HP Pavilion 11 E100 Notebook Pc Series User Manual

							display brightness decreases to conserve battery life. The battery in the computer slowly discharges
when the computer is off and unplugged from external power.
Computer battery life varies, depending on power management settings, programs running on the
computer, display brightness, external devices connected to the computer, and other factors.
Removing a user-replaceable battery
WARNING!To reduce potential safety issues, use only the user-replaceable battery provided with
the computer, a replacement battery provided by HP, or a compatible battery purchased from HP.
CAUTION:Removing a user-replaceable battery that is the sole power source for the computer can
cause loss of information. To prevent loss of information, save your work or shut down the computer
through Windows before removing the battery.
1.Slide the battery lock latch (1), and then slide the battery release latch (2) to release the battery.
2.Remove the battery (3) from the computer.
Finding battery information
To monitor the status of your battery, or if the battery is no longer holding a charge, run Battery Check
in HP Support Assistant. To access battery information, from the Start screen, type support, select
the HP Support Assistant app, and then select Battery and performance.
HP Support Assistant provides the following tools and information about the battery:

adapter to the computer and to external power.
2.Exit Hibernation by pressing the power button.
Storing a user-replaceable battery
CAUTION:To reduce the risk of damage to a battery, do not expose it to high temperatures for
extended periods of time.
If a computer will be unused and unplugged from external power for more than 2 weeks, remove the
battery and store it separately in a cool, dry place to prolong the battery charge.
A stored battery should be checked every 6 months. If the capacity is less than 50 percent, recharge
the battery before returning it to storage.
Disposing of a user-replaceable battery
WARNING!To reduce the risk of fire or burns, do not disassemble, crush, or puncture; do not short
external contacts; do not dispose of in fire or water.
See the Regulatory, Safety and Environmental Notices for proper battery disposal. To access this
guide, from the Start screen, type support, select the HP Support Assistant app, select My
computer, and then select User guides.
Replacing a user-replaceable battery
Battery Check in HP Support Assistant notifies you to replace the battery when an internal cell is not
charging properly or when the battery storage capacity has reached a weak condition. If the battery is
possibly covered by an HP warranty, instructions include a warranty ID. A message refers you to the
HP website for more information about ordering a replacement battery.
Running on external AC power
For information on connecting to AC power, refer to the Setup Instructions poster provided in the
computer box.
The computer does not use battery power when the computer is connected to AC external power with
an approved AC adapter or an optional docking/expansion device.
WARNING!To reduce potential safety issues, use only the AC adapter provided with the computer,
a replacement AC adapter provided by HP, or a compatible AC adapter purchased from HP.

							7 Managing and sharing information
Drives are digital storage devices that help you store, manage, share, and access information. Your
computer has an internal hard drive or a solid state drive that stores your computers software,
operating system, and also provides storage for all of your personal files. Some computers have a
built-in optical drive that allows you to read or write to a CD, DVD, or (on select models) Blu-ray Disc
(BD).
For added capacity or functionality, connect an external drive (purchased separately), such as an
optical drive or hard drive, or insert a memory card directly from your phone or camera. A Universal
Serial Bus (USB) flash drive, connected to the USB port on your computer, also allows quick data
transfer. Some devices use the computers power to run; others have their own power source. Some
devices come with software that must be installed.
NOTE:For information about connecting external wireless devices, see Connecting to a network
on page 15.
NOTE:For more information about required software and drivers, or to learn which computer port to
use, see the manufacturers instructions.
Using a USB device
Most computers have more than one USB port, because this versatile interface allows you to connect
numerous kinds of external devices—such as a USB keyboard, mouse, external drive, printer,
scanner, or USB hub—to your computer.
Your computer has more than one type of USB port. See 
Getting to know your computer on page 4
for the types of USB ports you have on this computer. Be sure to purchase devices that are
compatible with your computer.
Type Description
USB 2.0 Transfers data at 60 MB/s.
USB 3.0 Transfers data at 640 MB/s. USB 3.0 ports, also known as
SuperSpeed ports, are also compatible with USB 1.0 and 2.0
devices.
Connecting a USB device
CAUTION:To reduce the risk of damage to a USB connector, use minimal force to connect the
device.

							8 Maintaining your computer
It is important to perform regular maintenance to keep your computer in optimal condition. This
chapter provides information about improving the performance of your computer by running tools
such as Disk Defragmenter and Disk Cleanup. It also provides information about updating your
programs and drivers, instructions for cleaning your computer, and tips for traveling with your
computer.
Improving performance
Everyone wants a fast computer and by performing regular maintenance tasks, using tools such as
Disk Defragmenter and Disk Cleanup, you can drastically improve the performance of your computer.
Also, as your computer gets older, you might consider installing larger drives and adding more
memory.
Handling drives
Observe these precautions when handling drives:
●Before removing or installing a drive, shut down the computer. If you are unsure whether the
computer is off, in the Sleep state, or in Hibernation, turn the computer on, and then shut it down
through the operating system.
●Before handling a drive, discharge static electricity by touching the unpainted metal surface of
the drive.
●Do not touch the connector pins on a removable drive or on the computer.
●Do not use excessive force when inserting a drive into a drive bay.
●When the battery is the only source of power, be sure that the battery is sufficiently charged
before writing to media.
●If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective
packaging and label the package “FRAGILE.”
●Avoid exposing a drive to magnetic fields. Security devices with magnetic fields include airport
walk-through devices and security wands. Airport conveyer belts and similar security devices
that check carry-on baggage use X-rays instead of magnetism and do not damage drives.
●Remove media from a drive before removing the drive from the drive bay, or traveling with,
shipping, or storing a drive.
●Do not type on the keyboard or move the computer while an optical drive is writing to a disc. The
write process is sensitive to vibration.
●Before you move a computer that is connected to an external hard drive, initiate Sleep and allow
the screen to clear, or properly disconnect the external hard drive.
Replacing a hard drive
CAUTION:Drives are fragile computer components that must be handled with care. Do not drop a
drive, place items on it, or expose it to liquids, or temperature or humidity extremes. See 
Handling
drives on page 49 for specific precautions when handling drives.

							CAUTION:To prevent information loss or an unresponsive system:
Before removing or installing a drive, shut down the computer. If you are unsure whether the
computer is off, in the Sleep state, or in Hibernation, turn the computer on, and then shut it down
through the operating system.
Before you remove the hard drive:
1.Save your work and shut down the computer.
2.Disconnect all external devices connected to the computer.
3.Unplug the power cord from the AC outlet.
4.Turn the computer upside down on a flat surface.
5.Remove the battery from the computer (see 
Removing a user-replaceable battery on page 41).
Remove the hard drive:
1.Lift up and remove the service door.
2.Disconnect the hard drive cable (1) from the computer.
NOTE:To help prevent damage to the hard drive cable, the cable runs underneath the hard
drive cable covering (2).
