Maintaining your computer

It is important to perform regular maintenance to keep your computer in optimal condition. This chapter 

explains how to use tools like Disk Defragmenter and Disk Cleanup. It also provides instructions for updating 

programs and drivers, steps to clean the computer, and tips for traveling with (or shipping) the computer.

Improving performance

You can improve the performance of your computer by performing regular maintenance tasks with tools such 

as Disk Defragmenter and Disk Cleanup.

Using Disk Defragmenter

HP recommends using Disk Defragmenter to defragment your hard drive at least once a month.

NOTE:

It is not necessary to run Disk Defragmenter on solid-state drives.

To run Disk Defragmenter:

1.

Connect the computer to AC power.

2.

Type 

defragment

 in the taskbar search box, and then select Defragment and Optimize Drives.

3.

Follow the on-screen instructions.

For additional information, access the Disk Defragmenter software Help.

Using Disk Cleanup

Use Disk Cleanup to search the hard drive for unnecessary files that you can safely delete to free up disk space 

and help the computer run more efficiently.
To run Disk Cleanup:

1.

Type 

disk

 in the taskbar search box, and then select Disk Cleanup.

2.

Follow the on-screen instructions.

Updating programs and drivers

HP recommends that you update your programs and drivers on a regular basis. Updates can resolve issues 

and bring new features and options to your computer. 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.
Go to 

http://www.hp.com/support

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

register to receive automatic notifications when updates become available.
If you would like to update your programs and drivers, follow these instructions:

1.

Type 

support

 in the taskbar search box, and then select the HP Support Assistant app.
