Laptop or desktop computers and any components within.
Joe's wife can't remember the login on her old Windows computer. Leo says that on older Windows Vista computers, security isn't as good as it is now. There used to be a hidden administrator account. Leo recommends trying "administrator" or "admin" with blank password. If that works, she can get in and create a new account to move her stuff over too. There are also programs that she can run that can crack the password. NT Crack is one. But to use it for college?
Stacey has a Dell Inspiron running Windows 7. Can she upgrade it to Windows 10? Leo says yes, and she can do it for free through July 29th. She should wait until she gets the invitation, that means her hardware is compatible. If she missed it, she can download and install the Windows 10 ISO file. Then she can enter in the Windows 7 serial number when she installs it.
Paul has a Ring Doorbell and an Arlo motion detection camera connected to his mobile phone. The problem is that the Ring notification is so brief, he misses it. Can he use a watch to get a better notification? Leo says it's very annoying that you can't customize the Ring notification, especially if more than one person in the office has it. The Ring works with the Apple Watch and it would give him haptic feedback that buzzes his wrist. He'd feel it, but it's also distracting. The Galaxy Gear S2 would also be good if he's on Android.
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.
