[Q] screen activation - Eee Pad Transformer Q&A, Help & Troubleshooting

1st, I'm spanish I'll try you understand what I say
I see that the tablet with the screen off (locked) can be activated without pressing the power button. Only need to put "near the dock"*
*making like you open the tablet+dock, but is not needed that the tablet was connected with the dock, I dnt know if someone else was noticed that... but I'm a bit curious about that and i want to know how its work? (magnet?, gyroscope?, magnet+gyroscope?) if someone knows it
and I say it to other people that dnt now this, THANKS
SOLVED MISTERY!
Like some says here its a magnet near the backspace key, exactly the "¿/¡" key
here is a really good cover mod idea: http://forum.xda-developers.com/showthread.php?t=1507548 thanks to MrNago

nobody has any idea?

I think there is a switch in the hinge maybe? Seems that would be the easiest way to have the screen turn on while opening the lid while its on the dock.

I test one more time and I noticed that the system is only at the right side of the tablet and dock, like u see in this image. And its not needed any contact, but it need tablet and dock really near.
I think is a magnet system, but i havent any magnets at home to make a try...
edit: i have an error in the image, looking the camera i can see that the tablet is in the wrong side, we must see the camera down. Not at the top like in the image xD

I see nothing in this disassembly to make this activation, this is curious, i want too know how it works

turning on via opening.
i tried looking using a magnetic viewer screen there are several places in the screen and in the keyboard that show magnetism, on the screen the two speakers are the main places and in the keyboard below the backspace key is quite strong as well.
i tried replicating the action using a strong magnet but i could not get it to work only when help above the keyboard does it work so there may be more then one place it looks at, i will try again when i have more time and then post results.

Interesting discovery! I don't thnk anyone actually tried this, though many speculated there were magnets in the base, many users said (and I agreed at the time) that the mechanism to wake the device was located in the hinge, though having a function like this actually does make more sense than an actual hardware switch that could fail at some point.
You should make a video and I will add this information to my epic noob thread!

thanks for replies, i tried with a small magnet without results, and try in other positions with the dock and negative results too...
I'm sure that the magnet of the backspace key its the "switch" or one of them, they are 2 maybe....

Guessing here, probably not just a magnet, maybe even an RFID chip of some sort..

Its a magnet that does this. Don't doubt. Believe. Removing the magnet and putting it back in is part of my hard drive soldering procedure.

it is a microswitch in the hinge, all experimentation I have done supports this, the only thing left for me to do is pull apart my dock and take high res pictures of the microswitch seeing as you all seem to need proof of it

Stevie, i did think so as well, but the device will wakewhen placed on the dock and removed even if it is not affixed in the hinges and even if the hinge does not move, i don't think you are getting what poster is saying, i will make a video myself and post to demonstrate.
HERE
Thereis also probably a switch in the hinge as well for sure, but this does seem important information, wonder what the mechanisms in the body of the tf are..i enjoy solid state switches like this

Oddly enough this is confirmed using Paul's ICS and my dock not connected. Totally bypassed the lockscreen. Held it as close as I could for about 5-7 seconds then on came the screen. Tried this at least 10 times (five of which I just was amazed) and everytime opened right up. Nice catch:thumbup:

You guys are right, there is some kind of magnet. For those that doubt it, like I did, try this:
First off, undock the tablet, so that you have the 2 items apart.
1. Lock the tablet, so that the screen is off.
2. On the dock, rotate the hinge outwards, so that you can put together tablet+keyboard without docking.
3. Actually put them together, so that their position is exactly the same as docked, except they aren't.
4. Screen should turn on. Mine certainly does!
Edit: as you can see, there is no connected circuitry between them and the tablet is waking up. Don't know about locking though, but I hope this gets things clearer and Modding nearer!

This is the same way to unlock that Im saying since the first post. Only need to test to know what kind/power/number of magnets or "sensor" is needed

[Q] xoom touchscreen issues?

I got my Xoom (WiFi) yesterday... already noticing some weird touchscreen behaviour.
It seems to me that whenever the Xoom is laid down flat, there's a chance that the device will stop responding to touch presses properly. Instead of being able to press-and-swipe, it acts like I tapped the screen (eg, pressed my finger on the screen and then lifted it straight back off) or worse, it causes a screen press in completely the wrong position. When it starts happening, it keeps on happening, but picking the Xoom up and holding it vertical seems to fix the problem.
Half the time it seems fine laid down though, so I'm not sure if it's just coincidence that it stops working at the same time I put it down flat or not, or that maybe picking it up means my hand is in contact with the back of the screen and this somehow changes some sort of electrical variable in my hands that affects the touchscreen operation.
Anyone else seen the same issue? I'm thinking I may need to take it back but want to see if anyone else has experienced anything similar.
Chris.
ok.. judging by the lack of response on this, I may either be on my own or it's just something that nobody is noticing. I've been testing it a bit more - I wrote an app which can show each touch point on the screen so I can see how the screen press/drag is working. This is what I've found.
Holding the tablet upright, screen presses and movements are fine, however I've noticed that if I hold my fingers in the same place for a while, the touch points will prematurely end.
If I put the Xoom down on the couch, there is a strong likelihood that the touchscreen will become incredibly unresponsive. I have had it regularly show up phantom presses where touching one point of the screen makes it appear as if I have also pressed another point of the screen. I also cannot drag my fingers across the screen - the touch points stay where they are until I take my fingers off the screen completely, or they just disappear right away as if I tapped the screen.
When this happens, if I touch the side of the case with either a free finger or my other hand, the touchscreen starts working perfectly! Seriously! I'm not kidding, I've been messing with this thing almost non-stop for the past coulpe of days and it is consistently doing this. So - couch + little finger on side of case = working touchscreen. couch but no contact with metal case = malfunctioning touchscreen.
If I have the Xoom in Motorola's case, it seems to work fine. If I put it on a table, it's a bit buggy but generally works better than on the couch. Any sort of material seems to send it regularly into crazy mode. The only time I've noticed it doesn't do this is if I'm in contact with the device immediately before putting it down and then remain in contact with the screen.
Could some sort of static charge cause this? Is it possible that me touching the back of the case is effectively allowing it to 'conduct' electricity properly on the touch screen? I'm not all that familiar with how capacitative screens work other than I assume they measure capacitance from your fingers. Maybe a static charge could throw it off. Or maybe I have weird fingers.
Anyway, I'm pretty close to taking the Xoom back now. Just trying to figure out if it's actually faulty or whether they're all like it by 'design'.
sorry
need to post to remove my limitations sorry again
This could be a loose touch controller cable. Someone had similar problems and posted a how to fix this, search for it.
It happens with me too, it's incredible annoying when you are developing and the tablet is on your table for debugging..
Did you find how to fix it?
I have a serious unresponsive issue on my Xoom when charging. I've tried several different chargers, (all from Motorola) with no luck. Unfortunately all the ones I tried where at my house so I'm not sure if its a wiring issue in my house.
I also have a similar problem on my Droid Razr so I'm starting to think its definitely the wiring.
Anyone know about this issue or have any recommendations?

Thats weird.. i owned xoom n droid razr too but i dun have any iissue
It could be a wiring issue (try another house, I guess), but a lot of devices are like that where the touch screen stops being as responsive when it's on a wall charger.

Touch cover issues?

After having a duff sd slot on my original surface my replacement arrived today, all good, left it doing updates and installing my apps for a while, all was well, or so I thought..
The keyboard is now not responding after a while, connected, works, close the cover, open it again, screen doesn't come on, press power button screen comes on, keyboard not responding, close cover, screen stays active, disconnect keyboard and reconnect it and it works again..
Had a quick look through the settings and there's nothing I can see that relates to keyboard sleep or power management..
Tried it on my old surface and its fine :\
Wondering if anyone has seen or heard anything similar, otherwise another tech chat with support tomorrow...
You might want to try rebooting the new Surface, and make sure the connection port where the cover links up is clean, but otherwise I don't know what would cause that problem. I've had cases where the cover wasn't recognized, but disconnecting and reconnecting it fixed that.
Only issue I ever have with the cover is if I remove it while the tablet is sleeping and when it wakes it thinks it is still attached.
It's been rebooted many times so dont think its that, had a poke thru device managet last night and looked for power saving stuff but nothing relavant..
Connectors are all clean and it works in the old Surface.. :/
Maybe the keyboards just missing the tablet it came with lol
Still nothing, hard reset, power offs nothing, have now noticed that the edges of the touch cover are peeling apart at the corners so might get this replaced as well, so far the support guys have been spot on, the device however while really promising just lacks finish :\

Two options....
1. Return the cover..
2. Bring your surface bad cover to Microsoft store and let them figure out what is wrong...
I am very happy with my surface and the touch cover...
I have a 5 second delay sometimes when opening and closing. Otherwise, ref let msft know

I've had 2 bad units now, don't think its the cover as it worked on the first surface before I returned it.
I'll get onto surface support when they are back, I don't seem to be able to raise a ticket on the new unit, touch cover might end up going back as well at this rate...

I've had the same issue with the type cover. Sometimes it works fine throughout. Other times it seems to fall asleep until an adjustment is made.
I've caught the connection off by a few millimeters at times (although that doesn't explain why the initial connection would work), but you can look and check for that as well.
From now on I'll simply restart from the Power button without removing the connection to see if it's really a 100% mechanical issue.
Ha I've had all of these problems you've named
On Live Chat with support now, the MS forums seem to suggest a reset, I've tried it a few times tho, will see if they will fire out another cover..
Right, cover is being swapped out on AR as well now, hope they hurry up and take the hold off the card though, the hold is for more than it would cost to actually buy the bloody thing new again..

Did I break it or is this standard (dock issue)

Well been studying movies on the innards of the TF700T (haven't touched mine yet for that tho!). And I noticed some "brackets" on the connection end of the tablet to the dock, with this I noticed I don't have them on mine.
Now... this wouldn't be a issue but lately the tablet seems to fall out of the dock very easily. It's not that it's loose or anything but well not locked. Not a nightmare, but I had some near accidents due to this several times (picking it up and the keyboard falling off or the other way around). So well it got me wondering, are those brackets broken for me? Or is this standard?

Are you talking about the black plastic plugs that "plug" the connector holes to keep dirt out? Even if you had them you'd need to remove them to use the dock. Some dock/tablet combos do not lock just by pushing them together(well documented here) and you need to manually pull the tablet lock switch into position.

Mine no longer docks securely at all, so I double-sided-taped it to the dock. Known issue, and it happens with little use of the docking mechanism per se. More and more people are reporting exactly this, and ASUS washes its hands in innocence... :S
Make sure the lock switch reaches the end, if not then its not fully secure. Theres a problem with the keyboard where the little tab that the tablet is suppose to push down when docked doesn't get pushed down because it can't reach it. Thats why when you hold the tablet part the dock would fall right off. Use a pen and play with that little tab and you will see the black slot locker. I'm thinking of finding something to stuff it so that when i dock the tablet and the extra thing i add would push the tab down and lock fully.

Both these little black have completely broken off on my dock -- no rescueing possible by pushing whatever other part.

tf101 shuts down when applying pressure to the lower right

All in the title. Anyone have any idea why this happens? It started doing it fairly recently (I've had this tablet for more than a year now) and its frustrating especially when it happens whenever I pick up the tablet
Would seem like a lose connection or something. I'd suggest you carefully open it, and make sure everything is connected properly. If it is, try re-seating all the connectors, especially the display.
Could be a crack in the board / cable come loose / short or earth
Do you hear a rattle in yours? In that area I hear a rattle and my tablet doesn't rotate so I assume that's the location of the accelerometer.

Mine does something similar... It doesn't turn the system off, it just turns the screen off from what I've noticed. So just two taps on the power button and your are good to go I think.

Wireless charging quit

After opening the back of my phone and taking it apart to get a stuck sim tray out, my wireless charging quit working. What could I have done? I did remove the battery, but I made sure to plug everything back in. Was there a connector on the backing that I missed?

Make sure to press the back down toward the upper middle of the back (all around the "S" in Nexus). There's a clip there that must fully seat, or the wireless charging connectors won't make contact. It's pretty common to miss that one.
Note: I think it's actually a bit to the right (or, a bit "beneath" the letter S, when held in landscape), but I can't remember the exact location, so just press down all around that area.

After putting my phone back in its Spigen case, I seen a couple clips came loose. I pulled it out of the case and made sure they were all seated and tried it on the charger again without the case and it still isn't working. I really don't want to pull the back off again but it's looking like I might have to, otherwise I gotta see if I can get the phone replaced through my carrier and hopefully they don't find out the back was off.

Thank you both. When I get home in gonna see what I can do and if it doesn't work I might try the back replacement option before I try to get it warranted.

Judging from the picture in that link, the clip I was talking about seems to be directly across from the flash, just to the right of center (as you're looking at the back of the phone... so, just to the left of center in that picture), so that's where you want to press down to make sure that clip gets seated. (I guess I didn't realize it was that far up.) You can see by the proximity of that clip to the wireless charging pins how not being fully seated will cause the pins to not make contact.

OK, I didn't realize there was a clip there. I'll give it a try. Thanks.
@jt3, thank you so much. That fixed it. Working now. I'm having some display issues though, don't know if it's related. The whole screen becomes a bunch of lines but goes away when I press the power button. I've seen it before and it might be Multirom related but I'm not sure.
And thanks @Henrock11 for providing the link to the picture to figure this out.
No problem. Glad I could help.

Glad to hear. Like I said, it's VERY common for people to miss that clip when replacing the back cover, so I figured that was a good place to start.
Just out of curiosity, what prompted you to remove the back cover? Button Rattling? Weak Vibration?
