N810 stuck in recharge mode - maemo.org

VulcanRidr | # 1 | 2010-06-09, 08:20 | Report

I posted about this a while back, but the problem persists and seems to have gotten worse.

Sometimes, and I haven't figured out a cause, when I plug the N810 in to wall current overnight, in the morning when I unplug it, the LED indicator remains green (and sometimes blinking) when in sleep mode...And when the display is light, advanced-powermanager has the battery with a lightning bolt in the middle. A reboot fixes it, though it has to be a hard reboot (either through pulling the battery or a reboot command from the command line...Using the power button does this wierd instant-reboot thing that bypasses the normal boot process and leaves the device in an unusable state). Another issue I have encountered is that when this happens, sometimes the battery shows about 1 bar after reboot, after charging all night.

Someone suggested restarting HAL, which restarts normally but does not change the conditions of charging:

Code:

$ sudo /etc/init.d/hal restart
Restarting Hardware abstraction layer: hald.

I also tried restarting apmonitord, which meets with somewhat less success:

Code:

$ sudo /etc/init.d/apmonitord restart
Advanced Power Monitor Daemon: apmonitord

Does anyone have any suggestions on what the cause of this problem could be (its been doing this on and off for the last couple of months, and it seems to be happening more often of late) or a fix or workaround for the problem?

Any ideas?

Thanks,

I did not encounter your problem but one possible suggestion is to replace your battery.

For one or two months, I also encountered weird battery issues like the battery bar suddenly dropping from full to near empty or my N810 spontaneously rebooting while charging.

Getting a new battery solved my problems.

Thanks Kam-Yung. I have the Mugen replacement battery that I got 6 or 8 months ago. I can try replacing it with one of the BP-4Ls that I have to see if it is the battery.

I suggest that you uninstall advanced-power, it gave me problems last time I tried it. See how the original status bar indicator behaves.
Reboot can only be done by a command. This way the file system is unmounted cleanly, apps are closed and deamons are stopped.
When you pull out the battery you introduce errors to the file system, which usually leads to...battery drain.

I second Giladmttw's comments about trying an uninstall of Advanced Power. It does cause wierd and winderful problems from time to time.

My fave is where the CPU applet shows 100% usage, everything is unresponsive, although if you can launch xterm, top does not show anythig untoward. The memory cards suddenly disappear as well.

The only solution is to remove the advanced power apps and reboot a couple of times to get rid of it.

It's done this to me a couple of times now, but as it's so useful I keep reinstalling it.

That was one thing I was thinking. Since I have my system flipped to run from the SD card, maybe there was a bad spot on it where advanced-power lived. I've uninstalled advanced-power and will let it go a few days.

If you boot from SD then you need to reboot to the flash and fsck your card. This will fix the errors introduced by pulling the battery. Do it evrytime you have a sudden poweroff.

Actually, I did that last week. 99% of the time (being a Linux sysadmin-type geek), I reboot from the terminal window. On rare occasions, I use the button, and almost never pull the battery.

This sounds like the BME bug described here: Bug 3144
