We have managed to find out more information regarding the ICH6 issue of
causing the real-time clock (RTC) circuitry to be susceptible to excessive
leakage. This leads to failure to boot up or to freeze. According to our
sources, ICH6 is draining the CMOS battery so fast that it will be flat in a
month or so. The ICH6 will continue to drain the battery even when the system is
not powered up. A replacement of battery will certainly allow the system to boot
up again but it is not going to last for long till the battery is drained. According to the
DigiTimes report,
the affected ICH6 southbridges are manufactured between June 7 and June 14 which
is Week 20. So far, most of the 925X/915 boards from the Taiwan manufacturers
come with Week 21 ICH6 and only few early boards are paired up with the “SECRET”
ICH6 ES of Week 20. However, it is still unclear if the issue will affect
batches later than Week 20.
