Re: The power on/off enigma..
 

My only advise for the buy.com return is to request a refund and order a new replacement. Otherwise you will be without your tablet for about a month.

It takes a week to send it, 10 business days to turn around the replacement/refund, then the time it takes to receive the new unit. Both my brother and I had really bad experiences with our buy.com returns. Crappy customer service for returns! They seem to be unable to process simple logic. But with that being said I still shop there, Iam just more weary.

Re: The power on/off enigma..
 

I tried to do that but for some stupid reason I could not create my RMA as a refund. I called and they gave me some lame excuse that since I ordered it online (hello? buy.com is online!!!) they could only give me an exhange. Yep, I'm stuck waiting a long time! I just need to have faith now.... :(

Re: The power on/off enigma..
 

Yeah, I went ahead and did the same. Got it out on Thursday or Friday. We'll see how long it takes to get one back.

Re: The power on/off enigma..NEW information
 

For the 1st time my N770 would not turn on..the only thing I did different was to use the device mode switch off screen vs. just holding down the power button as I have always done...after taking out the battery and plugging in the usb power supply cable it would turn on and is working as before....one would think it is a software conflict not a hardware issue....:D

N770 2007HE, skype, etc.

Can not yet get maemo mapper to work with my i.trek M3...yet did get TomTom to work on my N82 with the i.trek M3 not the internal A-gps...

Re: The power on/off enigma..
 

One broken here too - N800. Updated from 2007 to 2008 no difference. Only thing witch seems to work, is waiting around 30 minutes between on/off.

Re: The power on/off enigma..
 

I found a page on the nokia forum (which pointed to this thread), suggesting that one take out the battery and wait a few minutes (until the internal battery runs down). Then put the battery back in and plug in the power adaptor. Wait until the charger light comes on, then the Nokia will boot.

This has worked for me twice now, I hope it is not just luck. :-)

BTW, someone asked why ever turn it off. I can think of several reasons:

- flying ;-)
- when it loses track of it's SD cards, rebooting seems to cause it to see them again.
- it seems to work better changing the SD cards if I turn it off while doing it.
- every so often it seems to lose any ability to play sound, rebooting fixes it

Re: The power on/off enigma..
 

My new N810 from Buy.com also suffered from the power on/off enigma, however when I first got it, the unit was great for the first few days. Now I am a newbie at this tablet, but I love it and the issue only developed when I was loading on tons of applications and figuring things out for myself, and although I have read the forums weeks before receiving my unit I am still learning.

Once this issue popped up I at least had a reference for it, and how I fixed mine was I flashed to the newest version (which was already on the device) and now it works 100%. That tells me it was software based and not hardware or firmware causing the issue. I have seen some people post different issues, but this is my experience. This is not me saying this is the cause, simply what I have been a witness too.

I hope this might help someone out there who has this issue, the apps I was loading on that might have caused this were wireless tools and or aircracks to try my unit out at getting some access point access around where I work. Nothing bad just want to see how long it would take and if it would be worth it doing so when I travel around (I am sure this would depend on the encryption, WPA vs WEP and so forth). I was going to flash it anyway after I had some time playing with it, at least I know I can always go back and it is nothing permanent on my unit. Hope this helps someone out there :).

Re: The power on/off enigma..
 

Well, I flashed and re-flashed all three available versions of the available firmware (which is difficult as the device won't flash while the problem is in effect) and still experienced the problem.

After getting mixed signals from Nokia 'care', I contacted Misco, where I got it from, yesterday and they sent someone to pick it up today. They also sent someone with a replacement one ... which arrived today. The extra bit they charged more than Play was well worth a) them having it in stock when I ordered and b) this level of swapout policy :)

I've been playing with my new unit (which says 2011 on the PCB) and not had a problem yet! My case definately looks like a hw related problem as I could reliably get the old one to fail to boot within half an hour of trying.

Let's hope that this isn't my second 'spoke too soon' moment in this thread. :)

Re: The power on/off enigma..
 

I have cured my problem by turning off extended virtual memory. The problem seemed to show itself as a mistimimg in the boot sequence (ie doesn't). Of course can't guarantee this is the whole problem.

Tools > Control Panel > Memory > Virtual then don't check (or uncheck) the extended memory box. Then OK.

Re: The power on/off enigma..
 

Well, after having my replacement for two days, I still haven't had a problem.

When I was suffering from it, the issue was very transient and unpredictable. I am now of the opinion that none of the 'solutions' to this problem actually work, but that the system coincidentally worked for a couple of times after doing them (remember a correlation of events doesn't show a cause). The solution is to get the device replaced with a working one.

Re: The power on/off enigma..
 

My thoughts exactly (and that's exactly what I did). My replacement unit is still working perfectly after the better part of a month now. Turns on quickly and easily each and every time I push the power button.

Re: The power on/off enigma..
 

What would people recommend to a recent buyer who has the issue? Send it back and hope the new one works right? I wish Nokia would update us on this issue. And the GPS as well, I'll be pissed if they release an N815 with better GPS.

Re: The power on/off enigma..
 

How's this related to switching the device off? You are just rebooting it without switching it off. You might actually switch it off using "shutdown -h now" but i doubt that this is technically any different from switching it off from the menu that pops up when you hit the power button for a short time. All these approaches finally trigger the same mechanisms to shut the device down and i really doubt that this makes a difference with respect to the power on off enigma.

My n810 had this problems in two of the three times a have switched it off the last three days. I have never had this before with my n800, so there's definitely a difference. Also the tips here (plugging the power supply in for at least 35 seconds, ...) didn't help. What did help was that i removed the battery for a few seconds. After that i could switch the device on.

Re: The power on/off enigma..
 

TO EVERYONE WITH THIS PROBLEM:


Can you tell me something: is this problem a standard for ALL devices, or is this power issue a rarity?

I've done my homework for days now, and so far I have yet to find one reason as to why I should not order a N800, and I'm ordering two. One for me and one for my GF.

This power issue is extremely discouraging.

Furthermore, I have yet to read anything of a success story by sending one in to Nokia.


Has anyone with the problem sent their N800 in to Nokia, and recieved a fully functional device?


Please, let me know, anyone. This power issue, by far, makes it extremely frustrating to want to order them, as everything else I have found seems to be non-existant once I find that that particular problem doesn't really exist, through a little extra digging. But this power issue doesn't seem to have an end. :(

Please, let me be wrong.

Re: The power on/off enigma..
 

I am suggesting a way to get around this SERIOUS problem. You dont understand. NOT my problem.

akd: I am also curious to see how common is this problem. You think you can set up a poll to ask for people to cast a vote that they NEVER have this power-On problem, i.e., their device come on ANYTIME they hit the power button or however they hit it, ever since they own the device. If the vote is more than a couple of hundreds, then I will say the power on enigma is really a small batch of unlucky tablet owners.

Mine is about 50-50, so it is VERY frequent. And it happens more during the end of the day. Now, I bypass the problem by NOT turning it off, just reboot if the tablet mess up or if I have to switch to different OS. I do not have to 'fear' this problem for over 36 hrs and for the first time, I am leaving the charger in the house. Yup.

Re: The power on/off enigma..
 

Yes, me :)

Well, not returned directly to Nokia but where I bought it from. I'm pretty sure at least one other in this thread has sent their tablet back and received a working one.

Re: The power on/off enigma..
 

My first 810 had the power on problem and I took it to be replaced and got a new one. Never had the problem since.

Re: The power on/off enigma..
 

Bun: Poll is open. I've decided to open the power on problems by model. If you think it can be improved, fell free to let me know. ;)

Re: The power on/off enigma..
 

Hello again, I'm back with a updated summary of my n810 experience to date:

I purchased my brand new unit on December 6, 2007, and immediately had trouble turning it on after the initial battery charge.

Unable to find a complete software / finesse solution to the issue, but loving the n810 so much that I didn't want to give it up even for a day, I eventually and reluctantly decided to send it in to Nokia for warranty repair. Their turnaround time was spectactular by anyone's standards: they received the unit on January 10th, performed their repair tasks, and then mailed it back to me on January 11th.

Now that I have the "repaired" unit back in my possession, I will tell you all something that will make your hearts sink. I STILL CAN'T TURN MY TABLET BACK ON WHENEVER I WANT. They sent back the same unit, with notes that were not as detailed as I had expected. "Fault Information: NO PWR UP/DOWN / INTERMITTEN" and "Repair/Parts Used: Full Software Upgrade & Phone Reset"

The fast turnaround time was great, but I would rather they had kept it for an extra day or two to actually test it and make sure it worked properly before sending it back.

Just a couple of days ago someone posted a brilliant idea:

xterm
sudo gainroot
shutdown -r now

Restarting my tablet is now a no-risk gamble. Thank you, bunanson.

Unfortunately, as expected (but worth a try) . . .

shutdown -h now

did not change anything, my unit is now off and cannot be turned on. I have plugged it into the AC adapter and expect it to display the battery indicator within an hour or so, and then I'll be able to power up again.............................. ok, it just came back on. That time it took about nine minutes. Not so bad for a completely unpredictable issue, eh?

Since I've had this thing back from "repair" it has recovered in less than an hour each of the four times I have tested it. All I have done to get it working again is:

Sigh
Plug it into the power adapter
Walk away

When I come back to check on it, the battery charge indicator is displayed on the screen . . . indicating that the unit is alive again and ready to be powered up.

I ordered another n810 (directly from Nokia this time) yesterday, and once I have it I will send this faulty unit back to the repair center again.

Re: The power on/off enigma..
 

It defintely sounds more like a hardware problem rather than software.

Re: The power on/off enigma..
 

I completely agree.

Re: The power on/off enigma..
 

I bought an HP media center laptop, not the cheapest one by any standard, sent it for repair after 'chatting' with the HP tech for hrs, it came back exactly like what you have, a note not quite clear what had been done, and the problem was solved upon initial reboot and that is all. The problem re-surfaced after a 2nd reboot and the problem persisted till today, which is almost 9 month into the ownership. Thank you for sharing your experience with us. Good luck for your next N810.


bun

Re: The power on/off enigma..
 

I had a change of heart after finding out about shutdown -r now. It gets me past the power-on problem, which was the soft solution I've been seeking for the last month or so. I canceled the order I placed for a second n810, and plan to keep on playing with this one. I never shut this baby off anyway, so the power on issue only troubles me when I need to restart and it won't come back on. The ability to restart on demand is at least an order of magnitude better than the ability to turn off and then back on again. ;) It is funny how tolerant we can be of fundamental tech problems as long as the overall experience with a device is awesome.

I installed Canola 2 today . . . BEAUTIFUL APP on a BEAUTIFUL TAB. :):)

Two thumbs down to HP for sending your laptop back to you in the same condition you sent it to them. ;)

Re: The power on/off enigma..
 

Unfortunately that sounds typical of Nokia's repair "service". I had to send in a Communicator in FOUR times in succession until they relented to fix an obvious hardware fault. Each time the fault ticket notes made it clear that would not solve the issue, but every time it came back with some "fix" that was irrelevant to the reported symtoms.
I think the problem is that Nokia's fault logging system only caters for preselected conditions from drop down lists, so the whoever is creating the ticket has to select the nearest even it's nothing to do with the actual symptoms. To mae this worse, it's obvious the monkeys in the lab never read the notes ,or haven't the intelligence or motivation to do so. If they had, they would had done a first time fix on my phone's hinge, not reflashed the phone or replaced the keyboard. Instead it seems they just slap in whatever they feel like just to close the job and keep the "jobs per day" bean counters happy.
From my experience with 770 WSOD fault reporting, Nokia's logging system doesn't even understand what an Internet Tablet is (otherwise why do they insist on an IMEI), so the chances of it getting proper attention without multiple visits and escalations until you bust a blood vessel, are even less likely.

Re: The power on/off enigma..
 

Done.

I execute a small utility file from osso-statusbar-cpu, which allows one to put in some simple commands.


0) osso-xterm and becomeroot installed.

1) install osso-statusbar-cpu from debfarm, http://debfarm.free.fr, chinook, user or go www.gronmayer.com/it/ and search for it. You need to reboot to make it work

2) in the osso-statusbar-cpu icon>Settings...>Commands> New> Command: type this "/home/user/bb3.sh" (no quotation) and in the description, give it a name, I called it Bunreboot.

3) dl the bb3.txt and rename it bb3.sh and copy it to /home/user
4) chmod +x /home/user/bb3.sh
I do not know how to upload a .sh file :(. Hey you, stop laughing...
I hope changing the .sh to .txt and back to .sh will not disturb anything, or someone just have to teach me how to upload a .sh file.
Or, you can open the bb3.txt file and type in the code yourself.

This is a reboot, so save your work before reboot, unsaved work will be lost. From NOWON, just click Bunreboot ANYTIME you want to reboot.
bb3.sh should work for N810/N800/770 as long as you have osso-statusbar-cpu installed.

Enjoy,



bun



Post back if question. It works for me so far. Just for fun or revenge to the tablet, I have rebooted 10 times, work very well, only if some knows how to compile it into a .deb and put it on the desktop, that would be perfect.

Re: The power on/off enigma..
 

For anyone with this problem, Eero Tamminen from Nokia has just posted an update in the bug report confirming it is a software issue and will be fixed in future (hopefully in a few weeks).

Re: The power on/off enigma..
 

That's funny -- I never saw the freezing suggestion. I bet not many people tried keeping their tablet in the refrigerator...

Re: The power on/off enigma..
 

I'll be glad if Nokia can find a solution for this. But I can't be very optimistic. If the problem is software-related..why not all the units are affected? Have they different software? Why Nokia have exchanged faulty units and delivered exchange units that work fine? Why always they returned "serviced" units the problem persist? (All based on users comments).
In my particular case, I've the problem ALWAYS if I wait a time (let's say 30 min. or more) after turn the unit off and then try to turn it on. If I turn it off and immediately turn it on, the unit works fine. Could that be a software-related problem? Only the time could tell :o
Finally, I suggest all users reporting non affected units, to do the power on/off test turning they units off and wait an hour or more to turn the tablet on again (just to be sure)

Re: The power on/off enigma..
 

If it is a timing problem, then it could be that the the timing values they use on specific chip initialization routines fall right on the edge of the chips tolerance levels. Therefore, some chips will have tolerances that fall on one side of the line, others that fall on the other side. That also explains why in some cases users have to leave the battery out for an extended time -- it gives the chips enough time to cool down, which puts them on the proper side of the tolerance line.

Re: The power on/off enigma..
 

It was suggested that it's a timing problem in omap initialization. If there's some kind of race condition in the code, then it can be VERY timing sensitive, so speeding up or slowing down a component, even by tenths of microseconds (as would be the case with temperature changes) can make the problem appear or go away.

Race conditions are an easy mistake to make, and can be very hard to detect or identify. Once identified, they typically just require some extra protection in the software (usually some kind of synchronization object like a mutual exclusion lock (mutex)).

Re: The power on/off enigma..
 

ah... software AND hardware combined, along with environment. Probably explains why not everyone is encountering this. But I've been keeping my pre-production N810 fairly warm (I tend to use it here by the fireplace) and no issues with power. So it looks like my device can avoid the fridge. ;)

Re: The power on/off enigma..
 

Fascinating...

Re: The power on/off enigma..
 

Yes, there is, a software boot, now even with a small utility program.


bun

Is this The power on/off enigma?
 

Ive had my N800 from buy.com since mid November. I had no power on issues until the beginning of January. Once or twice I was able to reboot by removing the battery. The most recent time nothing seemed to work, long press the button... again after 3 minutes, removed the battery, again for 2 hrs for the drm (even put it in the fridge for this step), and then plugged it in waiting 12 hours for the charge icon. All with no luck.

The one thing my unit did that seems different from the power on enigma, is my screen wasn't blank. I would get the White Nokia screen like on normal startup, but no progress bar not even after hours. My question is, when people describe the power enigma the say the screen is blank. Is this the same enigma?

For what it's worth, the way I finally got it to boot was to re-flash. The wiki mentioned the flashing didn't fix the problem, but at least it let me boot up. I'll try the softboot method to avoid issues in the future.

It seems the power problem is practially solved, but I had my hunch that it had to do with some program I had installed, maybe VNC or weather.

Re: The power on/off enigma..
 

odd, shutdown -r now, worked a few times but once only went to a black screen (with backlight). It finally shutdown by holding the power... I had to pull the battery to restart.

I'm curious; what is the difference between 'shutdown -r now' and 'reboot' ?

Re: The power on/off enigma..
 

Blind leading blind.......:o, i'll try.

Technically they are the same, both reset the system to power on status without the hassel of hardware power on, unless the tablet is frozen or in a twilight zone that cannot be brought back. I think the software reboot, which is equivalent to the "three finger salute" of the M$, CTRL-ALT-DEL, is actually missing from the power button menu, "Lock touch..., Offline mode, Lock Device, Switch off." I have added the little button on my screen and now I just click on it to have a reboot. I love it.


Oh, pls cast your vote on the power on/off pull, here, http://www.internettablettalk.com/fo...ad.php?t=15129. Thanks,

bun

Re: The power on/off enigma..
 

Well from xterm 'reboot' command seems to do the same as 'shutdown -r now'. I wasn't sure if there was a significant difference, but reboot is shorter to peck out.

If post 186 is the instructions to create the reboot icon, I might just wait for it to be fixed.

So is the white Nokia screen the same issue, or do people usually get no response?

Re: The power on/off enigma..
 

I too would like to know if this is it. I get the same power-up condition: white screen with "Nokia". After several minutes of this, I play with the power button and it'll finally continue with the progress bar at the bottom. If I don't intervene, it stays on that screen forever. I rarely turn it off, so it hasn't been a big problem for me.

Re: The power on/off enigma..
 

Ugh, now my replacement N800 is having issues.

I left it on this morning with the battery indicator showing 5 days' usage left. It was untouched all day, and when I got home and checked it, the screen was black. I plugged in the charger, and got the white screen with the little green battery thing in the middle (no indication that it was actually charging). I hit the power button, and it powered up, BUT...the battery indicator is missing from the icons at the top right of the screen.

I left it plugged into the charger, held my breath, and turned it off using the power button. I turned it back on, same thing as above. I tried a search and did not find anything mentioning the battery indicator disappearing. Ideas? What the heck do I do with this thing now?

(Running OS2007, BTW.)
