I was doing some work on my computer and then I left it with the power cord on and then after a while I found my macbook with no power. I tried unpluggin and plugging it or reset it by pressing the power button for 10 sec.... nothing seems to work.

That is odd. I have had a fantastic experience with my MBA so far. The good news for you is that, since you have a MBA, you are probably within the 90 window in which you can seek unlimited complimentary support from Apple.

Is it the round, puck-shaped power supply? These are prone to failure; cords usually go bad. The brick-shaped power supply develops issues at the plug where it is inserted into the computer. In any event, your best source is Ebay. Get the computer year and model number and do a search. Sometimes you'll find old computer stuff on Craigslist. Buy two if you can find them and keep one as a spare. Better yet, since you are using a legacy computer with an old operating system, transfer your data to a portable hard drive and update to a more modern Macbook. 2007 models go for $100 on Ebay and they work with modern operating systems, such as OS 10.6.8 and the latest browsers.
could be a number of things including the power block faulty, a break in the power lead, the power regulator in the macbook or even it's just plain old dead. if the macbook lights come on when it's plugged in and nothing else happens when you press the power button, odds on it's just dead.
Make sure that the power cord is plugged into a working outlet, that the prong section is connected with a clean contact to the brick, that the magsafe connector and port are both clean. Remove the battery. Now power on the laptop with the power button.
If this does not work, attempt to reset the NVRAM (http://support.apple.com/kb/HT1379). If this is still not working, you can disassemble the machine and remove the upper part of the bottom case (lifting the keyboard section, and try to reseat the keyboard connection to the logic board. This cable is what allows the power button to turn on the machine. If this fails to fix it, then you have either a bad i/o board, or a bad system board, or a bad power cord.
Follow the steps below and it should solve your mac problem..
Disconnect any devices connected to the computer including printers, hubs, and third-party keyboards or mice, and test the computer again by trying to turn it on.
If you're using a MacBook or MacBook Pro, check the battery level. Press the small button on the battery or on the side of the computer. You should see lights indicating the battery's level of charge. If you see just one light blinking, the battery needs to be recharged. Use the fluorescent pen computer with the adapter connected to recharge the battery.
Unplug the power adapter from the electrical outlet and from the MacBook, MacBook Air, or MacBook Pro. Wait one minute. Plug it back into the wall first, then to the computer. Make sure the electrical outlet is working by plugging in another device (such as a lamp). When you plug the adapter back into the computer, the PowerBook G4 Battery 15" power adapter LEDs should light up green or amber.
Inspect the MagSafe port on the computer for debris, such as metal stuck to the magnet in the port, which might prevent the connector from seating properly. On the adapter side, look at the DC connector for dust or other debris and check whether pins are missing, bent, or stuck down. If you find any of these to be true, see Apple Portables: Troubleshooting MagSafe adapters for instructions on cleaning the adapter.
Make sure you are using the adapter that was designed for your computer. If you aren't sure or if you need a new adapter,learn which adapter is appropriate for your computer.
Press the control key, the command key, and the sony vgp-bps13a/b battery power button simultaneously and hold for three seconds to try to restart the computer.
Reset the PRAM. After pressing the power button, hold down these keys simultaneously: Command-Option-P-R, until you hear the startup chime at least one additional time after the initial startup chime.

On the MacBook Air, press (left) Shift-Control-Option along with the power button once. Note: You must use the keys on the left side of the MacBook Air keyboard.
If you recently installed additional memory, make sure it is correctly installed and is compatible with your computer. Remove the new memory to see if the computer starts up properly without it.
If you are still unable to start up your computer after trying each of these steps, schedule a service appointment with either an Apple Retail Store or an Apple Authorized Service Provider.

you can alternately reset SMC by disconnecting both power adapter and main battery, and
holding down power button for 5 seconds.
