Laptop turns on off on off on off--wont stop!!

[pjmerfie49]

Kodi,

I have gotten my computer to partially boot using the method you described. However a problem occurs when windows is loading. Half way though loading the computer crashes and it returns to the On-Off cycle again. Does this sound like a BIOS problem or something different. Do you have any solution?

Thanks

Patrick

Ok I just figured out how to get mine to work. You take out the battery and unplug ac cord. Then you take out the Hard Drive and take out the SATA Connector that goes into the hard drive. Be careful on pulling it out. You have to pull both sides at the same time. Then try to clean the pins on the hard drive connection and the SATA Connector. In my case the connectors were loose. Then put the SATA Connector back on the hard drive an reinstall the hard drive. Then plug everything in and hit the power button. It should turn on. This happened to me twice but the second time is when I pulled the SATA Connector off. The first time it happened I took the hard drive out and put it back in. Then I did a dianostics report and said to replace my Hard Drive but it has been working good since so it might be getting a false reading. Good Luck.

Follow up on my Post.

It works temporarily. If the laptop cools off, will go back to shutting on and off. So I let the pc run for about 2 hours and let the hard drive heat up and do the same steps I posted prior to this one. The step for letting the hard drive to heat up is as follows

Hit the power button. it will go into on and off mode. when it turns on again hit esc button and the fan will go on for a few seconds and shut off but the led buttons stay lit. Keep in that mode for about 3 hours then unplug ac adapter and take out hard drive and take out sata connector. Then plug connector back in and put hard drive back and plug back in and hit power button. This proceeder is for pcs with bad hard drives. I can't gaurentee it will work for everybody but its worth a shot.

The problem seems to be showing up now in the DV9700.

Problem is, HP does not have this model on their list of Recalls. When I asked how I can add mine to the "Count", of course this was unknown.

The good news is: HP finally agreed that it was a hardware problem, that neither the $49.95 nor the $99.95 phone support contracts would be able to fix!

They did recommend pulling Memory, HDD, Optical Drive and seeing if it would boot to  BIOS at least. If so, then start adding the components back to see which is really bad.

(Of course, if it does not get to BIOS this way, then the MB is damaged.)

My guess: overheating as fried something, and I am worried about going forward with this same PC (and manufacturer).

Hi, everyone. I have the same problem, on,off,on,off.

HP Pavillion 6700

Bought  from Bestbuy in May 2008.

The product design had defect, but they don't be responsible for this issue.

My new laptop will surely be NOT HP.

This is exactly what HP "Escalated" support finally told me to do.

In my case, when problem persisted, my Computer Tech shop said the problem was on the motherboard.

Costs: $250 if MB could be repaired, $550 if MB needed to be replaced.

Conclusion: spent my $550 on a new DELL

(All data on the HD was just fine: using a USB-connected HD "Toaster", just moved it all to the new PC.)

Hello there,

I have the same problem on my dv9000. it was working fine one minute then the screen started going

weird. so i turned it off and it keeps turning on and off and on and off.

I am from the UK and I bought this whilst working in the States in may 2008. i paid by debit card so I have no warranty, i got it from best buy in Colorado.

I'd like to add that ive upgraded to windows 7 and it has been working fine for about a month since. I have tried most of the solutions on this forum except for taking out the battery on the mobo. Which i will try.

if anyone could give me an idea of what to do i would be grateful as I have 1000's of photographs that I dont want to lose.

Thanks

I've probably posted this here before but there is a trick that I have used on my dv9201 to get around the same problem. No guarantee that it will work for you but worth a try. Hold the delete key down while you boot the machine. If it works, the HP logo will come up on the screen. It may take up to 5 or 6 tries. If it doesn't work almost immediately, press the power button and hold it until the machine shuts down (don't wait for it to re-boot on its own). Start it again holding down the delete key and try again. I have had trouble making this work when the battery is low so if that is the case I usually let it charge for a while first. I also had a problem with the seating of the hard drive and it wouldn't work in some cases unless I reseated the hard drive or swapped another one in. I can't believe that this would only work for me and no one else. I'd be interested to hear back if anyone else is successful in making this work. Chris
