Latitude E6400 Owner's Lounge

If you have another notebook lying around with a glossy display, just compare the screens. If your screen is washed out compared to the glossy display, you have a ccfl. If your screen is just as bright and vivid as the glossy guy, you have the LED.

You can also check with technical support. They have the actual correct specs of the laptops.

 

So this would be a CCFL screen as opposed to an LED screen?

 

The Latitude screens are matte, not glossy.
The specs on paper don't always match the actual build components.

 

Please at least try to read what I said before responding. I said if you have another laptop that has a glossy screen, try comparing it to the E6400. If the colors look around the same, you'll know that the E6400 has an LED display. If the E6400 has a washed out screen, you'll know its CCFL.

 

Question,

I have noticed that on the replacement that Dell sent to me, the bottom access panel isn't as even as it could be. Meaning that if I press down on the right side, it'll give a bit. And when the screen is open, if I pick up the laptop from the screen on the left side, it'll actually see-saw a bit...

Not the biggest concern in the world, but after getting a really really terrible first laptop, I'd like this replacement to be perfect even if I am expecting the impossible. I'll give Dell another call tomorrow and see what they can do for me. However, I really hope they can just send me another bottom access panel without me needing to send in the entire unit, that would really just annoy the heck out of me.

 

And let's not assume I have the aforementioned CMO 1441 screen in front of me to make a comparision with another screen; if I did have it in front of me, I wouldn't need to compare it to a random glossy screen to determine whether it was an LED or LCD - besides comparing colors between different screen technologies & manufacturers is really not conclusive by any means.
So - I'll go back to my original question, to anyone who actually owns one, and knows - is the CMO 1441 an LED or an LCD screen?

 

Hey guys I got a few issues that've come up w/ my E6400 and was hoping for some guidance:

1. The battery management when plugged in versus without an AC/adapter:
The first couple weeks I had this thing I would easily get 3.5-4 hours of charge surfing the net and doing word applications and typing with the WIFI on and at whatever automatic setting the laptop reverts to when unplugged. More recently (only 1.5 months after purchase) I have been only getting 2 hours of charge! I don't know what I did... I know just before this started happening I DID tinker with something in the menu where you right click on the plug icon in the taskbar and then click Adjust Power Properties, but I think all I did was change the time it takes to shut down the hard drive and monitor, etc. when running on a charge, nothing to do with the running on battery. For whatever reason though, now when I unplug, my setting goes from Home/Office to Home/Office (it doesn't change to anything when running on batteries) and even if I manually select dell maximum battery life or maximum battery life, I still only get 2 hours MAX! I'm baffled! I don't know if there is a setting in DCP or something else that might be screwed up? Please advise.

2. FN + RIGHT arrow key is what changes the backlit keyboard to AUTO, ON, OFF. Sometimes when on AUTO it works correctly, and other times I could be in pitch black and the light doesn't come on and I have to manually select ON! Other times it works flawlessly. This seems to go hand in hand with the FN + LEFT for the ambient light sensor setting as well as the onscreen battery volume indicator--- at some times it works correctly, other times the on screen display is not shown when going volume up or down. Please advise.

3. The usb port on the left (looking at screen) top-most port, I believe that is for charging, even when the laptop is not up and running as long as the ac power is connected, right? Well for some reason, when plugging in my iPod, or any other device, it does not charge unless I am working on my computer. If I leave my computer for an hour or I turn it off or let it go in standby or whatever setting it does, the device stops charging and is unrecognized it seems...please help.

thanks for your expert guidance and suggestions!

 

1. Use a program such as RMClock to tell you the battery charge / discharge status. RMClock's battery info page will show the battery charge level and the charge / discharge power. If you used to get 4 hours on battery then that is a discharge rate of about 13,000mW. A fully charge 6-cell battery holds around 56,000mWh. What numbers do you see?

2. Make sure you have installed the latest version of Dell ControlPoint. I used to have similar problems but they have largely gone away.

3. You need to enable the powered USB port in the BIOS. Also, if you have something plugged in when you power down the computer then you need to pull it out and plug it in again. This is to indicate to the computer that you want to use the power even though the computer is off.

Why not? just swap the HDD's.

 

I don't know if it's an LED or not, but it's definitely an LCD. What did you expect? A CRT monitor with its huge tube?
