to an optimal operating temperature before use could result in irreparable damage
to your computer.
If possible, place your computer in a well-ventilated and dry area without direct
exposure to sunshine.
Keepelectricalappliancessuchasanelectricfan,radio,high-poweredspeakers,

devices. If liquid is spilled on or in the computer or an attached device, a short
circuit or other damage might occur.
Do not eat or smoke over your keyboard. Particles that fall into your keyboard can
