My Computer LED light comes on but wont boot?
Last night it was working fine. I shut it down before bed and this morning the green LED light was on. I Turned on the screen but there was no picture and the button would just blink. I tried to shut the computer down but the light wouldnt go off. I unplugged it and tried other outlets but it didnt help. The fans dont spin and there is no normal computer sounds when it is plugged in. The LED light just stays on. Has anyone had this problem?
How do I hook up this LED light to a battery?
Here is the light – http://www.flickr.com/photos/31355277@N03/ I would prefer the battery be rechargeable and not too large. I would like for the battery to power this thing for a while, this isn’t temporary or to test the light. I’m not sure how many volts this little device is, but it is a blue LED light(or rather 4 little LED lights or "bulbs"), and you see the 2 wires. Thank you!

How long would a Car battery power a 0.040A LED light?
I have an LED light that consumes 0.040A of power, and wanted to know, in a worst case scenario, how long a car battery could power that.
Also, if I doubled it and it consumed 0.080A of power, would it be safe to say that I will have half the time, or is it somehow exponential?
Please explain in laymen terms.
