    • The connector may be tight. Gently rock the connector from side to side while pulling directly upward to free it. You can use this technique on many of the cards and cables you'll be disconnecting.

    • Make sure you have removed the laptop battery and CD/DVD modules from the expansion bays before proceeding.

    • Remove the two silver Phillips #1 screws that attach the heat shield to the internal metal framework.

    • Lift the heat shield up and pull it toward you.

    On my M7572, these are T9s not Philips.

    • Skip this step if your computer does not have an Airport card installed.

    • Firmly grasp the plastic tab attached to the Airport card and pull up and then to the right.

    • The Airport card is still attached to the antenna cable, so don't just yank it out of the slot.

    On mine, the airport card had been put it with the orange ribbon OVER the top, so had to unplug the righthand connector and then plug it back in after (see pic for Step 8)

Frankly speaking I do not have idea why do I need steps 2-7 to replace battery? Why I can't go directly to step 8 if it is possible? BTW - the battery seems to be composed from 4 standard batteries. Is anyone aware how to assembly new battery? It is not available as spare part (616-0108)

Agreed, I just successfully removed my PRAM battery skipping all those steps, just popped the keyboard out, removed the DVD drive from the right-hand out and popped that bad boy out, no problemo.

I read that you "removed the DVD drive from the right-hand out...." I'm baffled as to what you mean or how that is done. Can you explain that step?

Scott Kohanek -

Why do I need to remove the airport card? It's just like telling somebody to remove their shoes to take off their hat?

Wish I had read the comments before proceeding. Just removed the Airport card and put it back in for no reason. Thanks for the instructions though.
