    Hi, I have an Acer 5520 Laptop with a 15.4" display and Nvidia GeForce 9300M G graphics chip. It is about 22 months old

    Recently the built in LCD monitor failed but it still works via an external monitor. When it boots there is a brief flash of light on the LCD but no display at all. It all works perfectly on the external monitor from BIOS display through to normal use.

    However, around the same time we tried to upload a later Nvidia driver and it won't work now with any Nvidia driver at all. It's been re-formatted and we have tried a variety of different Nvidia and OEM drivers under both Vista 32 and Windows 7 64. It works fine as a VGA adapter but locks on boot up whenever we try to put on any kind of Nvidia driver. It's strange that it works perfectly with a vga adapter but when we try to update this in win7, it suggests the latest Nvidia driver.

    I read on some forums that the Nvidia chip can come loose on the mobo due to dry solder and we heated this up, but it didn't make any difference, apart from scorching the case!

    I am assuming the next step is to fit a new LCD panel and motherboard to fix both issues. Does anyone have any advice? It seems strange that 2 graphics related issues appeared possibly at the same time.

    Thanks in advance for any replies.

    It might be like You saying, problems with cracking solder joints under the gpu. I know, that this was a common issue on GeForce Go 6100/6150 GPUs. And about the screen, it's probably ok because ther're different routs used by gpu to put display on internal and external monitor. Because thera no display on internal lcd that doesent mean that it's broken, it probably mean that ther;re problems with solder on the pads responsible for rout on internal lcd. Probably proffesional bga reballing and resoldering gpu chip would solve the problem. In other case find new motherboard.

    Hi,

    Do you know what the motherboard is and whetaher:
    * The CPU is soldered to it or swappable?
    * If the mobo will take a plus in GPU?

    CPu is swappable as the GPU is since you are using 5520 G model...

    Cheers
