I am in Switzerland and have a UK Dell laptop. It has been working fine with a EU plug adaptor on the UK plug. Now when I try to turn on the power on my laptop, it will not fire up. I get a red light come one showing the battery indicator. What does this red light mean? If I hold down the power on button for 3 - 5 seconds, the red light still comes on together with a blue light on the power button but still nothing comes up on the screen. What does the lights mean? I do not know what is going on here. Please help! Thanks very much.
