Beep Codes

Errors can occur during POST (Power On Self Test), which is performed every time the computer is powered on. Fatal errors (see
below) are communicated through a series of audible beeps. All errors except Beep Code 8 are fatal errors. Fatal errors do not
allow the computer to continue the boot process. Most displayed errors allow the computer to continue the boot process.

Replacing the

Battery

56

IInnsseerrttiinngg aanndd RReemmoovviinngg tthhee BBaatttteerryy PPaacckk

The battery pack should already be inserted in your Notebook computer when you unpack it. If not inserted, follow these directions:

1.

Turn over the notebook and place it on a solid, flat surface.

2.

Angle the battery into the bay. The front edge of the battery should slide into the grooves in the system case.

Gently lower the battery into the bay and push it until it clicks securely in the bay.
To remove the battery pack:

1. Turn off the notebook, and disconnect the AC adapter. Close the LCD panel and turn it
over and place it on a solid, flat surface.

2. Lift the release latch to release the battery from the bay. At this time the battery will now
be angled slightly out of the bay.

3. Hold the battery at the finger grip and lift it out of the compartment.

Upgrading your

System

58

Upgrading your Memory

Refer to the following instructions and illustration for information on upgrading your notebook's memory.

1.

Turn off the computer and disconnect the AC adapter and all peripherals.

2.

Turn the notebook over so that the rear ports are facing you and locate the memory module compartment.

3.

Remove the screws that secure the RAM module compartment cover and set it aside in a safe place.

4.

Remove the compartment cover and then angling it up and out.

5.

If you need to install a higher capacity module, gently push the edge clips on both sides to release the module.

Angle the card slightly upward and gently slide it from its edge connector slot. Store the card in the anti-static
bag that contains your new module(s).

6.

To install the new memory card, hold the card with its gold edge connector toward the edge connector slot of the

compartment. To help you orient the cards, the edge connector has been made with two unequal-length sections.
You will only be able to insert the card in one direction.

59

7.

Insert the edge connector into the slot. The gold edge connector of the card should not be visible when the card

is fully inserted.

8.

Press the card downward where you should hear an audible click as the latches of the connector secure the card

in place.

9.

Once the module is properly seated, you can replace the cover on this compartment.

10.

Replace and tighten the screw.

Easy to Upgrade HDD Module

The hard drive in your notebook computer is made to be easily swapped out for upgrading. You should back up your hard drive
before attempting o change the hard drive.
Make sure that before you install a new drive, all the files in your system should be backed up.

How to upgrade your Hard Drive

1.

Power down the system completely. Turn the system over with the front of the unit facing you.

2.

Remove the two screws that secure the compartment cover and set them in a safe place.

3.

Slide the HDD cover away from the compartment.

4.

The drive is attached to a special bracket that secures it to the notebook computer. There are 2 screws that

hold the bracket.

5.

Push the HDD slightly as shown in the illustration to release it from the pins of the drive.

6.

Gently hold the grip of the HDD, lift it up to release from its compartment.

60

7.

To install the new HDD, you will need to align the tabs on the drive bracket with the slots on the bay. Press down

gently on the drive bracket until it engages with the system. Do not force the drive into place this can bend the
pins on the hard drive.

8.

Slide the compartment cover into place and be sure the screw holes on the cover align completely with the

screw holes in the case.

9.

Secure the cover with the two screws.
