Blinking red battery light on XO-1
rich...@laptop.org said: Blinking Red is error. Next time it happens can you please boot to OFW and do ok watch-battery Then press a key to make watch-battery exit. When it exits it will tell you what the error is. Please pass that on. I just got one. When I got to OFW, it told me the lid switch was active and gave me 8 seconds before it powered off. On power up again, it was fine and the battery light was green. I wasn't smart/fast enough to notice when the battery light stopped blinking. Is there anything I can do while still running Linux? -- These are my opinions. I hate spam. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Presumably the lid switch was not actually active and the EC was misbehaving. Onk XO-1, the magneto resistive sensor for the lid switch is connected to the embedded controller, and this advises Open Firmware of the lid being closed. To avoid it powering off, type lid-off and press enter. Yes, you only have eight seconds to do this. That way you might have been able to use watch-battery as Richard had suggested. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

The printout said that, but I didn't even get started typing before it timed out. I'm not sure where 8 seconds came from. If that happened often enough I'd probably be able to do it fast enough. But that was the first time I had seen it. I wasn't quick enough to read and understand and type. Remember, I was trying to not destroy the evidence so I was going slowly. - Something similar happened a few months ago which is why I saved Richard's message. I have a hack script that reboots the XO every 4 hours. It's got a patch to check /sys/class/power_supply/olpc-battery/error and log the answer instead of rebooting. The error was 20 (Sorry I didn't remember to look there earlier.) -- These are my opinions. I hate spam. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Remember, I was trying to not destroy the evidence so I was going slowly. Sure, not a criticism, just making sure you have the tools you need. The eight seconds comes from here: http://tracker.coreboot.org/trac/openfirmware/browser/dev/olpc/lid.fth#L6 There's a two second delay before the message appears. The timer starts as soon as ok is printed. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
