and this, and this module will look at
other things to consider when discussing laptops and portable computers.
Laptops usually have a numerous, uh, number of special function keys involved to perform common tasks such as changing the volumes.
They're not always gonna be the same key on every computer. They usually have some kind of emblem. That's well, they'll tip you off to what that function does that usually located along with the number keys on the top row and then you. Most laptops also have a button called the Function Button, or FN. So
activate those keys. You hold the function button
and the appropriate keel on the top. So it's not always gonna be the same number, but
well, usually definitely have some kind of symbol like like the one shown on the screen here for audio. They also happen for the volumes. There might be a plus and minus for the volume. Sometimes it might also be a hard switch. Also, sometimes they have extra buttons. They're located along the top of the topper side of the laptop that allow you to perform
these special functions.
But most common ones are ones for audio
to control the volume mute it.
They also used to be a bun for activating the external
VJ or Devi I pour on the laptop. All laptops will have some kind of output for video
that could very from s video Devi I see my
or typical V g A. Uh, this is used usually to plug it into a TV or a projector such as this,
so you can usually do this through the software. But it's usually easier, and they all have a button for it, where you can do it through the keyboard as a quick shortcut.
Again, I'll use the function key, but we'll always be the same function key on every PC. Usually have a little emblem on it that looks like, ah, square two squares next to each other. And that would be the one for activating external.
Sometimes when you plug in the V G a cable, if it's already plugged into a projector or activate automatically on its own.
So what happened is
depending on your specific operating system. When you plug it in, you either go into extended display or duplicate display.
Extended display is where functions as dual monitor. So if I plug in a laptop
to a projector. I still have their the operators to independent screen. So my laptops one display. So if I open something up and I have that window on my main display, it's not going to show on the projector. But if I move that window over to the other onto the side of the screen, owns the other display, I'll show up on the projector and not on my laptop anymore.
That's called extend display. The other. The other mode is duplicate displays
or marrying or cloning, which the laptop what's shown on the laptop will be the same thing that shone on the external display or
Now, when using the quickies, you can usually scroll through these options by repeatedly hitting me function in the appropriate key. So let's say that it's the F two key. We function F to the first time it gives us extended displays. Next time we hit, it may give us duplicate displays.
Another. Next time I hit it, it might turn off my LCD display
and just have the
projector on. That's another option where you're only output is the projector or your
external out, and it turns off this display on your LCD on the fourth option is
turning off the
external display again and only showing it on the LCD. So every time you hit, it'll cycle through. Those four will go not necessarily in that order, but
extend to display it again. Duplicate, display another one. Turn off the LCD and just have it on the external display and then return back to your original status, where
you're only on the LCD
windows. You can also use the Windows Key plus P to do that same function if you don't have a laptop to do it, if you don't have a special key on the laptop.
I also noticed that sometimes when users air
trying to connect to projector, it's just too high of a resolution.
So they're going like 1900 by whatever. It's not gonna be ableto even if you try to send contents. Sometimes you'll find that you'll get a message pop up depending on the VTC.
So resolution, sometimes key in the refresh rate, sometimes could be an issue, too. So that's That's a good point. So it works both ways, actually, as faras the resolution goes, so sometimes the native resolution of the projector, which is the resolution that it displays the best at were a large TV
your laptop might even part might not be powerful enough to drive that larger display so it might not look writes. That could be a problem. Sometimes that can be fixed by one. Turning off the
L. C D display and having it just go external, because when you're running both at the same time, your graphics card is having to do extra work.
And so some graphics cards are not powerful enough to drive to displays at the same time, because think about it's driving your LCD display and it's driving and output to a large green monitor.
It's a lot of times will probably be fixed by disabling the on screen monitor the LCD monitor and just having an output to your external source.
I'm not saying now. Always work. Sometimes that's still if you're going to a really big display and you're using a netbook, you're still not gonna have enough power
to drive a large or an older laptops Not gonna drive Ah,
1920 by 10 80
but the others also true where sometimes your monitors trying to push out a higher resolution
than the TV or the native resolution of your external source. I need to make sure that you might have to scale it back,
especially if you're doing cloning. So will happen is we'll look it on the screen?
But it'll look really oversized on your LCD monitor because you had to bring down the resolution to match what's optimal for your projector or
Good point, Thank you.
Also, there's commonly some kind of switch to turn on off wireless.
This one's more commonly used one because
airplane mode too common.
necessity. You're traveling on airplane. You need turn off your radios, but you want to use your laptop. You can trough the WiFi quickly. Using the function in the appropriate CHEOL usually have some kind of image similar to this
indicate wireless. Usually you'll cycle through it. It'll turn off,
we'll turn off wireless, and the next time you do a turnoff Bluetooth. Next time you do, it'll turn off wireless and Bluetooth,
and the next one you do, we'll turn all back on. It would be usually some kind of cycle, and when you do that, you're gonna pop up in your windows on your display, saying which has been turned on and off
sometimes. Also be a hard switch.
I know my demo laptop. I have a hard switch in the front and flip the switch and it turns it off. I don't have to push. A button
could also be done through the software itself. That's a little that's a little
more work, as opposed to just a quick button
again. Either hard bun or sometimes it'll be. It'll be a function key and
various option on the number row,
which will vary by laptop
brightness, controls this another common one
for a couple reasons. Sometimes you're working in dark area. You know what the miners bright.
It's a lot of work to go into just brightness through the Windows Control panel. So usually will be, Ah, hardwire key such as this.
Or it will be one of the soft function keys where you couldn't function and another key on the keyboard, and I'll usually have a plus or minus. We can go up in brightness or down and brightness.
Another reason to lower the brightness is, well, the bride of the screen.
The more pirates taking us a battery life
can lower the brightness down.
And speaking of power saving, that's just on a side note. So one of the things with laptops is
they're designed to be.
They're designed to be energy efficient. You wanna have got to be able to use them for a long time without plugging in power. So one of the popular settings and Windows is they have a par control option where you can say
what is plugged in a lot to run a full part, full brightness and when it's on battery
automatically lower the brightness and what that also do. It's called par saving mode.
It'll also throttle back the CPU, so the CP won't run
at smack from speed. It'll run out slower speed, so you may see a degradation in performance and your everyday use of the laptop.
But the battery's gonna last a lot longer. So So it sze. So we're slower, but still better than not having any power at all. So lowering the brightness darling back and then on top of that, you know, turning off things like WiFi. The more things you turn off,
the longer the power is gonna run the longer the barriers in the last.
So there's some special attentions to pay two things. Spay pay special attention to when
talking about laptop computers. So
when you're storing it, you're gonna start for a long time. Is a good idea to remove the battery
for extended storage.
They get banged around a lot. So if you don't have one of these tough books or something that's designed to be a rugged laptop, make sure you get some kind of case.
If it's, ah, you're gonna be trying a lot might want to have a hard case for it, but they could get dinged up pretty easily. And if they get dropped in the 90 case, uh,
you can easily break stuff inside them,
especially since you're usually carry it with you get knocked around, throwing it in cars and stuff. So it's definitely worth the investment. If you travel a lot to get a quality case for it,
you shouldn't keep CDs in the drive. When you're traveling, make sure
you don't have any Dunga. Lt's like a USB flash drive sticking out. Be aware that and do their size. They're really have a high potential for theft
so again. So you something like one of these laptop steel cables that you can use to lock it to a Secure it to a desk,
Take it with you Everywhere you go. If you're at a restaurant, don't leave it where you can see in a car. Well, speaking of cars,
don't leave it in a car for too long. Especially on a hot day.
You could melt, especially if it's, you know, right in the front with the windows are they're very susceptible toe heat. So he is very bad for computer. So
on a hot day, don't leave it in the car or in a window
if we have to ship it.
Sure, you remove all of these components like optical like sea robins and the battery. Make sure you pack it well. Use a lot of bubble wrap. Makes you are
you definitely want to put a
tracking number on and probably get the warranty coverage
for the shipping in case something goes wrong
most often. This will happen when you need to return it for repairs. The manufacturer most of them will
have you ship it on there on your own dime and they'll give you. Ah, address.
I know a lot of times also is part of the return process. Tell you exactly how they expected to be shipped. They'll say Use bubble wrap and the size box.
And one of the most common things with laptops is it's a tripping hazard because we have a lot of cables coming out of it. Especially
the power cable. That's the most common one.
Try to plug it in where it's not gonna be in the direct path of common traffic. I know I've tripped over my fair share off
power chords know only that dangerous for people chip over.
Also, if you pull out just right to pull the whole laptop off the desk with you or it could pull out and break the connector part on the laptop itself, where the power supply connection.
If that breaks, you're gonna have a bad time.
The other cases arm or if the park able the biggest one now with WiFi, we don't see the network cables as much of ah issue.
So going back to talk about some of these common controls, like brightness,
I just want to show an example of some of them on my demo laptop.
So in this one, I've got
an actual hard volume here That's not too common anymore, but it's an actual little
plastic wheel action raise and lower the volume
most of time. Now it's gonna be a soft button on the keyboard,
but this one actually has a
no school wheel.
Then right here is a switch
I can flip to turn on off wireless.
That's not as common anymore, either. Most time that's gonna be soft that
with the advent of laptops and mobile device with
portable devices such as tablets and phones, everyone's used to having everything being a soft button and not mechanical switch so and mechanical switches cost a little more Issy. You're seeing less and less of the mechanical type switches on laptops beside the power. But
look at the top. So in this case, So I took this out earlier, but you could see so we have. We have a couple of buttons that are not on the keyboard itself that are that are actual hard buttons.
So these kind of shortcut keys in this case I have the par. But in here,
this one's a shortcut to open a Web browser.
Short cut, open my media player
and then, you know, play pause, Stop for back. Other ones may have buttons on here similar to this that will do your brightness or your wife. I
Some of them have ones that ejector see Rahm Drive for you other kind of various function that would commonly be seen on the keyboard.
We're going to see these,
I think better.
So on this keyboard along the top here there's
very subtly There's blue
icon there below the F keys. And these are the special function keys that hit the function key right here. And I pushed one of these will perform that function like I discussed before. So in this case, escape has a little picture of speakers on. And if I hit that,
I hit that that will mute the sound or a mute the sound. So if I wanna, you know, I've got a phone call and I want a mute real quick, I can't hold function
and that button and l'm you know, and I don't have to go messing around in the
in the control panel or in the settings on the U. S. Itself
on this one. This is a picture of a padlock. I hit that ill
locked PC for right away.
A little known. Ah, not a lot of people know this, but another way to lock it right from windows as you do the windows Ki l that'll lock your screen right away. Also,
uh, on this one, the F five shows a little picture of the LCD and a picture. And in a square that was the one that let me rotate between
extended mode for the external display or clone mode or just turning the external display on this will rotate through my external display options.
This one we have the low brightness symbol with the down arrow in a brightness symbol with the up arrow, those air raised the brightness lower the brightness. Another common place to see the brightness or volume control would be on the arrow keys.
So there'll be a little sub icon on the arrow keys. And so maybe lowering the brightness be function left and function right in the lower. The volume would be function down,
function up. That's another common location on keyboards.
On this one. I also still have an option to disable the WiFi on the function keys besides the button on the
on the front
in this case,
because this ah, hard. But on this laptop, the hard button, the hearts which will take precedence over any other settings
in the software because it's a hard switch
and this will allow me disable the trackpad
right here. Now, this is handy. If you know you're gonna be using external mouse a lot,
you can disable the trackpad, and this is handy because if you're doing a lot of typing,
you have a stroll mouths. That happens a lot where you start typing office and you're typing in the middle of the screen because your palm accidentally hit
That's a very handy feature.
