It you have issues with the charge level, just shut down the program and re-open it. It should revert to the corect level.
I will allow that CHC may be providing false readings. I already considered that and have made observations with and without CHC running. Here are some undeniable facts:
1) After a few months of operation with a brand new battery (no matter whether during that time the battery is deeply discharged or slightly discharged, frequently or seldom) the notebook enters a state where it will continue to charge the battery after the control panel power meter says the battery is fully charged, no matter whether CHC is running or not. This is evidenced by the battery charging light being illuminated, by the control panel power meter indicating that the battery is both 100% charged and charging, and by CHC which indicates 100% charge and a trickle charge (usually 0.165 watt);
2) After the notebook enters the state of continuous battery charging it is only a matter of days before the notebook fails to fully charge the battery after a deep discharge, whether CHC is running or not. In fact, both the control panel power meter and CHC show the same charge percent while in this state, and this number ranges from 0% to 99%. Once in this state, after each deep discharge the highest attainable charge is dimiinished. Increasingly shorter durations of operation running on battery are observed.
It is the last sentence of item 2 that is the basis for a warranty claim. Of course, anyone who does not see this behavior with their z71v cannot use this as a basis for a warranty claim. The message board apologist for Asus says there are thousands of such individuals who have not experienced battery charging problems with the z71v. Perhaps there are, but I am not one of them. In my situation and I gather many others have the same experience, the z71v is unreliable as a mobile device since you can never count on it being able to run on battery for an acceptable time on any given day.
If the CHC readouts I observed yesterday are accurate, viz., that the battery is being overcharged at a sustained high charging rate, then this notebook poses a hazardous condition that may result in personal injury. That, of course, is speculation. Items 1 and 2 above are not.
