Toshiba Satellite C50-a Bios Update [upd] -

If you restart your laptop and see a white or grey screen saying "InsydeH2O," do not panic. This is the firmware provider Toshiba uses. If the computer stays on this screen for more than 10 minutes without progress, it has likely frozen. You may need to force a shutdown (holding the power button) and restart, but this carries a risk. Always ensure you are downloading the correct region-specific BIOS (usually European or US models differ).

The BIOS (Basic Input/Output System) is the firmware that lives on a small chip on your motherboard. It is the first software that runs when you press the power button, initializing your hardware before handing control over to Windows. toshiba satellite c50-a bios update
