    Hi all, :hi2:

    I need help.... :(

    2-3 Years ago, I bought may Acer Laptop Aspire 4750G.
    Specs:
    - intel core i5-2410M 2.3 GHz, turbo boost up to 2.9 GHz
    - Nvidia GeForce GT 540M 2 GB, intel HD graphics family
    - Memmory ram 8 GB.
    - Windows 7 Home premium Service pack 1 64-bit.
    - Nvidia optimus

    I have been playing old games. But recently I found out that it may be the whole 2-3 years I use my laptop, it never use the GeForce. That may explain some lags when playing certain games. With newer games that provides benchmark, the report always shows that they are testing it using intel HD Graphics family. Never use the GeForce.

    New games always lag or not working at all. The Nvidia optimus didn't switch to GeForce in hard/heavy games. I don't know why.

    Numerous info scattered in websites/forums. Suggest maximum power or manual right click "run with graphic card" or change the GeForce as default in nvidia control center.

    None is work.
    - I plugged my laptop on AC power, with maximum power settings
    - Changed global settings in nvidia control panel to use the GeForce as preferred graphic card
    - Right click game and choose run with graphic processor - Nvidia --> Doesn't work.
    - Regardless of all heavy games I run, Nvidia GPU activity: none
    - DxDiag shows intel HD not GeForce.
    - My GeForce is up to date.
    - Disable Intel HD graphic card will give me black screen, no display.

    Basically I don't know how to activate the GeForce manually or automatically. Start to wondering is the nvidia optomus is there? How to know if I even have this technology, regardless the sticker on my laptop and the 2 nvidia icons (green logo - control panel and dark box with dots, showing Nvidia GPU activity)

    My BIOS seem to be an old version, No option to boot my windows from bios with Nvidia.

    So my question is, how can I use my GeForce?
    The warranty is over, I didn't know my laptop didn't use the nvidia card this whole time.

    Should I update my Bios? Which makes me asking the second question.
    Which one I should install? What should I do before intall it?

    My BIOS is
    BIOS Version/Date : Phoenix Technologies Ltd. V1.23, 4/28/2011
    SMBIOS Version 2.6

    I tried to look in:
    Acer | Download

    And it confuses me. Why with the latest date, the version number is getting smaller.

    Acer BIOS 1.24 - 7.8 MB - 2012/12/26
    Acer BIOS 2.19 - 8.0 MB - 2012/04/30
    Acer BIOS 2.17 - 7.9 MB - 2012/04/10

    Do I have to install all?

    Thank you for your time and your help.

    I am also having the same problem and I have tried the same solutions with no success. Has anyone else managed to get around this optimus problem for old games?
