    I have the same symptoms. I am considering purchasing a replacement motherboard, but i am concerned that it will be subject to the same problem. When diassembling the laptop, I noticed that the screw closest to the video adapter area had been installed crooked, I am curious if this has to do with the problem.

I have split screen. When I turn my laptop on, the screen is divided into four and the hp sign is very faint in all four screens.

after doing some research, this laptop has a history of this happening, the only suggestion i read that seemed applicable is to try a system restore. i know this really doesn't help the problem as it's like curing the disease by killing the patient, but i'm not sure what else to try

Hello, My HP dv9000's screen has split into four horizontal parts. They are all slightly yellowish and it is almost impossible to read anything in them. Please can you help?

I suppose you must have a Nvidia Graphic card in your laptop....

This is a very common problem with nVidia geforce 8400 and 8600 cards.
Serach google with this "Defective Nvidia geforce card" and you will see lots of user facing same problem in HP, Dell etc..

I too have an Hp laptop with nvidia geforce 8400. I have faced similar problems(screen got divided into 8 parts) in past for 3 times. Every time I have to replace my motherboard at HP service center.... It is caused by overheating of laptop that destroys the nvidia graphic card.
Go to the service Center and ask for a motherboard replacement.
hope this will help.....

When i power it on i get four beeps four times and it won't boot and shows nothing on the screen i.e. dark screen the make is thinkcentre lenovo model and after i decide to shut it down by long pressing...

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.

Blinking mini notebook screen

Your notebook/mini is designed to power down the screen if your battery begins to lose charge, and this may be considered normal until the battery is recharged.
Try replugging the power then press the power button to take it out of standby mode. If it still hangs on the blinking light, you may need to update the bios or change your power settings in bios to either S1 or S3 and see if that changes anything.
