Hi all, I wanted to exchange the HDD of the Acer Aspire One 531, but there is no dedicated hatch like for memory on the back. Searching the web and the forum here I couldn't find anything. Is there any howto to open up the 531 to change the HDD without breaking it? I removed all the bottom screws, but still the bottom of the netbook does not lift off. And I do not want to force is too much... Could you please help me? Many thanks, frankomat
