General Safety Precautions
• Opening and/or repairing any electronic device can present a risk of electric shock, fire,
serious personal injury, death, damage to the device or other property, and/or other
hazards. Exercise caution when undertaking the repair activities described in this Guide. The
repair activities identified in this Guide should only be undertaken by technically inclined
individuals with the knowledge, experience, and specialized tools required to repair
Microsoft devices.
• Improper use or handling of devices or their batteries may result in fire or explosion. Only
open the enclosure on a device as outlined in this Guide.
• Do not heat, puncture, mutilate, or dispose of devices or their batteries in fire. Do not leave
or charge devices in direct sunlight or expose devices or their batteries to temperatures
outside the recommended operating range of 0°C to 60°C/32°F to 140°F for an extended
period. Doing so can result in battery failure, electric shock, fire, serious personal injury,
death, and/or damage to the device or other property.
• We recommend wearing protective eyewear and gloves when disassembling/re-assembling
a device.
• Clean your work surface regularly to remove debris and abrasive particles.
• While working on devices, avoid the use of clothing accessories such as bracelets or
watches that can cause electrical shorts and/or damage the battery. If battery damage (e.g.,
leaking, expansion, folds or other) is discovered during device repair or if the battery is
impacted or damaged during replacement, DO NOT proceed. Refer to Actions to Take
under Handling Used, Damaged or Defective Lithium-Ion Batteries in this Guidebook or
contact Microsoft directly for proper device disposition.
