【已解决】25周年的两个问题

henrymyf

刚刚收了一台成色充新的T25，港行，但随即发现两个问题：
第一、指纹驱动一直有问题， 明明刚刚安好驱动，在设备管理器里面没有报错，但一运行登录选项中的指纹设置，就会报错，然后设备管理器里面就会出现叹号。按网上的一些教程，仍然不行。

第二、是开机按F1后无法进入BIOS， 经常卡在黑屏状态，只能长按电源键强制关机，然后再开机。但我只有一次幸运进去过BIOS，其余时间都是卡在黑屏状态。
收到机器后，我并不记得有升级过系统。希望只是软件问题。如果有哪位网友有类似的经验，请告知。多谢！

[Update: this solution worked only temporarily - see below] I solved this, but the solution wasn't obvious, so I will post it here. It was a driver issue, which occurred during the normal course of applying automatic updates from Windows and/or Lenovo. The correct driver update was installed, but something went wrong in the process. Details are beyond me, but here's the fix:



Go to T470 Driver Support Link and download the latest fingerprint reader driver (currently version 5.2.3524.26). This is an executable file.



Run the executable, which extracts the driver files. Remember the folder location. You can go ahead and complete the driver installation process through the executable, but it won't fix the problem (in my case).



In device manager, right click the Synaptics WBDI(SGX enabled) driver, which in my case was showing Error Code 10, and select update driver.



In the update driver menu, select "Browse my computer for driver software", then "Let me pick from a list of available drivers on my computer", then "Have Disk", then "Browse".



Navigate to the folder noted above, which in my case was C:\DRIVERS\WIN\FPR\WBF_Drivers, and select the file "synaWudfBioUsbLenovoMiSSGXProd.inf".



Complete the install process, then restart the computer. The driver error goes away, and the fingerprint reader now works.



Any other method of installing the driver, including running the driver update program from Lenovo, results in a driver error. If I were to guess, I'd say a generic version of the driver is getting installed with the latest updates, and not the customized version from Lenovo. The above manual process installs the correct driver. That's just a guess.

第二个问题检查升级BIOS版本看看。

已经解决这两个问题了，虚惊一场。大概分两步：

1、开机先按回车interrupt normal startup，然后按F12进入启动清单，再按Tab切换到APP，然后选“Setup”，就可以进去BIOS了；

2、在Security那页，指纹里面把Predesktop设置改为Disabled，然后按F10重启，之后再怎么重启都可以任意按F1正常进入BIOS了。

这时如果再正常启动回Windows，进入设备管理器，就会惊喜地发现驱动好了！再进入登录选项，就可以正常设置指纹了！

没想到这个Predesktop的设置会联动两个级别的问题。不过也好，这使得我在极短时间内，就对T25有了较深刻的理解。相信未来的日子，我们也能相处愉快。

HOPE老大，我会把这台电脑用好的。
