How do I properly clean my laptop display??
There are fingerprints on it.
for my computer LCD screen I bought staple's screen cleaning fluid, and they say it works with notebook screens as well, all you need is to buy a cloth with it and they also sell premoistened cloths
The pre-moistened wipes can be VERY bad for your LCD display as they have a tendency to dry out and can scratch the display. I would stick with a soft cloth like the ones that you use on a camera or a shammy (sic?) like the ones you use on your car. And make sure that you use a liquid cleaner that is safe for LCD monitors and such.
If your noise occures when you have system sound "MUTED" it may be an outdated driver. I had the sam issue. Go to http://support.dell.com/support/downloads/index.aspx?c=us&l=en&s=gen
Enter your computer information and find the Audio Drivers for your terminal. Download and install the latest driver and reboot. Your problem should be fixed.
