Answer to: Can't remove screw from memory access doorI also had a problem with the screw. I finally got it out. When you're unscrewing it, it doesn't look like it's coming out or loosening up, but it is. The head still looks recessed in the hole. I finally got the panel out by sticking a nail file into one of the holes in the grating of the cover and the cover pulled right out. Once the panel was out, installing the memory was easy.
