What would be the best way to do a DIY repair a crack that's developing on the lid of my Dell laptop? I don't really have the cash to get it fixed professionally and the warranty has expired, so I was just wondering whether there was a sealant or glue that would be suitable for stopping the crack from spreading and to close it up, and wouldn't damage the laptop? The crack is occurring around one of the hinges on the back cover. Thanks in advance if you have any solutions.
