Question about Acer Aspire 4520-5582 Notebook
I have an Acer Aspire 4520, AND the os is WIN XP. when I check the device manager there is an unknown device on the list. Under properties for this device it gives the following as the device instance id (ACPI\WEC1023\4&36128FA&0) Does anyone know what this is ?Does it have something to do with having no sound?
Update the unknown device driver using CIR or card reader driver or reinstall the card reader and CIR drivers.
or Try flash your bios with version 3632 bios for XP(recommended)...

Unknown devices usually have to do with a utility driver. Download all utility drivers for your machine at Acer's support site and this should take care of it. When you hit the right driver it will find and tell you exactly what the unknown device is.
