Have you tried resetting the power management settings? Apple has a til on it and for the life of myself, I can not remember how to do it offhand despite owning six 1xx machines some in various states of completeness.
Unplug the power adapter and take the battery out. Let the 140 sit for about five minutes. Simultaneously press the interrupt and reset buttons (use two paper clips or stylii) that are next to the power button for about 10-15 seconds. If you have a suspect battery, leave it out (as Chris K. noted), plug in the AC adapter and boot up.

Resetting power management on the 160 will fix that as will battery amnesia which will help to recondition the battery after repetitive uses such the powerbook may be able to run by itself on solely the battery and at the least get the machine to recognize the battery.
Unless the battery is on its way out completely. I have an old Macintosh-manufactured 140-170 battery that will boot my 170 and promptly shut down. I tricked Battery Amnesia into "draining" it and then tried re-charging it. No luck.

I need to know myself in order to replace one on my frankenstein 145 top and 145b bottom...
Wish I could remember who (at this list) sent me to this URL:
<http://www.tidbits.com/tb-issues/TidBITS-269.html>
It's the full story about the original Model M5140 power adapter that kills mobo fuses. Examine the power adapter's tip, specifically if you have that model. My power adapter's plastic insulation got chipped and fried the internal fuse. (I've ordered a replacement mobo fuse, and it's taking half of forever to come in; in the meantime, Tim Nix at the Swaplist sent me a replacement mobo, and my 170's doing fine). I'm now using a M5652 power adapter.
