Re: Page Fault message on XO-1 and another Fix Clock question

Reviewed, thanks. thanks a lot for the quick reply. Looking at the wiki now and given the number of invalid system date issues we saw on other machines I assume this is a case of the page fault message situation described on http://wiki.laptop.org/go/Fix_Clock# If_the_screen_does_not_turn_on. Yes, this is likely. Turns out this was indeed the issue and I now fixed it. Or are there any other issues which could produce such an output? There might be, but if you have a version before Q2D05 which was released in 2007, there's almost no chance of anybody remembering anything useful. It has been more than five years! To verify that the Page Fault is happening because of the known problem (ticket #5391, svn 752), please use the Open Firmware ok prompt to display the values in the real-time clock, using the .clock command: ok .clock If the month is invalid, then the Page Fault is most likely to be the one expected. Another method would be to take an XO-1 with Q2D06 or earlier, remove the clock battery, force the problem again, and see if the serial log looks the same. I expect it will. There are other methods to diagnose, but these require immediate collaboration with a firmware engineer, and I don't think it is worth doing that yet. (2) Mike sent me a bunch of ML 1220 batteries as replacements for the XO-1 units which showed the invalid system date messages. However even with the new batteries in-place, after verifying that the (old) battery holders looked okay and having set the current time on the command-line the system date reverted back to 2000-01-01 00:00:00 after every reboot (and hence the invalid system date message kept coming up again). Any suggestions on what to do in such a situation? Charge the battery before the power cycle test. On the XO-1, it will recharge from the main power source while the laptop is powered on and fully awake (not suspended). When recharging an empty battery, it is expected that the battery will reach normal voltage levels after around 30 minutes of charging, but will require potentially 24 hours for a complete recharge. http://wiki.laptop.org/go/Fix_Clock#RTC_power_dynamic has the above text. Thanks a lot for that information, I had somehow managed to miss it. I'm now charging the four XO-1s which are here in the office and still displaying the invalid system date error. Let's see whether it works out. FWIW: Still no luck even though they have been charging for an hour now and automatic power saving is turned off... :-/ However seeing that I have to leave the office in 2~3 hours to catch my plane back home and the laptops do work just fine (outside of displaying the error message at the beginning) I guess I'll just have to leave it at that. Cheers, Christoph Check that the battery voltage is reasonable. Check that the connector is passing the voltage properly to the circuit board. Unfortunately I don't have any measuring equipment here so I can't do that. Also, please make sure you upgrade the firmware as soon as you can, so that you aren't impacted by this problem any further. All of the concerned XO-1s which have this problem are running firmware Q2F12 (and 12.1.0).
