Re-boot camp: the all purpose fix for Amazon gadgets
No gadget functions perfectly all the time.
Even p-books (paperbooks), which were undeniably a technological gadget was first introduced (with “expensive” difficult to use versions going to elite early adopters, and then eventually, cheap mass-produced ones which benefited from early users’ experiences), fail in a variety of ways…pages tear or get folded, spines separate, and so on.
With electronic gadgets, one of the big differences is that they actively do things…they participate in your interaction with them.
That ability to participate has its limits…it can become overwhelmed, just like an adult trying to deal with several children. ;)
Most devices have two sorts of memory, somewhat similar to humans.
They have a short term memory (“What am I doing now?”) and a long term memory (“Who am I?”).
Unless something is catastrophically wrong, a Kindle EBR (E-Book Reader) basically knows it is a device to display books. It knows when you tap a title on the homescreen (I say “tapping” because all of the current generation have touchscreens) it should display that book.
That functionality is in its long term memory.
The words it is currently displaying to you? That’s short term…it can store the spot where you were and return you to that, but it isn’t constantly “thinking” about where you are in all of the books you’ve been reading on the device.
The same sort of thing goes for a Fire tablet, a Fire phone, a Fire TV (or Fire TV stick) and the Amazon Echo.
When its active, short term memory gets filled up, it can’t deal with requests very well…just like that adult with several kids all asking questions at once.
In fact, they can get so overwhelmed that requests can’t reach the long term memory part, or they reach it imperfectly, and it freezes up or makes mistakes.
With electronics, we can usually tell them to clear that short term memory so they can work again.
With humans, we typically do that by sleeping and dreaming…at least, that’s my best hypothesis on dreaming, and it seems to work quite well.
When we dream, we can “run programs” we don’t usually use, to make sure they are working properly, then file them away again. You don’t often have to run through the woods, but you can practice while your physical movements are constrained so you aren’t at risk. Experiments have been done with animals where they can remove the constraint, and yes, the animal will physically act out the dreams (that’s how I recall the studies).
You can “defrag the disk”: run things that happened during the day, deleting fragments, storing some others.
That’s why “sleeping on it” works, and why if scientists keep you from dreaming (but let you sleep), you’ll start to hallucinate within a few days (usually).
We rarely let our devices “dream”, so they can also start to “hallucinate” pretty quickly.
How do you let them dream?
You can reboot them…turn them off and turn them back on it. In the turning off process, they’ll clear all of that temporary memory (but not the long term memory) and “wake up” refreshed.
Oh, that’s important: sleep mode won’t do it here…it’s actually turning off the device.
I have a relative who is a psychologist, and we’ve talked about this. You know when you have a birthday party for a five-year old, and there is a clown and a magician and the presents and the birthday kid falls asleep in the middle?
People tend to say it is “too much cake”, but all the kids had cake. Only the birthday kid falls asleep.
What I think happens is that the brain says, “Too much input!” It shuts down the input systems (by sleeping) to give it time to process what has already been happening. Once things have been cleared up and reorganized a bit, it can wake up again.
With a Kindle or a Fire, you usually do this by holding in the power button.
On non-Fires, if you keep holding it in (for about thirty seconds), it will typically restart on its own.
With a Fire tablet, like my
and the current generation, you may need to release the power button, then press it again to reawaken it.
If you do need to do that, it’s best to leave it off for a bit (a minute should be fine) just to make sure it gets a chance to clear everything.
From time to time, I have to unplug my
to get them to clear up. If you have a way to restart using software, by the way, that’s better. The Kindle EBRs like my
do. Using the software is a “soft restart”. Using the hardware is a “hard restart” (logically enough). The soft restart is simply more elegant and gives the device more control of the process. If it’s too full to control anything, though, then the hard restart is fine.
On my Paperwhite, you use the menu at the top of the screen (tap towards the top of the “page” when you are in a book to see it), then do Settings, then tap the menu again, and you’ll see the choice.
The Amazon Echo reportedly has a reset button on the bottom…mine is on order, but I won’t have it for a while yet.
Restarting should not affect any of the long term memory stuff, like being registered to your account and knowing your wi-fi network password.
In addition to the devices needing this “clearing” process, so can apps on your Fire tablet.
Their active memory is called a “cache”, and you can also “force stop” them to make them shut down and clear everything out.
I find I have to do this pretty often with some apps. For example, the
seems to fill up its cache every few days…and then it won’t scroll through the stories. I clear the cache (and force stop it), and everything is fine again.
How do you clear the cache?
It’s pretty much the same on all the Fire devices…TV, stick, phone, tablets.
You get to the Settings, and then you Manage All Applications (you probably need to select “Applications” first).
Then, you find the app that is “misbehaving”.
You’ll see a choice to clear the “cache”. Clearing it may mean that it takes more time to open the first time, or that it may not know where you were in something (like where you were in a story).
The cache is where it puts the things it doesn’t have to remember forever, just for now. I have described it this way: imagine you are on a shopping trip. As you buy things, you are carrying them in your arms. Eventually, you’ll be carrying so many things, you’ll start to “malfunction”, and may even drop items.
Clearing the cache is like getting those packages out of your arms.
When you go home, you might put them away on shelves in cupboards (depending on what they are).
You can no longer get to them as easily, but your arms are free to do more things and carry more items.
This is not the same as clearing the data, which you generally don’t want to do.
The data choice represents things you want it to remember, in most cases.
I have to validate who I am to the CNN app…I’m allowed to watch it for free because I pay for CNN elsewhere (through my cable company, in my case). I can read the stories without that, but I can’t watch live TV.
That validation is stored in the data, not the cache. I can clear the cache without having to revalidate. If I cleared the data, I’d have to validate again.
“Force stopping” it is like turning it off. That can stop processes that have gone wonky.
Let’s say it is trying to launch a video, but there is something wrong…it can’t do the whole launch. It keeps trying and trying, and can’t think about anything else very well.
The force stop will make it stop trying to load that video…just like shutting down a non-Fire Kindle can make it stop trying to index a corrupt e-book file (such as one that only got downloaded partway for some reason).
I know we shouldn’t ever have to do something like going into Settings-Applications to use our devices, but when I do, I don’t find it onerous…it’s pretty simple and will often take care of whatever the issue is.

* I am linking to the same thing at the regular Amazon site, and at AmazonSmile. When you shop at AmazonSmile, half a percent of your purchase price on eligible items goes to a non-profit you choose. It will feel just like shopping at Amazon: you’ll be using your same account. The one thing for you that is different is that you pick a non-profit the first time you go (which you can change whenever you want)…and the good feeling you’ll get. Shop ’til you help! By the way, it’s been interesting lately to see Amazon remind me to “start at AmazonSmile” if I check a link on the original Amazon site. I do buy from AmazonSmile, but I have a lot of stored links I use to check for things.
