Running laptop without a battery
Discussion
My partner's Dell Latitude laptop won't boot up.
It starts, says "Critical Battery Error" and then shuts down, despite being plugged into the mains via the Dell charging cable.
She only ever uses it at home, so can we remove the battery completely and just run it on mains power? Or does the laptop need to "see" the battery is there and working in order to boot?

I've got a Dell Latitude laptop (2017) in a similar condition. Battery is totally stuffed but it should still boot up with the charging cable plugged in. The battery can be replaced but if it isn't easily removable some disassembly will be required. There will be YouTube videos on this depending on your particular model / year.
(Whilst on AC Power of course)
When it POSTs (Shows the screen that says "Critical Battery Error", have a look for anything like
F10 / DEL | SETUP / BIOS / SETTINGS
Or similar. Usually you can get there by just hammering Delete / F10 / F12 whilst the laptop is booting up; depends on the manufacturer and model.
Once you're into the setup menu, dive around the options - There is one in dell that allows you to control warnings for peripheral / battery errors - You can choose to ignore, warn and wait, warn and shutdown etc.
Swap that to ignore and it should boot perfectly fine as long as you have AC power.

is the power supply working? IF it won't run(at all) with the battery removed and the power supply plugged in then that is your problem.It starts, says "Critical Battery Error" and then shuts down, despite being plugged into the mains via the Dell charging cable.

Depends on the laptop how well it'll work without the battery.
One on my stack of chunky gaming ones managed to kill the battery by running flat and staying that way, laptop runs OK but will randomly shut down under load as the 250W power brick isn't up to running the GPU + CPU at high load and without the battery to make up the difference it can't cope.
