Cotton has a 2013 MacBook Pro, and recently had to buy a battery from MacSales.com because it began to swell. He also replaced the SSD. He had to remove the battery with acetone because it was glued in. But after installing it, the laptop was dead. Leo says to head over to iFixIt.com and check out their instructions on replacing the battery in his laptop. He may have missed a step. But it's also very possible that Cotton may have shorted out something like a fuse.
IFixit tears down mobile phones to see if they can be repaired and they found that the iPhone has a gigabit wireless antenna, and the IP68 rating is pretty legit. The taptic engine is better than any device out there. One thing that Apple didn't tell us, is that the Camera bump is even bigger than before. The cameras are bigger, and it likely means you'll have to get a new case, rather then try and use the older iPhone X case. How big are the batteries?
Brad and his wife both have iPhones and they shut down with 15% left. What gives? Leo says it's a software thing. In essence, the phone is making a guess and as a phone gets older, it has less capacity. So that estimate can get more inaccurate the older the phone gets. Batteries can be recharged about 500 times, and as it gets closer to that number, it gets more inaccurate. Brad doesn't want to buy a new phone, though, and Leo says he doesn't have to. He can go into Apple and request they replace the battery. It's about $100. Can he do it himself? Leo says maybe.
Luis has a second generation Mac Mini and the hard drive crashed. The repair techs want to charge him $350 to replace it. Leo says that's nuts, and he can do it it himself. Macs require special tools to open it up, though, because they use friction to keep things together.
Eric has a first generation iPad that won't charge. Leo says that the original iPad needed a 10 watt charger and if he's using the smaller cube, that may be the problem. He should try a USB charger that's 5 volts and 2 amps. That should do it. If not, it's likely that the battery has reached the end of it's life and needs to be replaced. Apple will replace it for about $90, but if he's a hardy type, iFixit has directions and videos on how to do it.

Mark got an iPhone 5s from a friend that had a "dog bite" in it. It will work connect via 4G, but not via 2.4GHz Wi-Fi (5 Ghz is fine). Is it worth fixing? He's tried DFU'ing it. Should he try iFixIt? Leo says he can look on iFixIt and get a teardown of the phone to see if the parts that don't work will be replaceable. Some aren't. Leo says it may be the antenna that is damaged. If he can replace the antenna or the Wi-Fi radio, then he should be OK. If it's soldered onto the circuit board, then he's out of luck.
