LCD backlight dim
Re: LCD backlight dim
Dim backlight -> Usually indicates an old CCFL display. The bulb is probably at the end of its lifetime.
However -> LED indicators not working may indicate that the inverter is damaged. The inverter also regulates the backlight, so there might be a connection.

Re: LCD backlight dim
Are you running Windows? Did you try changing the Power Options in Windows?
Is this only while on Battery power or when the laptop is plugged in / charging?
