Can I Clean an Old Inkjet Printer?

NX510 

Episode 1630

Don from Culver City, CA

Don has an old Epson NX510 printer that he hasn't used in a long time. The ink cartridges are now really expensive. Is it worth trying to get new cartridges? Leo says that many models replace the print head when users get a new cartridge. So it's worth a try. But it's also worth running the unclogging utility and cleaning the print heads. Users really need to print once a week in order to keep the inkjet healthy. If users rarely print, a laser printer is better.

Episode 1630

Chris from Westlake Villiage, CA

Chris is building his first PC with his dad and wants to know if Leo has any "tips." Leo says that building a PC is a great project that will teach him a lot about how computers work. It's not really hard either, as the pieces will all snap into place. The real work is planning it out, deciding which hardware to use, etc. The first question is... what is the computer going to be used for? Homework? Gaming? Video editing? What's the budget?

Is Pulling the Power Cord on an Active Computer Risky?

 power cord

Episode 1628

Richard from Bell, CA

Richard is wondering if pulling the power cord on a computer (while it is on) hurts the machine. Leo says it is risky because if the computer/hard drive is in the middle of a writing process, pulling the plug could spew data all over the hard drive. Not to mention, physical damage could occur during the interruption as well. It is only okay to pull the cord when the computer is frozen solid and locked up. Unplugging is only a last resort, so always try to hold the power button first before attempting to cut off the power.  

How can I upgrade a netbook to Windows 10?

Windows 10

Episode 1629

Jim from Louisville, KY

Jim builds computers, and he's been trying to get a friend's netbook updated to Windows 10. But it doesn't work with it. Leo says that the computer is probably not compatible with Windows 10. It's a cheaper computer that was designed to work only with the older OS of Windows 8. Leo suspects that the storage memory isn't enough to upload Windows 10 and install it. It's just too lightweight. 

Can I replace the hard drive in my iMac?

iMac

Episode 1629

Steve from Beaumont, CA

Steve bought a new iMac with a Fusion Drive, but it seems as slow as his 2013 iMac. Leo says it is! It's a common problem with fusion drives. Leo says that you could have an SSD installed to replace that Fusion drive. However, you don't want to try and do it yourself because you would have to lift your screen off with a giant suction cup to get to the hard drive. You can go to MacSales.com for the hard drive you want.

How can I use my Android phone with Apple CarPlay?

Apple CarPlay

Episode 1629

Doctor Bird from California

Doctor Bird just bought a brand new Toyota Rav 4, but it only comes with Apple Carplay. How can he get his Android phone to connect and get recognized for navigation? Leo says that is a bad trend, and Sam says that most car makers are making players that will support both. Sam says that if you're ordering a 2019 model, it should support Android Auto as well. If it doesn't, an over the air software update should fix it. The dealer may also be able to reflash the system to give Android Auto support. Also, Android Auto is separate from in-vehicle navigation.

Sam Abuelsamid ... Ultra Wide Band

Sam Abuelsamid

Episode 1629

Sam joins Leo to talk about Ultra Wide Band (UWB) which is coming to mobile phones and cars. The iPhone 11 has UWB, but it's not turned on yet. It's wireless band technology that operates within 6-8 GHz. Google's Pixel 4 will probably have a UWB chip as well. The benefit is going to be that you can directionally connect with devices. It can work with IoT devices, and carmakers will shift to it for keyless entry. It's not uncommon for manufacturers to put hardware into a device even when the software isn't ready, and then turn it on with a firmware update.
