I ended up ripping a component on the motherboard on my notebook

By accident when removing the battery, I accidentally ended up tearing off a very small black piece in the shape of a rectangle that I can't identify or say what it is, but where it was is written "PD3"

My notebook model is dell g15 5515 Ryzen edition

I would like to ask you guys if it is too risky to continue using your notebook like this
 
It might not even power on, as that is some kind of Voltage regulator or similar, so yes, it would be risky, as you could end up frying some other component(s) when you power on the laptop.
 
Looks like a small transistor. Replace/resolder it/have it resoldered; do not turn the unit ON without it.
 
Nah, that should be an LDO Voltage regulator or something like that, only three or four pins by the looks of it.

Hello, thank you very much for your time and help, I ended up turning it on before reading your messages to see if it works and everything is normal, but as you are much more experienced than me, I'm going to follow your advice and keep it turned off, I still have the part and I'm going to look for a specialized place to put it back in place

The thing is, it might not happen straight away, but that most likely drops the Voltage to some component from say 3.3 V to 1.5 or 1.2 V or something like that, so give a little bit of time and something is likely to die, which will be more expensive to repair, as you migth have to change the entire motherboard at that point.

I understand, unfortunately I didn't have this knowledge at the time, I hope it continues to work after the repair.
I'll leave it off until I can take it to the repair center nearby.
I still have the part , which is a diode SOT(3)23.

You're lucky then, as it's a fairly common part and the repair should ought to have spares.
 
An update on the situation, I managed to find out which part it is exactly , is the BAV99W_SC70-3 chip which is a High-speed switching diode, it looks to be part of the power delivery circuits, either I will have issues charging without it or your battery may overcharge and become damaged.

I removed the battery to be safe.
