If you really don't have the skills to repair modern electronics, please don't try to open the tablet. You won't be able to open it in the first plase, without damaging the tablet.

To connect up a tablet with a laptop you need to connect them with a USB cable.

On plugging in the cable with the tablet powered up, you should see two things.

1. A question on the tablet as to whether you want to use memory disc mode or diagnostic(ADB) mode. Choose Memory disc mode.

2. You should see on the PC laptop it recognise that an external device is connected, it may recognise it as a phone or a memory drive.

If neither of these things is happening it is probably the cable at fault.

The tablet should then start providing the pc laptop with the drivers it requires to be recognised. If this does not happen, then the fault is with the tablet and you have to consult your supplier.

You should end up with at least one memory drive which you can browse through with the PC's file manager. The data will be on the tablet.
