I booted the 1.5 on AC (without the battery). Entered 'see-bstate' at the ok prompt - saw string of '0 3' repeating. Inserted bum battery. The Battery_LED on the 1.5 soon changed to yellow. Took the battery out of the 1.5 and put it into the "testing" XO-1. Battery_LED still yellow when AC power plugged in. Eventually, Battery_LED turned green. I'm concluding this problem battery is now o.k., too. Thanks. Unfortunately, I did not get a chance to copy the output lines (from 'see-bstate') when I inserted the battery - the battery is on one side of the XO-1.5, and by the time I had turned the 1.5 over and located the <ctrl> and <C> keys to stop the output, the first lines (upon insertion of the battery) had already scrolled off the screen. Because I noticed that the Battery_LED was no longer dark, I did not repeat trying to capture those "first things 'see-bstate' did after battery insertion". My guess is that the better "support" in the XO-1.5, plus the procedure of inserting the battery *while* 'see-bstate' was running, was enough to "kick-start" the shadow ram in the battery (which had previously been "reset" by running 'bat-rewrite-life' on the XO-1). ---- > Update the 1.5 with the latest firmware and then put the battery in > that machine.

If I remember correctly, just putting the bum battery into the 1.5, then plugging in the AC, did not cause the Battery_LED to light up. > I have bat-debug-log that will log what the state machines > are doing to a log file on SD or USB. Do you have a serial port? Yes, the 1.5 OFW does have 'bat-debug-log'. Does that command take the name of its output file as a parameter? I did not get around to running that command. I do have a serial port (and have used it) - but at the moment, none of my machines has its back off. ---- Thanks for helping me recover my bum batteries. I did not know that 'bat-rewrite-life' (and 'bat-debug-log') existed. How to use them (and other useful commands) is the kind of information that would be helpful to distribute to places where XOs get repaired. [I looked at the DS2756 data sheet - it's NOT a "how to get a battery working again" guide!] Thanks again, mikus _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
