Hi @winson2769

What is the model number of the Lenovo tablet?

It should be Lenovo tab 7

Can't you just plug an adapter into the tablet's micro USB port and power it that way? You only said that the battery was damaged, not the USB port.

Unless the USB port is loose or physically damaged, this would indicate that there are more problems on the motherboard as the tablet should recognize that power is connected to it.

I can't find the schematics for the motherboard for the tablet, so I don't know where to connect the cables.

What is do know is that you don't want to connect them so that they're bypassing the battery management circuit in the tablet, as this may damage the board even more.

Sorry I can't help you.
