Hi. After updating my laptop BIOS from initial version v1.x to 2.18 number pad does not work anymore.
"PageDown" key works as "Home" key, "PageUp" key work as "PageDown" key and "Home" key works as "PageUp" key.
Other keys on keyboard are OK.
I'm sure the problem is not OS related.
By pressing Fn+F11 a number pad enables on letter keys like some laptops without any physical number pad.
I updated BIOS because need of UEFI.
And in BIOS download page under v2.18 mentioned this "Update KBC to v1.23". is it related to the problem?
Anybody have any ideas?

Thanks.

    Hi,
    Go to BIOS screen, move to Main tab, press F9 button, press F10 to save and exit and see whether it helps.

    Are you using a hacked/modded BIOS?
    I'm not an Acer employee.
  • In addition to the suggestions of my colleagues, try turning off the laptop, disconnecting the battery and also pressing the power for 30 seconds. Also try installing the launch manager: https://global-download.acer.com/GDFiles/Application/LaunchManager/LaunchManager_Dritek_5.2.1_W8x64U_A.zip?acerid=634932381235046349&Step1=ULTRA-THIN&Step2=ASPIRE&Step3=ASPIRE V5-571G&OS=8U1&LC=pt&BC=ACER&SC=PA_3

    I upgraded BIOS from 1.x to 2.11 with a dump BIOS file because normally upgrade from 1.x to 2.x is not possible.
    Then upgraded normally to official 2.18 version which is latest version on product support web page.
    It's not modded or hacked BIOS.

    Hi,
    Did you also press NumLk key?
    Sure. Nothing happens.
    I tested keyboard functions with this online keyboard tester.
    https://www.keyboardtester.com/tester.html

    On pressing Physical "NumLock" key there is no action and it detect nothing.
    And by pressing Fn+F11 it detects "NumLock" pressed.
    And some other keys I mentioned in first post, work displaced too.

    Anyone have information about KBC?
    What is it Exactly?
    In 2.18 version it is Updated and I think this is the problem. Am I wrong?

    Any way to downgrade BIOS to 1.x?

    I'm using Win 10. I also test on Ubuntu Linux. The problem exists.
    I said I think it's not OS related before.
  • Does this model have a function called function key behavior in the bios?

    No. The bios menu is so simple. Not so many options.
  • Have you ever tried to just disconnect the rtc battery and reconnect it again? Also, have you tried to disconnect the keyboard?

    Yes. I changed the Battery with a new one. Also change the keyboard because one of the keys was broken.
    But the problem is for both old and new keyboard.
    I'm gonna try changing bios chip with a new one cause I didn't find a solution to downgrade.
    Now looking for a proper bios dump file to program the chip.
    Wish me luck :)
  • But the procedure may vary, depending on the model.
