Friends,

My HP Probook lappy could not log on when switched on. Model - Probook 4460s, Windows 7

I have run HP security by F1.....F10 (Lol!) and sparing much time to restore this lappy.

When switched on , only HP logo appears on screen and blinking on and off, on and off constantly.

Guys, any home remedies or DIY tools before takes it to technician ?[DOUBLEPOST=1556772848][/DOUBLEPOST]No responder :joyful::nailbiting:
