Dell Precision 5530 Disassembly

简介

This guide will breakdown the Dell Precision 5530 all the way to a mostly empty lower case. Does not cover details of removal of: power button and controller; keyboard controller; display; or front LED.

Note: this is simply one path to disassembly! Some of the parts can be removed in a different order, i.e. the keyboard does not need to be removed in order to remove the speakers (though the motherboard does).

Also note: It may be possible to remove the motherboard WITHOUT removing the heatsink, which avoids having to reapply thermal grease. I haven't checked this, but it seems likely.

Before starting, I recommend anti-static protection and a clean surface on which to work, as well as some way to differentiate between screws.

步骤 2 Bottom case

Turn off the machine, close the lid, and flip it over so it's laying upside down, hinge away from you.
Recommend a soft anti-static surface for this so as to not scratch the exterior.
Remove the ten (10) torx (T5) screws around the edges of the case.
Flip up the magnetic "lid" that says "Precision 5530" to expose the service tag and two Phillips (PH1) screws. Remove these.
Starting from the hinge side, slowly lift the rear case off. There are a few snaps, this is normal. There are no cables attached, so when it comes free, put it off to the side.

步骤 3 Battery

FIRST, unplug the battery from the motherboard (green square) by pulling the male plug towards the battery, NOT away from the motherboard. There should be a little resistance, but it should at least wiggle out.
Second, remove the seven Phillips screws around the edges of the battery (red circles) and carefully lift the battery out.
USE CAUTION! Lithium ion batteries can be dangerous if dropped or improperly handled.

步骤 4 Remove the RAM

The two RAM sticks are right in the center of the machine.
Locate the two metal latches (green boxes) on either side of the RAM stick, Push both of these away from the RAM, which should pop the memory stick out of the slot. Repeat for the second stick, if applicable.
Note: see previous step for RAM installed. In this image, both RAM sticks have been removed.

步骤 5 Remove the hard drive

This machine does NOT have an HDD (this would be in the pink box), only an SSD (orange box). The SSD has been removed already in this image.
To remove the SSD, unscrew the single Phillips screw to the left of the drive (red circle). The drive should pop out smoothly.

步骤 6 Remove the heatsink

Dell Precision 5530 Disassembly, Remove the heatsink: 步骤 6 中的图像 3，3

It may be possible to skip this step entirely and remove the motherboard and the heatsink as one unit! If you go this route, be warned that this guide does not cover this procedure and you risk damaging your machine (but avoid having to deal with thermal paste). However, you must still remove the right fan brace (see below).
First, remove the fan brace (orange box, image 1) by removing the two Phillips screws (red circles, image one).
Second, remove the five screws (red circles, image two) that hold the heatsink in place. Note that one of the screws is under a piece of tape.
Use caution when removing the heatsink! It's thermally stuck (just grease, not adhesive) to the CPU and GPU, but it should just peel off, no problem.
IMPORTANT! If you remove the heatsink, you will need to remove and reapply thermal grease onto the CPU and GPU, as well as making sure that you do not lose any of the thermal tape that is on the other chips on the motherboard (the tape is grey and a bit sticky).

步骤 7 Remove the fans

Dell Precision 5530 Disassembly, Remove the fans: 步骤 7 中的图像 2，2

There are two fans (orange boxes). Three Phillips screws (red circles) will remove them, one for the right fan and two for the left. (The second screw for the right fan was removed when the metal brace was removed.)
The display cable must be disconnected. To do so pull UP (meaning away from the motherboard) on the connector (highlighted in green). The connector has a pull tab that helps in this. Once the plug has been disconnected, the cable can be threaded out around the right fan socket.

步骤 8 Remove the WiFi card

The WiFi card is on the top left of the machine (highlighted in orange) Remove the single Phillips screw (red circle) to remove the WiFi card and the small metal bracket.

步骤 9 Remove the motherboard

Dell Precision 5530 Disassembly, Remove the motherboard: 步骤 9 中的图像 2，2

Note: in the first image, the WiFi card is still in place, but it needs to be removed before the motherboard can be removed. See step 8 for that process.
There are five cables that must be removed. Two are standard plugs (highlighted in orange: the charging cable (top), and the speakers (bottom)) and three are locking ribbon cables (highlighted in pink (from left: power button, trackpad, keyboard)).
Be very careful with the locking ribbon cables! It's easy to pull them off the motherboard entirely! If you're not comfortable removing these, look up a video or other instruction set for how to handle these.
There are then four Phillips screws (red circles) that need to be removed.
Finally, the motherboard can be removed. USE CAUTION! Pull it up away from the machine slightly, and then slide it away from the hinge. It should come out easily.

步骤 10 Pause to appreciate

Just a brief pause to appreciate the hardware inside this machine.
To remove the thermal paste, isopropyl alcohol is a standard way to do this in conjuction with a tissue or Qtip.
Image one is the left side of the motherboard. The big chip is the GPU, the nVidia Quadro ~~P4000~~ P2000 (EDIT: thanks @Julianmustofa!). As noted by @Kisai, the taped over chips (image two) are likely GDDR memory chips for the GPU, 1GB each for a total of 4GB of GDDR memory (part number 8HA47 D9SXD with a stylized "M" printed on them).
Image three is the CPU, in this case a Intel Core i7-8850H CPU at 2.60GHz. The large chip on the lower edge is possibly a memory controller or a north bridge like chip - there was no easily found part number.
There are obviously numerous other chips on the front and underside of the board, and perhaps in a future teardown, I'll break them all down.

步骤 11 Remove the keyboard

Take a deep breath - this is the most obnoxious portion of the disassembly.
First, the two black tape covers must be removed (highlighted in orange).
Neither is on super tight, and both can be done with only your hands.
For the larger one, it helps to start near the hinge, move down, and then move across. Be careful along the hinge edge! There are some cutouts that can easily tear.
Next, looking at image two, there are two locked ribbon cables (orange boxes) and 32 (thirty-two!!) tiny Phillips screws (red circles) to remove. Have fun!
The keyboard can then be simply lifted out of the case.

步骤 12 Remove the trackpad controller

Dell Precision 5530 Disassembly, Remove the trackpad controller: 步骤 12 中的图像 2，2

The trackpad controller (orange box) can be removed with two Phillips screws (red circles) and the removal of some grounding tape (silver, in pink box).
The grounding tape is kinda sticky, but is very important! The trackpad won't work if it's not connected properly, so when re-assembling, be careful to correctly replace this.
The trackpad (image 2, in orange) can be removed by pressing it out through the topside of the case (i.e. when the computer is opened).

步骤 13 Remove the speakers

Dell Precision 5530 Disassembly, Remove the speakers: 步骤 13 中的图像 1，1

The speakers (highlighted in orange) can be removed with four Phillips screws (red circles).
The four screws have pink gaskets around them, and only three are visible in the image due to the aspect ratio requirements. (The fourth is indicated in the image by a red arrow.)

步骤 14 Last bits

Dell Precision 5530 Disassembly, Last bits: 步骤 14 中的图像 1，1

I did not do any further removal. The following steps are identification of the last bits that can be removed. Proceed with caution!
Highly likely that these bits are easy to remove.
Orange box: front LEDs. Remove the locking ribbon cable first.
Pink box: keyboard controller. There's likely a screw under the grounding tape on the right.
Green box: power button and controller.
Yellow boxes (left and right): hinge and display attachment points.
Removal of the display and replacement of display components is not covered here.

结论

To reassemble your device, follow these instructions in reverse order.

Be aware that if you removed the heatsink, you MUST MUST MUST (MUST) reapply thermal paste! If you do not, your machine may be irreparably damaged when you first use it! If you're lucky, the CPU will go into over-temperature protection mode before this happens, but no guarantees!

Second thing to remember is to re-attach all grounding tape as it was originally attached! Don't forget this! If you're lucky, it'll just mean that the trackpad doesn't work properly. If not, you could damage or destroy the machine via static shock.
