Hey there - I have a Sony Vaio FXA 47 notebook with an AMD Athlon 4 1 GHz running Windows XP. Some time ago the computer just started shutting down after 5 minutes on battery. The AC/battery status utility icon stopped showing up in the task bar on the main screen and could only be accessed through the control panel. I haven't been able to use battery power since, even though they were fully charged. Computer would run for a short time on battery and then shut down.
Just the other day it all came back! Everything worked find for a few days. I was able to run the batteries (I have 2 in this computer) right down over a few hours and then recharge them, until today when this dog-gone thing stopped recognizing the batteries. So, batteries are just fine. The icon still shows up in the task bar, but when on batter power the icon still shows AC power and indicates batteries are not installed!!
Someone mentioned something about a "power monitor" or some type of utility that can be downloaded that overrides the built in one (in the BIOS?) to get around this. Anyone know where I can find this or have any other suggestions (other than giving this thing a swift kick)? Thanks much for your thoughts.
what windows version? the "battery monitor" like other devices needs drivers and if the ones for the battery have become corrupted then that's your problem, simply go into device manager (winxp/2000), go to batteries and delete the 3 entries: Microsoft ac adapter Microsoft acpi-compliant control method battery Microsoft acpi-compliant control method battery
then reboot and that should fix it if it is corrupted drivers.
