Hello !
I have a Hp nx 6310 laptop, and recently it developed a problem, like the laptop starts but the screen remains black although i can hear the cd-rom running and no beeps as if it would boot.
No sound no image, no nothing, only the ON button.
Thank you !
Connect the notebook to a power source using the power adapter. Press and hold the Windows key and the B key at the same time while the computer is off. While still pressing both keys, hold down the Power button for one second, and then release the Power button and the keys.
Perform a hard reset
Disconnect all peripheral devices and remove all USB devices and SD media cards.
Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds to drain all residual power and restore default startup settings.
