1st of all, I am acer laptop user, I strong recommend you go for ubuntu or kubuntu, this is the only distro can make your battery/ac_adapter sensor work. The fedora, suse, mandrake, yoper, centos, redhat, gentoo all need to work hard.
And ubuntu seems work well.. at least for me.
ps. my laptop is acer aspire 1680. Contact my msn
