To mute the notebook
Your notebook provides several ways to mute its speakers without changing the volume
setting. This can be handy when you want to block all speaker output regardless of what
the notebook is doing.
• Press Fn+Backspace to toggle the mute function.
• Click the speaker icon in the taskbar, then click Mute.
• If your notebook includes a mute button (located on the notebook’s right side), press
the button to toggle the mute function. The mute indicator lights when the speakers
are muted.
To optimize video performance
Depending on how you use your notebook, you may want to increase the amount of
memory it can access for video processing.
To increase video memory
1. Click Start, Control Panels, Appearance and Themes, Display, then click Advanced
on the Settings tab.
2. On the S3Info Plus tab, set the video memory size. HP recommends 16 MB for most
computer uses, and 32 MB if you run programs such as video games that make heavy
use of the notebook’s video capabilities.
3. Restart the notebook for the changes to take effect.
