• The reader often fails to enroll or authenticate your fingerprint.
If your finger has any of the following conditions, you might not be able to register or authenticate it:
• Your finger is wrinkled.
• Your finger is rough, dry, or injured.
• Your finger is stained with dirt, mud, or oil.
• The surface of your finger is different from when you enrolled your fingerprint.
• Your finger is wet.
• A finger is used that has not been enrolled.
To improve the situation, try the following:
• Clean or wipe your hands to remove any excess dirt or moisture from the fingers.
• Enroll and use a different finger for authentication.
• If your hands are dry, apply lotion to them.
For more information on how to use the fingerprint reader, refer to the help system of the Lenovo Fingerprint

Notice on deleting data from your hard disk drive, hybrid drive, or
solid-state drive
Some of the data stored on the hard disk drive, hybrid drive, or solid-state drive might be sensitive. Handing
your computer over to someone else without deleting the loaded software, such as operating systems and
application software, might even violate license agreements. Be sure to delete data stored on the hard disk
drive, hybrid drive, or solid-state drive before you dispose of, sell, or hand over your computer.
You can use the following methods to delete data from the hard disk drive, hybrid drive, or solid-state drive:
• Move the data to the Recycle Bin, and then empty the Recycle Bin.
• Delete the data.
• Format your hard disk drive, hybrid drive, or solid-state drive, using the software for initializing it.
• Use the recovery program provided by Lenovo to bring the hard disk drive, hybrid drive, or solid-state
drive back to the factory default settings.
These operations, however, only change the file location of the data; they do not delete the data itself. In
other words, the data retrieval processing is disabled under an operating system such as Windows. The
data is still there, even though it seems to be lost. Thus, it is sometimes possible to read the data by use of
special software for data recovery. There is a risk that people of bad faith might read and misuse the critical
data on hard disk drives, hybrid drives, or solid-state drives for unexpected purposes.
To prevent leakage of data, it is important that you delete all the data from the hard disk drive or hybrid drive
when you dispose of, sell, or hand over your computer. You can destroy the data physically by smashing the
hard disk drive or hybrid drive with a hammer, or magnetically by means of strong magnetic power, thus
making the data unreadable. But it is recommended that you use the software (payware) or service (pay
service) developed for that purpose. The process might take several hours.
For disposing of data on the solid-state drive, Lenovo provides the Drive Erase Utility for Resetting the
Cryptographic Key and Erasing the Solid State Drive tool. For disposing of data on the hard disk drive, Lenovo
provides the Secure Data Disposal
™ tool. Go to http://www.lenovo.com/support to download these tools.
