This weekend I unplugged the main power while it sat all day. The voltage seemed fine and the battery didn't go down much at all. I know it's still a flakey battery by not being able to recover from a high load so I'm going to get a Optima red top next week.Originally Posted by nkotch
So know I wanted to know how much current the PC was drawing when off, so I went out and bought a new DMM. I measured my current draw by putting the leads inline between the power wires.
Off it was 330mA!
I turned the PC on and then let it go off again and it went down to 190mA. There is something about cutting power and then connecting it again that makes it draw the higher 330mA. Once the PC cycles once it returns to the normal 190mA which is about average I think.
S3 standby/suspend was 280mA. Also average I believe. So I guess it's just my battery being old, going out and not being able to handle this small load for long.
BTW, my PC was drawing about 4.5amps when running which is less than I thought it would be. I know the Opus 150 has a 15A fuse which is about it's limit before something will melt. During start up I saw around 6.3 amps at it's highest.
