Handling Precautions
Warning:
1.Staticelectricitymaycausedamage tothe integrated circuitson
the motherboard.Beforehandling anymotherboardoutside ofits
protectivepackaging,ensurethatthereisno staticelectric
charge inyourbody.
2.Thereisadangerofexplosion ifthe batteryisincorrectly
replaced.Replaceonlywiththe sameoran equivalenttype
recommended bythe manufacturer.
3.Discardused batteriesaccording tothe manufacturer’s
instructions.
4.Neverrun the processorwithoutthe heatsinkproperlyand firmly
