Latitude E6400 Owner's Lounge

It has nothing to do with Nvidia, nor Dell. You problem could have occurred on ANY systems. This includes TV's, Wii's, XBox 360's and even PS3's, and you Lenovo machine that you wanted.

It's just a miss build or faulty hardware, it happens to all of us.
My desktop motherboard broke down last year, which is ASUS which is supposed to be one of the top motherboards maker in the world. I was under warranty luckily, and I had a friend who passed over 2 of them within the first month before getting a good one. Heck even happens on routers. It's just a manufacturing error. The only way to get a perfect system everytime is that once build, the system is tested for 1 year, and then given to you... and even then. And then you'll complain that "my new computer has been used for 1 year!" Soo.....
happens in life... that is part of life.

As a counter example to you, my laptop is super cool, and I even overclock the of the GPU and the palm rest is STILL NOT hot. (see signature on my guide, showing my overclock settings and results, if you don't believe me).

I saw once you get a chance, really soon, ask for a replacement one. That one should be fine. Or get the P series CPU, if you think it will be better.

 

this is the result of my E6400 tests with Everest.

CPU temp when I did not used the Laptop ( the speed fluctuates!)



and then
CPU 100% usage test for 5 minute.
CPU reached 90 C and then I stopped the test.




have u noticed that when the system come back from the Screen saver mode to normal..GPU clock goes up?
for mine, happened this way

GPU Core Clock [MHz] / GPU Memory Clock [MHz]
169.0/100.0
to
580.0/400.0
and then back to
169.0/100.0
with Fan Speed on 100% on the whole process
(based on the GPU-z)

any comments?

 

Yes, been there, done that.

 

your statement seems to be true! that's why I really applause Motorola for their 6Sigma efforts!

dude, u r so lucky to have such a cool laptop!
u are Overclocking! I am thinking of Underclocking!!!
can u tell me your CPU, GPU and HDD temps at different conditions?

 

CPU and GPU has a system that when it heats up too much it downclocks.
Also the GPU has Nvidia PowerMizer technology (similarly for AMD CPU's, and as for Intel it does when Windows is set on Power Saver mode), which keeps the processor of the device (GPU or CPU) at lowest settings, and only increase when you need the performance.

On my desktop computer I have an AMD Athlon 64 4400+ X2 on Socket 939. It is a dual core (the first desktop 64-bit dual core CPU, in fact) and a Geforce GTX 260. Running Vista 64-bit (if you ask, but does not mean anything)
My CPU is at 800MHz when idle. It's so cool that you see each fan blades turning. But the second I open and application it jump to it's max speed at 2.2Ghz, and when under load it automatically overclock a nice 10% to reduce system slow downs when CPU is too in demand.

As for the Geforce GTX 260, this is a power heater right there. Why wait so much heat and energy for nothing? So the GPU downclocks when idle (using Aero), and when I play games it kicks in at full speed, the fan turns faster making your computer from an ultra quiet air cooled system to loud one.

As for you, when exiting a screen saver, you have Windows Vista (same for Win7), the interface, unlike XP and previous versions of Windows, is rendered by the GPU as the CPU sucks at it. CPU was NEVER designed to draw. Don't believe me. Get out your old computer with XP and move a window, you will see that your CPU will spike at 100%. Get a P3 800Mhz with XP theme, and you will see the screen drawing every time you move a window, and when you move a mouse the CPU spike at 50%.

All this major downside that no one complained, to drop computer costs as video cards are really expensive. So expensive in fact that a Geforce FX 5200, which was an expensive video card compared to Intel integrated option or the equivalent to ATI, and it has a hard time drawing Aero. Polygons, moving objects, particle effects... fine. Transparency, blur, texture based on a loaded bitmap, fur, proper shadow (to name a few)... you can only dream back then. Yes it LOOKS simple, but it is not. It's actually VERY complicated for a GPU to render.

Even today, in game shadow still needs a lot of work, and a game with a mirror... well it basically redraws the same room you are in in low quality. Yes, even if you have a Geforce GTX 295 triple SLI, it's still not good enough.

Anyway... so in conclusion the GPU behavior is normal.

Try this, remove the heatsink... check if the CPU thermal paste is touched on the heatsink. Make sure that Dell did not forget to remove a plastic sheet on the CPU or thermal paste as Microsoft did on many xbox 360. Do not remove or replace the thermal paste you will void the warranty.

 

thanks for the info....
by the way...I think I passed a shock. I feel a little bit better now!
because at least I know what's happening and what I can do & what I can't!

 

Thanks for the quick reply and sorry for the turtle-slow answer, John.

It turns out Dell put a CD-RW/DVD-ROM in my laptop I'm going to have to contact them to get it replaced with a DVD+/RW drive. No wonder it wouldnt read my blank DVD+Rs!

 

My system specs are on my signature.

Normal usage of system (at this moment, High Performance):(Nvidia powermizer is disabled), so these these are high points, especially I just played some Flash video.
CPU: 51C
CPU 1: 51C
CPU 2: 47C
Chipset: 62C
Ambient: 46C
RAM: 47C
GPU: 66C
HDD: 37C

Idle Temp: (powerMizer enabled, Power Saver)
CPU: 35C
CPU 1: 35C
CPU 2: 30C
Chipset: 37C
Ambient: 38C
RAM: 37C
GPU: 40C
HDD: 34C

Load Temp (System, HDD and GPU | High Performance):
CPU: 66C
CPU 1: 63C
CPU 2: 63C
Chipset: 66
Ambient: 46C
RAM: 50C
GPU: 88C (it did peeked at 91C but the fan went faster after and turns it down to 88, which makes the fan turn a little slower... so it switches between 88C and 91C)
HDD: 39C
(Using Lavalys Everest system stress and FurMark). This is is REALLY intensive stuff here.
Side note: Hey! My fan takes more heat before going max speed with the latest BIOS A14 . But take that as a grain of salt.. it might just be a placebo effect.


Heavy load Temp (System, HDD and GPU. GPU IS OVERCLOCKED | High Performance ):
CPU: 69C
CPU 1: 68C
CPU 2: 66C
Chipset: 88C
Ambient: 47C
RAM: 50C
GPU: 95C
HDD: 39C

NOTE: CPU and other components are warmer then under Load, as the GPU heats up more and it is using the same heatsink to cool off everything.

 

anyone wanna chime in here?

http://forum.notebookreview.com/showthread.php?t=383917

thanks...i am going nuts.

 

anyone have any suggestions on the best way to troubleshoot a system that is not automatically suspending? And suggestions as to what it might be? (running programs below) running win 7 RC (7100) -- clean install. the weird thing is that i basically had all of the below software installed in 7077, and did not have this issue.

currently installed
VMWare
Symantec Endpoint Protection 11.0.4014.26 (should be working)
daemon tools lite (4.30.4.0027)
comodo internet security (with firewall only) 3.9.95478.509
intel mywifi
dell webcam central
logitech setpoint
logitech LCDManager
Logical game panel (g15) (g-series key profiler)


thanks in advance for any suggestions/advice.
