Due to sheer lazyness (please, I beg of you—do.not. be like me!), I didn't bother to get my MacBook charger checked out for months. It's been wonky since late September/early October. So most of my internet-surfing since then has occurred on my phone or my mom's iPad. Yesterday, I was like, "Fuck it, I have to go to the Apple store and get this figured out."
And I did, and I got a new charger for free, even though I'm out of warranty by now! So happy that I can finally type on this laptop again, because typing on a keyboard is SO. MUCH. EASIER. than typing long comments/posts/emails on a phone or iPad.
Also, like I said: don't be incredibly lazy like I am. This was something that could've been resolved 3 months ago, HAH.
