This was happening on my girlfriends n900 yesterday.

She charged it to full and took it off charge at about 11am, it started beeping low battery at 4pm.

I had a look at top and eapd was at 92%.

I killed it off and the process table seemed to go back to normal.
I asked her if it was happening alot and she said it had happened every day for the last few days. Her uptime was over 5 days.

What I would like to know is what initalizes this process, and why it brings the phone to it's knees. Is it a memory leak or something she has possibly done? We're off to Amsterdam tomorrow so I need to get this sorted today.

BTW she's on PR1.3, kernel power 46 running at 1000mhz.
Thanks
