“How do I stop the CBS All Access app from lagging so much when I Chromecast it to my TV?”

Good luck. The CBS app is horrible! My wife has an iPhone with the Apple version of the CBS app; I’ve used the Android version of the app on two different, current Samsung phones; and have also used the CBS app built into my smart TV. On all platforms, the app’s native resolution is meh,…

“I know to de-fragment my HDD and not to de-fragment my SSD. Do I de-fragment my hybrid drive?”

It’s a quandary. Solid-state/hybrid drives (SSHDs) use a modest amount of high-speed memory as a kind of front end to a large, conventional, spinning-platter drive; software makes the two act as one. The idea is to yield a drive that’s faster than a conventional drive, but less expensive than an all-solid-state drive. But, as you…

“If you could only have a smartphone or a laptop for the next 5 years, which would you choose? Why?”

I’m glad I don’t have to choose! But if I did: I’d choose a high-end, state-of-the-art smartphone. Why? Because you can turn a high-end smartphone into a pretty capable notebook-equivalent by adding a USB- and Bluetooth-connected monitor, keyboard, and mouse. But while a smartphone can serve as a portable PC, the reverse isn’t true: For…

“Is it OK to leave a portable external hard disk plugged in and active 24/7?”

(Answer requested by Diego Gerardo Velasco) If the drive is simply on — fully powered up and spinning, even while it’s not needed — you’re wasting energy, and putting needless wear on the drive bearings. You’re also exposing the drive electronics to extra risk from electrical problems (spikes, surges, sags, etc.). If the drive is…

“How can I retrieve a copy of a document from the hard drive in the office copy machine?”

Not all copiers have hard drives (it’s generally only higher-volume copiers that need to queue, track, and manage numerous large print jobs); and not all copiers with hard drives work the same way. But, in very broad terms, and depending on whether you’re trying to do something above-board or not, here are two approaches: If…

“If you could only do one computer upgrade when you purchase a new computer, would you upgrade RAM, processor, or storage?”

(Answer requested by Mandi Bailey) If it’s a brand-new PC, odds are it’ll have a reasonably current, capable CPU; and an at least acceptable hard drive. But most PC baseline models have only a modest — sometimes minimal — amount of RAM. So, if I’m allowed only one upgrade, I’d go for more RAM —…

A reader asks: “My laptop screen is upside down. How can I fix it?”

(Answer requested by Daniel Price.) If you have a more-or-less normal PC running more-or-less normal Windows, you can flip the screen orientation — up, down, sideways right, sideways left — just by tapping a few keys. It’s possible you accidentally hit one of these key combinations. (They key combinations are deliberately weird to make them…

A reader asks: “Why am I not able to reset my PC or reinstall Windows?”

(Answer requested by Reese Lynn.) The most common problems include obsolete drivers (check your PC vendor site for updates); too-aggressive third-party software (e.g. anti-rootkits/anti-malware); and disk errors (run chkdsk ). For some general how-to fixes, see this text; it mentions Win7, but the general fixes discussed there work on any Windows version. Also, Google/web-search for the…

A reader asks: “Why is there a need for separate RAM and hard drives?”

Speaking very generally: RAM is very fast, temporary data storage used only while the device is powered on. The data in RAM goes away when you turn off the device. Hard drives are for storing data longer term; they retain data even when powered off. But hard drives — even solid state drives! — are…

A reader asks: “Can I mount my hard drive sideways/upside down?”

Reader Met Chin asks “Can I mount my hard drive sideways/upside down?” Sure! Unless the owner’s material states otherwise, most desktop/rack-mount/non-portable drives work fine flat (right side up or down), or on end, or on one of their sides. Everything else being equal, as long as the drive’s platters are parallel to the floor, or…
