How to set the thickness of the flashing cursor on Lenovo notebooks under Windows Vista is as follows:

1. Click "Start" --> "Control Panel" (Control Panel home page), and click under Ease of Access "Optimize video display".

2. In the "Make the computer easier to display" window, select "Set the thickness of the flashing cursor". The larger the selected number, the thicker the cursor will be (this value ranges from 1 to 20 integer values). Then click the "Save" button.

3. After the settings are completed, open any text editing window, and the blinking cursor will change the thickness.
