Hi all, i have a problem with my laptop, the brand is compaq presario CQ40. The problem is when i turn on the laptop, it does not appear anything, it is just black, but the power light is on, and i can hear the fan spinning and all except the hard disk light is off. It is the hdd that the culprit? or motherboard? Opinion please.
could be the back light on the lcd has failed..can you with a flashlight see anything on the screen. if not plug a monitor into the laptop use one of the f keys to turn on the ext video port. if the video comes on it the lcd screen.
