Hello all,

I have a new X240, and the fingerprint logon no longer works after the computer resumes from standby or from a lockscreen (screen saver). I have checked other solutions here and in other sites, namely:

1. unchecking the power option of the fp reader in device manager,
2. switching off the 30-day standby in Lenovo Settings

Neither of those solutions have worked. I have the latest BIOS and FP driver versions. I made sure the the FP was enabled in BIOS, and I even switched the settings to allow internal FP reader only. Still, the FP will only work when I first power on the laptop, but not after resuming from stand-by. I have checked in Device Manager after manually entering the password, and it says that the FP is working properly.

I am at a loss, and I want to exhaust every possibility before I call tech support. Any suggestions would be appreciated.

Fixed.

I normally use System Update to check for newer versions of Lenovo software. SU didn't catch that there was a new version of FP reader. Just to be sure, I doublechecked on Lenovo's website, and lo and behold, there was a newer version of the FP reader. I had to download it and manually uninstall the previous version. It's fine now. However, I don't understand why Lenovo does this - why does SU not catch updates? It's not the first time that this happens, by the way, nor is it limited to this laptop (I own or have owned a T60, X61, X200, X201, X230, T410, and now the X240).

In any event, the FP is working properly now. I hope this helps someone else.
