Laptop or desktop computers and any components within.
Anna has an old Sony Vaio laptop that won't turn on anymore. Leo says that the battery may have finally died. Her laptop is pretty old and the battery may not be able to keep a charge. She should try taking the battery out and see if the laptop will turn on with the AC adapter. If it can't, she may need to get a new battery for it. They're about $90. That's a lot to spend on an old machine, though.
Victor has an external drive which shows up as a drive, but Windows doesn't read it. Leo says to right click on the start button and select "Disk Management." It may be that the drive isn't formatted or partitioned properly.
Dana is vision impaired and he's excited that Windows new Holographic edition will have a talking installer. Ctrl + Windows + Enter will enable the narrator.
He also has an Acer computer with 500GB hard drive. After ejecting the hard drive, the computer shut down and wouldn't turn back on. Why didn't it work with the AC adapter? Leo says that if he has a bad battery, most laptops won't work even if it is plugged in. It may be part of a power conditioning system.
Karen is a teacher who travels from school to school and wants to know if there's a portable projector? Leo says what she's looking for a pico projector. The wireless connection solution may vary depending on support. They're usually DLNA format. Go to ProjectorCentral.com. Search for pico projectors. Motorola's Moto Z has an add on mod for a projector that attaches to the back of the phone.
David's 2010 MacBook Pro has OS X 10.6.8 and some sites don't support older versions of Safari on Snow Leopard. Leo says that David may need to upgrade his OS. But the question is, can he? The latest update says you can't update to Sierra unless he has 10.7 or later. So he needs Lion. He can't upgrade straight to the latest version. So search the app store for OS X Lion. Here's where - https://itunes.apple.com/us/app/os-x-el-capitan/id1147835434?mt=12.
Matthew used to have a MOTOACTV smart watch and he said it was the greatest smart watch he ever had. Leo says it's pretty large, but looks to have plenty of capabilities. The Nixon Mission Android Wear watch is a pretty good option as well.
Dale is having issues with his old Mac Pro tower. He got a new Ben Q monitor and he has an intermittent problem where the boot up takes a long time before getting to the login page. Leo says that when you power up a computer, it has what's called a Power On Self Test (POST). Leo says it could be a monitor thing. A faulty cable or loose connection could cause it. Sometimes a USB device can hold you up. So try unplugging all your USB devices and see if it makes it faster. If so, then you have a flakey USB cable or device.
Leo spent a couple of hours playing with Zelda on the Nintendo Switch and he was lefty pretty impressed. However, for adult hands, he found the controllers to be a bit small and uncomfortable. Battery life is pretty good at about 3-4 hours of steady play. The big problem right now is that the Switch doesn't have a lot of games at the moment, and of what it does have, most are dumb like Milking Cows. But it was launched with Zelda and Mario is coming. So there's plenty of people to play with until games get ported over.
Rod wants use a display monitor for his store to highlight specials, sales, etc. Leo says that any inexpensive Vizio tv that also has an SD card slot will be a built in solution. That'll be the simplest way. Since it will only be on for 10-12 hours a day, then it won't require a more expensive solution.
