WEBVTT 1 00:00:00.270 --> 00:00:02.220 In this lesson, I'm going to show you how to replace 2 00:00:02.220 --> 00:00:04.530 an expansion card inside of a laptop. 3 00:00:04.530 --> 00:00:07.860 Now the laptop I'm going to be using is a Lenovo Y540, 4 00:00:07.860 --> 00:00:10.712 and this one uses a mini PCIe connector 5 00:00:10.712 --> 00:00:13.980 to be able to use a Wi-Fi card embedded into this laptop. 6 00:00:13.980 --> 00:00:16.530 Now your laptop will place this at a different location, 7 00:00:16.530 --> 00:00:19.200 but the process is essentially the same to replace it. 8 00:00:19.200 --> 00:00:20.130 On this laptop, 9 00:00:20.130 --> 00:00:21.930 this wireless card is located right here 10 00:00:21.930 --> 00:00:23.340 so it's pretty easy to get to. 11 00:00:23.340 --> 00:00:25.950 And on your laptop, it may be in a different location. 12 00:00:25.950 --> 00:00:28.380 So check your manual to figure out the location of yours 13 00:00:28.380 --> 00:00:30.990 and figure out how you can update it on your system. 14 00:00:30.990 --> 00:00:31.950 Now on mine, 15 00:00:31.950 --> 00:00:34.530 I'm simply going to peel back this little plastic shield 16 00:00:34.530 --> 00:00:35.790 so it's out of the way, 17 00:00:35.790 --> 00:00:39.000 and you'll notice we have a mini PCIe connector right here. 18 00:00:39.000 --> 00:00:40.683 This is a small little expansion card 19 00:00:40.683 --> 00:00:42.750 that is going to be serving for our Wi-Fi 20 00:00:42.750 --> 00:00:44.310 or wireless networking. 21 00:00:44.310 --> 00:00:45.510 And you'll notice there is a black 22 00:00:45.510 --> 00:00:47.580 and gray cable coming out of the side here, 23 00:00:47.580 --> 00:00:49.860 and those are actually going to be my antenna. 24 00:00:49.860 --> 00:00:53.190 So the first thing I need to do is disconnect those antenna 25 00:00:53.190 --> 00:00:54.900 from this laptop. 26 00:00:54.900 --> 00:00:57.210 To do that, I'm simply going to grab a pair of tweezers. 27 00:00:57.210 --> 00:00:59.820 I'm going to grab onto that antenna connector and pull upward 28 00:00:59.820 --> 00:01:01.440 because it is a button type connector 29 00:01:01.440 --> 00:01:03.450 that simply pushes with pressure to connect 30 00:01:03.450 --> 00:01:05.343 or pulls with pressure to disconnect. 31 00:01:07.530 --> 00:01:09.060 Now that I've gotten both of those off, 32 00:01:09.060 --> 00:01:12.060 I'm just going to push them out of the way with my fingers 33 00:01:12.060 --> 00:01:13.410 and push them to the side. 34 00:01:13.410 --> 00:01:15.690 And now you'll notice this card is being held in 35 00:01:15.690 --> 00:01:18.240 with a single screw right here. 36 00:01:18.240 --> 00:01:20.640 To get that out, I'll simply use my screwdriver. 37 00:01:24.600 --> 00:01:26.520 And as I do that, you may notice 38 00:01:26.520 --> 00:01:29.520 that this card is starting to move its way up. 39 00:01:29.520 --> 00:01:31.080 When you have a mini PCIe card 40 00:01:31.080 --> 00:01:32.940 and it's screwed down, it sits like this. 41 00:01:32.940 --> 00:01:34.380 But as you release that screw, 42 00:01:34.380 --> 00:01:35.610 it's going to start pushing its way up 43 00:01:35.610 --> 00:01:37.080 almost to a 45 degree angle 44 00:01:37.080 --> 00:01:39.300 because that is the way it gets inserted and taken in 45 00:01:39.300 --> 00:01:42.090 or out of the slot when you're applying a new card. 46 00:01:42.090 --> 00:01:44.460 So now you'll see that it's up at a 45 degree angle, 47 00:01:44.460 --> 00:01:46.260 I can simply grab it with my fingers 48 00:01:46.260 --> 00:01:48.390 and pull and it comes right out. 49 00:01:48.390 --> 00:01:50.520 And now I have that expansion card. 50 00:01:50.520 --> 00:01:51.600 Now if I wanted to replace this 51 00:01:51.600 --> 00:01:53.067 because this was a wireless end card 52 00:01:53.067 --> 00:01:56.610 and I wanted a new wireless AC or wireless AX card, 53 00:01:56.610 --> 00:01:58.200 I could simply buy one that's going to fit 54 00:01:58.200 --> 00:02:00.120 into this mini PCIe slot 55 00:02:00.120 --> 00:02:03.450 and then take it, insert it in at a 45 degree angle, 56 00:02:03.450 --> 00:02:05.520 making sure that it's sitting in the right way, 57 00:02:05.520 --> 00:02:06.660 giving it a little pressure, 58 00:02:06.660 --> 00:02:09.120 and then I will sit it down with my finger, 59 00:02:09.120 --> 00:02:10.410 grabbing it with my thumb, 60 00:02:10.410 --> 00:02:12.480 I'm going to grab the screw, 61 00:02:12.480 --> 00:02:15.363 and I'm going to put that screw right back into place. 62 00:02:17.580 --> 00:02:18.540 And there we go, 63 00:02:18.540 --> 00:02:20.610 that is now screwed back in. 64 00:02:20.610 --> 00:02:23.790 Now this wireless card isn't going to work great just yet. 65 00:02:23.790 --> 00:02:24.750 And the reason for that is, 66 00:02:24.750 --> 00:02:26.790 I haven't reconnected my antennas. 67 00:02:26.790 --> 00:02:29.430 When you're dealing with a wireless card or a cellular card, 68 00:02:29.430 --> 00:02:31.710 the antenna is a very important thing. 69 00:02:31.710 --> 00:02:33.420 If you don't connect an antenna, 70 00:02:33.420 --> 00:02:35.640 this card will only be able to go a few feet 71 00:02:35.640 --> 00:02:38.880 with wireless signal instead of being able to go 30, 72 00:02:38.880 --> 00:02:41.040 50, or 100 feet like it should. 73 00:02:41.040 --> 00:02:43.740 And so I want to make sure those antennas are connected again. 74 00:02:43.740 --> 00:02:45.030 Now, if you remember correctly, 75 00:02:45.030 --> 00:02:47.940 we had the black antenna here and the gray antenna here. 76 00:02:47.940 --> 00:02:49.020 And on this card, 77 00:02:49.020 --> 00:02:51.840 it actually labels that using a little black arrow here 78 00:02:51.840 --> 00:02:53.550 and a little white arrow here 79 00:02:53.550 --> 00:02:55.680 so I'm going to place the gray one first 80 00:02:55.680 --> 00:02:56.820 'cause it's closest to me, 81 00:02:56.820 --> 00:02:58.530 and then I'll put the black one in. 82 00:02:58.530 --> 00:03:00.210 You can try do this with your fingers, 83 00:03:00.210 --> 00:03:01.290 but if you have trouble, 84 00:03:01.290 --> 00:03:03.660 you can always use one of those tweezers 85 00:03:03.660 --> 00:03:04.980 to help push it in place. 86 00:03:04.980 --> 00:03:07.830 Simply line it up, push down on it with your thumb, 87 00:03:07.830 --> 00:03:10.020 and it should snap into place. 88 00:03:10.020 --> 00:03:12.420 And if it doesn't, you might want to use tweezers. 89 00:03:25.800 --> 00:03:27.930 In my case, I'm going to use my tweezers 90 00:03:27.930 --> 00:03:30.420 and my pry bar to apply the pressure 91 00:03:30.420 --> 00:03:31.970 and make sure that is in place. 92 00:03:32.820 --> 00:03:35.460 Now always be careful when working with these antennas 93 00:03:35.460 --> 00:03:37.200 because if you do it incorrectly 94 00:03:37.200 --> 00:03:38.940 and you just yank on the cable, 95 00:03:38.940 --> 00:03:41.400 you can actually pull the antenna cable out 96 00:03:41.400 --> 00:03:43.860 instead of pulling the button off of the connector. 97 00:03:43.860 --> 00:03:45.240 And that will damage the antenna, 98 00:03:45.240 --> 00:03:47.943 and your Wi-Fi will no longer work in this laptop. 99 00:03:49.170 --> 00:03:51.753 Next, I'm going to grab that black one, line it up, 100 00:03:56.009 --> 00:03:58.840 and then push it down with that pry bar. 101 00:04:04.890 --> 00:04:08.460 Okay, now I'm giving a little tug on it with my tweezers 102 00:04:08.460 --> 00:04:10.230 and I can see that they are in place 103 00:04:10.230 --> 00:04:12.510 and they're not moving as shown here. 104 00:04:12.510 --> 00:04:14.520 If I pull on them a little, they're not moving anywhere. 105 00:04:14.520 --> 00:04:15.810 They're just sliding back and forth 106 00:04:15.810 --> 00:04:16.980 like they're supposed to. 107 00:04:16.980 --> 00:04:19.080 And then there is this piece of plastic, 108 00:04:19.080 --> 00:04:20.760 it's just a little bit of tape to hold them down 109 00:04:20.760 --> 00:04:22.500 and keep it out of the way of other components, 110 00:04:22.500 --> 00:04:24.210 so I'll put that back. 111 00:04:24.210 --> 00:04:26.610 So now that we've installed the wireless card, 112 00:04:26.610 --> 00:04:28.380 you've seen how to take out a card 113 00:04:28.380 --> 00:04:32.280 and put in a new card using your mini PCIe expansion slot. 114 00:04:32.280 --> 00:04:33.480 Another thing to note when it comes 115 00:04:33.480 --> 00:04:36.750 to Wi-Fi cards is their antennas are going to be wrapped around 116 00:04:36.750 --> 00:04:38.730 the external part of your case. 117 00:04:38.730 --> 00:04:39.690 You'll notice here, 118 00:04:39.690 --> 00:04:41.550 those cables started here on the card, 119 00:04:41.550 --> 00:04:43.530 they went up, and then they curve backwards, 120 00:04:43.530 --> 00:04:46.110 and we could see those cables going all the way down here, 121 00:04:46.110 --> 00:04:47.910 and they're actually going to go under the battery 122 00:04:47.910 --> 00:04:50.010 and around the entire case. 123 00:04:50.010 --> 00:04:52.020 So remember, when installing a Wi-Fi card, 124 00:04:52.020 --> 00:04:54.120 always make sure those antennas are connected 125 00:04:54.120 --> 00:04:56.550 and that you don't damage these cables running out 126 00:04:56.550 --> 00:04:58.290 as they go along the rest of the perimeter 127 00:04:58.290 --> 00:05:01.290 as you're doing other components or upgrades to your laptop.
