How do I find the model number of my dell?

I know its a dell. but I need to know what the number is. my mom needs to know and I told her I would help. HOW DO I FIND OUT THE MODEL NUMBER OR WHATEVER IT IS CALLED?

please help

If its the serial number of the computer, there should be a tag on the back or bottom with the numbers you need. But I going to guess that you're looking for a different number

I'm going to guess that its the IP address you want.

Here's How:

1. Click the Start menu button on the Windows taskbar.
2. Click Run... on this menu.
3. Type cmd in the text box that appears. A command prompt window launches on the desktop.
4. In this command window, type ipconfig /all. Details are shown for each of the computer's network adapters. Computers installed with VPN software or emulation software will possess one or more virtual adapters.
5. The IP Address field states the current IP address for that network adapter.
6. The Physical Address field states the MAC address for that adapter.

If this isn't what you're looking for, can you more clearly describe what it is that you need?

You should be able to locate the model number directly on the bottom of the laptop, like Goran said. All computers are different so you just have to look for it.

There's usually 3 spots with numbers on the bottom. One should be your Windows or operating system key. The other contains the serial number (s/n). The the third contains the model number among other key numbers. Sometimes it labeled as model # or reg. #.

If you can't find the model number on the bottom, but you can locate the serial # go to the manufactuers website and enter the s/n that should bring up the model number and any other information needed.

If its the IP address follow Goran's steps and you are good to go.
