My Dell Inspiron 15 i5548-1670SLV Signature Edition has Keyboard Backlight issue. Backlight is not glowing now. Keyboard is working as expected.
BTW, recently there was a power issue in my laptop and my battery is dead. Laptop is working only on AC power now. Checked the keyboard and both the wires from the keyboard are intact and does not have any problem.
All keys are working, and Caps Lock light is glowing when it is on. Just that the backlight is not glowing. Any suggestions on why its not working ?
