E6410 Owner's Thread

Not 100% sure about the E6410, but at least on the E6400 they did not have the brushed texture.

 

Hi! I'm new here and I'm looking for help on a faulty temperature sensor (I suppose).

My beloved e6410 started to shut down at minutes of power on. I noticed the fan didn't start, so I removed and tested the fan, It worked fine, so I imagine there's a faulty temperature sensor or fan controller. In a computer repair store they did confirm my diagnostics (without really tested anything) and offer me a quick and cheap repair: connect the fan directly so it would be always on. It works fine (several months now) when connected directly to a power outlet, but of course on battery it consumes a lot more, so now I have a poor battery life. I'm wondering if buying a new (or used) motherboard would resolve this? I suppose the answer is yes, but I'm afraid of buying the new motherboard and find the problem where located in a different component. Any comments? Any help would be appreciated.

(btw sorry for my bad English)

 

If you connect the fan back to the proper fan header, do you still get spontaneous shut downs? Is it so bad such that you can't even get into Windows to check the actual temps on the CPU?

 

Thank you for your comment C. Wolf,

Well I didn't connected back but It wasn't able to get to windows. At best it got in to BIOS for some seconds, but I checked the CPU temp using my fingers and even when its not a precise temperature, you can believe it was really hot! Enough to burn my hand if I placed in touch for more than an instant, (I touched the heat sink, not the actual CPU of course) so I'm very sure it was shut down because of CPU temp. As I said the fan didn't move at all.

 

Try putting it in the freezer for a while, take it out and try to boot it. It should be plenty to try to get to windows. Then see if you can launch RealTemp to check temps.

If you touched it and didnt actually burn your fingers, it means it's not hot enough. If it ran 90C degrees, you would have burned them even with split second touch.

 

Also just make sure you cleaned properly that have the right thermal compound for cpu/heatsink.

 

Not a good idea...condensation would turn into liquid as the laptop defrosts.

 

Hi,

I have an E6410 with an i5-540 and the NVS3100m discrete graphics.
During normal work I encountered massive performance issues.
Throttling started and the system had severe issues to get out of it again.
(100% CPU usage though nothing was going on, I think you know of this problem)

I did some work on the cooling system to improve it, but the CPU will still clock down when putting a lot of stress on the Nvidia chip.
There won't be any issues during work now as the system won't go over 75C with 100% CPU usage anymore, but I am not fully satisfied yet.
(Before the modifications it got near 100C pretty easily and the issues started appearing...)

My changes:
-Put good thermal grease on the CPU - works very well
-1mm thick thermal pad with 7W/mK on the GPU (Phobya XT)
Whatever was on there before (it was neither grease nor a pad, something in between) had aged too much
-Pushed the heatsink down at the cooling exit, this helped to lower temps by another 5C on the GPU
-No change to the Chipset pad, it still looked fine

When running some graphics intense applications the NVS3100m reaches 100C quite easily.
As soon as it reached 100C the CPU will clock down.
I've got the feeling that the fan is not running at full speed at this moment, so the fan implementation seems to be totally screwed by Dell...
Anyone knows what is the max rpm for it?
I am on the latest Bios and quite disappointed that Dell didn't manage to solve the fan control issues in all these years.

The GPU idles at around 70-75C after some hours of office work.
Note that it always stays at 1V instead of 0.85V because of two external monitors, this increases heat a lot which seems to be a major issue.
The GPU stays noticeable cooler when running on battery (a bit below 60C) as it only gets 0.85V.

I think the best way to improve this even more, would be to force lower maximum frequency and voltage for the nvidia chip, anybody knows how to do that?
Do you think that a copper plate instead of the thermal pad would be a huge difference? The thermal pad is comparable to rather good thermal grease already (they have about 9W/mK, the pad around 7W/mK)

 

usgs, I'm new here, but may I mention that after lots of problems very roughly like yours, my current setup on this (from approx 2011) E6410 is working OK (knock on wood, etc)

The system I mostly use is a variant on an older Puppy Linux, see Puppy Linux Discussion Forum :: View topic - Lucid Puppy Revitalized as 5.2.8.6!
The wireless adaptor is not exactly yours, it's a Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01)
Somehow it works OK all the time, (cross fingers)

Hi,

it seems to be long forum i want know is there any modified bios of e6410 that can have customs table of acpi to control speed of fan
