-: In this lesson, I'm going to show you
how to replace a battery inside of a laptop.
Now, every laptop is going to be a little bit different.
For example, some laptops have the ability
to change out the battery on the outside of the case
such as that older Dell, that I showed you.
But most of them now use an internal battery.
And the reason for this is in the old days
batteries only lasted two or three hours.
So it's pretty common
for people to carry two or three batteries with them
so they can make it through the day.
But most modern laptops can now support
a 10 to 12 hour battery life,
depending on the model you're using.
And some even have what's known as an all day battery life,
that last anywhere from 18 to 24 hours.
Unfortunately, over time though
this battery does become worn
and it can start to lose its charge.
So you might need to actually replace that battery
with a newer one to give this laptop new life.
In order to do that,
you're first going to disassemble the laptop
as you see here and have it open
so you can start working on it.
Then you'll locate where the battery is.
You'll buy a replacement for that battery
of the same make and model.
And then you're going to unscrew this battery, unconnected it,
and then replace it with the new one.
I'm going to show you how to do that right now.
All right.
The first thing we need to do is grab our screwdriver
and our ESD strap, and then we want to make sure we identify
where the screw holes are.
There's one here, one here, one here,
one here, and one here.
So it looks like we only have four screws.
I'm going to go ahead and start here and unscrew this one.
So I'm going ahead and I'm unscrewing all four screws
and then they are small screws,
so if you have trouble grabbing them,
you can use a pair of tweezers to get them.
That first one, I had a hard time grabbing.
So I'm going to go back
with a pair of tweezers to get that out.
There we go.
And because I'm doing this pretty quickly
there's only going to be, it looks like there are five screws.
I'm just going to lay them out on my board here
in the position that I took them out.
So that we'll know where they go back.
Or again, I can use something like I did up here
where I have my magnetic case
that I can write on with a dry erase marker,
so you'll know exactly which screw goes in which place.
But since we're going to be doing this fairly quickly
I'm just going to make sure I put that into the right place.
And this last one is going to come up here
and we'll put that there, okay.
So when I'm done
that is essentially where my screws are going to be.
It looks almost like an L shape.
Now that I've gotten all the screws out
I want to make sure the battery will come loose.
So I'm just going to put my fingers
on the battery and give it a little wiggle
and you'll notice it does come loose
because I've gotten everything out
but it is still connected someplace.
And it's underneath this little plastic shield.
So I'm going to put the battery back down,
I going to lift up this plastic shield off to the side
and you can see that the battery plugs into this connector.
To be able to unhook this, I'm simply going to use my tweezers
and put it into place
and just apply a little bit of pressure
to be able to bring that back out.
And there we go.
Now I've gotten that out.
I can take the whole battery and pull it out.
And so you can see that battery is now out
and we'll be able to replace it with a new one.
All right, next, I'm going to grab a new battery.
And once I have my new battery
I'm going to verify it is the same make and model,
in this case, it is.
I'm going to line it up into the proper position
and I want to make sure I get that connector back in first.
So I'm just going to line that up with my fingers
and I should be able to just push it in with my thumb.
And if I can't do that
I can always go back and use my tweezers.
And in my case, I'm going to go ahead and use my tweezers
because it wasn't working with my thumb.
And you'll notice you want to make sure you get that
right in there all the way in,
so that makes a good, solid connection.
Once that happens, line the rest of the battery back up
make sure your holes are in the right place.
Put your little plastic shield back in place.
There's a little bit of sticky glue on that.
And then we'll just screw that battery back in.
When you're screwing your battery back in
make sure you're using the right screws in the right holes.
This is why it's important to always label your parts
as you're taking them out or do some sort of way like I did
where you made basically a little diagram with your screws
and then you'll be able to screw them all right back
into the proper places.
And once we're done with that
we will reassemble this laptop.
We will make sure the battery is taking a charge
and we'll make sure that the computer can be charged
from that battery and it provides power
from the battery back to the computer.
Now, in my case, we're not going to do that right now
because we have other components we want to take out
and replace in this section of the course.
But if you were done with this repair
you would be able to put the computer back together
by reassembling it, putting the backing case back on,
and to make sure that all of these screws
are being put right back into place
to hold that plastic backing of the case
into the proper position
and making sure it won't go anywhere.
Once that's done,
you can give the computer a laptop back to your end user
and you'll be finished with that particular job.
