1) Check the AC adapter (Charger) to see if it is putting out 20 Volts DC.

Use a multimeter with the Function knob set to DC Voltage. If just a symbol, the symbol is a dotted line over a solid line.

If there is a multiple setting for the Function knob with DC Voltage, set it to the 0 to 50 Volt (DC) scale.

If you do not have one, or access to one, an economical yet reliable multimeter, can be purchased for as little as $10. (Less in some places)
A multitude of stores carry them. An auto parts store is but one example.
Analog or digital doesn't matter.

This is the DC Power Jack. May be labeled as DC IN on the laptop,

http://www.discountelectronics.com/index.php?l=product_detail&p=14640

I want to show you it, and have you look at the cable end, that is coming from the AC adapter (Charger) TO the laptop.
(To the DC Power Jack)

See the 3 pins? Arranged in a triangle? Note the socket holes in the cable end.
The pin that sits all by itself on Top, is the Positive pin.
The two pins down below are Negative, or Ground, pins.

The Positive (Red) probe lead of the multimeter, is inserted into the single socket hole, in the cable end.
The Negative (Black) probe lead can go into any of the two bottom socket holes.

Read very near 20 Volts?
Have an assistant wiggle both cables. First the one from the charger To the laptop, then the one from the charger to the wall receptacle. (Or surge protector, actually)

2) Charger checks out?
Go to the DC Power Jack.

You may wish to skip checking the charger out first, and check the DC Power Jack, if you Know that the charger is good.

Battery removed see if you can wiggle one of those 3 pins around.
Be gentle, use a pencil if available.
ANY perceptible movement means a Problem.

Looking back at the second link above showing the DC Power Jack, note the metal prongs coming down towards the bottom of the jack.
There are 4.
2 on each side.

Note the 3 long pins sticking down towards the back of the jack.

The 4 outside prongs made from the outer case, are used to anchor the jack into place. They go down through holes in the motherboard, and are soldered on the opposite side.

There may be Ground attached to the case through these prongs also.

The two pins sticking down towards the Back of the jack, are also Ground pins. (Negative)
The single pin by itself is Positive.

A) IF, any of the pins wiggle, the jack is broken, and needs to be replaced.

B) IF, the outer shell of the jack wiggles, the jack May just need to be soldered back into place.

(Could also be an indication of more damage than appears to the eye)

Same thing for the single Positive pin solder joint.

Charger checks out, DC Power Jack checks out, the problem may be a bad power sensor chipset.

This chipset senses when the laptop battery needs a full charge, or a trickle charge, or no charge.

This means it also will sense when the laptop is to be run straight off of the charger, and not the battery.

Usually means motherboard replacement, unless you have access to the chip, and means to replace it. (Soldering tools, and technique)

Appreciate it if you would keep me apprised as to what you find.

Well here is a way to check your power supply, on your hard drive connector using your volt meter and measuring from ground. this would be using one of two middle connectors it should measure +5 VDC on the red wire and + 12 VDC on the yellow wire. If these voltages are good then we got to see if the power supply is producing the -12VDC voltage. This voltage is ussed by the syustemboard on pin 14 of a 24 pin power supply. I would recommend not having your system board plugged in while measuring these votlages, but the power supply may need a load, I would plug in the cdrom.. Below are a couple of picture to explain this and a link to a website that has this documented.

http://www.playtool.com/pages/psuconnectors/connectors.html

The 24 pin main power connector was added in ATX12V 2.0 to provide extra power needed by PCI Express slots. The older 20 pin main power cable only has one 12 volt line. The new 24 pin connector added one line apiece for ground, 3.3, 5, and 12 volts. The extra pins made the auxiliary power cable unnecessary so most ATX12V 2.x power supplies don't have them. The 24 pin connector is polarized so it can only be plugged in pointing in the correct direction.

Good Luck I hope this helps.

This concern will require a volt/ohmn meter. If I am not mistaken, this scooter requires two 12 volt batteries wired in series. That is, the positive post of one battery connects to the negative post of the other and vice versa. This then constitutes an operational voltage of 24 volts. On most scooter chargers there are 3 pins that plug into the scooter to charge the batteries. On mine, the pin in the center pin is "ground". However, it is easily identified by setting the voltmeter to ohmns reading (a horseshoe shaped symbol) and doing what ever dissassembly is necessary to reach the scooter side wiring then touch one lead of the meter to either of the negative posts and the other to the exposed wires until the meter reads 0 ohmns or very close to this. This is the charger ground. Then set the meter to read DC voltage. Disconnect the charger from the scooter. Place the black lead on the meter on the identified ground of the charger and the red lead on either of the other two leads. There should be 12 volts either location. If there is not. the charger may be the problem. If there is, the batteries could have an internal problem and any auto parts store will happily check them for you.
Good luck and good hunting. If I can be of further help my email is [email protected]

Usually, two of the wires are "hot" and the third is a ground or neutral. Normally, on a three-pin Mike connector charger the two pins opposite each other are the hot pins, and the one at the base of the V is ground. If one of the wires not loose is at one of the pins at the top of the V on the charging port, putting a test lead between that and one of the other two should give you a reading of 24 bolts, assuming you are operating on a 24v system. The loose wire that give you the highest reading back to the non-loose wire should go opposite it at the top of the V and the other goes to the bottom. You charger will show the proper output by using the tester to test the output voltage so you can double-check this setup.

Yes this is a good list of the voltages to be expected from a newer power supply on just the main header

um what you want lol:?

Safing Sensor Diagnostic Circuit Open Or Low Resistance In A Primary Crash Sensor.

Each primary crash sensor has an internal resistor. The diagnostic monitor uses the resistor in the primary crash sensors in combination with the two resistors inside the diagnostic monitor to create a tightly controlled diagnostic voltage at Pin 11 (Circuit 614, GY/O). The primary crash sensors are tied together inside the diagnostic monitor at Pins 17 (Circuit 617, PK/O), 18 (Circuit 619, PK/W) and 19 (Circuit 621, W/Y). Therefore, the resistors in the sensors are connected in parallel. The parallel combination of all three sensor resistors should be equal to 393 ohms. The resistance of each sensor should be 1180 (± 20 ohms) ohms. The resistors inside the diagnostic monitor are connected to Pins 11 (Circuit 614, GY/O) and 12 (Circuit 623, P/W) and are equal in value. Note that Circuits 614 and 623 are tied together inside the safing sensor. Therefore, the two resistors inside the diagnostic monitor are connected in parallel and will function the same as one resistor of half the original value. Current flows from Pins 1 and 6 through the resistors, out to Circuits 614 (GY/O) and 623 (P/W) on Pins 11 and 12, through the LH B-pillar safing sensor and out to the driver side air bag. Current flows through the driver side air bag and into Pin 10 (Circuit 615, GY/W). Current then flows from Pin 10 through the diode inside the diagnostic monitor and out to the primary crash sensors through Pins 17, 18 and 19. The current flows through each primary crash sensor resistor and ends at the case ground of each sensor. Pin 11 is the midpoint of the resistor network and voltage at Pin 11 will change with vehicle charging system voltage. The expected voltage at Pin 11 is shown in the table below. The diagnostic monitor measures the vehicle charging system voltage at Pin 13 (battery input). By measuring the voltage at Pin 13, the diagnostic monitor can accurately predict what the voltage at Pin 11 should be in a normal functioning system. If the connection between Circuits 614 (GY/O) and 623 (P/W) inside the safing sensor is broken, then the resistor on Pin 12 is no longer in the diagnostic circuit. Both resistors are needed to pull up the diagnostic voltage to the correct value. In this situation, the resistor on Pin 11 is the only resistor inside the diagnostic monitor pulling up the voltage. Therefore, the voltage on Pin 11 will be half of the normal expected voltage and the voltage on Pin 12 will be about equal to the vehicle charging system voltage. The diagnostic monitor does not measure the voltage on Pin 12, so the monitor bases its decision strictly on the voltage at Pin 11. If the voltage at Pin 11 is lower than it should be, the monitor will flash Diagnostic Trouble Code 24. Another situation that can cause low voltage at Pin 11 is a drop in primary crash sensor resistance (resistance is too low). If this occurs, the voltage at Pin 11 will be pulled down to a lower than normal value because the parallel combination resistance of the primary crash sensors will be less than 393 ohms. In this situation, the voltage at Pins 11 and 12 will be identical, but the monitor does not measure the voltage at Pin 12. Therefore, a primary crash sensor with low resistance may cause low voltage at Pin 11 and the monitor will flash Diagnostic Trouble Code 24 on the air bag indicator.
Here is a wiring schematic of this.
