gThe A side of Lenovo Savior R9000P first reminds us of the "Y" character in the Lenovo Savior R9000P trademark. Users can use the Fn L shortcut key to unfold the power switch, and this light is in standby mode. When it is exposed, it will inhale and flicker, and the body curves on both sides of the A side make the entire A side more concise and layered. At the same time, the paint of the R9000P is very well done, with a delicate touch and is not easy to detect fingerprints. Five-star praise.
