Apple Duo 270C Recharging the battery, Recharging in the computer, There are two ways to recharge

The second message is followed by a third and final message indicating that the computer is about to put itself to sleep. When time is up, the computer goes to sleep automatically to protect the contents of RAM. Some functions (such as modem connections) are interrupted when the computer goes to sleep. It’s a good idea to save your work when you see the first two low- power messages to make sure you don’t lose data.

If you continue working until the computer goes to sleep automatically, you can wake it again as soon as you plug in the power adapter or replace the battery with a fully-charged battery.

If you can’t plug in the power adapter, the contents of RAM are retained in sleep for about a day. If you leave the battery in the computer and recharge it within a day, you should be able to wake the computer and resume work where you left off.

SImportant: A depleted battery can be left uncharged in the computer for a month or two if the computer is stored at room temperature or below. Don’t store the computer or its battery in a hot location (such as the trunk of a car). Heat may damage the battery so that it can’t be recharged. If this happens, you need to replace the battery. S

nPlug in the power adapter to recharge the battery without removing it from the computer, or
