Win XP Pro.Â* Lenovo T500
Need to figure out why my laptop keyboard sometimes goes dead.
I cannot associate it with anything.
No other problems.
I see no Fn button to do this.
The USB mouse keeps working.
The mouse pad is turned off.
What apps might cause this ?
What actions I might have taken would cause this ?
Is there some Win+Key that does this ?
Suggestions please.
Many people want to be able to disable the touchpad because it can be
activated accidentally during typing.
I believe Fn + F8 disables/enables the touchpad.
If you are using a USB mouse, it would be better to keep the touchpad
disabled altogether.Â* I don't know if you can disable the touchpad in
the BIOS of the T500.
There is not a function to disable the keyboard, except that someone has
written software to disable the keyboard and touchpad and also turn off
the sleep mode - because it would be difficult to awaken a sleeping
computer with the kb & touchpad/mouse disabled.

Thread: Disable/enable keyboard and mouse input OS-wide with a key
combination
I'm not aware of any keystroke or function keys for disabling the
keyboard so I don't think it's something you are doing.
You might want to check out the power settings and verify anything
related to keyboard is told to not power down try to save power in any
fashion.
Unless you are using the bootleg patch you would not have any Windows
Update trashing your system. But still, it might be worth burning a
restore point back to a date before this started happening. Possibly
something sneaked in and is confusing your keyboard's driver.
The keyboards do plug into a connector on the motherboard and it is
possible for it to come partially loose. A quick YouTube search should
get you a how-to on removing/replacing the keyboard for your model.
Take care as some of those connectors can be quite fragile.
When you get the problem, try plugging in a USB keyboard and see if it
too fails to work. That would indicate something in the Operating
System or motherboard. If it works just fine while the internal
keyboard is still dead then if it were mine I'd be looking into the
keyboard connector.
