No docs. But fortunately, HP has full maintainance docs available on 
line. I have them for both of my HP notebooks (nc4010 and nc2400). I had 
to take out EVERYTHING to get to the fan: hard and optical drives, 
memory, WiFi, Bluetooth, switchs, keyboard, case cover, display, and 
system board! Then I finally got to the fan and then reassemble and hope 
I got all those ribbons and connectors connected right. Took about 5 
hours (with 1 hour run to MicroCentor to get an T8 and T7 screwdriver, 
as my T8 socket was not long enough and did not catch in pre-reading the 
docs about the T7 screws). Fun. Not.

But, since this notebook 'died' the company wrote it off, and now it is 

Same with the nc4010 that had a broken display hindge. That was a LOT 
easier to repair.
