I have TB-J716F. I was using the keyboard properly last night. I just noticed at this moment that neither the keys nor the touchpad stopped working. I tried factory reset but it's still not working. The tablet can detect if the tablet is being connected (productivity mode), aside from that, no response.
Can anyone help?
Try Ctrl+Shift+T Lenovo has some weird key combinations that can turn off the Touchpad or keyboard (I guess) on hardware level, so a factory reset won't help. Try to think, what key combinations have you been using, if my suggestion doesn't help.
I already tried ctrl+shift+T as I've accidentally disabled my trackpad before, however that combination still doesn't work right now.
I'm not sure if there's a key combination that would disable the keyboard entirely.
Have you looked for corrosion/gunk on the pogo pins? I dunno if they're only used for power or power/data, but mine were worn when I got the pad. Just a thought I had.

When I wake the polaris up, it seems that the left button (the one in the wheel) is permanently pressed until I press another button. I have to do this in order to unlock the device, as the button is pressed I only get the message "Press cancel and then unlock".
This happens every time I wake up the device and sometimes when I am using it in other situations. It is almost unusable in this state.
I suppose it is a hardware problem. Any ideas for a way to fix it? I wouldn't like to send it to service, but I am fearing this is the only chance I have now. Any help would be appreciated. I have already switched it off, and also removed the battery for a while, but I have the same problem when I turn it on again.
This has happened to me for the first time yesterday. The device has not fallen to the ground any time since I have it (since February). I only carry it in my pocket.
Thanks for your help.
ah, I forgot to tell you. When the button stops being pressed (because I have pulsed another one) it doesn't work anymore. If a press it, no effect, the cursor doesn't move to the left...
I have read in another forum that someone who had a similar problem with the wheel managed to solve it by doing a hard reset and by restoring a backup done before the problem. He stated that using the option "erasing memory" didn't work and that he had to do the hard reset by doing "gps button + ie button + soft reset".
Here is the funny thing. I cannot do that kind of hardreset. Why? Because as the left button seems always pressed the confirmation screen in which you must press the send button to perform the hard reset, never appears. I guess it is due to the cruise which detects that the combination of buttons is no good or because the confirmation screen is shown but as the left button is pressed, you do not have enough time to press the send button (I don't even see the screen).
Is there anyway to perform the hard reset in another way? Thanks for your help...
Well, my cruise works fine now. What have I done? Nothing. Maybe it was a hardware problem in the contact of the button (some dirt or whatever) and now it is working. I don't know, although it wouldn't surprise me if it were software (I had a similar problem with the vibrator in a Mio A701, two days broken, got to work after that and never again failed). I just used the bluetooth and received a couple of calls.
Now I can hardreset. As the button is no longer permanently pressed, the combination of buttons works. Although I haven't pressed "send" to actually do it, since it seems fine.
More here if it fails again, but as I told you I read similar problems in the wheel in another forum...
Hey, i was wondering anyone else was having this issue.
I have the Tf700 with the TF700 dock and everything was working great until recently. All of sudden now some of the top row of keys do not work/dont do anything when i press them. My: wifi switch key,bluetooth key, turn off touchpad key, and the screen brightness keys do not work. All the other keys on the keyboard work. Ive only had this tablet and keyboard for 3 weeks. Ive rooted and unlocked and its been working perfectly fine until this morning i went to turn off my touchpad, since it gets in the way of typing sometimes and it wouldnt turn off when i used to the Touchpad off key. Is there anything that i can do to fix this issue?
Try rebooting your tablet. Happened to me once, too. A reboot fixed it.

i tried that and it didnt work. I finally figured out what was the problem. I accidently turned off com.asus.keyboard process when i was editting my start up programs and disabling certain ones. So once i reenabled it, it worked fine
Thanks for your help though
Hi I recently got a chacha from a friend and certain keys don't work as intended like
pressing d gives me five and the back button makes question marks.
The key still work so I'm wondering if there is a hardware calibration tool
For the keyboard, I have tried resetting the phone and they are still messed up.
Thanks!

I also have this problem, but only when I have the phone in my pants, and creates moisture in the keyboard, especially in summer.
I brought the phone to help with a problem with the green and red buttons. Them I have fixed the problem, I have recalibrated the phone, but the problem of crazy keyboard will occur.
Thanks for reply but..
Thanks for reply but the think is the problem is not disappearing and I cannot login into google and other services because of the keyboard.
The phone has probably been dropped many times so i think its a hardware problem hence recalibrating the keys to what they should be doing may help. I have tried button mapper and tools like that but it requires root access or limited funtionlity
A few months ago the keys on my Asus TF300T keyboard base stop working. That is, it does not accept any input via the keys on the keyboard. The trackpad still works though, and I can still charge the keyboard base and charge the tablet from the keyboard. I've tried gently lifting and wiggling each of the keys to see if something was perhaps stuck, but without any luck. I've also tried generally mashing the keyboard to see if I could ever get any response from the tablet, but nothing works.
I have the right sort of screwdriver for opening it up - is there any point in doing so? And what would I be looking for?
More generally, *why* would the key input suddenly working? Is this something I'm likely to be able to fix or not?
Hi guys,
I am experiencing the wierdest thing on my brother's Xperia Z3.
2 days ago, the phone randomly stopped showing images on the screen, but the backlight would still switch on and off as normal when pressing the power button. If the phone is restarted in this state by using key combos, the Sony logo won't even show up. This problem started intermittently, but now it does this for a much longer period. The issue would usually occur after the phone being locked, or if it were being used, the screen would show horrible distortion on the bottom half and become non-responsive until the screen switched off and any attempt to switch it on would be make the phone behave as described earlier.
I used to be able to make the image work by plugging in the USB cable, but this method seems to have stopped working, or at the very least has a really low success rate. I have tried all the soft reset methods: Power+VolUp, yellow button in the sim tray, none of those work for me.
I have just stopped short of reflashing the phone with Flash Tools.
Has anyone had this problem before? It is really confusing me as to whether this is a software or hardware issue.
Any suggestions?
I reflashed the phone using Flash Tools and the phone is still behaving the same way; just the backlight is turning on. Besides that, the phone seems to be making the correct noises and responding to the USB cable. Anyone have any ideas? Could it be the screen itself? I'm worried that it may be the motherboard.
Ok, I found something that works. If I hit the device with my hand on the back or the screen a few times, it seems to bring the phone back. My suspicion is either a loose screen connector or something on the motherboard. I'm not really comfortable with opening the phone up, so this is going to be my go-to solution. Hope this is able to help someone.
