Hello,

Have you updated your system BIOS with the latest download from Aspire?

This upgrade is particularly important if you have updated your Vista with service pack one or two (which may have been done automatically depending on your Windows update setting).

To upgrade your system BIOS download the latest version from the link below-
http://support.acer-euro.com/drivers/notebook/as_5920.html

simply run the file that is provided in the zipped form in order to update your system bios which should resolve this issue unless it is hardware related which is usually not the case on this laptop.

Acer Laptop Screen Flickers & Jumps


Hello,



Please connect the laptop to an external monitor. If no flickering on monitor screen, from my previous experience, this is more likely loose connection of video cable connected to the LCD. So talk to Acer support again and require the replacement of LCD.

How to solve Flickering problem of LCD


I have had the same problem,
I found it was my power supply transformer (part of power lead).
Some transformers may be faulty, or replacement transformer may not provide a voltage stable enough for the LCD.
Also check the wiring in your plug.
Safest option is, buy a genuine Acer supply transformer with plug lead from Acer.

Hope this helps (please rate my advice)

How to solve Flickering problem of LCD


I have an Acer 5920G that's only 3 months old and it's screen started flickering. Updating or rolling back the graphics card driver made no difference. I then updated the Chipset driver from the Acer website. It hasn't flickered since!
The graphics info has to pass through the chipset so I assume the driver wasn't up to the job.

Flickering LCD


yeah actually i can but if i didn't know any better i would swear you are dealing with HP. But I honestly think that the issue is your graphics card is not getting enough power. It can actually be a couple things bu i would start there. If that is not the problem start looking at the ram. If the ram starts to go bad or has a power issue it will mess up your display also. I am glad they replaced the processor. that would be the next place and from there it would almost have to be the power supply. One thing you have to make sure of however is that they can reproduce the problem when they have the laptop.
