I have found a thread with a similar problem...
http://www.daniweb.com/forums/thread15877.html
The short of it says that they were/are having a similar issue at power on. Thier problems started with a bad BIOS update from HP.
I know none of the posts in this thread mention a BIOS flash but the similarities shouldn't be overlooked.
Since the computer will not POST then could our problems be a corrupt /malfunctioning BIOS?
I will wait to see what Scanyman reports back with. They may replace his MoBo without diagnosing the source of the problem.
A new BIOS chip should be cheaper than a new MoBo for those of us who are out of warranty.

Quick update, spoke to the local HP center today on progress and confirmed they think its a processor problem and are awaiting part to be shipped from HP. They couldnt however provide any timescales as to how long this will take.

To be continued .....

I am having the same exact problem with a Compaq Presario V6030 laptop. I have tried everything in this thread and it hasn't started up. I had this problem before and I took out the battery and left it unplugged overnight and it worked. I tried that this time, but it will not start, even after remaining unpowered for almost 18 hours straight. The problem occurs when I place the computer on standby mode and it automatically hibernates from standby after being unplugged for 30 min., which is the default setting Windows power managment has on my computer.

I believe the problem may be that the computer is unable to come out of hibernation mode when it hibernates while in standby. Does anyone else remember if their laptop was in standby and on battery power just before it stopped turning on?

My HP Pavilion dv6000 had no problems. Yesterday, I got an email from HP with this link http://h10025.www1.hp.com/ewfrf/wc/g...en&lc=en&cc=us warning of a critical update and to contact them at a special number if I have any of a number of listed problems-- one of which being the computer won't come on. Last night, I checked email with no problem, closed the computer while I went to do dishes, thought I heard a strange click/pop, and, when I came back to the computer, it wouldn't come on. When I hit the on button or the quickplay button, the lights flash briefly but nothing happens, it doesn't even try to start. My serial number falls within the range. Whatever is going on, HP knows what it is. It's highly suspect that it died the same day I got the email about possible problems. Complain, post, raise a stink.

OMG! Thank you sweetie pie for the link! Tomorrow I am calling them!
Here is a link to HP site with international numbers, in case someone needs it!

Mine does fall in the model and seral number range!

Good luck everyone!

I have sent my lappie to HP, and now I get an email that tells me that my "enhanced" 1 year warranty is void, since the unit has been opened.

Can you imagine THAT? Very convinient, isnt it? They sell me a #$%^ed up product and now they tell me I have to pay if I want it fixed. Unbelievable.

Anyone with any results from HP?

I sent mine in last Monday and I got it back on Thursday that same week. The computer works now, and my wireless card started working again. Haven't had any problems so far, but I bought a 1-year warranty just in case (It's cheaper than buying a new laptop, so I figured why not).

Hi everybody,

Quick update as Ive just received my laptop back from HP.

repaired under warranty, took just over 4 weeks, seems ok now. The service sheet shows replacement of System Board and CPU. I had been checking in and at one point only one component had been replaced and they then had to order up the other, not sure which was tried first.

My laptop didnt fit the serial number range or fault list on the recall notice.

Mine had flashing leds for a second or to with momentary access of HD and CD drives, fan runing for a second or so.

I think mione was a hibernation issue and I am sure this is the one of the problems with the DV ranges from the dozens of posts on the net.

Good luck in sorting yours.

I am glad you guys have your l lappies sorted!

HP is still messing me around, feeding me promises. Oh well will wreite an update when i get any clarity.

dammmm. It just happened to me... unfortunately I bought it at the USA and now I am in Colombia, "obviously" there is no warranty for it here.

Damm.
If anyone knows how to fix it please post it. I won't pay the full HP price beacuse of one of their errors.
