My HP Pavilion Entertainment PC : P/N: KN831UA#ABA (dv6815nr) started turning itself off abruptly and at random.
Now pressing the power button causes it to try and start, but after 5 to 20 seconds it turns off.
I recall that it got very hot a few times since I purchased it in April 2008.
I've read the boards and tried all the stuff they recommend such as removing the battery, hard reset, remove the CR2032 3Vdc RTC battery for an hour then replaced with a new RTC battery, put it in the garage overnight after removing the HDD so it would chill down to about 30 degrees F and brought it in the next morning and quickly installed the HDD and powered on with no change in symptoms. So it can't be an overheat problem.
All the lights and fan come on like normal and then after a few moments, PC goes completely dead. It shuts off like you have the battery removed and are powering it on AC and then pull the plug out of the wall outlet.
I'll continue to search the Internet for clues, tips, hints, etc for quite sometime as I don't want to give up on this PC, I really like it and have used it a lot. I know if I can fix this it still has many miles left on it.
The thing I've noticed most reading these boards is that there are a significant number of laptops within this model category with the same exact issues and HP has yet to do anything about it. Maybe they will if more reports keep coming in.
It is quite obvious that this many laptops of the same model with the same problem is the result of something they all have in common right from the factory, whether it's design, a bad lot of components, etc.
HP really needs to take a step in the right direction by solving what's causing this because once they do they will see that they need to have a recall for these models. This goes way beyond a few random identical failures.
HP: if you're listening....please help.

I agree , I have contacted them on several occasaions and all they say is to send it in , which will end up costing me more than the laptop cost me. if something doesn't happen soon i am going to another manufactor because all i did up to this point was recommend hp and buy hp

I was just recently battling the same problem. It would boot up and run Vista for about 10 min then shut down and not power back on for about 15 min.
The answer is that the CPU is overheating. I installed a program called "Speccy" that monitors the tempurature of the HDD and the CPU. THe CPU would go from a nice 47C up to 103C then the laptop would shut down like someone pulled the plug.
I then tried opening the laptop and applying new thermal paste. No improvement. Finally I started trying the different power settings(click on the battery icon on the taskbar) and found the "power saver" setting was the only one that worked. The Windows Vista default was "balanced" and that runs too hot.
Then I compared the advanced settings for "balanced" and "power saver" and saw that the CPU power settings for power saver were for 50% on both battery and on AC power.
I saw the balanced settings were at 100% for the CPU max power managment. I set it to 80% max... it shut down again. I set the processor maximum to 75%. It kept running! In fact I installed 99 windows updates over 4 hrs without any shut down problems.
So... go into the power options ---> chnage plan settings ---> change advanced power settings----> then adjust the processor maximum state to 75% (or lower).
Hope this helps you out and like I said I have been struggling with this for a month. I even installed Windows 7 and found it shuts the laptop down faster. Now I am back to Vista Business and all is good.

It's a hardware problem with the system board. A computer tech at Office Depot said he heard about this problem with these laptops and that a chip made by Nvidia was made with too thin of a heatsink on it and consequently could get too hot and render it useless.
In consideration of the cost to replace the system board, I purchased a new HP laptop. It's a G62-340US that I paid $350.00 for on sale. I'm going to take the HDD from the dv6815nr and put it in an enclosure and use it as an external HDD.
Good luck!

Hi,
My laptop will not boot. So, how do I remove the HDD? or where are some schematics on the motherboard/laptop?

you can remove the hard drive from underneith the laptop , it has two screws on the cover and is a sata srive so it pulls right out

No it can't because it's an integral part of the chip.

that's great i have bought hp's wether new or used all the time along with my current hd widescreen monitor , i can't beleive they would not fix this for free because to send it to them and get it to fixed will cost more than the laptop is worth now.
I can't afford another laptop , i plan on going back to either toshiba or maybe a dell , i never had a problem with their laptops

it's ovious that hp doesn't read these threads and won't even acknowledge ths issue when after reading several artciles on the internet it seems to be that alot of users are affected by this issue with it overheating. It's sad in a way, but it is what it is , i'm looking into a new laptop now , any ideas on one that would be equevelent to this one or at least a far better?
I've been looking at some dell laptops and i never had a issue with them , unless i caused it that is ..lol
Ideas????? anyone..??????

I just posted my similar problem on another thread. I'm so angry with HP right now! This morning my laptop shut itself down and won't reboot - I'm lost in an endless cycle of the machine trying to reboot itself but shutting down again after 5-10 seconds. I thought it was very odd that I wasn't initiating the reboot cycle - doing that on it own and wouldn't stop until I pulled the battery.
I've tried to contact HP via online chat but the site won't open. Of course I could call them for a price. I went ahead and purchased the restore disks and will give that a try, but it sounds like that may have been a waste of $25 if my problem relates to an overheating chip. I think I'll try the garage trick tonight!
This is my first HP. I've had great experiences with Dell in the past (three laptops and two desk tops). I thought I was upgrading with an HP purchase - wrong! Funny thing is, I almost bought a Toshiba and my husband talked me out of it due to perceived quality control issues. Best laid plans...
