NOT AGAIN! My Latitude is overheating and the CPU is maxing out:

Again, if anything "deteriorates over time", it's probably not the system. Software problems such as the "Windows Sharing Device" (which didn't turn up anything on the web about it) are definately OS related. Heat problems that appear after time indicate dust is present or the thermal grease needs to be replaced.

I wouldn't be surprised that there are heat/throttling problems with two displays. Especially if the systems are using integrated graphics. You really should be using a desktop if you're driving that much equipment. What are the temperatures like when you're running two displays?

 

I have run Throttlestop to see how it works but haven't needed to use it for its primary purpose. UncleWebb, the program's writer, it around if you need help. Given that the throttling is caused by a glitch and not by dangerously high temperatures, I would not hesitate to use it if in your circumstances. RMClock will also work to control throttling on the E6400 and I did use it when my E6400 was new and the BIOS throttled the CPU when I connected a 65W PSU. With RMClock it is easy to enable throttling and then select the 100% value.

Run MSCONFIG and disable the sharing service on the Services tab. Also see what else is listed under Services and Startup that you don't want.

Not me. Use twin monitors at the office on a docking station and a Dell 30 ultra high res at home on a docking station. CPU is at 48deg here at the office, It run a few deg cooler at home. This is with throttlestop active. If I turn it off, my system will throttle down to less than 1Ghz. Yes, its a design flaw in the dell system. They seem to have no idea how to fix it. Throttlestop does.

 

Sorry, this is utter BS. Twin displays or ultra high res large format monitors were specific selling features for this line of 'desktop replacement' laptops. They function GREAT in this application.

 

These laptops are not desktop replacement, the Precisions are more likely to be marketed as such. The docking only gives you a desktop-like experience and isn't designed to replace one.

I'd like to know where. I have never seen Dell literature mention this before.

 

Im going to try throttlestop.
Was it easy to use on the first go?

Just a little nervous that I may do something that cannot be undone.

 

akwit: Did you have some Valium before trying ThrottleStop? The way you're talking it's like you think your whole damn house is going to burn down.

What can it possibly do that can't be undone? If you don't like ThrottleStop, delete it, reboot and life goes on.

When it is running, push the F1 key on the keyboard and you can read some more info about it. I always answer my PM messages so if you have questions send them there. If I'm sleeping it might take me a few hours but your questions will be answered. Too bad all freeware software doesn't have that kind of support.

There are many happy users in the Latitude E6400 forum that have used ThrottleStop to solve their problems.

HUH?

How exactly am "i talking"? Im sorry if my concern for my $2K investment or its associated warranty somehow bothers you.

 

Support for twin monitors and the Dell ultra high res 30" display are specificly mentioned in the sales specs for the E6400 and again in the specs for the E-Dock, way back when first released. Our company was one of the first to widely distribute them among our users having leased several hundred of the first production run. I was one of the first to attempt to use the Dell Ultra 30" Displayport display. Did not work with the first bios and Nvidia drivers but dell recognized the spec to do so right away. Had it working in a couple weeks. That same laptop is still driving that 30" display as I type this. Yes, the Lattitudes were marketed to businesses as mainstream desktop replacements for business use and we deployed quite a few. No one expects them to handle the duties of a 3Ghz Quad Core desktop. Most business users do not need or depoy such extreams. The E6400 has had a good track record as well so far. Yes a few have the throttling problem, mine included. Most do not or the users don't know enough to complain about it. Again, throttlestop solves the issue, has no negative effects. We have had no overheat damage warranty replacements. What few we have had have been screen failures, HDs and a couple unknowns. All have been handled promptly under our service agreement.

If you don't want to fix your problem with throttlestop, fine. Sell the laptop and get something else. Every laptop has its share of 'issues' This one has been far easier to deal with and more reliable than its predecessors.

 

akwit: I told you almost a month ago on September 11th when you first started this thread about ThrottleStop as a solution to the throttling problem you are having. It is a well known issue with the Latitude E6400.

Here is Randall Cotton's 59 page pdf that clearly documents this problem.
throttlegate.pdf

The bad press Dell got after that was released encouraged Dell to make a few minor bios adjustments but that never fully solved the problem in the Latitude E6x00 series. If it did solve the problem, the E6400 throttling thread wouldn't still be going on and on.

I apologize but when it takes you a month to solve a problem that ThrottleStop can solve in under a minute of download and setup time, that's being more than "just a little nervous."

Thousands of people world wide are using ThrottleStop to solve their problems. I haven't seen a single thread on NBR stating that ThrottleStop caused my computer to start on fire or wiped out all my data.

Edit: Here is the type of load a properly designed laptop is supposed to be able to run without throttling or overheating.

No one with a Latitude E6400 has shown me that their laptop is capable of that without throttling itself to death. It's a design defect on Dell's part that the previous generation of Dell Latitude with similar specs didn't have.
