Be careful about where and how you work • Store packing materials safely out of the reach of children to prevent the risk of suffocation from plastic bags. • Keep your computer away from magnets, activated cellular phones, electrical appliances, or speakers (within 13 cm or 5 inches). • Avoid subjecting your computer to extreme temperatures (below 5°C/41°F or above 35°C/95°F). • Some appliances, such as certain portable desktop fans or air purifiers, can produce negative ions. If a computer is close to such an appliance, and is exposed for an extended time to air containing negative ions, it might become electrostatically charged. Such a charge might be discharged through your hands when you touch the keyboard or other parts of the computer, or through connectors on I/O devices connected to it. Even though this kind of electrostatic discharge (ESD) is the opposite of a discharge from your body or clothing to the computer, it poses the same risk of a computer malfunction. Your computer is designed and manufactured to minimize any effects of electrostatic charge. An electrostatic charge above a certain limit, however, can increase the risk of ESD. Therefore, when using the computer close to an appliance that can produce negative ions, give special attention to the following: • Avoid directly exposing your computer to the air from an appliance that can produce negative ions. • Keep your computer and peripherals as far as possible from such an appliance. • Wherever possible, ground your computer to facilitate safe electrostatic discharge. Note: Not all such appliances cause a significant electrostatic charge. Be gentle with your computer • Avoid placing any objects (including paper) between the display and the keyboard or the palm rest. • Your computer display is designed to be opened and used at an angle slightly greater than 90 degrees. Do not open the display beyond 180 degrees, as this might damage the computer hinge. • Do not turn your computer over while the ac power adapter is plugged in. This could break the adapter plug. Carry your computer properly • Before moving your computer, be sure to remove any media, turn off attached devices, and disconnect cords and cables. • When picking up your open computer, hold it by the bottom. Do not pick up or hold your computer by the display. Handle storage media and drives properly • Store your external hard disk drive in the appropriate containers or packaging when they are not being used. • Before you install a memory card such as an SD card, SDHC card, SDXC card, and a MultiMediaCard, touch a metal table or a grounded metal object. This action reduces any static electricity from your body. The static electricity could damage the device. • When transferring data to or from a flash media card, such as an SD card, do not put your computer in sleep or hibernation mode before the data transfer is complete; otherwise, your data could become damaged. Take care in setting passwords • Remember your passwords. If you forget a supervisor or hard disk password, Lenovo will not reset it, and you might have to replace your system board or solid state drive. Chapter 7. Preventing problems 83

Be careful about where and how you work
•
Store packing materials safely out of the reach of children to prevent the risk of suffocation from plastic
bags.
•
Keep your computer away from magnets, activated cellular phones, electrical appliances, or speakers
(within 13 cm or 5 inches).
•
Avoid subjecting your computer to extreme temperatures (below 5°C/41°F or above 35°C/95°F).

Some appliances, such as certain portable desktop fans or air purifiers, can produce negative ions. If a

when you touch the keyboard or other parts of the computer, or through connectors on I/O devices
