I have a HP Pavillion dv6700 and when I turn on the power the screen does not come on

You will have to replace the HDD

Hello.The most common reasons for power issues are the battery, power jack and power adapter/cord.Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.If you move/wiggle the hp pavilion dv6700 power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.If no change, the power adapter is probably faulty and needs replacement.Hope this helps.

Hi, believe it or not?; sometimes the current in certain areas of the home or apartment have separate power circuits from the main direct current system. Check to make sure there is electrical current running through your socket, and or light switch to open the circuit. Thanks, paul7of9

Bad battery.

cpu is not getting the power coz the smps is not supplyin power to it so change ur smps or chk its wires

its possible that the presentation mode is on

press the Fn key and F5 keys together (might have to do it several times)

that should do it as long as the system is functional

i afraid that cause by hardware, but try to remove battery and only use the power. or press F2. if prsseing f2 the new screen(bios) open try restart and press F8. tell me is it work or not
