Pull the plug = shutdown

[link1305]

This just started in the past day or so with my Latitude CPX laptop (650mhz). Whenever you unplug the power cable, the laptop shuts down immediately, even though the battery shows 100% charge. Even though the BIOS the battery shows full charge. Once it shuts down (with the power cable pulled) it won't boot up again until you plug the power cable in.

Any ideas?? I'd appreciate it, a laptop isn't worth much if it can't be portable.

here's a few ideas :)

Have you previously drained your battery to zero??? Some batteries have a protection circuit that prevent your battery from draining to absolute zero thus preventing damage. after the protection circuit is triggered, you may need to reset your battery. (look and see if you have a tiny (pinhole) reset button on backside of battery). also if you haven't done so... remove your battery and re-insert it. also it may be possible that your battery is damaged (or even your motherboard) and is reporting an incorrect value.

Ran into a similar situation with a gateway from work. try removing the battery and then just putting it back in, also try pushing on the battery as you boot up. If either of these work then the plastic that holds the battery in is just too worn and you'll have to replace the battery. Also good to know is that "almost all" laptop batteries have a built in fuse to keep the battary from blowing up if it's overcharged or shorted out.

if you happen to have a volt meter/know anything about electronics try seening if there is actually any charge left in it... like said above you may have drained it to zero and now the computer reads 0% as full charge...

My new Gateway has a recalibration process that is used when exactly what you describe occurs.
