Not powering on, but active power supply - Abit AB9 Pro Motherboard

There is a circuit breaker for power windows .
Power Window System Components
The power window system consists of the following components:
?€¢
Driver Door Switch (DDS)

?€¢
Passenger Door Switch (PDS)

?€¢
Body Control Module (BCM)

?€¢
Rear door power window switches

?€¢
Power window motors in each of the doors

?€¢
PWR WDO Circuit Breaker

Power Window System Controls
The power window system will operate anytime the Retained Accessory Power (RAP) system is active or when the ignition switch is in the ACCY or ON position.
The driver master control switches are integrated into the DDS. When a power window switch is activated in the up or down positions the DDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the DDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist and during window motor operation the DDS continues to monitor the motor current to verify proper window motor operation.
The DDS controls the passenger window by a serial message to the PDS. When a power window switch is activated in the up or down positions the PDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the PDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist, and during window motor operation the PDS continues to monitor the motor current to verify proper window motor operation. (Scan tool support is available for this system

RETAINED ACCSRY PRW BRKR 30 amp. located in the left instrument panel fuse box . if the breaker is good check power B+ at the drivers door switch . connector 1 terminal b yellow wire . Sometimes the wires inside the rubber boot coming from body to door break .

Older passive computer speakers do not need a power supply.
Modern active speakers might use batteries but mostly need a power supply that plugs into the mains power outlet and provides the right voltage, current and polarity the speakers need.

Some low-powered active speakers simply plug into the computer usb.

Yes. You can replace the both. http://electronicshelponline.blogspot.com/

ATX V2.3 / EPS12V V2.92 both define that the PSU has to use remote sensing to compensate cable drops on the 3.3V line. Because of this there is an additional brown cable crimped together with the orange cable either to pin 13 (ATX) or pin 1 (EPS12V). 14 -12V Blue -12 VDC 15 COM Black Ground 16 /PS_ON Green Power Supply On (active low). Short this pin to GND to switch power supply ON, disconnect from GND to switch OFF. 17 COM Black Ground 18 COM Black Ground 19 COM Black Ground 20 -5V White -5 VDC (this is optional on newer ATX-2 supplies, it is for use with older AT class expansion cards and can be omitted on newer units) 21 +5V Red +5 VDC 22 +5V Red +5 VDC 23 +5V Red +5 VDC 24 COM Black Ground /PSON activated by pressing and releasing the power button while the power supply is in standby mode. Activating /PSON connects the power supply's /PSON input to ground, thereby switching the power supply to full-on condition.

There is a critical system component hardware failure of some kind.

Please check the power supply unit. it is possible that the power output is less and so cut off when the power is activated.
Also it is possible there are errors in the main board and so when the CPU activates the power supply it encounters a SHORT and so cut off as a protection. if so remove main board and connectors to check by disconnection of circuits.

Hi,

Here are some of the steps to you can reboot your pc without using a keyboard:

1) Long press the power button
- Press the power button for about 3-5 seconds. If the power LED or power supply fan shuts off, that means you have successfully turn off your pc. Press it again to turn on.

2) Unplug the power cord from the power supply
- Force your pc to shutdown by unplugging the power cord from the power supply of your pc. Put it back again and press power button to turn on.

Note: Please make sure you have saved important activities before doing this as this will immediately turn off your pc.

Hope it helps.

Thanks!

/PSON activated by pressing and releasing the power button while the power supply is in standby mode. Activating /PSON connects the power supply's /PSON input to ground, thereby switching the power supply to full-on condition.
18 AWG is recommended for all wires except pin 11, which should be 22 AWG. For 300W configurations 16 AWG is recommended.
There are several ATX variants.
Hope this helps.
If this helps you resolve your problem, please
consider giving me a rating of 4.It will help me as well. Thank you.

1. remove the two rear screws and remove all the cards attached to the main board
2. unplug all the cables that connect from the drives to the board.
3. power on the unit
4. if the unit powers up, install one of the cards you removed and complete step 3
5. if the system does not power up, the last card or device activated will be your culprit and will need to be replaced or left out.

if you find that your system will not show a bios splash screen with all the other components removed, then you are looking at either a video, or power supply failure. Listen to your system for spinning fans and hdd activity. touch the hdd if you cant hear it when you power up the system, paying close attention to when the drive activates. It should activate almost immediatley, pause, and then run for a short boot period. if nothing, then if may be your power supply. you will not be able to see any lights at all, no light on the motherboard, drives, or power LED is the best indicator of a shot power supply

It sounds like you have a computer with an Active PFC (Power Factor Correction) Power Supply.

Back-UPS units, when running on battery power, output a Modulated / Stepped Sign Wave. Active PFC Power Supplies are NOT compatible with this pseudo-sign wave power, which is the reason it will not stay running.

You need a Smart-UPS unit, capable of delivering a true sign wave when on battery output.
