Acer Backup Manager

Note: This feature is only available on certain models.

Acer Backup Manager is a utility that enables you to do a variety of

backup functions each accomplished in only three simple steps. You can

even set these functions to automatically recur as often as your like.

To start Acer Backup Manager in Windows 8, simply start typing "Backup

Manager". Alternatively, in Desktop mode, select Acer Backup Manager.

This opens the Welcome screen; from this screen you can select the type

of backup you’d like to create.

• Back Up My Files: Select files to back up.

• Image My Drive: Create a backup file for the entire drive. You can burn

this file to a DVD, save them to another drive on your computer*, or

save them to removable media (i.e. a flash drive) to restore your

computer at a later time.

• Migrate My Files: Allows you to copy files to a USB device so that you

can migrate files from your old computer to your new one or any other

computer with Acer Backup Manager.

• Clear out / Restore Files: Remove seldom used files to free up disk

space or restore files from your backup.

Select the backup type you’d like to make and select the files or drive you

want to back up, then follow the onscreen instructions:

1. Select the content you want to back up. The less content you select, the

quicker the process will be, but it will increase your risks of losing data.

2. Select where you want the backup copies to be stored. Your options

include removable media, a drive on your computer*, CD/DVD media, a

remote PC, or the cloud using Microsoft SkyDrive.

Once you have finished these three steps, backups will be created

according to the schedule.

*NOTE: You will need to select an external drive or your D: drive; Acer

Backup Manager cannot store a backup on the source drive.

If you wish to change your settings at any time, go to the Acer Backup

Manager profiles screen. To get there from the Acer Backup Manager

welcome screen, click Launch My Backup Profiles.

From here you can edit or delete existing backup profiles.

Power management

This computer has a built-in power management unit that monitors system

activity. System activity refers to any activity involving one or more of the

following devices: keyboard, mouse, hard disk, peripherals connected to

the computer, and video memory. If no activity is detected for a period of

time, the computer stops some or all of these devices in order to conserve

energy.

Saving power

Disable Fast startup

Your computer uses Fast startup to start quickly, but also uses a small

amount of power to check for signals to start. These checks will slowly

drain your computer’s battery.

If you prefer to reduce your computer’s power requirements and

environmental impact, turn off Fast startup:

Note: If Fast startup is off, your computer will take longer to start from

Sleep. If your computer features Acer Instant On or Acer Always

Connect, these will also be turned off.

Your computer will also not start if it receives an instruction to start

over a network (Wake on LAN).

1. Open the Desktop.

2. Click Power Options in the Notification area.

3. Select More Power Options.

4. Select Choose what the power buttons do.

Battery pack

The computer uses a battery pack that gives you long use between

charges.

Battery pack characteristics

The battery pack has the following characteristics:

• Employs current battery technology standards.

• Delivers a battery-low warning.

The battery is recharged whenever you connect the computer to the AC

adapter. Your computer supports charge-in-use, enabling you to recharge

the battery while you continue to operate the computer. However,

recharging with the computer turned off results in a significantly faster

charge time.

The battery will come in handy when you travel or during a power failure. It

is advisable to have an extra fully charged battery pack available as

backup. Contact your dealer for details on ordering a spare battery pack.

Charging the battery

To charge the battery, first make sure that it is correctly installed in the

battery bay. Plug the AC adapter into the computer, and connect to a

mains power outlet. You can continue to operate your computer on AC

power while your battery is charging. However, charging the battery with

the computer turned off results in a significantly faster charge time.

Note: You are advised to charge the battery before retiring for the day.

Charging the battery overnight before traveling enables you to start

the next day with a fully charged battery.

Conditioning a new battery pack

Before you use a battery pack for the first time, there is a conditioning

process that you should follow:

1. Insert the new battery without turning the computer on.

2. Connect the AC adapter and fully charge the battery.

3. Disconnect the AC adapter.

4. Turn on the computer and operate using battery power.

5. Fully deplete the battery until the battery-low warning appears.

6. Reconnect the AC adapter and fully charge the battery again.

34

Battery pack

Follow these steps again until the battery has been charged and

discharged three times.

Use this conditioning process for all new batteries, or if a battery hasn't

been used for a long time. If the computer is to be stored for more than

two weeks, you are advised to remove the battery pack from the unit.

Warning! Do not expose battery packs to temperatures below 0°

C (32° F) or above 45° C (113° F). Extreme temperatures may

adversely affect the battery pack.

By following the battery conditioning process you condition your battery to

accept the maximum possible charge. Failure to follow this procedure will

prevent you from obtaining the maximum battery charge, and will also

shorten the effective lifespan of the battery.

In addition, the useful lifespan of the battery is adversely affected by the

following usage patterns:

• Using the computer on constant AC power with the battery inserted. If

you want to use constant AC power, you are advised to remove the

battery pack after it is fully charged.

• Not discharging and recharging the battery to its extremes, as described

above.

• Frequent use; the more you use the battery, the faster it will reach the

end of its effective life. A standard computer battery has a life span of

about 300 charges.

Optimizing battery life

Optimizing battery life helps you get the most out of battery operation,

prolonging the charge/recharge cycle and improving recharging efficiency.

You are advised to follow the suggestions set out below:

• Purchase an extra battery pack.

• Use AC power whenever possible, reserving battery for on-the-go use.

• Eject a PC Card if it is not being used, as it will continue to draw power

(for selected models).

• Store the battery pack in a cool, dry place. The recommended

temperature is 10° C (50° F) to 30° C (86° F). Higher temperatures

cause the battery to self-discharge faster.

• Excessive recharging decreases the battery life.

• Look after your AC adapter and battery.

35

Checking the battery level

The Windows power meter indicates the current battery level. Rest the

cursor over the battery/power icon on the taskbar to see the battery's

present charge level.

Battery-low warning

When using battery power pay attention to the Windows power meter.

Warning! Connect the AC adapter as soon as possible after the

battery-low warning appears. Data will be lost if the battery to

become fully depleted and the computer shuts down.

When the battery-low warning appears, the recommended course of

action depends on your situation:
