How to use keyboad Asus Transformer TP550L because I don't know green key

unplug battery and use power cord see if it works then.

Blow the keyboad with air blower. try to reinstall all drivers and if not. you have to attached external keyboad temporarily while fixing the issue.

I don't think there is a way to adjust the keyboard sensitivity. I know of ways to adjust the keyboards Repeat rate, which is when the keys appear after you press them. Try that and see if that is what you're looking for. Click Start/Control Panel and look for your keyboard in the control panel.

Change the keyboard location and layout. It is in the control panel of your operating system.

ASUS usually uses the DEL key to acess the Bios.

The problem is most likely that the default program installed by the manufacturer has been stopped or didn't start try restarting your computer and if that doesn't work:

-Try restoring your computer to an earlier time using the SYSTEM RESTORE utility in the Control Panel.
-Most of the time your computer should automatically create a restore point when you install something on your computer.
-You will need to restore your computer to a time when you know that the keys were working.
-Then restart the computer again

Hope it helps
