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, but discontinued their personal computer sales again in 2014, selling their PC business to Japan Industrial Partners Inc.
All Sony computers have a PCG reference number, such as PCG-71811M on this computer. However, this number should not be used as an identifying number, since it describes a group of similar products, and not a specific model. To identify the exact model of Sony Vaio computer that you want to repair, you will need to find the product name and serial number. The product name can usually be found on a sticker located on the display frame or above the keyboard. The serial number is on a sticker on the underside of the computer, or sometimes behind the battery if the battery is removable. The product name for this computer is VPCEH2K1E.
On July 7th, 2020, Sony withdrew drivers and support for all computers running Windows 7 or earlier operating systems. Because of this, almost no technical information about this computer can be found online. If you own this computer, feel free to add information about its specifications (size, processor, memory, etc).
