Faulty dc power jack

please measure the output for your charger,normally they have 19.5 vdc exactly, if they do not measure the adapter is faulty, repair or replace.If the output is o.k the battery can be faulty. Use the software diagnostic coming with the computer, restart the computer HOLD the key f2 or esc depending of your computer model, and make the diagnostic.try again and see what is the result, if the battery is o.k or faulty.God bless you

This could be an AC adapter problem.Use another same rating adapter for teating.Check your ac adater volt and ampere at output terminals using a good quality digital multimeter. If OK, check the battery also. Then only suspect motherboard and power jack. Hope this helps

Take out of your battery, then plug in your ac adapter, see if it works, if no, then you have a faulty ac adapter, you need to replace it; and if yes, then you adapter is ok, the battery or dc jack may be broken.

You have a DC connector problem:

2. Battery will not charge in the laptop.
3. Laptop runs fine off a charged battery.
4. With the AC Adapter connected the laptop appears to be dead.
No power LED or battery charge LED activity.
5. Laptop randomly powers off without any warning.

If your laptop is out of warranty, then you can fix the problem by re-soldering DC-IN jack on the system board. If it

It sounds like either a bad connection on the motherboard or a broken wire in the adapter making intermittent connection.

1. With the power adapter disconnected, do you have a power light? This would indicate the adapter is good and the plug is questionable.

2. Check your power adapter output with a multi-meter.(be sure to wiggle the wires around) If the power fluctuates, replace the plug.

3. If the power is solid, replace the motherboard connector.

Remove the Laptops Battery, Plug in AC Adapter... Is it able to Stay Powered On?? Slightly wiggle the Cord Near the plug end while plugged in... Does it still receive true power??? If So, Its Not Your AC Adapter Or Your DC Jack And You should Look into Replacing Your Laptops Battery...

If You Are Not Able To Power THe Laptop Using Just The AC Adapter When The Battery Is Removed, Then You First Need To Check/Test The AC Adapter using A Multimeter To See If You Have A Faulty Cord... If Cord Is Still Getting Correct Power Through To The Plug Tip .. Then You Will Need To Replace The DC Jack (the port where your AC Adapter Plug Plugs into on the laptop)

You Need To Replace the DC Jack..this involves desoldering the old/faulty dc jack from the motherboard, then cleaning the board, then soldering a new dc jack in place of the old...

But First, Test Your AC Adapter - use a multimeter (available at any home improvement store for under $7)...

Sounds like you have a loose DC jack or a faulty AC adapter. Try testing the adapter with a multimeter (or have a someone do it for you) to see if it's output is consistent. If you wiggle the ac adapter plug slightly when it is plugged into the jack on the notebook and this causes the power to go on-and-off (you should be able to tell by a power/charge led on the notebook) it is likely the DC jack if the AC adapter tests ok.

Prices to replace the jack vary. My shop does it for $65 labor + $15 for the jack on most non-apple notebooks.

Sounds Like From Your Description That You Need Your DC Jack Repaired/Replaced..

THe DC Jack Is the Port where Your AC Adapter Plug Plugs into on the laptop.... THis can be proprietary or non proprietary.... But Either way, the Old Faulty Jack Needs To Be Desoldered and Removed, THe Board Cleaned and a New DC Jack Soldered On.. You Will Then Be able To Power On Laptop With AC Charger and Will again Be Able To CHarge The Battery..
