Recovering your system (USB flash

drive)

If calling Acer support did not help fix your problem, you can use the Acer

eRecovery Management program. This will restore your computer to the same

state as when you purchased it, while giving you an option to retain all settings

and personal data for later retrieval.

To recover your system

1 Perform minor fixes.

If only one or two items of software or hardware have stopped working

correctly, the problem may be solved by reinstalling the software or the device

drivers. To recover software and drivers that were pre-installed at the factory,

see

"Recovering pre-installed software and drivers" on page 21. For instructions

on reinstalling software and drivers that were not pre-installed, see that

product’s documentation or technical support Web site.

2 Revert to a previous system condition.

If reinstalling software or drivers does not help, then the problem may be

solved by returning your system to a previous state when everything was

working correctly. For instructions, see

"Returning to a previous system

condition" on page 22.

3 Reset your system to its factory condition.

If nothing else has solved the problem and you want to reset your system to

factory condition, see

"Returning your system to its factory condition" on page

23.

Types of recovery

Recovering pre-installed software and drivers

As a troubleshooting step, you may need to reinstall the software and device

drivers that came pre-installed on your computer from the factory. You can

recover using either your hard drive or the backup you have created.

New software: If you need to recover software that did not come pre-

installed on your computer, you need to follow that software’s installation

instructions.

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.

Maximizing the battery’s life

Like all other batteries, your computer's battery will degrade over time. This

means that the battery's performance will diminish with time and use. To

maximize your battery's life, you are advised to adhere to the recommendations

set out below.

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.

28

English

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.

Installing and removing the battery pack

Important! Before removing the battery from the unit, connect

the AC adapter if you want to continue using your computer.

Otherwise, turn off the computer first.

To install a battery pack:

1 Align the battery with the open battery bay; make sure that the end with

the contacts will enter first, and that the top surface of the battery is

facing up.

2 Slide the battery into the battery bay and gently push until the battery

locks in place.

29

English

To remove a battery pack:

1 Slide the battery release latch to release the battery.

2 Pull the battery from the battery bay.

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.

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.

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.

Battery-low warning

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

30

English

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:
