Hey, its kinda tricky if you aint done it before, go onto google and search for your laptop model dc jack, they usually cost about £5 including postage, then you need to dismantle the entire laptop, remembering where each part goes back into, once you get the motherboard removed you need to unsoldier the old dc jack, and put in new one and resoldier it.
will take you about 1-2hrs in total, or should cost you about £55 for a shop to do it.

we do alot of them, but if you aint done this before it can be very tricky..

Hope this helps

How do i repair an ASUS z53E motherboard?


Have you confirmed that it is indeed the laptop? (IE attached another power supply of same voltage/amperage) Sometime, cords can become frayed inside the laptop power supply cable and not show any outward signs. This wear and tear leads to unstable power and the laptop senses this and will not boot.

If you have, have the laptop checked at a local repair shop to see if it is a loose connection on the motherboard. Ports coming loose from the motherboard because of wear and tear is very common.

Tip

Laptop is plugged in but says it is running on battery.


You have your laptop plugged in but when you check it says that you are running on battery. Or, you have your laptop plugged in and it will not work because the battery is dead.

Both scenarios depict a broken power port on the laptop or possibly a bad power supply. Checking the power supply is easy. Using a DMM on volts DC set to 20 place the red lead on the center pin and the black lead on the outside of the plug assembly. If you do not have the correct voltage as listed on the power supply then you need a new one. While holding the leads on the power plug wiggle the wiring to make sure there are no breaks. If the power drops to zero at any time you need a new power supply. A good site is http://www.impactcomputers.com .

Many times people do not realize that their power port is broken until it is too late. If you continue to use your laptop after the port is broken you will destroy the power supply portion of the mainboard and it will cost you half as much as the laptop cost to repair and may make it not worth fixing.

When you realize that your laptop is not running on AC power, and it could be intermittant, you need to immediately take it to a repair facility to get the jack replaced. The average cost should not exceed $150 US.

This is not a repair procedure that I can walk you through. You can only get your unit repaired at an experienced reapair facility.

My charger will shut off when I plug in into my laptop. I have bought a new one and still same problem.


The charger is supplying power to the laptop, but the power is not making a circuit, other indications are that the led on the charger might flash before powering off.

You have a problem with EITHER the charger port (check where the charger plugs into feels loose) OR the charging circuit on the motherboard is damaged OR (if fitted) the cable that connects the charger port to the motherboard is broken.

If you can still power from a battery, at least the laptop might be able to be repaired , but you need to dismantle the laptop, check the charger port and where it connects to the motherboard, if there is charring here, or burning around the contacts, the motherboard will need replacing, if it has just come loose, you can obtain the part off ebay or similar and resolder it onto the board. If it is the connection cable variety, this is even easier as a replacement will simply plug into the board (check existing cable for continuity using a multimeter first).

If there is charring or the repair will not work, I suggest you have someone remove the motherboard. Check the inline ceramic fuse near the charge port and make sure this is intact (if not it will need replacing), and also on the underside of the board, check that there are no burned or melted resistors. If this IS the case, the motherboard is scrap.

Depending on the age of the laptop in this case, you might find it better to sell it for parts and get a new one

How to repair the dso power supply ? is there a circuit diagram ? thx


repairing a power supply do not need a diagram often faulty on a power supply are the regulator transistor,capacitors,resistors,and diodes. just check these parts and you can fix the power supply.check also for loose contacts and connectors this also cause a fault on the power supply.

Dropped Averatec 3200 laptop and it fell on the cord and bent the power source connection. Can I fix this or do I need to send for repair?


I've had this happen to me a few times. If the pin inside the laptop is bent, then there is no question that you'll need a warranty or shop repair on the laptop to fix or replace the power port.

If the power input coming from the power supply is bent, then you can try fixing it by pushing the plug back into place with a pair of pliers. If this doesn't work, then you'll need a replacement power supply or repair.

Acer Aspire 5520 Power Problems! :(


1. Actually the problem is not with the charger / adapter!

2. The plug-in port / jack of the laptop has become loose.

3. Don't try to work out the charging by adjusting the adapter plug with different angles. It will just damage the plug-in port (the wire inside the port will become loose and unaligned)!

4. Contact the Acer authorised service center for repair / replacement of that plug-in port / jack in the laptop! It'll just cost some bucks!

please rate this advice if it helps....tc! :)

Power problem


Check the port on the laptop where you plug in the adapter. Try to wiggle and see if you have a loose AC/DC input jack.
If yes, you need to have it repaired, unfortunately. If not, remove the battery then plug the adapter and see if you can see a light or if you can boot up the laptop.
You may try plugging it in on a different wall outlet.
Hope this helps.

Service Plan repair (#C3978905) on laptop


This problem could occur if one or more USB devices are drawing more power than the USB port can deliver.
You can purchase a powered USB 4 port hub and connect it to the laptop, this would supply independent power and not draw power from the laptop.
