Wish you could turn Nvidia Optimus on and off? The Lenovo Legion 5 15IMH05H lets you do just that

Lenovo Legion 5 15IMH05H Review: Excellent power delivery and good battery life
The Legion displays all games smoothly on its matte 15.6-inch display (120 Hz FHD, IPS). The integrated GPU is activated as a standard but can be deactivated with the click of a button. The battery life is very good as well.

The Lenovo Legion 5 15IMH05H is an upper mid-range 15.6-inch gaming notebook. The notebook will look familiar to users who know the Lenovo gaming series - although there are some differences to the predecessor Legion Y540-15IRH

Our test configuration is equipped with a Core-i5-10300H and a GeForce-RTX-2060. This hardware combination can display all current games smoothly on the Lenovo Legion 5 - usually at Full-HD resolution and high to maximum quality settings. The UHD Graphics 630, which is integrated into the processor, is activated and can be used thanks to Nvidia's graphics switching function Optimus. If necessary, users can deactivate the iGPU (in other words Optimus) directly in the BIOS or via Lenovo Vantage.

Lenovo has equipped the Legion with a Full-HD IPS display with 120 Hz. The panel offers stable viewing angles, a matte surface, acceptable response times, a good contrast ratio and decent colors. The maximum brightness and color space coverage are too low, however. We expect more from a $1250 notebook. 

Our test unit is equipped with an NVMe SSD with 512 GB of storage capacity. This can be expanded as the notebook provides space for either a 2.5-inch storage device or a second NVMe SSD (M.2-2280). Users will have to choose between one of the two, however, as the 2.5-inch caddy would have to be removed to install the second SSD.     

The Legion does not include a Thunderbolt 3 port, which would have enabled users to connect an external GPU, for example. Instead, the Legion 5 offers one single Type C USB 3.2 Gen 1 port, which at least supports the DisplayPort via USB C function.      

Find out more about the device and its benchmark results in our review of the Lenovo Legion 5 15IMH05H (8160043GE).
