当笔记本出现双显卡无法切换的情况时，一般是由于显卡驱动没有正确安装导致，可以尝试通过以下方法排除：
首先确认是否安装的是XP操作系统，若为XP系统则无法识别到独立显卡，建议更换Win7以上操作系统。
2显卡驱动一定要通过三星官网下载，不能通过第三方途径下载。
3先安装核心显卡驱动，再安装独立显卡驱动。
4如果确认显卡驱动下载途径和安装方法没有问题，建议将操作系统重新安装后观察（重装系统前请先备份重要资料）。
5若以上操作均无效，建议联系售后服务中心。

亲身测试：复制其中一位老哥的语言，在三星官网下载三星升级管家，安装后输入电脑型号Q470，不用执着自己的笔记本型号，与之相近就行，我的是ZT03，但是这个型号下的软件win10不能安装，我选的是JS08的好像是， 然后操作系统选win8，下载的settings的版本是20072的。完美安装完美驱动 -----注意：重启电脑后，你会发现键盘灯背光亮了，软件也可以用了！！！！
可以按照如下步骤进行尝试：
1开机在出现三星Logo时按F2进入BIOS设置，选择恢复出厂设置后，将笔记本BIOS重置。
2查看设备管理器内“Bluetooth无线电收发器”内声卡前是否有叹号或被禁用。
3如已经自行安装了Windows 操作系统，安装了公版或不兼容的驱动程序，可先卸载不兼容驱动程序，通过以下链接到三星官网下载SWUpdate软件搜索您的机型更新对应系统的Easy Settings软件及网卡驱动。
4备份好资料重新还原操作系统或重新安装操作系统。
5如若还不能解决故障，电脑的硬件也许发生了故障，请与当地售后服务中心联系。
"笔记本的驱动是特制的，所以可以使用快捷键来调节屏幕亮度和进行显卡热切换
如果你安装的驱动不对，就无法支持这些特色功能
你可以去官网安装笔记本的型号下载相应的驱动进行安装，
或者下载一个腾讯电脑管家，使用硬件检测功能来安装驱动，
它可以检测出硬件的详细型号，为您匹配相应的稳定驱动"
