吃个饭， 一会开更。

先上效果图，

t驱动支持了？

占座，学习

快更！

开更，楼主希望能帮助到某些同学，毕竟第一次发教程，突然感觉自己萌萌哒。
首先，在某宝可以买到两种三键触摸板，一种触摸板的材质是类似塑料的感觉，另一种是玻璃纤维的感觉，楼主买到的是塑料的。 玻璃纤维版的直接换上装上2015版本的驱动即可用了，但塑料版的还要看到下面楼主的独家内容哦。
1. 拆。
如图， 拆下D面， 扭开电池的螺丝拿下电池， 扭下如图里五个螺丝，和两个插口，
楼主的因为已经换完了，新三键触摸板只有四个螺丝，所以像图上一样废了一个螺丝。
然后是最中间的触摸板的排线（往下看）和右侧两个螺丝之间的NFC的接线。楼主因为当时过于用力，将NFC的接线完全扯了下来， 不过因为平时根本不用这个功能，所以对楼主也无所谓了。 不过真的很难拔掉。
2. 换。
先说一下这个触摸板排线的拆装。 没什么难的，楼主要强调的是，小心一点弄~~
如下图，将楼主标注的黑色开关向屏幕外侧拉起九十度。排线即可拉出。 楼主觉得这个排线比较脆弱，操作的时候小心一点就好。
这些都撤掉以后就可以从键盘那一面拿下。
换上三键触摸板以后，装上螺丝后，装这个排线。 这里真的是需要付出耐心，小心一点将排线插进去，然后将黑色开关放下就扣上了。 没有弄坏NFC排线的同学&还用NFC的同学的话，可以将NFC接线插回去，楼主的已经扯飞了。
这样就换好了， 下面是驱动部分。
3. 驱动
如楼主所说， 玻璃纤维的触摸板和塑料的 楼主都买来了，试一试手感以后楼主决定装的是塑料的，因为觉得玻璃纤维的过于滑了，但是手感这个事见仁见智了就，同学们自己决定。
玻璃纤维的触摸板 装上2015驱动可以直接驱动完美，楼主这里要写的是塑料版本。
塑料版本的同学装好了2015版本的驱动以后重启，会发现触摸板好用，三键不能用，而且驱动的面板里没有任何改变，不要急。往下看。
楼主把2015版的机器的注册表的如下路径下的内容copy给了2014版本，就OK了呢
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SynTP\Parameters
而为了方便同学们，楼主将reg脚本放在下面，同学们直接弄到txt里保存成 .reg格式 后 直接双击运行就好。 大功告成！！！ 。 2014版本的同学们也可以享受三键了。

我的任务完成了，谢谢同学们。

楼主现在用的三键是背面铁件光滑的那种？

借楼求t450基友发注册表相关键值@校园单间出租

对了请问楼主，三键触摸板真的分玻璃和塑料版本，而不像JS说的只有塑料吗？

T440p已成功，使用最新驱动！

LZ能帮助我不？我的型号是E540。不装驱动可以用三键，装完驱动三键失灵。用了注册表依然无效。

请问楼主，你x1carbon撕膜用的是什么工具啊？我用牙签、指甲和一字螺丝刀都没有撬开屏幕的四角！
我也是看着那个磨砂的膜真实万分不爽啊！
楼主撕膜后有什么问题出现吗？

建议吧主加精啊，楼主用心了，原来@我没有蓝

重要参考，准备给x240换个三键触摸板。马克

感觉T460s那种毛玻璃的触摸板好很多
