I have seen a few posts claiming that upgrading the D270 ram has been deemed not user replaceable. Although Acer may have deemed it not user replaceable; it totally is. It was so easy. I switched out the standard 1GB of Ram for a 2GB stick in roughly 10mins.
Rukusone,k the maximum RAM supported by a Aspire One D270-1806 is 2 gigabytes. But before you despair, let me explain one of technology's deep, dark secrets.
Your rig has a dual-core CPU and two gigs of RAM. Except for a few high-end games, that is about as fast as any one program can go. Adding more RAM will improve your multi-tasking, but if you are using one program at a time (You actually have antivirus and other programs running in the background) you might see a small increase at speed at best.
