Hi there
I have a acer aspire 7530G i havent use it lates becouse my screen stay black but i got video on the vga port (the hdmi allso show nothing)
So i used it with a tv but those days the laptop have no boot at all allso no picture and the fan start and stop after 3 sec. Any idea what may hapen ?

How old is this system? It sounds like a motherboard problem, such as bad capacitors, bad solder joints, etc.

I recall this model to have issues like that. Your choice to google it up and find out what folk did before. If this hit our shop counter the estimate could send the owner away crying.
