Battery Safety
This device contains either a built-in or removable (cartridge) lithium-ion rechargeable
•
battery. Battery safety is a significant concern when repairing a device.
For optimum compatibility, performance, and product safety, we recommend using
•
genuine Microsoft replacement parts. Use of non-Microsoft (non-genuine), incompatible,
reused, or modified batteries; improper battery installation; improper handling or storage
of batteries; and/or failure to follow the instructions in this Guide could cause battery
overheating, expansion, venting, leaking, or a thermal event which could result in fire,
serious personal injury, death, data loss, or damage to the device or other property
damage.
Before beginning device repair, ensure your workspace is free of flammable debris or
•
materials, has adequate ventilation, and that you have a fire suppressant device (example:
fire blanket, container of sand, Class B fire extinguisher) within easy reach or you are within
20 feet of a fireproof enclosure. Fireproof enclosures should be kept free of combustible or
flammable materials.
: Only handle battery by plastic enclosure. Bending, twisting, or impacting
battery may damage the battery, damage the device, and/or result in severe personal
injury or property damage. Always use two hands when handling the battery.
IMPORTANT: Place the battery in a location where it cannot be accidentally contacted or
damaged. When replacing the battery dispose of the old battery according to local laws
and regulations.
Use personal protective equipment (PPE) when handling damaged, venting, or hot battery
•
packs.
Use the following best practices when handling batteries:
•
Always fully discharge batteries by running an application such as video
▪
playback with the device unplugged. If the device does not function while
