Serial Number Of Laptop Identify Origin Product

For a new laptop, you can take all the data and information into account through the internet or the instructions attached

. But for the second hand market, there are full of different qualities and models. If you are a green hand about the second hand market, youd better find a veteran to help you. Like this Gateway PA-1650-01 AC adapter, there are some skills to pick one.

Last time we talked about how to check the surface and the keyboard. This time, more hints will be listed below. Then you can recognize the tricks of the salesman.

First, check the laptop's battery. Because laptop battery applied to a special welding technique, if taken apart, its difficult to restore it. At least, there will be some scratches left by hand opening. That is the same to the adapter like this Gateway PA-1650-01 AC adapter. Most new laptop battery should be no more than 3 times charging and the power of the battery should not be in more than 3%. For second hand laptop, the battery is used for many times. So you should not have high expectation of the battery as a second hand laptop. So dont be misled by the words of the salesman.

Second, have a look of the laptop screen. The LCD screen is easy to check for the scratches and the marks are clear to see. The LCD screen aged as time passed. So the best way is to watch a movie and judge the brightness, the color and the contrast. Youd better check the brightness for some salesman will turn the brightest level when you check the screen.

Third, the serial number of the laptop is the identical. Like the ID card of the laptop, you can identify the basic information of the laptop. Generally laptop's serial number is located on the bottom of the label. We have to carefully check whether they have had to be altered, to be re-posted at the scene.

As I finally have this gateway laptop for my friend. And this Gateway PA-1650-01 AC adapter has been opened before. Whatever, it has been used for one year. And its not old enough to retire.
