Ugh. I downloaded and tested the ISOs for Maverick and Lucid (10.04.4 version) and was met with the same results I had with Natty (also had to use nomodeset to boot). Neither recognized the battery (including a boot to Lucid on battery only). I know for certain when I had Lucid, the battery was recognized and charge status was reported. Note: battery was recognized on the Oneiric ISO but failed to update status (like Precise).
There is no acpi on any of the ISOs (maybe affected battery recognition?) and I know I've always had to make sure the nvidia drivers are current on any distro (otherwise get xorg errors on boot) and probably why I have to use the nomodeset option on the ISO boot. However, I doubt the nvidia card/driver would affect the battery recognition on the boots. Maybe it is some hardware issue with the battery but when I use the boot to Win7 (32 bit), Windows does report and update the battery's charge status. While trying to search for some more answers, I came across this: http://askubuntu.com/questions/35102/battery-not-recognized-on-my-laptop-and-it-recognizes-my-laptop-as-a-desktop The last comment notes: "If you run windows ever, Windows can change your battery settings (somehow) and make it unreadable by some linux distros." As the machine is a dual Ubuntu/Win7 boot option, I wondered if Win7 screwed something up, so I booted to Win7 and put the power settings to defaults. It still didn't fix the problem. I wonder if there is a hardware issue that coincided with the update to Precise or if a Win7 update related to power management messed something up (also coinciding with the upgrade to Precies). Let me know what else I can troubleshoot to isolate the problem.

I do not get warnings when the battery is low (laptop promptly shuts down). 2. Battery power level is not updated. using acpi the battery power shows the same level present when the laptop booted - it never updates (if booted at 98% it will show 98% until rebooted). 3. Battery status (on power vs on battery) functions sporadically. Often after an update the status will work for several boots but then stops working (icon only shows status when booted - ie, if cord plugged in, the status will not change to "on battery" if unplugged; it still shows that the laptop is plugged in. 4. In power settings, "Show battery status in the menu bar" is blank. I can select options from the dropdown menu but they are not retained (when I close and reopen the settings it is blank again). 5. Went to gconf-editor apps > gnome-power-manager and noticed that there is no "notify" folder/keys. 6. Noticed that there is no gnome-power-manager.desktop in /etc/xdg/autostart/ (wanted to add it to autostart to see if that would help). I have tried using synaptic to reinstall gnome-power- manager but it didn't help. Currently, my status (icon changes to battery/plugged in) and acpi output is: Battery 0: Unknown, 98% (plugged in) Battery 0: Discharging, 72%, 00:59:42 remaining (on battery) I have also added my dmesg outputs for on battery and on power (attached). The laptop is an MSI-171F. I have tried blacklisting msi-wmi in modprobe.d/blacklist.conf (didn't help). Also noticed that etc/acpi has sevearl asus*.sh files (touchpad, keyboard backlight) in the folder (could that be the problem) Note: I currently have Jupiter enabled but have disabled/uninstalled it before and it didn't seem to affect the behavior. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.25.
