First, check to see if your whole Mac has turned off, or just the
screen. Is it still making noise? Does the Caps Lock key still light up?
Does pushing the Power Button making a chiming noise? Then the issue is
probably with your screen, and you should skip to the next problem on
our list.
If your MacBook is truly off and refuses to turn on, then check for
any power problems. Cover the basics first. Is your battery charged?
Does your laptop work when the power cord is plugged in? Does an extra
power cord work? This indicates a problem with your battery or power
cord. You should also disconnect everything (including your mouse,
mobile devices, etc.) from your MacBook and see if that helps fix the
problem.
Reset your MacBook. You can reset simply by holding down the power
button for at least ten seconds. Then push the power button again as you
would normally to see if your Mac turns back on.
Sometimes an important new upgrade like new memory can freeze your
MacBook in permanent “uh-oh” mode. This is rare for the Air, which is
built with a very compact design and resists most modding attempts.
However, if you have added memory or other capabilities via external or
internal work, note that removing upgrades may solve your problem. The access to Apple’s instructions may help here.
Can’t Connect Android to a Windows PC - problems with android 2016
There’s two ways (there used to be three) that Android connects to a computer: Android Debug Bridge
(ADB) or Media Transfer Protocol (MTP). ADB lets users interact with
Android’s operating system while MTP only permits access to specially
designated media storage directories. ADB always causes the most amount
of problems.
I have a full-length article on how to fix ADB in Windows. More or less, it’s just a matter of installing Koush’s universal ADB drivers. Read the complete article in case that Koush’s drivers aren’t enough.
The Nuclear Option
If all else fails, and you’ve even turned to search engines for help,
there’s still the Android equivalent of the nuclear option: a factory
reset. To perform a factory reset go to:
How do I Free up Memory on My Android Device? problems with andoid 6
By memory, you might be referring to RAM. The Android operating
system works best with a minimal number of installed applications.
That’s because some apps like to run in the background, even when you
don’t actually use the app. The more apps installed, the more likely it
is that some will run wild in the background. The simplest solution is
to uninstall all non-essential applications.
We do not suggest using an app killer as this will negatively impact the functionality of some of your apps.
Some imported tablets and smartphones don’t come with the Google Play Store. Users will need to locate an APK (Android installable file)
from a third party source and then manually install it. Before getting
started, you’ll need to enable third party sources. To do so, go to:
Settings
Security
Then check the box for “unknown sources”
Once checked, you can install the Play Store. Here is a link to a legitimate Play Store APK: Download Google Play Store.
You can’t uninstall the Google Play Store without root acces (what’s root?). Most users who think they’ve deleted Google Play actually have disabled it. To reenable the Play Store, go to:
Settings
Apps
Swipe right and locate the “disabled” tab.
Then locate Google Play Store. You can reenable it by tapping on the icon that says “reenable”.
Sometimes Google Play won’t install applications. There’s two kinds
of popular fixes. The first is to wipe Google Play’s cache. The second
is to erase Google Play’s history.
Wipe Google Play Cache
In my experience, the best fix is to wipe Google Play’s cache. Go to:
Settings
Apps
Swipe right to locate the “all” tab
Locate Google Play Store and wipe cache and data
Restart your phone
Wipe Google Play History
I’m skeptical about this fix. However, for those desperate, give it a shot. Here’s how:
Android allocates fixed storage space for apps. Users can’t
expand it. So you might run into this error even if your device
indicates a great deal of remaining storage capacity.
The easiest way to free up space is to begin uninstalling apps.
However, if you use music apps, like Spotify, you might not be able to
find where the files are being stored. The quickest way to free up space
is to use an app like CCleaner.
If you want to get a visual display of where all your memory is going, try using DiskUsage. It will visually display your files’ locations and size.
