Your DC Jack Is Most Likely Failing From What You Describe....
The DC Jack Is The Port Where Your Charger Cord Plugs Into..
If Wiggled Enough, It Will Pry Loose From The Motherboard And Eventually It Will Begin To Short Out The Power, If Left Unrepaired, It Will Eventually Lose All Means Of Charging/Powering On Due To The Solder Being Burnt Away From The Positive Pins That Connect To The Mainboard....

You Might Want To Test Your AC Adapter With A Multimeter For Positive Power and Correct Voltage .. Sometimes A Broken Cord Will test Good If The Break Is Making Contact when testing....
So When Testing the cord... Slightly wiggle it to see if indeed there is a break in it or not...

Can i use this lap top with plug in and not a battery?? where is the plug in?


I BELIEVE so. Some laptops require the Battery to at least be in the laptop, whether they are good, or not.
Others will allow the laptop to run off of the AC adapter (Charger), with the Battery not installed.

Gateway Support > Gateway MD26 series of Notebook PC's > Main Support page,

http://support.gateway.com/us/en/product/default.aspx?tab=1&modelId=2364


Click on the - Support Documents - tab.
(Drivers / Applications / BIOS / Patches / Support Documents / etc)

Click on - Product Views - in the list.
Click on - Left View
Power connector

This is where the AC adapter (Charger) plugs in.

Examples, (Note US and Europe have different power plug ends),

http://www.batterytech.com/products.aspx?category=ac_adapter&brand=gateway&model=MD2614U&pid=AC-1990111

[The laptop uses DC electricity. Just like the Battery it has, and flashlight batteries. DC Voltage.
The AC adapter (Charger) converts your household, or business, electricity from AC to DC.
(19 Volts DC. In comparison two D cell flashlight batteries store 3 Volts DC ]

Charger light goes out when plug in computer


it could be that the connection jack on the mainboard has been dislodged from the solder joint, common among Gateway comuters and HP units too. is the DC jack loose from the notebook ? if so thats the issue it seems. You will have to bring it to a computer person to resolder. if not and youc an do it yourslef, save money -- but be careful not to damage anything on the mainboard.

My computer won't turn on or charge.


You need to diagnose the problem.
>First try to take the battery out of the computer and just use the charger to make computer run.
>If it turns on it means that the battery is what's causing the problem.
>But, if computer cannot run using the charger/AC Adapter then it means that we have a problem with the charger.
By doing this diagnostics you know which part to replace.

WAS MISSING CHARGER, but was running on battery. will not charge battery or power up, no lights. Battery went dead MT6821 GATEWAY


Hi,

All you need to do is be sure whu will need to replace both.

If the problem is with either the charger/battery you will need to figure that out first.

Please have the battery charged of your laptop, and try using the laptop only with the battery and without the charger, If it works fine you will have to check the charger now.

In order to check the charger, please take out the battery from the laptop, now connect your charger to the laptop and try switching on the laptop. If it does not work then your charger is faulty.

You can purchase the accessories online at various portals. I am providing one of the portal information:

Charging problem


Welcome to the world of the DV9000s....if it isn;t a motherboard issue, it is a power issue. Do not trust either the power cord or the battery or the computer for that matter because I have seen over and over that all three components are not playing well with each other in these systems and the DV6000s. It could be very possible that the battery has bad or damaged cells in it and will probably run fine for a while and then crash suddenly. That is because it is using the good cells and then a bad cell kicks in and....nothing.
Take the battery out and just hook up the charger, if it runs fine for a couple of hours just on the charger then I suspect there is no problem there, chargers tend to overheat, then their voltage reulators will start to fail and then the battery is discharged or over charged and then everything fails.

Toshiba laptop won't start up


Try this:
  • remove battery
  • replace battery
  • restart
Then:
  • with charging cord plugged into computer and wall restart
If it starts on the battery the computer has reset itself-- you're good to go...

If it starts on the wall charger but not the standalone battery... the battery is the problem.

If neither works replace the charger cord.

Good Luck

Computer runs off battery only not the power cord (battery is brand new)


You have a serious problem with the power and charging circuit. Normally if the battery is faulty the laptop can function with the power adapter plugged and running off the mains.
If a techo cannot fix without replacing the motherboard, then replacing the motherboard might not be a cost effective solution.

You salvage the hard drive by inserting it into an USB hard drive adapter case and use it as an external USB hard drive.
Sorry about this, you have very few options.

No signs of power on my gateway mt3705


The power supply provides only 48V (or what ever is listed on the back) but the computer breaks out +12 -12 +5 -5 etc and if that power regulator is damaged it will not come on.
Remove the battery and unplug, hold the power button on for 2-3 minutes, plug in ONLY the power cord and press the power button.
Most likely if you don't get any text on the screen the internal power regulator/converter is damaged.

Possibly Need a New DC Jack In Your Laptop... the DC JAck Is The Port Where Your AC Adapter Plugs Into...

Though You SHould as well Check For Proper Power To Your CHarger Cord.. Not all AC Cords That Have Their Lights On Are Able To Charge...

To CHeck If It's The DC Jack... Remove Your Battery..... Plug In the AC Adapter Cord... Power On... If You Get No Lights/ No Power/ No Fans Etc..... It's Your DC Jack
