U430 power off while on battery

Hi,
I have had my Lenovo U430 touch for about a month now, and have noticed a problem with it. Sometimes when I leave my Lenovo u430 touch alone (with full battery), and sometimes it will just power off without me doing anything. It even happens occasionally when I dont use it for a few minutes while im working in front of it. 
It is definitely a power-off problem for me, rather than hibernate/sleep as my programs are no longer running when I turn it back on.
Hasnt caused any lasting damage as yet but am worried it could happen while im working on something important. 
Happy to give more info if needed (will need instructions on how to get it though - im not that computer-savvy).
Thanks for any help.
Solved!

Hi Olaf9500,
Welcome to Lenovo Community!
As per the query we understood that you are facing an issue with system turn off when the system is in idle in your U430 laptop.
As you have mentioned for the drivers please check the below link for the drivers.
Click here for the energy management drivers if the operating system is windows 8(both 64bit and 32 bit).
Click here for the energy management drivers if the operating system is windows 7(both 64bit and 32 bit).
If you are using windows 7 then go to start search type power option, under on battery there is option for turn off the display, select never option and check for the issue.
Also there is option for the sleep under the power option select never option and check for the issue.

    There are no user serviceable parts in an iPhone. Since you
    made an unauthorized repair to your iPhone, you will have to
    seek assistance elsewhere.
    Google or ifixit.com may provide some direction, but you can

    but it is what it is.

  • Macbook randomly shuts off while on battery power.

    I have a 13-inch Macbook, Late 2008 model, using iOS Mavericks. While on battery power, the laptop will randomly just turn completely off, despite still having plenty of battery power left. I know it's not a calibration issue where the battery is dead but appears to have charge left, since I'm able to turn the computer back on again and continue using it.
    Battery info:
    Charge Information:
      Charge Remaining (mAh): 606

    First try the SMC reset appropriate for your model: Intel-based Macs: Resetting the System Management Controller (SMC)
    The information you posted says "Condition: Service Battery" - that likely means you will need a new battery sooner, rather than later, especially if an SMC reset doesn't help the situation at all.
    In any case, when new, your battery likely had about 4400 mAh (milliAmphours) Full Charge Capacity.
    The Full Charge capacity is down to about 60% of original capacity 2600/4400
    A direct replacement from Apple is $129, installed.
    Any popular search engine will provide a list of less expensive suppliers, but I cannot recommend any, simply because I haven't used any non-Apple replacement batteries recently. My single experience with one lower-cost supplier for my polycarbonate 2007 MacBook (replaced in 2010) was that the cheaper battery needed to be replaced again within a year. Your mileage may vary.

  • MacBook Shuts off While Using Battery Power

    Hello!
    I have a white 13" MacBook from 2006.
    But whenever I try to just run the MacBook on battery power, it shuts off within
    1-3 minutes of use (Mainly using Safari).
    I tried to reset the SMC, and changing the battery to a new one, but the problem
    still persists.

    When we switched the battery, the cycle count was 216 with the new battery.
    But when we switched the batteries back, it was still a cycle count of 216.
    We also tried to call AppleCare, but they didn't help very much...
    Is there a defective part in my MacBook?

    Never mind with the question...
    My dad mixed up the batteries and put the old battery back in the
    old one, and the new battery stuck in the new one... =P
    So, I tried switching the batteries by myself, and guess what?
    I'm using the new battery right now - just on battery power!
    (And it's not shutting off! =) )

  • MBP simply switches itself off while on battery

    Hope to get some idea of what's going... basically yesterday while I was using my MBP on battery alone, the computer simply switches itself off out of the blue. So I check the temperature and everything seems fine. I was using it with video card in the "better battery life" mode, so I didn't think it was overheating. So I switched it on again. After starting, after a few minutes it went off again. I gave up and didn't switch on again until connected to the mains, and it is on until now without any problems.
    Has anyone experienced this before? Any ideas of what's going on?
    Thanks

    I have experienced this before. I hate to be the bearer of bad tidings, but this is a sign that the battery is dying. You may well find that the time before this happens reduces until eventually you will get a few minutes at best.
    You do not say how old the MBP is or if this is the original battery. My old one (recently replaced) went through the first battery in just over a year; and then a year later the second went too. I changed how I used the third one. I had relied on mains power when I could before. With the last one I used battery whenever I could and charged when necessary.
    Make sure the battery is calibrated but I am not sure that is going to help.

  • Ideapad s400 touch bios or other hidden power management while on battery? or battery just weak?

    Hi,
    I have problems with performance when unplugging my ideapad s400 touch, and it does not seem to be related to windows or intel graphics power settings.
    Example, while plugged in with full battery (not charging), I can play Skyrim at 600x800 with 28-30 fps (all shadows turned off and with reduced textures, in case you are wondering how that is possible)
    But when I unplug, or the computer is charging, the game will be only barely playable at  480x640 with 18-26 fps (besides res. of course same settings).
    In both cases, the intel graphics options and in the Lenovo Energy Management is set to the high/max performance settings.
    So I am wondering if there are some hidden Bios power management or some other hidden power management going on, when it is unplugged or charging?
    Or if simply the battery can not deliver the same juice as when it is plugged in?
    Thanks for any help,
    L

    hi x8lars,
    Welcome to Lenovo Community Forums!
    Can you try changing the power plan on your system to a High Performance Settings,
       Also check the Advanced power settings and make sure that the Maximum  Processor start and minimum are set the same with the Plugged in.
    Let me know your settings,
    Cheers!

    MY phone turned off while texting battery at 72%. I tried turning it on but screen stays black.

    First, try to reset the phone by pressing the sleep and home button for about 10sec, until the Apple logo comes back. You will not lose data by resetting.
    If this does not work, connect in recovery mode, explained here:

  • Sudden Power OFF - Satellite A110-195

    Sudden Power OFF My Satellite A110-195 suddenly power off while using on A/C power, it happens many times a day after 1 to 1 and half hour use, the room temperature is 20 to 25 degree Celsius.  Again I have to push the power button to switch on the laptop.  Why its happing?
    Solved!

    The classic cause of an uncommanded shutdown is overheating.  The system shuts down to prevent damage.  Had your power adapter failed, the system would continue to operate until the battery was exhausted and in that case you would get low power warnings before shutdown.  If the system is under warranty, the best course of action would be to take it to a Premier (emphasis on Premier) Authorized Service Provider.  If it is overheating, they will open it up, clean out the accumulated dust and dirt, remove and clean the processor heat sink and reapply thermal grease.  If it's not under warranty, you can do much the same yourself - or at least as much as you are comfortable with.  At the least you could blow out the air vents with a can of compressed air and see if the situation improves.

  • My iphone will not power off

    My Iphone 4s will not power off and the battery is draining with a couple of hours ? Help please

    Try an iPhone reset first which is done by pressing and holding the home button and the sleep/wake or on/off button simultaneously until you see the Apple logo and then release. This is similar to a computer restart.
    Try powering the iPhone off again after doing so.

  • Windows 7 does not power off properly with bitlocker enabled

    Hi
    I've got an X200T and installed W7 Enterprise. Things are mostly working fine but i ran into a problem with bitlocker.
    When shutting down, the shutdown process but does not power off my laptop battery: bluetooth light stays on, fan stays on, hardrive stay on.
    the funny thing is if i force the complete shutdown by pressing the ON/OFF button for several seconds, the next startup run smoothly, the system does not detect any wrong shutdown.
    i found a threat relative to this problem elsewhere but nothing on this forum.
    i'm wondering if any of yours are able to run W7 enterprise 32bits + X200T + bitlocker without any problem
    Let me know
    cheers

    Hi,
    I can not tell you about a correlation between your problem and Bitlocker, but what I can tell is that I also have this issue (from time to time - my system is seldom shut down ^^) on my machine, which is a T400, without using Bitlocker. So maybe this is a BIOS defect, as I don't remember this happening before BIOS version 3.
    OSs under which this happened are Vista x64 and Win7 x64.
    Greetz!
    M.T.

  • Random restart instead shutdown and power off in bios

    Dear all,
    since some time my Thinkpad T410 randomly restarts instead doing a requested shutdown. Also there is a random power off while POST when I power on the system (I not noticed any relationship between both problems except the date since they occur - maybe a system update, but I'm not sure).
    I'm running Linux 3.1.2-1-ARCH with thinkpad-acpi kernel module and laptop-mode enabled.
    I also tried Windows and Ubuntu to assure that this problem is not hardware related and I never experienced the problems with both tested OS's.
    Has anybody experienced similar problems or a clue where to start looking for problems?
    Cheers,
    Martin

    By now, i think i solved the problem with a clean arch installation. I know, it's overkill, but I can't figure out the cause of the randomly appearing problem.
    @albLinux: If you have this problem when rebooting each time, try google or have a look here:

    Sounds like you need a #1SMC Reset
    1. SMC reset
    >>Instructions to reset SMC
    Disconnect other non-Apple and external hardware except (if applicable) a mouse and keyboard until your finished repairing your machine.
    Problems solved: Fans blowing with no activity, machine is not booting, power button pressed and nothing happens, problems with indicators, Magsafe has wrong lights, battery is not charging, monitor and graphics issues etc.  If the battery is not charged (from like letting it sleep too long), let the Mac charge up awhile afterwards.
    Will not hurt the machine resetting if it's not broken.
    Other related hardware problems (optional):
    Check battery status: Hold option/alt key down while clicking on the battery icon in the menu bar, top right corner.
    Magsafe: Use the correct/matching power supply charger with your Mac, not a less powered one from another Mac.
