Sounds like a issue with your new ac adapter, or you can be dealing with a broken power pin, This is very common in Laptops, The Power Pin is a connection between your Ac adapter and the motherboard, often this pin is accidently broken causing no contact between the power port and the mother board causing your power issue. If it is the power pin, it will more than likely need professorial work, because the pin needs to be re-soldered back onto the mother board. Total cost for the power pin averages about 40 bucks and most techs will charge around 200 for the labor.
Hope this helps, take care and have a great week.

There could be many reasons for your problem from shorting something out while the motherboard was exposed to over heating the area at the power jack. My first and simplest suggestion would be to remove, and re-seat the memory modules. Are you sure you have good solder contacts on the jack you replaced?

When i connect my adpater to my laptop it doesnt charge my laptop even thow the light on the adapter is green


I'm not sure I understand your question. Can you please be a little more specific.
If your computer is showing green light and it powers up it would mean that your battery is no good and you should start looking into purchasing another battery. If that does not answer your question please feel free to leave a message and I will try and do everything I can to assist you. Good Luck!

eventhough the light indicator on the ac adapter is still working, it doesnt mean that the ac adapter is still working fine..

  • the problem could be the ac adaptor itself, the dc in port of the computer or maybe the motherboard.
if the computer is still in the warranty, sony will cover the battery, ac adapter replacement, or process repair if needed. you can call them at 888 476 6972 or 239 768 7669

Not charging


which green light?

light from the ac power adapter or the light from the battery?

if ac power adapter you are referring to try a diff power wall socket if ac power adapter still off then replace ac power adapter alone.

if battery light is off but the laptop works fine with ac adapter alone try updating the laptop BIOS.

if ac adapter light turns off when it plug to the laptop replace motherboard.

Battery has gone dead. When I plug the A/C cord in the light on the charger immediately goes out and won't charge battery.


try connecting ac adapter alone without the laptop, check if ac adapter light will stay green or blue.
try another power outlet using the ac adapter alone without the laptop check if the ac adapter light will stay as green or blue. if all fails replace ac adapter.

if ac adapter stays green or blue try connecting to the laptop without the batt, check if the ac adapter light will stay on, if yes then try connecting ac adapter to laptop with the batt plugin check if the light stays green. if not update the BIOS. if fails replace motherboard.

My Sony PCG-K10 Laptop is not powering up.


Either the ac adapter is defective or the dc connector on the motherboard is bad. I would test the ac adapter with a volt meter and make sure you are getting voltage through first. If there is power then likely the dc jack and someone will have to solder in a new connector

Asus ac adapter will not wrk green light on adapter


First check the wall socket make sure you are getting power, plug a lamp into it for instance. If there is no green light on the adapter then it is bad and you will need to order a new one from your computer manufactor.

Unplug All External Devices Unplug the AC Adapter From the Wall Outlet. Disconnect the AC Adapter From the Laptop Reseated the power cable to the adapter.
Remove the Battery Connect the AC Adapter Directly to a Known Good Outlet, But Not to the Computer Verify That the AC Power Adapter Has a Solid Green or Blue Light.
The AC adapter status light is solid green. The AC adapter status light is solid green.Press the Power Button and Check for POST. Post means if you see the dell logo,remove the battery, plug the ac if still it wont turn on or doesnt have any light,Reseat the Memory if after reseatting the memory still the same problem it might be a bad motherboard.

Sony Vaio ac adapter submerged


If the ac adapter was plugged into the laptop at the time may be bad news. Unplug AC adapter, take out the battery and hold power button for 10 seconds. Then connect AC adapter and hit power. If that doesn't work put battery back in without ac adapter and hit power button.

If neither test works bring to repair center for diagnosis. Best case AC adapter would need replacing. Worst case Motherboard fried.

Thanks
