Question about HP Pavilion zd8000 Notebook

1 Answer

Battery or power cord problems

My HP zd8000 laptop will not keep a charge on my battery and my ac power adapter keeps cutting off, which causes my windows XP Home  operating system to cut off.  This has corrupted my operating system and the power cord will not stay on long enough to install / repair the operating system again.
Thanks  Gregory

Problem sounds like the power pin ... where the AC cord connects to thecomputer. That particular component is very fragile. The part torepair it runs between $ 5-$15 but the labor to repair it will costanywhere from $ 100-$250. It can be repaired by you if you are verycareful taking the system apart. Just pay attention to every detail ofyour dis-assembly. I also recommend you get one of these to stop the problem from happening a 2nd time.

My NEC Versa 3200 laptop screen now keeps on turning bright and then dim for few seconds and then back to bright. It does this few minutes after stat up. Any advice on this, thanks.


Generally a laptop will do that when it changes from AC power to battery power and visa versa. The tendancy is that either the power jack is going bad or the power cord has a broken wire near the head. Another reason laptops do that is if the AC adapter is not rated for the laptop it's being used for. Like, if you were to use a Netbook charger to charge a full size laptop, you will get the same problem. Check the charging cord for and abrasions or cuts and move the wire close to the head around in circles and see if it has a "sweet spot". Take the battery out and try starting the laptop on AC power only. If the problem is in the cord it should shut the laptop down or keep it from coming on. Either way, it's most likely one of those three things. Hope this helps

I have recently purchased a replacement battery for my HP zd8000 laptop. The problem is that the laptop is calibrated for the old battery and doesn't appear to even want to charge the new one. Any help...


You should first try to recalibrate the notebook and battery using the following steps: (this should be done every three months also as short charges and discharges really mess it up and will give you a false reading)

Step 1 - Disable the Windows Power Management

In Windows, right-click the Desktop and select Properties in the menu list.
Click the Screen Saver tab and then click the Power button.
Under Power schemes, select Always On in the drop down menu.
Under Settings for Always On power scheme, select Never in each of the drop down menus.
Click OK on the Power Options Properties window and then click OK on the Display Properties window.

Step 2 - Fully charge the battery

Connect the AC adapter to the notebook.
Charge the battery until the Windows battery meter is at 100%.

Step 3 - Fully discharge the battery
Remove the AC adapter.
Keep the notebook on until the battery has completely drained and the notebook automatically turns off.
Connect the AC adapter to the notebook.
Keep the AC adapter connected to the notebook until the battery has completely charged.


Step 4 - Enable the Windows Power Management

In Windows, right-click the Desktop and select Properties in the menu list.
Click the Screen Saver tab and then click the Power button.
Under Power schemes, select Portable/Laptop in the drop down menu.
Click OK on the Power Options Properties window and then click OK on the Display Properties window.

Now...
If you go into Control Panel, Power Options, and select the Power Meter tab, what does it say?


If you are still having issues, then do the following and then go back through the recalibration process:

Try going into Control Panel, Administrative Tools, Computer Management then down to devices and there should be an entry for batteries. Select that and right click to select scan for hardware changes.

My ZD8000 went off and will not come back on. First I thought it was my AC adapter b/c I had it do it before and I replaced the AC adapter and it was fine, but I got a new adapter and still it will not...


MOSFET on the front end behind the DC Jack is open. Usually an AO4407 (alpha and omega -30v 12a ) or FDS4435(fairchild -30v 11a) This will keep all voltage from going into laptop.

No power indicator
No charge indicator
No response to power button being pressed

HP zd8000 will not boot on battery


If every thing is correct ( the Battery, the AC adapter, etc ) then also the Power light is not turning on, then somewhere the power is not transmitting. The laptop must have a internal connection Breakage. Oh, I saw that you didn't mention AC Adapter. Have you checked it. Also check the the Control Board of the Laptop. Better you give it a Servicing.
Thank you Sir, Have a nice day.

Hp notebook zd8000 wont power on


In this case i suggest you to remove the battery from the notebook and try to power on the notebook with the help of AC adapter so that you come to know whether the issue is with the Battery or AC adapter. If still the notebook is not getting power with AC adapter you need to take for service retailer store and fix the issue.

Charger/power cord not working


your problem might not be the AC adapter but the AC jack of your laptop. if you cant keep a charging icon steady then maybe the AC jack of your laptop is loose already. you might need the help of a guy knowledgeable in electronics to help you out with this one.

Battery won't charge


These use a new generation smart adapter with a data circuit. Try another battery first but if it works fine on adapter it should not hurt anything. These models are also coming out of the woodwork with charging circuit failure, Video circuit failures and more. Good luck!
