Technically Correct vs. Practical: Can Rechargeable Batteries Overheat Or Not?

Its battery shouldn’t overheat, but that doesn’t mean it can’t. From time to time I’ll get a comment or email from a tech-savvy person who’s read my post, Rechargeable Battery Problems: Overcharging, Leaving It Plugged In, and says I’m wrong about the possibility of rechargeable batteries becoming overcharged or overheated, because modern Lithium-ion rechargeables are designed with specific features to prevent this very problem. Every so often I’ll also get a note from an engineer or scholarly type saying one of my other posts isn’t technically correct for some esoteric reason or other. But I’m not here to provide technically correct details that would satisfy the most stringent engineer or scientist, I’m here to help consumers get the best and most economical use from their devices.

Where Did My Download Go?

When you download something off the internet, it’s not always obvious where your computer decided to stash the file. Even when the browser prompts you to specify a location to save the file to, sometimes the computer just goes ahead and saves that file to some other mystery spot among your files and folders, and you’re stuck having to hunt it down. My Dad ran into this problem when I sent him a redemption code for a digital video I’d bought him, and he had to redeem that code right on the performer’s website. He thought he’d downloaded the video, but when he went to check his My Videos folder, he couldn’t find it. Here are some tips and tricks for finding those pesky, missing downloads. Going On A Download Hunt Downloaded files don’t always go where you assume they should.

Can My Overcharged Battery Be Fixed?

I’m sorry to tell you this, but in a word, no. It doesn’t mean your device is totally useless, however. I’ve written here before about the dangers of overcharging your thingie’s rechargeable battery, and more recently I’ve been getting questions from site visitors about what to do once that damage is done. Before we go any further, see this post for a simple rechargeable battery test you can do at home with no risk to yourself or your device. If the results show your rechargeable battery is damaged, read on. 1. If your thingie is still under warranty, return it to the place where you bought it for a replacement. If you’re going to replace it with the exact same thingie, back up your content first so you can re-load everything onto the new device. Click here for my post that explains how to do this for a Kindle Fire. For other types…

When And How To Stop Sharing A Family Account For Your Digital Content

Many of you may have grown kids starting off in college or permanently moving away from the family home, and you might be wondering if it’s the right time to break up your family digital content accounts (e.g., iTunes, Amazon Instant Video, etc.). The answer is: it depends on your specific situation. But after reading this post, you should have all the information you need to make an informed decision. A Single Family Household Can Share Content From an earlier DMM post, Can I Share Content From My Thingie?: Apple Thingies: Apple Content Is Controlled Through iTunes Every individual Apple thingie (iPad, iPhone, iPod, etc.) is tied, or registered, to a specific Apple iTunes customer account and content library (music, movies, podcasts, apps, etc.). A single iTunes account can have multiple Apple thingies registered to it, and everything in that iTunes library is available to all the thingies registered to that…

Do You Need To Worry About the FBI Ransomware / FBI MoneyPak Virus On Your Mobile Thingies?

I recently got a question about The FBI Ransomware Trojan, which is also known as the FBI MoneyPak virus. A commenter raised the question in the comments section of my earlier post, Does Your Kindle Fire Need Virus Protection? What’s “FBI Ransomware”? This specific Trojan / virus is an especially nasty one, as it essentially locks you out of your computer or mobile device until you pay whatever fee it’s asking in order to release the lock. It’s got “FBI” in the name because the extortion pop-up says the FBI has identified some kind of threat on your machine and will remove it in exchange for a fee, usually $100, to be paid by credit card. So these hackers get $100 immediately, plus the duped consumer’s credit card number. Making matters worse, making that payment won’t necessarily unlock your computer or device. Even if it does work, it’s only a matter of…

How To Delete Apps From The Cloud On A Kindle Fire

In a past DMM post, Kindle and Kindle Fire Owners: Where Your Content Lives and Deleting, Moving and Restoring Kindle / Kindle Fire Content, I explained how to delete apps and other content from your Fire vs. from the Cloud, and what the difference is between the two. Today I’d like to update that post with some new information: how to delete an app from Amazon’s Cloud right from your Fire**—all models, from first-generation non-HD to the latest HDX line—, without logging on to the Amazon site. **UPDATE** 5/19/15: while this post reflects information that was provided by Amazon at the time the post was written, more recent tests have shown the method described here doesn’t work for first-gen Fires. For people who only own first-gen Fires, the only way to remove apps from the Cloud in on the Amazon site itself. First, I must remind you: anything you delete from the…

The Differences Between Wi-Fi, Bluetooth and Cell Connectivity

Bluetooth speakers, 4G tablets and external hard drives with Wi-Fi, oh my! Here’s how these three types of connectivity technologies differ. Wi-Fi Wi-Fi is the type of connection you need to wirelessly connect various devices to a wireless network. It could be your home network, the network at your workplace, or the biggest global network of them all: the internet. Yes, the internet is a network. It seems obvious when you realize that a network is just a collection of technology devices that are all set up to communicate with one another. So where at home, you use a network to send a document to a printer that’s located far from your computer, on the internet, computers and servers send web pages, files and messages to other computers and servers that are located as far away as the other side of the world. So if you’re considering buying some device, and…

Kindle Fire HDX Antivirus – Do You Need It?

I’ve previously written about the pointlessness of antivirus protection for the Kindle Fire line of tablets (see my post, Kindle Fire Antivirus: You Still Don’t Need It), but the new HDX line of Fires adds a new wrinkle since they all come with the option for 4G cell service connectivity. In my prior posts on this topic, I discussed how some hackers target cell phones specifically to add bogus charges to the phone owners’ bills. Many, if not most, cell phone owners won’t notice small charges scattered across an entire month, but they add up quickly. Some hackers go for broke right out of the gate and try to make a single, large bogus charge to the phone owner’s bill (usually masquerading as some kind of pay-by-the-minute service, like a party line or psychic reading service). They sometimes get away with it because these types of charges are made to the phone owner’s account immediately…

Upgrading To A New Kindle Fire: How To Copy Content From An Old Fire To A New One

In my previous post, Surviving A Kindle Fire Factory Reset – With (Most) Of Your Stuff Intact, I outlined a step-by-step process for backing up your Kindle Fire before performing a factory reset, then restoring that content after the reset. Now that the new Kindle Fire models are upon us, I’m getting this question pretty frequently: can the same method be used to transfer content from an old/pre-existing Kindle Fire to a new one? The answer is: yes, but with some tweaks to the process. When I got new Fire I was able to test this out for myself, so I can confirm that it works. A Step-By-Step Process For Relocating To A New Kindle Fire The steps below, and screenshot, are from going through this process with a Kindle Fire HD model. The process is essentially the same for all Fire models, but folder names and locations on different generations…

What’s The Difference Between SD And Micro SD Memory Cards?

I won’t bore you with all the technical details of what makes a micro SD card different from a standard SD card, because I’m pretty sure all you care about is whether or not a micro SD card will work with your various devices. The answer is, so long as your device can accept a standard SD card, yes, it can accept a micro SD card — provided you have a standard SD card adapter or USB plug-in adapter (as pictured in this post). You can buy micro-to-standard SD card adapters and USB plug-in adapters on their own, but plenty of micro SD cards come bundled with adapters, too. To use a micro SD card in a device that takes standard SD cards (most digital cameras, for example), you just slide the micro SD card into the adapter’s card slot, then insert the adapter into your device the same as…
