ,
should look something like this .
dv9930US (FE779UA)

...and that is an even better idea... :)

Actually, found the part number for the mobo right under the RAM. The mobo is now on its way.
Thank you!
