Maintaining your computer

Updating programs and drivers

HP recommends that you update your programs and drivers on a regular basis to the latest versions.
Updates can resolve issues and bring new features and options to your computer. Technology is
always changing, and updating programs and drivers allows your computer to run the latest
technology available. For example, older graphics components might not work well with the most
recent gaming software. Without the latest driver, you would not be getting the most out of your
equipment.

There are two ways you can obtain updates for your computer:

Go to 

http://www.hp.com/support

 to download the latest versions of HP programs and drivers. In

addition, register to receive automatic update notifications when they become available.

Set your computer to receive automatic updates.

To set your computer to receive free automatic Ubuntu updates:

1.

Click the 

System menu

 icon at the far right of the top panel, and then click 

Software up to

Date

.

2.

In the Update Manager window, click the 

Check

 button to check for new software updates.

3.

Click the box next to each update that you want to install, and then click the 

Install Updates

button.

4.

Click 

Close

 after the updates have been installed.

NOTE:

To change the settings for software updates, click the 

Settings

 button on the bottom of

the Update Manager window.

Cleaning your computer

Cleaning your computer and external devices helps keep them in good working condition. If you don't
clean your computer, dust and dirt particles can build up.

CAUTION:

Avoid using the following cleaning products to clean your computer:

Strong solvents, such as alcohol, acetone, ammonium chloride, methylene chloride, and
hydrocarbons, which can permanently damage the surface of the computer.

Cleaning the display, sides, and cover

Gently wipe the display using a soft, lint-free cloth moistened with an 

alcohol-free

 glass cleaner. Allow

the screen to dry before closing the computer cover.

Use a pre-moistened germicidal wipe to clean the sides and cover. Fibrous materials, such as paper
towels, can scratch the computer.

NOTE:

When cleaning the cover of the computer, use a circular motion to aid in removing dirt and

debris.
