N810 (maybe N8x0 too) turns off automagically
 

I know it can reboot when it crashes, but I've noticed when it's got a good battery on it (80%) sometimes my tablet turns off overnight.
Anyone else have this happen occasionally?

Re: N810 (maybe N8x0 too) turns off automagically
 

Either something is running away and draining the battery overnight, or a dodgy process is crashing and perhaps causing a kernel panic.

Mind you whenever mine has done that, it has rebooted rather than just poweroff, but very occasionally it has gobbled battery and then switched off.

I experienced the same dead battery overnight condition. I power down my wireless access point with my PC so there's no WiFi for the N810 to connect to unless it finds a signal from another router. One morning I awoke to the sound of my N810 loosing a WiFi signal and the battery was very low. I guessed that perhaps my N810 was on the edge of another signal which came and went causing the N810 to search for a new signal repeatedly. My solution was to put my N810 off line at night and the problem never reoccurred.

i wonder if it could be related to the mce bug that causes crashes with worn batteries.

The thing is though, that I can turn it on and the battery still has about 2 bars left on it. (Advanced Power). I've noticed my Nokia Phone does this too, but it's alot more frequent (like once every 2 weeks) (this does it once a month or so)
But yeah, the battery on mine is dying, but I want a new one to replace it as this one will have bad life anyways, but you can't buy and store a battery :/... or can you?

not with rechargeable types at least. At best you can, with the lithium ion kind, charge them somewhere around 50% and stash them in a chilled (tho not freezing) and dry place. But i think they will at best last a year that way.

Re: N810 (maybe N8x0 too) turns off automagically
 

Cause someday Nokia will stop making the battery for the devices this uses and I don't think I'll be able to buy another one.

Re: N810 (maybe N8x0 too) turns off automagically
 

even if nokia stops, other will contine to i think. At least for some time.

I've read up on some others batteries, and Nokia's seem to be... 1500? mAh compared to 1200, and I read a thread on the MUGEN battery that it doesn't work very well. I need a standard battery cause I have a boxwave horizontal leather case for it that's really nice.

The mugen battery in my n800 is working fine..

As the batteries get older though, the charge meter becomes increasingly inaccurate. With my previous battery, 3 bars was 5 minutes left to empty/batterylow warning...

Re: N810 (maybe N8x0 too) turns off automagically
 

Best bang for the buck battery for the n810 and n800 are made by Cameron Sino IMO. About $9 each, including shipping, they seem to have exactly the same life as the nokia stock battery.
I have 3 of them, 2 for my n810, one for the n800.

My battery took a heavy hit today. Unplugged for about 2 hours, no open apps and bam low battery froma full charge...

Re: N810 (maybe N8x0 too) turns off automagically
 

On the contrary, almost all threads about Mugen batteries say they work fine.
I also replaced the original one with a new Mugen one, and it works fine, giving the advertised capacity. The only small problem they have is the design of the battery contacts, which are a bit loose, but it is very easily solvable with a small piece of cardboard in the bottom of the battery to keep it tight against the contacts.

Hmmm... does GPS suck serious power? I left it on w/ navit by accident, in about 20 mins my tablet was dead. Had a girls # on notes not saved... autosave is a lifesaver

Re: N810 (maybe N8x0 too) turns off automagically
 

I've a Bluetooth GPS receiver with an 1100mAh battery that lasts for many hours so my guess would be the GPS isn't your issue.

Re: N810 (maybe N8x0 too) turns off automagically
 

In our case, yes, the gps sucks serious power. Of course not enough to kill the battery in 20 min, but in about 5 hours.

Re: N810 (maybe N8x0 too) turns off automagically
 

Mine took 2 bars off and it was dead in 15 mins. Although, the 'not calibrated' part may have had an effect.

Re: N810 (maybe N8x0 too) turns off automagically
 

Maybe it's just that your battery is getting old. I think that this kind of flakiness is pretty common for an old battery.

Maybe I should try the cardboard approach. I tried putting duct tape over the bottom and it hasn't seemed to be enough to avoid glitches.

This issue has been a major irritant to me. When my N810 is on, it runs great. :) But if I reboot the system (e.g., b/c the desktop freezes), then it restarts for a couple seconds and then shuts off. Similarly, if I power the device down and then turn it on again it restarts for a couple seconds and then abruptly powers off. :mad: In order to boot again, I need to plug it into the power supply, take the battery out, replace it, push it into the connectors as hard as I can, and power on. Once it has successfully powered on, I can replace the battery cover panel. But if I have to start up away from my power cord... forget it. Sounds bizarre, but the behavior is very consistent. I can give a more exhaustively detailed account if that would be helpful. It's possible that there is some interaction with the boot menu as I am dual booting.

I am forced to reboot often since that damned second row of icons from the tray locks open and prevents access to apps in diablo5.

I have a mugen battery for my N810 and one for my N900 and they are working fine.
