Linux (CentOS, Red Hat, Ubuntu) operating systems can't recognize my laptop keyboard, and I'm unable to work with it any more.

It had been fine but I don't know what's happened to it now. Note that it works correctly in Windows.

Any ideas what might be wrong and how I can fix it?

This question came from our site for system and network administrators.

Try starting the laptop without the battery.

It appears that 1510 series had lot's of issues when the battery is bad.
Mine, sometimes, refuses to initialize the keyboard in opensuse. I have to hit ESC before X is started.

I found it.

I pass this command to kernel when coming up:

linux i8042.reset

It's cause to run keyboard for a while. After each reset you should type it.

I also read somewhere else that by changing /boot/grub/menu.lst you can do it for all the time.

Find this line and add ro i8042.reset to it:

\# kopt=root=UUID=c10a4641-f9b2-8b06-7127-bb1ba1fe45d4 ro i8042.reset
