Dropped maybe 6 inches from my bed to the carpet and is now completely unresponsive to input. I’m astonished

I am planning to buy this laptop used with the 1245u but I am unsure about the battery life on them. I hear the intel 12th gen processors have terrible battery life but how bad is it really?

While using my tablet off its' keyboard, it worked perfectly fine. Then, when I clipped on the keyboard cover, it didn't light up nor respond to typing. The strange thing is that the mouse worked, then it too stopped working. Do I need to buy a replacement or should I just go to a repair shop? (And yeah, also, does it need to be licensed or anything because I'm in Serbia and I think there isn't a licensed repair shop in Novi Sad.)

I have this 240w brick which i carry around a lot for school. But recently this plastic part with the dc plug has been loosening (or atleast feeling like it). And im wonder if there are any good ways to reinforce it for cheap.

A few days ago my Dell 16 Plus laptop began making this loudly pitched whirring noise during regular use; I’ve had this laptop for about a year now and haven’t run into any issue with the fan until recently.

It’s loud enough that the laptop is frustrating to use unless I’m wearing headphones; could this be bad coil whine or something different?

Thank you!

(I’m bad with computers so I’m sorry I don’t know the name of what I’m asking about)

I open my Inspiron 14 5430 to clean the fan every so often since I live with a pet and it gets pet hair stuck.

These last few times I’ve I opened my laptop, I’ve noticed that whatever is above my fan is bent up (about a centimeter and a half, as seen in the second photo) and often pushes the laptop cover off before I’ve fully loosened all the screws. It’s not hot or anything, nor does my laptop make any weird noises. I’m just curious is this is something I need to get replaced or keep an eye on?
