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.

On my M7572, these are T9s not Philips.

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)
