My mom bought a used laptop from a thrift store/consignment shop recently and went to start the laptop up and it's nothing but the black screen with a blue box and NOTHING we've tried has worked for her! I'm wanting to help her so hopefully she didn't waste her money on this laptop. We've tried the f buttons it doesn't bring anything up, the enter key does nothing and nor has removing the battery attempt. CAN ANYONE HELP ME ASAP PLEASE???
