Is there PRAM battery in A1286?
Recently on start-up, warning appears that time is set to early 1900s or something. Until synced to Apple Internet time, date/time is off and Keychain seems to have lost some functions. My recollection from prior Macs says internal physical PRAM battery held these settings. But I find no reference to such in About Mac or iFixit for this model.
