- Let's talk power and the speaker for a laptop.
And I have a closeup
of the power brick that this Toshiba laptop uses
and also the battery.
And when you, if you need to replace any of these
let's say the power brick goes bad.
For some reason, or the DC Jack portion
of the power brick gets damaged,
for some reason, you'll have to replace this.
You gotta replace it with the same exact part number.
So you gotta locate that and here it shows you
Toshiba part number PA5177U-1ACAACA.
And that's important because this particular power
supply is going to use a specific voltage and
amperage rating and that's down here and
that's 19 volts and 2.37 amps.
Now, even if you were to find another power
pack that has the same specifications as this, I
wouldn't recommend using it for a couple different reasons.
Always go with the same exact power pack
make sure you get the right power brick
from the manufacturer.
And over here, we have the battery.
This is close up of the battery,
and you'll see the voltage is actually different for this,
and that's because the power is actually converted
as it goes through the system.
But if you need to replace the battery
which is more likely than the power pack, you know
you're gonna be using a li ion battery from Toshiba.
You want to get the manufacturer battery
and make sure it's the exact right.
The model number for this PA5195U 1BRS.
- Here's another technical tip for you, make sure
that your laptop is turned off and
that the power is disconnected before you change
out the battery or do any work with the battery
make sure that it is disconnected.
- And again, you don't want to swap batteries
out with other laptops, but generally you can't
because almost all the batteries are a different size
and shape. So that's not really gonna be possible.
So those are your two items there
with the power brick and the battery.
You know, the battery could be a ... you know
that can go bad over time because it only
holds so many charges. It could be damaged.
There's a lot of possibilities with that.
And this port is actually soldered onto the board.
So if this port was to go bad, you'd have to
re-solder a new one or replace the whole board
which you know, can be a bit difficult.
Usually that doesn't go bad.
So that's not usually a problem.
What's more likely to go bad is the DC in-jack.
And that's right over here, this guy right here.
And that's because when people connect to the
DC in-jack quite often, they'll, they
might wiggle the connection or jiggle it in there.
And you know, it could cause damage over time.
In the past, this DC in-jack was
soldered to the motherboard.
And if that's the case
it could be a bit of a difficult fix.
But in this case this guy
just pulls right out and just has a connector.
So we can actually take that guy
and just pull him straight out of there.
And then he's just got a connector here
and you can pull that right out.
And so you see it's just a typical 4-pin connector
and you could swap out the whole DC in-jack.
This is part number ST5034.
So that's the guy I would use for that.
Real easy change out.
And that's a good thing for it Toshiba.
Good thing for the laptop industry
in general that it's not soldered onto the board
because they do get damaged fairly frequently
just because of the wiggling of the jack, where
maybe someone leaves the jack plugged in ...
the power brick plugged into the laptop
and then puts it in a laptop bag.
And it goes on transit or goes
on a plane and who knows what happens.
And it shifts around in there and damages the plug.
And sometimes these just go bad in general.
So easy repair for that.
So there's another portion of the power
and I've turned the laptop 90 degrees clockwise
and we're looking at the corner here.
This is where the power button is underneath.
If the power button was to fail, all you'd need to
do is disconnect this little connector here
and then remove this little tiny circuit board.
That's where the power button is right
underneath this connector.
And there's a little a little sticker here
that you can remove and then a screw to take off.
And that's basically it you'll get the replacement part
for that and you can get a replacement button as well.
Sometimes they're sold together as a kit.
So that's another thing that might fail the power button.
Sometimes people hit it too hard
or it just fails over time due to usage or what have you.
So that's pretty easy fix also.
All these fixes though you know,
they require opening up that case at a laptop.
So again, if you have a warranty, make sure you check first
if you open a case, you're gonna void that warranty.
If you do have one.
And so that's pretty much everything you need to know
for power for the exams, you've got your power button
you've got your power brick, you've got your battery
you've got your battery connection.
And you've got that DC in-jack as well.
Very important.
The last thing I wanna talk
about real quick was the speakers.
Sometimes the speakers will fail
not quite as often anymore, but on a typical laptop
like this, it's considered a stereo system
which means it has two speakers and they're
in little housings and
you can pull those housings right off
and you can see, there you go.
There's your speaker.
That's right.
That's a speaker.
And that's why stuff sounds pretty tinny
on most laptops because the speaker's tiny
but that just connects with two standoff screws.
And the other one here is the same thing.
It's got two standoff screws as well
and both of these connect to this connector.
So if one speaker fails
really you're gonna have to replace both of them as a kit.
You could try to solder
on two wires onto the connector,
but I wouldn't recommend it.
It's gonna come as a kit with both speakers and this
this connector here, which will plug back into this.
So that's a pretty easy fix too.
You really just pull these
off, pull both off and replace them.
Make sure that you're doing it for the exact laptop though
because you know, this is, I believe an E45.
And even the difference between this model
the E45 and the E55 has a different design of speakers.
So, you know you gotta make sure
you're getting it for the exact model.
And so again, if the speakers fail, that's it
you're gonna replace both speaker housings and
those connected to the plug.
Here, there's a little piece of tape.
that's just covering up this and holding the wire down.
So that's the only reason for that.
And so that's basically it, that's your power
and your speakers pretty easy fixes for most of these
the main key here is compatibility.
Remember to use products that come from the
manufacturer and that they're the right model, excuse me
the right part number for that particular model of laptop.
