Brightness ThinkPad tablet lockscreen bug

I searched around, for those who have a similar problem to mine, but I can't seem to find discussions that match.

My TPT seems to have a problem where the brightness of the display is reset to zero after unlocking the screen to about 70 or 80% of its maximum value.

It's extremely frustrating because it influences significantly the battery life, and I often use my slate during courses where I need to be able to count on not to empty my entire battery in a few hours.

Anyone know if it is a common problem, or so Ive just forgot something? I set it to auto brightness offshore and have tried everything I can think of, but nothing helps. Would be nice if I could avoid changing the brightness after each single release.

  • ThinkPad Tablet 2 random Crash of the common OS.

    Nice day.

    I have a new Thinkpad Tablet 2 with windows, Non-cryptage, 32 gig.

    I have only one question, random os crash so far.

    It happens anywhere, usually once a day.

    While it is plugged in or on battery, or offline.

    It happens on different application, desktop, browser, email, to the login screen.

    The only thing that seems to be constant memory, is that it occurs when the on-screen keyboard appears.

    All updates are done, I do it manually to keep track of it and ensure that it is done correctly.

    I love this product, I do not understand this bug are expected on new devices.

    Whenever it happens, I'll post in detail. I am in the island this will help Lenovo is the problem earlier.

    Any ideas on how to solve this or if any information that someone thinks that it might be useful to find the problem, please let me know.


  • ThinkPad tablet 2 slow/fast load on different occasions

    Hi the Thinkpad tablet 2 users.

    I know there are a lot of bugs were found so far. For me, I had to return once because of the incapbility of the digitizer on this tablet. I got a new one seems flawless, but I just found something that might be quite annoying but interesting at the same time, as the title suggests, so here are the details:

    -If I have my Tablet completely off and then plug the micro usb cable to recharge (mode ca, or what is called: wall plug), after nearly 9 hours, the battery % is 30% ~ 90%, which is extremely slow.

    -If I turn on my computer while charging and turn it off again, it loads much faster, from 30% to 100% in less than 3 hours.

    -In a similar to the one above, if I let it load mode 'sleep', she also go much faster

    In conclusion: there seems to be something in the window 8 who control the load, it seems that whenever you leave your window to know that he is in charge, she goes much more quickly than if you have it completely turned off and plug the cable to recharge. I need more time to test this theory, but if you have the same experience, please leave a message here, even just 'me too' or 'here '.

    Best,

    Tuan


  • ThinkPad Tablet 10 1nd Pen Pro

    Hello

    can I use the Thinkpad Pen Pro with a Gen Thinkpad Tablet 10 1nd?

    Thank you

    No, sorry, you can't. The Pro of the pen of Lenovo is an active pen (it has an AAAA battery inside) and uses the AES of Wacom technology.

    ThinkPad 10 uses technology of Wacom EMR and the pen of Lenovo (part No. 00HW280) is a passive EMR pen. Pens of third parties who use Wacom EMR technology should also work.

  • Windows 10 scheduled for Thinkpad Tablet 8 products?

    Can someone close to Lenovo tell us, if Lenovo intends to extend drivers and support for Windows 10 our products of Thinkpad Tablet 8?

    Obviously. Microsoft is responsible to provide the Win 10 update, and they said they would free within the first year of existence of all devices on Windows 7, 8 and 8.1. That is why it would be appropriate that Lenovo would finally win 10 support for its existing products as well, in addition to their new product preloaded with Win 10 lines. We have several more months to go, so be patient...

  • ThinkPad Tablet 2

    Lenovo ThinkPad tablet 2 does support Linux? Fedora running on it would be cool.

    It should because it's x 86 platform. There are mixed reports as the graphics chip, I believe that atoms in TPT2 have VR graphics, not the intels so support driver so that it is not very good.

    Screen touch supprt improved lately too so it shouldn't present a big problem.

    I'd go with something lighter than fedora.

  • ThinkPad Tablet 2 set button pen

    Hey all, I have ThinkPad Tablet 2 with the Wacom digitizer and an active stylus. The stylus a button on the side which the manual says is for screenshot. I would like to configure this button to be identical to a right mouse click on the button (I'm not a fan of the tap water then hold list drop-down functionality of the right mouse button trigger). To make this I:

    -Search 'calibrate' in Win10

    -went to "calibrate the screen for pen or press ENTER.

    -On the dialog box opened, I clicked on the tab 'other '.

    -J' clicked on the link "Go to Pen and Touch" under "configure your pen and tap Settings in pen and touch.

    -An open windows error dialog box that says:

    "Tablet and pen settings is not available. For assistance, contact the manufacturer of your tablet PC. (error = 0). »

    So here I am and here are my questions: why these settings are not available? Is there another way to configure the associated stylus button action? Thank you!

    Problem solved. I uninstalled Windows 10 and reinstalled and the pen settings are now available and more screen auto-rotation, now working as well. I find this strange because I makes no other changes to the Tablet and I was running any other software before, during and after my first upgrade of Windows 10. I guess an update has been published or there was a quirk in my initial upgrade of Win10. In any case, all's well that ends well

  • Memory, ThinkPad Tablet 64 GB Version 2

    2. Type "Recovery" and then press on to find settings

    3. click on 'create a disc of Recvovery '.

    4. follow the steps in this wizard

    5. in the end, it will give you the option to delete the recovery section on the hard disk to free up space now that it is saved to USB.

  • Issue of ThinkPad tablet 2 Factory Reset reinstall Windows

    Please help me. I have problems to reinstalling windows on my thinkpad Tablet 2. I have a long enough thread explaining my problem here, http://forum.tabletpcreview.com/lenovo-ibm/62633-thinkpad-tablet-2-factory-reset-reinstall-windows.h... if someone could help me I would be very grateful. I'll copy and paste the thread here, if I have to, but it's just easier to copy the link.

    Fastest salvation,

    I had similar problems to you with a number of our TPT2s. They are really picky when it comes to boot from an external support. Here's how I got mine to (possibly) regularly start on external media. However, one thing to note is that, in order to recover Windows 8 on it, you're either going to need disk recovery Lenovo or an installation of Windows 8 of your own disc. I have no idea if the drivers listed on the Lenovo site will work with anything as old as XP, although I remember some Windows 7 see so if you have a Win7 disc you might try that.

    1. disable the Secure Boot UEFI in the BIOS. [BIOS |] SECURITY | SECURE BOOT | [* Change the secure startup flag ' disabled]

    2 get some kind of separator/hub USB so that you can plug your external DVD drive with a keyboard (Microsoft still require you to "push any key to boot from CD" and touch the screen does not count).

    3. with the drive and the keyboard is connected, set the boot order in the BIOS so that the CD/DVD drive is the first boot option. I also push the Windows boot manager at the bottom of the list if it is there. Do, but I'm a superstitious Guy and save the changes.

    4. as long as the DVD drive has adequate power (need an external power supply. He cannot draw enough power from the USB port of the tablet to run) and you have a Windows disc 8/7 in the drive, you should now receive the message "press any key to boot from the CD-ROM. Press a button and it should... Finally... it takes much longer than any normal device... starting in the installation menu.

    Each step of this lasts longer than you expect. For example, it takes an age for the message "Press any key" is displayed. It just sits there with a black screen and the DVD blowing away.

    That's how I got mine to work in any case, best of second chance.

  • ThinkPad Tablet 2 - fingerprint reader

    Hello

    many ads and a first version of the technical specifications, was told that there is an optional fingerprint reader. It is somehow option has completely disappeared from the Lenovo Web site. At first, I thought that this option could simply not be in the final product. Now, I read again about this in an Australian magazine.

    I was talking about the Lenovo sale cat today and I was told someone else that is not available right now, and it is not clear if it will be available in the near future and one that Lenovo still offers this option.

    For me, it would be good to know if you have to wait a few weeks. I don't really understand the information policy of Lenovo.

    Jonas

    ThinkPad Tablet 2 doesn't have a fingerprint reader option.

  • 1 BATTERY ThinkPad Tablet

    As the title suggests, I think that I need a replacement battery for my Thinkpad Tablet 1838.

    I went for 3 months and came home to a dead tablet. It does not take a charge, used to power over everything.

    Replace the battery an option?

    Thank you in advance!

    I suggest that you call Lenovo support and ask if they propose replacing the battery and if so how much they charge.

    Be sure to tell them why you think the battery is dead. Although it is unlikely, perhaps they can offer a way to revive.
