Hp pavillion dv9500 not turning on

Please re-submit your problem stating more details. Thank you.

unplug the ac adapter from the laptop and remove the battery
press the power button for about 5-10 secs

while the battery is out, plug in the ac and turn on the computer if still doesnt turn on

use a known good adapter and plug it in if it still doesnt work then motherboard needs to be replaced

hope this help

check the power supply

yes thia is right,and these a electronics tech. area. try to go repair shop, to change-it. Dont try to replace, bacause you dont have necessary tools. there is 6 to 8 layer motherboard, normaly you damage the motherboard, if you try.

1.remove the battery and disconnect the power cord from the laptop. 2.hold down the power button for 1 minute 3.now connect it only to the power cord.keep the battery away 4. as soon as you press the power button to turn it on, keep on tapping F8 key. 5. If you see advanced option, you can choose safe mode with networking and it hit enter. 6. now remove the security like Norton or macafee and scan it with malwarebytes(www.malwarebytes.com) 7. Now, restart the computer 8. If data is not important you can restore the computer to the factory setting, but all of the data would be lost. 9.to restore the xp computer start press F10 at the startup 10. to restore the vista computer start press F11 at the startup.

Is the charger working? Check the output connector.

scroll to the bottom of the page to the "see also" header. Choosethe download youcam file. It is a binary file that can be saved to your hard drive and then installed.

This question requires a techincal person to first, attach an external monitor to the laptop to see if there is video going to the external monitor? Then while the external monitor is hooked up he should run full diagnostics to see if the motherboard video adapter is fully functional? If it is? He has to open the laptop and trace to see if the plug from the motherboard to the monitor needs to be reseated. The worst case scenario is you will have to replace the motherboard.

Yes There are several layers that can crack and you may not feel it on the surface

This problem occurs in some specific computer models because of a conflict between SP1 and the system BIOS. The best way to correct this problem is to download and install the correct BIOS for your computer.
