Thanks for the tip, merlin1....
Great to have more battery info....
Just tried installing per your instructions....
Was OK up to 'Add to autostarted apps and reboot or from Terminial....'
I opened up 'Startup Programs' and tried adding battwalker there....put 'battwalker' in the first line and 'battwalker.rb' in the second line and closed app...
Then in Terminal I did 'battwalker.rb' and I saw icon appear in taskbar....but in Terminal I didn't get the cursor back...so, after a few minutes I closed Terminal and rebooted....
Now, after reboot, I see a green icon next to Netwalker battery icon. It has 'AC' inside the green square, since I have AC adapter connected...I hover over icon and now I see additional info appear!
FYI, now I don't see Netwalker battery icon...just battwalker icon....
So, all is good, right?
