How to replace the ac jack on a n610c

I need to replace the AC Jack on my HP n610c laptop computer

    I presume your AC cable got damaged.

    The solution is "simple and easy", but since you don't know how to do
    it yourself, I'll presume you have no experience with electronics. Solution involves "meddling" with high voltage, therefore I'll have to insist you upload a picture of the defect, but in any case it's a must-see in order to provide the correct repair /salvage instructions.

    Please, snap a close-up picture of the damaged part and a picture of a whole laptop power supply. You can upload them on http://www.imageshack.us/ and then post the links here. I'll provide you with instructions afterwards.

Dear Porque,

Try this: Get a standard wall plug from the store with three prongs. Cut off your AC jack at the end near the base of the jack. You will see two wire sets, one copper (brown) the other most probably silver in color. In your new plug, fasten the copper wire with the screw labled L, and the other wire in the screw labled N (neutral) or E (earth).

Replace the plug cover. Plug in your laptop and watch for battery charge indicator. If it discarges the battery in five minutes, your wires are crossed inthe plug. Check again.

If you go to the store with that plug, someone can install it for you at probably no charge at all. I hope there are such nice people in your country

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.

OR,
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,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

So,.......
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)

Screen doesn't come on power indicator light on when plugged in, any suggestions?


1) Unplug AC adapter (Charger) from surge protector strip. Unplug AC adapter from laptop. Plug AC adapter back into power, then plug back into laptop.

No?

Then the AC adapter needs to be checked.

http://www.ebay.com/itm/AC-ADAPTER-CHARGER-Everex-Stepnote-NM3500W-NM3900W-bfj-/390447149498?pt=Laptop_Adapters_Chargers&hash=item5ae876b1ba

The AC adapter converts high 100 to 240 Volts AC, from your home or business; into 19 Volts DC. (19VDC)

Looking at the AC adapter example above, the plug end that plugs into the laptop; has two connections;

1) The Center Hole is the Positive connection.
2) The outside cylindrical metal shell is the Negative connection.

Using a multimeter to check;
Set the Function knob to DC Voltage. If just a symbol, the symbol is a dotted line over a solid line.
If there is more than one DC Voltage scale, set the Function knob to the 0-50 Volt DC scale. (0 to 50 Volt)

The Positive (Red) probe lead goes to the Center Hole.
The Negative (Black) probe lead goes to the cylindrical metal shell.
You should be reading 19 Volts (DC)

Have an assistant gently wiggle the cable FROM AC adapter TO laptop.
Also have the assistant gently wiggle the power cable FROM surge protector TO AC adapter.
Fluctuation in reading on multimeter; indicates a broken wire, in one of those cables.

Replace AC adapter if so.
Not 19 Volt reading? Replace AC adapter.

[An economical multimeter can be purchased, for as little as $5 to $12. An auto parts store is but one place to puchase one. I have seen them on checkout aisle racks, in major discount stores.

I can guide you step by step with it, if you post the manufacturer name, and model number of the multimeter.
Skittish about measuring the voltage? Worried about shock?
I understand. However, I wish you to know that two D cell flashlight batteries, store 3 Volts DC. You will be measuring for 19 Volts DC.

Or take the AC adapter to the nearest small computer shop. The resident tech should only charge a couple of bucks, to test it for you]

AC adapter checks out?
Then the diagnosis goes on.
(Or you may wish to skip to the next step, and perform it first)

DC Power Jack:
The DC Power Jack is the jack on the laptop, that the AC adapter plugs into.

http://www.ebay.com/itm/Everex-StepNote-NM3500W-Motherboard-WORKING-/230663580965?pt=LH_DefaultDomain_0&hash=item35b49eed25

Looking at the photo of the motherboard, you are looking at a Bottom view. The Processor, and Ram Memory are on the Bottom of the motherboard.

There are two silvery looking ports, on the BOTTOM/Left corner.
The one all the way to the Left, is the Ethernet port.
Next to it on the right; is the DC Power Jack.

Another look at the jack not installed;

http://powerjack.us/index.php?main_page=product_info&cPath=105&products_id=13456

Great! Can't find an exact listing for an Everex NM3500w DC Power Jack.
However the above example mounts the same. The connecting prongs (pins) on bottom, may be in a different pattern, though.

Click on the photo to enlarge.
This shows a bottom view of the jack. The rounded tipped prongs go through holes in the motherboard, and are soldered on the opposite side.

The prong all the way in the back of the jack, left side; goes to the Center Pin. The Center Pin is the Positive connection.
The prong coming up from it in the middle, is for the Negative connection. It goes to the contact/s surrounding the inner hole, in the jack. (Inner hole around the Center Pin)

Battery removed, AC adapter removed; see if you can gently move the Center Pin, using an eraser on the end of a No.2 pencil.

ANY perceptible movement means the DC Power Jack needs to be replaced.
If it seems the entire jack itself moves, problem may just be a cracked solder joint, or joints. Or may be a bad power jack.

A cracked solder joint will make an intermittent contact, or No contact at all; of DC Power Jack TO motherboard.
Battery will not receive power, laptop will not turn on.

Power On LED indicator is on? Means nothing really. Uses way less than 1 Watt of power to light that LED. (Light Emitting Diode)
A cracked solder joint could allow that much power, but not enough to turn the Processor on.

DC Power Jack seems fine, from this simple cursory test?
You really have to disassemble the laptop, remove the motherboard, and check; to be sure.

See if by gently wiggling the Body of the DC Power Jack, if there is any perceptible movement.
Use a bright light, and magnifying glass; to carefully scrutinize for a cracked solder joint.

AC adapter checks out? DC Power Jack checks out? Next in line are the Power MOSFET's.
Now we are talking board level component replacement; (SMD's), Or motherboard replacement.

!O_O!
Using the HP Pavilion dv6000 series, and Pavilion dv9000 series of Notebook PC's; for info about Power MOSFET's in the charging/power section, of the laptop's motherboard. (DC to DC Circuit),

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

Cost exceeds repairing laptop feasibly, and you need to retain the information on the Harddrive?
Suggest removing harddrive, and installing in an economical external enclosure.

The harddrive resides in a Harddrive Caddy. A sheet metal enclosure. Then both are installed in the laptop. The sheet metal Harddrive Caddy is removed, so the Harddrive can be installed in the external enclosure.

Don't know what technology the Harddrive uses.
Do not know if it is an IDE (PATA) unit, or a SATA unit.
DO KNOW that it is a laptop harddrive, and will be 2.5 inches across in Width.

(2 and 1/2 Inches)

Once the Harddrive is removed, you can look the model number up on the internet, and see if it is an IDE, or SATA unit.

[IDE is referred to as PATA also. Parallel ATA.
SATA is Serial ATA,

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

http://en.wikipedia.org/wiki/Serial_ATA ]

You can also post back here with the Harddrive's model number, and I can find the information out for you.

IDE (PATA) example;

(Scroll down)

SATA example,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5601768&CatId=2783

Scroll down)

Reviews I found on the 'net were few, and lacking. One's for sale on places like Ebay, give sketchy information on what the laptop even looks like.
However I believe I can guide in disassembling, if you wish.

Gateway id49c notebook power issues


http://support.gateway.com/s/notebook/2010/gateway/id/id49C/ID49Cnv.shtml

1) Test the AC adapter (Charger) first.

http://www.itsbattery.com/gateway-ac-adapter/Gateway-ID49C-AC-Adapter.html

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,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

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)

Samsung n145 will not power up


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,

Is not charging battery


If the laptop works with the AC Adapter Power Cord ok without any problems except the battery is not charging, then the battery is dead. Batteries only have a useful life, then they have to be replaced.

If the laptop does not work with the AC Adapter Power Cord then either the Power Cord is bad or the DC Power Jack where the power cord plugs into the laptop is bad. If either of these is bad, a good battery will not charge.

Check your DC Power Jack which is where the power cord plugs into the computer is bad. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

I bought new universal adapter for asus laptop and it charges batery just when laptop is turned off


Problem description: The battery charges only when the laptop turned off. The battery charge LED lights up as normal and the battery gets charged to 100% while the laptop is off.
When the laptop is turned on, the battery charge LED goes off even if the adapter is still plugged in.
Possible cause: 1. AC power adapter failure.
2. Battery failure.
3. Broken/loose power jack.
4. Motherboard failure.
Possible troubleshooting steps and repair solution: 1. This problem could be related to a faulty AC power adapter. It's possible that the AC adapter doesn't provide enough power when plugged into the laptop. To find out if this is your problem, you'll have to test the laptop with another working adapter.Replace the adapter if needed.
2. There is a slight chance that you have bad battery. Test the laptop with a know good battery and replace the faulty one if needed.
3. The battery charge problem could be related to the power jack. Maybe the jack is broken or not making good contact with the motherboard. It is necessary to remove the motherboard and take a closer look at the power jack. Resolder or replace the jack if needed.
4. If the power jack is in a good working shape and new power adapter with battery do not fix the problem, most likely you have a faulty motherboard. Replace the motherboard if needed.

HP Compaq laptop won't charge/power from AC due to blown fuse


Hi there,

There's plenty of causes why your laptop would not power up from the AC adapter and won't charge the battery. Here are some possible causes and solutions to this problem:

Number one, if it's on battery power, the battery is dead or the battery is bad and number two the AC adapter could be bad. Let's roll out number one.

1. Take out the battery, remove main supply, hold power button down for 30 seconds. This will drain the charges in your

battery. Put only power supply in, do not put battery in, turn laptop on, put the battery in.

2. If the solution in no.1 doesn't solve the problem, pull the battery out, keep the battery out of the laptop for this test.

Take your AC adapter and check the voltage with a voltmeter. What you want to test for is voltage. Put the meter at 20

volts DC and take the tip, the power jack tip of your AC power adapter. You hold the black, (the negative part) of your

voltmeter on the outside of the power jack tip of your AC adapter and you put the red (the positive part) of your voltmeter

in the hole in the inside of the power jack tip of your AC adapter. Be very careful not to touch the red and the black part of

your multimeter and the power jack tips of your AC adapter together, otherwise it will create a short circuit.

After doing these procedures, if your AC adapter is good it will output a voltage which ranges from 18 to 19V DC on your

voltmeter, depending on the voltage that puts out on your AC power adapter. If your voltmeter doesn't show any voltage,

probably your AC power adapter is bad or damaged. But if your voltmeter shows up voltage, then we have to go to the

next possible cause why your laptop won't power on.

3. The dc jack on your laptop might be bad, if the dc jack on your laptop is bad or not making a connection to the

motherboard then it look the battery is bad as well, because the battery is now not holding a charge or even taking a

charge. Also, even if your AC power adapter is good and when you insert it to the dc jack in your laptop it could not power

up the laptop because the dc jack is not making a connection to your laptop motherboard in other words the dc jack might

got loose, that's why it's not making any connection to the motherboard. The only way to solve this is that you have to

disassemble your laptop, and take the laptop motherboard out and look where the dc jack is connected. After you found it,
take a file tool and file off a spot on the motherboard where you can reattach the power jack and use a wire to reattach

the power jack to the motherboard.

Hope you find this answer helpful. God bless.

Toshiba plug-in ac adapter LCDlight flashing and wont boot up


It may be that you need a new, (Or good condition used), motherboard. You may not.

The problem could be the DC Power Jack. The DC Power Jack is small, and the body is made of plastic. Sometimes there is a metal shell around the plastic body. (The jack is a rectangular shape, and is just a little larger, than the outside portion of that AC adapter plug!)

This is an example of a DC Power jack for a Toshiba Satellite a215-s5807,
http://www.notebookworks.net/ProductDetails.asp?ProductCode=NBW52-0133

As you know there is a metal pin in the center, and at the back of the round hole, there are flat metal contacts.

Let me explain the construction of a DC Power Jack, and how it's mounted to a motherboard. This all has relevance to the solution.

Your laptop uses DC electricity. (The AC adapter converts AC to DC. Your laptop battery, and a flashlight battery, are examples of stored DC electricity)

DC uses a Positive connection, and a Negative connection. The metal pin in the center is Positive. The flat metal strips at the back are Negative.

That laptop DC Power Jack has metal prongs, that come out of the plastic body. One prong, (Or pin), connects to the Positive metal round pin, in the center of the jack.
There may be one, or two prongs, (Or pins), that come out of the plastic body, and connect to the Negative side of the jack. (Flat metal strips)
These prongs go down through holes in the motherboard, and are soldered on.

With the AC adapter plugged in, an accidental bump on the plug itself, could break the body of the jack, or break solder joints that hold the jack to the motherboard.

AC adapter removed, and battery removed. Use a NON-metallic object, and see if you can make the center pin of the jack move. See if the entire jack itself seems to move.
A.If the center pin moves, you have a broken DC Power Jack.
B.If the entire jack moves, you have cracked solder joints. (Broken)

Replacement of the DC Power Jack for A.
Re-solder the solder joint/s for B.

Cost of replacing a jack at a reputable computer repair shop? $90 to $150
Cost of re-soldering solder joints? $50 to $90
Cost of replacing the motherboard?
$250 on up.

If you are a skilled person with the correct tools, it is feasible for you to replace the jack, or re-solder the solder joints.
It is also feasible that you yourself, could replace the motherboard.

Some laptops have a poor motherboard design, for where the DC Power Jack is mounted to the motherboard.

Crude explanation would be, that the main body of the motherboard is a 1 foot square. Then a 2 inch square comes out of the side of the main body.
The DC Power Jack is mounted to that 2 inch square. From accidental bumping, OR just normal usage of inserting, and removing the AC adapter plug, this 2 inch square can crack away from the main body.
This, of course would require a motherboard replacement.

Disassembly instructions for a Satellite A200 and A205 Series laptops. Very close to the A215 Series,
http://www.irisvista.com/tech/laptops/toshiba-satellite-a205/laptop-disassembly-1.htm

(Don't forget to buy, and use a cheap ESD wrist strap, to prevent static shock to the delicate hardware components, inside your laptop. Average cost is $7)

Motherboard issue


It's a power issue. The battery is flat. (No charge present) The AC adapter (Charger) is plugged in. The DC Power Jack has an intermittent contact. (The DC Power Jack is where the AC adapter plugs in. The charger)

The DC Power Jack is broken itself, or where it's soldered onto the motherboard, the solder joint/s are broken. This gives an intermittent contact. To see if this is the issue, try holding the plug for the charger over to one side, when it's plugged into the laptop. You may have to move it side to side, or up an down, to see.

If this is the issue, the DC Power jack costs about $6 bucks. The cost to replace it is $120 to $150.

The tech has to completely disassemble the laptop, until just the motherboard is in hand. The old DC Power Jack is unsoldered, and a new one is soldered in. Then the laptop is reassembled.

IF, you can find a shop! Most of the time the entire motherboard is changed out. Now you're talking Ducketts! $$$$$$$
