HP Power-On Failure

Hewlett packard pavilion / Dv9700 (dv9819wm)
April 11, 2010 at 15:48:24
Specs: Windows Vista Home Premuim, AMD Turion 64/2Gb RAM
I purchased a 17" HP laptop in 2008. I had an issue with the screen (at certain points in the lid's rotation the screen would disconnect) and the DVD drive not being recognized. HP fixed these issues under warranty.

Now I'm having a new problem. When I hit the power button on my laptop all the lights on the QuickPlay bar come on along with the wireless adapter light and the power light, just like a normal startup. Then the fan comes on an the DVD drive spins up, again like a normal startup. At this point, the hard drive make a little metallic pinging noise (just once) and the laptop looses all power. 5-6 seconds will pass and then it tries to pwer up again with the same sequence of events, ending in a total shutdown. This cycle will continue indefinitely, and the only way to make it stop is to remove the battery and unplug the charging cable. The screen stays black and powered off the entire time.

Any ideas for fixing my computer?

Do you know how to remove the HDD? Take it out temporarily & try to power up the system. Do you still have the same problem or does the system stay powered on?

I tried pulling the hard drive and powering up the computer. The same cycle occurred, but without the metallic ping. The lights come on, the fan starts, the DVD drive turns over and then the whole computer turns itself off.

I contacted HP support (kind of a misnomer, they are not supportive at all) and they told me to remove the battery and unplug the power cable, then hold down the power button for 15 seconds. This had no effect on the issue.

Sounds like the CPU is overheating. Blow some air thru the cooling vents, then see what happens. If you don't have a can of compressed air or a mini air compressor you can use, just put your mouth up to it & blow as hard as you can.

The computer had been left off for a significant amount of time before I tried to start it up. It was completely cool and was not on long enough to develop any internal heat. How long would it take the CPU to develop enough heat to cause a problem?

I have this same issue and looking for answer also. My dv9700 fan was running fast and the unit seemed to be running hotter.. So i fully dissembled it to clean the fan and get the funk outa there.. I'm glad i did cause there was alot of funk in there that compressed air wouldn't have removed.. But as soon as i reassembled and fired it up. This same issue started to happen. Disassembled again and double checked all the ribbons,ram,harddrive. ect.. and everything i could think of.. Same issue.

I see no blinking lights to check for codes either. I'm Stumped at the moment.

I had the unit taken to a local repair shop to check out the issue. HP Support was absolutely no help, big surprise there.

The guys at this place kept it for a week and then called me back. They had found the problem, and it is apparently one that HP knows about. The graphics card runs hot and the internals of the 9819 are designed in a way that the fan does not adequately cool the motherboard and graphics card. The internals heat to unacceptable levels and eventually melts connections on the motherboard. At this point the motherboard is toast, and the shop I took it to said they don't even stock the brand of motherboard. The repair was going to cost a lot more than the actual computer was worth, what with a new board and a bunch of new internals.

I took the $50 they offered me for the parts that weren't complete crap, removed the hard drive to use as an external HDD with an enclosure and bought an ASUS EEE netbook.

I researched the issue further and discovered that HP enacted an Extended Service Warranty for some of their DV series laptops. They have a problem with the BIOS that causes the fan to not function properly. This causes intense overheating issues. Despite this being the exact problem I encountered with my laptop, my machine is not included in the Extended Service Plan because its number is not on the list held by customer service.

This is the last HP product I'm going to buy. I absolutely loved the DV9819, but the customer service experience I had with HP has turned me off of their product.
