You may have a pile of scrap depending on how deep the lock is. If it is Windows you can easily get it unlocked at a PC shop. (I am not going to tell you how to on an open forum.)
If it is a hardware lock then you still may be able to fix it. Go to www.lenovo.com and download the Hardware Maintenance Manual for the model that you have.
However you may find that the lock is so deep the fix is to replace the motherboard, which is not an economic fix. This is done deliberately by manufacturers to ensure that stolen laptops have no value and thus deter their theft.
