ZTE A2107A-F would not start - how to reset the PMU?

Picked up this little pill about a week previously. was surprised to come back and see that stop you it, not just sleep. Does not start. Tried to load all night; still no go. Called Lenovo; They said to unplug the device and press the power + volume-to top for 30 seconds, then try to connect again to. Still no go. So I packed it in its box to return to the store.

Then I thought what the heck; There are only three buttons; could try as well to the other. So I held the power and volume-* down * for 30 seconds. Now he is in charge. Don't know if I just need to be more patient after trying to reset the time Manager the first power or if power reset key combination really use volume down instead of volume upward on this device.

In any case, I also found little information about this handler to be able to put it back online (it is not yet in the HMM) I thought I'd post here my experience even though it is far from confirmed. Does anyone here have more information?

I had the same thing happen the first day I got it. There is a setting button not labeled in the removable section at the back - it's just below the camera. I pressed it with a toothpick and it still works (and so does my heart!)

  • My Live View would not start or start...

    Had this problem until I saw all of a sudden screen cleared and I could not start no matter how hard I pressed the buttons. In order to reset I took it to the store I bought. The display took the piece and after almost 2 days he returned saying that COMTEL would not cover up for accessories. I called the service center and asked how when offers a limited warranty, they are supported. This gentleman had no answer, but that he would accept neither of my room. Instead he suggested me to get a replacement from the store, I bought. As we were talking about the issue, the display has tried to load my mode live view and the red light on to my great surprise, which indicates that it worked. Then he started to initiate and work. When I got home, I got to know the mode Live View has had an update, I did. 2 months after there was no question too... But still today, after a full charge, it would not start again. I tried to plug into my laptop to update the software, but my laptop indicates that the USB malfunction, indicating that the Live View mode is a.

    I don't know what to do... I love my Live View... Its great use while driving, on a session and in places outside, where the silent noise your cell phone ringing...

    But, I think that the problem starts, if we have to charge the unit. Which could be considered if you are developing a software update for the same.

    Sorry to be too eloborate... Thank you for your time.

    First of all - welcome to the forum!

    Where are you from and how old is your LiveView? All the accessories are getting 12 months warranty on most of the markets (6 months in some markets).

    It might be that the service contracted by your dealer Center isn't HVC (high volume Center). They should, however, help and if so send the LiveView to a service center that allows to fix it.

    You can try to contact local support Office and ask for a service center that can fix your LiveView.

  • Uninstalled emet but after the applications would not start.

    Uninstalled emet but after the applications would not start. Internet Explore tries to start but flashes and disappears, even with Excel. Word starts but gets an error when you try to save. Lucky got Google chrome from another pc and installed so I can at least access the internet. Reinstalled Explorer, office repaired, cleaned the registry, but still no start. What should I do?

    A moderator has moved this thread to the programs Windows of Feedback Forum Forum.

    tried, nothing worked so I uninstalled office and re-installed from disc. Explorer 8 still does not work, but I uninstalled a with explore 7 updates and automatic update started and explore 7 worked. Thought I'd try installing explore 8 new. It worked, even if it failed with the Download Manager. Now all back to normal. I would be careful about the use of EMET, unless you know exactly what you are doing. Not a lot of faith in either the Download Manager.

  • NB100 no usb not power - how to reset

    The NB 100 has 2 usb ports on the right side. I tried plugging in an external cd drive and got a box with red indicator of the background task bar indicating something on the device of drawing too much power and that the supply would be stopped.
    Since then the usb ports 'appear' dead. Nothing I plug is recognized by the NB100.

    It is said in the user's manual if it is found an overload of the power to the usb ports can be stopped. However, it does not say how to reset ports IE power to 'em.

    The card reader and the usb port on the left front work yet.

    I tried the update of the BIOS to the latest 2.10, affecting all the parameters of the default bios with F2 at startup and even bought "Device Driver" to make sure that all drivers are up-to-date.

    Can anyone help? I don't know there is a simple answer but just don't see it.

    Ideally, I would like to avoid having to reinstall XP because I do not have the disk and the hard disk does not appear to have a XP partition.

    Help!

    Hello

    In your case, I recommend to remove the /hub of /controller of the USB port on the Device Manager.
    Simply go to the Device Manager, expand the area of USB controller and remove all the devices that are available in this area.

    After restarting again, the system (Win XP in your case) should recognize the USB ports and the driver must be installed again.
    Then restart once again connect a USB device and check if it can help

    Just for info: USB 2.0 ports provide 500mA so in some cases the external USB device would not detected when this device would need more than the usual 500mA. In this case this device must be connected to two USB ports using a USB Y cable or use an external power supply, as do some USB hubs.

  • Equium won't start - how to access the recovery partition?

    Hi, my sister has a 2008 Equium A200-1V0 with Vista 32-bit, that no longer starts (probably due to damage of rootkit virus). It loads the BIOS but then goes to black screen with blinking cursor.

    F8 does not work.
    F2 goes to Phoenix TrustedCore Setup utility. The Toshiba hard drive and a CD-ROM drive are listed in hand and start in the right order.

    Using F12 I can get it to boot from a Win7 64 bit repair disc that I burned using my laptop.

    However, it does not recognize the operating system or any image or restore points (because it is 64-bit) but he will be responsible for command prompt.

    To * guest *, I can launch Notepad and when I click on file / open and double click on computer it shows 4 Hard drives as follows:
    Local disc (c :))
    Data (d :)) 42 GB free of 54.5 GB
    WinRE (e :)) 1.11 GB free of 1.46 GB)
    Boot (x :)) 29.0 MB of free space of 31.5 MB (which is used by the repair disk)

    So the C: drive is listed, but without ability.

    * CHKDSK *.
    CHKDSK c: /r and press return

    «The type of the file system is NTFS.»
    Unable to determine the status and version of the volume. CHKDSK is abandoned.
    Cannot transfer messages saved in the journal of the events with the 50 State.

    * Run TESTDISK *.

    Analysis:
    Size of the partition start end in sectors
    1 P Windows RE (store) 0 32 33 191 89 26 3072000
    2 * HPFS - NTFS 191 89 27 7477 118 1 117051392
    3 P HPFS - NTFS 7477 118 2 14592 190 62 114307072 (data)

    * = Primary bootable
    When you perform a quick search, then P - list of files, the second partition it reports:
    "Cannot open the file system. Filesystem seems damaged. »

    So what I want to do is boot to Windows restore to drive E.

    My question is for Toshiba experts: If F8 does not work how to use the recovery partition?

    Laptop is:
    Part number: PSAF5E-002005KS
    Main features
    -Intel® Pentium® Dual-Core Processor T2310
    -Genuine Windows Vista® Home Premium Edition

    -15.4 "WXGA TFT display 1 280 x 800

    > THIS ISN'T MICROSOFT, TOSHIBA, AND GOOD PRODUCT DESIGN.
    I really put t know that should do better than to place the Microsoft sticker at the bottom.
    This product key and sticker on it's just proof that you purchased the machine with an operating system preinstalled and legal active OS version. This key belongs to original OS (recovery image) that you got with your laptop and it is not a kind of universal key that you can use for the activation of the operating system if you have made the decision to install the clean version of the OS.

    In General, this key is totally useless. While your computer you've got legal copy and this version, that you can install so often desired. It must not be enabled.
    > So my question still remains: can I recover my Toshiba laptop using this restore partition?
    If you want to recover using the Toshiba recovery image response is not. Cannot start HARD drive recovery facility.
    > Even with a dvd of Windows Vista is genuine, I can't reload the OS
    In my opinion you need make the clean OS installation using the clean installation or order original Toshiba Recovery disk on https://backupmedia.toshiba.eu/landing.aspx disc and install original (already active) recovery image.
