Hi,

Make sure that you are using the correct power supply. Some have an extra pin in the middle for the laptop to talk to the supply. Make sure that you are not using the typical type that do hot have the extra pin.

Just call Dell, don't take it back to Best Buy or anything (that's where I got my Inspiron 1565). They will put you through a couple troubleshooting items and decide whether it's the AC adapter went bad or if they have to replace your motherboard. It's all free since they have a 1yr hardware warranty.

When you received the system as out of the box and you get this message "The AC power adapter wattage and type cannot be determind" let the Dell tech service know that they sent you a wrong or incorrect type of AC Adapter.
If this message not was not appearing before it just happened recently try to download and install the latest BIOS version from the support site.
If all fails remove the batt and check if laptop can work with AC adapter alone, because issues like AC not determine may not charge the battery and laptop may not work with AC as well, maybe laptop is already running on battery power.

SOURCE: the ac power adapter wattage and type cannot be determined .

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.

AC power adapter wattage cannot be determined


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!

Certain models talk to a chip in the adapter, sounds like this one has gone bad. At this point you can live with, buy a new one or pick up a used. This is a fairly popular model and you should be able to locate one from a dead laptop.

Access the manufacturer's web-site for your DELL XPS laptop:

http://support.dell.com/support/downloads/driverslist.aspx?c=us&cs=2684&l=en&s=pub&os=WW1&osl=en&catid=&impid=&SystemID=XPS_1730

Find the Dell XPS Service Tag on a sticker on the bottom of your laptop.

On the above page, click "System Configuration", and enter that ID,
to get a list of parts, including the AC power adapter, that was shipped with your computer.
