Hi your AC adaptor might be the problem. I repaired about 7 adaptor charger and I can you that this is the problem. Lot of time this unit is always be drop and the enternal parts such as transformer wiring solder to a little board are all broken off and no connection to the transformer or to the board. Just buy or order it to dell web site and cost is depending to the model of your laptop. I believe the cost is under $100.00.

DELL LAPTOP INSPIRON 6400 MY LAPTOP BATTERY IS SHOWING STATUS ( UNKNOWN ) ON WINDOWS & ON BIOS IT SAYSS BATTERY NOT INSTALLED


Here are my recommendations for this issue:

1. Reseat the battery.
2. Remove All External Components
3. Check the battery connectors on the battery and the system. Examine the connector on the battery and the system. Make sure that there is no physical damage and that it is clear of debris.
4. Remove All External Components
5. Try a known-good battery in the system, if available.

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.

No Power : Dell Inspiron 6400


the very first thing that u can try is that try with the different ac adaptor and the battery if u have and if it doesnt the same thing then definately u have to replace the motherboard and if the other ac adaptor and the battery works then replace the ac adaptor and the battery but what i suggest u is that u should replace the ac adaptor and the motherboard both at a time and it will be fine and for that u dont have to worry about ur data in the computer cause replacing the motherboard will bot loose ur data.......

Ac adaptor use drains batteries


Hi,
As a system gets a little age on it, the battery naturally decays. Also, each time you plug the ac adapter into the laptop, the adapter connection on the motherboard becomes a bit looser on the solder points, all of which contributes to the symptoms you describe.
You could try a fresh battery.
The standard rule is a battery is wireds to last between 500-600 cycles, then it's dead. They claim it's a safety feature.
Good luck, hope that helps.
Thanks

Dell inspiron 6400 battery pack problem


If your battery pack does not charge and power is being supplied by the AC adaptor to the computer then i would guess the cells are dead or maybe the connection to the battey has been damaged in some way. The best way to check is take it to a computer repair shop or spares shop and ask them to try it with a new battery if the same problem occurs then it is the connection or the ac adaptor. My solution would be try a new battery before you buy it to check if it is the problem.
