1
00:00:06,870 --> 00:00:10,620
- Let's talk power and
the speaker for a laptop.

2
00:00:10,620 --> 00:00:12,240
And I have a closeup

3
00:00:12,240 --> 00:00:17,240
of the power brick that
this Toshiba laptop uses

4
00:00:17,520 --> 00:00:19,293
and also the battery.

5
00:00:20,250 --> 00:00:23,250
And when you, if you need
to replace any of these

6
00:00:23,250 --> 00:00:25,080
let's say the power brick goes bad.

7
00:00:25,080 --> 00:00:27,930
For some reason, or the DC Jack portion

8
00:00:27,930 --> 00:00:30,090
of the power brick gets damaged,

9
00:00:30,090 --> 00:00:32,250
for some reason, you'll
have to replace this.

10
00:00:32,250 --> 00:00:35,070
You gotta replace it with
the same exact part number.

11
00:00:35,070 --> 00:00:37,698
So you gotta locate that
and here it shows you

12
00:00:37,698 --> 00:00:40,997
Toshiba part number PA5177U-1ACAACA.

13
00:00:43,710 --> 00:00:47,730
And that's important because
this particular power

14
00:00:47,730 --> 00:00:51,570
supply is going to use
a specific voltage and

15
00:00:51,570 --> 00:00:54,960
amperage rating and that's down here and

16
00:00:54,960 --> 00:00:57,723
that's 19 volts and 2.37 amps.

17
00:00:58,740 --> 00:01:01,110
Now, even if you were
to find another power

18
00:01:01,110 --> 00:01:06,110
pack that has the same
specifications as this, I

19
00:01:08,160 --> 00:01:11,010
wouldn't recommend using it
for a couple different reasons.

20
00:01:11,010 --> 00:01:14,790
Always go with the same exact power pack

21
00:01:14,790 --> 00:01:16,500
make sure you get the right power brick

22
00:01:16,500 --> 00:01:18,150
from the manufacturer.

23
00:01:18,150 --> 00:01:21,120
And over here, we have the battery.

24
00:01:21,120 --> 00:01:22,800
This is close up of the battery,

25
00:01:22,800 --> 00:01:24,930
and you'll see the voltage is
actually different for this,

26
00:01:24,930 --> 00:01:27,840
and that's because the
power is actually converted

27
00:01:27,840 --> 00:01:29,580
as it goes through the system.

28
00:01:29,580 --> 00:01:31,530
But if you need to replace the battery

29
00:01:31,530 --> 00:01:34,530
which is more likely than
the power pack, you know

30
00:01:34,530 --> 00:01:38,160
you're gonna be using a li
ion battery from Toshiba.

31
00:01:38,160 --> 00:01:41,400
You want to get the manufacturer battery

32
00:01:41,400 --> 00:01:43,080
and make sure it's the exact right.

33
00:01:43,080 --> 00:01:45,993
The model number for this PA5195U 1BRS.

34
00:01:49,560 --> 00:01:52,020
- Here's another technical
tip for you, make sure

35
00:01:52,020 --> 00:01:54,720
that your laptop is turned off and

36
00:01:54,720 --> 00:01:57,526
that the power is
disconnected before you change

37
00:01:57,526 --> 00:02:01,050
out the battery or do
any work with the battery

38
00:02:01,050 --> 00:02:02,973
make sure that it is disconnected.

39
00:02:04,110 --> 00:02:06,840
- And again, you don't
want to swap batteries

40
00:02:06,840 --> 00:02:09,376
out with other laptops,
but generally you can't

41
00:02:09,376 --> 00:02:12,390
because almost all the
batteries are a different size

42
00:02:12,390 --> 00:02:15,960
and shape. So that's not
really gonna be possible.

43
00:02:15,960 --> 00:02:17,790
So those are your two items there

44
00:02:17,790 --> 00:02:19,800
with the power brick and the battery.

45
00:02:19,800 --> 00:02:21,450
You know, the battery
could be a ... you know

46
00:02:21,450 --> 00:02:23,640
that can go bad over time because it only

47
00:02:23,640 --> 00:02:26,640
holds so many charges.
It could be damaged.

48
00:02:26,640 --> 00:02:28,950
There's a lot of possibilities with that.

49
00:02:28,950 --> 00:02:33,950
And this port is actually
soldered onto the board.

50
00:02:34,140 --> 00:02:36,773
So if this port was to
go bad, you'd have to

51
00:02:36,773 --> 00:02:39,870
re-solder a new one or
replace the whole board

52
00:02:39,870 --> 00:02:42,330
which you know, can be a bit difficult.

53
00:02:42,330 --> 00:02:43,560
Usually that doesn't go bad.

54
00:02:43,560 --> 00:02:46,410
So that's not usually a problem.

55
00:02:46,410 --> 00:02:51,213
What's more likely to go
bad is the DC in-jack.

56
00:02:55,140 --> 00:02:59,850
And that's right over
here, this guy right here.

57
00:02:59,850 --> 00:03:01,920
And that's because when
people connect to the

58
00:03:01,920 --> 00:03:05,820
DC in-jack quite often, they'll, they

59
00:03:05,820 --> 00:03:09,270
might wiggle the connection
or jiggle it in there.

60
00:03:09,270 --> 00:03:11,460
And you know, it could
cause damage over time.

61
00:03:11,460 --> 00:03:14,259
In the past, this DC in-jack was

62
00:03:14,259 --> 00:03:16,470
soldered to the motherboard.

63
00:03:16,470 --> 00:03:17,303
And if that's the case

64
00:03:17,303 --> 00:03:19,410
it could be a bit of a difficult fix.

65
00:03:19,410 --> 00:03:20,700
But in this case this guy

66
00:03:20,700 --> 00:03:23,730
just pulls right out and
just has a connector.

67
00:03:23,730 --> 00:03:25,720
So we can actually take that guy

68
00:03:26,910 --> 00:03:29,190
and just pull him straight out of there.

69
00:03:29,190 --> 00:03:31,720
And then he's just got a connector here

70
00:03:33,540 --> 00:03:35,140
and you can pull that right out.

71
00:03:36,150 --> 00:03:39,780
And so you see it's just
a typical 4-pin connector

72
00:03:39,780 --> 00:03:42,240
and you could swap out
the whole DC in-jack.

73
00:03:42,240 --> 00:03:44,910
This is part number ST5034.

74
00:03:44,910 --> 00:03:46,980
So that's the guy I would use for that.

75
00:03:46,980 --> 00:03:48,663
Real easy change out.

76
00:03:50,160 --> 00:03:52,680
And that's a good thing for it Toshiba.

77
00:03:52,680 --> 00:03:54,360
Good thing for the laptop industry

78
00:03:54,360 --> 00:03:57,540
in general that it's not
soldered onto the board

79
00:03:57,540 --> 00:04:01,140
because they do get
damaged fairly frequently

80
00:04:01,140 --> 00:04:03,930
just because of the
wiggling of the jack, where

81
00:04:03,930 --> 00:04:06,439
maybe someone leaves
the jack plugged in ...

82
00:04:06,439 --> 00:04:08,580
the power brick plugged into the laptop

83
00:04:08,580 --> 00:04:10,710
and then puts it in a laptop bag.

84
00:04:10,710 --> 00:04:12,210
And it goes on transit or goes

85
00:04:12,210 --> 00:04:14,310
on a plane and who knows what happens.

86
00:04:14,310 --> 00:04:17,340
And it shifts around in
there and damages the plug.

87
00:04:17,340 --> 00:04:19,380
And sometimes these
just go bad in general.

88
00:04:19,380 --> 00:04:21,633
So easy repair for that.

89
00:04:22,830 --> 00:04:25,800
So there's another portion of the power

90
00:04:25,800 --> 00:04:28,748
and I've turned the laptop
90 degrees clockwise

91
00:04:28,748 --> 00:04:31,380
and we're looking at the corner here.

92
00:04:31,380 --> 00:04:33,810
This is where the power
button is underneath.

93
00:04:33,810 --> 00:04:36,668
If the power button was
to fail, all you'd need to

94
00:04:36,668 --> 00:04:40,360
do is disconnect this
little connector here

95
00:04:46,710 --> 00:04:50,490
and then remove this
little tiny circuit board.

96
00:04:50,490 --> 00:04:53,140
That's where the power button is right

97
00:04:53,140 --> 00:04:54,180
underneath this connector.

98
00:04:54,180 --> 00:04:57,270
And there's a little a little sticker here

99
00:04:57,270 --> 00:05:00,090
that you can remove and
then a screw to take off.

100
00:05:00,090 --> 00:05:03,150
And that's basically it you'll
get the replacement part

101
00:05:03,150 --> 00:05:06,990
for that and you can get a
replacement button as well.

102
00:05:06,990 --> 00:05:09,240
Sometimes they're sold together as a kit.

103
00:05:09,240 --> 00:05:11,610
So that's another thing that
might fail the power button.

104
00:05:11,610 --> 00:05:13,650
Sometimes people hit it too hard

105
00:05:13,650 --> 00:05:17,250
or it just fails over time
due to usage or what have you.

106
00:05:17,250 --> 00:05:19,350
So that's pretty easy fix also.

107
00:05:19,350 --> 00:05:20,970
All these fixes though you know,

108
00:05:20,970 --> 00:05:23,970
they require opening up
that case at a laptop.

109
00:05:23,970 --> 00:05:27,910
So again, if you have a warranty,
make sure you check first

110
00:05:27,910 --> 00:05:30,750
if you open a case, you're
gonna void that warranty.

111
00:05:30,750 --> 00:05:31,713
If you do have one.

112
00:05:32,580 --> 00:05:34,230
And so that's pretty much
everything you need to know

113
00:05:34,230 --> 00:05:36,930
for power for the exams,
you've got your power button

114
00:05:36,930 --> 00:05:39,600
you've got your power brick,
you've got your battery

115
00:05:39,600 --> 00:05:41,610
you've got your battery connection.

116
00:05:41,610 --> 00:05:44,310
And you've got that DC in-jack as well.

117
00:05:44,310 --> 00:05:45,960
Very important.

118
00:05:45,960 --> 00:05:46,890
The last thing I wanna talk

119
00:05:46,890 --> 00:05:48,210
about real quick was the speakers.

120
00:05:48,210 --> 00:05:50,300
Sometimes the speakers will fail

121
00:05:50,300 --> 00:05:53,428
not quite as often anymore,
but on a typical laptop

122
00:05:53,428 --> 00:05:55,890
like this, it's considered a stereo system

123
00:05:55,890 --> 00:05:59,310
which means it has two
speakers and they're

124
00:05:59,310 --> 00:06:01,230
in little housings and

125
00:06:01,230 --> 00:06:03,100
you can pull those housings right off

126
00:06:07,860 --> 00:06:08,970
and you can see, there you go.

127
00:06:08,970 --> 00:06:10,650
There's your speaker.

128
00:06:10,650 --> 00:06:11,483
That's right.

129
00:06:11,483 --> 00:06:12,316
That's a speaker.

130
00:06:12,316 --> 00:06:14,922
And that's why stuff sounds pretty tinny

131
00:06:14,922 --> 00:06:18,330
on most laptops because the speaker's tiny

132
00:06:18,330 --> 00:06:23,330
but that just connects
with two standoff screws.

133
00:06:23,670 --> 00:06:25,830
And the other one here is the same thing.

134
00:06:25,830 --> 00:06:27,750
It's got two standoff screws as well

135
00:06:27,750 --> 00:06:31,020
and both of these connect
to this connector.

136
00:06:31,020 --> 00:06:32,460
So if one speaker fails

137
00:06:32,460 --> 00:06:35,713
really you're gonna have to
replace both of them as a kit.

138
00:06:35,713 --> 00:06:37,770
You could try to solder

139
00:06:37,770 --> 00:06:39,660
on two wires onto the connector,

140
00:06:39,660 --> 00:06:40,680
but I wouldn't recommend it.

141
00:06:40,680 --> 00:06:44,121
It's gonna come as a kit
with both speakers and this

142
00:06:44,121 --> 00:06:48,270
this connector here, which
will plug back into this.

143
00:06:48,270 --> 00:06:50,010
So that's a pretty easy fix too.

144
00:06:50,010 --> 00:06:51,090
You really just pull these

145
00:06:51,090 --> 00:06:54,968
off, pull both off and replace them.

146
00:06:54,968 --> 00:06:57,930
Make sure that you're doing
it for the exact laptop though

147
00:06:57,930 --> 00:07:01,953
because you know, this
is, I believe an E45.

148
00:07:03,300 --> 00:07:06,090
And even the difference between this model

149
00:07:06,090 --> 00:07:10,440
the E45 and the E55 has a
different design of speakers.

150
00:07:10,440 --> 00:07:11,910
So, you know you gotta make sure

151
00:07:11,910 --> 00:07:14,550
you're getting it for the exact model.

152
00:07:14,550 --> 00:07:16,530
And so again, if the
speakers fail, that's it

153
00:07:16,530 --> 00:07:20,670
you're gonna replace
both speaker housings and

154
00:07:20,670 --> 00:07:22,050
those connected to the plug.

155
00:07:22,050 --> 00:07:23,490
Here, there's a little piece of tape.

156
00:07:23,490 --> 00:07:27,120
that's just covering up this
and holding the wire down.

157
00:07:27,120 --> 00:07:30,120
So that's the only reason for that.

158
00:07:30,120 --> 00:07:32,250
And so that's basically
it, that's your power

159
00:07:32,250 --> 00:07:35,280
and your speakers pretty
easy fixes for most of these

160
00:07:35,280 --> 00:07:37,320
the main key here is compatibility.

161
00:07:37,320 --> 00:07:40,560
Remember to use products
that come from the

162
00:07:40,560 --> 00:07:44,370
manufacturer and that they're
the right model, excuse me

163
00:07:44,370 --> 00:07:49,263
the right part number for that
particular model of laptop.
