Hi Matt, It wouldn't surprise me if the 50ct DIDN'T have a key combo, there were a number of laptops by both Compaq and Toshiba about that era and perhaps a little earlier that either didn't have the option or had problems (the Compaq Contura comes to mind - it DID have the button but it only worked properly if the planets were in the right alignment and if Jupiter was rising in Orion and ... you get the idea). Generally hot plugging monitors (or most other things for that matter) isn't a big problem from the point of view of hardware (of course, if your software doesn't know about it then you're often sunk) and it'll certainly solve the "Can't see the screen to boot" problem (plus it'll also save your audience from having to go through the boot process with you). Once you're in Windows without the external monitor, you can hot plug the monitor (it won't be active yet so it should be even safer than normal hot plugging) then use the display switcher (start>programs>toshiba utilities I believe) to get your external monitor going (you can assign this to a hotkey if you like or if you don't like the idea of hot plugging). If you're worried about the sparks that you sometimes see when you hot plug battery powered devices together (as the ground rails equalize) you can hold one of the port shells on the lappy and touch a ground point on the monitor with a finger before you bring them together. I've never damaged a video card or a monitor by hot plugging, certainly even the cheaper KVM switches effectively hot plug monitors in the way they switch from one set to another (and where I used to work, we'd switch monitors a few times every hour and these monitors and video cards have been doing this for years without ill effects). OK correction, the only time I've damaged a monitor by hot plugging is when I slipped and bent the pins on the back (but thats a different story ... hehe). I dunno about your walkman issue, I've not gotten around to getting an adapter that'll let me plug anything into the 1.5mm phono jack in the back of my lappy yet ... one thing you might wanna try though (in the unlikely event that you haven't already tried) is to turn the volume on the lappy down and the volume on the speakers themselves up. I find that with Toshiba Satellite and Tecra laptops (the few that I've used anyway) you tend to overdrive powered speakers if your volume level on the laptop is over about 1/4 level. Regardless of what the manual says, the 'headphone' port on most of the laptops I've seen are powerful enough to drive 8 ohm unamplified speakers to a comfortable level without any ill effects (if you wanna double check you could get your ohmmeter out and check your walkman speakers but they're unlikely to be anything less than 8 ohms in which case it should be fine). You probably found a difference going from NiMH to alkaline because the amplifier in the speakers would probably have been biased for 1.4-1.5 volts per cell (where NiMH only gives 1.1-1.25 volts per cell), this coupled with possibly overdriving the input by turning the volume on the lappy way up will almost always cause distortion. Bear in mind that those things weren't designed to give a big sound ;-) *sigh* the next question is why the heck I felt compelled to write all this when I really didn't answer either of your questions ... ah well ... I might as well ask a question of my own to make this post worthwhile. Does anyone know if there is any way to emulate the numeric keypad and other extended keys on the Libretto keyboard (or if there is any program that'll allow me to map key combos to emulate the numeric keypad)? Alternatively does anyone know how to do ASCII characters (eg. Alt-0186 to type the 'º' character) WITHOUT having to fight through charmap? - Raymond At 09:23 PM 27/09/2001 -0700, you wrote: >Date: Fri, 28 Sep 2001 04:15:30 +0000 >From: "Matthew Hanson" <[EMAIL PROTECTED]> >Subject: Key commands and impedance > >Two questions for anyone who might help: > >1.
