Doesn't work that way, verlinewms

Depending about what manufacturer, and model of laptop, we are 'talking' about here;

1) The DC Power Jack may be soldered directly to the motherboard,

OR,

2) It may have wires coming from it, that are inside a sleeve, and plug into a connector on the motherboard.
(DC Power Harness)

With the example stated in 1) above, you have to Completely disassemble the laptop, down to the bare motherboard in your hand.

(FOLLOWING Anti-Static precautions. Advise use an ESD wrist strap, and connect the alligator clip to a good ground source. Average cost is around $3 to $6. ALWAYS follow Anti-Static Precautions when working on a computer )

With example 2) above you disassemble the laptop, from the top down. Stop when the Palm Rest Cover is removed, in most cases.

[ Display Assembly removed. Then LED power strip above Keyboard. Then Keyboard. Then Palm Rest Cover. (Also referred to as Top Cover ]

Let me separately show you a basic example, for styles 1) and 2) above, using an HP laptop;

1) http://powerjack.us/index.php?main_page=product_info&products_id=8684&zenid=37ec82c9742dc233abe7f0e68d967ac7

With this style, the DC Power Jack has to be properly un-soldered from the motherboard, and a new one properly soldered in.

Click on the photo with the four views of this DC Power Jack.
Look at the view to the left/middle.

In relation to how this jack should be mounted on the motherboard, it is now laying on it's right side.

The pins, or prongs, on the left side in this view, go down through the motherboard.

A) The solder connections of those pins, (Prongs), can be cracked.
This makes an intermittent connection, which will soon go to no connection.

This style of DC Power Jack uses a Center Pin, and a surrounding metal shell. The shell is in segments.

The Center Pin is the most susceptible part, of this style of DC Power Jack,
to damage. It's just a large pin riveted to the back of the jack.
(Connected to a metal frame at the back)

This is just a short primer, of how to replace this style of DC Power Jack,

http://www.laptoprepair101.com/laptop/2007/12/06/dc-power-jack-repair-guide/

More info,

http://www.laptoprepair101.com/laptop/2008/10/28/fortify-damaged-power-jack-connection-in-laptop/


2) http://www.insidemylaptop.com/hp-g62-compaq-presario-cq62-disassembly/

Read, and observe the photos, but stop for a minute on Step 22.

The Yellow arrow is pointing to, the direction that the DC Power Harness plug, has to go in order to remove the plug from the connector, on the motherboard.

Looking at a photo of that DC Power Harness, will make more sense with the above photo, in Step 22,

http://www.laptoppowerdcjack.com/product_info.php?language=en&currency=USD&products_id=268

See the White long connector at the end of the DC Power Harness? (Towards bottom of photo)
Three Red wires, and two Black wires going to it?

In Step 22 this connector is next to the tip, or point, of the Yellow arrow.
The other end of the harness, or the DC Power Jack itself, is all the way to the Right.

It's sitting in a little U shaped channel, formed out of the plastic of the Bottom Case.

With this style you disassemble the laptop far enough down, (Top Cover, or also stated as Palm Rest Cover), to access the harness.
Then simply unplug it, plug a new one in, and reassemble the laptop.
(Remember - Anti-Static Precautions)

Look on the bottom of the laptop for the Model Number.
For HP it is the Product Number that is needed.
This is in a white Service Tag. P/N = Product Number

Post it back in a Comment.
(Caution! S/N = Serial Number. DO NOT post this on a public forum. Only give to an authorized HP dealer, or repair shop)

I may be able to give you a link to a free Service Manual, and would also like to post some pointers, if I may.

Regards,

You will probably have to strip it right down to get the motherboard out.
The socket might need resoldering. if you are not technically minded you would be better off taking it to a repair shop. You can do more damage than good if you are not careful. Youtube have a lot of videos about disassembling laptops / pc's if you want to do it yourself.

MBP screen hinge tightening


Hinges are located under the lcd screen and go into the bottom of the base or palmrest. You'll need to remove the strip that is right above the keyboard that normally houses the power button on most laptops. The strip might be secured by screws that are on the bottom of the laptop. Be careful removing the strip, most times there is a cable attached to it under the bottom. Once the strip is removed the hinges are exposed. Just take a phillips head screw driver and tighten them.

It might be possible that your power adapter died. But before reaching this conclusion remove your adapter from the outlet and the laptop. Examine for any broken connections and if none, try plugging it back in. Also try using your adapter on a different outlet.

2. Aslo check the battery life since could determine the possibilty of substituting power chord from currrent outlets with batteries

The device would not connect to power outlet without a properly functioning battery installed. A depleted battery could not be replaceble by connecting a source out power outlet. each parts of the power complement the entire process of achieving computer experiece.

Consult a technician insisting the replace the entire power system of battery and ac adapters and also fixing damages on the mother board may be contributing to power leakage

My laptop is not switcghing on


Is there enough charge on the battery? Does the problem occur when the AC/DC supply is plugged into the back of the laptop? The problem could lie with the battery, the power supply, or the motherboard. First, take the battery out of the laptop. It should be on the bottom of the laptop. Leave the battery out of the laptop. Next, plug the power supply into the laptop, and plug the power supply into a known working outlet. If the laptop comes on, then the problem lies with your battery. It will need replaced. If it doesn't come on, then it could be a bad power supply or motherboard. I would try a new power supply before replacing the motherboard.

Was using the laptop (dv6426us) and it just cut off. Was plugged into outlet with power supply, no warning messages prior to that. Now it will not power on at all, no lights, no beeps, nothing. If I unplug...


First, measure the voltage coming out of the power supply. If it is good (specs will be on the power brick itself.) then this sounds like a short on the motherboard. To eliminate all else, remove anything that is removable (hard drive, CD/DVD and RAM). Leave the battery out also. Plug in the power supply and see if it beeps. If not, you have a bad motherboard. If it does beep, replace the ram. At that point, you should be able to see POST. If you get nothing, it is the ram. Keep adding until the problem resurfaces. The last item added is the culprit.
Good luck.

Charger for E1705 beeps and no green light


You are describing a classic wiring short circuit. Either the cables of your power supply or the jack on the laptop itself are damaged and need to be repaired or replaced as soon as possible to avoid permanent damage. There is no logical reason it would work only in certain outlets, that is probably just coincidental to the way you have the cable running while plugged in to each outlet.

Your power supply has two cables, the side leading to the AC outlet is removeable and easily replaced but the side leading to the laptop's jack is not. Start with the AC plug. Leaving everything from the 'brick' to the laptop in a stable position, gently flex the AC cable until you see evidence of the short (usually a break in the wire, possibly chewed by the dog or snagged on the edge of a desk). If so, replace the AC wire. If not, try the same with the laptop side of the brick. If so you usually should replace the entire power supply unless you are real handy with a soldering iron.

If moving the position of the two power supply cables doesn't identify the short, you must suspect the laptop's jack of being loose. This is worst of all because the laptop motherboard has to be removed to gain access to resolder the jack, a professional job that will run probably $100.

Power BOX supply cord problem or hardrive problem?


Check these settings first. In a clear spot on the screen where no icons are, right click and go to properties, box opens and at top should list from R to L, themes-desktop-screensaver-appearance-advanced. click on screensaver, close to bottom click on power, another box should open, click on power schemes, make sure it's set to portable/laptop, and at bottom make sure settings for plugged in are are set to never. If it's not that then you have a bad power supply cord, or a bad power supply unit in laptop. If it's new and under warranty take it in and have replaced if not warrantied then will cost you about 100-150, just a guess!! hope this helps. But it sounds like the supply cord making the beeping noise might be bad. Make sure it's plugged all the way in as well.

Drainage


Turn off the hot and cold water supplies and remove the power supply cord from the outlet. Remove the lower front panel by removing three torx screws, one located at the lower left corner, lower center, and lower right corner. The panel removes easily. Located at the bottom center of the cavity is a large ivory colored filter with a turn cap. Get a shallow container or alot of towels, and slowly turn the slotted cover to the left a little at a time until no water runs.  Remove the filter and any debris that may be inside. Wash and dry the filter and replace, tightening the cover securely. Replace the lower panel, turn on the water supplies and plug in the power supply.  This should solve your problem and also relieve any standing water in the drum following a wash.  You may want to do this every 3 months or so as this is an easy fix
