I've managed to open my pc but it took me two hours.and the bios is 1.03 and the latest bios is 1.11. Also the date and time is wrong but every time I put the correct date if I close my pc everything is lost.they told me that I need to update my bios but i can't do it without a working battery... I get an error because of the battery.
