Says that windows failed to start, freezes when loading drivers. Also says clock isnt set right and anything i try plugging in fails to load. Ive updated bios to ?29? Still same thing. Diagnostics says hdd is bad but i have a ssd in there that im told should work
Sounds like the CMOS battery is dead.
This page refers to your laptop specifically: Dell Latitude E7240 Ultrabook CMOS Replacement
But this one is far better and should give you what you need: Dell Latitude 7490 CMOS Battery Replacement

It also gives me a clock issue, it's because my CMOS battery is dead and I haven't replaced it yet. Keep pressing f12 to enter into "one time boot menu" and select what you want to boot off
