KX1 Q: Processor won't reset? Rig confused. Why?

[ne1rd]

I have a KX1 that has worked flawlessly until now.
(Just got my 1000 miles/watt award. Cool!)
I run it off batteries and listen to it at night before bed. I fell
asleep and
forgot to turn it off. A day later, I discovered it just sitting there
with
very nearly dead batteries and the left-most LED blinking.

It now has new batteries but it has become nonfunctional.

Symptoms:
1. Processor will not reset as per manual.
    I hold down the BAND+MENU buttons at power up but the LEDs stay dark.
    I never get the "E9" or "E10".
2. It appears as though the "Dah" paddle is depressed, though no
    paddles or key are connected. Putting paddles in and pressing
    "Dit" will do the iambic thing.
3. BAT LO will occasionally pop-up after power up.

I am confused because:
1. Nothing physically happened to the box except it sat there until the
    battery ran down. Why would it now act like the "Dah" paddle was
pushed?
2. Why can I not reset the processor?
3. Batteries are new. What's with the BAT LO thing?

Things I've tried:
1. Disconnected the ATU.
2. Disconnected all power for a while, hoping to get the processor to
behave.
3. Applying external power (not just AA cells in the belly of the
beast).
4. Disassembling the unit completely (except for 30m board) to see if
there
    was a problem visually.
5. Tried applying power with the unit out of the aluminum case. No
change.
6. Resetting the processor repeatedly, without luck.
7. Version number check (any switch on power up) DOES work. Version=101

It is time for me to put it on the bench and start checking voltages.
But, I fear that the processor has somehow lost its mind. Has anybody
seen anything like this? Is there anything I'm missing?

Sorry for the long note. I will, of course, let the list know what
was done to resolve this once I get the little gem back on its feet.
Thanks. 73!

My KX1 is on the mend. The capacitor C32 had somehow become
a 2K resistor while I wasn't looking. I clipped the lead and
got the E10 message on the LED. I don't have any 0.01 caps
quite that small but I've got a couple that should fit if I
bend them over. They're just bypass caps so value, type, and
size shouldn't make that much of a difference. (I whacked
C33, too, while I was at it, just to be sure.)

Thanks to anybody who took a look. I hope I've posted this
soon enough so I didn't waste too many people's time.

73!
