Laptop
I made a laptop using Fusion 360.
Supplies
Fusion 360 is needed.
Laptop Base
First, sketch out the base of the laptop; we are going to extrude it. Also round the corners just for good measure. Extrude the base.
Sink the Keyboard Base
If the laptop that you want to create has a keyboard on a concave base like mine, you should use the extruded cut tool to sink part of the keyboard like so. Fillet the edges.
Create the Sketch of the Keys
Create sketch on the sunken surface for the keyboard. Using the dimensions of a key, create a rectangle, and then round the corners. After which, create an offset of the sketch outwards by a reasonable distance. This is to later use that outer ring to create an extruded cut downward around the keys and simulate the aesthetics of a laptop keyboard. Sadly, I'm not an engineer or an expert at 3d design, so that's the best I can do to mimic a laptop keyboard.
Creating the Key
Extrude the inner sketch of the key to a reasonable distance (For me, I simply extruded the keys to the height of the key from the sunken base of the keyboard to the original height). Then, extrude cut the outer sketch surface downwards to a reasonable distance (the distance doesn't really matter as long as you don't cut a hole through the laptop base or make a hole that is obviously way too shallow).
Creating the Keys
Now, repeat step 4 until you have completed the whole keyboard. Good luck... That's all I can say. (Tip: You can use the rectangular pattern tool to copy and paste the keys)
Creating the Power Button
Sketch out a circle above the keys. Using the same method used previously to simulate a button kind of feel, offset the circle outwards for a reasonable distance, and then extrude cut downwards.
Creating the Touchpad
Sketch a rectangle the dimensions of the touchpad, and then create another rectangle that's split into 2 below the first one. Use the fillet tool to round the corners. Then, sink the top rectangle to a reasonably short distance; this is to emphasize its existence. After which, again utilize the button simulating technique, offset both the outer sides, and the line dividing the bottom square (since they're 2 different buttons). Extrude cut downwards.
Creating the Screen Part 1
Sketch out 2 squares to cut out on the base, like so. This is the intersection of the base to the screen, and should be the same size, shape, and position as each other. Pro tip: Use the mirror tool. Use the extrude tool to cut out the sketch area.
Creating the Screen Part 2: Sketch
Now, Sketch out a base for the screen, like so. First, sketch out a circle. The circle is the part that's only there for aesthetics; it is to simulate a twistable axis for the screen to close. Then, create 2 lines coming out of it. If you want to make it perfect, you can first sketch a construction line through the circle. (If you simply create 2 lines on the circle straight up, chances are that the bottom line will overlap with the circle, which annoys me, as someone with OCD. If not, you can go ahead and skip this entire paragraph) After which create a line with the angle you want on the side. Using the tangent tool, connect the line with the bottom end of the line you had previously sketched out. Trim the end that pokes out below and use the Dimensions tool to manipulate the length of the line. Follow the same procedures with the top line, but simply create the line on the top end of the construction line.
Creating the Screen Part 3: Axis
Extrude the circle to the other side of that space. This is the Axis to the screen. Also, use the mirror tool to do the exact same thing on the other side.
Creating the Screen Part 4: the Screen
Now, extrude the sketch that's actually the screen, to the same distance as the axis. Next, create a sketch with a point spline that looks like it's rounded. This is to divide the top part to the bottom part, as we need to extrude the top part of the screen side to the width of the whole laptop. This is to avoid collision between the screen and the base. Again, use the mirror tool to do the exact same thing on the other side.
Creating the Screen Part 5: Also the Screen
Extrude the top part of the side profile of the half-completed screen to the side profile of the laptop base. Then, extrude that left-most profile of the screen, to the right most profile of the laptop base. This will complete the screen, or at least the base of it.
Creating the Screen Part 6: the Actual Screen
Use the extruded cut tool to sink part of the screen to a reasonable depth. This is the actual screen.
Finishing Touches
We are finished. You can now do some finishing touches such as rounding the corners or adding some appearances. Unfortunately for me, I couldn't completely build a one-to-one model of a laptop, since I don't have enough time, and lack the diligence. But I'm still proud of this build. As a beginner who's only done 3D design for about a month, I think this is pretty decent.
