Witam . Problem dosyć nietypowy.
Jak w biosie mam datę prawidłową 2016.08.26 system Windows 7 wskazuje mi 2010.08.20 i złą godzinę. Bateria (a raczej akumulator ML1220 3V ) sprawny dla pewności resetowałem i podmieniłem na nowy.
Bios zaktualizowany z poziomu Windowsa ze strony producenta do najnowszej wersji .
System z Windows 7 z recovery przywracany , instalowałem też czysty system Windows 7 na innym dysku objaw ten sam.

Zmiana daty w systemie skutkuje resetem daty i godziny w biosie do 2009.01.01 00:00 i uruchomieniem się systemu z datą 2008.12.31.

Jeżeli nie ruszam daty w systemie to data w biosie jest prawidłowa i nie kasuje się po ponownym uruchomieniu .

Co dziwne w biosie jak zmienię datę o parę miesięcy i lat do przodu to o tyle samo miesięcy i lat zmienia mi się data w systemie .

Przywracałeś ustawienia domyślne w BIOS? Robiłeś CLR CMOS? Spróbuj zrobić bios z poziomu pogramatora. Jeśli nie pomoże, możliwe uszkodzenie obwodu RTC który znajduje sie w PCH...
