Product Description

The HP Compaq Thin Client products may either be HP ThinConnect-based or Windows-based terminals

that connect over a network to a server where all processing and storage occurs. Because of the nature

of the products, troubleshooting is significantly simpler than on a standard PC and previous thin clients.

The Graphical User Interface is English on all thin clients. If you are using a foreign language keyboard,

you will need to set localized settings to perform the localization between a server-based application and

the device, but interaction with the unit itself remains in English.

Operating Systems

The HP ThinConnect operating system on the t51x5 models is a very basic system designed to support

the thin client's role as a connection appliance. It is simple to use and is a very effective connection device

for RDP and ICA connections

The Windows CE operating system used on the 55xxx models supports the new VIA chipsets and

processors, the latest Microsoft QFE (Quick Fix Engineering) patches, new DHCP option support, as well

as FTP and SMB update capabilities. A Windows CE version of the HP Thin Tools image capture utility is

included in the image to allow the user to capture a customized image and produce a ready-for-

deployment package for distribution.

Connecting USB Equipment

USB mouse devices and keyboards do not require special drivers and are considered to be plug and play

peripherals. Certain USB devices such as printers and modems, however, may require special drivers.

For information on requirements for special drivers, refer to the documentation that is included with the

USB device.

BIOS Settings, (F10) Utility

Using the BIOS Settings

The VIA C7 processors and the CN700 chipset used in the t5135 and t5530 products are supported by

a Phoenix Award BIOS.

Changing BIOS Settings from within the operating system

Some BIOS settings may be changed locally within the operating system without having to go through the

F10 utility

1

. This table identifies the items that can be controlled with this method.

BIOS Setting Default Value Other Values

1st Boot Device USB ATA Flash, Network, Disabled

2nd Boot Device ATA Flash USB, Network, Disabled

3rd Boot Device Network ATA Flash, USB, Disabled

Boot Up NumLock Off On

F12 Boot Enabled Disabled

NOTE:

1

Settings that can be controlled from the operating system with repset can also be controlled

remotely by sending the client an Altiris job that uses the repset tool to apply the setting changes.

2

For Win CE, displays only Enabled or Disabled status IO Base and IRQ cannot be changed. Enabled is

the same as setting the base/IRQ to 378/IRQ4.

ENWW Using the BIOS Settings 5

Changing BIOS Settings Using the F10 Utility

1.

Turn on or restart the thin client.

2.

As soon as the thin client is turned on, press F10 when the monitor light turns green to enter the Setup

Utility.

NOTE: If you do not press F10 at the appropriate time, you must restart the thin client and again

press F10 when the F10=Setup message displays in the task bar at the bottom of the screen. When

the F10 POST Screen display is set to zero seconds, it may be necessary to press and hold F10 on

the keyboard, then power on the thin client.

3.

The Setup Utility screen is divided into five menu headings and five task actions.

The Menu Headings are:

●

System Information

●

Standard CMOS Features

●

Advanced BIOS Features

●

Integrated Peripherals

●

Power Management Setup

The Task Actions are:

●

Load Factory Defaults

●

Set Administrative Password

●

Set User Password

●

Save & Exit Setup

●

Exit without Saving

Use the arrow keys (up and down or left and right) to select the appropriate heading, then press

Enter. To return to the Setup Utility menu, press Esc key.

4. To apply and save changes, select Exit Setup & Save.

If you have made changes that you do not want applied, select Exit without Saving.

To reset to original factory settings, select Load Factory Defaults.

CAUTION: Do NOT turn the thin client power Off while the ROM is saving the Setup (F10) changes

because the CMOS could become corrupted. It is safe to turn off the computer only after exiting the F10

Setup screen.

back up the settings before a recovery is needed.

The CMOS Save/Load utility can be found at

http://www.hp.com under the Software & Driver

Downloads for your specific model. Download the firmware files into a folder on a removable storage

device. It is recommended that you save any modified computer configuration settings to a diskette, a USB

flash media device, or a diskette-like device (a storage device set to emulate a diskette drive) and save

the diskette or device for possible future use.

Backing Up the CMOS

1.

Make sure the computer to be backed up is turned on. Connect the removable storage to the

computer.

2.

Boot to DOS.

3.

Type N:\folder\BIOS.exe SAVE:ABC001.DAT (where N is the drive letter of the removable

storage) to save the CMOS setting to the removable storage device.

10 Chapter 2 BIOS Settings, (F10) Utility ENWW

Restoring the CMOS

1.

Make sure the target computer is turned on. Connect the removable storage to the target computer.

2.

Boot to DOS.

3.

Diagnostics and Troubleshooting

LEDs

Table 3-1 Power and IDE Flash Activity LEDs

LED Status

Power LED Off When the unit is plugged into the wall socket and the Power LED is off, the unit is powered off.

However, the network can trigger a Wake On LAN event in order to perform management functions.

Power LED On Displays during boot sequence and while the unit is on. During boot sequence, hardware

initialization is processed and startup tests are performed on the following:

●

Processor initialization

●

Memory detection and initialization

●

Video detection and initialization

NOTE: If one of the tests fails, the unit will simply stop, but the LED will stay on. If the video test

fails, the unit beeps. There are no messages sent to video for any of these failed tests.

NOTE: After the video is initialized, anything that fails will have an error message.

NOTE: RJ-45 LEDs are located inside the RJ-45 connector on the top, rear panel of the thin client. The LEDs are visible when the

connector is installed. Blinking green indicates network activity, and amber indicates a 100MB speed connection.

IDE LED is Off

When the unit is powered on and the flash activity light is off, then there is no access to the system

flash.

IDE LED blinks Green Indicates the system is accessing the internal IDE flash.

ENWW LEDs 13

Power-On Sequence

At power-on, the flash boot block code initializes the hardware to a known state, then performs basic

power-on diagnostic tests to determine the integrity of the hardware. Initialization performs the following

functions:

1.

Initializes CPU and memory controller.

2.

Initializes VGA software.

3.

Initializes and configures all PCI devices.

4.

Initializes the video to a known state.

5.

Initializes USB devices to a known state.

6.

Performs power-on diagnostics. For more information, see “Power-On Diagnostic Tests”.

7.

The unit boots the operating system.

Power-On Diagnostic Tests

The Power-on diagnostics performs basic integrity tests of the hardware to determine its functionality and

configuration. If a diagnostic test fails during hardware initialization the unit simply stops. There are no

messages sent to video.

NOTE: You may try to restart the unit and run through the diagnostic tests a second time to confirm the

first shutdown.

The following table lists the tests that are performed on the t5000 units.

Table 3-2 Power-On Diagnostic Test

Test Description

Boot Block Checksum Tests boot block code for proper checksum value

DRAM Simple write/read pattern test of the first 640k of memory

Parallel Port Initiates the port’s driver and determines if the device is present

Serial Port Tests the serial port using simple port verification test to determine if ports are present

Timer Tests timer interrupt by using polling method

RTC CMOS battery Tests integrity of RTC CMOS battery

NAND flash device Tests for proper NAND flash device ID present
