Sony VAIO VPCEC1M1E

This laptop is part of the Sony VAIO brand. Sony made computers in the 1980s, but temporarily stopped to focus on mobile devices. In 1996, they began making computers again under the VAIO brand. To find the model number of your Sony VAIO computer, look at the bottom of the laptop computer. This computer is defined by Sony Support as an 'older model', so the computer should carry both a PCG Reference, which has the format 'PCG-#####x', and a model number, which is formatted like this: '#########'. The PCG reference refers to a group of similar products, while the model number identifies the exact model of laptop. The model number can be found on a sticker located on the display frame or above the keyboard. The PCG reference is on a sticker on the underside of the computer, or sometimes behind the battery if the battery is removable. Support for this model may be difficult to find from the manufacturer, however, since it is an older computer.
