Dell Vostro 1520 notebook running Windows 7, worked fine around 2 years,
but today got problem: when tried power on, it not load windows, stay black
screen, and three active(On) indicators: numeric keypad icon(flashing),
caps lock and keylock symbols.
I tried unlock keyboard by by pressing keylock key, but this not help.
Laptop not load Windows, nor allow shut down it via pressing "Power"
button. I only can shut it down by unplugging power adapter jack.
Notebook was powered from AC power supply, as internal battery was removed.
I tried with installed battery, but as soon I swith the Power on, it just
shut down after second or so.
Is this hard disk problem, showing hard disk failure?
