Reinstall the driver. It might think it's installed correctly. If the suite is an application outside of the driver, then reinstall the suite also.

try pressing f4 or f8 or f12. it varies on each pc depending on the bios setup.
goodluck

check if the wireless driver is present or installed on your laptop..

start>right click computer>manage>devices> check to see if there is a yellow exclamation mark beside your camera device.
start>all programs> windows update - make sure that the computer has been fully updated.
restart computer after updates. if camera still does not connect uninstall driver and download driver from website as previous version might be corrupt

Title: my laptop brand acer aspire 4750G is volume low problem

Ok, you can purchase a good quality Headphone or a woofer to improve your soun quality.
Otherwise you install Winamp with DFX, that also increase your sound quality as well as volume.

Have a look on the front edge of your laptop. I expect there is a switch there that can turn the wireless off and on.

Turning the switch on should show a message on the screen saying its been enabled.

Thanks

Heres how... Its normal to have 2(two) display adapters on Acer Aspire 4750G. To enable NVIDIA GeForce, install the Intel HD Family Chipset Driver First from the installation disk that is included on its package, or click here, or if link doesnt work find it here. Then install the NVIDIA GeForce Driver, also included in installation disk, or click here. That should fix it. Enjoy the 2GB NVIDIA GeForce GT 540M.

sure..you'll need to select or add that wireless configuration to your list
