I borrowed my mom's laptop charger because mine broke today. My laptop displayed the charging icon but the battery didn't actually charge. When I unplugged it, the laptop died immediately. I'm worried—did I damage my laptop? Can I keep using her charger until I get a new one, or is it unsafe?

If your laptop and your mom's charger aren't the same brand, like if yours is a Dell and hers is an HP, it's likely not harmful but it won't charge the battery properly. As long as it powers on, you're okay to use it, but just remember that without the right wattage, the battery won't charge until you get a new one. Don’t stress too much; just be mindful and replace it when you can!
It sounds like you're using a charger with a lower wattage than your laptop needs. Some chargers have the same voltage but different wattages. For instance, if your charger is 65W and your mom's is 45W, it might power on the laptop without charging the battery. You might notice her charger getting a bit warmer as it struggles to keep up with your laptop's needs. It's probably okay to use it for a few days, but make sure to get a charger that matches your laptop's requirements soon!
