Dell Inspiron 6400 / e1505 big problem with switching to battery, please help!

Hello,

I have had this e1505 since June, and everything was fine, but todaay I was going to take it with me to another room, and pulled out the power cord like usual, and it didnt even though I saw it switch to battery a second later the screen turned off and the whole thing froze. I had to hold power button to turn it off, and pluging power cable back in didnt help.

I restarted, tried again and it did the same thing. I'm running windows xp sp2, and it does it in windows, during the bootup if power goes out everything is fine, but in windows it just stops like that and screen goes black.

Any ideas? Please help!

 

ok, I seem to have located the problem, its the newest omega drivers, 38.291 that were causing the screen to go black and the whole machine freeze when switching to battery in windos. I rolled back to 38.252, and it works fine now.

 

Im having the same probelm.
Pretty much exactly the same problem initially. Irealised that most of the time when the screen goes black, its not the laptop that shuts down, its just the screen that goes off.

There is another thread in this section describing a flickering screen.

 

if u have omeage drives 38.291 or maybe 273 try installing 252, those are the most stable i find, it helped me.

 

You fixed it !?!?!?
I will be curious to know if it solved it for "good"
The problems I have been having with this model with the screen going black are very intermitent.... my laptop can be fine for days and then start messing up again.

Can you keep me posted ?

 

well yeh, my screen doesnt go black anymore when switching to battery, it seems like latest omega drivers, or maybe even catalyst drivers (those are for your videocard) were causing that for me. its fine now when i rolled back to an older version of those drivers.

 

so if I am having this problem......what do I do? I have the up to date dell drivers.

 

how do you do that??? "roll back" ?

 

alexkolb1 im having the same trouble that had....how do u perfrom the roll back .....where can i find the old omega drivers....

PLEASE HELP!!!! im tired of this problem

 

there is an archive section on the Omega website...

 

here what u must do to prevent a freezing black screen.

1. Before unplugging your laptop, close the LCD lid.
2. Wait 2 sec for the screen to turn off.
3. Unplug ur laptop
4. Open the lid, and resume ur work.

When the screen it turned off (not black screen) ur system wont freeze. I also recommend using Dell official drivers.

 

Never had a laptop that needed such an elaborate procedure before?

What is Dell doing late at night in Texas? Looking for exciting new ways to mess things up?

 

has any one else tried to roll back omega drivers.....has it actually worked?
The dell tech support guys have no clue they say they have never heard of this problem ...is this a hardware defect of some sort?

thanx

 

any body still expiriencing probs?

 

I have reproduced and isolated this problem. The problem is related to the version of .NET that you installed. The ATI A3 drivers appear to work best with 1.1 of the MS .net framework. I think 2.0 and 3.0 break it, unless you have service packs applied.

The way to fix this problem is to go add-remove programs and uninstall your current .net framework. Then download and install the 1.1 redistributable from Microsoft.

the problem is not solved, it will come back randomly, and it seems its a OS problem not drivers, because I updated to Vista a month ago and I have never had this problem. I uplugged it many many times as I always I go mobile, and I did not face any black screen or screen flickering...

 

Strange. I was sure it was hardware after I rebuilt the machine and had the same problem. But then I replace the vid card, motherboard, and finally gave up, until I tried my HD in another e1505. I was shocked to discover that the new machine had the same problem as my old, I knew it had to be related to the OS build and most like the ATI drivers. So I played around with power management and the .NET framework that the ATI drivers require. Finally I found the solution about of downgrading to 1.1. I’d do a fresh install.

 

Going to try the .Net Frame 1.1 I think you have found the problem Slacka. I had the same problem with my 630m Both have ATI videocards....it bugs me like crazy will report my findings

 

noppeeee
froze when i pulled the power...... going to try the omega

 

Not for me...

Anyway to fix this... here is what I tried:

I use Omega driver.
Then after all done I restarted my laptop
When its back, right click on the desktop and go to properties.
Then Go to Settings -> Advanced
Click on tab Powerplay then just untick that one.

That fix my laptop 100%.

 

I'm facing the same problem with my Inspiron 6400. Can anyone please tell me
1.how do i find out version for the omega drivers installed
2.from where do i get the older or newwer vrsion of drivers that will solve this problem
3. how do i do the rollaback ..
I'm new with laptops and this one is my first so want to safe...with anything i do with my laptop....
thanx
