- Okay, part two of mobile device troubleshooting.
Here are some more common issues you might encounter.
For example, the battery doesn't charge.
Well, that's a problem.
If the battery doesn't charge
then you won't have long to go before it dies out
and you won't be able to use the device.
Now, for the laptop,
you wanna check and make sure
the battery is connected properly.
And you wanna check that your power brick is connected
to your DC in jack correctly.
And, you know, check that the power brick is,
the connections are secure on both sides:
the AC outlet, the power brick itself,
and then the connection to the DC jack.
And you wanna make sure that you're using the correct
battery charger for your laptop.
Very important.
Sometimes the DC in jack can go bad, it can be damaged.
And we showed how you can replace that in a previous lesson,
so you wanna check for that as well.
Otherwise the battery might be dead as well.
Batteries for laptops,
they usually have a shelf life of about five to ten years,
depending on the usage of the laptop.
And on the mobile devices,
your battery life is a lot less:
it's usually two to five years.
Less amount of time for smartphones and
more for tablets but,
the battery might not charge on a smartphone or tablet
because your charger isn't working properly
or it's the wrong charger.
And again, the battery could go bad over time.
So, you wanna check that.
Now, there's other options.
There's, there's other possibilities,
as far as the battery.
You might have a swollen battery.
When this happens, if you see it,
you have to, you know, remove it immediately.
Put it in a Ziploc bag and inside a cardboard box
and recycle it as need be.
Your municipality will have regulations as far as
how this is done.
And there's a lot of companies that are out there
that will come to your organization
and pick up these types of swollen batteries
or damaged batteries and just get them
out of your business real quick.
But the swollen battery could happen because of over usage.
It could be a very old battery.
It could be because of temperature issues.
You know, you, you might be bringing the device
from cold climates to warm climates quite often.
Temperature and humidity changes could cause this.
And especially damage to the battery:
if you've dropped the smartphone or the tablet,
you could get a swollen battery.
So, you wanna watch out for that.
And that'll usually cause it to overheat
or cause no power at all.
So that no power, if you get no power at all on the device,
you gotta check the battery.
You gotta check the connections.
You gotta make sure that the device is taking a charge.
So we wanna watch for that amber light.
You know, you might have an amber light here,
that says it's charging,
which will turn green when it has completed.
Or you might have the amber light here on the laptop.
And if you see a red light, that usually means an issue.
Either, either there's a bad charger or a bad battery.
So, watch out for red lights.
You shouldn't see those if it's functioning properly.
And again, always check the power button,
the power connection.
I actually,
when I took apart this laptop
in a previous sub lesson,
I forgot to reconnect the power button.
And I, I plugged it in and it wasn't turning on.
And I was like, "Oh,
I thought I was pretty careful with the device."
I was like, "Well, gotta reopen it again."
Which takes another five minutes
'cause there's a million screws and everything.
But that power button was disconnected, and I was like,
"Wow, I can't believe I did that."
And it, it happens.
So, check the power button, if you have to,
if you get a no power issue.
Let's say the number lock indicator light is on
or is causing issues with your system.
You might have a num lock light here or over here,
and you're gonna wanna check that because on some laptops,
the num lock will cause these letters here
to also act as numbers.
And we talked about this.
You may have to turn the num lock off to get all letters.
So, you wanna watch that num lock indicator light.
That's an issue sometimes when people are typing,
they're not getting the right characters on the screen.
And no sound from speakers:
well, you wanna check if first of all,
you wanna check if the sound is on.
On the laptop here,
you have your volume buttons and your mute button.
And you have your volume buttons here,
volume down and volume up on this smartphone.
And you can change the volume from within here as well.
And don't forget, we said that you have multiple volumes.
You have your master volume on most smartphones and tablets.
But then if you tap on that,
you have individual volumes for different applications.
And, you know, you might have that for the laptop as well.
You have your mixer.
If you click on the sound icon in the notification area,
you have your mixer and your different volumes for say,
your browser and different applications you're running,
and for the system sounds as well.
So you wanna check that stuff,
see if it's muted on the function keys here
or within the operating system in the notification area,
or on screen in your settings area.
Or just hit your volume buttons here to find out.
And then you can troubleshoot further.
Maybe the sound device is disabled in the device manager.
Or possibly there's a loose connection for the speakers
inside the laptop.
