Surface Pro 3 Junk Item

Purchased new at the time of release and used for about 5 years for drawing. After that, it was occasionally turned on for operational checks, but not used extensively.
It is being sold as junk because the connection with the tablet is often lost, causing the screen to go black, possibly due to an issue with the keyboard. The tablet alone was relatively stable, but that is also uncertain, so please only purchase if you understand this.

The keyboard shows significant signs of use.

The included pen broke due to battery leakage after purchase, and I used a successor product to the genuine one. The pen nibs are slightly worn depending on the pen. The successor pen did not fit in the original box, so it will be packaged separately.
Please note that the pen batteries will be excluded to avoid shipping issues. If you wish to use it, you will need one AAA battery, which you will need to provide yourself.

Additionally, the power cable was announced by the manufacturer to be defective at the time, so I used a replacement of a different type that was switched to later. This also did not fit entirely in the original box and will be packaged separately.

A protective film has been applied to the screen, but it has minor scratches. The back also has minor scratches due to age-related deterioration.
It has been initialized and powered on for operational checks. The login name used was surfacepro and the password was 1234 (please refer to the image).

It will be packed with measures against water damage and bubble wrap, but as it is a junk item, the packaging will be simple. Thank you for your understanding.
