ibook without battery

Message #1 - Posted 2006/07/24 - peyoting

A ibook without battery loss time& date after a seconds or minute, i think that it is because thay use only a condensor instead battery for clock (old imac and pcs).

When you enter in mac os it warn you that using with bad date could cause problems. had anyone problems for use with a 1970 date?

Is possible change date& time from open firmware?

The simplest way is to network it, and set it to make automatic time server lookups.

On my machine, in OS9.2 with AppleScript 1.8.3, the following script runs at every start-up. I wrote it when I had problems with a failing battery. It's run perfectly, and usefully, since 2003.

You might need to adapt it to your version

-- This is a finder script
property checky : 2006

tell application "Finder"
activate
set y to the year of the (current date)

-- New Year kick forward
if (y is equal to (checky + 1)) then set checky to (checky + 1)

-- Vet for gross discrepancy, including in particular 1904 and 2040 if (y < checky) or (y > checky) then

--- *** Put these two lines into a single line
display dialog "Warning: the system is set to year " & y & return & return & "Reset the date NOW!" & return else
display dialog "No date warning" & return giving up after 1 end if
end tell
