* As pointed by in the comments below, the 16GB cache drive is not built-in to the motherboard, but exists as a hidden M.2 slot behind the inbuilt battery.Thanks to ‘ Pedro Smith‘ for pointing this out. The screws on the bottom of the laptop do not come off.MyDigitalSSD’s cache management solution only identifies their own drives!

Because if you remove, the 16 GB drive would not be used as a cache drive anymore. Do not go that route, if you are installing a new drive in the 3rd slot as I did.

The instructions that come with that MyDigitalSSD drive suggest removing of the Lenovo cache management tool and replacing it with their own tool.

from this SSD drive and TRIM support is automatically enabled. Shortcut keys are ‘Enter’ to enter BIOS, F12 to show boot order menu. Remember to set the Boot Mode to ‘Legacy’ or ‘Dual’ in boot options, to boot up fedora. The free slot is next to the WWAN card as shown in this picture. But any other operating system can be installed on it & hence, it can be used as a third drive! I installed the MyDigitalSSD 42mm SSD drive in the free M.2 NGFF slot and loaded Fedora on that partition.

In default configuration, it is used as a cache drive for the pre-installed Win 8.

Apart from these two slots, a 16 GB SSD cache drive also exists in a hidden slot behind the inbuilt battery*. The other slot accept M.2 NGFF format drives, a new standard to replace the mSATA standard. First one is the usual standard 2.5′ SATA 3 slot. I ordered mine with 500GB mechanical drive and a 16 GB cache SSD. I use the soft tap to do left/right clicks, to avoid the mistakes.Īnyway, the ‘S’ model comes with a unique HDD configuration. No physical buttons, the whole trackpad is a button! This leads to quite a few false clicks, as the pointer moves while pressing the clickpad/trackpad. Like the laptop overall except for the trackpad.
