Motherboard or harddrive? I'm betting it's more towards the motherboard. The DC Power Jack to be more specific. This is the port where the AC adapter, (Charger), plug is plugged into.

The DC Power Jack is not much bigger, than the plug for the AC adapter that plugs into it. There are small pin leads that are on the bottom of this jack, and they go through the motherboard, and are soldered to the motherboard.

Accidental bumping of the AC adapter plug, while plugged into the DC Power Jack, can damage the jack. It can break the connections for the adapter plug, and/or can crack the solder joints for those small pin leads.

[Laptops use DC electricity. A flashlight battery, and a laptop battery, are examples of stored DC electricity. DC electricity has two poles. Positive and Negative. The DC Power Jack has two connections. Positive and Negative. {Even if the DC Power Jack has multiple holes in it]

There is also another known problem associated with DC Power Jacks. It may stem from a bad motherboard design.

More to the point, the area where the DC Power Jack mounts on the motherboard. In this design, the DC Power Jack motherboard area, is almost a separate part of the motherboard. It's shaped like a Peninsula. (Think of an island, with one side connected to the mainland)

This peninsula shape, has the tendency to crack away from the main body of the motherboard. Circuit traces are broken.

When the AC adapter plug is setting in a certain position, it presses the two broken halves of the circuit traces together, for a momentary contact. As the AC adapter plug is moved from this position, the circuit trace halves are moved apart, and there is no contact.

(No distribution of electricity from one circuit trace half, to the other circuit trace half. Think of a circuit trace as a very, thin, flat copper wire. When a circuit trace is broken, there is essentially a wire that is broken into two parts)

Solution?
See if the DC Power Jack can be repaired, (Solder joint connections re-soldered), or replaced.
If the DC Power Jack motherboard area is the aforementioned peninsula shape, it may require replacement of the motherboard.

There are very FEW, computer repair shops that have the technical expertise to replace a DC Power Jack. Easy fix is to simply replace the motherboard. (More $$$$$ too)

However, some laptops DO require replacement of the motherboard for this repair.
Bad motherboard design, for the DC Power Jack area on the motherboard.

Re-solder DC Power Jack solder joints? (IF, this is the problem) Average is $50 to $75 (US)
Replace DC Power Jack? Average is $125 to $150. (US)
Replace motherboard? Depends on the Gateway model. Could be $225 to $400 (US)

[Yes, most of the time the cost warrants just replacing the laptop itself, as the cost of replacing, is close to the repair cost)

Just to SHOW you ab average DC Power Jack, and the repair involved of replacing. (Doesn't show you, that the entire laptop needs to be disassembled, down to the bare motherboard in hand)

This is NOT a recommendation to replace the DC Power Jack yourself! It is just for knowledge of what is partially involved. (You can accidentally burn the motherboard when desoldering, or soldering, rendering the motherboard useless)

Joecoolvette makes a good point that no matter what kind of computer problem you have, if you don't know how to fix it yourself it's usually better just contact a <a rel='nofollow' href="http://ifixny.com">computer repair</a> expert. There is no use holding out luck that you can do it yourself if it's truly beyond your expertise.

My nv79 notebook charges up my battery to 100% the charge light turns blue and after 1 minute cuts off and requires restarting to start charging again


Try removing your battery and power on your computer with your power cord only. If you have no problem with the power cord alone, then you need to replace the battery.

I hope this helps!

Measure the voltage at the terminals of the battery in the laptop. If there is no supply then the power section in the lap tops main board is faulty and needs a check.
However if there is voltage then the battery must be checked if this has failed to charge and is defective. check if the cord from the adapter is not short as it will result in DC power cut off.

Hi, I have a 1.5 yr old gateway NV52 laptop that has stayed in sleep mode for two days...I've tried turning it off and cutting back on but it is still in sleep mode...please help


Hi aiomason.

Remove the AC cord and the battery from the notebook. Re-attach battery and AC cord and power up the notebook. This will clear the Ram memory and force the operating system to "Cold Boot", in other words start the operating system loading up from the beginning instead of resuming from Ram the last time it was active. This proceedure should restore your Gateway Notebook to normal operation. Post back your results and good luck.

If it keeps connecting and disconnecting, it could be either the power adapter or the motherboard, but chances are it's the power adapter (and that's the cheaper solution too). You can usually get a new power adapter for $15 or $20, and that should take care of your problem.

No power to my gateway m-6750 lap top. Have been


Hello,


First use the following steps:

1 Disconnect the battery and the charger
2 Let it sit for 1-2 minutes.
3 Press and hold down the power button for 30 seconds.
4 Connect the charger (don't connect the battery yet) and try to start by pressing the power button.


If everything remain same, check the charger with a multimeter and match the voltage output with its specs.

If the charger is good, then there can be some problem with the DC jack (where you connect the charger).


Thanks

I have a gateway that has been having a dc jack issue. It started to not charge when the it was plugged in, I went through several power cords just to make sure there was nothing wrong with the power...


I have been living with this problem for 5 months now.
The first thing I suggest is to plucg in your laptop then pull the cord under your laptop tug it towards you if you are able to obtain a connection use your laptop to hold the cord. Thats what I am doing now
If that does not work find the spot where you can connect ( by tugging cord back and forth or up and down) and hold the connection with tape or a clamp.

MT6451 Display will not work.


Hello

It sounds like your AC cord or the female plugin soldered onto the motherboard has gone bad and will no longer make a connection to charge the battery or power the laptop on.

You would have to try a new power cord to find out which is the problem. If the cord fixes it, then it was just a bad cord (as you said it gets very hot, this maybe a sign of a cheap cord that has gone defective).

If the cord is not to blame, then the female plugin is loose and there is little you can do unless your an expert at soldering.

Jack is loose where charger plugs in


This same thing is happening with my acer laptop. I sent it to the company about 3 months ago, and it happened again. I really need my laptop and cant take a month without it. I advise sending it in to be fixed to your laptop company.
Good luck (:
