Working mac os

Hi all

I am new to mac and have managed to install , this seems to be working well
System Version: Mac OS X 10.5.5 (9F33)
Kernel Version: Darwin 9.5.0
Boot Volume: MAC OS
Boot Mode: Normal
Computer Name: roger s’s AOA150
User Name: roger s (rogers)
Time since boot: 50 minutes

just a couple of questions
1 i have and icon in the task bar Power card ?? What is that it says Power Card Off, unknown vendor this is repeated four times.
2. i have managed to install a usb Belkin wirless card type G Plus MiMo [ a bit large almost the size of the acerone] can anay one sugges a smaller dongle that will work.

I will test as see if it seems ok one thing that intrests me is the battery life as it rports when fully chared 1hr 51 mins.
not sure how accurate this is.

Finally I would like to thank all the people that have made this possiable, I really wantred to try mac os and no i have the
chance with out the expense.

Thank you all

Excell
