1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced.
4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
5. The power button could be bad.
6. The motherboard could be defective & needs to be replaced

How do i fix my LCD?


Hi,
I have got a hp pavilion dv5000, when I turn on it the screen goes blank.

Power led glows, I hear for a few time the fan, disk led flashes intermittently and also I feel that the DVD player tries to load.

If I try to click on caps lock or num lock, leds don't respond to commands. I tried the hard reset pressing the power button for 30 seconds with the battery and the power removed. Nothing to be done by connecting an external monitor....

What can I do ?qqb002.gif

Thank you

I have an HP Pavilion dv7-1130 Entertainment Laptop, and as of recently, when I try to turn it on, the lights around the keyboard power on and the fan runs, then the fan stops and the lights stay on. No...


With an extensive use of the notebook,
some times notebook would store some static charges which
indeed will stop the notebook from powering up or charging
the battery. The procedure to remove this static charges from
the notebook is known as power drain. Performing a power
drain procedure will not effect any personal data or delete
any pictures from the hard drive on your notebook.
I recommend you use Power Drain procedure by following these
steps:

1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter.
5. Turn on the Notebook power.

I have an HP Paviion dv9008nr Entertainment -black screen at boot


Unseat and reseat the memory one stick at a time in each slot on at a time. After each reseat of the memory, turn on the laptop and see if you get video. If you still don't get video, go ahead and take out the hard drive and the dvd drive.

Then try turning on the laptop, if you still don't get video then the motherboard is bad and you'll need to get it replaced.

My HP dv9208nr laptop screen is black after I power it on.


Hi:
I am sorry to tell you that this series of HP laptops has a known problem with the video chip on the motherboard. There are thousands of complaints to HP about the DV9000 seriies laptop, and yours has the same sympoms that others have reported. HP extended the warranty on some, but most people lost their shirts. There are a few people who have had mixed success in repairing the motherboards, but often they have to get replaced. If you did a google search on yor laptop problem, you will find lots of info.
The bottom line is that your laptop is expensive to fix, and it is a known problem!
