I really don't think that the battery charge is a problem, because PowerChute says that it is fully charged at 100%. However, something may be quirky with the installation anyway, because I just had to reboot for other reasons, and reaching desktop again, It displayed a rather cryptic message about it loading what appeared to be the APC driver again. I thought that I had a screenshot of it, but I failed to pasted it into paint before rebooting once more, after Windows did say that it had installed the driver and that a reboot was required. Since the driver had already been installed, I don't understand why it had to do that again, but at least Powerchute is now running again also. I guess that I will just have to wait and see if a problem persists.
