RECOVERY
If you are having trouble with your computer, and the frequently asked
questions do not help, you can 'recover' your computer - i.e. return it
to an earlier state.
This section describes the recovery tools available on your computer.
Acer provides Acer Recovery Management, which allows you to
create a recovery backup, a drivers and applications backup, and to
start recovery options, either using Windows tools, or the recovery
backup.
Creating a recovery backup
To reinstall from a USB storage drive, you must first create a recovery
backup. The recovery backup includes the entire original contents of
your computer’s hard drive, including Windows and all factory-loaded
software and drivers. Using this backup 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.
Note
Acer Recovery Management is only available with a pre-installed Windows
operating system.
Important
We recommend that you create a Recovery Backup and Drivers and
Applications Backup and as soon as possible. In certain situations a
full recovery will require a USB recovery backup.
Note
Make sure you have a USB drive with a capacity of at least 16 GB.
14 - Recovery
1. Open the Search charm and type 'Recovery' and then click Acer
Recovery Management in the list of apps.
2. Click Create Factory Default Backup. The Recovery Drive window
opens.
Make sure Copy contents from the recovery partition to the
recovery drive is selected. This provides the most complete and
safest recovery backup.
3. Plug in the USB drive then click Next.
Make sure your USB drive has enough capacity before
continuing. The recovery backup requires at least 16 GB of
storage
4. You will be shown the backup progress on the screen.
Recovery - 15
5. Follow the process until it completes.
6. After creating the recovery backup, you can choose to delete the
recovery information on your computer. If you delete this
information, you can only use the USB recovery backup to restore
your computer, if you lose or erase the USB drive, you cannot
restore your computer.
7. Unplug the USB drive and label it clearly.
Creating a drivers and applications backup
To create a Drivers and Applications Backup, that contains the
factory-loaded software and drivers needed by your computer, you
may use either a USB storage drive or, if you have an external DVD
recorder, one or more blank recordable DVDs.
1. From Start, type 'Recovery' and then click Acer Recovery
Management in the list of apps.
2. Click Create Drivers and Applications Backup.
Plug in the USB drive or insert a blank DVD into the optical drive, then
click Next.
Important
Write a unique, descriptive label on the backup, such as 'Windows
Recovery Backup'. Make sure you keep the backup in a safe place that
you will remember.
16 - Recovery
If you are using a USB drive, make sure your USB drive has
enough capacity before continuing.
If using DVDs, it will also show the number of blank, recordable
discs you will need to complete the recovery discs. Make sure that
you have the required number of identical, blank discs.
3. Click Start to copy files.You will be shown the backup progress on
the screen.
4. Follow the process until it completes:
If you are using optical discs, the drive ejects each disc as it
completes burning it. Remove the disc from the drive and mark it
with a permanent marker.
If multiple discs are required, insert a new disc when prompted,
then click OK. Continue until the process is complete.
If you are using a USB drive, unplug the drive and label it clearly.
Important
Write a unique, descriptive label on each backup, such as 'Drivers and
Applications Backup'. Make sure you keep the backup in a safe place
that you will remember.

Recovering your system
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 reinstall software and drivers that were pre-installed at the
factory, see Reinstalling drivers and applications on page 17.
For instructions on reinstalling software and drivers that were not
pre-installed, see that product’s documentation or 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 an earlier system snapshot on
page 19.
3. Reset your operating system.
If nothing else has solved the problem and you want to reset your
system, but keep your user information, see Returning your
system to its factory condition on page 19.
4. 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 19.
Reinstalling drivers and applications
As a troubleshooting step, you may need to reinstall the applications
and device drivers that came pre-installed on your computer from the
factory. You can reinstall using either your hard drive or the backup
you have created.
Other applications - If you need to reinstall software that did not
come pre-installed on your computer, you need to follow that
software’s installation instructions.
New device drivers - If you need to reinstall device drivers that did
not come pre-installed on your computer, follow the instructions
provided with the device.
18 - Recovery
If you are reinstalling using Windows and the recovery
information stored on your computer:
•From Start, type 'Recovery' and then click Acer Recovery
Management in the list of apps.
•Click Reinstall Drivers or Applications.

Recovery - 19
Returning to an earlier system snapshot
Microsoft System Restore periodically takes a 'snapshot' of your
system settings and saves them as restore points. In most cases of
hard-to-resolve software problems, you can return to one of these
restore points to get your system running again.
Windows automatically creates an additional restore point each day,
and also each time you install software or device drivers.
Returning to a restore point
1. From Start, type 'Control Panel' and then click Control Panel in the
list of apps.
2. Click System and Security > Action Center, then click Recovery
at the bottom of the window.
3. Click Open System Restore, then Next.
4. Click the latest restore point (at a time when your system worked
correctly), click Next, then Finish.
5. A confirmation window appears; click Yes. Your system is restored
using the restore point you specified. This process may take several
minutes, and may restart your computer.
Returning your system to its factory condition
If your computer experiences problems that are not recoverable by
other methods, you may need to reinstall everything to return your
system to its factory condition. You can recover from either your hard
drive or the recovery backup you have created.
If you can still run Windows and have the system recovery DVDs
that came with your computer, see Recovering your system on
page 23.
If you can still run Windows and have not deleted the recovery
partition, see Recovering from Windows on page 20.
Note

Using wireless devices while flying in aircraft may be prohibited. All
wireless devices must be switched off before boarding an aircraft and
during take-off, as they may be dangerous to the operation of the
aircraft, disrupt communications, and even be illegal. You may turn on
your computer’s wireless devices only when informed that it is safe to
do so by the cabin crew.
Note
Please refer to your Internet Service Provider (ISP) or router documentation
for details on connecting to the Internet.
Using a Bluetooth connection - 25
USING A BLUETOOTH CONNECTION
Bluetooth is a technology enabling you to transfer data wirelessly over
short distances between many different types of devices. Bluetooth-
enabled devices include computers, cell phones, tablets, wireless
headsets, and keyboards.
To use Bluetooth, you must ensure the following:
1. Bluetooth is enabled on both devices.
2. Your devices are "paired" (or connected).
Enabling and disabling Bluetooth
The Bluetooth adapter must be enabled on both devices.
Enable Bluetooth and add a device
Every new device must first be "paired" with your computer’s
Bluetooth adapter. This means it must first be authenticated for
security purposes. You only need to pair once. After that, simply
turning on the Bluetooth adapter of both devices will connect them.
Bluetooth on your computer is disabled by default. To enable your
computer’s Bluetooth adapter, do the following:
1. Open the Charms and select Settings > Change PC Settings > PC
and devices > Bluetooth.
2. Tap the toggle next to Bluetooth to enable/disable it.
3. Your computer will automatically start searching for devices, as well
as make itself visible to other devices.
Note
Please check your devices owner’s manual to determine how to turn on its
Bluetooth adapter.
26 - Using a Bluetooth connection
4. Tap the device you wish to add from the list of discovered devices,
and tap Pair.
A code displays on your computer, which should match the code
displayed on your device. Select Yes. Then, accept the pairing from
your device.
Note
Some devices using older versions of the Bluetooth technology require both
devices to enter a PIN. In the case of one of the devices not having any inputs
(as in a headset), the passcode is hardcoded into the device (usually "0000"
or "1234"). Consult your device’s user manual for more information.

SECURING YOUR COMPUTER
Your computer is a valuable investment that you need to take care of.
Learn how to protect and take care of your computer.
Using passwords
Passwords protect your computer from unauthorized access. Setting
these passwords creates several different levels of protection for your
computer and data:
Supervisor Password prevents unauthorized entry into the BIOS
utility. Once set, you must enter this password to gain access to the
BIOS utility. See Setting passwords on page 57.
User Password secures your computer against unauthorized use.
Combine the use of this password with password checkpoints on
boot-up and resume from Hibernation (if available) for maximum
security.
Password on Boot secures your computer against unauthorized
use. Combine the use of this password with password checkpoints
on boot-up and resume from Hibernation (if available) for maximum
security.
Entering passwords
When a password is set, a password prompt appears in the center of
the display screen.
When the Supervisor Password is set, a prompt appears when you
enter the BIOS utility.
Type the Supervisor Password and press <Enter> to access the
BIOS utility. If you enter the password incorrectly, a warning
message appears. Try again and press <Enter>.
When the User Password is set and the password on boot
parameter is enabled, a prompt appears at boot-up.
Important
Do not forget your Supervisor Password! If you forget your password,
please get in touch with your dealer or an authorized service center.
Securing your computer - 29
Type the User Password and press <Enter> to use the computer. If
you enter the password incorrectly, a warning message appears. Try
again and press <Enter>.
Important
You have three chances to enter a password. If you fail to enter the
password correctly after three tries, the system halts. Press and hold
the power button for four seconds to shut down the computer. Then
turn on the computer again, and try again.
30 - Battery pack
BATTERY PACK
The computer uses an embedded Lithium battery that gives you long
use between charges.
Battery characteristics
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 significantly
reduces charge time.
The battery will come in handy when you travel or during a power
failure.
Charging the battery
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 significantly reduces charge time.
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. Connect the AC adapter and fully charge the battery.
2. Turn on the computer and complete setting up the operating system.
3. Disconnect the AC adapter.
4. Operate the computer using battery power.
5. Reconnect the AC adapter and fully charge the battery again.
Follow these steps again until the battery has been charged and
discharged three times.
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.
Battery pack - 31
Use this conditioning process for all new batteries, or if a battery
hasn't been used for a long time.
The battery conditioning process ensures your battery accepts 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.
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. An embedded battery has a life span of
more than 1,000 charge/discharge cycles.
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:
Use AC power whenever possible, reserving battery for mobile use.
Remove accessories that are not being used (e.g. a USB disk
drive), as they can continue to draw power.
Store your PC 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.
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.
32 - Battery pack
Checking the battery level
The 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 power meter.
When the battery-low warning appears, the recommended course of
action depends on your situation:
Important
Connect the AC adapter as soon as possible after the battery-low
warning appears. Data may be lost if the battery is allowed to become
fully depleted and the computer shuts down.
Situation Recommended Action
The AC adapter
and a power
outlet are
available.
1. Plug the AC adapter into the computer, and
then connect to the main power supply.
2. Save all necessary files.
3. Resume work.
Turn off the computer if you want to recharge
the battery rapidly.
The AC adapter
or a power outlet
is unavailable.
1. Save all necessary files.
2. Close all applications.
3. Turn off the computer.
