Inaccessible backups, and a dead laptop

How can you repair what you can’t get at? Today’s column covers two problems caused by very different access issues. In one case, a subscriber is locked out of her old, obsolete backup files; she can neither access nor delete them and thus cannot recover the huge chunk of disk space they occupy. In another,…

Sudden, uncommanded shutdowns plague Win10 laptop

AskWoody subscriber John Mackin’s laptop was badly malfunctioning, and the problem remained unresolved even after some top-notch troubleshooting and maintenance. “Fred, I have a three-and-a-half-year-old laptop (Dell Inspiron 13”, i7, 12 GB RAM, 1TB M.2 SSD, Windows 10) that has recently begun to periodically shut down during use. “Suspecting CPU overheat, I downloaded the CoreTemp…

“Why is there no considerable technical development in laptop and phone chargers over the years?”

(Answer requested by Prapat Saxena) I disagree with the premise of your question. Most charging is by USB these days. When USB 1 came out in 1996, it supported 5 volt/0.5amp charging; 2.5 watts. Today’s newest USB charging supports up to 20 volts/5 amps; 100 watts. And there are now wireless charging options, too. I’d…

“Today I hit my laptop because I got angry…”

The note from “K.A.” was confessional and a bit anguished: “Today I hit my laptop because I got angry and I’m stupid. The screen glitched and it just rebooted. It went back to work just fine, but I’m paranoid. Did I cause damage? It’s an old Acer.” The four tools you’ll need to find and…

“What is the difference between sleep, hybrid sleep, and hibernate on a laptop?”

(Answer requested by Shreya Mehta) In sleep mode (sometimes called suspend), your PC goes into a low-power state, consuming just enough electricity to keep the RAM contents intact; to monitor for system events (such as a key- or mouse-click, or closing the lid on a laptop); and to run similar low-power processes. The major advantage of standard sleep…

“When I am typing on my laptop, my cursor sometimes ends up somewhere else on the page. Is this a computer or website issue?”

(Answer requested by Katherine Quinn) My first guess is that it’s a purely physical issue with your laptop. For example, one of the reasons I use an external, plug-in keyboard on my laptop is because my thumbs used to occasionally brush the laptop’s touchpad as I typed on the built-in keyboard; I wouldn’t feel the…

“Do you need a laptop if you don’t often take it with you places?”

(Answer requested by Benjamin Woods) Laptops and notebooks don’t have to travel at all to be useful. I use a laptop as my main PC, and it’s never been out of the house. I like a laptop because it’s smaller, quieter, and uses less energy than a desktop PC. I like that I can close…

“Why is my Lenovo laptop shutting down after 5 to 10 minutes of working?”

(Answer requested by Chandrakant Godhani) Assuming the battery is charged and OK, or the laptop is plugged in to a known-good power supply, the most common cause of “PC runs for a while and then stops” is heat buildup: Some component is running hot, and the PC is shutting itself down to prevent permanent damage…
