Why is my power light now red instead of blue

[struggling]

Hello,
My powr light on my Acer Windows seven is usually blue....suddenly it is red...Why?

hmm it appears you have some sort of hardware problem. Your Acer may need to be serviced.

The LED maybe hooked up backwards (as LEDs tend to look red when reversed before burning out) or failing; or it could be as nhasian said that there is a fault that the led is warning you about.

If you have the manual you can check and see if this is an indicator light.
