SVALT Cooling Dock Operation

The following explains how to operate a SVALT Cooling Dock based on model and firmware version:
  • SVALT D2 Operation with Cooling System Firmware Version 2.0
    (v2.0 included with D2’s shipped after August 7, 2017)

    Quick Operation
    To turn on the D2, press the push-button switch once (1x) and the cooling system will start in Auto cooling mode by default (see Advanced Custom Operation below to change cooling modes). Once you’ve pressed the switch and enabled Auto cooling mode, then an LED inside the bottom of the rear screen will light up and then pulse for 24-seconds, while the fan instantly spins to maximum speed and then drops down to a lower speed or turns off based on measured temperature.

    To turn off the D2, wait a few seconds if you just powered on the D2, and then press the switch once (1x) to power down the cooling system. Once you’ve pressed the switch, then the LED will momentarily light up and fade to off in 1-second, while the fan spins to a stop.

    Standard Auto Operation
    In any of the three Auto cooling modes the cooling system responds intelligently to laptop temperatures for simple set-it-and-forget-it operation. An external sensor measures laptop temperatures and automatically adjusts fan speeds from 900 to 3600 RPM to meet audio and cooling performance requirements over the course of a workday. When temperatures are low enough the fan will temporarily stop until higher temperatures are detected, at which point it will automatically restart.

    A LED is located inside the rear screen, along the bottom of the fan. The LED is positioned to be visible when leaning over the laptop and looking down the back side of the dock. The LED illuminates in response to user switch inputs and visually signals the current cooling mode state. After changing cooling modes, the fan momentarily speeds up to provide an audio signal of the mode change. The LED stays on for 24-seconds after powering on the cooling system or making a cooling mode change. If the fan stops after enabling one of the Auto cooling modes, then the LED will continue to signal the cooling mode for 24-seconds and the fan will automatically restart once higher temperatures are detected. The LED turns off 1-second after powering down the cooling system.

    Advanced Turbo Operation
    After turning on the D2 by pressing the switch 1x, you can then use the following switch activations to immediately increase fan speed to 3200 RPM for an extra blast of cooling power. These Turbo cooling modes are temporary and do not change the saved cooling mode.
    • 2x Turbo (rapid flashing LED) When you press switch 2x the cooling system will enable Turbo and then automatically return to the default Auto cooling mode, or the last user saved cooling mode after 5-min.
    • 3x Turbo + (medium flashing LED) When you press switch 3x the cooling system will enable Turbo until you press the switch 1x to return to the default Auto cooling mode, or the last user saved cooling mode.

    Advanced Custom Operation
    After turning on the D2 by pressing the switch 1x, you can then use the following switch activations to change the saved cooling mode. Once one of these modes has been enabled, then the D2 will return to that cooling mode upon subsequent power restarts.
    • 4x Fixed (slow flashing LED) When you press the switch 4x the cooling system will run at a constant 1600 RPM fixed speed by default to provide a balance of audio and cooling performance, or you can save a custom fixed speed to precisely meet your audio and cooling performance requirements as described below in 5x Fixed Customization.
    • 5x Fixed Customization (LED pulses up and down to indicate rising or falling fan programming speeds) When you press the switch 5x the fan will begin to continually cycle from 900 to 3600 to 900 RPM. Press the switch 1x when the fan reaches your desired fixed speed. At this point you have saved a custom fixed speed and entered into 4x Fixed cooling mode. If you change cooling modes and then return to 4x Fixed cooling mode, it will return to your custom fixed speed. If you would like to select a different fixed speed, then press the switch 5x to restart the process, or you can reset to the default 1600 RPM as described below.
    • 6x Auto + (rapid pulsing LED) When you press the switch 6x the cooling system will run at higher speeds for cooling priority. In this cooling mode the fan is more likely to stay on at low to moderate speeds, and will increase speeds sooner to help stay ahead of heat buildup. This cooling mode is suggested for cooler offices.
    • 7x Auto (medium pulsing LED) When you press the switch 7x the cooling system will run at default speeds for a balance of audio and cooling performance. In this cooling mode the fan will stay off or at lower speeds until temperatures rise, as which point fan speeds will progressively increase to help neutralize heat buildup. This cooling mode is suggested for offices with normal temperatures.
    • 8x Auto - (slow pulsing LED) When you press the switch 8x the cooling system will run at lower speeds for audio priority. In this cooling mode the fan will stay off or at lower speeds until temperatures rise significantly, at which point fan speeds will rapidly increase to help recovery from heat buildup. This cooling mode is suggested for hotter offices.

    Factory Default Reset Operation
    To reset the cooling system to factory defaults press and hold the switch for 5-seconds. Once the switch has been held down for 5-seconds and a system reset has been triggered, the fan will speed up and the system will enter into Auto default cooling mode and the LED will medium pulse. The Fixed cooling mode will also have been reset to 1600 RPM.

    • 4x Fixed (medium flashing LED) Press switch 4x to set the cooling system to a fixed speed of your choosing. The fan continually cycles from 900 to 3600 to 900 RPM, while the LED indicates increasing or decreasing speeds. When the fan reaches your desired speed, press the switch 1x to select a fixed speed, at which point the LED will medium flash. Press switch 4x to restart the selection process. In this Fixed cooling mode you can lock-in the precise fan speed that provides the right balance of audio and cooling performance for your requirements.
    • 5x Auto - (slow fading LED) Press switch 5x to set the cooling system to a lower speeds for audio priority, or for a hot office as compared to normal 70 F office temperatures. In this Auto cooling mode the fan will stay off or at lower speeds until temperatures rise significantly, at which point fan speeds will rapidly increase to help recovery from heat buildup.
    • 6x Auto + (fast fading LED) Press switch 6x to set the cooling system to a higher speeds for cooling priority, or for a cold office as compared to normal 70 F office temperatures. In this Auto cooling mode the fan is more likely to stay on at low to moderate speed, and will increase speeds sooner to help stay ahead of heat buildup.
    • 7x Auto (medium fading LED) Press switch 7x to reset the cooling system to factory default for a balance of audio and cooling performance in normal 70 F office temperatures. In this Auto cooling mode the fan will stay off or at lower speeds until temperatures rise, as which point fan speeds will progressively increase to help neutralize heat buildup.

  • SVALT D2 Firmware Upgrade
    Please contact us to upgrade your D2’s cooling system firmware to Version 2.0. If you cover shipping costs, then we will upgrade the firmware and clean your Cooling Dock at no charge. And we are offering a special promotion that can be used to help covered shipping costs.

    The following outlines Version 2.0's main revisions from Version 1.0:
    • 4x Fixed cooling mode has been revised to start with a default 1600 RPM fixed speed or a user’s saved custom fixed speed.
    • 5x Fixed Customize cooling mode has been added as a separate mode for the user to select a custom speed for 4x Fixed cooling mode. This allows the cooling system to save the user’s custom fixed speed so that it can be reactivated without having to reselect a fixed speed, which can be helpful when a user wants to change between modes to meet various audio or cooling performance scenarios.
    • 6x Auto + cooling mode has been revised with significantly more aggressive mapping.
    • 7x Auto default cooling mode has been revised with slightly more aggressive mapping.
    • 8x Auto - cooling mode has been revised with slightly less aggressive mapping.
    • The reset to factory default has been revised to reset Fixed cooling mode to the default 1600 RPM.
    • The order of cooling modes has been revised along with associated switch activations required to enable the cooling modes.

  • SVALT D2 Firmware Customization
    We have done a lot of research and testing to dial in the firmware settings to work for as many users as possible, so we recommend sticking with the standard firmware. However, if you work in unusual conditions or just want to dial in settings for your particular needs, then we can create a custom tailored D2 firmware for $20. If you are interested in this service, then you can add a note when you place an order, contact us before your order has shipped, or let us know when you send in your D2 for a firmware upgrade.

    The following firmware parameters can be changed per your preference:
    • 2x Turbo cooling mode's 3200 RPM can be changed to any speed between 900-3600 RPM.
    • 2x Turbo cooling mode’s 5-minute run time can be changed to any length of time between 30-seconds and 8 hours.
    • 3x Turbo + cooling mode’s 3200 RPM can be changed to any speed between 900-3600 RPM.
    • 4x Fixed cooling mode’s 1600 RPM default can be changed to any speed between 900-3600 RPM.
    • 6x Auto + / 7x Auto / 8x Auto - cooling mode’s temperate and speed response curves can be changed to your preference with temperature settings between 0-45 degrees Celsius and fan speed settings between off and 900-3600 RPM. For instance, you can set the fan to stay off until a certain temperature is reached, then gradually or steeply increases, or alternatively, the fan can always stays on, etc. You can provide a narrative description of what you are looking for, or provide more details with desired temperature and speed responses. You can also download the diagrams from v2.0 or v1.0, and then sketch over the existing curves with what you prefer.
    • The order of cooling modes can be rearranged, along with the cooling mode’s associated switch activations and LED signals.
