Revived my HP dv8200, now new Problems!

Hey guys,

Here is some background to my problem:
Well first off I really liked this laptop (when it worked) About 8 months into owning it, the fan was getting louder and louder it sounded like I was in an airport. I never sent it in because I couldn't afford to NOT have it at the time.

So I held onto it, and randomly while playing some computer games on this laptop it would shut down due to overheating. (Bottom felt REAL hot) and I realized it was because I had it laying on the bed.

So one day, my laptop doesn't start. I try everything I can think of, with new cables, and battery, but no matter what I did it would not start. I was getting quotes of $400 to get it fixed. So I decided I will take it apart and try to do it myself. I replaced the fan, put it back together. And alas it starts and is quiet again.


Everything is going fine now, EXCEPT when I launch a few programs, OR even attach something like a webcam. BAM screen goes out, waits 5 seconds, and shuts down. I check the temperature, and it is fine. 31C usually. From nVidia monitoring tool.

I am at a loss, I don't really have an idea WHY it is randomly shutting down, Basically the fan will start spinning more, and then it shuts down. I am pretty sure its not due to the install, (pretty straight forward). Is the fan shorting something, is the power button or something due to powering shorting it? Or can it be a completely separate issue?

Anyway sorry for the very long winded first post. I thought I'd give it a shot, and was wondering if anyone ever heard about such a problem. Thanks!

 

Bump

I updated the BIOS firmware but that didn't help.

 

to me it sounds like your not getting enough power not sure what would cause it because you said you replaced a/c adapter. i have a dv8230us and i personaly think it is nicer then my dv6500t it has a better more solid feeling build to it and it boots faster my dv6500 hangs for like 2 minutes durring vista boot up.

 

I think you may have damaged some of the internals due to overheating by placing it on your bed. What happened is that you were blocking all the vents so the heat built up. This would also explain why the fan was increasing because the heat was building up. Additionally, gaming while blocking the heat vents is especially bad because that's when the computer needs ventilation the most. Overheating would just affect the fan, it affects ALL of the internal components and could easily damage them. Are the programs and over stuff you're trying to launch resource heavy. I think the fan is still the problem. It may be that when the fan tries to kick in it can't and some hardware malfunction happens. Worse still, since you opened up your laptop you voided the warranty. HP probably could have repaired or replaced your laptop. You should never open up your laptop unless you know exactly what you're doing and the consequences of your actions. So to wrap up, I'm pretty sure you have a major hardware problem due primarily to overheating and possibly due to the self repair.

 

thanks jin for the reply, and sorry for the very VERY late reply, But I got all tied up in school.

I'd like to update though. First off the laptop was well past its warranty, so I'd have to dish out something like $400 for the fixes. (was quoted by 2 places) Definitely not worth it for me, thats why I took a chance.


As for the laptop, I narrowed it down by using SpeedFan, and my laptop was no longer heating up like it used to. (it would feel cool to the touch right after shutdown) So that threw me off, but the temps showed the truth! My GPU core temp would rise as soon as it'd need to do work, it would go from 40 to 70 to 80-90-95 then shutdown. And we're talking within 1 minute.

My fan is working fine, it was my thermal paste! I left on the old blue thermal tape stuff during the first fan replacement install, and didnt' reapply for the processor. So there wasn't direct contact, and an obvious reason for the soaring temperatures and random shutdowns. I got some Artic Silver 5, and placed it on all 3 heatsinks, and viola. No more overheating, ALSO I got a laptop cooling pad to help with temperatures.

Furthermore on overclocking.net I found a guide on how to Undervolt your laptop. And it seems to drop the temperature even moreso, so I'm going to give this a shot as well, to avoid anymore heating problems.

I didn't know much about laptops when I got this HP and treated it like crap, never realized heating was such an issue. Although its obvious now. I guess I'm REALLY lucky I didn't fry my internals. Upgrading it to 2GB ram, and this thing should last me another year or so.

 

Yeah...running without thermal paste will definitely do that. When I saw this post I asked myself, "I posted in this thread?" Seems like a long time ago. Didn't know you actually messed around with that stuff or I probably could have narrowed it down to that.

 

Yeah I noticed some articles about thermal paste, and then it just hit me DUH! And I like to tinker with my things, and it was quite a good learning experience overall. Takes me about 10 minutes to take apart the whole laptop now.
