surface pro11充电时候漏电

晚上好，朱星燃，

请不必担心，Surface 电脑在充电时轻微漏电是各型号普遍存在的正常现象，您的设备并未故障。我自己的两台 Surface 电脑连接了电源线时也会有明显的漏电。

Microsoft 在 Touch current and Surface devices 文档中指出：

Touch current, or “tingle current,” may be detected by some device users when a minute, non-hazardous amount of residual electrical current passes through the user when touching a device. The sensation caused by touch current can range from a sensation of vibration, to a slight tingle or mild pinpricks. (触摸电流，也称 “刺痛电流”，是指在触碰设备时，有微弱且无害的残留电流流过身体，一些用户可能会察觉到这种电流。触摸电流引起的感觉范围从震动感到轻微刺痛乃至针刺感。)

Touch current may be detected when a device is plugged into wall (mains) power. Normally, electricity runs from the wall outlet, through the device, and back to the wall outlet in a short, closed-loop system. Touch current may be noticed if a tiny fraction of the electrical current passes through a user rather than returning to the wall outlet. Good device design and electrical safety hazard tests ensure that any touch current passing through a person is insignificant and non-hazardous. (当设备插入墙壁上的 (主) 电源时，可能会出现触摸电流。一般情况下，电流从墙壁插座流经设备，然后通过短闭环返回墙壁插座。如果极小一部分电流流过了用户而没有返回墙壁插座，则可能出现触摸电流。良好的设备设计和电气安全隐患测试可确保流经人体的任何触摸电流都是微弱且无害的。)

Microsoft’s internal standards for touch current, which are stricter than the applicable regulatory standards, are designed to minimize the perception for touch current. (Microsoft 内部采用的触摸电流标准比相关监管标准更为严格，旨在最大限度降低用户对触摸电流的感知。)

总之，即便没有安全风险，日常也建议避免用湿手触碰电脑、尽量不用胳膊等对电流敏感的身体部位接触电脑，以免被突然的刺痛感吓到。

谢谢！😀

顺颂 时祺
