Laptop or desktop computers and any components within.
Daniel wants to know about wireless home security cameras. He's looking for a good 5GHz camera that can be battery powered. Leo says that battery powered cameras aren't always on -- they use motion detection.
NetGear's VueZone is a good brand. 5GHz, on the other hand, isn't as good as 2.4GHz, even though it's less congested. The higher you go in frequency, the more likely the signal will bounce around and get interference. The batteries do last for a year in those cameras, though.
AJ opened up a laptop he hadn't used in awhile and all of his music and pictures were corrupted. A popup actually said the disk couldn't be read, and must be formatted. He tried to recover it. Why did it become corrupt? Leo says that hard drives die, and that's why you need a 3-2-1 backup strategy. 3 copies, on two different formats, with one off site.
Dennis was into computer flight simulators, and he's wondering if virtual reality will be the next great thing in flight sims. Leo says virtual reality will be more immersive and give him a better experience of what it's like to fly. But to use a VR headset like the Oculus, he'd also have to upgrade his computer. So he's talking about $2200 to get the experience he wants. Leo says that VR is an amazing experience. Although it's in its early days, it will get better.
Tarino is in the market for a new computer and wants to know what Leo thinks about the HP Envy All-in-One PC with 34" Curved screen. Leo says it's gorgeous. At $1500, it seems high, but the screen alone is $800. And it's extremely wide. So Leo says it looks like a good deal. It's not the fastest computer on the market, but it's a neat screen.
Terri is going to a conference and wants to bring a tablet to replace her laptop. How can she replace it without paying for an iPad Pro? Leo says that Samsung makes a tablet, the 8" or a 9.7" Galaxy Tab S2, for around $400. And she can use a third party bluetooth keyboard so she doesn't have to pay a lot. Terri can also sync it with her Note IV.
A student researcher has taken a jell and coated the inside of a lithium ion battery with it, that will enable it to cycle hundreds of thousands of times. The result is that if commercialized, there could be batteries that could last forever. It doesn't improve capacity, but it does eliminate the wearing out issue.
Tryell says that Apple has done an outstanding job with accessibility while Google and Microsoft have a lot of work to do. Leo says that Apple is the gold standard on accessibility. The screen reader is great, and it doesn't cost any extra either. So many of those tools are so expensive.
Bernie has a dual boot system running Windows and Linux. He wants to know if he can reformat his hard drive to make more room for Windows since he doesn't want to use Linux anymore. Leo says he won't be reformatting, he'll be repartitioning. That means he'll adjust the section for Windows to make it larger. Windows installer has a partition utility built in called FDisk. He should look into options, find the Linux partition, and delete it. Then he can make one large primary partition on the Windows drive. He can then format the partition to NTFS.
JC is a SysAdmin and he's looking for an imaging program that can help him manage 30 company computers. Leo says that there's great free imaging programs for that including:
The advantage of this is that he can create a drive. Then he can simply plug in the drive, boot to it and then clone it to the main computer. And it doesn't have to deal with Windows. It just restores the sectors. It can even support Windows 95 and FAT 12 all the way up to Windows 10.
Other options include:
