I lost my driver casset for r lenovo b460... how am i get......

hold down your function key and press up or down on your keyboard, according to the manual for your laptop that's how you change the brightness on your laptop display.

Unplug the power cord
Take out the battery
Hold Power button for 30 sec
Tap Power button 30 times
Put battery back in
Plug power cord back in
Press power button to turn on.

Ok, I stand corrected. I never knew this technology existed. I looked at your manual and it indeed shows a sim card slot. The manual also gives instructions on how to insert it and what you have to do to make it work.

Below is a link to your manual.

If your laptop has a slot for the simcard, all you have to do is just insert it and wait until the system recognized the hardware. Hope it helps thanks.
