My computer was originally Windows8.1 system, re-installed system, changed to WIN7 64-bit system.
Open Control Panel--Find mouse properties, such as:
650) this.width=650; "src="/e/u261/themes/default/images/spacer.gif "style=" Background:url ("/e/u261/lang/zh-cn/ Images/localimage.png ") no-repeat center;border:1px solid #ddd;" alt= "Spacer.gif"/>650 "this.width=650;" src= "http ://s3.51cto.com/wyfs02/m01/7d/19/wkiom1bf4y7wp6w3aadyqhbvmtg879.png "title=" IXW) S ') (93}@l%{~n]5q8km.png "alt=" Wkiom1bf4y7wp6w3aadyqhbvmtg879.png "/>
The key is that after I re-install the system is no ThinkPad item, this article is about how to download the Touchpad driver, how to find the ThinkPad option.
I downloaded the latest trackpad driver on the official website, very disappointed, the installation is unsuccessful, prompt:
Synaptics device not found; 650) this.width=650; "Src=" http://s2.51cto.com/wyfs02/M02/7D/18/ Wkiol1bf5flcahtoaaaxuzksw9i719.png "title=" K6me (t9z~yif5}_0afcci2k.png "alt=" Wkiol1bf5flcahtoaaaxuzksw9i719.png " />
finally downloaded not the latest version of the driver, the installation has succeeded!!!
