hi, please help me
when i power on, i can see clearly the hp logo then all it's dark.
if i enter into the bios i see it, but very very very dark
if i put an external monitor i can't see the bios, but when windows boot, i can see clearly the operating system on the external screen and use the pc without problem!
another strange thing, soon before windows boot, the arrow point appears for some seconds than disappear
another strange thing: when i disconnect the external monitor, some times the internal monitor power on and i can see clearly!
if i disconnect the battery and the power chord, holding power button and the i reinsert the power chord, i can boot into the bios and see the bios for 2/3 second
i've try another screen and another inverter: still the same
here's the problem
