Dell XPS M170 does not recognize the 130 W adapter

First of all make sure that there is a wireles adapter on your laptop.
There are some XPS M170 Models without one.
If you have one, we can try to solve the problem?
1. Make sure that the driver of the Wifi adapter and the Chipset are propertly installed. Try to download the newest driver from the dell web site accordng your os
2. If there is a third party conection software like Conection manager or else, deinstall it an let windows manage your networks
Hope this helps you. I will need a screenshot and some further descriptions in order to solve the problem if the 2 solutions above dont help.

2000-0142 and 2000-0146 are hard drive SMART errors, indicating the HDD will fail.
To boot message about the AC adapter was a BIOS level message that normally appears when a Auto/air ac adapter or other 65 watt ac adapter is used to power the system.

The adapter could be faulty or has failed slightly and is below the operating limits. This means you probably need to replace the power adapter.

You should probably do as it says and check your power adapter which apparently has gone bad.

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.

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.

-check the system battery information and charger information of the computer; restart the computer, while the computer is booting up, press F2 repeatedly; check "battery info"
-if it stated ac adapter = unknown device ; update the BIOS (-visit support.dell.com
NOTE:other computers may have different BIOS, if it is not the same you may have to consult manufacturer
-click on drivers and downloads
-click or choose by service tag
-download the BIOS and install it on the computer)
-check information after updating; if same message AC adapter = unknown device; call manufaturer for a replacement AC adapter, if status has changed it is a battery problem or motherboard, contact manufacturer to test battery

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

If you don't get any errors when you startup on battery then all you have to do is call Dell. Get work order number and send them the laptop and adapter. They are very fast. I sent a laptop to them last month and I had it back in 3 days! I was surprised.

The AC adapter has a small wire in the center of the connector to the system. This sensing wire, if bent or broken will cause the error you mention.

Check the inside of the connector, since it is new, you can call Dell 800-624-9896 for a replacement adapter.
