Re: RTC battery low or CMOS chksum inconsistent on a new Tecra M4 ?
in response to: Andrej
Please check user`s manuals. I have found interesting info about that on page 137 and 139. The fact is that unit must be connected to AC adaptor, the battery must be full charged and just in this case the CMOS battery will be charged.
Charging time is about 8 hours but you can leave it for a longer period on. I recommend you to leave the unit on over the night (not standby or hibernation). Before you do this check standby and hibernation settings in power management. You can set the “display off” option to one minute because the display must not be on all the time.
