Galago Pro (Parts & Repairs)

Many components in your Galago Pro can be upgraded or replaced as necessary. Follow these step-by-step guides for instructions:

Removing the bottom cover:

Removing the cover is required to access the internal components. Prior to removing the cover, ensure the AC power is unplugged and all peripherals (including SD cards and USB drives) are unplugged or removed from the system.

Tools required: Cross-head (Phillips) screwdriver
Time estimate: 7 minutes
Difficulty: Easy

Steps to remove the bottom cover:

  1. Place the machine lid-side down.
    • Use a soft surface (such as a towel) to avoid scratches.
  2. Remove the 14 bottom panel screws.
    • The two hinge corner screws (highlighted yellow below) are slightly thicker than the rest.

Bottom panel screws

  1. Pull the bottom panel off, starting from the hinges and vents in the back.

Removing the battery:

The battery provides primary power whenever the system is unplugged.

The model number for the Galago Pro 5's battery is NV40BAT-4-49, and the original part number is 6-87-NV40S-41B01. Third-party battery sellers may list one or both of these numbers, and may offer other compatible part numbers with the same model number. You can also contact System76 to purchase a replacement battery.

Tools required: Cross-head (Phillips) screwdriver
Time estimate: 10 minutes
Difficulty: Easy

Steps to remove the battery:

  1. Follow the steps above to remove the bottom cover.
  2. Remove the five battery screws, highlighted red below.

Battery screws

  1. Unplug the battery connector (highlighted green above) and lift the battery out of the chassis.

Replacing the RAM:

The Galago Pro 5 supports up to 64GB (2x32GB) of DDR4 SO-DIMMs running at 3200MHz. If you've purchased new RAM, need to replace your RAM, or are reseating your RAM, follow these steps.

Tools required: Cross-head (Phillips) screwdriver
Time estimate: 10 minutes
Difficulty: Easy

Steps to replace the RAM:

  1. Follow the steps above to remove the bottom cover.
  2. Press the small tabs on both sides of the RAM simultaneously. The RAM should spring up to an angle.

RAM slots

  1. Remove the RAM from the slot.
  2. Insert the new RAM (or reseat the existing RAM) by placing it in the keyed slot and pressing down until it clicks into place.

Replacing an M.2/NVMe SSD:

This model supports one M.2 SSD of size 2280, PCIe NVMe Generation 4 (or Generation 3).

Tools required: Cross-head (Phillips) screwdriver
Time estimate: 10 minutes
Difficulty: Easy

Steps to replace the M.2 drive:

  1. Follow the steps above to remove the bottom cover.
  2. Unscrew the retainer screw opposite the M.2 slot.

M.2 slot

  1. Remove the existing M.2 drive by pulling it out of the slot.
  2. Insert the new M.2 drive into the slot and hold it in place.
  3. Replace the retainer screw.

Replacing the wireless card:

Your Galago Pro's WiFi and Bluetooth are both handled by the same module. It is a standard M.2 2230 slot with PCIe and USB interfaces (E-key).

Tools required: Cross-head (Phillips) screwdriver
Time estimate: 12 minutes
Difficulty: Medium

Steps to replace the WiFi/Bluetooth module:

  1. Follow the steps above to remove the bottom cover.
  2. Locate the wireless module. Remove any clear tape that is securing the wires.

Wireless card

  1. Gently remove the two antennas (highlighted red above) by pulling them up and away from the wireless card.
  2. Remove the retaining screw opposite the M.2 slot, highlighted yellow above.
  3. The wireless card will pop up at an angle. Remove the card from the M.2 slot.
  4. Insert the new wireless card into the M.2 slot at an angle.
  5. Replace the retaining screw.
  6. Attach the two antennas by aligning the circular fittings and pressing onto the wireless card. The connectors will snap into place. Use caution when attaching the connectors; the pins can bend, break, or snap.

Replacing the CMOS battery:

The CMOS battery supplies power to the system's CMOS chip. UEFI settings and the computer's hardware clock are stored on the CMOS. If your system doesn't boot, you can reset the CMOS to force a low-level hardware reset. If your clock is constantly resetting, it's likely your CMOS battery needs to be replaced.

Tools required: Cross-head (Phillips) screwdriver
Time estimate: 15 minutes
Difficulty: Medium

Steps to replace the CMOS battery:

  1. Follow the steps above to remove the bottom cover.
  2. Follow the steps above to remove the M.2 drive, then pull the battery away from the adhesive holding it to the case.
    • If you are not replacing the CMOS battery, this step is optional, but will make it easier to unplug the CMOS battery connector.

CMOS battery

  1. Unplug the white connector attaching the CMOS battery to the motherboard (highlighted green above.)
  2. To clear the CMOS, disconnect the main battery, open the lid of the machine, and hold down the power button for at least 15 seconds to discharge any residual energy in the system.
  3. Re-connect the CMOS battery and main battery, and replace the M.2 drive and bottom panel.
  4. Power up the machine. The system may power itself off and on after initial boot; this is normal behavior when the CMOS has been reset.

Replacing the cooling system:

The Galago Pro 5 has a single heatsink for the CPU and GPU (integrated or discrete). One fan is attached to the heatsink, while one additional fan is separate from the heatsink.

If a fan becomes noisy and cleaning it out doesn't fix the issue, you may need a new fan. Contact Support to start a warranty claim or parts purchase.

Depending on your climate and the age of the machine, it may be necessary to apply new thermal paste between the CPU/GPU and the heatsink. Thermal paste helps facilitate effective heat transfer between the CPU/GPU and the cooling equipment. These instructions can also be used in the unlikely event your heatsink needs replacing.

Tools required: Cross-head (Phillips) screwdriver, thermal paste
Time estimate: 20 minutes
Difficulty: High

Steps to replace the heatsink/thermal paste:

  1. Follow the steps above to remove the bottom cover.
  2. Remove any clear tape that is securing the fan wires.
  3. Unplug the white fan connector and remove the two fan screws, highlighted yellow below.

Thermal screws

  1. Remove the eight heatsink screws (highlighted cyan above) in order, starting with #1, then #2, and continuing until #8.
    • On the Intel-only model, only four heatsink screws are present.
  2. Remove the heatsink from the system, being careful not to bend the heatsink pipes. It may take some pressure to break the seal of the thermal paste.
  3. Using a paper towel, remove the existing thermal paste. You may also use a small amount of rubbing alcohol if the old paste is dried or difficult to remove.

Thermal paste removal

  1. After cleaning the CPU, GPU, and heatsink, apply a small line of thermal paste directly onto the CPU/GPU chips.
    • On the Intel-only model, only the CPU chip (on the left) is present.

Thermal paste application

  1. Carefully replace the heatsink.
  2. Replace the eight heatsink screws, starting with #1, then #2, and continuing until #8.
    • On the Intel-only model, only four heatsink screws are present.
  3. Replace the two fan screws and plug in the white fan connector.

Steps to replace the additional fan:

  1. Follow the steps above to remove the bottom cover.
  2. Remove any clear tape that is securing the fan wires.
  3. Remove the two fan screws, highlighted red below.

Fan screws

  1. Unplug the white fan connector, highlighted green above.
  2. Remove the fan from the system.

Replacing the keyboard:
