On a Toshiba LX835 all-in one, is there a way to set Bios Auto On after power outage? It seems like the BIOS on most computers allow this, however, the option is not obvious in the power management section of the BIOS for this model.
It should be in the BIOS Setup under "Advanced Power Management" or APM.
If the option is absent on yours, check the Toshiba website for your country to see if there are any BIOS updates for that model.
However, you shouldn't really update the BIOS unless you are sure it will add the features you want, and in my experience Toshiba's BIOS updates carry no such information other than the version number & how to install it, though I could be wrong where your model is concerned.
Motherboard manufacturer's own BIOS update information is much more informative on their websites, but you must not install any from them. Install only drivers & BIOS updates supplied by Toshiba.
