Did I accidentally damage my laptop by overheating it?

I accidentally left my laptop on and put it in its case in my backpack for over an hour. When I took it out, it was super hot to the touch—like I actually burned my fingers! There was a weird white screen when I first opened it, but I shut it down and restarted, and it seems to be working fine now. I'm worried I might have damaged the battery or something else, especially since I've noticed my charger gets really hot sometimes. Is there any chance I've caused irreversible damage to my Lenovo Yoga Slim 7?

Don't stress too much! Your laptop probably just overheated because it was closed in the case without ventilation. The weird white screen might just be a software glitch. Newer laptops have safety features to prevent damage from overheating, so as long as it's working fine now, you should be okay! Oh, and it’s normal for chargers to get hot, especially if they're robust.

That overheating is definitely not great, but most laptops can survive a good amount of heat without major issues. It’s always best to back up your important files, just in case. Moving forward, make sure to shut it down properly or let it cool before putting it in your bag. Also, chargers can get hot; just ensure it’s not burning to the touch!

If your laptop is running fine now, you likely don’t have anything to worry about. Just keep an eye on it. The overheating isn't ideal, but laptops are designed to handle a bit of heat and usually won’t get permanently damaged just from being in a bag for a short time.

Your laptop likely has thermal protection, so if it felt really hot but it's working fine now, you’re probably in the clear. Just be careful next time and try to let it cool down first before putting it into a case. If the charger is overly hot to touch, you might want to place it where it can get air circulation more easily.
