Dell latitude won't turn on
I was using my laptop and randomly the computer froze. The mouse wouldn’t work etc. after 15 minutes to hard shut down the computer. I now can’t get it to boot back up. I can hear the fan running after turning it on and the light indicating the power cord is plugged in is on. The screen is black but all leds are white and shown to be working when powering up. Cannot get pass the black screen. Even including the hard reset.

I cannot tell from your earlier post whether the system does boot and load an OS, or not -- it sounded like it did not either way. If the system will power up to a setup screen without the battery but not with it, the battery is the likely cause. If it won't, the mainboard is the likely cause.
Whether or not it'll load an OS depends on whether you have one installed (or in fact whether or not the system has a hard drive or SSD in it).

Unplug the system, remove the base cover and disconnect the battery from the mainboard. Hold the power button for 30 sec. Remove and reinstall the memory modules.
Reassemble and see if the system will power up.

@ejn63 Hey so, number 1. It didn't work, 2. I tried opening the laptop using the charger while it had no battery, obviously the system didn't boot but it did "power on", 3. With the battery reinstalled it did nothing, no screen regular leds opening including the capslock and what not but no screen boot. Help?

The path forward almost certainly requires a replacement system board; your call as to whether that's worth the cost. It'll depend on what the system is and on how old it is -- if it's more than 5 years old, it'll probably make more economic sense to replace the system than the mainboard.

@ejn63 For context I bought it off ebay where they said the battery held a charge but "the remaining life cannot be predicted or guaranteed" I really enjoy this laptop and hope it might be the battery that needs replacement.

@ejn63 without the battery when I tried to power it on with the charger, it did work as in it could still do automated processes. (E.g Power On AC, indicator lights etc.)
