I need samsung nx5 service manual

When you connect the power adapter into the laptop, does the power LED light up? If not then - The battery adapter or the adapter's power lead or the laptop's power socket could be faulty. Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

Related to a Samsung Np-n145 Notebook PC:

Plug the laptop into power for 24 hours. See if the Battery charges up.

Next test, or have tested, the AC adapter (Charger) See if it is putting out 19 Volts -> DC.
Know someone with a multimeter? I can guide you in testing.

AC adapter is good? Things go downhill rapidly here.
The next problem could be a DC Power Jack.

The DC Power jack is the jack on the laptop, that you plug the AC adapter into,

1) The DC Power jack may be broken
2) The solder joints holding it to the motherboard may be cracked. Poor connection to motherboard.

The DC Power jack can be replaced, or it's solder joints re-soldered.

DC Power jack proves to be okay?

Power MOSFET's have gone bad. The next link, is an article that deals with bad Power MOSFET's in an HP laptop. Used for an example,

Let's hope it's a bad AC adapter

Knowing that the new AC adapter (power supply), is putting out 19 to 20.5 Volts (DC), then the problem needs to be diagnosed further.

[ AC adapter is checked with multimeter. Function knob set to DC Voltage. (Dotted line over a solid line) Center hole in plug for AC adapter, that goes to laptop, is the Positive connection. (Red probe lead of multimeter touches)

Outside metal shell of plug is Negative. (Black probe lead of multimeter touches) An economical multimeter can be purchased for around $5 to $12. A multitude of stores carry them. An auto parts store is but one example. Analog, or digital is fine]

The jack in the laptop, that the plug for the AC adapter (power supply), plugs into, is the DC Power Jack.

With many DC Power Jack's, the jack is soldered directly to the motherboard.

Not so with the Acer Aspire 5570z series of Notebook PC's.
The DC Power Jack is connected to a cable of wires, which in turn is connected to the motherboard.
DC Power Jack Harness.

Replacement, is disassembling the laptop down to the DC Power Jack harness, unplugging it's cable's connector, and plugging in a new DC Power Jack harness.

The Bottom Case holds the DC Power Jack in place. (There is a slot in the side of the case it sits in)

Battery removed use an object to see if you can wiggle the Center Pin around. (Pencil? Or C-a-r-e-f-u-l-l-y, a flat tip Jewelers screwdriver? )

Also see if the rest of the DC Power jack, that you can see, will move around.

A-N-Y perceptible movement means a problem with the DC Power Jack.
It would also be best to go further, disassemble down, and remove the DC Power Jack Harness, even if no movement is found.

Perform a Continuity Check with a multimeter. Check each wire in the harness to make sure they are good.


No problem found with the DC Power Jack?
Then the problem is a power sensor chipset, or chipsets, on the motherboard. This part of the laptop IS the power supply.
The AC adapter is just part of the power supply.

If this is found to be the problem, motherboard replacement is the viable solution.

[ Chip and Chipset are slang terms to denote I.C.
Integrated Circuit,

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

The power supply (Sensor chipset/s) senses whether the Battery needs a charge. Full or just trickle. It also senses when the laptop is to just run off of the AC adapter, and not the Battery, or Battery, and not the AC adapter.
{Plus a few other functions}

Here is the link to the Service Manual, (Free), for the Acer Aspire 5570 series of Notebook PC's,

Go to the second Aspire heading. The one that begins with Aspire 1200
Go down to the 8th line, and across to 5570. Left-click on 5570

1) Use an ESD wrist strap. Connect it's alligator clip to a good ground source. (Electro Static Discharge. I connect to an unpainted surface, of the metal frame of an open empty desktop computer case)

Average cost is around $3 to $6.
One example of an ESD wrist strap,

2) Use a multi-compartment container for the various screws you will remove.
Label each compartment for the area the screw/s come out of.
If no multi-compartment container is available, substitute with a clean egg carton.
Label each egg holder.
(Or double-sided tape, and label the tape)

There are screws which look VERY similar to others.
Do NOT mix them up.

3) Make a record as you disassemble. Make notes, drawings, and use a digital camera, or video cam, with good lighting.

Nice to have a record to refer back to, in case you are interrupted.
Also nice to have a Personal record made by you, along with the Service Manual

If this camera is like my FZ20, there is a socket to provide power to the camera from a mains adapter. The input socket is under the cover where the USB lead goes, and the manual shows a lead attached between this and a battery charger. My battery charger does not have this lead or DC output, though. The one that does is an optional extra, part DMW-CAC1. The manual recommends using the adapter to power the camera when it is connected to a computer, to make sure that a flat battery doesn't cause the memory to become corrupted.

My suggestion is that you attempt to power the camera through this DC power input, either with the approved adapter (maybe one of the chargers you are using has the output?) or with a generic one. I have successfully used a generic 9 volt adapter on my camera (positive center connector).

If it will power up with an adapter, I expect there is an issue with the connections in the battery housing. Otherwise, it might be a more fundamental fault.

1. Take the battery out of the laptop & try to turn on the laptop using power

adapter only. If the computer turns on, then the battery is defective & needs to be

replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the

power adapter using a voltmeter. Compare the voltmeter reading to the nominal value

written on the adapter or the laptop.
3. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re

-soldered. A broken one will need to be replaced.
4. If you have another processor which is compatible with your laptop's model, try

swapping processors & test to see if the laptop will work.
5. The power button could be bad.
6. The motherboard could be defective & needs to be replaced

Kodak has 3 types of charger that can be connected to a wall socket
USB AC Adapter - is especially useful when traveling, away from your computer, or just plain on-the-go. Connect your camera's USB cable to the adapter and plug it into a wall outlet to conveniently charge your camera.
5V AC Adapter - Provides in-camera charging for all KODAK EASYSHARE M and V Series Digital Cameras
Input: AC 100-240 V 50/60 Hz Output : DC 5.0 V
3V AC Adapter - Provides direct power to your camera but it will not charge the camera battery
Input: AC 100-240 V 50/60 Hz Output : DC 3.0 V

* You need to check the type of adapter your using. If your using the 5V AC adapter or USB adapter and the camera won't charge the battery contact kodak support line 1 800 235 6325 (23KODAK) for possible repair.

Try hard reset . Remove the batteries and insert new batteries . Sometimes this may work

Another chance is that lens is struck

* Carefully inspect around it for dirt or debris

* If you see any dirt or debris around the lens, use canned air to gently blow it away

* After removing dirt and debris, turn the camera on and off

This should work.

Try this alternate solution (got information from HP )

• Turn off the camera, if possible.
• If an SD memory card is installed, remove the card.

• Remove power from the camera as described below:

1. If you are using only batteries for power, open the battery/memory card door and remove both batteries.
2. If you are using only the AC power adapter, disconnect it from the camera.
3. If you are using both batteries and the AC power adapter, remove both batteries and the power adapter.

• Wait for 15 seconds. Then reinsert the batteries and close the battery/memory card door or reconnect the AC power adapter to the camera. If you are using both batteries and AC power, try each method separately.

• Turn the camera on and off. If the lens does not retract correctly or the camera does not turn on,

You need to take to service center .


Thanks for using FIxya

The T is the thermister that the battery charger uses to determine the battery temperature and make sure it's not being damaged by high temperatures, you can safely ignore it when you hook up an external supply, it won't cause any errors on the camera or anything.

If you want to hook up a DC adapter to your camera just make sure it's a well regulated (a switching power supply should be just fine, like a wall adapter only they're typically much lighter weight but adapt AC to DC) and is the correct voltage. The reason I recommend a switching power supply is that traditional wall transformers only provide the rated voltage at rated load, meaning if you hook up a 12VDC 2A wall adapter to something that draws 1/2A it will have a significantly higher voltage that it has stamped on its case.

Happy Hacking!
