Not a suggestion of what's wrong, but a question: can you tell if Windows thinks it's a PS/2 or a USB keyboard? This might help others wiser than I to make suggestions about what's happening (or not). I'm _guessing_ that (a) it thinks it's PS/2, (b) there is a fragment of dirt - or otherwise loose connection - somewhere, that very occasionally isn't making contact at the point during boot that it looks to see if it's there. (PS/2, unlike USB, are only detected at that point; if you plug them in afterwards, Windows doesn't notice you've done so.) The most likely place, I suppose, for the grit is in the ribbon connector under the keyboard; I don't know the T500 as such, but most laptops/netbooks have a keyboard which is a separate module, connected to the motherboard by a ribbon connector. Not usually a plug-and-socket like EIDE or even SATA - it tends to be a "connector" formed by the end of the ribbon cable itself made stiffer by the addition of side contacts, which goes into a slot, and is held down by a fragile clamp. But it _could_ be somewhere else - my second guess would be where the connector (the slot part _is_ a board-mounting connector) is soldered to the motherboard. (Or possibly where the other end of the ribbon is connected to whatever's inside the keyboard module; I've never been in there; a replacement keyboard would probably be easier.) Or it _could_ be a software fault, though I can't think what. In the meantime - Start | Run | osk to get the on-screen keyboard, which you can use with the mouse, and it should remain in the Run memory so you can bring it up next time it happens, and use it with the mouse (or set it to come up, minimised, with Windows, or from a desktop shortcut) - that'll allow you (somewhat tediously) to do simple things when it happens without needing to reboot, if you'd only turned on the machine to do something trivial. (Don't wait for it to happen - do it now; you need a keyboard to type the O, S, and K!) Or get a USB (external) keyboard. (If, next time it happens, you plug in a USB keyboard, and it _doesn't_ work, that may be useful information too.) -- J. P. Gilliver.
