My nephew has this laptop and I've been helping him with it but I'm not sure what is going on. The laptop has a variety of reoccurring problems. It has Windows 10 and is the model that has a Core i7-3667U CPU. Sometimes when he wakes the laptop the WiFi stops working. It is as if the Intel Centrino Advanced-N 6235 WiFi card is missing. The network icon on the right side of the task bar doesn't show WiFi as being an option. It shows only the wired networking icon. He's been going in to Device Manager, disabling and re-enabling the WiFi card, and that usually makes the WiFi work again. I used Device Manager and found a WiFi card driver update and installed it. I don't know if that helped or not, yet. He's getting bluescreens about something. Unfortunately every time I go looking for a memory.dmp file or minidumps to analyze there aren't any. Sometimes he refreshes Windows 10 and that seems to set the Windows 10 startup and recovery settings back to default which means no minidumps. I remotely accessed his laptop and set it to save minidumps again. Sometimes if he touches his laptop, or moves it, it switches off. There seems to be no pattern to it. Or, sometimes he can't turn it on. I thought the battery is acting up. We have a replacement battery but I haven't had a chance to put it in. Sometimes he plugs his iPhone in to his laptop and Windows shows a connection is made, then disconnects the iPhone without him unplugging it, then it reconnects, and disconnects, repeatedly. He told me he never has this issue if he plugs his iPhone in to a different computer. Any idea what is going on with this laptop? Is it time to give up on it and get a different laptop?
