  2. Once the Heat Sink and CPU core are free of old Thermal Paste, apply new paste in a line down the middle of the CPU core (fig. 37).
  3. Once the paste is applied, replace the Heat Sink over top of it. The Heat Sink will spread the thermal paste across the CPU core, there is no need to spread it yourself.
  4. Re-fasten the four (4) screws on the Heat Sink. In fastening the screws, partially tighten them one at a time, and move diagonally to the opposite corner. For example, tighten the top-left screw halfway, then move to the bottom right, and tighten that halfway. Repeat until all screws are tight. This ensures even pressure between the brackets and the motherboard.
  5. Once the Heat Sink is fastened down, clip the CPU Cooling Fans back onto the Heat Sink.
  6. Reconnect the power cables to the CPU Cooling Fans.
  7. Follow the steps in Replacing the GPU (if applicable).
  8. Next, follow the steps in Replacing the CPU Cooler Shroud.
  9. Follow the steps in Replacing the Top Case.
  10. Reconnect all external cables and peripherals, and turn the Power Supply switch to the “on” position.
  11. Power on the Thelio to ensure successful boot.

NOTE: The pictures shown here are the Thelio R1 (AMD) model with a Threadripper processor. However, the process and cautions when removing and replacing thermal paste are the same for both Intel and AMD Thelio Majors.

Components

System76 uses a wide variety of component vendors, including:

Intel

Intel produces CPUs, PCHs, and other components for System76.

Intel CPUs

Intel Comet Lake-U (CML-U) CPU

The Intel Comet Lake-U CPU is designed for mobile devices and includes an integrated PCH, the Intel 400 series chipset. The available SKUs may be seen at the Intel ARK.

Documentation

Documentation for the CML-U CPU may be found at the Intel Resource and Design Center. Some documentation may require signing an NDA. After logging in with a privileged account, the Comet Lake U Technical Library will be available with all relevant documentation.

Firmware Support

Support for the CML-U CPU is provided by the following:

  • coreboot soc/cannonlake
    • Configured by mainboard source code and build configuration
    • Correct mainboard source code and build configuration is provided with System76 firmware
  • Intel Firmware Support Package (FSP) CometLakeFspBinPkg/CometLake1
    • Configured using Updateable Product Data (UPD)
    • UPDs are set by coreboot based on mainboard source code and build configuration
    • Correct mainboard source code and build configuration is provided with System76 firmware
  • Intel Graphics Output Protocol (GOP) 9.0 - Optional
    • Configured using the Video BIOS Table (VBT)
    • VBT is edited using Intel Binary Modification Program (BMP)
    • Sample VBT is available from Intel FSP repository
    • Correct VBT is provided with System76 firmware
  • Intel Management Engine (ME) 14.0
    • Configured using the Intel Firmware Descriptor (FD) as well as ME filesystem
    • Intel FD and ME filesystem is edited by Intel Flash Image Tool (FIT)
    • Correct Intel FD and ME is provided with System76 firmware
  • Intel Microcode
    • Comet Lake U42 - 806EC
    • Comet Lake U64 - A0660
    • Correct microcode is provided with System76 firmware
  • Model-specific configuration can be found in model documentation

Intel Management Engine (ME)

The Intel Management Engine is integrated into the Intel Platform Controller Hub (PCH). It participates in the CPU and PCH boot process, and has runtime components to implement functionality that is not implemented in CPU firmware, such as firmware TPM (fTPM).

Documentation

Documentation is difficult to find. Incomplete information about the Intel ME can be found on Wikipedia. Sometimes confidential information is found on the Intel Resource and Design Center, especially where the firmware has to communicate with the Intel ME in order to boot the system.

Releases

Intel ME versions follow a format of GENERATION.SKU.HOTFIX.BUILD. Releases are done at the Intel Validation Internet Portal. It is up to the motherboard manufacturer to configure the Intel ME using the Intel Flash Image Tool (FIT), which produces a distributable firmware image. It is not permitted to distribute the Intel FIT to the end user. System76 closely monitors for Intel ME releases and updates our firmware images as necessary.

Neutralization

The Intel ME poses potential security security risks due to its access to the system and an inability for users, even including motherboard and firmware vendors, to audit the source code of the Intel ME firmware. Disabling all functionality of the Intel ME is not possible. Methods for disabling runtime components vary between versions. System76 Open Firmware disables runtime components of the Intel ME using the most capable method possible.

Intel Platform Controller Hub (PCH)

The Intel Platform Controller Hub provides I/O to Intel CPUs, typically over the Direct Media Interface.

Intel 400 Series Low-Power PCH (400 PCH-LP)

The Intel 400 Series Low-Power PCH is integrated into the Intel Comet Lake-U (CML-U) CPU, so information can be found there instead.

Texas Instruments (TI)

Texas Instruments produces a number of components for System76.
