Laptop or desktop computers and any components within.
Scott wants to know if he can take the hard drive out of an old computer and then put it into a new one. Leo says yes, but he should only use it as a data drive. He could probably put it in an external USB enclosure so he can plug it in when he needs to. He could install it as a secondary hard drive as well. If he wants to use software from that hard drive, that's a lot more problematic due to registry issues. He may be able to dual boot from the older driver, but the device drivers won't work. So he'll have to work around that and use a boot manager.
Al has an old HP laptop that he got from a friend. It's a little old for what he wants to do with it, so what computer can he replace it with? Leo says to download Ubuntu and install it on that old computer. It's Linux, which means it's free and secure. It's designed to run on older systems as well. It'll breathe new life into that old laptop.
David wants to be able to control his lights with his mobile phone. Leo says he can with so called "smart lightbulbs" that are part of the Internet of Things. But because they connect to his network, they have a huge vulnerability that allows hackers to get into his network through the light bulb.
David loves his Bose Quiet Comfort headphones. Can he get a Bluetooth adapter for it? Leo says there are Bluetooth adapters, but it may not sound as good as he would want it to. There is a new standard coming called APT-X, which is the successor to A2DP and it promises better audio. But both ends have to be APT-X compliant.
Tristen wants to know how to backup his computer so that he has a copy locally. Leo says in the old days, we would divide backup into online, nearline, and offline backups. Online backup would be a hard drive connected to the computer that is synchronizing with data directories. So he'd have a copy on the computer and on the external drive. Nearline backup would be if the drive were put up on a shelf, and disconnected from the computer. Offline backup would be off in the cloud or at a different location entirely. It's best to use all three methods and keep multiple copies.
Martinio can't see his external hard drive on his computer when he boots up. What software can he use to fix it? Leo says first he'll have to be able to see the drive to fix it. If he can't see it, then there's a hardware issue. It's a very expensive proposition to get the data off. DriveSavers will be able to do it, but it's very expensive.
4Moms has a high tech stroller called The Moxie Stroller. It has a power generator in the wheel to charge your mobile device, plus an LCD dashboard that displays speed, distance, temperature and calories burned. It has headlights and tail-lights. The company says it's compatible with their 4Moms self installing car seat we showed last year, and several other models. It's suitable for a child from birth to 55 lb and offers a full coverage canopy with pop out shade and UPF 30 protection.
John wants to know if keeping his Mac on while he's walking around will damage the laptop. Leo says not if he puts it to sleep. It stops reading the drive that way.
What is a hardware password? A hardware or firmware password will keep the computer from starting up in any way other than its designated startup. On the Mac, he'd go into Utilities and set his firmware password. It's very important not to forget it, though.
Jim has an Amazon Echo and wants to know how he can find out if a skill is good or not. Are there reviews anywhere? He also wants to know if there's a way to play audio from YouTube. Leo says he could pair his Echo to his phone and play it that way. It can then work as a Bluetooth device. There may not be a YouTube skill yet, though.
Jerry is getting a new computer and wants to know if he should buy one with an Intel or AMD processor? Leo says that AMD is a bit underpowered and he recommends sticking with the Intel i5. Leo says that for what Jerry does, a Chromebook is a very reliable and low cost alternative. It's the most secure OS out there. Leo recommends the Samsung Chromebook Plus, which goes on sale next month.
