The other day I stumbled across a trick that lets me boot my SL-6000 even with the battery completely removed. Of course, AC power is required. Normally, if you take out the battery and hit the power button, the Power LED will just blink and nothing else happens.
But there's another alternate boot procedure. It's the "D+B+reset" emergency boot that boots into the special rescue/update partition. And, I was astonished to find that this boot method works even with no battery.
Anyway, once the emergency boot is finished, you get a login: prompt. Just type "root", and then, at the command line, type "reboot" and the Zaurus will reboot into the primary ROM. All without any battery.
Anyway, I'm curious to know if this works on other models too.

Doc - I finally was able to duplicate this (partially) on my C860s. BUT there is a twisty trick to making it work and a nasty joke at the end.
The first way that I tried failed.
Pull battery & wait briefly.
Plug in AC. No lights (as expected).
Flip baattery switch to ON & charging light starts to blink.
D+B & press the back button --> NADA.
The steps that you must go through to be successful in the first stage are:
Pull battery & wait briefly. Flip battery switch to ON.
Press & hold D+B (or D+M etc) THEN plug in the AC.
NOW the C860 boots to the D+B command line & reboots to Qtopia.
HOWEVER! As soon as the GUI loads, up pops the "Battery Low. Charge the battery" warning window and it WILL NOT GO AWAY or let you do anything else.
So I guess we old C860 users are still SOL if we don't have a charged battery when the lights go out. (G)
