I have a D443 (eMachines=Asus now) with a E450 and AMD Radeon HD6320 and it is a disaster.
It ONLY runs Windows.
That is to say I was after a lot of trials able to install Linux (most live cd's I tried simply didn't boot the thing) and then I thought "all fine" for a day or so as all was running and working fine.
However booting it up again after a shut down is the problem. It boots up to login and then simply hangs.
I set it up dual boot (as I was suspecting hardware problems) but it runs Windows 7 like a champion. Turns out a Linux unfriendly laptop and this one I would anyone advice to avoid.
I mean THIS ONE
Maybe you can compare specs.
I was mislead by the fact that I am using AMD since 1998 and it came pre-installed with a limited version of Linpus Linux. Turns out useless.
