I'm troubleshooting my friend's laptop. It's an HP laptop. Model dv9620us. When I press the power button, the laptop doesn't boot. All that happens is that the light on the quick play menu light up. The monitor doesn't come on nor does the hardrive light. Have tried removing the battery, disconnecting the powercord, holding down the power button for 30 seconds, and then reconnecting the battery and powercord. Still no success. Not sure if the hardrive is dead or the motherboard, or both.
I used to work for HP laptop hardware support. This is definately a hardware issue. if the screen stays blank that means this is not a HDD issue and that it is definatly a motherbard issue. you can call HP to find out if you still have any warrenty left, if there isnt any left i can tell you that it will cost about $400 to send it in.
Ypu can try reseating the RAM (pull it out, put it back in) and you could also try that with the HDD, buts it a 50/50 chance this will work.

Please check whether the laptop power button may be in the pressed mode.. please release the key. If the key is not released after you pressed the power button, the laptop will power off.
Clean the power on button.
Hope this works..
Its an old trick that got my Dell laptop working
Unplug the laptop
remove the battery
press the power button,...nothing will happen,
wait a few seconds
put battery back in laptop
plug it in
hold upside down
press power button until it boots
If that doesn't work it could be a bad/loose/dead bios battery
What is the model of the laptop?
> try some basic troubleshooting:
>remove the batt from the laptop
> unplug the ac adapter
>remove any external device from the laptop like usb....
>press and hold the power button for about 10 to 20 secs...
> plug the adapter and return the batt
>turn on the laptop....

Here is a fun fact about this HP laptop....the keyboard want to be grounded before the laptop will fire up in certain situations. Make sure that the three screws are secure in the battery compartment that secure the keyboard and there is another screw inside the memory compartment that has to be secure. You can tell its the keyboard screws by the keyboard icon embossed in the plastic. Also the ribbon cable that carries the input signal tend to go bad in these, especially around the fragile ends. You can get these cables on ebay for under 7 bucks.
We can further isolate the issue by connecting an external monitor to the notebook. If the display is fine with the external monitor, this clearly indicates that the issue is related to the LCD screen. Otherwise, it is due to the some other internal hardware.
You may follow these steps to connect the notebook to an external monitor.
1. Turn Off Computer. 2. Connect the monitor cable from the monitor to the monitor port on the rear of the computer. 3. Connect the monitor to a power source and turn it on. 4. Press the Power button to turn on the computer.
* Switching the display to the external monitor
Press FN + F4 to toggle the display between the Notebook display and External monitor.
1) plug YOUR power adapter into your friends hp dv1000, see if it turns on laptop.on. If yes, then u have one less problem. 2) to trouble shoot a laptop takes a lot of skill, stuff is very small, things could be damaged just by pulling the wrong way. you would HAVE TO BE very carefull. Look for the trouble shooting manual 1st. or find a good technical person.
