I just added an extra 512Mb of memory and a DW1390 wireless card to my Acer Aspire One 150 netbook. Now it has 1.5G and the wireless works (ie. the old card disconnected often and did not work under OS-X). I am writing this blog post with the new, cute little machine.
I had two hard problems. The first was that I could not figure out how to hook up the antenna for the DW1390. It had two triangles colored black and white, and there where two cables, black and white. The problem was if I matched the cables to the colored triangles on the card, I would end up reversing the connections from the original card. Searching Google I found reference to a Samsung N10 where they said keep the connections the same as the original card (thus plugging the black cable into the white triangle and the white cable into the black triangle).
The next part had me sweating. All the guides imply the keyboard is hard to remove, but I had no problem I just pushed the tabs back and they stayed out of the way. Sadly this was because I had pushed them so far back that they twisted behind the case. Also sadly 1 of the 3 clips was BEHIND the LED light transport (which was melted into place, no removing it). With a razor, paper clip, and screw driver I was able to restore the position of the clips and have the keyboard snap in place securely. Word to the wise, DON’T push the clips into the case!
