System: Lenovo N500, Vista Home Premium
Q: This is an annoyance more than a problem, but every time the battery on my laptop starts to run low and I plug in the charger whilst the machine is switched on it makes a really loud beep. Since I often use the machine in the library I’d like to stop this but I can find any way to do it. Can you offer any hints?
A: This is a feature of Lenovo laptops, it’s the machine letting you know that it’s properly connected and beginning to charge. However, we agree that it is annoyingly loud. The beep is generated by the system speaker rather than the ones used to play audio and that’s a clue to fixing it. Go to Control Panel and select Sound, then in the Playback tab select the sound device (Conexant high definition) and click the Properties button. Select the Levels tab and you’ll see some volume bars, mute the one labelled PC Speaker and then reboot the machine. This should turn off the system beep without affecting playback of media files.
You can adjust the individual levels for different audio devices from Control Panel
