重启称重软件后鼠标乱动、链接不上串口怎么办

作者:衡安称重软件公司来源:衡安称重软件发布于:2014年01月3日

　　
有时候电脑重新启动称重软件后发现不能打开串口或发现鼠标乱跑，不能控制。这是因为WIN2K或WINXP在启动时检测了外部设备导致的。
　　注意，仪表一般是插上电就已经工作了，仪表表面的开关只能关闭显示屏，不能关闭电源。有些仪表背面有电源开关，总之是要彻底的关闭仪表。
　　如果出现了这个故障，先拔掉串口线，再重新启动电脑。启动后再插上串口线。串口线就是仪表连接电脑的线。
　　解决办法：
　　1、开机时先开电脑，等电脑启动完成了在插上仪表电源。

　　2、先关掉仪表电源，这样屏幕上的鼠标就不会乱跳了。然后在我的电脑上点击鼠标右键，在菜单中找到《管理》菜单项，选中它，出现“计算机管理”窗口，在左边项目中找到“设备管理”项目，单击选中它，在右边项目中找到“鼠标和其他指针设备”，展开它，在“Microsoft Serial BallPoint”项目上点击右键，在菜单中选中《停用》命令，此时可能会弹出警告对话框，不用理会，点《确定》即可。这样“Microsoft Serial BallPoint”项目就会变成下图所示，以后重启电脑，开仪表等，都不会再出现鼠标乱跳现像了。
