Apple Macintosh PowerBook 150 - Manual (Page 60)

Important
m If the computer has been in a cold place for several hours, let it warm up to
room temperature before you use it.
m Use the computer only in environments where the temperature range is
between 50°F/10°C and 104°F/40°C.
m Do not expose the computer to very low (less than –13°F/–25°C) or very
high (more than 140°F/60°C) temperatures.
m Clean the computer’s outside surfaces with a damp (not wet) cloth. Clean
the screen with soft, lint-free paper or cloth and a mild glass cleaner. Do
not spray the glass cleaner directly onto the screen.
Caring for batteries
m Always handle batteries carefully.
m Do not short-circuit the battery terminals (that is, do not touch both
terminals with a metal object). Doing so may cause an explosion or a fire.
m Do not drop, puncture, disassemble, mutilate, or incinerate the battery.
m Recharge batteries only as described in this manual and only in ventilated
areas.
m Do not leave batteries in hot locations (such as the trunk of a car) for more
than a day or two.
m Do not leave a battery in your computer for longer than a week without
plugging in the power adapter.
m Do not leave a battery in storage for longer than 6 months without
recharging it.
m Take dead batteries to an Apple-authorized service provider for recycling or
proper disposal. The batteries contain hazardous chemicals and should not
be thrown out with household or office trash.
