1 M.2 solid-state drive slot
For some models, an M.2 solid-state drive might be installed for data storage.
2 Emergency reset hole
If the computer does not respond, remove the ac power adapter and reset the computer by inserting a
straightened paper clip into the emergency reset hole to turn off the computer.
3
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.
4 Integrated battery
Use your computer with the battery power whenever ac power is unavailable.
5 Hard disk drive or solid-state drive
Depending on the model, 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.
6 Wireless LAN card slot
Your computer might have a wireless LAN card for you to establish wireless LAN connections.
