Care and cleaning
Protect your Surface from viruses
Windows Defender and Windows SmartScreen are built into Windows 8.1 to help guard against
viruses, spyware, and other malicious software in real time. For more info, see Security checklist for
Windows and How can I help protect my PC from viruses? on Windows.com.
To scan Surface manually, use Windows Defender. See How do I find and remove a virus? on
Windows.com for how-to info.
Touchscreen care
Scratches, finger grease, dust, chemicals, and ultraviolet light can affect the performance of the
touchscreen. Here are a few things you can do to help protect the screen:
Clean it frequently. Wipe the touchscreen with a soft, lint-free cloth to clean it. You can
dampen the cloth with water or an eyeglass cleaner, but don’t apply liquids directly to the
touchscreen. Don’t use window cleaner or other chemical cleaners on the touchscreen.
Keep it covered. Close the Cover or use a sleeve when you’re in transit or not using your
Surface.
Keep it out of the sun. Don’t leave your Surface in direct sunlight for a long time. Ultraviolet
light and excessive heat can damage the touchscreen.
Cover care
The Type Cover requires minimal care to function well. Clean the keyboard frequently by wiping it
with a lint-free cloth dampened in mild soap and water, but don’t apply liquids directly to the
Cover.
If the spine or magnetic connections of your Cover get dirty or stained, apply a small amount of
isopropyl alcohol (rubbing alcohol) to a soft, lint-free cloth to clean.
Battery care
Operating temperature. Surface is designed to work between 32°F and 95°F (or 0°C to 35°C).
Lithium-ion batteries are sensitive to high temperatures, so keep your Surface out of the sun
and don’t leave it in a hot car.
Recharge any time. The battery doesn’t need to be empty or low before you recharge it. You
can recharge the battery whenever you like. However, it’s best to let the battery run to below
10 percent at least once per month before you recharge it.
