I can't help you with the KLaptop as I've notice the same is happening here - no battery mode.
I've unplugged the back now and am restarting .. so let's see ...
ok XF86Config-4 is a configurationg file that can be edited manually
it contains information about your video setting, mouse configuration, resolution and graphics driver.
vi /etc/X11/XF86Config-4 (just for a colourful preview)
use pgup and pgdown to find Section "InputDevice"
for example
Section "InputDevice"
Identifier "Mouse1"
Driver "mouse"
Option "Device" "/dev/input/mice" ####
Option "Protocol" "ExplorerPS/2"
Option "ZAxisMapping" "4 5" ####
EndSection
Most likely you will have to change the lines #### to make your mouse work
Now log in as root
and type something like kedit /etc/X11/XF86Config-4 (if you have that installed)
and change those lines with whatever is ideal for your mouse (myself like you, would have to find out)
The last item is a tricky one - because I've always stayed well clear of wireless internet
Try MandrakeControl Center in the Menu:
System->Configuration->Configure Your Computer
A window should appear with icons
Click Network and Internet
And you are presented with more icons
Now its a question of experimenting a few of those:
You could start with "New Connection" and go the Wireless Connection route again.

Oh by the way, KLaptop seems buggy - it still shows no battery.
Maybe someone should inform their development team.
