Motherboard could of gone bad. I have also seen bad memory cause this issue. Another possibility is the power connector on the motherboard came un soldered.
Try reseating the memory and see if that helps. Otherwise, a repair is going to be expensive.
Tried reseating the memory, hasn't worked. Still dead. The power button I have replaced before which goes to connect to the mobo via a ribbon cable, but this time I know it isn't that. Not sure if the power connector is different from this, though.

Just make sure you unplug the power adapter with the battery out and then hit the power button a few times. Then reconnect the power adapter and try it.
Yup, that's the first thing I did but it wasn't having any of it.

If your Dell power brick has an LED:
- Unplug it from the mains and the laptop
- Wait for the LED to go out
- Plug the brick back into the mains
- Keep an eye on the LED -> plug it into the laptop
If the LED goes out straight away, you have a short of some kind or a loose PSU connector and will need to get it repaired.
If the LED stays on, but refuses to power on when you press the power button, it might be in "fail safe" mode believing there to be a power issue and has switched itself off to protect itself. Leave it unplugged without the battery and press power to use up any residual charge. Give this a few mins then try with just the PSU plugged in.
Either way, either leave a faulty battery disconnected or replace it as it's dangerous and could cause some serious damage.
The brick that came with the laptop didn't have a brick but I do have another one lying around from another laptop with an LED, but this stayed on when I plugged it in. I've done what you have suggested but still won't respond to anything

This is what my initial thought was. Try jiggling or pushing down the power connector when connected to the laptop and see if it will power up.
I've seen it happen a couple times and was able to solder it back on, but it's not the easiest task in the world.
Yeah, it doesn't want to turn on.
