Unfortunately I experience the problem, that under some [1] conditions the RTC does not keep time. It runns in advance compared to the real time, up to several hours per 12 hours of time. The machine is quite new, so I don't think, that the RTC-battery is already exhausted. I was able to gain the information that the RTC in this notebook is a BQ3285LF (is manufactured from TI - Datasheet for instance at http://www.scanti.ru/docs/datasheets/slus183.pdf - and probably others). Is such a problem known to you? Is it possible that it is a kernel issue or do you think it is a hardware-bug? How could I debug this issue? Thanks a lot for any suggestions Maier Gerfried [1] I was not able to find out under what conditions. I first thought that it could be temperatore-dependant, or if the power supply is on line or not, if I booted windows before. Unfortunately I was not able to find the reason by now. --
