In order to use the extracted tables we have to override it.Ĭreate the necessary directory if it does not exist already: ![]() The thermald service file shipped with Arch Linux enables adaptive mode by default. The tool also creates a copy of each of these files in the current working directory, so you may want to remove those: This will populate /etc/thermald/ with multiple configuration files of the form thermal-conf.xml.*, each of which represents a converted DPTF table. Next, use Intel's proprietary dptfxtract-bin AUR tool to extract the DPTF tables: While the CPU's limit is raised to 45W/83C, the all-core frequency is erratic, resulting in only a marginal performance improvement.įix using dptfxtract and manual DPTF profile settingĪnother option, which does result in full performance, is to extract the DPTF tables and use them in combination with a manual change of the DPTF profile.Ĭonfiguring thermald to use extracted dptf tablesįirst, make sure thermald is installed. Unfortunately, the current implementation does not appear to help much on this laptop. Starting with kernel 5.12, the work-in-progress can be utilized by installing and enabling thermald, which will attempt to make use of the firmware's adaptive performance policy. Most of the work has been upstreamed already, though the implementation is still far from complete. There is an ongoing effort to reverse-engineer DPTF on Linux. While newer generations of ThinkPads have gotten a BIOS update to fix this, a Lenovo employee confirmed that older affected Thinkpads (including T580, T480, T480s, X1C6, P1G1 and X1E1) will not get the fix.Ī stress test using s-tui indicates that the CPU is limited to 38W/80C at boot, resulting in a sustained all-core frequency of around 2850 MHz on the i7-8750H.įix using reverse-engineered DPTF implementation This laptop is affected by a CPU throttling bug when using Linux.īasically, the laptop's firmware uses an implementation of Intel's Dynamic Platform and Thermal Framework (DPTF) that does not work with Linux. The dedicated GPU cannot be disabled through firmware, so enabling runtime power management in some form is highly recommended when using the iGPU. All information on this page assumes the latest firmware.īoth the HDMI port and DisplayPort outputs created when using either a USB-C adapter or Thunderbolt dock are wired to the Nvidia dGPU.Ī BIOS setting can be used to disable the integrated GPU, and run everything on the dedicated Nvidia card. The latest version, v1.35, is highly recommended. Firmware updateĪ UEFI firmware update is strongly recommended for general use of the laptop - the initial 1.13 version devices seem to ship with contains multiple bugs that can result in bricking the laptop: Reddit thread discussing the issue another Reddit thread discussing a different bricking issue.įirmware updates are available via fwupd, the Lenovo Vantage application on Windows, or from Lenovo's website. Most of the information on this page should be applicable to P1 models as well. When reinstalling Windows, try the Lenovo disc images, as longer battery times have been reported, probably due to custom drivers.Note: The Lenovo ThinkPad P1 is a workstation version of the same laptop which uses extremely similar hardware. ![]() A can of compressed air may be useful too, and a bottle of isopropyl alcohol and cotton buds are good for cleaning, but not on the screen. The only tools you need for servicing a ThinkPad are a set of small screwdrivers and a nylon spudger (for taking the screen and keyboard bezels off), and possibly a pair of tweezers. Corporate bulk purchasers don't usually go for it. Not only will it have better brightness, colour, contrast and viewing angles - you will most probably more than make up the investment when selling it. ![]() When buying a new ThinkPad, consider taking the IPS screen option if possible, as it doesn't cost much. When buying a used ThinkPad, remember to check that the BIOS is not locked with a supervisor's password and that Computrace is not enabled and activated.
