A1278 Date & Time resets on Power on or restart

[scooterck]

Hi,

I hope somebody can help me, I have a Macbook Pro A1278 (820-2879).

It came in totally dead and no green light on charger. Repaired the water damage, and thought I'd repaired the Macbook.

But the customer has brought it back with a weird problem. The date and time keeps resetting to 1999 and 00:00 when the Macbook is powered on or restarted.

This is with a battery that is 100% charged and also with the charger plugged in.

Can anybody help with where I should look?? I have checked the RTC voltage and the 3.42 is present.

There is no RTC battery, can anybody help, totally scratching my head on this one

Respect

Hi,

MBP noob here. Im using A1278 also.

Just a thought; have you tried PRAM reset? because I think date/time stays in the Vram (or maybe NVRam).

After that I would try SMC reset just to sure. And as a last resort maybe clean Install of the OS X.

Sorry, maybe I am giving wrong suggestions, but I have no idea about RTC voltage etc.

Hope it helps,Good Luck
