Question about Dell Latitude E6400 Laptop
This does happen on some of the chargers. Most times if you unplug power can let the battery drain all the way and plug back in it will fix its self. If this does not work it can be motherboard issue or adapter. See if you can try another one and if not it would be motherboard. When you try another adapter make sure it is at least 90 W. Hope this helps

There are at least four possible causes for this error - (error 3600-0749, right?).
First one: the adapter is faulty. You would need a tester to determine whether the adapter is indeed supplying power. Dell will send you a replacement adapter if the warranty is still good, or you can find one online (model PA-19 PN402, 230W).
Second: one of the DC jack solder points on the motherboard cracked. You may see the error disappear by "wiggling" delicately the jack in the notebook. You either need to call Dell tech support and have the MB replaced for free (if under warranty), at cost - in excess of EUR 400 - or the jack may be resoldered, which will void the warranty and requires experience in disassembling and reassembling the laptop.
Third: motherboard is otherwise damaged (voltage regulators, buffers, and so on). Diagnostics must be performed by a Dell technician; replacement policy as above.
Fourth: you may have problems with the BIOS (if it is a brand new unit), solvable by upgrading - Dell will suggest this avenue first if you call tech support, anyway, so check you've got up-to-date BIOS and drivers.

The AC adapter needs to be replaced. You can buy one from Dell for about 100-200 dollars. If your laptop is still under warranty, the charger is often covered under the same warranty as the laptop and should be replaced under warranty if applicable. You may also buy a third-party charger off of ebay or amazon much cheaper, but this is not recommended. If you do consider a third party charger, make sure that it has the same wattage, voltage, everything! Good luck!
