Hot pluggable?
-
I know you're not technically supposed to but.... Hot plugging/unplugging a standard 15 pin vga monitor cable, has anybody here ever fried anything doing this? Just wondering as I've been doing it for years (hot plugging monitor cables that is, not blowing things up :laugh:) and never had an issue I run my laptop on a flat panel when at home, so I plug the cable in, THEN switch to the external display under display properties and the reverse when switching back ie switch back to laptop display, THEN unplug the cable. Theory being there shouldn't be any voltage running through the socket when running on internal display (Although I guess there may be some residual voltage) Anyone?

May not really be related, but I can only hot-plug into/outof connectors that were connected when the computer booted. Any other connectors are ignored completely, plugging a monitor into them results only in frustration. So far the old CRT screens that I've been doing that with haven't died..

I've never heard of a restriction on hotplugging VGA cables and've done it for years without trouble. AFAIK all the (normal) external interfaces on a PC are and always have been intended to be hot pluggable (at the hardware level at least).

Same here. Been hotplugging everything for since I had a computer. The only thing I don't hotplug/unplug would be the power cable. Hmm...actually I might have done that once or twice..:~

Never heard of a problem doing that to VGA, or most other connections. The only issue I've ever had was with PS/2 keyboards not being recgonized on a few systems.

It's not advisable but highly unlikely to cause any problems. The connectors are polarised so you'd have to try really hard to short anything or connect the wrong pins. The only possible dangers I can see are from rapid switching as the contacts 'bounce' which can in theory blow components and uCs, plus generate alot of heat very briefly. I've done it for years too and never had a problem - but there's always a first time I suppose!

I once disconnect and reconnect a hard drive while power was on and caused fire that totally burnt the hard drive. I still do not believe what happened.

If that's an internal hard drive, I am not surprised; they often need three voltages, and their power connector does not provide power sequencing (applying the voltages in an acceptable order). One should not plug/unplug internal connectors while power is on. On the other hand, external connectors should be pretty much hot-pluggable; if they were not, the repair shops would be flooded all the time, and users would complain to the hardware vendors. Of course the bus-oriented ones must be hot-pluggable, such as USB, FireWire (IEEE-1394), and GPIB (IEEE-488). :)

No horror stories so far then apart from the guy who set fire to a hard drive! Think I'll carry on then :)
