Latitude E6400 Owner's Lounge

I did find new Intel Matrix drivers, where compared to Windows drivers, I had increase battery life (a little) and had Vista boot super ultra fast (5 bars passing on my 5200RPM fully defragmented HDD), and of course latency reduced and shows no signs of problem. Oh and the SmartCard card reader I THINK, I don't remember as well as the sound card drivers too (just some bug fixes). I think that is about it.

 

This would be more useful if you did provide specifics...

 

make it clear you are highly competent, and make them do what you want. i wish i felt comfortable providing a method, but i bet you can work it out.

 

I notice that you keep saying 5200 pm HDD. Is that an overclocked version of a 4200 rpm drive, or underclocked version of a 5400 or a 7200 rpm drive?

 

5400RPM... I know I make this mistake... I don't know why I do it and don't realize it. I guess it comes after saying 7200RPM to many times.

 

Aside from the latest Intel matrix Storage, there's the A11 version of Dell ControlPoint System Manager.

dell just started offering the intel 5150 wifi/wimax pci-e mini half card as an option in the studio 15,17 and xps 16. do you think our e6400's could use this, or do we not have the correct antennae installed? not that most people have wimax in their area anyway

 

Has anybody noticed this behaviour?

Out of the blue the main vent of the E6400 becomes very noisy.
No programs that could stress CPU are running.

When I check "task manager" - I see that CPU is at 50% (normal at that load would be 5-10%) and the most CPU consuming task is 'winlogon.exe'.

When I lock the computer and unlock -the CPU load goes back to normal.

I have experienced this behaviour 3-5 times over last 6 months. Can't remember any major changes prior to problem occurence.

I don't know if it's relevant, but I use fingerprint to log in (with preboot auth.).

 

1. A chipset temperature of 50C will cause the fan to run fast. This can be caused by some operating conditions, eg memory-intensive tasks, that do not fully stress the CPU. Use HWMonitor to look at the temperatures next time this happens.

2. What BIOS version are you running? I'm running A11. A12 had an effect that I didn't like, although I can't remember what it was without digging back through this thread.

Installed my intel 5300 wifi card last night. Very happy with the signal strength and speed. It connects at full 54Mbps and I can stream 720p h264 mkv files with no stuttering. But for some reason it won't connect at 802.11n. I even set my router to N only and then the card won't be able to connect at all.. I made sure they both used the same encryption so it's pretty weird. could be a dd-wrt bug on my router I guess :| just bid on a new dual band router on ebay
