The temperature they reach depends on the amount of system activity and the level of charge in the battery.
Handle your computer gently. Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy objects on your computer, display, or external devices. Carry your computer carefully. • Use a quality carrying case that provides adequate cushioning and protection. • Do not pack your computer in a tightly packed suitcase or bag. • Before putting your computer in a carrying case, make sure that it is off, in sleep mode, or in hibernation mode.
