I have a Lenovo IdeaPad Slim 3 that I've had for about a year, but I haven't been great at taking care of the battery. It died pretty quickly and even started to swell, so I had it removed. I've been hearing mixed opinions about running my laptop without a battery, specifically that it might degrade over time. I always thought it could function like a desktop as long as it's plugged in. I'm concerned since I use it frequently—will it really get damaged if I keep it running without a battery?

You shouldn't have any issues using it without a battery. A lot of people do this. Just keep in mind that some brands, like Dell, might require a battery for updates or specific features, but for daily tasks, you're good to go!
Some laptops may have performance issues or won’t even boot without a battery, but if your Lenovo is working fine, it should be alright. Just a heads-up—some HP models might throttle a bit without a battery. It's always good to check the specifics for your model!
Running a laptop without a battery is actually pretty common; it’s like using a desktop without a UPS. It should work just fine as long as you don’t have power outages. So, no worries there!
It’s totally fine to run it without a battery. Just to be safe, I’d recommend getting a small UPS power bar to handle any sudden power fluctuations or accidental cord pulls. Would that work for you?
Would a surge protector do the job too, or is a UPS really necessary?
Using a bad battery can be troublesome, especially if it keeps charging and discharging. But since you’ve already removed the faulty one, you’re in the clear. Your friends probably just don’t get how these systems work!

I agree! I always use a UPS for my setup, but it’s great that laptops can run just like that if needed.
