Used for about six months. After switching the PC to HP, the charging indicator light came on, so I changed the charger to an Anker 67W. It worked on the Surface (touch screen type). HP (charging indicator lights up, but can charge) → Does not blink with the official charging equipment. The HP could charge without the charging indicator lighting up when using the Anker 67W charger. Please check the product in the photos. Price negotiations are not possible. I cannot create a reserved listing. Thank you for your understanding. Cancellations and returns are not accepted after purchase. Please refrain from purchasing if you are sensitive to used items.
