Considering the system is approaching 7 years old and if you still have the original laptop battery installed, it is more than likely that the laptop battery and CMOS battery both need to be replaced. More than likely the BIOS is corrupt and would account for the option being greyed out. This support page has more information on recovery. And it is very possible, if corrupted, that the CMOS battery may be the cause.
Hi there i have the above Laptop in my possession. Whenever i boot i am taken to the BIOS recovery menu with 2 options: Recover BIOS & Reset BIOS but the continue button is greyed out. In red the power status shows: Inadequate even though the battery is seated correctly and the charger i've been using without any issues the past couple of weeks. I do not want to purchase a battery for such an old laptop, is there any way to reset the BIOS without having to? Any help appreciated.
