Latitude E6400 Owner's Lounge, Part 2

You're looking for the "Sleep" button, change it to hibernate.

It is worth noting that when you utilize hibernation mode, a portion of your hard drive is dedicated to the hibernation file. Generally it is the same amount of space as you have RAM, so if you have 4GB of RAM, ~4GB of HD is going to be unusable for you due to being reserved for the hibernation file. Hibernation has also been known to fragment your hard drive, so be sure to run defrag every once and a while and definitely shut down your computer every so often so it remains stable. Hibernation is a fine feature to use, but I figure its worth noting.

 

It appears that Windows does some compression. My hibernation file is sitting at about 3.1GB although the RAM is 4GB (and I'm running W7-64).

I would not expect hibernation to cause disk fragmentation problems. That is more likely to result from letting Windows dynamically resize the paging file.

I finally got sound to work through my Displayport to HDMI, It sounds great but I still have to disable the laptop speakers for it to work.


I defaulted all the way back to the Windows 7 drivers for the sound card (as I stated earlier).

I had seen in a post for another dell laptop model with someone asking a similar question about the sound over the displayport. In that post one of the responses said that you needed to use the video card driver that Dell provides in the Drivers and Downloads section for your laptop model to get the video and sound to work. So I decided to try it for the E6400.

1. I went and downloaded the driver from Dell's website
2. Removed and deleted my current NVIDIA driver
3. Installed the Dell Version (nVidia_multi-device_A09_R256859.exe) and now the sound works.

After getting it to work I tried to install the latest drivers from NVIDIA's site (257.15_notebook_winvista_win7_64bit_international_beta.exe), and the sound stopped working again, so I rolled the driver back to the Dell version and it worked again.

The only thing that frustrates me still is I have to go into the sound settings and disable the speakers to get the S/PDIF to work.

In the end I am not sure if the sound card driver was messing up or the video card driver. But defaulting to the Win 7 sound driver, and using Dell's version for the Video card eventually produce sound.

If anyone has any thoughts please let me know. Thank you all for your help.

 

Good to hear that you got it working. I have to disable my speakers each time I wish to listen through the hdmi audio as well, I haven't heard of a way to get around this at this point. Another design flaw in these laptops it seems.

 

has anybody installed linux? which distribution do you suggest and why?

 

I was looking to solve my problem and found this. You might be interested to study these topics first.

 

Hello it's me again.
I just changed the motherboard.
Everything works great besides Processor Heatsink fan. Does anyone knows what king of issue it could be: updating BIOS or buying a new Processor Heatsink (which I guess not because while powering on without RAM Processor Heatsink fan works great for a second or two).
please help.

update bios, if fan doesn't work at all it might be disconnected.
