and install a BIOS update only when the computer is connected to reliable external power using
the AC adapter. Do not download or install a BIOS update while the computer is running on battery
power, docked in an optional docking device, or connected to an optional power source. During
the download and installation, follow these instructions:
Do not disconnect power from the computer by unplugging the power cord from the AC outlet.
Do not shut down the computer or initiate Sleep or Hibernation.
Do not insert, remove, connect, or disconnect any device, cable, or cord.

computer. Make a note of the date, name, or other identifier. You may need this information
to locate the update later, after it has been downloaded to your hard drive.
b.Follow the on-screen instructions to download your selection to the hard drive. Make a note
of the path to the location on your hard drive where the BIOS update is downloaded. You
will need to access this path when you are ready to install the update.
NOTE:If you connect your computer to a network, consult the network administrator
before installing any software updates, especially system BIOS updates.

the update.
4.Double-click the file that has an .exe extension (for example, filename.exe).
The BIOS installation begins.
5.Complete the installation by following the on-screen instructions.
NOTE:After a message on the screen reports a successful installation, you can delete
the downloaded file from your hard drive.
Using System Diagnostics
System Diagnostics allows you to run diagnostic tests to determine if the computer hardware is
functioning properly. The following diagnostic tests are available in System Diagnostics:
●Start-up test—This test analyzes the main computer components that are required to start
the computer.
●Run-in test—This test repeats the start-up test and checks for intermittent problems that
the start-up test does not detect.
●Hard disk test—This test analyzes the physical condition of the hard drive, and then checks all
data in every sector of the hard drive. If the test detects a damaged sector, it attempts to move
the data to a good sector.
●Memory test—This test analyzes the physical condition of the memory modules. If it reports an
error, replace the memory modules immediately.
●Battery test—This test analyzes the condition of the battery. If the battery fails the test, contact
HP support to report the issue and purchase a replacement battery.
You can also view system information and error logs in the System Diagnostics window.
To start System Diagnostics:
