    Hi all!!!
    I have been using this Acer since 2005. It was my first computer. The last 2 years it started gradually behaving really slow and many times not even moving. However I kept it, while using other laptop for my job.
    At the moment I have decided to try to save that laptop in any possible way.
    I want to ask you if you have any idea what these green spots might be.
    They cover huge part of the screen and I had to change light settings to very bright in order to be able to see somehow what is going on on screen.

    Thanks in advance.

    Hi buzzer and welcome to NBR.

    How do they look like- how big they are?
    Are those stuck sub-pixels or something bigger than that?

    Also what model exactly do you have?

    Most likely the backlight spreader is damaged. A panel replacement may be in order.

    The (normally) white plastic backing of the display panel, which distributes light from the CCFL tube at the bottom of the panel to all of the screen; it is likely discolored, resulting in spots.

    Could be a damaged GPU, they might be artifacts. A picture of the spots would help us give you a definitive answer.

    artifacts are usually random. if it was artifacting that bad they'd be pretty aggressive with BSODs.

    Here is a picture of the screen. Imagine that I have set brightness to verz light so that the spots are not so aggressive

    So the spots are not stationary, then.

    This looks like the LVDS cable, or maybe VRAM.

    So, is that something I can easily fix or it needs a lot of money and time?

    If it's the LVDS cable, then it is relatively cheap.

    If it is the GPU or VRAM, and this is an MXM Acer, then an MXM replacement may help. However, if the GPU is soldered on the motherboard, or if this is an Intel GMA system, then it is basically unfixable (requires a new motherboard).

    Thanks for all the responses everybody. (I don't understand most of it but I got a picture)
    Possibly last question: I guess for a real diagnosis I shall visit a specialist right? Or is it something that you (or somebody else) could guide me through it and I can manually open laptop and see what is going on?

    Thanks in advance for all your help and interest

    I would say if you are not experienced with disassembling laptops, then seek a specialist.
