Dell Latitude E6400 - Overheating issues with minute tasks such as playing flash videos for extended periods?

I'm not sure if this is happening to anyone else, but I've recently been experiencing some serious issues with my Dell Latitude E6400 (with latest BIOS, and all other relevant updates) while surfing, playing flash videos full screen, etc. After extended periods, Windows Vista slows to a halt to the point I can barely minimize a window without severely delayed lag. I've also noticed that the typical games I play have also had its frame rates severely slowed down as well.

I have been trying out Mozilla Firefox 3.1 Beta 2 and also the latest ESET Smart Security 4 Beta, but I've doubt these are the culprit. Just for good measure, I've uninstalled these but the issue still seems to persist.

As I use this mainly for graphic design (using latest Adobe CS4), it's quite critical to be able to handle most of these tasks. For that matter, as a $2,000+ laptop, I'd at least assume to be able to surf and play flash videos without issues. I've been told my Dell tech support to run Diagnostics, but everything seems to complete successfully. They haven't gotten back to me again yet - but I've purchased a 3 year Complete Cover warranty - what am I to do?

I'm a Canadian consumer and have heard nothing but the best from them - but as I am currently lodged in Hong Kong, I purchased this through Dell Hong Kong and am worried that my warranty (even though purchased), will not be rewarded as well as the Canadian counterpart without a severe delay - which means my work will be compromised.

Any ideas would be great!

Re: Dell Latitude E6400 - Overheating issues with minute tasks such as playing flash videos for extended periods?

Hi Mr_Dimsum,

all I have to offer are ideas, but since I logged on to the Dell Community today to get help with a similar problem I thought I'd share my experience.

 

Some processeors will combat overheating by reducing their speed (as you pointed out). One way to check it is by downloading a program that can read the temperature sensor on your CPU. One alternative is CoreTemp. (http://www.alcpu.com/CoreTemp/) I never tried it though but it should be able to tell you if your core is too hot. 50-70 C is OK, above 80 C is bad. Also, flash can be pretty intense for the computer, even if it might not look that way. (E.g. Flash was able to overheat one of my old computers.)

 

If your cumputer is indeed overheating, that can usually be dealt with in the following ways: 1) Blowing out dust with canned air. 2) Checking and possibly replacing fans. 3) Making sure the CPU conducts heat to the heat sink, and possibly replacing the heat conductor inbetween the two.

 

Good Luck!

You should also check the task Manager to see if any services are grabbing CPU cycles. Some Services and programs can severly slow down desktop performance without showing 100% CPU usage. You need to do somwe snooping to see what is happening. If you stop all work does the response get better or not? Doing the temperature measurement is critical.

Re: Dell Latitude E6400 - Overheating issues with minute tasks such as playing flash videos for extended periods?

I got exactly the same problem here The computer don't work after some time viewing Video and its even worst with DVd playback (cant watch more than 20 minutes)

The problem seems to be an overheating from the Graphical chipset (ie Intel for me not NVIDIA)

The processor doesn't overheat (45-50°c with SpeedFan), when video playback it doesn't use more than 40% UC but when the overheat occurs It peak to 100% and the taskmanager doesn't show any anormality

The heat come from the chipset (the chip in the middle jsut next the DVD player)

I got the problem with Vista x64, 2008 x64 and even a clean install of Vista x86

All test with SP1 and the SP2 Beta.

And with A06, A09 and A11 BIOS

I just installed everest to have more info.

when the chipset is overheating my 2.8 Ghz proc fall to 500 Mhz and the FSB (usally 266 Mhz) fall to 73 Mhz

Re: Dell Latitude E6400 - Overheating issues with minute tasks such as playing flash videos for extended periods?

HI, 

I am having the exact same issues.. intrestingly always after around 20 minutes of watching video footage (or video editing).  Whether its online hd or from the flip (minoHD / www.theflip.com) in VLC.

The CPUs are ok, but bounce to 100% when it happens, just with the usual windows apps. However temp is only at 40-50°c (cpu-z / speedfan), which leads me to believe that its the graphics chip. After it slows down, it doesn't pick up again unless I leave it sitting for an hour. Turning off and on the machine temporarily resolves the problem... but who can deal with that every 20 minutes ?? (the time decreases, the shorter time you leave it off) 

Are people with the NVIDIA graphic cards also affected or only the people with Intel GMA chips who are suffering? 

I was planning to downgrade to XP, but since it's obviously a hardware problem, there seems to be no point. 

Is there noone from dell picking this up? Can anything be done? If its just the Intel- GMA chip and not NVIDIA, send me an NVIDIA gfx chip (if it can be replaced) =)

CPU  2.56 / 4GB RAM / GMA 4500 / Bios: A12, running Vista Business.. and losing my patience quickly...

Same here.

E6400 - latest drivers, BIOS etc.

Playing 20 minutes a 3d Game (and it runs perfectly fast) will lead to a painful slowdown of the whole system.

Can't read GPU temp with GPU-Z.

Cores are cool as to HWMon. Just betw 30-36°. ACPI THM_ is about 45°. HDD 35°C.

Running in E-Dock on external 22" 1650

We're not the only one. But is there a cure?

Intermittent Issues on Dell's Latitude's E6400, E6500 And Precision M2400, M4400

An issue has been identified that can affect the Latitude E6400, E6500 and Precision M2400, M4400. The issue is intermittent and can manifest itself as a random BSOD, USB failure, Windows® freeze and corrupt video.

Replace the Memory, If the System Has Elpida Memory Part Number NY687

The solution is related to the 4GB system memory part number NY687 and the vendor Elpida. If the system does not have this memory part number, follow normal troubleshooting. If the system has this memory part number and it is Elpida

Re: Dell Latitude E6400 - Overheating issues with minute tasks such as playing flash videos for extended periods?

Thanks for the hint.

No Blue Screens, hangs or anything here. System runs excellent. However, when looking a Video, or even a screensaver of Vista heats the Intel GMA until the system throttles the GMA, Chipset and/or processors.

Might be a driver, Bios issue which some more people have, as found using google etc.

Lates Intel drivers (from Dell support homepage) installed.

Re: Dell Latitude E6400 - Overheating issues with minute tasks such as playing flash videos for extended periods?

Dell support mentioned, that some latitudes have problem with the heat pipe, so that the Intel GMA chip is not cooled correctly.

Any news from anybody else?
