You can set the screen brightness to a comfortable level for different environments. You can also set the display delay time to automatically turn off the display when you are away from the computer.

User Guide
Problem: Ripple on screen Troubleshooting and problem resolution: 1. Check for devices located less than one meter from the computer such as refrigerators, electric fans, electric dryers, UPSs, regulators, fluorescent lamps or other computers that may be generating magnetic interference. Move any interfering devices away from the computer. If the problem persists, consult with Lenovo Service.
4. 2 Troubleshooting Audio Problems
Problem: No sound from integrated speakers. [. . . ] This may account for the apparent hard disk capacity deficit. Further Technical Explanation: The nominal capacity of the hard disk is expressed in the decimal system, 1000 bytes. But the actual hard disk capacity is expressed in the binary system as 1024 bytes (For example, the nominal capacity 1G is 1000M, while the actual capacity 1G is 1024M). The capacity of the hard disk shown in Windows can be calculated according to the calculations in the following example: The nominal capacity of the hard disk is 40G, while its actual capacity should be: 40 x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 37G.
