I am unclear on what your problem is there? Are the characters you are typing on the screen being displayed too slowly?
That's mean I can't type 3 or above characters in a sec. Example like I want type 'qwe' in a second but will came out 'qw' or 'qe', can not came out what I typed.
ok then ... sounds like you might have a key stuck down ... clean the keypad and tap each key several times ... do this with it powered down. When you power it up make sure all of the keys work.
Another thing to check might be that the laptop is currently running the cpu at maximum ... slowing down the response rate of the keyboard.
Hit CTRL ALT DEL and run Task Manager ... hit the third tab across the top called "Performance" and see how much your CPU is loaded up ... if it is hovering around 100% all of the time then you might have your problem identified.

Check for malware and viruses.
My CPU rate 5% 0.81GHz, cause i just bought this laptop few days ago.
I have no idea how to fix it, maybe i should bring it to acer service center to fix it.
Ok ... new laptop ... def take it back in ... you paid hard earned cash ... expect good service. ACER are usually pretty good. I think we have an ACER rep on the forums ... I will check and see.
I have a similar problem, also don't know how to fix it. Just bought it yesterday. And it is interesting tha on some key combination it write all three letters but on some just two letters.
Have you found a solution to this?
