Laptop keyboard is acting crazy
Hi guys, my keyboard is constantly turning on and off the shift key on its own in an unpredictable manner. It makes typing extremely annoying and interferes with operating windows on my laptop.
Not sure if it's the laptop hardware itself is the issue or something else like a virus etc, because the problem is replicated using the on-screen keyboard and external keyboard as well.
I've ran an Microsoft Security Essentials antivirus scan and everything seems to be OK. Any help or advice will be highly appreciated. The laptop is a LEnovo Thinkpad E420, thanks.
