Episode 1284 (2:09:29)

Larry from Black Forest, CO

Larry is a firefighter and they use a mobile computer GPS utility running Windows. But there's some Panasonic Toughbook laptops that he can't get to work. Leo says that there's a video on how to install it here (YouTube)

The chatroom suggests cloning the hard drives on the ones that do work and then manually inputting the proper activation code. If it works, then he'll know it's a software issue. If it doesn't, then it's a hardware issue.
