Laptop or desktop computers and any components within.
Matthew has an Asus laptop and it restarts from time to time. Leo says that it's crashing and shutting down to protect the hardware from damage. Leo suspects that it's overheating. Matthew can remove the outer case and clean it out with a vaccum cleaner or blower. A fan may also have stopped working, especially one for the CPU. If the thermal paste that attaches the fan to the CPU has dried out, that could be causing overheating issues as well. A flakey power supply is also a possible culprit. Leo suggests finding an independent computer expert that can fix it.
Chip wants to know if anyone really needs to attend CES anymore since everything is available online. Leo says not really. He sends people to cover it. It's a great experience to go at least once. It's out of control, and there's so much to see. But Chip could pretty much see everything virtually now and doesn't need to feel the pressure to attend every single year.
Bob wants to use his Canon Rebel T3i as a webcam. Leo says he would need HDMI passthru. He'll need a miniHDMI to HDMI cable, then he can connect it to his TV. But if his computer doesn't have HDMI, then he'll also need a video adapter. But for all of the effort required, he should probably just get a good HD Webcam. Leo likes the Logitech C920. It'll connect via USB and will work great.
The big story at CES 2015 was in drones, virtual reality headsets, and 4K TVs. The big news with the 4K TVs is that we may finally have a standard for the ultra high definition sets, as a UHD alliance has been formed and UHD Blu-ray players finally had a standard adopted. But they won't be available until the fall. The standard defines the dynamic range and color gamut, as well as the compression algorithm, which is HEVC/H.265.
Dickie D is back from CES in Vegas and there's one gadget he thought was perfect for the tech guy. It's called the Zolt Laptop Charger Plus, and it's the world's smallest and lightest laptop charger that can charge just about any laptop out there. The Zolt has 3 USB ports built-in that allow it to charge multiple gadgets at the same time.
Tom saw a new box from Bitdefender at CES that promises to be in between the internet and the computer and cleanses all traffic. The box connects to the router and it will prevent malware from getting through. They plan to ship it for $200. Leo says the premise of this is good, but may not necessarily be better than a software antivirus because if software doesn't know about a virus, neither will the physical box. We can't even be sure it will ship at all at this point either.
In addition to some interesting new products, like self driving cars and drones, CES was what Leo called "Groundhog Day." There was about 10% new stuff, another 20% crazy stuff that will never see the light of day, and the rest we've all seen before.
Jonathan has Verizon FIOS with 75 Mbps up and down. Leo says that's nice! He has great signal on one side of the house, but it's terrible on the other side. How can he extend the Wi-Fi? Leo says he has to use Verizon's FIOS modem and router, but he doesn't have to use it for Wi-Fi. He can get a better Wi-Fi access point like an Apple Airport Extreme. Then put that in bridge mode so it'll pass the signal along to the rest of the house. If he needs more, then he can add a few $99 Airport Express's to act as a repeater. Leo has three of them.
Alan just got a 15" MacBook Pro, but he considers himself a geek and is wondering if this was really a good purchase. Should he switch? Leo says that OS X is far more secure, having been based on a pure UNIX system called BSD. It's important to note that he can also run Windows on it through Boot Camp. So when he boots up, he can choose Windows or OS X.
Amy has several chargers and they all charge at different speeds. Can she run a speed test to see how long it takes to charge them? Leo says she can monitor power usage with the P3 P4400 Kill A Watt Electricity Usage Monitor. This plugs into the wall, then she can plug a charger into that. There's also this USB in-line voltage and current meter from ADAFruit.
