Question about HP Pavilion zd8000 Notebook

1 Answer

Zd8000 powers on for a few seconds then powers off then loops forever

It never gets to even a bios screen. Ive noticed the middle fan on the bottom isnt turning. Is that the CPU fan and therefore the reason why its shutting down to avoid overheating the CPU? Thanx in advance.

    hi atiqq, Are you saying that the cpu fan will not start at bootup and only when cpu overheats? Also, how can I update the bios if the update from HP requires that I run it from inside WIndows XP when I dont even get to desktop or even bios screen?

    I have the same problem, i believe a Crisis Recovery Disk is the way forward checkout this link to hp's forum

    the problem is getting hold of the bios the version i believe is needed is f.32 but have so far been unable to find it. If anyone has a copy on their laptop or can let us know the manufacturers site and any specific details this would be very useful. Then there is the problem of getting it onto the laptop not having a floppy drive, and external drive doesn't get any power at this point (for me at least), the dvd/cd appears to read the CD but stops quite quickly this maybe because the bios.wph file isn't the correct file. Any how... this is a work in progress with many people experiencing the same problem with varying degrees of success.

Acer aspire 5551-2036 wont come on..

I read your description carefully, there is no dought in my mind that the motherboard is the issue,acer is well known for problems in that area and unfortuneately there is nothing more you can do, generally I find they get to hot, cooling fans fail, and numerous other situations.

I turn the laptop on but it immediately turns off within seconds

1. First step is to check if the laptop is overheating:
  • Does the bottom feel very hot to the touch
  • Is the CPU fan not spinning up
If it is hot to the touch and the CPU fan is not spinning up, this will cause the system to overheat and shutdown as a safety feature. In this case the fan would either need to be cleaned or replaced.
2. Failing hardware can also cause this (i.e. a failing motherboard, CPU, Battery, Power Cable, internal PSU, etc.):
  • Did you notice any system freezes or slow down prior to this happening
  • Have you noticed a sharp decline in battery life
Try disconnecting the battery and then only use the power supply cable to power up your laptop. If the problem still occurs, then reinsert the battery and remove the power cable and attempt to start up the laptop with only the battery inserted.
3. In some cases this can be caused by a malware (virus) infection. The infections that cause this can sometimes be remedied, but usually require expert assistance and the remediation process is very specific to that type of infection.
  • Does it get to the first splash screen (i.e. the BIOS splash screen)
If it doesn't get past (or even to) the BIOS splash screen (usually a Dell Logo) then that would point towards it being a over heating issue or Power issue.
Having said that, it's more likely a hardware issue (i.e. dead to dying Battery, failing Power cable, broken CPU fan, etc.) instead of a virus infection. Make sure to check the first two steps to get you closer to properly troubleshooting your issue.

Think it is over heating

Ours kept stopping as it overheated - soluion was to get a chap platform to elevate the laptop which allowed it to 'breathe' a bit better and hasn't stopped since. We orginally had it directly on the desk so the air wasn't circulating

Has the fan been replaced? If not then the laptop will power itself off to protect from overheating. The fan is like a switch in the loop. Like old Xmas lights. One not working then none will work.

a power surge could have caused this problem, as you so rightly assumed. motherboards-cpus et,c. are prone to fail or malfunction. even with static electricity.
it could also be a sign that, the tft ( screen ) has faults or the cfl (tube) or inverter have suffered damage.

Zd8000 LCD no display

Sounds like your display went out to me. You may be able to replace it yourself, depending on your skill level/experience with electronic repairs. At any rate you'll need to find a reasonably priced replacement screen. I usually find New and Used ones on ebay and laptops for parts there and other internet classifieds and auction sites. You could also get a replacement through HP, but at an inflated price I'm sure. Since yours went out and it's not a simple repair, I would only consider a new replacement screen and after figuring the cost, resources that your laptop has compared to a new replacement, and time involved, only then would I determine whether it's worth repairing or not?

On the other hand, you could check the ribbon cable that connects the display to your Graphics card on the Board and re seat it to see if that cable has come loose causing your very dim display. My experience would lead me to expect the LCD to have run it's course though.

Happy tinkering and Good luck.
