Wallstreet battery problems

Message #1 - Posted 2005/01/15 - Dan

Trying to figure out (before spending money!) whether the the problem is with the PRAM battery, power battery, PMU, which two of those three, or something else....?

Let's see...
--the PRAM battery is apparently dead -- the date/time (usually) resets when the machine is shut down.

-- the power battery seems to have a good charge, but the pb often doesn't recognize that it's there. Says the bay is empty.

-- Sometimes if the battery is removed and reinserted, it will appear on the screen, only to disappear a minute or two later-- If I try running on battery power, it gives me a "no reserve power" warning and goes to sleep (doesn't just shut down dead) which makes me think this is not due to a mechanically intermittent battery connection.

TIA
Dan

Could be both! Can you borrow a battery from someone you know with a Wallstreet? Or take it in to a Mac shop and have them look at it.

Sounds dead. You can also try putting the machine to sleep and removing the regular battery (with the machine unplugged, of course). If the PRAM battery is good, the Wallstreet should be able to maintain the sleep state for sometime (30 seconds?) so you can swap batteries without shutting down.

The Wallstreet has a problem with the battery not maintaining contact. Check that all the screws holding the front edge of the machine together are tight:

I also put a couple of layers of electrical tape on the front left corner of the battery to make the battery snug. Don't put too many layers, the battery will get stuck.
