Hi benno565, it's not shorting it's too loose from plugging & unplugging, hence your notebook is not getting a steady charge. You can bend the two prongs (every so slightly apart from each other), (carefully), this will give you a better connection or you can just replace the AC adapter. Your battery seems unable to hold a charge, that defenitly needs replaced.

I have an ASUS laptop which has been shutting down for the past 1 hour. It has little battery left so I have disconnected pwoer hoping it would go flat.

Asus WHAT laptop?
What is the model number? Bottom of laptop.

Two, is the laptop dirty inside?
If you have never had it cleaned, it is.

Three, "It has little battery left so I have disconnected power......."

Shouldn't have low battery power, if the thing is plugged in.

Four, have you tested the AC adapter's (Charger) output voltage?

Five, is the DC Power Jack in good condition?

[DC Power Jack (DC_IN), is the jack on the laptop that the AC adapter plugs into ]

Could be.........

A) The Battery is older than dirt........
("How old is that battery?
Lemme tell ya,.......that battery is so old that.........")

Battery needs replacing.

B) Power MOSFET's are going south for the winter, and didn't invite you, or the laptop along.

("Pssst..........let's go to the Bermuda's, but xnay on telling the laptop, or dlemaistre)

They control whether the Battery is to have a trickle charge, or full charge; OR, whether the laptop is to just run off of the AC power, and not the Battery.

(Actually the AC adapter {Charger} is a converter. Converts the AC electricity from the home, or business; into DC Voltage.
So it should be stated, ".......OR, whether the laptop is to just run off of DC power from the AC adapter)

Air is used to cool the hardware components inside the laptop.
The two hardware components that give off the most heat, is the Processor (CPU), and graphics chipset. (GPU)

When the Processor overheats it turns off. (BIOS turns it off)
This is a fail safe feature that is built-in.
Keeps the CPU (Processor) from burning up.

So the laptop could be turning off, because the Processor is turning off; due to the laptop is dirty inside.

The battery could be low on charge, because it is old; and not keeping a charge.

Power MOSFET's are bad, and battery is not being charged up.
Also no power TO motherboard of laptop, because power ends at the DC Power Jack on motherboard; and rest of motherboard isn't receiving power.

Using HP Pavilion dv6000 series, and Pavilion dv9000 series of Notebook PC's; to explain,

1) Is the laptop dirty inside?

2) Is the Battery more than 2 years old?

3) Does the AC adapter (Charger) prove to be good?
Putting out the required Voltage?

4) If the DC Power Jack on laptop, is the design that has a Center Pin; does the Center Pin move around, when you try to gently move it with a tool?
(BATTERY removed)

Gateway id49c notebook power issues

1) Test the AC adapter (Charger) first.

Test with a multimeter.
(An economical multimeter can be purchased for as little as $5 to $12. Available in a multitude of stores. An auto parts store is but one example. Checkout aisles of major discount stores, may have them on the rack)

Function knob set to DC Voltage.
(If just a symbol the symbol is a dotted line over a solid line)
If more than one DC Voltage scale set it to the 0 - 50 Volt scale.

Positive (Red) probe lead of multimeter goes to the Center Hole, of the plug end that plugs into the laptop.
Negative (Black) probe lead touches the cylindrical metal shell, on the outside of the plug end.

You should be reading 19 Volts DC.

Also have an assistant gently wiggle the cable from AC adapter to laptop, and power cable to AC adapter (Charger)
Fluctuation in the reading means you have broken wires.

AC adapter checks out OK?

2) DC Power Jack:

The DC Power Jack is the jack on the laptop, that you plug the AC adapter (Charger) into. (DC_IN)

Battery removed, (And AC adapter, 'natch), use a No.2 pencil, and with the eraser, gently see if you can move the Center Pin around.
ANY perceptible movement means damage to the DC Power Jack, and replacement.

3) AC adapter and DC Power Jack checks out?

Problems with the Power MOSFETs used in the power section, on the motherboard, or possibly Ceramic Capacitor failure.
(Multi-Layer Ceramic Capacitor, and they are Surface Mount Devices)

Using the HP Pavilion dv6000 series, and Pavilion dv9000 series of Notebook PC's, as an example,

Looking down at the second photo with the Alpha and Omega Semiconductor - AO4407 - Power MOSFET circled in Yellow, look at the small rectangular shaped object to it's Right. Has a wide dark band on it.

This is a Ceramic Capacitor.
There is one above it of the same size, one above that one, and one to the right of the top one.
If any one of these, or the Power MOSFETs are blistered, blackened, or bubbled, they need to be replaced.

Due to issues that could arise by replacing, and having more components be bad, or go bad; the logical choice by most tech's is to simply replace the motherboard.
(Also puts more dinero in their pockets)

Hello! Acer Aspire 7530 problem the motherboard no power on and no light any where.I dont where is the problem chipset or dioda? thank and the good day. Regards, Andrei

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.

Yes, you have had a severe hardware failure in your system. This unit requires repair and replacement of the defective components. It can be repaired however you would want to know going in exactly what the parts and labor costs, including any shipping would be. Depending on the age of the unit, the repair costs could equal a good portion of what a new system would cost.

I've witnessed multiple laptops do exactly what yours has done. Typically, the system board had to be replaced. Furthermore, I've seen these repair systems go up in smoke again shortly after receiving them back (from HP in my case).

Good luck and do your homework should you decide to repair.

Will Not charge with brand new a/ power cord it will at times power on if moved the right way but quickly powers off if moved the port inside looks to be fine But I hear there is a pin type thing inside...

The problem is with the AC adapter itself and is a very common problem with Dell AC adapters. My suggestion would be to get an aftermarket AC adapter that can be purchased on eBay as the Dell adapter is around 100.00. You can pick up an aftermarket one on eBay for around 20.00. The problem is a resistor inside the AC adapter that senses when a Dell branded adapter is inserted. What happens is that the resistor will get damaged and since it doesn't recognize the charger as a Dell branded one anymore it won't charge. However it will still run the laptop as long as it's connected. A lot of aftermarket AC adapters bypass this function and work perfectly fine.

I have a toshiba satellite A200 ,it works with batery but when i put the adapter of the ps ,the sceen becomes black and it will shut down ,so please help me

Sounds like you have a short somewhere: either inside your laptop or possibly the power adapter itself. The cheapest and easiest way to figure out which is causing the problem would be to take your laptop to a local computer shop and ask them if they have an adapter that's compatible with your laptop, then try the adapter with the battery in & out of your laptop. If it doesn't shut down, then I would say that your power adapter is shorting out and causing the problems. If it still has problems when using a different power adapter then I would say that there's something going on inside your laptop that is causing the problem. Many times it's because the female power jack on the motherboard needs to be replaced. There are several other things that would cause this to happen too, but what I've told you so far is the usual problem and solution - in my experience.

Medion laptop will not start - have checked power leads and battery - have tried starting without the battery in - could the motherboard be the problem and if so what do i need to do

After removing the battery, plug Ac adapter & hold power button for
20 secs. If it doesn't work, check if the Ac adapter with a multimeter. After that if problem continues, check the adapter (port) on the Motherboard if the solder is good. If it's not, you should solder it.
If all the above don't work, so it's probably time to replace motherboard.
Hope it helps. Please send me your feedback & vote to help us help you better.

Acer 5920-6474 does not power on

the problem lies with failed smd capacitors grounding out underneath the motherboard on the same side of the board as the cpu heatsink. if you look at the board with the heatsink/fan in the top right hand corner- the culprit caps are in the bottom right hand region under some see through plastic. they are labeled pc144 and pc145.

Satellite M40X won't boot

It is most likely a crack in the chip that sends power to the CPU. Fan is on different circuit and is getting power. Almost need a really strong maginifying glass to see a crack like that. Unfortunatly the best solution is a new motherboard. I have had some sucess with resoldering these chips but you need a hot air rework station to do a real repair. Hardest part is figuring out which chip it is. A lot of them are labeled MAXWIN ****. Should be fairly close to the CPU socket. Hope this helps, keep us posted. One other thing to try is pushing down on the laptop in the area of the cpu when you boot it and see if that helps. Opening and closing the laptop screen puts a lot of stress on the motherboard and over time will crack the cold solder joints.
