The story is:



I put on hibernate my laptop (Amilo Xi2428) . When i turned on again the computer the screen was completely gray and it was not responding to anything, so i did shut it down.

Please note, that before putting to hibernate i did not install any kind of software, neither did touch anything on the hardware


When i started it, before it did even boot it started to show the lines. I entered the bios, the lines were there plus i was seeing different characters all around my screen. I tried to boot on windows or on linux, but i could not. The laptop was failing to boot on any OS, same happened also with a live CD of Kubuntu.


After leaving it for many hours to cool down, it finally started again without any problem. 20 minutes later i got again a gray screen and the laptop freezed. After trying to start it again it failed.


Further information: Software that read GPU information show the clock speed at zero. Furthermore the GPU temp is about 65c while my CPU at 40. Something tells me that there is something going on with the VGA, the question is what can i try to see if i am able to resolve the problem ?

I don't think it is the screen. I am almost sure it has to do with the GPU.

I added a fan at the bottom of the laptop to keep it cool and the problem disappeared. Once i turned of the fan the problem started again .

Just in case i did a BIOS upgrade (although it did not seem to fix anything).

On normal use i see temps high as 75 now (without the extra fan) .

The question is if the GPU is damaged already by the heat or my problem can be fixed by replacing the cooling system instead of the whole mainboard.

As i do not play games , i also thing of decreasing the GPU clock.

Any other suggestions/ideas are welcome.

I am almost sure now it is the onboard VGA.
I removed the external fan and run a graphic test. Once the GPU reached 75c the laptop froze and the monitor turned black.

75c does not sound so extreme to me. I saw many graphic cards running at that temp under full load.

So, can i consider the VGA as damaged or the cooling system ?

I found some really important information for some people that have the same problem. It looks that nvidia can make a free repair.

A NVIDIA chip failure may take place due to a weak die/packaging material set. The solder can become too dry because of the regular temperature fluxes of the computer, and will therefore stop making contact to the motherboard. Fujitsu is just one among many computer brands that use NVIDIA chip technology and have experienced malfunctions because of the graphics processors and chipsets generating heat.

The ways by which you can tell that your NVIDIA graphics chip in your Fujitsu may be failing include:

Multiple images
Random or unusual characters on the screen
Horizontal, vertical or jagged lines appear on the screen
Video freezes
Video is distorted or scrambled
Flickering action
Random rebooting or shut down
Blank video or screen

I gave a phone call on the above phone number. I was told that this is just a repair shop and they cannot do anything about it.

Furthermore i was told that i should better contact with my manufacturer.

I don't get it, why is their phone number there listed then
February 27, 2012 8:43:23 AM

A reply from info@creativeit.tv was not was i was expecting. I was told of 135 UK pounds for the service.

I thought that would be something like a recall from nVidia, but apparently it is not

Hi :) 

I own a lappy repair company in the UK...

That company are PRETENDING to be associated with Fujitsu....they are NOT....

IF you have the graphics refloat problem and I repeat IF....

Most companies like mine charge around £80 to £100 to strip the motherboard out, then refloat the chip and then reassemble the lappy...

BUT !!!!!!!!!!!

I warn you as we warn all our customers...the refloat might last 6 months or SIX MINUTES......

We REALLY REALLY try and deter our customers from having this refloat repair done....

Because of its EXTREMELY high failure rate...


All the best Brett :)
