application performance.
CD or DVD drive speed is the variable read rate. Actual speeds vary and are often less than the
possible maximum.
When referring to processor storage, real and virtual storage, or channel volume, KB stands for 1
024 bytes,MB stands for 1 048 576 bytes, and GB stands for 1 073 741 824 bytes.
When referring to hard disk drive capacity or communications volume, MB stands for 1 000 000
bytes, and GB stands for 1 000 000 000 bytes. Total user-accessible capacity can vary depending
on operating environments.
Maximum internal hard disk drive capacities assume the replacement of any standard hard disk
drives and population of all hard-disk-drive bays with the largest currently supported drives that are
available from Lenovo.
Maximum memory might require replacement of the standard memory with an optional DIMM.
Each solid-state memory cell has an intrinsic, finite number of write cycles that the cell can
incur.Therefore, a solid-state device has a maximum number of write cycles that it can be
subjected to, expressed as total bytes written (TBW). A device that has exceeded this limit might
fail to respond to system-generated commands or might be incapable of being written to. Lenovo is
not responsible for replacement of a device that has exceeded its maximum guaranteed number of
program/erase cycles, as documented in the Official Published Specifications for the device.
Lenovo makes no representations or warranties with respect to non-Lenovo products. Support (if
any) for the non-Lenovo products is provided by the third party, not Lenovo.
Some software might differ from its retail version (if available) and might not include user manuals
or all program functionality.
7.3.3. Particulate contamination
ATTENTION: Airborne particulates (including metal flakes or particles) and reactive gases acting
alone or in combination with other environmental factors such as humidity or temperature might
pose a risk to the device that is described in this document.
Risks that are posed by the presence of excessive particulate levels or concentrations of harmful
gases include damage that might cause the device to malfunction or cease functioning altogether.
This specification sets forth limits for particulates and gases that are intended to avoid such
damage. The limits must not be viewed or used as definitive limits, because numerous other
factors, such as temperature or moisture content of the air, can influence the impact of particulates
or environmental corrosives and gaseous contaminant transfer. In the absence of specific limits that
are set forth in this document, you must implement practices that maintain particulate and gas
levels that are consistent with the protection of human health and safety. If Lenovo determines that
the levels of particulates or gases in your environment have caused damage to the device, Lenovo
may condition provision of repair or replacement of devices or parts on implementation of
appropriate remedial measures to mitigate such environmental contamination. Implementation of
such remedial measures is a customer responsibility.
