OT: key 0115 on my laptops keyboard interferes with USB link
Sorry if this is Offtopic but I have done some research on this problem (if my interpretation of the symptoms is correct) but couldn´t find any hint in the internet, therefore no idea how to proceed. Since recent the keyboard of my laptop shows some weird behaviour. Right after switching on the boot process (loading the bios) will only continue if I press a key on the keyboard. Any will do. After that Suse 10.1 boots fine while with XP they keyboard is just dead. I suppose the keys are dirty and need some cleaning The interesting thing is now that in the log of some program connecting via USB to an external handheld CAS a line shows up which isn´t in the program code (the developer tells me so). It says: ticalcs-INFO: sending key 0115: It could very well the one keyboard key which causes this whole bunch of problems. Any ideas or infos on this? Thanks! Guido

It does indeed *sound* like one of your keys is either stuck or got a drop of cola or something in it and has a short circuit. Ascii 0115 (octal) is '\r', which makes me suspect your RETURN key (but that would be curious because under Linux the RETURN key emits '\n' (octal 0112)). Try removing it, cleaning it out with a damp cotton swap, and let it dry for a while before turning it back on. If you smoke a lot of pot around your keyboard, sometimes a drop of "crud" will land down in between keys, which might be sticky due to the resin. (No joke - it's happened to me.) In my experience, most machines will beep constantly if a key is stuck down at bootup. i've also had it happen, however, that a key isn't constantly stuck, but sticks every so often. Also try using your BIOS setup, just to see if you can move through the menus and such normally. If you can't, the keyboard may very well be the problem. It's a laptop, so if you care to "get crazy" (as the painter Bob Ross would certainly have put it), you can try removing the keyboard and plugging in a USB one just to test it out. However, just plugging in a USB keyboard won't (normally) also deactivate the builtin keyboard, so you'd need to remove the builtin keyboard to be sure. Most laptop keyboards can be removed by using a small flathead screwdriver, or similar, to slide a few little latches out of the way along the edges of the keyboard. Somewhere under the keyboard will be a cable that attaches to the mainboard. That is normally unlatched with a small slider on either side of the connector directly on the mainboard. It can sometimes be tricky to get the keyboard connected again, though, because the latches are so tiny. -- ----- stephan@s11n.net http://s11n.net "...pleasure is a grace and is not obedient to the commands of the will." -- Alan W.

Alright. I seem to be on the right track. That´s what I needed. Thanks.

Well I don´t smoke at all. No pot, cup or bottle. I prefer the latter for beer. The first for soup, which indeed could have dropped onto the keyboard at some time. Beer too, of course. And, come to think of it, lot of other things as well.

Well that´s another problem. Since the keyboard does not work properly during startup it does not allow Alt+F2 to start the bios setup. I put all my hope into the big cleaning session. Thanks for the advice! Guido
