My laptop (HP pavillion dv6700 series) shut off yesterday and now won't turn on. Nothing comes on when you hit the power button, even when connected to the wall. It worked fine yesterday morning, left it sleeping to charge and then when using it that afternoon it suddenly turned off! Is this the battery?

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.

I don't know if this will help, but I had a very similar problem with a DV6700. Pressing on the power coverplate used to get the laptop to boot up. Upon investigation, it turned out to be the ribbon cable from the switch to the board. This is very badly routed and over time, pressure damaged the inner wires. Got a new one from ebay at the cost of £2.00 and I was back up and running in no time.

The DV series of laptops did start to fail and HP were aware of it but did nothing after the warranty was over, common failures were the wireless card port, the speakers and the gFX chip, usually caused by oerheating

About it being an HP Pavilion dv6700 laptop?
Ehhh, giveittome. I will use it.

Looks like I'm going to have to guess since the 'Issue' wasn't stated.

The main problem with the Pavilion dv6700, which is part of the Pavilion dv6000 series of Notebook PC's, is that all the indicator lights come up, but there are no graphics being shown on the LCD screen.
The screen is black.

This is due to a graphics chipset problem, caused by a poor cooling design of HP designers.

The graphics chipset (GPU. Graphics Processing Unit), is mounted to the motherboard in a BGA surface mount.

Instead of pins coming off of the bottom of the chipset, as on the older Processors, there are Solder Balls.

The motherboard has tiny copper pads that line up to the solder balls.
The graphics chipset is set into place, then heat is used to melt the solder balls, and attach the graphics chipset to the motherboard.

Due to the poor cooling design, the graphics chipset overheats, and the solder connections are partially melted.
The graphics chip now has a poor contact to the motherboard.

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

The liquid would have shorted out the laptop and rusted the boards!

You need to go to google and find the serivce manual for the laptop and take it again to clean all the boards up.

the service manual is very easy to follow so you should have no problems at all.

if not you may be best of claiming a new one on your house insurance

after you turn the power buttn on on the computer, do you then turn on the button on the monitor? if you do and still get nothing on the screen, check your connrctions.

Hold the power button in on the computer for 5 seconds. Wait another 5 seconds. Now hit the power button as you normally would to turn the PC on. It should boot normally.
