Re: HP Pavilion dv8000 suddenly crashes

Same thing has recently begun happening to me perhaps the temperature sensor is out of whack. has the problem gotten worse? it's like some disgruntled engineer planted a bomb somewhere in the bios

 

Re: HP Pavilion dv8000 suddenly crashes

Actually, it fluctuates. Like now it's been on for two days continuously, but the other day it crashed on me three times. It crashes when I run a Norton virus scan, too. I even bought one of those under-the-laptop heat detractor fans. Still crashes. Are we effed or what?

 

Re: HP Pavilion dv8000 suddenly crashes

ugh.. Dood... i hope not. we could start some kind of support group for owners of Dv8000's that have passed away... and talk about all the... good times

 

Re: HP Pavilion dv8000 suddenly crashes

I work at a PC repair shop. This laptop came in a Pavilion dv8000 and its just a piece of crap. :upset:

I reinstalled windows and even during the windows installation it was running slow. Its taking 20 minutes now to find the drivers off the recovery cds. :sigh:

any ideas of why its slow? i tried swapping memory.

 

Re: HP Pavilion dv8000 suddenly crashes

Unplanned shutdowns can be caused sometimes by over heating. Try using a cooling pad or use a book or a marker (around 1 inch high) and place it under the laptop (specifically on the side where the LCD is). Make sure the vents at the bottom are not covered or blocked by anything.

Refrain from using the laptops completely flat on a table as this will block the air flow if you have vents at the bottom. Also on floors with carpet or in bed as these usually block the cooling vents. If on the table make sure you elevate the LCD end of the laptop by placing something like I stated above.

If using a cooling pad or by simply elevating the cooling vents from the table or the floor still give you shutdowns and a noticeable hot exhaust from the vents, I suggest you have the insides cleaned (compressed air thru the fins/heatsink or have it opened by a repair shop or by yourself if you know what to do).

Thanks so much for the help, fixmypc. My detractor thingy with its cooling fans has pretty much stopped helping and the laptop crashes every half hour. I just opened one of the panels (the only one I dared) and, with it open, I also blew compressed air into the fan. I will be sure now to reset it on my desk (it was sitting flat on the table) and prop it up in a way that the fan isn't blocked. I have a sneaking suspicion that it needs to be opened and cleaned, considering all the places I've traveled with it.

Thanks again!

 

Re: HP Pavilion dv8000 suddenly crashes

Careful when you pull it apart to clean it. I installed a game I wasn't sure would run on the dv8000 and sure enough the thing crashed when the game was starting. Without much ado I assumed overheating and opened the whole thing up to clean it. No problems there or on assembly, but now the machine does the crash thing as soon as the fan starts blowing hard, so it's a bit intermittent how much I can get done before it randomly shuts off. If it were a desktop I'd assume the video card/processor was cooked, but video's integrated. The processor is not really upgradeable. I may be looking for another laptop (that I can't afford right now). Mine, too, is about 2 years old. time bomb

Anyone have any real expertise on this issue?

Xonikz, I wondered the same thing about my video card, but I was planning to take it somewhere for that evaluation, since I know squat. Good to know that that's probably not the issue. I can say, though, that since I blasted the fan with compressed air, it's behaving better. I mean, it could be the heat sink, but how much is that going to cost to replace? Is it even replaceable? I might as a last ditch effort call a guy who does computer repair for a friend of mine to come over and take it apart to clean out any dust bunnies. But like you said, putting it back together might cause problems.

In the mean time, I'm saving money, anticipating that I'll need another machine within the next three months, and I'm turning off the machine during the day and at night when I go to bed to keep it as cool as possible (still not sure how much the cooling thing underneath is helping).

 

Re: HP Pavilion dv8000 suddenly crashes

The heatsink is very replaceable, so is the processor. I'm now working on mine, but it only works on my lap and not on a desk, tell me that's not weird.

Fascinating. Thanks Dai and Xonikz!

I'm wondering, too, now about what Mofotronimus said about the thermostat. Freak ***, man. Who do you guys trust to deal with these things? Friends? Yourselves? I'm paranoid about giving my machine to someone to fix it.

 

Re: HP Pavilion dv8000 suddenly crashes

I already had the manual and some cpu paste. This issue is something unexplainable in standard surface assembly.
:sigh:

 

Re: HP Pavilion dv8000 suddenly crashes

I've worked it out and found that this issue is not heat related. The temperature gauge that I temporarily installed in the machine this time around (3rd disassembly) was reading well within a manageable range and the fan didn't even kick on, however the system crashed upon transfer of some large files to backup hard drive. As that process doesn't engage high GPU usage, it's likely that it's not graphics card processor related either. I have a running suspicion that the crash is somehow related to the amount of power being drawn at any given time. If the hard drive spins up high, the computer fails. If the fan spins up high, the computer crashes as well. Disregarding heat, as that has been ruled out, it leaves me with power as being the common factor. If this were a desktop I'd replace the power supply unit. I think that it is integrated on the motherboard here though... what to do.
:upset:

Ugh. That is effing depressing, man, but it makes sense. Thanks very much for posting what you found.

 

Re: HP Pavilion dv8000 suddenly crashes

does the backup drive have it's own power supply

 

Re: HP Pavilion dv8000 suddenly crashes

either way...

I'm scrounging pennies to see if I can buy a new/refurb one.

Re: HP Pavilion dv8000 suddenly crashes

O.k. I'm really annoyed. I usually fix my own computer issues, but this continues to baffle me and I don't have the money to replace it. The thing was running fine yesterday (except the ridiculously loud fan noise) until I cleaned it out. Now it will run for 2 minutes max if I don't run any programs or anything. If I run anything it shuts off with a click/pop. Theoretically this shouldn't be happening and I feel as though it's some relay that's stuck somewhere, (but that's not how this works, I think). If anyone out there has any bright Ideas that don't include formatting or replacing ridiculously expensive parts (under 100 is ok) then I'm listening.

Re: HP Pavilion dv8000 suddenly crashes

I have a dv8000t with the same sudden shutdown problem. I've read posts all over with no real certain answers. Xonikz above mentioned the power supply possibility. I bought a new AC adapter - not from HP - about a week ago and I'm thinking that it may somehow be to blame. I never had the shutdown problem before using it. I'm wondering if anyone else experiencing this problem also switched to a new AC charger recently.

I bought the new charger because one of my kids tripped over the power cord and it ruined the connector on the old one. It may also have done damage to the DC input jack on the laptop. Did anyone else with this problem have a DC input jack problem recently? Just an idea.

 

Re: HP Pavilion dv8000 suddenly crashes

Well, I'm back and happy to say I have it working.

The heat issue does actually seem to be the problem. I reopened it; got the silver paste instead of the cheap stuff; replaced the paste on the cpu; then, just for good-luck sake, replaced the blue goo-pad-thingy between the heat sink and the GPU with silver paste as well. It's running now and well. Played Oblivion on it just to check for possible crashing based on heat... no problem. The fan, however is back to making a low rattling noise and I think the bearing is a bit worn out or something. The replacement is 40 bucks and that's a heck of a lot better than having to buy a whole new laptop.

I'm not certain what caused the initial shutdown, but I'm willing to live in suspense for now.
:4-dontkno
(to Ibarry)
The power supply is finicky in all electronics. It's almost always better to stay in-brand when buying replacements.

glad you have yours sorted

 

Re: HP Pavilion dv8000 suddenly crashes

Hi there, I'm new to this site, I'm actually having the same issue, stupid me , i already purchased my heat sink on eBay, it should be here any day. Mine shut down on me constantly, I'm hoping to fix it and resell it on eBay.

I just built my home computer and its amazing fast compared to that junk

 

Re: HP Pavilion dv8000 suddenly crashes

Yup, it's slow comparatively... but it's also almost three years old as models go. Dv8135 me.

You should look into "gaming Laptops" if you're looking for speed.

I'm still using the dv8000 for minor animation and editing. It works fine for photoshop too.

 

Re: HP Pavilion dv8000 suddenly crashes

Sorry for the double post, but...

If anyone knows of an upgrade (hopefully dual-core) processor available for the laptop 745 socket, let me know.

Yes, that's the socket this laptop has.:sigh:

 

Re: HP Pavilion dv8000 suddenly crashes

i had the same exact problem. i rigged up my own cooling unit using a card board box and 2 antec fans hooked up to an old phone charger. i directed the flow into the bottom of the laptop using a peice of cardboard as a ramp and used the other fan to pull the hot air out of the vent on the back left side. This may sound funny but this is all i had and i did this so i could re-load windows on my cpu. I was running windows vista basic and just recently the cpu started running very hot and shutting off under normal use (even if it was just sitting there). I used my ghetto cooling box to load windows XP pro on here (because XP is what came on it originally). Finally after it loaded and everything was back to normal the cpu does not over heat anymore. It gets warm at times but only if playing games or watching movies. Just like it did when i first bought it. But it will not turn off. The fan works fine now, sometimes makes a little noise but it IS working fine. I don't know if there was some virus or soemthing that was causeing the cpu to work harder than it was supposed to or what it was. But i did notice that there was an update for my processor when i ran windows update and it said something to the extent of it was an update to allow the processor to be modified for performance. Maybe this helped it not overheat? Either way i have yet to have any more problems and haven't had to use my ghetto box. But i will keep it handy just in case. :tongue: hopes this helps you out. If you want a new fan i found the whole assembly on ebay for $35-$45. I might invest in that just in case and i also have a bad battery that i need to replace.

 

Re: HP Pavilion dv8000 suddenly crashes

my dv8000 had been randomly powering off on its own. Just sitting idle.
I use it in a fairly dusty enviroment. I suspected it was overheating and blew it out, no change. I took it in to the shop I bought it and told them my concern, adding the suggestion to take it apart, re-paste the cpu to the cooler. They phoned me after 3 days telling me they blew it out and stress tested it for 48 hrs and it didnt shut down so all was ok. But recommended that I buy a new fan as mine didnt move alot of air. "Maybe the fan is worn out" is what i was told. They took my 80 dollars diagnostic fee and returned my laptop. It was home for 1 day and shut down again while running an excel document. I pulled mine apart. (ABOUT AN HOUR)
On top of the cpu cooler and partially obstructing the fan was a patch of unidentified adhesive material approx 2" x 2". i removed the fan / cooling unit and cleaned it out. (not very dirty) but the heat conducting paste was crystalized. I replaced the compound with the silver paste and reassembled. It sure moves alot of air now.. hasnt shut off since,,
Could have used that 80 dollars for beer....:1angel:

 

Re: HP Pavilion dv8000 suddenly crashes

well i thought my problem was fixed but it is not. Sometimes i turn my cpu on and my fan will not turn on at all. The ONLY time i cant get my fan to turn on is when i leave my cpu running without the fan and let it get hot then after it shuts off, most of the time when i turn it back on the fan will work. I had to pull out my little ghetto box and fans again just to reply to this damnn forum and check my email or the thing will cut off. I just ordered a new fan off ebay and some of the arctic silver heat paste and plan to put that in this weekend. I will let everyone know how it goes and ill be sure to watch for obstacles blocking the fan. I did notice on the bottom of mine there is a piece of plastic covering the hole on the bottom but there was another forum about that and HP said that was part of the design. Well thats a ****ty design and im gonna pull it out so the fan will be able to pull more air. I will tell everyone how it goes.

 

Re: HP Pavilion dv8000 suddenly crashes

that must be what was in mine too. its like an adhesive patch. Mine didnt go back in. :1angel: Since the
repaste with "arctic silver 5" , 2 days ago, mine hasnt shut down.
and Ive tried decoding and ripping a DVD to work it a bit.
Stupid engineers...lol. lets block the airflow thru the case. I also installed
a set of laptop feet. Neat little flip up feet for laptops, creates an airspace underneath. and they have adhesive backing. they have 3 positions. down, step 1 and step 2. i actually like the angle of the keyboard better with them. (myself im prone to not hitting the spacebar hard enough...doohhhh!
:wink:
