Lenovo T54H 用户手册

You can tilt the screen backward and forward as shown below.

This section gives 
advice on how you can 

work comfortably and reduce 
fatigue.

Take regular breaks. Vary your posture, stand up and stretch occasionally as 
prolonged use of computer workstations can be tiring.

You should sit back in your chair and use the backrest.

Adjust the seat height so that your forearms are approximately horizontal and 
your wrists are straight when using the keyboard. Your upper arms should be 
relaxed with your elbows near your body.

Use a light touch on the keyboard, keeping your hands and fingers relaxed. 
Allow a space in front of the keyboard to rest your wrists when not typing. 
Consider using a wristpad.
