    Hello All;

    I just got in a Lenovo G770 Laptop yesterday for my Birthday.
    I really hate the BIOS, and not being able to do anything within it, as I do in my other systems.
    Could someone unlock this for me?

    (replace the DOT is the .)
    Here is the link to my BIOS (64 Bit)
    Here is the dump for my BIOS

    The BIOS have been updated to the current version, of which is the link above.

    The motherboard can handle 16Gb of RAM, however, the BIOS are setup for only 8Gb of RAM.
    Right now, I have 1 8Gb stick in one slot, and the other slot if empty.
    I read a post from 2 years ago, where you have to enable the BIOS to see all the installed memory, within the InsydeH20 BIOS, however, I am not given them luxuries at all.

    I also need to Enable hardware-v, as i am not given that option either.
    These BIOS, factory set, completely suck.
    I am used to being able to work in the BIOS and do what I need to do, this limitation is a joke.

    This is my original thread

    Thanks in advance for anyone's help on this issue.

    Thank you

    This worked

    Format USB Drive to Fat32
    Rename the downloadable file
    Copy the .bin file over to your usb fat32 drive.

    Follow instruction below.
    (In the last step, once you cut the system back on, you do not have to hold down the FN+B key the entire time.
    I never did get a first Beep. It took about 2 minutes for it to start beeping.
    Once the beeping starts, give it about 4 straight beeps.
    Unplug the cable, and pull the battery out.
    Count to 5
    Put the battery back in, and boot the system.
    Press F2 to get into the BIOS, and you should have everything that you need.)

    1. turn off the laptop
    2. Unplug the power cord.
    3. insert the flash drive
    4. press and hold Fn-B key combination
    5. while holding Fn-B, plug in the power cord
    6. still holding Fn-B, press Power button
    the computer will spin up the fan but the screen will remain black.
    If it finds the appropriate file, it'll beep again, read it in,
    and will start flashing the BIOS. Once it's completed flashing the BIOS,
    it will continuously beep, the power button will not respond, neither
    will any key combinations (Scared me at this point, thought i bricked my motherboard).
    I unplugged the laptop from the power, pulled the battery to kill the laptop.
    Once I put the battery back in, I hit the power button and it powered up and ran without issue.

    I am still playing around with the BIOS, I just did this last night.
    The system is running stable, and there are no issues so far.
    I was able to change my Dedicated Video Memory from 64mb to 128mb
    (The Video Card has nearly 2GB, to bad I am not given an option to go higher, but 128mb is better than the default 64mb)
    I am checking in on the Hardware VT right now, along with Memory.
    I have 16GB of memory in my system, and it only calls for 8GB.
    The BIOS now reads all memory accurately in both slots.
    Just not on the "Information" Tab, it still reads it improperly.

    OK, that should rap this one up.
