    @JackE not in that session. after waking up from sleep or restating the laptop it turns on for 30 secs and then turns off until i put it into sleep and wake it up or restart the laptop.

  • Is there a function similar to that in the bios?

    Does the problem occur when you connect the power adapter?

    Try pressing Ctrl+S in BIOS Main tab to see if more options appear. If not, what BIOS version number do you have? Jack E/NJ

    unfortunately no . but my unit was manufactured in June '18 . If that helps. 
  • Does this problem occur when using the notebook on battery power or does it also occur when connecting the power adapter? What happens when you reset the battery?
    Have you checked this cable?

    Do you recall approximately when you updated the BIOS to v1.08? Jack E/NJ

  • Your model has a function called function key behavior in the bios. Try changing this function and then press fn + f9, just f9 or alt + f9, as I think the key that turns the backlitght on is f9.

    Yes yes I do know that. Function key behavior is set to media keys. 
    The keyboard backlight can be turned on and off with in those 30 secs. but once its turned off after that time period it can't be turned back on until the device is rebooted . It like the timeout function which i have in my other laptop. but this does not have such settings. i wonder how this happens

    I downloaded the zip file on april 02 2020. I downloaded and installed the driver to fix this issue in the first place. But it didn't do any good. The problem was there before the update only.

    OK. Probably related to a Win10 update, the restore point for which is probably also long gone. You should check it anyway. Open ControlPanel. Search 'restore point'. Click 'create a restore point'. If the box that pops up shows SystemProtection is turned on, then click 'system restore' button. Click 'next'. See if there's a Win10 update restore point created just before 4/2. Probably been wiped already. Jack E/NJ

  • Is it possible that the acer care center and acer quick access are interfering with the keyboard functions after installing the 2004 version of windows?
