What happens when you remove the battery while the n900 is still running?
 
I have just recently ran into this issue from an at&t rep. who has been backed up by multiple managers and supervisors. The claim is that removing the battery on a N900 is just a soft reset and cannot, in any event, damage the device. However they all admit they know nothing about this particular device.

Correct me if I'm wrong but doesn't ohm's law apply here?

And if so couldn't the increase in power draw damage CPU pins, arc the motherboard socket, fry the regulators on the motherboard, melt traces on the motherboard or in the CPU, and do any number of other horrible things to the hardware?


I have been experiencing issues since the incident as listed here:

Can someone provide links or other info? Google doesn't seem to be very friendly right now.

I have pulled the battery from my (half)running Samsung OmniaHD a bazillion times when it got stuck yet again. Never hurt the hardware. And that phone uses the same TI OMAP package as N900.

It cant harm the hardware, but surely can screw the software.

Thanks. I'm glad I can rule out hardware damages.

What software damage may happen and through what way?

All sorts of filesystem corruption basically.

I often switch batteries, and a number of times I didn't notice I was pulling the battery on a still-running N900. It didn't do any apparent harm.

However, if it had I would simply reboot and run Backupmenu and be fixed again in minutes.

If it had done such apparent harm as corrupted file system, you would not have been able to simply reboot and run any application.

Backupmenu works differently. You don't boot to maemo and then use app called Backupmenu.You use it before maemo even starts to boot.
