What size is the power socket lead is it 5.5 outer and 2.5 inner thanks for your help

From my repair experience, 5.5 OD and 2.5 ID is commonly use on the power supply adapter since 2.5mm is made to handle higher current than the 2.1mm (2.1mm is usually for 2A or less).
Center is also positive.

Start --> Settings --> Control Panel.
Sounds and Audio Devices.

There is a volume slider here, and should be an option to put an icon in the system tray where you can click to adjust the volume anytime. Make sure you are not muted.
