touchpad and keyboard of my HP Probook 4510s not working

I am unable to use my laptop's touchpad and keyboard. Even my mouse is operational only when the windows is loaded. Meaning, during the booting time when i wish to change the booting option, at that time i am unable to use even my mouse. Which otherwise is the only outside device used via usb port. Earlier there was issue of BIOS application, which was corrupted, which not is visible when i just boot, meaning thereby, the button namely f1 or f8 is operation at the time of booting, but unable to do any change in the booting options which are visible when i just boot my laptop. Though with the help of USB i am able to work on my externally attached keyboard. What should be done to cure this issue this is persistently bothering me for last 15 days. I am unable to make my laptop's touchpad and keyboard operational. 1 thing more only Tab is operational and opening and closing bracket keys work that is it. And as i said now only f1 or f8 works during the booting, nothing else. Please get me out of this trouble. I've trying for many days. But unable to get rid of this issue.
