Quick question . . are you dual booting to Wind***? And if so, when you check the battery status in Start/Programs/Acer/Acer Power (or 'control panel/power options/power meter'), what status does it give for the battery? (click on the battery icon)? Does it give a proper ID tag? I've come across certain Acer Notebooks that have batteries that hinder detection without the ID tag. Shows 100% charged, but, when the owner boots, they get prompted to connect to a power supply, then get a 'battery discharged.' error, and 'cannot boot until power supply is connected!'. Reboot again, then everything is fine, suspend works, even hibernation ?
I've ordered replacement batteries for a few of them, which work perfectly for about 4-6 weeks, then become as useless as the one they replaced, even though the Acer Notebook keeps chugging along just fine!!!
I don't want to rain, but there may be someone that has a better experience to share, so take heart . . . you'll save on power!
. . .
, just kiddding, good luck, Richard
Edit: Sorry, I've been running Mint Xfce on my old IBM A31p since 5, and still on 6. Have KDE, Xfce, and Gnome sessions available, compiz if I want to impress my colleagues, AND dual boot to xppro! All of my keys worked out-of-the-box since day one, and the old FireGL graphics works great, even on the 'Live' Mint 7. I like the quick boot of 7, but 'it ain't broke!', why mess with a good thing?
