Reason for being junk: While I have confirmed operation and initialized it, the battery is significantly degraded, so an AC adapter connection is required. The power will turn off within seconds if the adapter is disconnected. Also, it's better to connect directly to a wall outlet rather than using a tap. Everything in the photos is included: the main unit, keyboard, and an AC adapter purchased separately from Amazon. This is a used item that was used normally, so there may be minor scratches and dirt. Please understand this before purchasing. The specifications are not high compared to current models. Microsoft Surface model 1796, a laptop with 128GB of storage. - Brand: Microsoft - Model Number: 1796 - Processor: Intel M3 - Memory/Storage Capacity: 4GB/128GB - OS: Windows 10 ※ Although it may be possible to upgrade to Windows 11, I think it will be difficult in terms of specifications. Thank you for viewing.
