Is it possible to get a new battery for the laptop mentioned above.

I can get about 2 hours on a single charge, but when I am out in the
field with all of the USB ports used, it doesn't last very long.
(Think South Africa at the moment:-( )

Also, does this laptop suffer from an inherantly bad display, only
capable of 800 x 600. Think grainy and lag.

Also, where can I get a manual for it?

Thanks
