I would try the following steps, then contact HP (if these don't work, chances are it's hardware related).
1) Remove the battery and power cable. 2) Hold down the power button for 3 seconds. 3) Reattach the power cable and battery. 4) Try to boot again.

best way is to just try out the battery on another laptop, or try another battery on yours. If the laptop is not very old, and I suppose yours isn't more than 2 years old, your battery shouldn't be dead.

My hp pavillion dv4-1220us laptop, won't start up...I press the power button and it turns on for a couple seconds and then turns back off....


1) Is it the battery, power up using the power supply.

2) When the power supply is plugged in, is there a charge light/led (could by a bad power supply not charging or providing a good connection)

3) Is the CPU over heating? Check the vents underneath are they clogged with dust?

After this, you're getting into internal faulty component issues and need someone to look at it.

What is main power supply for a laptop?


I would say that is most likley the motherboard not the power supply and this is a pretty big job you would have to take the laptop apart if the laptop is under warrenty I would use it otherwise you would most likley be better off getting another computer unless you are very good at taking computers apart. You can go to HP website support and get repair manual and it will tell you how to take apart.

Zd7000 mobo not powering up


I've found this particular issue to be common with the zd7000 and zd7000a (the 'a' model especially. For whatever reason, the battery tends not to make good contact no matter what you do, and if the motherboard sees you have one, it uses it. This would be fine, but if the battery loses contact, AC power doesn't come up fast enough.

Sadly, the only realistic solution for the lay-user is to place the computer on a flat, steady surface, preferably something that assists ventilation, and keeps the battery stable and as immobile as possible.. Once you stop thinking of it as a laptop and start thinking of it as a portable computer, it tends to make living with it much easier.

''My HP Pavillion ZE5300 Laptop Doensn't Come On At All!''=v.v=


when you press the power button, does any light flash for 1 second?

remove the memory, hard disk, cd writer from the laptop. then try to switch on again. do it using the power adapter.

if it doesnt come on then its an internal problem. you will have to open the laptop case and remove all parts for test

good luck

I have a compaq presario 700 laptop that is no longer charging.


The notebook battery may have a defect if it will not power on the notebook and if it will not hold a charge. The battery indicator light on the notebook either does not light or always blinks orange. The notebook operates correctly when connected to the AC adapter.
A battery that will not charge may be the result of an AC adapter failure, a system board failure, or a battery failure. Perform the steps below to diagnose the failure.
Troubleshoot the power supply
To verify that the AC power supply is functioning properly, follow the steps below.

1.
Plug the AC adapter directly into a functioning wall outlet, and plug connector into the computer. Do not plug into a power strip, surge protector or secondary power source.
2.
Verify the following operation and take the appropriate action:
*
That all power cord connections are secure.
If the AC adapter connection to the notebook is loose, the connector may be damaged and require repair. Contact HP service and support for further assistance.
*
That the power button or power LED is lit when the computer is on.
*
That an LED on the AC power supply adapter is lit when plugged into an AC wall outlet (not available on all AC power supply adapters).
*
That the AC power supply adapter is the correct type.
Different notebook models require different AC power supply adapters. You will need to know the Product Number of your notebook to determine the Part Number of the replacement part. Click Start > HP Help & Support to view the product name, product number, and serial number that you'll need to have to speak with HP Customer Service.
View the See Also section for information about locating HP Help & Support in your operating system.

Troubleshoot the System Board
If you've verified that the AC power functions properly, troubleshoot the PC's system board by following the steps below.

1.
Remove the battery, and keep the notebook connected to AC power.
2.
Press and release the Power button to start the computer.
*
If the notebook PC powers on , then the AC adapter and system board are functioning properly. Go to Troubleshoot the battery .
*
If the Power LED is off , then the AC power adapter needs to be replaced. Contact HP Service and Support for further assistance.
*
If the power LED is on , but the notebook PC does not power on, then the notebook PC needs to be repaired. Contact HP Service and Support for further assistance.
3.
Shut down Windows by selecting Shut Down from the Start Menu.

Troubleshoot the battery
If you have verified the AC power supply and system board are functioning correctly, troubleshoot the battery by following the steps below.

1.
Insert the battery into the battery compartment on the bottom of the notebook PC.
2.
Connect the AC power supply and allow the battery to charge for 15 to 30 minutes.
NOTE: The Battery Charging light should be on while the battery is charging. If it is not on, check the AC power adapter connection to the notebook PC.
3.
Unplug the AC power adapter cord from the notebook PC.
4.
Press and release the Power button to start the computer using only the battery as the power source.
*
If the PC does not power on, then the battery needs to be replaced. Contact HP service and support for further assistance.
*
If the notebook PC does power on, the battery is functioning properly.
NOTE: If you have purchased a second battery for your notebook PC or you have access to an identical battery, you can also check the battery by inserting the second battery into the PC and performing the Troubleshoot the battery steps again.

Hp Pavilion zd7000 turns on and off with different colored screen


The graphics chip needs resoldering (reflow). Got the same laptop in for repair yesterday. At first when power cord plugged in all LEDS stay, hard drive spins but fans don't work and nothing on screen. A bit later everything's dead. I've seen too many HPs with poor soldering issues. can't really say they're making good laptops these years.
