It is not possible to retrieve a forgotten passcode from an iPad2, and coupled with a new laptop, your only option is to restore it to a factory fresh state on IOS 6.0.1.
In order to do this, you are going to have to use a special mode, known as DFU mode. We have a guide here, to help you get into DFU mode -

Once you are in DFU mode (the screen will remain black, but iTunes on your PC will recognise the device), you will then be able to press the "Restore" button and iTunes will put IOS 6.0.1 on there. It will completely wipe all the information from your device, but since you have forgotten the passcode, you have no option but to do that
Good luck.
