Question about Dell PC Laptops

1 Answer

AC Adapter The AC adapter for my Inspiron 6400 stopped working (green light on adapter box would not come on and laptop would not register that it was plugged in). I replaced the adapter and am already experiencing the same problem (within a week). Is it possible that my laptop is frying the ac adapters?

Two possible solutions are present; one is that you have terrible luck with said adapters. The other is that you're using adapters with too much or too few milliamps or volts. If the specified rating on the adapter doesn't exactly match the power consumption for the computer, then it will become strained or vice vera and it won't work.

Ac power jack not seeing power cord inspiron 6400 when I plug in ac - the light does not light to show ac power and because it is dead I can't turn it on.


YOu are having issue with the motherboard. ther might be a short circuit or bad part on the motherboard that might have caused it not to detect the ac adapter and system will not power on. You need to have motherboard replacement.YOu can contact dell for repair options.

I have a dell Insiron 1526. we thought it was the power port and changed it. they charger shows a green light when plugged in and when you add the computer it starts blinking but the computer will not turn...


try to use a different power adapter or try your ac on a different system so you can determine if the issue is with the ac adapter or on the system. if the power adapter works on a different system, try to remove any external device as well as the ac adapter and the battery. while the ac adapter and battery is out, press and hold the power button for about 15seconds. then reconnect any power source and turn on the system. if it still doesnt turn on, remove memory, expansion cards, hard drive and optical drive then turn on the system. if it's still not turning on, the motherboard is faulty. but if it do turned on, reconnect the removed components one by one so you will determine which component is causing the issue. hope it'll help. good day. =)

AC adapter not recognised


Try charging the battery on one of the other dell's.
If the unit runs for any lengh of time, it is not the motherboard.
It could be the A/C adaptor jack on the side of the unit.
Log a complaint will dell's customer care.

I had the battery not recognized on boot up. then


the Dell AC adapter has a sensing pin so the bios can determine the wattage of the adapter. If the system cannot ID the adapter, the battery charger circuit is disabled. You'll need a functional DELL ac adapter to get the battery to charge

Inspiron 1318 but when I connect the ac adapter cpu 100%


It is a possible AC adapter problem. However please try to download the BIOS firmware update from Dell's website and see if problem exists. If it does, then try using another AC adapter (preferably the same model and make) and see if the same problem occurs. Please reply if same issue occurs.

On the issue with th ebattery on the 1521 inspiron. Took battery out and plugged in still will not power up. Could it be the adapter as well?


On the ac adaptor, look for a green light that will turn on when you plug it into the wall outlet, if its on that means the ac adapter working. If you get a green light on the ac adapter but then the green light goes away when you plug it into the laptop then that means the laptop has a bad motherboard.

If you plug the ac adapter into a wall outlet and get no green light then that means the ac adapter is bad and you would need to get another one.

The little green light on charger goes off when i plug it into Dell Inspiron 6400, the charger works fine


Unplug the battery from the laptop and then plug the AC adaptor into the laptop. If the green light still goes off then your motherboard is shorting out the adaptor and the motherboard needs to be replaced.

Hi,
1. Shut down the system, remove the battery and the Ac adapter from the computer.
2. Press the power on button for 10 seconds
3. Reinsert the battery
4. Power on the computer and as soon as you see the dell logo press the f2 key a couple of time
5. Using the up down arrow keys , go to the option that says battery info. If there is an error message listed kindly post it back

6. Otherwise shut down the computer reconnect the ac.adapter and check if the problem is solved

Also the battery has a diagnostic lights on it , remove the battery from the computer and press the button on the battery a set of lights would glow. If they are steady and come in a series the battery is good , If some lights are missing the battery is bad and may need replacement
