Plug-in and deep sleep no more...

I suspect one of the possible triggers to bad battery drain is plugging-in to AC/DC adapter.

Here was how my experiment went (conducted once so far).

1. Unplugged, rebooted with dock.

2. Ensured Auto Airplane Mode was activated.

3. Used TF now and then, monitored deep sleeping using CPU Spy.

4. All was well for about 9 hours.

5. Plugged-in to AC/DC adapter.

6. Monitored deep sleeping using CPU Spy. Deep sleeping was no longer there - maybe due to charging state.

7. Unplugged from AC/DC adapter.

8. Monitored deep sleeping using CPU Spy. To my horror, deep sleeping was no longer possible.

9. Rebooted with dock.

10. Monitored using CPU Spy and found deep sleeping was possible again.

This may mean that I must always reboot after unplugging in order to regain deep sleeping.

In the meantime, I believe there are other to trigger the battery drain problem.

just tested the above and it's the same on my machine, afer its been charging i have to close it down then restart, if i don't it won't go in to deep sleep
[Eee Pad Transformer Q&A, Help & Troubleshooting] boonkui:
Thanks for confirming it. I had confirmed it myself once again. At least, we now know there is one ritual to perform after charging.
[Eee Pad Transformer Q&A, Help & Troubleshooting] seenyisme:
just tested it again and this time it went into deep sleep without restarting?
[Eee Pad Transformer Q&A, Help & Troubleshooting] racsox:
Same here.

Enter in deep sleep, while not is charging. At the time I put to charge, no more deep sleep until reboot the tablet.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Korumera:
I've tested it, it goes to deep sleep without charger, when i plug in the charger for let's say a minute or 2 and remove it, it still goes to deep sleep. So i think that's fine with my tablet :)

Nothing wrong with battery life since last update for me, so it can't be the firmware causing the problem or it would affect everyone
[Eee Pad Transformer Q&A, Help & Troubleshooting] njdev1k:
I left my Transformer unplugged and this morning the dock battery said 0% using the dual battery widget. I folded the screen closed and opened it again and then the dual battery widget showed my dock battery was 54%. Anyone else see this?

Also, are people seeing the transformer actually run out of battery or is it the widget reporting a low percentage?

I didn't read all 9 pages of posts, so I apologize if I am repeating anything that has been said.
[Eee Pad Transformer Q&A, Help & Troubleshooting] rxnelson:
Not for sure but I think the widget can take a minute to refresh.
[Eee Pad Transformer Q&A, Help & Troubleshooting] boonkui:
This beats me. Maybe you could try a few times.
[Eee Pad Transformer Q&A, Help & Troubleshooting] demod_oz:
Mine seems to work exactly like this for anywhere from 3-24 hours. Then it will fail to go into deep sleep. Last night I charged, had 100/100 battery. Rebooted, and shut the lid (with auto airplane). Woke up 8.5hrs later, and it was 98/100. used it for a little bit, shut the lid. Looked again 30mins later, no deep sleep and went to 100/87. Reboot and I've got deep sleep again.
[Eee Pad Transformer Q&A, Help & Troubleshooting] boonkui:
I experienced this with mine before. Reboot + Auto Airplane might help only to delay the bad drain. Need a better solution.

Hmm... If ASUS could rollback the firmware update :p
[Eee Pad Transformer Q&A, Help & Troubleshooting] rxnelson:
I'm assuming since there is no charging you are not using the dock? If not I would tend to agree. I don't see any real difference between 3.2 and 3.2.1 until I dock. Then the tablet doesn't sleep until rebooted.
[Eee Pad Transformer Q&A, Help & Troubleshooting] chimphappyhour:
Yup, no idea what Asus broke but they need to fix it PDQ. We shouldn't have to be doing all of these steps to try to make the tablet behave like it used to before the last update.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Kasush:
I have been experiencing poor drain when docked as well since the update, but I also have something else happening. When my dock is 3% and my tablet drops to 14% I start getting a ? on the battery icon in the notification area and the keyboard and touchpad become non responsive. The only solution is to undock/dock. This issue repeats until I charge the system. I did NOT have this issue prior to the update.
[Eee Pad Transformer Q&A, Help & Troubleshooting] boonkui:
Wakelocks causing trouble?

This link (http://elinux.org/Android_Power_Management#Sample_.27cat_.2Fproc.2Fwakelocks.27_output) suggests using 'cat /proc/wakelocks' command to display current wakelocks in the system. It might give some idea about the processes preventing deep sleeping.

I plan to try it when my system fails to get into deep sleeping. Have anyone tried it?
[Eee Pad Transformer Q&A, Help & Troubleshooting] Preske:
I have posted this in another thread, but it can't hurt to try here. I'm seriously getting desperate.

I have a B80 Transformer with keyboard. It is a clean install (with the exception of dual battery widget), with the latest firmware. No other apps or widgets are installed/updated.

I don't put my transformer in standby, I always turn it off completely since I wanted to maximize the batterylife. Oh sweet irony, how you mock me.

I press the power button until the dialogbox pops up, and shut it down. I wait untill the screen turns back to close it.

Yet somehow, I lose up to 15% power overnight. Sometimes only the dock, sometimes both the dock as tablet. (Yes, I know the dock charges the tablet, but instead of a raising powerlevel for the tablet, both were drained)

I have tried EVERYTHING I could think off.

- With gps, without gps

- With wifi, without wifi

- with bluetooth, without bluetooth.

- Airplainmode off, airplainmode on.

- Disabled mynet, Amazon kindle, the weather app, etc.

- Factory reset.

- When not connected to the keyboard, there is NO batteryloss whatsoever.

- I both recharged the dock and tablet separately, each for 10 hours straight.

- I disabled synchroniasation.

- Sent it to RMA, TWICE, and still they didn't find any problems.

Remember, this is when the tablet is powered down, not in standby/deep sleep.

I'm at a loss. It feels like those guys in the Czech repaircenter don't take it seriously.

This has been going on for three weeks now, and I only got to use the tablet for a week...

I can't return/swap it at the store either.
[Eee Pad Transformer Q&A, Help & Troubleshooting] magicdave26:
Does it happen only when it is docked ?

Due to it being shutdown it can't be an app or setting like gps, it has to be a hardware fault

See if it happens undocked, and see if the dock and/or the tablet drain separately

You might find it to be only the dock causing the problem, I know there are some docks I think B50 and earlier that have a battery drain issue due to a certain chipset and the only repair is RMA of the dock
[Eee Pad Transformer Q&A, Help & Troubleshooting] triumph_st:
I had CPU SPy installed before the firmware update and it went most of the time in deep sleep. Now, after the update my TF does not go into deep sleep at all (0%).
[Eee Pad Transformer Q&A, Help & Troubleshooting] mlbl:
which of the figures should i be looking at ?
[Eee Pad Transformer Q&A, Help & Troubleshooting] boonkui:
Sorry, I have not read the documentation in details. I suppose processes with a non-zero wake_count numbers would be the suspects.

Anyone?
[Eee Pad Transformer Q&A, Help & Troubleshooting] boonkui:
I am not very sure of interpreting content of wakelocks file. But I found the following symptoms.

When TF is behaving well - as in getting into deep sleeping, I don't see any process with non-zero wake_count.

When TF is bad - as in not getting into deep sleeping, I see non-zero wake_count for "asusec_wake_init" process. The followings are examples (4th column is the wake_count) from two occurrences.

"asusec_wake_init"	51	0	9	0	129109858670	123939429683	2634898015	753895817134

"asusec_wake_init"	174	0	29	0	190481812487	169781969487	2621918999	1724679783062

Could "asusec_wake_init" be the offending process? Hmm...
[Eee Pad Transformer Q&A, Help & Troubleshooting] rxnelson:
Anyone make any headway with asus support yet? They keep wanting me to RMA the dock. I can't seem to convince them it occurred only after the software update. Replied back to email yesterday so i will be waiting another 3-5 days I guess.
[Eee Pad Transformer Q&A, Help & Troubleshooting] rxnelson:
I concur. I've only heard of draining while off due to faulty chipset and only option is RMA. Is it older? I have a B50 but I guess I got lucky. Mine worked properly prior to 3.2.1
[Eee Pad Transformer Q&A, Help & Troubleshooting] floatwinner:
I have found using the TF undocked after a reboot seems to sort my battery drain/ no deep sleep issues. So until there is a solution my keyboard will not be used.

Just my 2 cents...
[Eee Pad Transformer Q&A, Help & Troubleshooting] mlbl:
I noticed the battery drain issue occurs when you first run a CPU/GPU intensive app that utilises more of your CPU power for example running a game like Great Little War game, then closing it (i just left it at the menu then press the back button to exit the game). Then I go into CPU Spy, reset the timers, turned off my tablet screen and waited, then turned it back on - check CPU spy and it doesnt go into deep sleep mode at all but lowers down the CPU usage to 200-ish mhz which is where the drain problem occurs. It has to go into deep sleep mode in order to use little to no-battery which is how the behaviour was before the update.

To temporarily solve this, a reboot is required to "reset" the state. All this happened while connected to the dock but I also tried it without the dock and the same problem occured. I will be doing more investigations later today to find out what triggers this and will probably notify asus and hopefully they are already working on a patch for this.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Preske:
No, it does not happen when connected. However, both tablet and dock are affected. Sometimes the tablet loses power but most of the times, it's the dock.

Yeah, see. I have sent it twice now, and they claim it's "No problems found"

They now want me to return the unit a THIRD time, but I thinks I'm gonna call one of their supervisors and demand for rockhard guarantees that it will get fixed, or replaced.

Both of them are B80
[Eee Pad Transformer Q&A, Help & Troubleshooting] boonkui:
Maybe you could possibly get hold of another dock and perform your own experiment. And maybe get someone with tablet to test with your dock.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Preske:
I don't have any friends that have a TF too, and I'm hesitant in swapping with complete strangers
[Eee Pad Transformer Q&A, Help & Troubleshooting] demod_oz:
Don't mean to be an ass, but your problem is clearly not related to excessive battery drain after performing the 3.2.1 update. Please search for a related thread or make a new one.
[Eee Pad Transformer Q&A, Help & Troubleshooting] henkiez:
Have problem after update and now i try to downgrade but it is not working.

Problem is after 3.2.1 and tablet would not go into sleep when dock is attached.

somone now how to downgrade ?
[Eee Pad Transformer Q&A, Help & Troubleshooting] mlbl:
I did a test and so far my tests have all pointed out that the problem will NOT occur if the tablet is disconnected from the dock. The drain will/may occur when:

- Tablet is connected to the dock

- Tablet is connected to the dock first, then disconnected

- Tablet is connected to the dock first, then disconnected, then reconnected.

For all the instances where CPUSpy showed that the tablet did NOT go into deep sleep mode, the dock was connected at some point and then you disconnect it within the same boot cycle. If you disconnect the tablet, then do a full reboot, the problem will not occur. But after that full reboot (with the tablet disconnected from the dock), when you reconnect it, the drain may occur.

If it doesn't, when you disconnect it AND reconnect it back to the dock - you will see the drain. The problem is software related because before this update, there was no such drain at all despite my dock being a B50k but I believe mine is the "good batch" or the later B50k version of the dock which had no such drain issues like other B50k's had.

I would like all of you to test it out like I've just indicated above to confirm my results. So far there's never once I've not been able to replicate this issue and all this is done after rebooting, not running a single app after reboot at all except for CPUSpy. And I'm also NOT running the auto airplane mode app which I've tried for this case, it does not help at all.

Well, I suffer from the battery drain as well; having a B90 TF and a B70 dock.

So far I did the following:

1. recharged the TF with dock

2. unplugged the power, stayed in dock -> no deep-sleep, drain!

3. releases the dock -> no deep-sleep, drain!

4. reboot, no dock -> deep-sleep, no drain! :)

5. re-attached to dock -> deep-sleep, no drain! :)

after have battery problems i've been looking at a few forum and found the following which help may machine

basic settings:

wi-fi

wi-fi settings/wi-fi disconnection setting/when screen is turned off (on)

screen:

set to auto brightness

mobiledock battery saving mode (on)

applications:

applications/development/stay awake (off)

apps to install:

cpuspy (storm717) and auto airplane mode (don), restart after installing auto airplane

another tip i picked up which seems to help as well, after charging remove the cable and close down then restart

here's same examples:

before the above if i put my machine to sleep it could lose as much as 60% in about 10hrs

here's after applying the about:

on sunday i charged both the tablet and keyboard/dock to 100%

10hrs later

tablet 100% keyboard 97%

since then i've been using it lightly (mainly browsing and email, some downloading and word processing)

tonight (tuesday) when i got home from work it was:

tablet 96% keyboard 72%

the table was probably 96% because when i used it this morning before going to work i u-docked it and forgot to re-dock it
[Eee Pad Transformer Q&A, Help & Troubleshooting] dabrain42:
The restart after charging works for me - but how unconvenient is this? I would like to just charge the TF, unplug it and use it right away.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Keystone:
I have the same issue on two pairs of B60 tablet and docks. Before the 3.2.1 update the docks always were decent with minimal discharge when the tablet was docked to a keyboard with any remaining charge. After the update, the discharge rate in standby (screen off, and wi-fi bluetooth off) while on a charged/semi-charged dock, the dock will often discharge at rates nearing 20% over 2 hours.

An easy test to see if the dock is in this poor discharging state is if the system will wake-up when brushing the touchpad. It will often not do this soon after a reboot and will never do this when the dock is fully discharged.

This is certainly a software issue with either the new tablet of dock firmware. Unfortunately I know of no way to downgrade the docking firmware to a former version.

I will try to call Asus supprt today to add new tickets for this bug.
[Eee Pad Transformer Q&A, Help & Troubleshooting] jochr:
This is getting stupid!!

Full battery on the dock yesterday and full battery on the tab.

Turned it on now.. 3% left on the dock and 35% on the tab...

I rebooted after charging and unplugging yesterday. I use autoairplane mode.

I looked at the cpyspy now and it's not been at sleep at all. 200mhz almost all the time.

Did not have this problem at all before I updated the software to 3.2.1.

Asus does not seem to care at all about this problem. Suggests factory reset and RMA?!?

The last time I buy anything from Asus if they can't find a fix.

I tried it. I have B60 pad and B70 dock. During charging it would not go to deep sleep, but it might be that it is not supposed to. After charging 100/98 I pulled out the cable and put it in standby,. After 10 minutes I checked, and it went in deep sleep. This morning I checked the battery, it was 100/96... I used to have the drain issue, but now that I use auto airplane it goed in to deep sleep again. But it might be a "glitch" I will try again soon.

Nevertheless, I contacted ASUS about this problem and am waiting for their response.

It appears to be an issue with the latest kernel. Yesterday afternoon I switched from the stock 3.2.1 kernel to Blades-Clymson 21 and had no issue overnight with any abnormal drain.

I charged up my TF & dock last night, to 100% on both. Just removed from my bag, afternoon next day, and tablet thought dock was detached. The TF was still docked, but thought the dock was detached. Sounds like a problem in the tablet software to me. After I redocked the battery was at 98% for both, so I can not complain about battery discharge. Yet, entirely strange behavior.

I don't think the apirplane mode has anything to do with it. It's an intermitten problem and it could be that it would "sleep" airplane mode or not at the time you're putting it in the aiprlane mode. At least that's how it's been for me since 3.2.
