HP Pavilion zd8000 wont turn on, just blinks on and off
I was attempting to reset the BIOS on this laptop by removing the battery. when i put it back together and pressed the power button, the power button led comes on and stays on, all the other lights blink on and off, as well as the fan, the hard drive (making a wheezing sound) all blink on and off repeatedly and the only way to make it stop is to unplug it and take out the battery. Please help.

They are trash period and even though its an old post I feel the need to complain about this model.. Video circuit issues, Adapters, And charging circuit problems are coming out of the woodwork for these monsters..

Two ways to reset the Bios/CMOS password are as follows:Basically option number is recommended.1. Mechanically, by removing all power to the Bios/CMOS thereby forcing it to reset itself to its stored defaults. You can do this by removing the CMOS battery from *********** board or by resetting a jumper on the motherboard itself (referred to as a "clear CMOS" jumper) 2. By using a program to either locate and identify the password. This programs are referred to as password by-pass utilities or cracks.
Restart the notebook, press F10 and check if you see the BIOS screen or not.
If you see the BIOS screen and if the notebook does not restart in BIOS then this could not be a hardware issue.
But if you do not see the BIOS screen, then perform the steps below :
1. Disconnect the ac adapter and remove the battery from the notebook.
2. press and hold the power button for 30 seconds
3. replace the battery and connect the ac adapter
4. turn On the notebook and check
If the issue persists then remove and replace the memory modules of the notebook and check it.
If the issue still persists then it could be a hardware issue and your notebook needs to be serviced.
visit HP's site, http://www.hp.com/#Support enter your system details then download bios. after downloading the bios. close all open programs. remove any external device. make sure ac adapter is connected. then run the bios update. that should do it. =)
Try just the power supply fromt he wall to the laptop without the battery inserted. If it comes on and then turns off, you probably have a bad power connection. DC power jack may be bad and would need to be replaced or re-soldered.

Try first to remove the battery and connect the AC adapter to your laptop, you will use the power supply directly from the AC adapter without the battery. Turn on your laptop, then if its working normally as it should be,
Then try now to install back the battery then connect the AC adapter, turn it on. If still does not work, perhaps you have a problem with the battery.
a lot of the zd 8000 overheat and turn off, mine constantly does this on hot days of i i dont have enough airflow under my laptop. Also Hp just released a recall for the zd8000 batteries which i just ordered today. I was notified through my email so check yours too
