Notice on deleting data from your solid-state drive

Some of the data stored on the solid-state drive might be sensitive. Handing your computer over to
someone else without deleting the installed software, such as operating systems and application software,
might even violate license agreements. Be sure to delete data stored on the solid-state drive before you
dispose of, sell, or hand over your computer.
You can use the following methods to delete data from the solid-state drive:
• Move the data to the Recycle Bin, and then empty the Recycle Bin.
• Delete the data.
• Format your solid-state drive, using the software for initializing it.
• Use the recovery program provided by Lenovo to bring the 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 operating
system. 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 the solid-state drives for unexpected purposes.
To prevent leakage of data, it is important that you delete all the data from the solid-state drive when
you dispose of, sell, or hand over your computer. You can destroy the data physically by smashing the
solid-state 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.
If an Encryption solid-state drive is supported and installed in your computer, you can logically dispose of
all the data on the drive in a short time by erasing the cryptographic key. The data encrypted with the old
key is not physically erased but remains on the drive; however, it cannot be decrypted without the old key.
This feature is also available with the Drive Erase Utility for Resetting the Cryptographic Key and Erasing the
Solid State Drive tool.

Using firewalls

If your system is preinstalled with a firewall program, it protects against computer Internet security threats,
unauthorized accesses, intrusions, and Internet attacks. It also protects your privacy.
For more information about how to use the firewall program, refer to the help information system that
comes with the program.
