Adding an external USB keyboard may not diagnose the keyboard fault. It does not isolate the keyboard as inserting earphones isolate speakers, rather piggy backs the laptop keyboard.
The only way to check the keyboard is to disconnect the keyboard cable. Take only a few minutes and you need small crosshead and flat screwdrivers. Follow the instructions in the service video.
Took me 5 days to find this out, my fault was the caps lock button was inverting capital and small letters, stopping the use of numbers and oddly it caused all files to be highlighted if only one was clicked.

I have Idealpad keyboard problem that is very weird, when it start, the keyboard doesn't work until on screen keyboard loaded, but after a while, the keyboard is down again. I tried everything, restored the system to the purchase status and uninstall the keyboard driver, but the problem is still there. Beg your help.

I got a G570 for Christmas. Not only is the keyboarding very slow to respond, so it won't let me type quickly, but it is doing very weird things like
Typing ? when striking k
Also 2 days in a row needed to reboot as when i clicked item on screen, then clicked another acted like I was holding down control key.
Any ideas for what is going on?

have similiar problem like yours
in my case, it always starts with some beeps,then "n" and "m" stop working and the most anonying thing is the space key, it prints "+" and launches some applications randomly
