2 Memory-upgrade slot
You can increase the amount of memory in your computer by installing a memory module in the
memory-upgrade slot. Memory modules are available as options from Lenovo.
3 Wireless LAN card slot
Your computer includes a wireless local area network (LAN) card for you to establish wireless LAN
connections.
4 Hard disk drive or solid-state drive
Depending on models, your computer might have a large-capacity, customer-upgradable hard disk drive
that can meet a variety of storage demands.
Some models are equipped with a solid-state drive for data storage, making your computer lighter, smaller,
and faster.
Note: The hidden service partition is the reason why there is less free space than expected on your hard
disk drive or solid-state drive. This reduction is more noticeable on the solid-state drive because of its
smaller capacity.
Status indicators
The status indicators show the current status of your computer.
System-status indicators
The illuminated dot in the ThinkPad logo on the outer lid of your computer and on the palm rest works
as a system-status indicator.
