- [Instructor] And part four
of the mobile device troubleshooting.
Non-responsive systems could be caused by several things
including extremely short battery life.
Well, if the battery was damaged
or it's shelf life has pretty much expired
or it won't hold a charge,
well, then the system's gonna become non-responsive.
It's gonna be slow
and the battery won't last very long
for you to even work with it.
So generally, a new battery is necessary,
but it could be also that you have applications on there
that are using a lot of power
or it could be that lack of airflow to the battery
and it could be a virus or malware.
So you're gonna wanna check your anti-malware software
and see if it is running first of all
and also see if it's updated.
Overheating is a huge problem with batteries.
I don't know, I've heard people say that their batteries
overheat a ton of times,
and this could be because of bad applications,
poorly written applications,
the excessive use of applications
where you have tons of applications
running at the same time,
excessive browsing where you have 15, 20, 25 tabs open
at the same time 'cause that's easy to miss
for the average user as well.
Could be an old battery, a damaged battery,
lack of ventilation.
There's a lot of possibilities for that.
Always remember, avoid draining the battery,
especially below 50%.
Try to conserve power. Use sleep mode.
Keep your device away from heat sources.
Turn off the mobile device when not in use.
Don't bang or throw the device.
Use a good case around the device
so that it doesn't overheat, so you get that proper airflow.
Clean your device every couple months.
All these things can help with overheating.
Remove unnecessary applications
and close applications that you're not using
and force close them if necessary.
All these things can attribute to overheating,
so watch out for that.
And you might see a frozen system as well.
The frozen system is pretty much the worst
because you can't do anything.
You can't try to fix it.
You can attempt to force close applications.
You can attempt to reboot the system
and go into safe boot mode.
You can attempt to do a Control + Alt + Delete
on your laptop and see if you can get into the task manager
and end the process or app that is causing the problem,
but sometimes none of that works
and you have to just try and restart the system
and you might have to pull the power.
You might have to pull the battery.
So a frozen system could be a big problem for you.
Now, frozen systems will generally mean
that the CPU was too overworked
or the battery doesn't have enough power
and it's running low on battery life
and the CPU usage is way too high.
And quite often, a frozen system
is accompanied by overheating.
So it's kind of an interesting little phrase there.
The frozen system usually happens
when the mobile device is very hot
and you'll feel it on the back of the device.
So the best thing is again you wanna try
and kill off any applications that aren't necessary
and reboot the device, power cycle it.
And if a regular reset doesn't work,
you're gonna wanna consider a hard reset
on the smartphone or on the tablet.
Make sure your information is all backed up.
See if that fixes the problem for you.
Now with Windows, you get into frozen systems
and it could be a lot of reasons
and there could be files that are corrupted.
There could be issues with the operating system.
We get more into that in the 902 course,
but it's the same type of thing.
You wanna check the connections for power,
check the battery and power cycle the whole device
and see if it happens again.
And if it does,
then you're gonna have to troubleshoot further.
You might have an issue with the CPU.
The CPU might be overheating.
You might have an issue with the fans.
The fans might not be ventilating
the heat out of the system properly
or maybe the fan got disconnected or maybe it just failed,
so there's a lot of possibilities with that.
But generally, you wanna keep your device maintenanced
and you wanna try to verify
that the battery is relatively new
and you have cleaned up your applications
and you've tried a reset.
You've tried re-imaging the laptop
or you've tried a hard reset on the smartphone or tablet
before you go any further
and attempt sending the laptop back to manufacturer
or taking the mobile device to an authorized repair center.
Always check those things first.
And so that's about it for the troubleshooting
for the mobile devices.
