Re: no power on my nc6120
You are most likely dealing with a laptop whose power supply has blown/quit working. You are probably going to have to get someone to change out your power supply, or you might just have to buy a new laptop, depending on how old your laptop is, and how much it will cost you to replace the power. Of course, if your laptop is a newer one, then I am sure it will be worth it to get the power supply fixed or replaced. And if it is even so new as to stll have the warranty valid, you can probably get the computer's manufacturer to fix this at no cost. If warranty is still valid, contact them for details. But keep in mind that computer manufacturers also have limits on warranties, and if you spilled something on the screen or inside the laptop, or you are at fault with any other negligence, the tech support people will detect this, and will probably tell you that your warranty is not valid against spills or negligence, thus requesting you to pay for the repair. I hope this helps.

Try another AC outlet, try another cord/charger of the EXACT same power spec. Has the AC jack in the computer been damaged by pulling on the cord? Power surge? With a multimeter, verify DC volts at ac cord plug. Is the Laptop usually left plugged it when not in use? Do you shut it down and unplug when not in use?

Laptop batteries power a laptop when it is not connected to an electrical outlet. If the laptop battery fails to charge when the laptop is plugged into an electrical outlet, the battery is likely dead and needs to be replaced. Unfortunately there is no way to fix a dead battery. However, while a dead battery is the likely cause, it is not the only cause. The AC adapter may be broken, in which case the battery won't charge, or the battery contacts may be dirty and need cleaning. Prior to replacing the battery, perform simple tasks to ensure a dead battery is the cause of the problems.
1.Power down the laptop. Gently pull the AC adapter from the side of the laptop for removal.
2.Place the laptop in front of you, bottom side up. Locate the battery release mechanism. This can be a button that slides or needs to be pushed to unlock or release the laptop battery from the housing unit. Press or slide the mechanism. Slide or lift the battery from the battery bay for removal.
3.Insert the AC adapter into the side of the laptop. Power on the laptop. If the laptop does not power on, ensure the AC adapter is securely plugged into a working electrical outlet. If the electrical outlet is working and the laptop won't power on, the AC adapter is not properly working and needs to be replaced. Remove the AC adapter.
4.Dip a cotton swab in a small amount of rubbing alcohol. The cotton swab should be damp, not dripping wet. Lightly rub the dampened cotton swab onto the battery contacts and battery bay contacts to remove dust, buildup and grime. Allow the contacts to air dry.
5.Align the battery over the battery bay. Either press or slide into place. A clicking or snapping noise produced from the locking mechanism will confirm the laptop battery is securely locked into place.
6.Install the AC adapter. Allow the AC adapter to fully charge the battery for 8 hours.
7.Remove the AC adapter. Power on the laptop. If the laptop does not power on, the battery needs to be replaced.
1.Plug the Inspiron's AC power cord into a power outlet and try to power on the laptop again. By far the most common cause of a laptop's not powering on is a dead battery. 2.Plug the AC adapter into a different outlet to check for a "dead" outlet. If you have the cable plugged into a surge protector, plug the cord into a different slot on the surge protector or "bypass" the surge protector by plugging the cable into an electrical outlet. If the Inspiron now powers on, replace the surge protector or have an electrician examine any "dead" outlets in the home. 3.Open the battery bay on the underside of the Inspiron by sliding the battery bay latch release lock upward and the battery bay latch release to the right. Once both latches are released, the battery bay should open. 4.Remove the battery. 5.Purchase a compatible replacement battery for laptop. Be aware that using an incompatible battery can cause damage to your computer. If you have any doubt as to compatibility, the best option is to purchase the replacement battery directly from your laptop's manufacturer. 6.Install the new battery by following the battery-removal procedure in reverse order. Once the new battery is installed, try again to power on the laptop. If there is still no power, seek professional repair advice.
We need to know what is defective and what is not.
Remove the battery from the laptop.
Plug the power cord to the laptop and plug it to the wall power outlet.
Now, without the battery, turn your laptop ON.
If it powers ON without the battery, then your battery is completely dead and needs replacement. If the problem is still the same, then it should be a motherboard problem considering that you have already confirmed that your power cords are working.
Try your luck. Post feedback if you need further instructions. The point is, you need to know if the battery is dead by removing it first then connecting your laptop directly to the wall power outlet. You can connect it to a Surge Protector or Automatic Voltage Regulator for safety purposes if you want.
If it was not pluged in to a power outlet and the battery was dead yes, but it should power up if its connected to a ac outlet. You laptop may be in sleep mode try resetting it by taking out the battery and letting it set..
