Tom got a notice from Microsoft to update Windows 10, but now it won't recognize his keyboard, so he can't log in. Leo says that Tom can eliminate the keyboard as the problem by trying it with another computer. But likely, the update deleted or corrupted the USB drivers. Log into safe mode and see if it works. If you can at least get into the BIOS setup, then you know it isn't the keyboard.
Elizabeth has an HP OfficeJet Pro 8715 printer. But her menus say 8710 on the screen. Leo says the printer probably uses the same drivers because it's part fo the 8710 line. She is also being told she needs new ink cartridges and she replaced them, but now it won't print anything. Leo says to look in the setup menu to see what the error message is. It may also be security software from a third party or counterfeit cartridges. HP won't allow them. That could be the issue.
She may also need to update the drivers.
Mike recently upgraded his old Acers to Windows 10. But after running the Microsoft System File Checker, he's having issues accessing features in his account, particularly settings. So he did a repair reinstall. Now he can't get back online to the Internet.
Leo says to go into the device manager (Windows + X) and see if any devices are missing or have a red "x" or "!" in the corner. It could be a driver issue. Also, look in the settings to see if sleep is enabled and turn it off.
But your WiFi card may not be supported anymore. Luckily, they're cheap.
Donald is dealing with a horizontal crop issue on his TV. He tried to change the aspect ratio, but all he seems to be able to do is zoom it in, which doesn't help. Leo says that there could be a fit screen option that's been enabled. It could be called Zoom or Stretch. Underscan may also be the option. Try looking for that and disable it. Also, look for 1-for-1 / 1:1.or 16:9. Some movies may end up with letterboxing however. If it does, then zooming it will distort the image and crop off the image like that. So check your aspect ratio settings.
Nus is having issues with Google and his Duo app. Leo says that click on the three dots in the right-hand corner and it will show what account users are signed in with. It's possible that Nus signed out or removed his account accidentally. Nus says it doesn't remember it and tells him "something went wrong." Leo says that usually means it can't write to it. He recommends uninstalling Duo and reinstalling. Leo also recommends going into the phone app settings and look under the DUO app for clearing storage and cache. That will wipe it clean and start over.
Andy has updated his mom's computer with Windows 10 Home. He's got her Defender AntiVirus all updated. But now, her start menu won't come up and the Windows key doesn't work. Should he look at the registry? Leo says NO! Trust the solutions at Microsoft.com. Leo says that any user who isn't sure what they are doing can mess things up in the course of learning to use their system. The reality is, Windows is too powerful for your mother or someone who isn't a sophisticated user. Leo recommends replacing that Windows 10 system with a Chromebook.
Bob recently bought an eero mesh router. It worked fine for two weeks and then he started experiencing dropouts, and he can't get support. Leo says that support is terrible these days because of limitations due to CoVid. Another thing to look at is your ISP and cable modem. Security software could also be an issue and can inhibit your internet access.
Ken is on a limited budget and he installed a new OS on his old laptop, but he can't get online now. Leo says that it can be several things. It can be the ISP. It could be the wires coming into your home. It could be a configuration issue. One easy test is to see if your internet is working elsewhere. If your phone has WiFi, then you're in good shape. That would point to an issue with Ken's laptop. Try connecting the computer to your router with an ethernet cable. If that works, then the issue points to the WiFi radio itself.
Dan built a computer using an AMD Ryzen processor. He's been watching YouTube videos a lot on doing it and is ready to give it a go. Leo says there's a lot of great information on YouTube, but sometimes they can get it wrong, so keep that in mind. It worked for five days and then just stopped working. Leo says that building a computer is a great project, but if something like that goes wrong, you are your own support. There's no one really to call, as everyone will blame the other guy for the problem. So you end up having to go one by one to determine what goes wrong.
