Lenovo Z50-70 compatibility issue between power management ....

Hello I got my Lenovo Z50-70 Back in May 2015 and decided to reinstall the OS cause I didn't want the bloatware that came with the computer. I installed the drivers that came with the computer and now I'm getting a power management compatibility issue that I can't seem to find the solution to online. I believe this is part of the problem as to why my computer only charges to 60%.  Some forums have suggested Bios issues but idk how I would go about approaching that issue so if anyone could help me solve this issue, that would be greatly appreciated.  Description

hi sreedhar2009,
Welcome to the Lenovo Forums.
Just to verify, was the machine running on Windows 7 before and you upgraded to Windows 8 via the upgrade advisor?
  - If this is the case then you will need to uninstall the Lenovo Energy Management for Windows 7 from the Control Panel > Programs and install the Windows 8 versions below (reboot if necessary):
For Lenovo G580 (2189, 20150):
Lenovo Energy Management
Windows 8 32/64bit
em8.0.2.5.exe
45.4MB
For G580 (2689, 20157):
Lenovo Energy Management
Windows 8 32/64bit
em8.0.2.3.exe
45.4MB
Regards

    You should check your startup drive as a starting point, if programs are crashing regularly. That's obviously not "normal." Run +Repair Disk Permissions+ in Disk Utility while started up normally. Then, start up from another disc and run Disk Utility to use the +Repair Disk+ on the startup drive, to look for disk directory issues (you can startup from the Mac OS X installation disc to run Disk Utility).
    When this happens, Force Quit doesn't do anything. Any other options?
    You can start the Activity Monitor program and quit processes that look relevant to the app. Sometimes, force quit does not work to quit an app because an underlying process keeps running. Sometimes, the Mac is not able to restart or shutdown normally because an app refuses to quit, due to this problem. It is often difficult to know if you should kill a process, so after doing it to make an app quit, it would be a good idea to restart.

  • How do I fix the compatibility issue between my iPhone 4S with iOS 7 and my Pioneer car stereo? There was no problem with iOS 6, but now I get a message saying "this device is not compatible" and so I can't use Netflix for example. How do I fix it?

    This is a typical response from the manufacturer. Did you try the fix that Lawrence mentioned. When Apple or any other phone manufacturer update phone software, they have the latest Bluetooth installed. It is usually the problem with the radio manufacturer that they devices are using the older Bluetooth protocols. You can try this support document http://support.apple.com/kb/TS3581 and see if anything there helps, but generally it requires the radio manufacturer to update their firmware.

  • Adobe Flash IDE: Migration/Compatibility issues between Adobe Flash Professional CS3 and CS5

    Hi,
    Adobe Flash IDE: Adobe Flash CS3 Professional and Adobe Flash Professional CS5
    I am facing some  migration/compatibility issues between Adobe Flash CS3 Professional and Adobe  Flash Professional CS5:
    I am working on a project that has  been completely developed in CS3 earlier. When I am using CS5 (Flash Player 9 /  Flash Player 10) to compile the FLA files, it is creating some new issues like  some customized radio buttons are getting disappeared while viewing the SWF on a  web page etc.
    So, I would like to  know:
    1) Is there any  migration/compatibility issue between Adobe Flash CS3 Professional and Adobe  Flash Professional CS5?
    2) If yes: Is there any patch  available from Adobe for it?
    3) If no: What could be the causes  and the best possible solutions for it?
    Any help and support would be highly  appreciated. Many thanks in advance!
    Thanks & Regards

  • Compatibility issues between CS5.5 & new macs?

    Hello all. Does anyone know if there are compatibility issues between Audition CS5.5 and new macs? Just got a 2013 MacBook Pro (OS X 10.9) and haven't been able to install my copy of CS5..5, which I've been using on an older mac for years. I've tried both the original installation disc and a download.
    Thanks!

    Depends entirely on the application. You should probably visit the
    individual product forums for details.
    I will tell you this. For InDesign you're not going to be happy at all.

  • Issues between power, usb and airport?

    Well, after having my new MacBook Pro for only a couple of weeks, I've come to the conclusion that there are some pretty weird issues between the power manager, usb bus and airport (and from what I've read here, are pretty widespread issues). First, every time I charge the battery, my Logitech MX laser mouse stutters and jumps all over the screen (trackpad works smoothly though). If I turn off airport, the mouse works smoothly again. When the battery is done charging, the mouse will work smoothly again. Second, every now and then (when the mouse isn't connected) the trackpad will start to stutter and jump all over the screen. When this happens, I've noticed that the graphics card is running slowly as well (expose stutters). Both of these issues can then be remedied by one of two actions, either plug something into a usb port, or turn off airport. I am also suffering from the missing first letter issue, which also seems to go away by disabling airport... So, since disabling airport most of the time is not an option, anyone care to take a guess as to how long it will take Apple to come up with a fix to these issues?

    TM does not backup to a networked drive in the same way as a directly connected drive. A networked drive requires the creation of a .sparsebundle disc image file that holds the actual backed up files. So when you shift from direct to networked connection TM actually makes a different backup. This is unrelated to the actual type of port connection. So there's really nothing you can do to have TM use one backup for each type of connection used in your situation.

  • T430s Issues with Power Manager

    Just to note, I don't have the big issue with the DCC and FCC not matching up that seems to be plaguing many of the T430s users.  I do have a Panasonic battery, FYI.
    So I got my T430s late August and for the past few weeks, I've been noticing that I lose about 1% of battery a day even though it is plugged into AC.
    I also have a problem with the laptop not going into non-AC mode when I pull the adaptor out of the socket.  It remains on AC mode, which drains the battery more than it should be.  I have to physically go into the power manager and change it to a power saving mode for it to change down.  This doesnt happen all the time but it does happen quite frequently.  My default power setting is default "Power source optimized"
    My Power Manager firmware is 6.36 (I think this is the latest one)
    Anyone else having these issues? Any firmware upgrades that should fix this problem?

    'afternoon...
    Welcome to the community.
    Not sure if it will help out, but please check to be sure you also have the latest Power Management driver installed. You can find it in your driver matrix. I don't have the link immediately at hand or I would post it.

  • Compatibility issues between iMacs running CC Cs6 Premiere Projects.

    I have a 27" iMac at work, it has 3.4 ghz processor Intel Corei7, w 8gb 1333 mgz DDR3 ram, and a Radeon HD 6970m 2048 Graphics processor, it has OSX 10.8.3
    at home I have a 21" iMac, with a 2.7 ghz Intel Core i5, 16gb 1600 mgz DDR3 ram, Nvidia GEForce GT 640 w 512mb running OSX 10.8.5
    I want to work on same project in both locations. The 27" will not open a project started on the 21" and I have updated both Premiere's on the same day. Is this a hardware issue, or how the imac preferences are set up? I also have issues running Magic Bullet with Premiere on the 27" and no issue integrating it on the 21".
    Any help would be appreciated.

    My concern is going back and forth between the versions...  I read somewhere there are compatibility issues with Premiere....Can the user working in CC go back to premiere CS6? and vice versa?

  • Known backwards compatibility issues between Robohelp 9 and Robohelp 8?

    Hi Group,
    In addition to avoiding the tasks in the Review menu, does anyone know of any other backwards compatibility issues encountered while opening and using files generated in RoboHelp 9 from within Robohelp 8? Thanks, gail

    Welcome to the forum.
    Simply the fact that RoboHelp 8 will not open a project that has been run in RoboHelp 9. Sure you might well open a project by deleting the CPD and perhaps the XPJ and using the HHP, however I would not recommend that except in an emergency.
    What I am not clear on is how you link that to "avoiding the tasks in the Review menu." What has that got to do with the question?

    As my understanding there is no issue for Forms 4.5 and Reports 2.5 with R12.
    You can develop report with Report 6i can be deployed with R12.You cannot use Forms 4.5, Reports 2.5 or Developer (Forms/Reports) 6i with Oracle EBs R12 as it is not certified. The only supported version is Developer 10g

  • Compatibility issues between PS3.0 and Windows Vista

    Have PS3 for Windows XP. Have had it a while and it wouldn't load on my old computer because the harddrive didn't have enough space.  Now trying to load it on to HP Pavilion bought last spring.  When I tried to load it, I got the error window with: compatibility issues with this software.  Windows didn't find a solution.  Went to adobe.com and tried update for PS3.0 which I thought should work.  it said 3.0.1.  Won't work.  What am I missing?  Am I missing anything?  Will Adobe work as I want it to work?  As it's supposed to work?

    Well, it's not "supposed" to work in Vista. The earliest version of Elements that officially works in Vista is 5, with the special patch. However, some people have had success running earlier versions in XP compatibility mode.
