System is lit with no display does not turn on

check the memory ram

This is only the first of many things you may need to do to determine the fault. But it is a process for determining the exact cause.

Make sure the ac adapter is correctly plugged into the notebook and into the power cord.

If everything is plugged in correctly and it still will not power on, follow these steps to complete a 'power reset' of the notebook.

1. Unplug the ac adapter. Keep ac adapter unplugged.
2. Remove the battery and keep the battery unplugged.
3. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
4. Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
5. Normally power on the notebook.
6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
   If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.

Try unplugging the power cable of the modem for about 15 minutes to let the memory clear the MAC address of the computer.
After 15 minutes, plug in the modem while connected to the router.
This should allow the modem to use the MAC address of the router and provide an IP address to it.

First, make sure it is fully charged and plugged in.
Look at the power indicator:
• If it is not lit, no power is being supplied to the computer. Check the
following:
• If you are using on the battery, it may be low and unable to power
the computer. Connect the AC adapter to recharge the battery pack.
• Make sure that the AC adapter is properly plugged into the computer
and to the power outlet.
• If it is lit, check the following:
• Is a non-bootable (non-system) disk in the external USB floppy drive?
Remove or replace it with a system disk and press <Ctrl> + <Alt> +
<Del> to restart the system.
Nothing appears on the screen.
The computer's power management system automatically blanks the screen to
save power. Press any key to turn the display back on.
If pressing a key does not turn the display back on, three things might be
the cause:
• The brightness level might be too low. Press <Fn> + <→> (increase) to
adjust the brightness level.
• The display device might be set to an external monitor. Press the display
toggle hotkey <Fn> + <F5> to toggle the display back to the computer.
• If the Sleep indicator is lit, the computer is in Sleep mode. Press and release
the power button to resume.

The CallPilot takes between 4 and 15 minutes (depending on software level) to boot up. After that, the lights should come on for each port connected to the telephone system. If not:
1. Check the wiring between the phone system and the CallPilot;
2. Make sure the wiring between the phone & voicemail systems is less than 50 ft. (15 meters);
3. Remove & reinsert he feature cartridge.
If still not working - the unit needs repair.

If after 30 seconds the control does not detect water entering machine, the valves will be turned off and the error code will be displayed.

Press PAUSE/CANCEL twice to clear the display.

Possible Causes / Procedure

• If there is no water in the unit:
- Make sure that both valves at the water source(s) are turned on all the way.
- Check for plugged or kinked inlet hoses or plugged screens in the inlet valves.
- Verify inlet valve operation.

• If there is water in the unit:
- Verify drain pump operation.
- Verify that the pressure switch hose is in good condition and properly connected to tub
and pressure switch.

1. Verify there is not a siphon problem.
2. Unplug washer or disconnect power.
3. Verify wire harness connections to inlet valves, pressure switch, drain pump, flow meter,
and Central Control Unit (CCU).
4. Check all hoses for possible leaks.
5. Plug in washer or reconnect power.
6. Verify pressure switch operation.
7. Verify flow meter operation by blowing air through the part and measuring the resistance.
8. Verify CCU operation by running a Diagnostic test or any cycle.
