Hi Everyone,

I recently brought a HP Pavillion DV2500 of a friend for a really good price because of a hardware fault, the problem was with the screen, when powered on there would be multiple images of what should fill 1 screen, instead there were 6 mirror images of the boot, and xp screens, it was a hardware fault because it would happen even at post, sometimes the graphics were so messed up it was unreadable.

I dissasembled the laptop and re-assembled it ensuring all cables were connected properly and violla, it did the trick, the screen was once again functional.

But now I am plagued by serious overheating, I have tested this with a number of programs and its a problem that I think will claim the life of the laptop in a matter of weeks.

First problem I noticed was when the laptop would randomly just turn off, no blue screen of death, no warnings, nothing, it would all of a sudden turn itself off instantly with no shutdown process, which is typical of a power supply or over heating issue, since the battery is new and the power supply is faultless, I deduced it was overheating, and after checking the temperatures I was right,

The CPU core 1 and 2 were both hitting the mid 90's at peak 93c was common, and the GPU was running at a constant 85-90c, only when i reduced the laptops power profile to minimal performance did the GPU go down to 75c.

The laptop is suspended with a 5mm gap below it, and half the laptop suspended in mid air, so no airways are blocked, yet the heat coming from the laptop is ridiculous, it gets so hot you can smell that hot metal smell from the exhaust outlet. I know this is not right since I can burn my hand on the bottom of the laptop if its been busy for more then 2-3 minutes with an application.

My concern is the absolute crap idea that HP had to use a thermal sticky pad to remove heat from the top side of the GPU rather then using a copper cooling system like most decent laptops would do, instead HP have once again made a huge cockup and as such have discontinued the HP pavillion series!

What would be a good starting point to try and reduce these temperatures? I have some silicon paste from a northbridge cooling kit left over from my PC build, would it be worthwhile using this?

Im not being funny but I see alot of people talking about cooling pads and mats and things, but it makes no sense, since a laptop is a portable pc thus should always work on the move, rather then needing other peripherals to cool it?

Also, someone please tell me why this 2007-2008 laptop still only uses 1 fan? Im not being funny, but with a dual core T5460 Intel processor (i think) it would have made sense to give both the CPU and GPU independant cooling fans rather then trying to gain maximum cooling from 1 fan?????

Anyone have any ideas? I know that this is potentially damaging to the laptop since the screen will sometimes randomly flicker, which I know is a sign of malfunctioning hardware and not a driver related issue?

Thanks
Daniel
 
Honestly, it seems that something is missing a heatsink. You mentioned there just being a sticky pad instead of a heatsink right? That is a problem right there.

I have a dv5t and it only has one fan as well. This thing runs fast and can get a tad toasty while gaming. But, really that's why I bought a cooling pad for gaming. Otherwise, it is very cool to me. I know you have a different model too.

It sounds like the cpu would be downclocking if it got that hot, unless there is a faulty sensor and the thing will eventually fry. usually, laptop parts are made to withstand higher temperatures, but 90C is very hot. Not even my gpu gets that warm and i have a dedicated one

I really do not know what else to tell you. Something is not right in that system....talk about toasting your pants!
 
while fixing the inside, did you remove the haetsinks/cooling products? it may have disrupted the thermal transfer from the chip to the heatsink and could cause overheating, although i kinda doubt that the case.

when it is running fast, does the fan speed up? if the fan is not spinning fast enough then that could also cause overheating.
 
Agreed, the stickers at the bottom of the laptop have darkened from heat exposure, I have just turned it off for an hour, booted it up, the CPU (0) AND (1) cores both tick over at about 47c when Idling, but then again I have changed the laptops performance settings to Power Saving so the processors are running slower, but the GPU is still at 60C even when running a plain screen and no video utilisation?

I ripped the thing apart and the GPU is on the top side of the mobo, which shocked me, it uses a sticky pad connected to the metal shield which the keypad sits on to dissipate heat, there doesnt seem to be anything missing because there are no screws, mounts or clips, its just sat on its own, Im not kidding you but HP really do have issues with their builds, they focus too much on looks, and thats no joke, the laptop is a looker with trans reflective screen, piano finish, stylish button arrangement etc, but when it comes to practicalities, the build is poor.

The intake port is tiny in comparison with exhaust outlet, yet the bottom of the laptop is deprived of intakes in the right places.

I was always a fan of HP but in the recent years they have declined, I have seen nothing but complaints about the Pavillion DV2000 series, mines the 2500 with dual core 1.66ghz intel, 2gb ram etc.

People have had so many faults with them which is a shame since they look nice, have lots of features, and when they work properly they are a dream, sadly I think HP need to seriously reconsider their development patterns
 
No, I made sure all surfaces met as I know the smallest gap can cause a complete failiure in heat dissipation.

Should a GPU run in the high 80's or am I asking for trouble? I dont see why I should have to run it in power saving mode to stop it from turning itself off?
 
Hey Daniel

I have just experienced the exact same problem with my dv2500. It began randomly turning itself off about two months ago and now I just get the six mirror images on my screen as well. Have you been able to solve your problem yet?

I have temporarily solved the problem, although it works now and again it still plays up. Sadly this is because of a damaged GPU and it will always do this for the rest of the laptops life. What happens is that the GPU itself begins malfunctioning and the overheating actually damages the chip and many of its ability to use shared memory since its the nVidia N8M chip series.

What I found was that when the chip reached 85C + it begun to cause screen flickering and random characters to display, after a few minutes it would then switch off, and upon switching it back on, the screen would be messed up with 6 images.

You can fix the problem to a degree but it means opening the laptop up, you need to get onto the top side of the motherboard, and apply thermal paste and a large thermal sticky pad across the GPU, this will only work for a small while but it will enable you to use the laptop and recover data.

Another thing you can do, is when you get back into windows, drop the performance on the power saving to Maximum battery, this reduces the load on the GPU meaning it will run cooler.

Sorry to say though that the DV2500 is a joke of a laptop, HP are a joke and I am not impressed with the issues that surround these laptops. These laptops run incredibly hot, and it only takes a few minutes at 90C plus to begin causing hardware malfunctions.

Let me know how you get on
 
hello everyone

I am talking to hp over the issue.I am trying to convince them that the problem is in the design of the product.If they are convinced ,then they would start an advisory for this series.An advisory is something by which hp replaces the failed product or the affected component of the product with a new one free of cost even after the finish of expiry.To convince them that the problem is in the design,I need serial numbers of the laptops having the same problem. So,please post your serial numbers and also the specific model number(only if you have six multiple images problem).

Regards
Rohith Mohan
 



Did you get any reply from HP???
 
I'm having the same problem on my hpdv2500. It only seems to happen when it runs hot (and it runs very hot) -- just started last week and the computer is not 1.5 yrs old. Any word from HP? They didn't seem to mention the issue during a "help chat". Kinda worries me though since my wife just bought a newer HP....! If you are looking for serial numbers, could you post your email for us to send it to?

I have a similar problem and HP Support immediately escalated my case. However the case manager is offering me a out of warranty repair for which i have to pay. They are not explaining why Tech Support escalated the case. I think they know there is something wrong but do not want to admit it. Laptop is now posting to scrambled screen and is unusable. It is 1.5yrs although issue began 6 months ago. I am pursuing this right the way up to the CEO. It's a design issue and I am wondering if this applies to the NVidia CHipset. They are also not responding to the question if there are aware of over heating GPU issues with NVidia Chipset. Instead they tell me there are not aware of any service advisorie's relating to my serial number. It stinks and something's up. It cannot overheat to the point where your hand looks red out of normal usage.
 
Hi, the same thing is happening to me. My PC heats up and the image goes pink and freezes and puff it dies. I let is cool down and then try again. Any news fro HP on whether it's a manufacturers problem . I have checked the recall battery email and it doesnt seem to be the battery, but it must be something ??

Any more news or update
 
I had a dv8000t that I just sold recently that had similar problems but I fixed them. Undervolt the cpu and copper mod the gpu if you can. Good thermal paste will help too.
 
I am disappointed because the three notebooks, all HP pavillions that I purchased have not performed and lasted as they should have being Hewlett Packard products which in my past experiences have been very reliable and of a high standard of quality. Each notebook has had continuous over heating issues whereby the fan would work so hard and the laptop itself would get so hot that the notebook would shut itself down. In the past week my partners laptop had been exhibiting a purple and green fuzzy screen, then freezing. It is now at the point where the screen does not display though the computer itself is on. Now just a week afterwards my notebook (2) has done precisely the same thing and I can no longer use it. This proves very inconvenient on my behalf as I use my notebook everyday for work purposes, as do my partner and my sister. Notebook 1 has had the same overheating issues, but is yet to lose its display. I do anticipate the same issue will transpire with Notebook 1, it seems it is only a matter of time. In my opinion this product is not of satisfactory quality as laid down by the law.

I appreciate that the three notebooks are just out of their 1 year warranty and would accept the issue at hand if it was only the one notebook. However, the recurring issue in all three notebooks in the same time period tells me that the glitch is a manufacturing matter and perhaps a little suspicious or convenient with it's timing and I believe Hewlett Packard should be held accountable.

I have heard that there was an extended warranty put out by the manufacturer on these laptops in all countries except for Australia and Canada.

and lastly:

read and heed, this is GG moment for HP and others that uses the cheaper/less well designed nvidia stuff.

Nvidia may be going if this blows out of hand and they get slapped from Dell, HP, Acer, Apple, and every other major OEM that uses their parts.
 
O and btw, you can disrupte that the inquirer is a bunch of crazy guys with deep connections that is willing to publishing any little wind of tabloid as facts, but with nvidia filing their nice 8k forums in the US and stating this fact, chances are it is true, or mostly true.
 



dude
I am using HP Pavilion dv2550ee laptop, I have the same 6 screens problem (six multiple images problem).
My "SERIAL NUMBER-2CE73226QD and PRODUCT NUMBER-GS609EA"
 
My HP DV2500t is much worse! It has thousands bricks in the screen but windows working fine since I heard the start of the windows. It's purely a video card problem.

I have let this laptop sitting over there for almost half a year. I am thinking to lead a class sue against HP, anybody interested ?
 



hey, im using hp pavilion hp 2500 series, could you get back to me whether hp has any criteria since it is so obvious that the problems are caused by the flaw in the design. ive heard about hp extended warranty but my laptop is already around 2years old, i wonder if i can claim the repair, since it is so unfair for us as customers. hope to hear from you soon. :)

regards,
rosemary
 
hey btw my problem is the six screen thingy also, i sent to a shop and they added the heatsink but the problem still exists on and off. it doesnt help much. anyone has better idea what to do?
 
I have the identical '6 screen' problem in my dv2500 series notebook with serial no. 2CE7493532. HP sucks. Make sure you spread the word NOT to buy HP products
 
HI
I have 6 screen bug during bios load and after on hp dv2750 - this must be all hp dv2000 problem
First six mirror images only shows during ubuntu shutdowns now they are all time?
any solution to this problem ?
is this main board or lcd cable ?
Thanks.

HP really sucks.
