Question about HP Pavilion zd8000 Notebook
Started 3 months ago with one vertical pink line. Now have 4 thin lines plus a 2 1/2 inch one that is difficult to see through. Laptop will be 3 years old in May. Love it a lot!
Time to look for another?
To date, HP has refused to repair these defective laptops despite being fully aware that the problems do exist. The only real solution that I'm aware of is to write to the BBB (the one in California located near HP's Executive Offices). HP agreed to repair my laptop at no charge after I went this route. To the best of my knowledge, they replaced the display as I no longer have the vertical lines. It appears that they may have also reduced the processor speed as the computer runs much cooler than it ever did before HP made the repair. It's been several months since the repair was made and, so far, no problems whatsoever. Hopefully that will continue.

The problem is a faulty LCD display, you'll find that this is the problem with most if not all zd8000s, HP refuses to admit there is a problem with the screens. The over heating problems/low battery life/power adapter problems can be attributed to having a Pentium 4 that is over-clocked and running at a higher voltage level (operating currents are around 7 to 10 amps, most home electrical outlets are breakered for 15 amps), unlike most mobile technology processors which operate at a lower voltage & current. This in-turn causes damage to other components inside the laptop including the processor (routine crashes).
What I can suggest to help the cooling situation is to routinely pull apart your laptop as per the manual and clean out the cooling fins for the CPU heatsink as well apply some good heatsink compound between the CPU and heatsink for better heat transfer (the 3 fans on the bottom sure **** up alot of dust and pet dander), remove the battery and operate it as a desktop (charging circuit adds quite more heat generated inside the laptop). lets face it this was a poor design for a laptop, we purchased a glorified desktop.
As for the LCD display, I would suggest replacing the 17" display with a commercial replacement ($150-$250), or add an external 22" display for the same price

If these verticle lines are present even before computer boots into Windows, you need to replace your LCD screen. If lines only show up while in windows, try reloading the display drivers, but most likely a bad LCD. Very common.....The verticle lines can vary in color, from red, pink, yellow, etc.

Filing a complaint with the BBB may prompt action from HP.

This is a overheating problem. Usually it is not the video card. You can confirm this by plugging in a monitor. Are the lines on the monitor? From my investigation of my Toshiba Satellite A25 (17") and now the HP z8000 (17") it is a wide reported problematic generation of these laptops. Toshiba knows this problem very well and is totally ducking the accountability by my experience in dealing with them and as far as I know by the reports that I have seen on the internet with others dealing with these issues. I have contacted Toshiba repeatedly and get no help and only false promises of return calls. Now, I was given an HP z8000 as a gift which turned into a nightmare. It is only two years old, shuts down in about 5 minutes. Runs very hot. Can't change the operating system to test if there has been some corruption of the installation on the hard drive (caused by overheating). I have asked some technical people about this generation of laptops. They are clocked to high (according to those that I have asked) and therefore they are running way to hot for the architecture (existing design of the unit and cooling).
A very plausible resolve to the overheating is to clock your laptop far slower (say 60 percent, perhaps even 50 percent). That way the cooling should be adequate. Manufactures have done that with the current generation of "dual processor" units. Two units running in tandem run cooler (easier to cool). Only one processor runs at a given moment unless there is a very high processing demand (usually doesn't happen with most computing). If the demand is high it usually doesn't sustain that demand for very long.
If anyone knows how to reset the clock speed I would appreciate and email (firstname.lastname@example.org)
One other point. I just heard that there is a class action suit pending against HP regarding these laptops. I found it by doing a google search. Something like..... hp laptop class action.
Hope this helps some of you.

Not a solution, just an observation - at one point, I noticed that almost every day a new line appeared. I pulled the battery and am running strictly off of AC. No new lines since then. My only guess is that a "couple of year old" battery generating heat contributed somewhat to the overall problem.

Here is a link to a replacement display screen http://www.screentekinc.com/ppc-series-zd8000%20lcd.shtml?gclid=CJHZhb6ElZoCFQXGsgodrU22Mw
several problems that you can address yourselves:
1st keep heatsinks cleanby blowing them periodicly with the canned air you can buy. 2nd key stroke skipping is a symptom of your battery going bad pull it and run off ac and your keystoke problems go away so replace the battery. 3rd the screans last about 3 years and then the lines apear. replace the screen not hard if you love your zd8000 or dv8000

I have similar problem with several line on the screen of my computer.I first changed my inverter board but the lines remain the same.I gues is the partial failure of the LCD which will eventually pack up later.So the best bet is to change the LCD.

You guys have got to be kidding...
1. HP will NEVER EVER admit anything is wrong.
2. BBB has little push at HP, the fact that one person got it pushed through is quite a good deal, but don't think it will happen for you just by complaining.
3. If the lcd pane is more than $50(US) then scrap the thing and get a new machine.. Dell has good low end latitudes that will run circles around this pig and do it for < $700 us...
I have one here from a friend and I repair computers for a living. I told him that it was simply not worth the effort or dollars. Peel the MS Media center sticker off the bottom AFTER you copy off the license key, and toss it in the good will bin.

I have the same problem, looked in to it a bit and it appears to be the graphic card which is faulty, makes sense when you look through other peoples comments.
