only if software somehow overrides hardware, but even then the chips should be smart enough to go idle while the software fights it out between themselves...

but this is just me being a enthusiastic amateur

Update: Forgot to turn off home screen applets and put the N800 in SoftPowerOff last night....

This morning, still fully charged!?!

The only thing I changed yesterday was to disable the infamous metalayer-crawler.

Also, is the battery-status installed by default? If not, could someone post a link to the .deb ?

Thanks

First off= Thank You for the link!

Still having random overnight powerdown due to low battery.

?unrelated? I have also experienced random desktop crash / reload (to default -no Applets, revert from Personal launcher to Contacts)

I would have had a battery-status log for the last power drain... closed Xterm w/o thinking

I found out why my tablet's battery sometimes drains. I don't
know if others are similarly affected, but I'll explain in case it
might help and to see if someone can offer a solution.

I have my n810's wireless to "always ask". At home, I leave
it permanently connected without problem - the power
management of the tablet is fantastic really. HOWEVER, if
I leave my house and the wireless disconnects after signal
loss, the tablet is left in a state with wireless activated *AND*
power management set to OFF (I can check with iwconfig).
Of course, this causes a large batter drain.

This is not proper behavior. If you manually disconnect the
wireless goes to an off state called "not ready" in iwconfig.

I have to reboot to reset the wireless to proper state and then
the battery no longer drains.

Does anyone know a fix for this?

I can confirm this behaviour. It does not happen all the times, though. I just noticed that immediately after the connection is lost (and the tablet says so) things seem to be ok: iwconfig says NOT READY, but still shows the ESSID of the last access point. Can you confirm this?

The power management can be (re)enabled as root

iwconfig wlan0 power on

is this a bug or a feature
if a bug it should be listed on the bugzilla and i would vote for it- if it is a feature then it is not a good one

I did not notice this - iwconfig reports the old essid but
the powermanagement has been switched off. It does not
report the "not ready" state ...

Also, it seemed to me that using iwconfig to turn power
management back on actually did not stop the battery
drain. Only a reboot worked. But I'll have to look at that
more closely to see if it's really true.

I wonder, does anyone else see this behavior?

i have been doing some non-scientific but reproduceable experiments

the battery drain is the fastest if i leave a browser window open and then leave the n810 unattended

if i close the browser it is still very fast drain

if i manually stop browserd then *NO* drain at all



i have been tethered to my wifi at home all day with rss open and email open and occasionally clicking through to a web page but closing browserd after clicking through

since 8:45 am (that was about 7 hours ago) i have not charged the tablet... but left email (imap) on all day and rss to refresh every hour....
batterystatus says 86.8% the battery icon says Estimated battery time left, when idle 9 days and when in use 5 hours.

home applets running- internet search, gpe summary

in my non-scientific opinion it is browserd that is causing the drain

I have similar experiences. When moving away from WLAN something not visible in load-applet is using a lot processor cycles resulting in battery drain and making network connection selection unusable. Only way I have found to solve the situation is rebooting apart from manually disconnecting from the network. I have yet to try iwconfig method mentioned above.

This does not happen every time when changing locations and started happening just a few weeks ago. I have had Diablo on my N810 since its release.
