HP/Compaq :: Maybe This Is The Reason Why The 8400M And 8600M Keep Failing

Jul 23, 2009

I just discovered an interesting issue after undervolting my DV9700's CPU and overclocking its graphics chip but forgot to post it earlier. When playing GTAIV (which is extremely GPU intensive as you know), the whole notebook will get warm. I already know from FurMark that my 8400M GS will reach 80C in its current configuration so i can understand why the thing gets warm. However the fan always runs at minimum speed when playing GTAIV...

This leads me to believe that the cooling fan is exclusively controlled by the CPU temperature. It wouldn't matter if the graphics chip would be on fire - the fan will still not ramp up unless the CPU reaches the temperature threshold. I'll check exactly what these threshold values are later, but i remember that on my DV5 it's 75C for high and 85C for maximum. The fans on these things have 4 speeds IIRC.

Now, my DV9700 is a large and rather solidly built machine. It easily copes with the heat even with the fan turned down, i have no issues with GTAIV or any other game, and if you recall it had a faulty fan when i got it yet it was still able to work for 20 minutes before reaching shutdown temperature.

But if this is true for all laptops, i can see why these GPUs fail. Notebook manufacturers should consider implementing a fan controller that reads from both CPU and GPU sensors.

Dell :: My 8600m Gt Is Thermally Failing

Jan 2, 2009

my m1530's 8600m gt is now idling between 69-73 degrees celsius, as opposed to the 58-65 it did when it was new. also, in-game temps are now well into the 90's. will be calling dell support this afternoon to have them set up a tech to come out and replace it.

Dell :: M1530 8400M Vs 8600M

Jun 5, 2009

Currently my M1530 has the nvidia 8400M GS chip in it. I'm thinking about swapping the motherboard out for one with an 8600M chip on it.

My question is, will it make much of a difference? How much greater is the 8600M w/ 256mb versus the 8400M w/ 128mb that is currently in my machine? Look forward to your responses.

HP/Compaq :: Is There Any Reason To Get A Dv4t Over A Dv3t

Jul 12, 2009

Looking at the HP site these days, the dv3t gives you free 320GB HDD, Included LED display (at 1280x800), and long battery life.

The dv4t has only a free 250GB, extra $60 for LED, less battery life, and costs nearly the same (Infact, only $20 less for the same specs asthe dv3t).

Why SHOULDNT I get the dv3t? I'm in the market for a small, light PC with 512MB Discreet graphics and something around 2.2-2.4GHZ Intel. Seems like dv3t is the no brainer. Considering smaller computers tend to be more expensive it surprises me that HP offer more free upgrades on the dv3t than on the dv4t.

HP/Compaq :: Failing 9600m GT

Jan 24, 2009

I got my HP DV5t about 4-5 mos. ago. The graphics card which is a 9600m GT is definitely starting to fail. When ever I start to play graphically intensive games like COD4 or CS 1.6 the screen begins to freeze and the computer says the display driver failed while other times it causes a BSOD. This used to happen occasionally about 1-2 mos. ago but now it happens very often. I updated my drivers as soon as I got the laptop and always lifted the back for better airflow while gaming but apparently it didnt help.

HP/Compaq :: Where Is The Shader Clock- Dv2700 / 8400M GS

May 11, 2009

I have been reading the threads related to HP notebooks with defective nVidia GPUs and just out of curiosity, I checked the 8400M GS GPU in my roommate's HP dv2700 notebook, which normally runs @ 80 - 90 deg C, using GPU-z software. The sensor data matched the default core / memory clock for 8400M GS, when under stress. But I got confused when I saw that the shader tab is disabled .

I do not know if somebody else has already come across this situation. I searched here and could not find a similar reported problem, hence this thread. Am I missing something here or is there someone out there having the same problem. Can it be something related to an older ForceWare version (156.65)?

HP/Compaq :: NVidia Setup Not Detecting My 8400M GS Graphics

Feb 19, 2009

This has been getting on my nerves lately. In the past, they never bothered releasing drivers for laptops but now that they do, I can't get it to work with my laptop, which is HP Pavilion 6670ee with NVidia 8400M GS...

I know that 3rd party driver will work with it but I am not able to get the PhysX support with those drivers for some reason and if I download Notebook driver from NVidia website, the latest which they released few days ago for example.

I get this error during installation:

The NVIDIA setup program could not locate any drivers that are compatible with your current hardware. Setup will now exit.

It's NVidia's own 8400M GS - wth is it not detecting it?

HP/Compaq :: DV9500 W/ 8600m GS

Jun 25, 2009

I have a HP dv9543cl that was purchased at Costco sometime in late 2007. My nVidia 8600m GS in the laptop started to break down in the summer of last year by presenting symptoms such as system lock-ups, freezing, unable to boot the computer due to video problems, etc. Eventually, the video card finally died in March of this year.

So I recently sent it in to HP (apparantly I had a 2 year warranty on the laptop... something I didn't know. Heh.) I told them of the nVidia issues and etc. so they agreed to replace my motherboard.

I got my laptop sent back to me by HP today with a replaced motherboard and keyboard as a bonus I guess. Anyway... looking in GPU-Z, I notice something strange from the original specs of the nVidia 8600m GS. The GPU clock speed and the memory speed is lower than specified on the nVidia website.

Also, I'm wondering, with this replacement... will this video card die eventually also? Or has nVidia given HP a new 'batch' of chipsets to replace the broken ones?

Here's a pic of my GPU-Z:

Also, my nVidia card is running (idle) at 69C. Is this normal/not unusual operating temperature?

it is "Dox Optimised 181.20:Performance",

HP/Compaq :: Underclocking Th 8600m Gs In A Dv9700t Cto

Jun 19, 2009

I've recently gotten my whole system board replaced by HP repair because my 8600m gs failed after 1 year of use. Is there any way I could underclock my GPU? The idle temps seem pretty high (50c!). Are there any other ways to cool it down or to make the life the GPU longer? Are the replacment GPU's also faulty?

Dell :: Any Reason To Not Delete The Recovery Partition?

Oct 22, 2009

I have an m1530 and my Windows 7 is on its way! I currently have 10gb just sitting there doing nothing thanks to the recovery partition from the factory and I was

thinking of deleting that partition and creating a 50gb partition for windows 7 and having the remaining hard drive as storage for an easy future formatting environment.

1) Is there any reason to keep the recovery partition and am I safe to delete it and regain my 10gb?

2) 50gb might be too much, but Im not too sure what the windows 7 fingerprint is (15gb?). What is a good OS partition size for windows 7

Dell :: Studio 15Volume Buttons Blinking For No Reason

Oct 16, 2008

I just got a brand new Studio 15 laptop a couple of days ago. So far, I love it, but there's one really odd thing. All day, the mute and volume up buttons have been blinking, and the volume down button has just stayed lit. There does not appear to be any reason for them to be doing this. Also, it's not affecting the buttons' performance. Does anybody have a theory as to why it's doing this? And is there any way to make it stop?

Sony :: Vaio Z (590) Coming Out Of Hibernate During Night For No Reason

Aug 31, 2009

I put my new laptop into hibernate and into my laptop bag. At about 3 am (I looked at event log) it seems to over the last few days come out of hibernation and come on. Within 10 minutes it goes back to sleep/hibernate. This happens while I am not even touching it. Would this have caused any damage (heat while in bag)? I doubt it but it is new and I am paranoid! Also for now I am just shutting down if the laptop is not plugged in and not in use.

Lenovo 11e E/Edge :: ThinkPad E15 Not Charging For No Apparent Reason

Aug 18, 2012

I have a ThinkPad Edge 15. It had a charging problem from the day I purchased it. The people I bought it from sent it back to IBM/Lenovo who apparently tightened the area where the charging cord goes into the PC?
That did NOT fix the issue, so when I got my laptop back, I called LEnovo, they sent me a new battery (even though I told them the 'Power Manager' said the battery was in good condition) which did nothing. Then they sent me a new charging cord, again-nada. They sent me a box to send the laptop back to them. As I was figuring out how to put the laptop in the box, I looked over @ my PC, and lo and behold; the light that tells you if it is charging was shining!
Last night. I looked @ the charging icon; '15%, not charging'! Oops! Oh dear, not again! Went to power manager, everything is just fine. Checked all of my connections, same thing. I left the laptop plugged in. This morning as I look over @ the laptop & Guess WHAT! It was charging, the light was on! I turned it on...

Dell XPS L702X :: Optical Drive Randomly Started Opening Itself For No Reason At All

Jan 28, 2013

Recently the optical drive on my XPS L702X laptop has randomly started opening itself for no reason at all, and the button to open it on the drives face plate does not respond either.

This has started happening just a few days after the warranty has expired so i'm hoping its not broken but it seems doubtful if i'm honest.

Also the connection for the power lead is extremely poor and the slightest movement causes it to fall out, i've searched around and it seems to be a fairly common problem on these laptops but i haven't been able to find a solution as of yet.

What with already having 2 failed hard drives and now these 2 new issues, it sure doesn't seem like dell laptops are made to last anymore.
