ok, works. but why are steps 24 thru 26 necessary? I did not remove the DC cable and it worked out anyway. Why should one remove it? Otherwise, everything turned out to be exactly as described, except the screw in step 33, next to the display, it was not there, but a different screw in a different place. I left it, bent up the shield carefully to access the HD. Used a Linux based machine to dd the old 40GB Fujitsu MHT2040AT drive to a 64GB Supertalent IDE SSD FHM64GW25H, which might waste some 15GB of the new device, but with no TRIM command around it's a good idea to keep the SSD partially unused for performance reasons.
