Dell Latitude E6540 OR Precision M4800 ..........!

Hi,

I am looking for new laptop and confused between below two.

Dell Latitude E6540 OR Precision M4800 ..........!

I already own Latitude E6540 from last two years, now it is getting warm and hot and some time blue screen and shut down and now slow too.

I need something better, longer working hours in normal environment (no air conditioner and 45 degree temp.)

Price is not a problem.

I need a machine that can work for 18 hours a day without shutting down.

I am not engineer/designer/developer, but my usage is full day in open weather in sun light.

So please share your experience and help me to choose right laptop.

Thanks

 

Sounds like your current machine is overheating, have you tried cleaning it out and reapplying the thermal paste on the CPU/GPU? For the most part thermal paste applied by OEM's is about as good as chocolate so applying some new stuff is always a good idea!

Before I recently upgraded I had a Dell Latitude E6420 with the Nvidia GPU, it would overheat a fair amount under load so I had a look at the cooling only to find some pretty dry thermal pads on the GPU/Chipset and thermal paste well past its best on the CPU so I used copper shims in place of the thermal pads on the GPU and some Arctic 5 thermal past on the CPU.

After that my temps dropped between 10-15 degrees under load!

 

Is that 45 degrees Celcius or Fahrenheit? The former would be unpleasantly hot (I've found that above 35C dripping sweat becomes a hazard to the computer) while a computer running in 45F should never suffer from overheating unless the fan is broken.

I would support the recommendation to service the cooling system. Also make sure that the air vents aren't blocked with fluff.

Regarding alternative computers, do you needa discrete GPU or would the Intel graphics be sufficient? The latter means both fewer heat-generating components and a simpler heatsink configuration.

Precision has a really good cooling system, and is normally what I would suggest if you don't care about price and portability. (It's a bit heavier than a Latitude, and the power supply is larger as well.) Latitude will probably last longer on battery if that matters to you.

 

You'll probably still be outside temperature specs for the M4800, but given that it was designed to run at full CPU and GPU usage for long periods of time, it should be able to keep itself cooled during normal use at those temps.

You'll also have two fans to cool it down, prop it up a little to give it better airflow.

 

Note that you won't get much run time on battery at full CPU/GPU load.

 

Question is still due.

Either Latitude or Precision ?

 

Please guide more, still not decided.

Precision users please share your experience.

 

Not necessarily true. Do Latitudes not come with less capacious battery as default?

 

M4800 is simply a much better-built computer with more options. Neither I am engineer/designer/developer. I just wanted a solid portable computer (a thing that can actually compute when needed as needed ). The slight pay-up pays off big in the long run. I have never regretted my choice.

I suggest you look at this thread: http://forum.notebookreview.com/threads/dell-precision-m2800-owner’s-review.755528/
(M2800 is basically the same thing as E6540 but with a (cheap) pro GPU.)
