  • 1. No sound on my Dell. BIOS probs?
    OK, this is one of those probs I had tried for hours to fix, but have to put my hand up for help now. I have a Dell Latitude, CP M233XT with W2000 Pro successfully installed on it, except for one problem - it wont reconise my sound card. I have tried every Windows option that is available, with no success whatsoever. On a separate drive with W98 on it, the sound works fine, so I don't think it's hardware as such. Someone suggested that perhaps I need to update the BIOS, which is all good and well, except whenever I search for BIOS upgrades on Google, I get nowhere. If I search Dell.com, all they want to do is sell me stuff. Am I on the right track, and where do I get BIOS upgrades if that really is the next thing I should try? --- DFM

  • 3. Averatec 3120V laptop keyboard problem
    I purchased a Averatec 3120V laptop from Bestbuy. During the past few weeks when I press most keys on the keyboard the wrong letter appears on the screen when I reboot the problem goes away. This is an intermittent problem. Does anyone have any ideas what may be wrong. Thanks Dave
  • 4. ATI Mobility Radeon 9000 and WinXP Home
    Im running quite a high spec laptop, which I recently had to restore the system on. Problem is, every time I try to play any kind of game that requires a 3D card, windows gives me the blue screen of death after a few minutes play. The laptop restarts itself too fast to read the whole messege, but i notice that half the time the messege is "bad_pool_cleaner" or something similar. And when I send the error report to Microsoft, they tell me its a bad device driver. Yet I think I've installed the most recent drivers for my laptop (I haven't been able to find any drivers released after the end of July this year, so I'm assuming theyre the most up to date), and I still get the blue screen. Does anyone know why I'm still getting the blue screen? And more importantly, does anyone know how to fix this problem? Or is it going to be a restore the system job again?
  • 5. IBM T40: Possible to upgrade to Radeon 9600?
    Is this just a question of taking out the 7500 and putting in the 9600, just like a desktop?? I want to know if I can upgrade, if so how & what to buy..

Dell Inspiron 8100 Flickering video

Postby bdaoust » Thu, 09 Mar 2006 13:41:54 GMT

My father has a Dell Inspiron 8100 that has a video problem.

This Dell has the ATI Radeon 7500 Mobility card.

At first, the problem was that sometimes on the desktop there were
vertical lines and "boxes" around the mouse.  Wasn't bad and only
happened at certain times.

Now, the video sometimes is completely distorted with horizontial,
vertical, wavy lines.  Sometimes you can even read the scree.  Almost
looks like when you set a resolution that a monitor can't handle.

Again, this is random and sometimes it's fine.

I thought it was a video card problem, but elimindated that fact today.
 I reloaded the OS and updated the driver (the one from Dell).  The
video issue is also happening at the Dell logo screen on powerup, which
I believe elimindates the idea its a video driver issue.  And yes, it
also occurs on an external monitor, thus eliminating that its a LCD
issue or flex cable issue.  Right?

So I'm guessing it's a problem with the video card itself.  But why
would sometimes it be totatlly fine for hours or days?  I even tried
different power outlets to eliminate "noise" in the power lines.

Any ideas?  Things to try?

Thanks,
Brian

I've got the same problem but I have an Nvidia card.


Yep, been there. Also, when I make a new screen selection it goes
black for a sec and then changes. In those "boxes" you can see the
screen below that on the monitor.
 

Like you I thought it was the card, but I could not isolate a problem.
I'm beginning to wonder if it has soething to do with the memory
upgrade I made about six months ago,

Did you rule out the video card?

I have exactly the same problem with my inspiron 8100.  I had i
checked out by a laptop repair technician, he advised it was th
videocard (on the motherboard) and not worth fixing as it would cos
about A$800

I have however found other sites which may be of use to you see lin
 http://www.**--****.com/ 

I suspect it can be fxed at home with some simple directions and 
replacement video card

It would be interesting to see if others have had any luck

I'm having the same issue with my 8100. I have the radeon 7500. I hav
reinstalled the vedo driver to no avail. I removed the four keyboar
screws and found that the video card removes easily after removin
its 3 screws and the attached screen cable. I put everything bac
together and the problem did not go away. It wasn't caused by a loos
cable. I think if I can find a good deal on the video card I'll buy 
replacement

Good Luck

Let me know if that works out for you.

Update:  My father noticed that if he doesnt turn off the laptop, but
rather puts it in suspend mode, its fine!

Once he shuts down and reboots though, the wavy/crazy lines come up.
He then needs to reboot several times until the wavy lines arent
present.  

Strange?!?

2.Inspiron 8100 Video Question

Guys,

I have an Inspiron 8100 with an ATI Mobility Radeon 7500 (64meg) video 
card.  Last night the video started acting flaky (distorted / random 
lines in the video display, etc.).  I've narrowed the problem down to a 
bad video card and plan on replacing the card myself.

I've saw a new 7500 ATI 64meg Mobility Radeon card on EBay for $80.  The 
description states it is a new card for an Inspiron 5100. My question is 
- will the ATI card for a 5100 fit into a 8100??

BTW, if anyone has another source of video cards for the 8100 besides 
EBay let me know.

Thanks in advance,

Bob

3.Help with RAM for Dell Inspiron 8100

I'm trying to sort out RAM upgrades for an Inspiron 8100.  I have a single
SODIMM (256 MB), and would like to add one, and find that I have some
confusion concerning what will fit.  The SODIMM in the machine now is an
Infineon, PC133, CL3, 32Mx64 DIMM.  I find that there are many kinds of chips
that appear to meet those specifications, but that they have widely differing
prices.  Here are 2 specific questions: (1) Do I need a 32Mx64 DIMM, or can I
also use a 16Mx16?  (2) I have seen SODIMMs with the FRU #19K4655, and some
claim compatibility with the Inspiron; does anyone have first-hand knowledge
of whether they will work in the Inspiron 8100?

I would appreciate answers to those 2 specific questions (or pointers to where
I can find answers), as well as any learned treatises on SODIMMs for laptops.

Thanks in advance.
