I have three years old HP Laptop (HP CQ42). It was working just fine till yesterday. Yesterday, I left my laptop turned on for about half an hour. When I came back, there was no display. Only "Caps Lock LED" was blinking and "WI-FI LED" was red. Now, when I try to turn it on, I can hear the fan/HDD spinning but there is no display (only blinking Caps Lock LED and red WI-FI LED). I tried to turn on my laptop with battery and without battery (on ac main) but no luck. I also, tried to reset BIOS by taking the battery out and pressing power button for 30 seconds. Still my laptop is not working. Is my motherboard dead? Please help.
