Question about Dell Latitude D400 Notebook
When i connect ac/dc adapter to computer, the led indicator for charging starts flashing. it flashes 5 times/brake/5times/brake......
batery is completly empty, so i can't even turn on my computer.
Is it a batery problem or is it charger problem or is there anything else that could cause that problem.
Thank you for your help & sorry for bad english
Your english is actually above average!
For you to get the best solution to this problem, I'll suggest that you should just try and get a friend, or a technician that has a charger of the same type, i.e a Dell Laptop Charger, to test it with. Now, if it still doesnt work, then you can try and swap the Battery with a working one also. All these are just to clarify things for you and to teach you the easiest way of troubleshooting it yourself.
Then If the new charger charges it, it means you just have to get a new charger, and if the Battery swapping is the one that works, then you might have to get a new battery too.
At the same time also try this quick solution :
Remove the battery from the back of your laptop, and power the laptop without the battery inside. If it works this way, then just try and get a new battery instead.
Hope this helps you out!

The battery charger can be tested using a multimeter, the contacts of battery charge connector must read +_.5V on prescribed voltage.
Faults that can cause the problem.
Faulty AC adapter.
Faulty battery (in this case it will start with no battery inside)
Faulty DC socket on laptop motherboard.
Test the charger, if voltages are wrong replace it, if voltages are fine have the motherboard replaced or repaired, or replace the laptop.
