nVIDIA GeForce 8400M G

Memory problem with nVIDIA GeForce  8400M G graphic card on Amilo Pa2548 , split screen on different pictures.
Any solution ?

RE: nVIDIA GeForce 8400M G

What kind of problem?
What have you tried so far?

Have you updated video card drives?

Gives something to work here, we are not mind readers.

RE: nVIDIA GeForce 8400M G

the problem begin from the start-up even i enter on bios.
the notebook book screen is always separated on 8 "small screen" .

There's no option (function key) that could be causing a change in output is there???

Take a picture of the screen with a camera, upload it to a photo sharing site, and put a link on here so we can see what's happening.   You're being very stingy with the details if you're trying to get it solved.

RE: nVIDIA GeForce 8400M G

8 small screens?  After some Googling, I found there seems to be some wide spread issues with certain models of HP laptops around that exhibit this 8 small screen behavior with certain Nvidia GPUs.

Most resolutions indicate the replacement of the motherboard. Or the GPU chip if removable.

Other than that, perhaps if your laptop is still under warranty, you can take it to a Fujitsu service center to get looked at.

Otherwise you may need to test with a different video card if at all possible.

The nVidia graphics chipsets in the 8xxx series have known issues that cause them to eventually deteriorate.  And since (to my knowledge) none of them are separate from the motherboards, only option is replacement.

I knew this when I was given a laptop a while back.  It had no issues at the time other than software, but it's a ticking time bomb.  Either one day it will burn up and die on me, or maybe I'll get lucky?  From what I've read about the issue, I think it's more just a matter of time.

In your case, time has run out, it seems.  Time to go hunting for a new motherboard or new laptop.  If you want to try to keep the same laptop, you could try searching to see if they made a model with a different video chipset.  On mine (Dell XPS M1530), some had the nvidia graphics, and some had intel.  The intel based ones had no such issues.  'Course, they also can't exactly play just any game you want, either.... but if you have an 8400 it won't be as big a loss as from my 8600GT.

RE: nVIDIA GeForce 8400M G

thnx a lot.
have anyone try to replace the graphics card nividia 8400M on notebook Amilo Pa2548 ?

RE: nVIDIA GeForce 8400M G

If the video card is NOT discrete (separate) from the motherboard, you cannot replace the video card without replacing the motherboard.

You have to verify this yourself.

If that's the case, it's likely a better idea to replace the laptop than to go for a new mobo.

RE: nVIDIA GeForce 8400M G

Yes, a while back Fujitsu-Siemens and other laptop manufacturers had problems with nVidia gfx.cards, in that they would overheat, and start failing... don't remember if it was the 7xxx or 8xxx range or both...

but you need to ask yourself, is it worth it to replace the card or just get a newer laptop, from the beginning...

and if you are out of luck, the card may be soldered so no replacing possible...

PS: nVidia GeForce 8400M go on eBay (Germany) for around €75 used...

RE: nVIDIA GeForce 8400M G

  Actually there are several shops. at least here in the US with reflow stations that will repair the system for less than 100.00 usd. They will also add copper shims and better heat management to keep this from happening again. The chip itself is rarely the problem. Here is a link to a place in the UK that can handle the reflow work.http://www.prlog.org/10554661-dell-nvidia-graphics-card-repair-same-day-bga-reflow-services.html

  Of course if the system board is available it is also an option, but if the reason for the overheating is not addressed it will happen again.

RE: nVIDIA GeForce 8400M G

What is "reflow"??   Yes, I could google it.  No, I'm not lazy.

RE: nVIDIA GeForce 8400M G

  Kind of a misleading statement, as really, they remove the chip, clean off all old solder, flux the heck out of it, and add these tiny balls of solder, then heat the whole thing up with a dark infrared station like this. http://www.dhgate.com/achi-ir-pro-sc-dark-infrared-bga-repair-system/r-ff8080812c2a1244012c40c6f28b7f05.html  and here is a really crappy video. http://current.com/groups/mobile/90159101_jovy-re-7500-usb-controlled-computer-dark-infrared-soldering-station-full-functions.htm

  Whatever you decide to do, don't use a hot air gun,or torch, and other things that will just destroy the motherboard.
