Why is my laptop displaying “…BIOS is not ACPI Compliant” and failing to boot up?

My Toshiba Satellite L500 has a problem. It won’t start – it reaches the Windows Recovery screen and highlights Windows Repair not Start Windows Normally, then it brings up a blue screen “…BIOS is not ACPI Compliant”.

NB Earlier I had ever replaced the hard disk and put the laptop on AND also the Keyboard is not responding (the NUM LOCK light flashes on start BUT even pressing F12 brings a menu page but I can’t move the Arrow keys). Many said it was the faulty charger or the old battery am using. Help me.
