Video Description

Troubleshooting Laptop Issues Part 3 Some of the last topics we will discuss include hardware issues such as bad wireless card or card connectivity issues because the MAC address is wrong or other wireless access point setting is incorrect. Next we look at Bluetooth and how it works, and whey the simplest issue is just confirming its both physically on the device as well as in the Windows OS. And finally we examine how to resolve physical hardware issues such as not connecting to an external monitor, and performing disassembly repairs assuring we've installed new components correctly, replaced all required parts, cables, used the appropriate tools without damaging parts or components, haven't broken connectors and have correctly labeled and accounted for every component during the disassembly-reassembly process.

So what are some of the possible causes? We should check if one of our symptoms is. We have no network connectivity, no wireless connectivity. Well, we may have a bad wireless. Nick, the our wireless card inside of our computer acts much like a wired network interface card. And then it has to send and receive our data at that
00:23
at a level that we can push it out.
00:26
Now. If that wireless car has gone bad, maybe it's Mel. It's incorrectly formatted. We've tried reach reinstalling the drivers, and it just doesn't detect that we have a wireless card. Then we may need to have that wireless card replaced.
00:42
We may also have our wireless switch toggle to the off position. Many of our laptops have manual wireless toggles, such as a physical switch on the side or the bottom of the laptop, or maybe a function key pressed with a wireless ah wireless indicator. If this is toggled off,
01:00
none of our internal computer settings can actually change that. So we need to make sure that that toggle is in the on position.
01:06
Then we have the adaptors turned off. Now this is a setting inside of our computer when we go to our network settings and then adapter settings are our adapter in settings in our computer may have our wireless car disabled, so we may want to make sure that we go to our network settings adapter settings
01:23
and enable that and make sure that it's enabled in order to see that wireless connectivity.
01:27
And then we may have our wireless access point settings may be incorrect or wireless access point may be off. It may have the s s I d broadcast off, so we need to manually set the s s i d. It may have filtering on and they have Mac address filtering and our Mac addresses and in that list, or we may have improperly entered it in that less list.
01:48
It may have some access control lists
01:49
or we may have entered of invalid key. So we want to check all of our local settings as well as all of our wireless access point settings and make sure that it's not the wireless access point or settings related to the wireless access point on our computer, such as of the key that is causing that issue with connecting to the wireless.
02:07
Next we have our Bluetooth. Now are Bluetooth. We may not be in range of the device are Bluetooth range is a lot shorter than that of sale wireless range. So we need to make sure that we're within range of the device in order for it to work.
02:21
Our Bluetooth may be turned off on our computer, much like our wireless also has toggle switches are wireless, has an on and off function switch. Our Bluetooth may also have a function switch. Our Bluetooth may also be turned off inside of our windows settings on our laptops. So we want to go in and check
02:38
and make sure that our Bluetooth is toggled on not only physically, but also in the settings and our computer.
02:43
And then, lastly, we may have bad drivers. Just like our wireless card we could have bad drivers on our computer are Bluetooth may also have bad drivers, so we may want to check and see and try uninstalling and reinstalling. Or, if we've recently updated, try rolling back those Bluetooth drivers to see if we can get it working again.
03:01
Now we have we can't ex connect to an external monitor.
03:05
Now Our laptops typically have ports that allow us to connect to an external monitor for an additional monitor display or a television or a projector. And sometimes connecting to these external monitors don't work properly. We may need additional drivers, depending on the monitor type, depending on the connection type
03:23
we may need to install additional drivers in orderto have that external display display properly.
03:29
So you want to check those additional drivers and, if necessary, get them installed for that particular monitor
03:34
we may have. Incorrect monitor settings are monitor may be looking for a connection on, say, a V G A setting rather than a Devi Devi I or a HD on HD Am I? We're trying to connect to an external television display. We may have our television set, too,
03:53
say the That's the TV mode, the cable box rather than our laptop.
03:58
We also need to check the monitor settings on our computer and make sure that we're not set to laptop monitor only that were set to extend or duplicate on an external monitor. So you want to check those monitor settings and then lastly, we want to make sure that we are checking our cables in our ports.
04:15
We don't want to have a bad cable that has a short in it and connected up. That may be causing our monitor issues.
04:19
Or we may have a bad port on our laptop or on the display monitor itself that is causing us not to be able to connect to that external monitor. And then, of course, we also want to check some of our power related power related causes. Well, we want to make sure that our power is on on the monitor
04:38
and that it is. It's plugged in and it's turned on.
04:42
Now we have our disassembling process. Now this is gonna now are disassembling process for our laptop is gonna greatly ascent, helpless when we put it back together. It's very easy to take a laptop apart if we have the proper tools to do it. We have our screwdrivers, we have our different bits, and we have our tools that allow us to
05:02
pull open our that our laptop keyboard off of our laptop or take a part of the laptop monitor assembly. It's very easy to disassemble a laptop. It's very easy to disassemble a lot of things. The hard part is putting it back together again and having it working. So when we disassemble our laptops or other devices,
05:21
disassembling them properly and disassembling them in an organized manner is going to greatly assist us when we're trying to do reassembly. Now one of our first step is going to be to document our cable and label our cable and screws.
05:35
Now, when we're talking about documenting and labeling our cables and screws, we wanna have some sort of system. If we're especially if we're moving cables and screws to be ableto label and organize our next step, organize our parts as faras where they came from and where they need to go back.
05:53
We may want to take a piece of paper and then, um,
05:57
take a marker and draw in different sections on that piece of paper. So say, if we have a piece of paper here that we've taken a marker and we've just organized out into different boxes,
06:10
and then in these different boxes we made light. We may
06:14
label this box one A screws, and then, as we are taking apart our laptop, we noticed that next two screws a certain link. There's a small inscription on the laptop case one Aye or oui,
06:29
Uh, check our laptop manual and we see that these were screws. Reports of one A screws or certain length screws.
06:34
And we take all of those screws. And when we disassemble our laptop, we just placed them here on our piece of paper on the flat surface. Or if we have a screw organizer in, they even be better for us to place them in there and in order to keep them organized,
06:47
um and then say after we pulled after we remove our after we remove our hard drive, we place our hard drive in one section,
06:58
and then we remove our wireless network interface card, and we place our wireless network interface card in one section. We want to make sure that we're organizing those parts were labeling them. We're not just taking everything apart and sticking, clumping him altogether in a big pile. Because when it comes time to taking this screw and figure out, where does this go?
07:16
How does this go back together here?
07:18
We want to make sure that we know how to do that. We don't just trust on being able to reverse all the steps in our memory. We make sure we actually document how we took everything apart Document where they go back and organize them so that were able to identify them later.
07:32
We also want to refer to ah, the manufacturer. Typically, our laptops will come with disassembly guides. Using these disassembly, guys will be able to recognize the parts, know how to take them out properly and know, Know what order to remove our parts so that we don't damage our laptop and were able to remove the part successfully.
07:50
And then lastly, we want to make sure we use are appropriate tools when, where this assembling our laptop. Just as when were disassembling any any device. We want to make sure that we're not using the improper tools. We're not using makeshift tools in order to do certain jobs. If we're trying to undo a screw, and the screwdriver we have is in a certain size,
08:11
but that better knife work
08:11
well, it's better for us to take the couple minutes it will take for us to go get that proper screwdriver or even go down to the store and get the proper screwdriver than using the improper tools.
08:22
We don't want to crack our cases by trying to pop them open forcefully or pop them open with an improper tool. We don't want to break connectors. We don't wantto strip screws
08:33
because while desktops
08:35
we want to be performing all of these functions as well. Desktops are typically a bit easier to put together just because everything is bigger, everything is more noticeable and it's harder and maybe a little bit harder to actually break or harm different components because they're bigger and they're easier to work with.
08:56
Our laptop components are gonna be a lot smaller.
08:58
They're gonna be a lot more minute and they're gonna be a lot easier to break. So we need to make sure that we're being, ah, lot more careful in documenting and organizing our parts. Well, making sure that we're referring to are manufacturer every time and always making sure that we're using are appropriate tools.
09:13
So thank you for joining us here today on cyber dot i t. Today we talked about troubleshooting and repairing some common laptop issues, such as issues with our display on our laptop issues with our keys issues with our wireless connectivity, and we also talked a little bit about making sure that when we're disassembling our laptop that we're doing so in an organized manner. We're referring to our owner's manual,
09:33
and we're doing it in a way that makes it easier for us to reassemble it later.
09:37
So hopefully you'll be able to take this knowledge and you'll be able to use it and apply it and your trouble shooting of laptops or working on clients or users or even your own laptop. And we hope to see you here next time on cyber Dad, I t.
