ChaniduLashane2007

Hi guys my laptop is Acer Aspire System Model Aspire F5-572G
And before my keyboards all keys worked

I have reset and cleared everything and made a new window 10 home installation and now my keyboards all keys are working but like 4 keys with dual symbols only type the default symbol that one which should type with shift is not typing

Currently I can't type 1 Round Bracket -) ,1 square bracket - {, underscore- _ & question mark-?

Please help to fix this
Microsoft said all windows settings are fine and to replace those keys

Do I have to replace keys or is there any way to fix this?

For the Acer Aspire F5-572G, if keys with dual symbols aren't working, it's likely due to the Fn key being locked or a driver issue. Try toggling the Fn key lock (usually by pressing Fn + Esc or Fn + Num Lock) or updating/reinstalling the keyboard driver in Device Manager. If problems persist, consider a system restart or troubleshooting the keyboard in Safe Mode.

Here's a more detailed breakdown:
1. Check the Fn Key Lock:
Many Acer laptops have a function key (Fn) that needs to be toggled to access the secondary symbols on keys.
Try pressing Fn + Esc: This is a common combination to toggle the Fn lock.
Try pressing Fn + Num Lock/NumLk: Another option to disable the numeric key and return to the letter key.
Check for an Fn lock key: Some keyboards have a dedicated Fn Lock key, which you may need to press.
2. Update/Reinstall Keyboard Drivers:
Open Device Manager: Search for it in the Windows search bar.
Expand "Keyboards": Find your keyboard device (usually listed as "Standard PS/2 Keyboard").
Uninstall the driver: Right-click on the keyboard device and select "Uninstall device".
Restart your computer: Windows will attempt to reinstall the driver automatically.
3. Troubleshoot in Safe Mode:
Boot into Safe Mode: This allows you to see if the issue is caused by a software conflict.
See if the problem is resolved: If the keys work in Safe Mode, it suggests a software conflict.
4. Other Potential Solutions:
Restart your computer: A simple restart can resolve many minor issues.
Check for stuck keys: Inspect the keys for any physical obstructions.
Try an external keyboard: Connect an external keyboard to see if the problem is with the laptop's keyboard itself.
Consider a system reset: As a last resort, you can try resetting your system to factory settings.
