This might be another good reason to install Ubuntu 9.04:
I looked at the battery, then called up the Dell recall list. Sure enough – that battery was listed. Interestingly enough, I’ve had this D600 for a while now and there has been no problems up until a week ago when the battery wouldn’t take a charge. Since I usually have this machine plugged in, I never thought twice about it.
The Ubuntu 9.04 was pretty easy to install on the Dell. I still need to fix the wireless, however all other items seem to function normally.
I will get the battery in the mail soon, along with that DVD+-RW Lightscribe and extra memory I just ordered for it. RAWK!
You can thank Red Hat for working on this. Richard Hughes who maintains gnome-power-manager works for Red Hat.
That could be the best ever reason to install Ubuntu! Do please let us know what package determined this and told you :-)
