It's a 2009 model so at 6 years it's an old laptop that is best not doing any investment on. You may get some coin by ebaying it as-is.
I was recently left with a non-functional HP Elitebook 8730w 17 inch laptop. This is an older model as it came with Vista on it but has some nice specs for an older unit. It is a 2.53GHZ Core 2 Duo and all with discrete NVIDIA graphics. I originally thought this might be related to the NVIDIA curse but don't think it is.
Diagnostic has revealed it is likely a power problem on the motherboard. I have worked on some in the past like this. It wont' charge the battery and the power lights at the lower left of the laptop just flash continuously. I found many references to this problem but no solutions besides replacing the board. I tried a different power cord and that didn't help.
I found the entire lower half of one of these laptops with ATI graphics for about $75. It is everything including the CPU but I would need to transfer the HDD, RAM, battery, and such to the new unit as well as the screen of course. This doesn't seem like a bad price but wanted to get opinions here if this model is flawed or not. I don't want to fix it and then have it die again.
