Is it harmful to use a lower wattage charger with my laptop?

In my experience, if you use a charger with lower wattage, the laptop may run hotter than normal. I once used a 90W charger for a laptop that required 120W and faced some minor crashes during heavy use. While it didn't damage the laptop itself, it did limit its performance significantly. If you didn’t notice any physical issues while using the 65W adapter, your laptop should be okay. Just make sure to use the right charger moving forward!

Most laptops with high power needs will alert you if you try to charge them with a lower watt adapter. Some brands like Lenovo do this. They might still charge at a slower rate, but for gaming or heavy tasks, you’ll likely see performance drop since the battery might drain faster than it charges.

Using a lower watt charger can impact performance but generally shouldn't cause lasting damage. Your laptop will just throttle itself to match the lower power input. If you switch back to a higher wattage charger, it’ll only draw what it needs. Just keep an eye on things, and hopefully, your laptop will be back to normal!

Your laptop was definitely power-starved with the 65W charger. It may charge the battery but it's likely capped performance-wise. You're good as long as everything seems normal with your original charger. If you're able to, check if your laptop settings allow changing to a lower power consumption mode to help manage things better.

Using a lower wattage charger usually isn't a big deal for newer laptops. You just won't get fast charging. However, for intensive tasks like gaming, your laptop might actually drain the battery while plugged in. It's more about performance limitations than damaging your laptop directly.
