Part 2 Troubleshooting • Power-On Self-Test • OmniBook Diagnostics • Desktop Management Interface • System Configuration Utility • Troubleshooting Tips.
4 Power-On Self- Test The OmniBook 800 BIOS includes a Power-On Self-Test (POST) facility that tests a number of hardware and firmware items in the unit at each cold-start (BOOT or RESET). The OmniBook self-test alone should not be used to diagnose a hardware problem.
5 Display Codes There are a number of Power On Self Test (POST) tests that are performed after the Beep Code tests. Failure of one or more of these tests will result in a displayed failure code (such as 03044). It is extremely important not to interpret a failure code immediately as a hardware failure.
6 Message Possible Cause KEYBOARD FAILURE The keyboard failed to respond to the RESET ID Command. MACHINE IS LOCKED - TURN KEY The system will not continue the boot sequence until you insert the key into the key lock and turn it. NO BOOTABLE FLOPPY DRIVE 0 INSTALLED No bootable floppy drive was detected.
7 OmniBook Diagnostics The OmniBook diagnostics program provides an effective tool for diagnosing and isolating a hardware problem. The diagnostics software is intended for use in concert with additional troubleshooting methods to accurately determine the cause of trouble.
8 Figure 4 - Main Diagnostic Screen Running selected tests Tests may be initiated individually, or as a group. Some tests may be run at different levels. In general, tests that can take a long time to be fully checked have levels that permit testing more quickly while still providing a reasonable level of testing.
9 The name of the currently selected test is always shown inversed. To help monitor the progress of testing, the LEDs (near the On button) blink about once per second from green to off. If a test has failed the LEDs blink from red to off. When Diag finishes testing, the LEDs blink rapidly.
10 Loop Back Connectors In order to run the RS232 serial port, parallel port, and SCSI port self-test, a loop back connector is needed. The loop back may be placed on either the OmniBook port or at the end of the corresponding cable. This feature is also helpful in diagnosing a defective serial, parallel, or SCSI cable.
11 PCMCIA Type III extender card The PCMCIA test that makes use of SyCard Technology’s SyCard also requires an extender card modified with two jumpers or with solder bridges. In order for the Sycard to be detected, CD1- and GND must be shorted together, and GND with CD2- must also be shorted together.
12 Command line options When Diag is run, either from the command line, or from a batch file, a number of switches (or options) may be included to “customize” the operation of Diag. Switches must be specified separately, and must begin with either a - or a / character.
13 Also some key caps have characters that cannot be displayed with the text characters available. Therefore, when running the keyboard test on a foreign keyboard, the POSITION of the key within the k.
14 upon exit (no reboot necessary in most cases). Alt+F12 Dump the text screen to a file named DIAG.xxx where xxx begins at 000 and increases by one each time another screen dump is captured. Screen dumps from previous runs of Diag are preserved. ? or F1 Display a help screen of keyboard commands.
15 Top Bumper <Up> Highlight previous test. Bottom Bumper <Down> Highlight next test. Left Button <Enter> Run current or selected tests. Right Button <Space> Mark highlighted test. Right Bumper <Backspace> Cancel currently running test.
16 Alt+E + Alt+V Set the Vertical lost calibration speed thresholds used in the graphic draw mouse test. The defaults limits are 200 to 400. Alt+E + Alt+M Set mouse bumper failure threshold. The default number of mickeys for this is 1000. The number reflects how much bumper compression is permitted before a bumper is rejected.
17 Alt+C Set Contrast 0-255. Systems with a DSTN display can specify a display contrast from 0 to 255. This exceeds the normal range permitted with the contrast buttons and can result in a blank display. Repeat the command with a less extreme value to restore the display.
18 operation of all tests depend on the presence or absence of XMS or EMS drivers. In general, if there is no XMS and no EMS driver, then memory will be accessed directly in pseudo-32-bit mode (i.e. with 4 GB selectors but from real code), if there is an XMS/EMS driver, the XMS driver will be used to access memory.
19 Figure 9 - Sycard Test Results The OmniBook model F1360 supports zoom video and Cardbus. If a Sycard model 450 PCMCIA socket tester is found (in the upper slot only), a zoom video test will be run on that slot. Lower PC Card Level: 2. This test operates like the upper PC card test, but for the lower slot.
20 received is echoed back to the host. The IR port is first tested in slow mode by sending / receiving data packets at 115K baud. If this passes, then data packets are transmitted in high speed at 1 megabit then 4 megabit. These IR transmission tests are repeated 3 times.
21 Keyboard Levels: 1,2. The level 1 keyboard test checks that the keyboard responds appropriately to commands sent from the CPU. The level 2 keyboard test also checks that each key functions properly. The level 2 test passes when each key has been pressed or aborts if the <Space> or <Esc> key is pressed three times in a row.
22 the mouse position to change. Press both buttons and move the mouse in all directions, then press a key again to exit the test. This will end the text mode mouse test. IMPORTANT NOTE ON THE USE OF BOTH BUTTONS: any time both buttons are pressed down, a release of just one button will NOT be recognized.
23 Figure 11 - Mouse Test Screen (text mode) Graphic mode mouse sine test This mouse test is used to measure the maximum “sine effect” of the mouse.
24 Figure 12 - Mouse Test Screen (graphics mode) As the prompt indicates, to run this test, you must move the mouse to the corner where the white box is displayed (initially the top right corner). When you activate BOTH bumpers at that corner, the white box moves counterclockwise to the next corner.
25 BotEdgeErr indicates the maximum total sine error along the bottom edge. When the two cycles are complete, the maximum of the top and bottom errors is compared against a test threshold. If above, the test fails, else the test passes. The default threshold is 10 pixels.
26 Audio Level: 2. This test checks the SoundBlaster compatible audio sound system. The DSP chip, DMA Channel, and Interrupt Lines are checked for proper operation. An audible sound test completes the test; a bong sound alternating between left and right speakers should be heard.
27 Dock keyboard Levels: 1,2. This test operates like the Keyboard test except that it uses a standard 101 key keyboard connected to the dock. The display shown during this test mirrors the layout of a standard 101 key keyboard. Its operation is similar to the internal keyboard test, but for an external keyboard.
28 Desktop Management Interface (DMI) The Desktop Management Task Force (DMTF) was founded in 1992 by a group of leading computer manufacturers, including Hewlett-Packard, to define a standard method of managing the physical and logical components of personal computers.
29 The following software is supplied with the DMI package: • A Microsoft Windows utility, SETUP.EXE, to install and initialize the DMI software. • A Windows utility, HP TopTools. After DMI is installed, this utility can be used to display information about the computer through the DMI.
30 Installing the DMI Package from Windows 95 The DMI package is included with the OmniBook, but it must be properly installed before it can be used. The following steps explain how. To install the DMI preloaded on the hard disk: • Start Windows 95, if it is not already running.
31 Setup and Configuration The System Configuration Utility (SCU) is an operating system independent pop-up program. It can only be accessed at boot-time by pressing F2.
