 WARNING! Keep out of reach of small children

Your device and its accessories are not toys. Keep your device and all its parts and accessories out of the reach of small children. Children could hurt themselves or others or damage your device. In addition, the device may contain or break into small parts that may be a choking hazard to children under 3 years.

 WARNING! Prolonged contact with warm devices

Your device and its power supply unit (PSU) may become warm during normal use. It complies with the surface temperature limits defined by international safety standards; nonetheless, sustained contact with warm surfaces may cause injury. For example, if you rest the warm device on your lap for a long time, you might sustain an injury even though it may not feel hot to the touch. If you have a condition that affects your ability to detect heat or your sensitivity to heat, then you may be particularly susceptible to such injuries.

To reduce this risk:

  • Avoid sustained skin contact with your device or its PSU when it’s operating or connected to a power source. For example, don’t sleep with your device or its PSU.

  • If your device is on your lap and gets uncomfortably warm, move it to a stable work surface.

  • Keep your device and its PSU in a well-ventilated area when in use or charging. Allow for air circulation around the device and its PSU. Don’t place your device or its PSU under a blanket or pillow or use it on soft surfaces.

Note: Potential damage to surfaces. Never place your device or its PSU on furniture or any other surface that might be marred by exposure to heat.​​​​​​​

 WARNING! AC power supply safety

Always select and use an appropriate AC power supply for your device. Failure to take the following precautions can result in serious personal injury or death from electric shock or fire or in damage to your device.

To select an appropriate power source for your device:

  • We recommend you use genuine Microsoft power supply units (PSUs) and AC power cords. A genuine Microsoft PSU was provided with your device., or can be purchased from a Microsoft-authorized retailer and at store.microsoft.com/devices.

  • Use only AC power provided by a standard (mains) wall outlet. Do not use non-standard power sources, such as generators or inverters, even if the voltage and frequency appear acceptable.

  • Confirm that your electrical outlet provides the type of power indicated on the PSU (in terms of voltage [V] and frequency [Hz]). If you are unsure of the type of power supplied to your home, consult a qualified electrician.

  • Do not overload your wall outlet, extension cord, power strip, or other electrical receptacle. Confirm that they are rated to handle the total current (in amps [A]) drawn by your device (as indicated on the PSU) and any other devices using the same circuit.

  • For devices where the AC prongs may be folded for storage, make sure its prongs are fully extended before plugging the AC power supply for your device into the power (mains) outlet.

  • For devices equipped with power cords with removable prongs and a universal power supply, make sure the prong assembly is properly configured for the power outlet and fully seated into the power supply before plugging the AC power supply into a power (mains) outlet.

 WARNING! Power cord and cable safety

Damaged power cords and cables can pose an electric shock or fire hazard, and exposed device cables and cords pose a potential tripping hazard. Arrange all cables and cords so that people and pets are not likely to trip over or accidentally pull on them as they move around or walk through the area. Do not allow children to play with cables and cords. To avoid damaging the cords and cables:

  • Protect cords from being walked on or crushed.

  • Protect cords from being pinched or sharply bent, particularly where they connect to a wall power (mains) outlet, the power supply unit, and your device.

  • Do not jerk, knot, sharply bend, stretch, or otherwise abuse the power cords. Do not wrap your power cord too tightly, especially around the power brick. Instead, wrap it using loose coils rather than tight angles.

  • When positioning your device or PSU make sure that the cords are not bent sharply and that the connectors are not pushed against a wall or hard surface.

  • Do not expose power cords to heat sources.

  • Do not allow pets or children to bite or chew on power cords.

  • When disconnecting the power cord, pull on the plug—do not pull on the cord.

Inspect your power cords and cables regularly. If a power cord or cable becomes warm, frayed, cracked or damaged in any way, stop using it immediately. We recommend that you replace your damaged power cord or cable with a genuine Microsoft replacement power cord or cable.

Unplug your power cord during lightning storms or when unused for long periods.

 WARNING! Keep power supply unit (PSU) DC connector clean

Note: Does not apply to Surface USB-C Wall Charger

Avoid prolonged skin contact with the DC connector when your power supply unit (PSU) is plugged into a power source because it may cause discomfort or injury. Sleeping or sitting on the DC connector should be avoided.

Keep the DC connector clean, free of contaminants such as liquids, sweat, or dirt. To clean, wipe it with a clean cloth. Using a contaminated DC connector can result in heating, which can cause discomfort or injury. If this occurs, immediately unplug the DC connector from the device.  ​​​​​​​
