Latitude E6400 Owner's Lounge, Part 2

I find it strange that the DisplayPort to Dual Link DVI adaptor does not drive the 3007wfp, yet that same port (minus the adaptor) can drive the 3008wfp via DisplayPort. So there must be some limitation in the DualLink DVI adaptor?

 

remember my crushed laptop?
the problem solved.
so I changed the motherboard but fan didn't worked.
then I put a brick of ice under my laptop at a close distance(so it dont overheat).
Then updated the BIOS to v.A25 the problem was solved and fan began to work.
thanks everybody for help!

 

That's an interesting fix, but thanks for the update.

Yes. DVI and displayport are very different interfaces. Much of what a traditional graphics card does with regard to driving individual pixels is handeled on montor end with displayport. This requires the adaptor to have pretty sophisticated powers of conversion and designing with that high of a resolution would drive up the cost of the adaptor with little benefit to most users. Displayport was the major reason for the redesign that became the 3008wfp monitor. Displayport does not seem to have cought on outside of Dell and Apple though.

 

Alright, Dell Canada drop the battery price of the Latitude E6400.

Dell confirmed to me that if the E6410 battery (looking at the 9-cell 90Whr) is IF the battery the exact shape and size, where the connector is placed identically to the E6400 9-cell battery, it should work with the Latitude E6400 system.

In Canada the 9-cell E6400 battery (85WHr) is 155.99$, while the E6410 9-cell 90WHr E6410 battery is 210.99$

 

I'm sure that someone somewhere confirmed that the batteries were compatible. Maybe in the E6410 thread.

John

 

They are. I have a client who just got an E6510 and his battery worked on my E6400. I would guess the E series is going to be like the D series and until they move to the EXX20, it will look the same!

 

I'm sorry about these questions probably being answered already at some point but since i'm not a daily user and covering all of the threads and the 2 lounges will take ages. I have 2 issues atm.

1) I changed the included 80GB hitachi drive for a 500GB WD Scorpio blue and now the vent is now constantly on and audible in a moderately quiet room. I didn't have this problem with last drive and OS installion. Is this some sort of driver/windows issue, since I had to reinstall Windows or is this because of the change? Any hints on this?

2) I plan to buy a 3G WWAN card but i need UMTS900 and UMTS2100 supports. As I've heard Dell Wireless 5530/5540 don't support UMTS900 (prove me wrong if they do). Which card should I look for that would be compactible with E6400? (E: just to mention, yes my E6400 is prepped with antenna cables)

 

Did you clone the old HDD or reinstall Windows?

Both the Scorpio Blue and the recent Hitachi HDDs have similar power consumption and I don't think the HDD itself is the cause (but a useful indicator is the temperature of the left palm rest). If you reinstalled Windows then I suspect that you have some additional background tasks running that did not run previously. One way to see what is using the CPU in the background is to enable the CPU Time column on the process page of Task Manager. This shows the cumulative CPU usage by each process (select Show processes from all users). For example, currently I can see the System Idle process at 90 hours and ekrn.exe (part of NOD32 AV) at 3 hours.

Since the old HDD was damaged and hanged when certain sectors were accessed I installed a fresh copy.

Temperatures haven't changed much, the new drive is about the same, 37C atm with ambient about 26C i think. CPU and cores keep to about 41-43C when just browsing. When i looked at total CPU time the system idle was about 5:25 and the next process was dwm which had 3 mintues, then 5 more tasks which had between 1-3 minutes of cpu time.

I'm actually starting to think that this might be because of the hard drive itself. This is weird however since both the last one and the new one are 5400rpm and I couldn't hear the hitachi drive unless i put my ear right on to the palmrest, however I think it actually might be the drive that I'm hearing. If that's the case then i'm really dissapointed in WD. I'm going to doublecheck this with an external HDD dock

E: also the sound is 2type. First there is a hollow sound and then there's something that sounds like 2 parts moving against eachother. The new drive did show a weird sympton at first but I thought it was irrelevant when it just dissapeared. I made 2 parts on it, however after 3 days of using the second partition lost it's file system (partition was visible, but no file system on it), later after messing around it just appeared back. DST and smart on the drive show no worries.

EDIT2: Ok about the noise issues, I took out the WD drive and grapped my old hitachi and I started them up in my akasa HDD dock (it has no sound proofing) and when i put my ear next to the drive I could barely hear the hitachi but the WD was quite load. Not 3,5" 7,2k drive loud but compared to hitachi the difference was huge. Also i'm not getting the 2-sounded weird noise anymore.

Still looking for some info on the WWAN card though..
