2885.1 | This A500 seems to be "kaputt". ;-) | FRAMBO::BALZER | Christian Balzer DTN:785-1029 | Fri Sep 01 1989 07:26 | 14 |

Well, if I were you Steve, I'd see to that this A500 gets replaced
ASAP, as long as it's still in waranty.
The Caps Lock flashing at power up is the normal keyboard self-test.
What your inconsistencies seem to indicate is some marginal or flakey
hardware, possibly related to the keyboard area...
Ctrl-Amiga-Amiga initiates a complete reset, that is pulls the the
RESET line of the 68000. You should use it only when stuck completly
and with no pending disk access (write) plus 5 seconds after the
last disk access.
Hope that helps,
<CB>

And while I'm at it, here's a nice tidbit from this months
introductionary posting on comp.sys.amiga:

Look on page 3 of Appendix H to the Hardware Reference manual.
Briefly, though, it says:
One blink Keyboard ROM test failed
Two blinks Keyboard RAM test failed
Three blinks Watchdog timer test failed
Four blinks A short exists between two row lines
or one of the seven special control keys.
It also says that you probably would not have been able to type anything
before this sequence would be completed, but if so, the key codes
would be sent to the computer and then a "terminate key stream" code
would be sent. There is more information in that appendix.

2885.3 | flash flash | HYSTER::DEARBORN | Trouvez Mieux | Fri Sep 01 1989 10:06 | 12 |
| My 2000 has broken down twice with a problem similar to the one
described. My machine boots fine, but the keyboard is dead. The
caps lock light flashes at a slow rate continuously.
I took the system to the dealer and they could find nothing
wrong. This has happened twice. Once it happened after a power
surge, although I don't think it is related. Maybe the ride in
the car shook thing back together. Or maybe my Amiga likes
seeing the outdoors every once in a while.

| Thanks for the info, Christian. I had my Amiga replaced, and all
seems to be fine now.
Randy, the guy in the shop implied it may be a power-supply-related
problem, but of course they hadn't investigated yet, they just gave
me a whole new set-up which works ok.
The guy also said that resetting (ctrl-amiga-amiga) did not always
completely clear memory, pointers etc. adequately if, say, restarting
on on different (just copied?) disk to the one that was originally
brought up. He said it was safer to power off, wait 30 secs. then
load with the new copy. So (ctrl-amiga-amiga) doesn't seem to be
a "complete reboot".
Cheers, Steve

2885.5 | Some RESET theory lessons... :-) | FRAMBO::BALZER | Christian Balzer DTN:785-1029 | Mon Sep 04 1989 05:59 | 21 |
| Re: .4
Well, Ctrl-Amiga-Amiga will give you a reset as migthy as they come
without power cycling the machine, which isn't the nicest thing
you can do to that silicon... ;-)
c-a-a will perform much better than the ctrl-alt-del thingie on
Messy-DOS machines, but since every processor has certain vectors
for reset time routines, modifying or munching these could give
you trouble.
The best thing is to constantly use a virus checker like Virus-X
and keep the power cycles to a minimum.
(The A500 I type this stuff in right now hasn't been powered down
for weeks...)
Glad to hear that they gave you a new "girl-friend". ;-)
Regards,
<CB>

2885.6 | loose bulkhead connector for kboard | CGOFS::R_RYAN | | Tue Sep 05 1989 13:31 | 3 |
| I have had this same problem on my A2000. The fix was the connector
on the A2000 for the keyboard was loose. Tightened it up and all
was ok thereafter.
