Keyboard Goes Dead
Win XP Pro. 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. 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. https://forums.embarcadero.com/threa...71474&tstart=0 Thread: Disable/enable keyboard and mouse input OS-wide with a key combination -- Mike Easter |

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. |

That's pretty model (or at least make) dependent. On this Toshiba Portégé, there's a little long button between touchpad and spacebar that toggles it, as well as Fn+F9 (no, I don't know why they've provided two methods either!); Fn+F8 toggles the wireless. But that's the touchpad, not the keyboard. If you are using a USB mouse, it would be better to keep the touchpad disabled altogether.* I don't know if you can disable the That's very _user_-dependent (-:. If you're using an external mouse because you can't get on with keypads, yes, disable it; I find there are things both mice and keypads are better at (different for each, of course), plus my fingers are _used_ to using a keypad when I'm using a laptop, so I'd probably leave it enabled. But again, that's probably a red herring/irrelevant to the problem! [] 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. Me neither. [] 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. Shouldn't hurt. Although as the OP has said he can't associate it happening with anything, it'll be difficult to prove it's been fixed (though that will apply to our other suggestions below too). The keyboards do plug into a connector on the motherboard and it is [Or I think sometimes into a connector on a little board/card that it itself connected to the mobo.] 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. May well involve removing some of the screws from underneath. (Including ones under other things - such as inside the battery, HD, or RAM flap.) As GBM says, there may well be a YouTube clip showing such details. The connector is often just the stiffened end of the ribbon from the keyboard, which goes into a connector and it held down by a (fragile!) plastic clip. 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. Good thinking. (If you find you _do_ need to replace the keyboard, and your model comes in white, consider getting a white keyboard, even if your laptop isn't: they're _much_ easier to see in low light!) -- J. P.
