Question about HP Pavilion zd8000 Notebook

Won't power up

My laptop won't power up.  It tries to power up, then stops and makes a hiccup noise.  It then powers down and tries to power up again.  This happens over and over again.  The only way to stop this is by unplugging it and taking out the battery.  Help!

    No beeps, just the sad hiccup sound.  I don't get a display or anything.  It sounds mechanical.

    The first few times I had this problem (constant reboot cycle that could only be stopped by holding down the power button) I could get it to eventualy boot by forcing it to power down, wait about 2 min and boot up. When it is in the constant reboot cycle it does not even get to a point where it is sending a signal to the monitor. If it ever got that far it would boot. After a few days this would no longer work and I got mad and just put it away for about a month. Got it back out and turned it on and it booted. I remembered that the only thing that had changed was that I had put on XP SP3 just befor I started having the problem. The first thing I did was remove SP3. After that was complete I had to reboot. Guess what....friggin reboot cycle again. Over the next week I'd try to boot it up about every other day. Nothing. Constant reboot (only takes about 5 seconds). No signal to the monitor. No chance to enter bios. Will not boot to bootable CD. I'm guessing it's a bad hard drive or bab memory. Any suggestions? Please help. It's a very nice lap top WHEN IT BOOTS!

I have an HP Laptop zd7020us and I had problems with it booting up. When I turned it on, it would run for about 15 minutes and then freeze. CTL-ALT-DEL would not work, so I had to power down by holding the power button for 4 seconds. After troubleshooting for quite some time, I finally found the problem. I had two sticks of ram and after trying each stick individually, I am running with only one stick. The other one was faulty.

Other indications that this might be your problem: After it runs for a short time, it will not allow you to boot up again. All the power lights come on, the fan kicks on, and you can use the CD/DVD drive, however, it doesn't POST.

This is an indication of faulty RAM.

Hope this helps someone and stops you from buying a motherboard unnecessarily.

    This error can be caused by one or more of the below possibilities.

    Floppy or CD that is not bootable is cur...
    BIOS or CMOS setup is not setup properly...
    Hard disk drive does not have bootable f...
    The hard disk drive is bad or not connec...
    Solution: Floppy or CD that is not bootable is currently in the computer Verify that no floppy diskette or CD is currently in the computer. If a diskette or CD is in the computer that is not bootable your computer may attempt to boot from that diskette or CD causing this error message.
    BIOS is not setup properly Additional information and help with getting into BIOS or CMOS setup can be found on

    Verify that your hard disk drive is setup and detected properly in BIOS. You're computer should list a hard disk drive installed either under the main page or the drives page in BIOS. If BIOS indicates the drive is not installed or not detected skip to Hard Disk drive is bad or not connected ....
    Verify the boot options are properly set in BIOS, almost all BIOS setups should contain options specifying how your computer boots. For example, most computers should have their boot options setup similar to the below example.

     - Floppy drive
     - CD drive
     - Hard drive
    Rest your BIOS to default values. Many BIOS will enable users to reset the values to the default settings. If you've tried the above options without success try resetting the BIOS.
    Hard disk drive does not have bootable files on it It is possible that or another bootable file may be missing from the hard disk drive. Follow the below steps to possible resolve your issue.
    Windows 95, Windows 98, and Windows ME users

    Boot from a bootable floppy diskette.
    At the A:\> type fdisk
    If you receive a message no fixed disk present, read Hard Disk drive is bad or not connected ....
    If you are able to get into fdisk, choose option 4 to display the partition information. In the partition information, if the System is listed as FAT16 or FAT32 then continue to step 5. If you have a message indicating no partitions defined, no information is on your hard disk drive and you will need to create a new partition. See our fdisk page for additional information.
    If you see FAT16 or FAT32 in fdisk press the ESC key until back at the A:\>
    Once at the A:\> type, sys c: (only do this command if you are using the same operating system that this diskette was created on).
    This should return a message 'System Transferred', if you receive bad command or file name and have verified you have typed the command properly, you will need to obtain a bootable diskette with the file on it.
    If system was transferred successfully, reboot the computer and issue should be resolved.
    Windows 2000 and Windows XP users

    Boot from either your ERD, your bootable Windows CD, or your bootable restore CD.
    Once boot attempt to repair Windows. If you're able to repair Windows remove the disks and reboot the computer.
    All users
    If your operating system is not listed above or the above steps did not resolve your issue you can also try erasing the hard disk drive and starting over.The hard disk drive is bad or not connected properly
    If you have attempted all above suggestions and you are still encountering the same issues, verify the connections are properly connected to the computer if the hard drive was recently installed or the computer was moved.

    Unfortunately, if all connections are setup properly and all the above recommendations have been attempted, it is likely that the hard disk drive is bad and it will need to be replaced.

    check power suplay and ram???Let me know if u get help???

My compaq CQ 61-420 US notebook won't turn on It was on and we left the room for a few minutes and came back in and it was off and won't come back on the 3 lights in the bottum left flash 3 times...

Greetings! Whenever you're dealing with a laptop computer that does not power up the first thing you want to do is disconnect the AC adapter from the laptop.The next step is to remove the battery from the laptop. Then reinsert the battery and reconnect the AC adapter. Press the power switch at this point and see if the laptop will power up normally.

Laptops are also prone to overheating. If the laptop powers up after it has cooled down and then fails again you may be dealing with an overheating issue. Try taking a standard can of compressed air and blowing out the ducts that supply fair to the cooling fan, as well as blowing off any "dust bunnies" or visible debris that have accumulated on the cooling fan itself.

Also make sure that the laptop is not sitting in an orientation that impedes the airflow to the cooling fan.

I have the power cord plugged in all time when using it because battery no good. I then plug in the mouse and things are fine. If i pull the power cord too far or wrong way it comes unplugged from laptop...

Well, if you have a faulty battery and the your power source is lost, the USB obviously won't work either. Sometimes when there's a sudden loss of power, the computer's devices won't function properly. A hiccup in the programming will mess them up. I would suggest getting a new battery. I hope this helps.

Dell Studio 1737's power pack makes a shrieking, humming noise

I would stop using the adapter immediately. It could be about to blow. When one of these blows, you can get smoke, sparks and fire. You don't want that to happen when you are not around. Further you don't want to have a voltage spike from the adapter to *********** board. You can buy a new adapter at Walmart or whereever. Just be sure that it supports Dell computers. Dell uses a third pin frequently. Check the voltage and amperage of your current adapter. You should see something like 19V and 3 Amps. Make sure that your replacement adapter works within those rages.

You can also buy an exact match from Dell or ebay.

Expect a good Universal adapter that you buy at Walmart to be in the range of 50-100.

The good thing about a universal adapter is that you can use it on another notebook later.

Power light is on, and nothing happens.

The RAM may have been "jammed up" when it was put to sleep. You said you powered down completely and then started up again. How long did you leave it before turning it back on? Try it again, but this time, unplug the adapter from it and also take out the battery so there is absolutly no power going to it. Leave it like that for about 5/10 minutes and then try it again.

Hopefully that will help you out
