Video Resolution Mode (for both LCD and CRT)

Battery

There are two control signals that come form system to control lamp brightness. One signal is named DAC_BRIG, which limits current to meet LCD lamp current specification. Another one is named PWM, which adjusts lamp brightness. This inverter brightness is adjusted by PWM burst mode. The PWM burst mode is that turning on and off the lamp at rate of 150Hz. The effective brightness is a function of the duty cycle.

Features

1.Wide range 9V to 21V input voltage.

2.Birghtness adjustment by PWM duty mode.

3.Close loop controls lamp current.

Electrical Characteristics

*1. The inverter can work in 7.5V input voltage (continuous), but 7.5V electronic characteristic will not be care.

*2. Limited lamp maximum current by DAC_BRIC signal:

When DAC_BRIG voltage is 0V and INV_PWM enables (100%), lamp has max. current. When DAC_BRIG voltage is 3.3V and INV_PWM enables (100%), lamp has min. current. When add 1V DAC, the 100% Lamp current will decrease 0.5mA.

DAC_BRIG signal comes from system chipset with internal resistance of 3K ???

*3. Inverter operating frequency should be within specification (45~65kHz) at max. and min. brightness load.

*4. INV_PWM enable implies INV_PWM signal is High level (On duty cycle is 100%). It is a square wave of 150Hz to adjust backlight brightness that is a function of PWM duty cycle. Backlight brightness is maximum value under INV_PWM at 100% and brightness is minimum under INV_PWM at 30%.

*5.The system interface signals belong to 3.3V.

*6. Please make sure open lamp output voltage should be within starting voltage specification. *7. Inverter should pass human body safety test.

*8. Inverter should be no smoking by any component open/short test.

*9. Transformer voltage stress should not be over 85% under any condition. (turn on overshoot transient and line transient.)

*10. Audio noise should be less than 36dB at 10cm distance.

.

Electrical specification

Thermal

If an error occurs, reconnect the connector on the main board. If the error still remains:

1.Reconnect the CD-ROM/DVD-ROM module.

2.Replace the CD-ROM/DVD-ROM module.

3.Replace the main board.

Keyboard or Auxiliary Input Device Check

Remove the external keyboard if the internal keyboard is to be tested.

If the internal keyboard does not work or an unexpected character appears, make sure that the flexible cable extending from the keyboard is correctly seated in the connector on the main board.

If the keyboard cable connection is correct, run the Keyboard Test.

If the tests detect a keyboard problem, do the following one at a time to correct the problem. Do not replace a non-defective FRU:

1.Reconnect the keyboard cables.

2.Replace the keyboard.

3.Replace the main board.

The following auxiliary input devices are supported by this computer:

!Embedded Numeric Keypad

!External keyboard

If any of these devices do not work, reconnect the cable connector and repeat the failing operation.

Memory Check

Memory errors might stop system operations, show error messages on the screen, or hang the system. Currently, we do not provide memory test program. However, if you need to check memory but have no testing program or diagonositc utility at hand, please go to http://www.passmark.com to download the shareware ???BurnIn Test V.3.0???. You may test the memory with this program under Window XP environment.

NOTE: Make sure that the DIMM is fully installed into the connector. A loose connection can cause an error.

Power System Check

To verify the symptom of the problem, power on the computer using each of the following power sources:

1.Remove the battery pack.

2.Connect the power adapter and check that power is supplied.

3.Disconnect the power adapter and install the charged battery pack; then check that power is supplied by the battery pack.

If you suspect a power problem, see the appropriate power supply check in the following list:

!???Check the Power Adapter???

!???Check the Battery Pack???

Check the Power Adapter

Unplug the power adapter cable from the computer and measure the output voltage at the plug of the power adapter cable. See the following figure

Pin 1: 19V

Pin 2: 0V, Ground

1.If the voltage is not correct, replace the power adapter.

2.If the voltage is within the range, do the following:

!Replace the main board.

!If the problem is not corrected, see ???Undetermined Problems???.

!If the voltage is not correct, go to the next step.

NOTE: An audible noise from the power adapter does not always indicate a defect.

3.If the DC-IN indicator does not light up, check the power cord of the power adapter for correct continuity and installation.

4.If the operational charge does not work, see ???Check the Power Adapter??? .

still occurs, continue next step.

Replace the CPU with another of the same specifications. If the problems still occurs, go to next step.

The main board may be damaged. Replace main board.

3.If the external monitor has the same problem as the internal monitor, the main board may be damaged. Please insert the diagnostic disk and run the display test program and go through the sub-steps under step 2.

Sound Check

To determine if the computer???s built-in speakers are functioning properly, perform the following steps. Before you start the steps below, adjust the speaker volume to an appropriate level.

1.Try different audio sources. For example, employ audio CD and ditital music file to determine whether the fault is in the speaker system or not. If not all sources have sound problem, the problem is in the source devices. If all have the same problem, continue next step.

2.Connect a set of earphone or external speakers. If these devices work fine, go to next step. If not, then the main board may be defective or damaged. Replace the main board.

3.Follow the disassembling steps in Chapter 3. Esure the speaker cable is firmly connected to the main board. If the speaker is still a malfunction, go on next step.

4.If the speakers do not sound properly, the speakers may be defective or damaged. Replace the speakers. If the problem still occurs, then replace the main board.

Insyde MobilePro BIOS POST Beep Code and POST Messages

The POST error message index lists the error message and their possible causes. The most likely cause is listed first.

NOTE: Perform the FRU replacement or actions in the sequence shown in FRU/Action column, if the FRU replacement does not solve the problem, put the original part back in the computer. Do not replace a non-defective FRU.

This index can also help you determine the next possible FRU to be replaced when servicing a computer. If the symptom is not listed, see ???Undetermined Problems??? on page 73.

The following lists the error messages that the BIOS displays on the screen and the error symptoms classified by function.

NOTE: Most of the error messages occur during POST. Some of them display information about a hardware device, e.g., the amount of memory installed. Others may indicate a problem with a device, such as the way it has been configured.

Intermittent Problems

Intermittent system hang problems can be caused by a variety of reasons that have nothing to do with a hardware defect, such as: cosmic radiation, electrostatic discharge, or software errors. FRU replacement should be considered only when a recurring problem exists.

When analyzing an intermittent problem, do the following:

1.Run the diagnostic test for several times to isolate the problem.

2.If no error is detected, do not replace any FRU.

3.If any error is detected, replace the FRU. Rerun the test to verify that there are no more errors.

Undetermined Problems

The diagnostic problems does not identify which adapter or device failed, which installed devices are incorrect, whether a short circuit is suspected, or whether the system is inoperative.

Follow these procedures to isolate the failing FRU (do not isolate non-defective FRU). NOTE: Verify that all attached devices are supported by the computer.

1.Power-off the computer.

2.Visually check them for damage. If any problems are found, replace the FRU.

3.Remove or disconnect all of the following devices:
