Problem with AC plug in on the back of the computer

When I plug in the ac power pack into the ac in spot on the back of the computer it does not connect and power up the computer. Sometimes it will switch from battery to power but will not stay connected for more then a few seconds.

Either your adapter is going out, you have a broken wire in the cord, or you have a broken solder on the computer connector.

I dont remember power on password for hp nc4400


The power-on password prevents use of the computer until the password is entered. The
setup password prevents unauthorized changes to Computer Setup. To clear the
passwords, you must remove all power from the system board. If you do not know the
passwords, use the following procedure to clear the password:
1. Remove all battery packs.
2. Disconnect the AC power.
3. Remove the real-time clock battery.
4. Wait thirty minutes.
5. Reconnect the AC power. DO NOT INSTALL THE BATTERY!
6. Restart the computer. During Power-On Self Test (POST), a ? 162 System Options
not set? message appears.
7. Shut down the computer, then disconnect AC power again.
8. Replace the real-time clock battery.
9. Install the battery pack(s).
10. Reconnect the AC power.
11. Start the computer.
12.It should work....

Dell latitude 610 AC adapter issue or battery pack issue or both?


It could possibly be the power jack that is inside the computer. This item is typically soldered onto the motherboard and it is what your ac adapter plugs into.

I have ac adapter plugged into the wall, and into the computer, the charge pack light is green, the battery is in the computer and the computer won't turn on at all


You probably have a bad or loose DC jack on the laptop:



Problem symptoms:

  1. Laptop randomly shuts down without any warning.
  2. Power LED and battery charge LED start flickering when you wiggle the power cord or the AC adapter tip on the back or your laptop.
  3. The battery will not get charged.
  4. When you plug AC adapter, the laptop appears to be dead and there is no LED activity at all (DC-IN jack on the system board is broken).

Computer was on AC power. Left unattended it shut down. Would not wakeup. Shut down fully, it would not come back up. Get a 2 short beep code. Invites an F1 to go to setup. Won't go to setup. Screen then...


Can you tell if your AC power cord is working? (Is there a light on the computer that comes on when it's charging?) If the power pack went dead, your battery could've died and now you get no power to the PC which is why it won't boot up.

To test, take out the battery and plug the AC cord in and try to boot up. If nothing at all happens without the battery, then your power cord or power pack is dead, and you just need to replace it.

Not charging


Remove the primary battery pack and travel battery pack (if applicable) and plug the computer
into an AC outlet using the AC adapter. If the computer starts up, one of the battery packs
may need to be replaced.

if the computer does not start with a/c power connected. ensure the power outlet is providing power, otherwise you problem may be the motherboard, cpu or memory. please provide more details (ex. lights on and color, any beep secuences heard, procedure attempted, age of computer, how the problem came to be)

Shut off and won't come back. It's like it is dead.


follow this procedure:
1. unplug the ac adapter and keep it unplugged.
2. Remove the battery and keep the battery unplugged.
3. Hold the power button down for 15-20 seconds(Nothing will appear on the display and none of the lights will light up)
4. Release the power button and plug in the ac adapter ONLY. (A power indicator light should be lit on the ac adapter when it is plugged in)
5. Normally power on the notebook.
6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
7. Plug the ac adapter back into the system, the battery charging indicator light will light up. If the battery indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.

ASUS A8JP Will Not Power On


"When the charger is connected to an AC source, the green LED shines steady and bright."

are you talking about the led on the AC-adaptor? cause if its that led that dims down, its a defective ac-adapter (even tho you still might not believe me). replace it and try again.

how would you know that the battery is fully charged?


please rate my solution after you have tested if it works out for you :)

No power


In my searching for another problem, I read a lot of postings about Toshiba laptop computers and faulty power plugs (at the spot where you plug in your AC adapter into the computer). It seems to be some kind of universal problem with Toshiba and I think there was even a recall a while back because of this. I do not know if this is your problem, but it certainly sounds similar.

The computer does not seem to be charging up


Hi,
I am a Dell Certified System Engineer(DCSE)

try taking out tthe battery and then try powering the system only on ac adapter connected
if it doesn't power on only on the ac adapter make sure that the port on the system where you plug in the ac adapter for any kind of bent or broken pins
if the port is ok then get your ac adapter replaced.
