Well, the battery has been replaced this afternoon. It took between 2 and 2 1/2 hours. The system seems to be functioning ok so far, but I haven't yet booted up in windows-7, and I haven't yet tried a "dnf upgrade". Before I took the system apart, I checked the CMOS clock and the voltages reported by the motherboard in the UEFI BIOS display: * CPU voltage varied, but was 0.98 +/- less than 0.01 volts. * "3.3V Voltage" was 3.392 volts. * "5V Voltage" was 5.040 volts. * "12V Voltage" was 12.096 volts. The CMOS clock seemed slightly slow compared to my "atomic" clock, but by less than 1 second. I gather none of the voltages displayed was the battery's voltage; I could not find a battery state indication in any of the BIOS displays. After the battery change was done, I checked the old battery with a battery tester. It was well in the "green range". I agree with the criticisms about ASUS making the battery so difficult to access on this motherboard. I also found the USB 3.0 connector to be a problem. The pins were too crowded, too close to the socket wall, and too easily bent. I had to straighten out two of them, and it was difficult. Getting the plug into the socket took very careful and delicate alignment. I hope to try the smartctl long test on the hard drive tomorrow. thanks, Bill. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
