Lenovo G500 For Spares Core i3 3110M 2.4GHz 4 Cores Intel HD Graphics 4000

The motherboard is booting up and loads windows without any issues. One problem we found, is that it won't take any random WiFi network card, prompting a message while booting up, stating that the network card is unauthorised and that we need to remove it and restart. We haven't looked into this issue any further as the case of the laptop is damaged, the screen is not secured in place anymore, the bottom cover has both holding pegs broken and the top cover has a crack. While having the unit on, we have spotted a mark towards the top left of the screen, where we assume there may be some dead pixels (sorry, we forgot to take a picture).
