Hey, all. I Have clean my fan in my aspire v3-471g. And complete the setup to turn on laptop. When I first boot, the only "A" isn't work at all, even when i in bios setup. I disassembly again to check the keyboard. now the esc, tab, capslock, shift, A and other left-top key doesn't work.
But i dont want to change the keyboard after I see the different between i assemble all the case of laptop and when the laptop is disassemble (only keyboard connected to motherboard).
When its in disassemble, my righ-arrow key, and Q key isn't work. but when i assemble all the case, right-arrow key, and Q key is working again.

    Try the following: Remove the lithium battery and press the power button for thirty seconds and turn on the notebook to test!
    If it still does not work, remove the lithium battery, open the notebook, and unplug the keyboard and mouse from the motherboard! Then disconnect the rtc battery and press the power button for thirty seconds! Then plug in the rtc, keyboard, and mouse connectors!

  • Is the keyboard cable connected correctly? Is there any damaged ribbon cable track?

    I Have check the bracket screw. And some screw is missing. I have move some of screw. and thats isn't problem. btw, my touchpad is not working when i disable nvidia graphics. where the problem? i need to fix this. please your help.
  • Do the following: Go to Device Manager and check if there are any drivers with problems! Then delete the keyboard and mouse driver, reboot and test! If it doesn't work, check in the BIOS if there is a Touchpad option and put in or advanced or basic! Check for a special key option and change the key to the function key and vice versa!

    I really don't understand. I try to install Standard PS/2 101/102 Keyboard, and my all the key is working perfect unless the shift key, but in the bios my esc, `,  a, caps lock, and shift key isn't work. this is the bios problem.
    and I don't know to remove the battery.
  • Just disconnect the motherboard wire!

  • I think this is no problem on the bios, but rather on the keyboard ribbon cable! However you can upgrade the bios of the notebook, but it will be at your own risk, because in case something goes wrong, your notebook will turn a brick: https://www.acer.com/ac/pt/BR/content/support-product/4075?b=1

    Ok! my keyboard now working again! I disconnect the wire of rtc battery, and i have wait for some hours then press and hold power button for 30 seconds, after that but some keys still doesnt work. I try install and remove the keyboard driver with other driver like 101/102, acer ergon, and HID Keyboard driver several times from device manager, then shift key work. I flash bios with the same version, and reset all configuration to default then reboot, but still same. I have frustating, and just working with the usb mouse in adobe illustrator. But, after some minutes, A keys, and all other keys is work perfectly! Thanks acer forum!
