    • Let's begin by taking out the disk drive and the battery. To do that, let the side highlighted in pink face towards you.

    • Locate the lock tab of the battery compartment (the one I highlighted in red).

    • Pull the tab in the direction of the blue arrow first.

    • While pulling the lock tab down, pull the lip of the battery compartment (it is located above the lock tab) towards you.

    • The battery tab HAS to open more than 95° in order for the battery to come out. This will be the case for all the things we have to take out from under these kind of tabs, so I recommend dragging the laptop to the edge of the table and opening it all the way there. If you don't do this, you risk accidentally damaging the locking mechanism.

    • If the battery is swollen, it might take some force to pull out. If it's not, it will come out with little to no force. If the tab is missing, damaged or broken and/or you cannot take the battery out, God help you. (you can still continue through the disassembly, but it's strongly suggested that you find a way to take it out before proceeding)

    • Pull on the blue pull tab with very little force. The battery should come out with relative ease.

    • After taking the battery out, you can close the tab back up by slamming it into the chassi. I didn't because we are going to be talking the tab fully out later on anyway.

    • Right next to the battery compartment is this multi-compartment, which we have to open in order to take the disk drive out. To do so, locate the lock tab (highlighted in red)

    • Slide the lock tab to the direction the arrow is pointing in and the cover should pop out. All you have to do now is just open the cover

    • If your Toughbook did not come with a disk drive and this bay is empty, skip the next step.

    • If your Toughbook doesn't have a disk drive, but it has something else, find the way to remove it.

    • Locate the disk drive unlock button and press it so the button comes out.

    • Slide the switch that locks the locking tab in the direction of the blue arrow.

    • Close the computer's lid once the hard drive tab is open

    • The hard drive requires a bit more force than the battery or the disk drive, but it does come out pretty easily too.

    • The grill is caught by the edge farthest from the screw, and the tab can bend easily so I'd recommend taking Julio and prying up from where the screw was.

    • Take the handle out by lifting it up.

    • Beware of the piece shown in the second image. There are four of these pieces, their locations are highlighted in the third image. They are essentially the hinge of the handle, and they like to come out when you least expect them and get lost. I recommend taking them out, and saving them individually. Trust me, you'll thank me.

    • Remove the four screws highlighted here with a JIS #0 screwdriver.

    • CAREFULLY unplug each ribbon by VERY CAREFULLY pulling the black piece of the connector forwards.

    • I won't be taking the track pad, status lights or physical power button out since I see no non-destructive way to do it, and I don't feel like absolutely ruining mine. So I won't be guiding you through that process. But I'll tell you, roughly, how to do it. I DON'T RECOMMEND DOING IT IF YOU DON'T HAVE A SPARE ON HAND.

    • Start by disconnecting those ribbons and un-route them.

    • Then flip the laptop and open it. The thing highlighted in red is actually a giant sticker. Remove it.

    • After you do, find screws, take them out, grab pieces, take them out, it's just what we've been doing all this time.

    • If you managed to do it without any help whatsoever, congratulations, you are now a technician. (This is actually how technicians work most of the time)

    • Time to take the screen apart. Start by removing those screws.

    • Fun fact, I ended up stripping one screw, so I had to drill it out. Those were the slowest most painful 50 seconds of my life.

    • The screen is not glued together, but it has some kind of ancient O-ring that has welded itself between the two metal plates, so carefully pry the screen open.

    • It the last picture you can see the O-ring I'm talking about in the detached back plate.

    • And there you go, you are actually done, unless you want to un glue the digitizer from the screen, there's nothing else to take out. Congratulations if you made it this far. Here is a little video of all the pieces I have taken out of the laptop. (and you should have too)
