I plug dc in an power light comes

It should be 32 volts DC ..this purple one only has two pins in it...now the gray one's have 3 pins..and I think it has 32 volts DC and 16 volts DC out...

Probably a broken cord/cable. You'll need an multimeter/voltimeter to check it out.

Whenyou connect the power adapter into the laptop, does the power LED lightup? If not then -The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty.Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced.If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard.This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

Around this shop we diagnose, and not assume.

1) Test the AC adapter (Charger)
Test with a multimeter set to DC Voltage. You should read VERY close to 19 Volts. (DC)

While testing have an assistant gently wiggle the power cord TO the AC adapter, and the power cable coming FROM the AC adapter.
See if there is an intermittent reading for either one. Indicates a break in the wire/s.

2) AC adapter checks out OK go to the DC Power Jack. This jack is the port on the side of the laptop, that the AC adapter plugs into.
(DC IN)

Remove the Battery, see if you can gently wiggle the Center Pin. Use a non-metallic object, or tool.

Also check if the metal shell inside the DC Power Jack moves around.
ANY perceptible movement indicates a problem with the DC Power Jack.

Fortunately, for this model the DC Power Jack is a Power Jack Harness,

http://www.lapdiy.com/toshiba-satellite-l305s5941-power-jack-wire-port-dc-in-cable-p-7556.html

The jack portion is a squarish shape with a channel formed around it, and sits in a cutout formed in the outside edge, of the Lower Case.

The harness coming from the jack has a plug on the end.
You just unplug it, and plug a new one back in.

In the photo above, it shows a Toshiba Satellite L305 series Notebook PC, partially disassembled.

On the right side you see the optical drive. Squarish shaped with one corner gone. Has a large white label on it, with a smaller yellow rectangular label.

To the upper right you can barely make out a Red wire. It is connected to the black DC Power Jack.

Looking straight across from it to the Left, you see the other end of the Red wire connected to a white plug.

That's the DC Power Harness, and where it plugs in.

Posted to show the DC Power Harness, and a pictorial guide that I feel will help get you started.

3) Power Button Board:
Has the Power On switch on it,

http://www.laptoppartsexpert.com/i-7600699-power-button-board.html

If the Power On switch is working, the laptop isn't going to turn on.
('Natch)

See the two wires coming from the board? Black and Red?
Red is the Positive wire, Black is the Negative wire.

Unplug the Power Button Board's plug to the motherboard. There are 2 pins. Carefully touch a small flat tipped screwdriver, (Jewelers is recommended), BRIEFLY to these 2 pins.

Laptop comes on you have a bad Power Button Board.

4) If none of the above is the problem you have a bad power sensor chip.
It's a Power MOSFET.

http://en.wikipedia.org/wiki/Power_MOSFET

Soldered to the motherboard, and takes skill to replace.

(It's a power transistor that is used in the circuit.
Need to use Heatsinks on the J type leads when replacing, and good skills for un-soldering/soldering.

But doesn't take a rocket scientist to replace it.
{ Sorry Gort }

This example is used in a LOT of laptops,

Or replace the motherboard.

It sounds like either a bad connection on the motherboard or a broken wire in the adapter making intermittent connection.

1. With the power adapter disconnected, do you have a power light? This would indicate the adapter is good and the plug is questionable.

2. Check your power adapter output with a multi-meter.(be sure to wiggle the wires around) If the power fluctuates, replace the plug.

3. If the power is solid, replace the motherboard connector.

The DC Power Jack that the AC adapter (Charger) plugs into?

Look into the DC Power Jack with a magnifying glass and light you'll see it's a center pin surrounded by a barrel. Barrel has an inside and an outside.


1) Center pin. Gold and buried down in the plastic. Connected to WHITE wire at motherboard connector.

2) Inside barrel has 4 Brass fingers.
Orient the laptop so the LED is at 12 o'clock and you'll see fingers at 12, 3, 6 and 9 o'clock.

These fingers carry the + 19 volt power to computer.
The ones at 6 and 9 o'clock do, Noon and 3 are not connected.
+19 Volt power arrives at motherboard connector on RED wire.

3. Outside barrel has six brass fingers, at 2, 3, 4, 8, 9 and 10 o'clock.
2, 3, and 4 are not used,
2, 8, 9 and 10 are the power return (common, or ground) to computer.
It arrives at motherboard on BLACK wire.

4. LED is connected to YELLOW wire and controlled by computer.
Other side of LED is jumpered to a Black wire,(Ground), outside barrel 8, 9, and 10 o'clock.

switch power back off, teun it on, hold power touch on the front down--> PS3 will turn on, keep holding until it turns off. when it turns off, take of your finger. hold down your finger again on the power touch, green light will blink, keep holding, you will hear one peep, then two peeps (when you hear the two peeps take off you finger); a menu will show up, chose restore factory default setting then ok, PS3 will restart, hopefully that will fix it

1) Disconnect the plug.
2) Remove the 3 hex screws holding the cover.
3) Make a note of all connections (taking a picture is even better).
4) Connect the black power wire to the red transformer wire.
5) Connect the white power wire to the white transformer wire.
6) Set your voltmeter to 20 or 50 volts AC (not DC and not less than 15 volts).
7) Plug the transformer in the wall.
8) Test the voltage coming from the A & B connectors at the back (polarity is irrelevant).
If you see 12 volts or thereabout, the problem is with the little switch (the one with the black and red wires that is activated by the trippers on the clock dial). I have the exact same problem but I have been unable to locate the part so I am going to try to clean the contact points and see if that works.

open it up... whats the worst that could happen... see if the caps are fine... if they are bloated exchange them... if you need help doing so hit me up at abelino24(at)sbcglobal(.)net... I've repaired like three of these in the past few months.. its always the capacitors. they either get really hot and bloat or don't function if it gets too cold... so the solution if to get the right caps at 470uf / 25v and 220uf / 25v... hopes this helps...
