My hp pavillion dv6700 laptop won't turn on.

You will have to replace the HDD

Hi have you tried to power up without battery?

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.

sounds like a defective battery, check the hp site for a recall if there is none hopefully it's under warranty.
