Hp pavilion not turning on

Yes, but it involves board level component replacement....

An example of what I believe the problem may be, and using the HP Pavilion dv6000 series, and Pavilion dv9000 series of Notebook PC's;

Compaq 615 Notebook PC and Compaq 610 Notebook PC - Maintenance and Service Guide

Wear an ESD wrist strap, and have it's alligator clip attached to a good ground source.

Or replace motherboard at a $100 on up.
(NOT including labor. Just price of motherboard)

Or it may be something as simple as the laptop is dirty inside, plus the Thermal Paste on the Processor has dried up; and Thermal Pad on graphics chipset has dried up. (Cannot be reused anyway)

For additional questions please post in a Comment

Hi

Thank you for your query

Please try the folowing

1) Remove ALL wires and then press and hold the power button in for approx 20 seconds

2) Plug everything back in and then rerty

This may sort the issue out however from what you are descrbing, if there is no boot or display it is highly likely the motherboard and/or the CPU is faulty

I would recommend that you book the PC into a reputable PC repair shop if the above does not work

If this has been useful please leave postive feedback/vote/testimonial - Thank You Again

The lid actuator switch may not be working correctly. It's a small switch above the keyboard and led's on either the right or left side. Try pressing it 2 or 3 times to see if the display starts working correctly again. If so, it will need to be replaced.

If that doesn't work, you can also turn it on with the ac adapter plugged in. After it boots, press the power button and hold it in until it shuts off and then turn it on again and see if the display has returned to normal.

If neither of these options work, your laptop may need to have the backlight replaced.

Hi,
Please try following DIY
1.Remove the battery and press the power button for one minute.
2.again plug in the battery and try to start.
3.open the RAM chamber and refix the RAMs.

CHECK IF U ARE RUNNING ONLY ON BATTERY SO TRY TO REMOVE THE BATTERY AND INSTALL IT AGAIN AND CONNECT THE CHARGER

The only suggestion I can think of trying is to remove the battery and mains lead from the unit wait 5 mins then plug the mains in without the battery present. If the unit does not start after this then it's likely an issue with either the plug pack or the notebook motherboard. Try wobbling the connector going to the laptop and see if its a loose connector. Get the plug pack tested with a voltmeter to see that it's working.
Has the new plug pack got a removable end piece or is it hard soldered, if it's got a removable end piece has anyone accidently reversed this causing + to go to - or vice versa?
If the above tests don't prove positive then I'd say the unit will have to go in for service.
Hope this helps

Hi there, I deal with water on laptops a lot. Even though my answer on this is for a Dog **** on a laptop, it really is the same exact information. http://www.fixya.com/support/t1981284-dog_peed_screen_keyboard_toshiba I hope this helps, Paul

Try unplugging and removing the battery, letting it sit for a few minutes, then plugging in the adapter (battery still out) and try turning on again.

Common problem with motherboard.

To know exact locations of the notebook inner parts, you can try the below manuals of DV2000. Hope this will resolve the issue.
