Dell Latitude 5480 not giving video and a HP laptop needing a battery and has some software issue

The Latitude 5480 just powers on and nothing else. The HP I'm told the battery doesn't last long and there is some kind of blue screens that come up.

You can purchase the tools I use in my videos using the Amazon links below.

This one I keep in my car for mobile work. It's very good and much cheaper that the iFixit kit

This is the one I have. It has the same 64bit set along with some other useful tools and a carrying case.
