Problem with power usage w/maintain lion

i had good battery life (6-7 hrs.) under lion and snow leopard, then i upgraded to mountain lion, now my battery life is 1h 15 min. I am now forced to switch back. BOO! I like the fixes to other thing but this stinks and is unbearable. back to lion 10.7.4 quick for me. ml 10.8.1 is more stable, but seem to use electricity like a mac pro.

Hi there:
Well my first and really only guess is that your refurbed power adapter is at fault here. If your old one wasn't doing this then I would say the battery is not at fault here. Maybe try calling Apple. Sounds pretty frustrating. Hope it ends up well.

  • Canon 860 Series (Pixma) Printer Problems with OSX 10.8 (Mountain Lion) – links to Canon Support Site with Drivers and Software with install tips

    After spending several hours sorting out Canon Pixma OSX problems here are my thoughts:
    Canon 860 Series (Pixma 868) Printer Problems with OSX 10.8 (Mountain Lion) – links to Canon Support Site with Drivers and Software with install tips
    Problem:
    - New imac and MacBook Pro 2012 (OSX 10.8.2) had a problem using Canon Pixma 868 printer on network and would not scan or print using Canon Pixma software (Pixma MP Navigator 2.1 & Photo Print), which has advanced scanning and photo printing functions. 
    - When I connected the canon printer to my imac, OSX 10.8.2 automatically downloaded and installed drivers for Canon 860 series printer. I could then add the new printer (select ‘apple menu’ / ‘system preferences’ / ‘print and scan’ / “+”) and printer would work while connected via USB but could not get to print or scan over network wifi. 
    - The original Canon 860 Series CD does not work with 10.8 and the manual / online instructions did not make sense (as based on CD install). 
    Solution:
    1) Install Canon Printer Drivers and Software (from official Canon site)
    Go to canon support site, review FAQ, then download and install following Pixma 860 Series software & drivers for OSX 10.8 (links see below). The version I downloaded is in brackets but check for updated version. Full instructions are below.
    Canon 860 Series Drivers & Software  for OSX 10.8 Mountain Lion:
    The base software and drivers needed for using Canon 860 Series on Mac OS X 10.8 (USB) are

    (Canon MX860 series CUPS Printer Driver Ver. 10.67.1.0 (03-Aug-2012))
    2 Scanner Driver
    (Canon MX860 series Scanner Driver Ver. 14.11.4a (03-Aug-2012))

    Canon Support (HK) – check your local site
    http://www.canon.com.hk/en/download/main/index.do
    Select Product and drivers from support site eg http://support-hk.canon-asia.com/
    1. Choose a product category
    Multifunctional Printers
    2. Choose a product series
      Pixma
    3. Choose a product model
      Pixma MX868
    4. Choose type of document
    Downloads or FAQ
    If you have problems installing the software under 10.8, see the FAQ on Canon site. You will need to allow software installs from “unidentified developers by using “Control” Key or by changing your system preferences)
    2) Check Canon Printer and Software Working while connected via USB
    Once you have downloaded and installed drivers and software and restarted computer, check that the printer and Canon Pixma software (Pixma MP Navigator 2.1 & Photo Print) are working via USB.  Open the Canon IJ Network Tool App (Applications / Canon Utilities /IJ Network Tool / Canon IJ Network Tool App) and make sure you can see the Canon MX 860 series (xx.xx.xx.xx.xx.xx) and that it shows the correct SSID Wifi settings (under the Canon IJ Network Tool App ‘Setup menu’).  This is normally done as part of the automatic install but worth double checking
    3) Add new network printer using ‘apple menu’ / ‘system preferences’ / ‘print and scan’ / “+”).
    After you have checked USB printing turn off printer, unplug the USB cable and shutdown the Canon IJ Network Tool App.
    Then turn the printer back on and wait 30s. Then add a new printer using ‘apple menu’ / ‘system preferences’ / ‘print and scan’ / “+”). Once you select “+” (add new printer), wait 10-30s for the Wifi Networked Canon MX 860 Series printer to appear in the new window eg Canon MX 860 series (xx.xx.xx.xx.xx.xx) (Kind: “Canon IJ Network”)
    DO NOT ADD THE MX 860 SERIES BONJOUR SCANNER (the Bonjour Scanner is the built-in software, is not needed and often appears first on the add printer list).  The Canon scanner can be accessed used through the MP Nav EX Ver. 2.1.3 software (which has much better functions)
    You will now have two Printer Canon MX860 (USB) and Canon MX860 (Wifi / Network). Set the Canon MX860 (Wifi / Network) as default and test print and scan
    If the Wifi Networked Canon MX 860 Series printer does not appear, check the printer and make sure that the printer can see the wifi network. On the printer select Menu / Settings / Device Settings / Lan Settings / WLAN Setting List.  It should say WLAN Active, identify the SSID and have an IP address
    If the printer can not see the Wifi Network, plug the USB cable back in, then open the Canon IJ Network Tool App (Applications / Canon Utilities /IJ Network Tool / Canon IJ Network Tool App). Make sure you can see the Canon MX 860 series (xx.xx.xx.xx.xx.xx) and that it has your SSID settings (under setup), if it has this info, restart the computer and the printer and try again

    Hi, thaks for response, meant to post as a discussion (not question), wanted to save others time if they get the same problem

  • Problems with connection to the Mountain Lion

    Someone is having problems with connection on Mac Mountain Lion? I did a clean install and the connection is unstable.

    Have you tried to reset your network settings ?
    What I would do is delete the connection, and then retry the set up of that connection.
    System Preferences>Network, select Wi-Fi on the left and then click on the 'minus' button

  • [5800xm] Problem with rSAP usage in Skoda nav-syst...

    Hello,
    like in the topic: I have a problem with rSAP usage in Skoda nav-system Columbus: it stays ON searching for the car nav-system & eats battery level (just being standby): within 24 hrs completely empty. With bluetooth turned on, without previously connecting to my Skoda nav-system, the phone can run for about 10 days standby.
    I tried every setting without improvement, I run the latest firmware/software on my 5800 XM.
    Only if I turn off manually the bluetooth subsystem (not just the nav-system connection, but completely turn off bluetooth), then the phone doesn't eat through my battery-level. I dont want that, because it's not neccessary (I have to turn it back on again later & forget to do that), sometimes I forget and find out people can't reach me coz my phone is battery-empty.
    Anyways, this situation is already since the beginning when I bought the phone from Nokia store. No improvement since.
    Please can anybody help out?
    Thnx
    Solved!
    Go to Solution.

    Well, since a few days we're testing the default setting from  aspergerguy  and now it seems the battery problem doesn't occur no more. Amazing how such a small change of unexpected / undocumented setting can give a device real purpose instead of almost uselessness.
    For clarity, again the problem: I am able to use the phone with the carkit-nav system, but after using (ergo: getting out of the car, into our home), the phone eats through the battery within 24hrs.
    This now no longer happens with   Wireless car kit   set as default.
    Thanks aspergerguy for your help!
    Less thanks Nokia for creating this problem in the first place.
    Regards,
    Quan

  • My HP Notepad 6730b has a problem with power

    Hi all,
    My HP Notepad 6730b has a problem with power. I can't power into the laptop. I have checked the power adapter and it works fine. No lights flash when i plug it into power. Can any one please help??

    IPad bought on May 29. This is the first attempt to use. I also bought the screen protector and apparently the problem started after I installed the shield and the battery charged, which was low.
    I followed the instructions, made ​​the recovery at iTunes, sync, but I could not turn on the Touch Screen. The clock remains stopped at 9AM. I will try an Apple store in Brazil to see what is happening and then notice what happened. Best regard and thanks for the help

  • Does anyone have problems with data usage with att and Iphone5?

    Hello, Does anyone have problems with data usage or non usage I should say with Iphone 5 and AT&T?

    After 4+ months of dealing with this data usage and battery drain problem that included 3 data captures of my wife's iMac, the trigger for us regarding the problems syncing with iCloud, and 5 hours of logs off my iPhone 6 to be analyzed by Apple engineers that included times my wife's computer was both on and off to demonstrate the difference in data usage and battery drain under those conditions, I can say with very reasonable certainty that the iOS 8.3 and corresponding Mac OS 10.10.3 update has solved the problem. 
    We have now been running for about 2 weeks and data usage with the iCloud Servers attempting to sync has dropped from a rate of 31 GBs to under 15 MBs per month.  Yes, you read it right.  We were burning 2000 times as much data doing absolutely nothing important on both of our phones, a 5s and a 6.  Just imagine what that does to battery life!  The 5s would last about 5 hours and the 6 was dead in less than 14.
    The distasteful aspect of this process was how the engineers were quietly fixing the problem at the same time sending messages to my contact person within Apple that were dismissive in nature in the face of indisputable unreasonable results. I must say, this experience with the multiple times the engineers' responses were inappropriate put a little tarnish on the old Apple shine of the ‘It just works’ mantra. This was my first experience in 34 years that caused me to stop recommending Apple products without reservations and with a disclaimer.
    Since the update solved the problem, then I can only conclude that there was a logic bug regarding the reaction within the process to the incoming data that was corrected.  There was noting short of logging out of iCloud that circumvented the problem for us, Gator5000e and probably many others noted on other threads.  I am not trying to imply that this is the cause of everyones battery use problem, but it is reasonable that it was a cause for many.

  • Weird problem with power shut down msi nforce 4 platinum

    recently i have flashed the latest bios 1.9 of msi nforce 4 u platinum, everything work fine untill yesterday.some stanges happened......
    my power doesnt have a on and off button on it ,every time i turn off the pc , i have to turn off the power button of a socket near by the pc.everytime it works fine, but yesterday when i turn on the power on button of that socket , the pc automatic start, i didint turn on the power button of pc, what a weird problem..   also when i  go into os , the system time also changed, although i can turn them back to correct one in bios and os, but when i turn the pc off , it changed again...   could any one help me out , what is teh real problem of my pc. some virus ?thanks a lot.
    weird problem with power shut down  msi nforce 4 platinum

    it seems the first question has been solved. cos today when i turn on pc, the oc set up is gone ,in bios, it back to the original set up.i cant save my oc setup, so it definitely a battery problem!!!!!!!!!!!
    i take the old battery t o a saler , there they massure it with voltmeter, it shows only 0.97v, but in bios 1.6 it shows 1.82v, so waht is the real meaning of that reading num in bios for battery?it cant be the real voltage of the battery. i buy a new one ,this one is maxcell 2032   hitachi, the old one is shi  t   panansonic 2032 .the new one shows 3.17v with voltmeter, then i come back , installed the  new battery , in bios this time it shows 2.3v in bios 1.6. so the reading num in bios for battery is definitely is not a real reading for your battery.
    i will keep my pc in 24/7 using , and i will look if the battery is sable or not , cos untilll now no one come out for a real explain for this  stupid battery problem of msi nofroce 4 platinum.i dont want change battery every 2 or 3month, what a real sick of this!!!!

  • Problem with different calendars under Mountain Lion

    I upgraded recently from Snow Leopard to Mountain Lion and experiencing an annoying problem with the calendars "On My Mac" (I am using a MacBook Pro from mid 2009). With iCal under Snow Leopard I had seven calendars - Meetings, Performances, Family, etc. with different colors. After the switch to Mountain Lion these categories aren't maintained properly. Four of them have been seemingly merged into two, so that for example an event can't be categorized as "Family" but gets shifted automatically to "Meetings" (both calendars stay checked in the editing panel, but only one "sticks"). So I have three  calendars I can use and a four I can't.
    If I try to add a new calendar it appears in the list, but no event can be assigned to it.
    Is there a limit to the number of calendars one can have?
    I don't use iCloud, so there is no issue there.
    I have one Google calendar (a work schedule I have subscribed to ) which also works with no problems.
    Any ideas?

    Same problem when reseted  the PRAM.
    I read some Chinese Web , Many people got the same problem after upgrade to mountain lion

  • Hanging problem with Adobe CS6 in Mountain Lion

    I recently upgraded my retina Macbook pro to Mountain Lion and was having some trouble with Adobe CS6 apps hanging on startup among other things (including iCal crashing on startup)
    I did a clean install of Mountain Lion and Manually rebuilt my applications folder so that Adobe MAster COllection was installed freshly on a clean install of ML.
    Now it is still sporadically hanging when I try to open Photoshop, Bridge or other Adobe apps. The only thing that seems to fix it is a restart which is inconvenient when you're in the middle of work.
    ANy ideas?

    Thanks for this. I had heard of the fonts problem some people have had. All my fonts were freshly installed by either the system or Adobe when I installed Master Collection. Following your advice, I just verified every font and the only problem that showed up (as you had predicted) was a minor duplication which I corrected. So, it seems unlikely to be the fonts.
    As for your other point, I have been using Final Cut Pro X and that has worked fine. The only other app that has given me trouble has been Calendar which seems to get strangely stuck sometimes while it is updating. Makes me wonder if there's something going on with the network I'm using. 
    One thing I hadn't thought of was that it could be a problem with gfx card switcher. This seems unlikely but I'll try disabling it and see if that helps.
    Weirdly, today when I had this issue, Photoshop loaded up ok but then hung when I tried to load any file into it. Bridge wouldn't start at all. I didn't try the others. Yesterday I was having problems with Illustrator.
    Anyway, I see what you mean about it not being a widespread problem - which is why I started this thread. It seems no one else is having any issues. If anyone else knows what I should look for in my configuration please let me know.

  • Problems with officejet pro 8100 and Lion?

    I just bought a new HP Officejet Pro 8100 Wireless and I have not been able to get it to work correctly.  It's hooked up and all the software seems to work but it prints very, very slowly.  It takes about 2 minutes to print a color page.  Is there some known problem with OJPRO8100s and Macs with OS X Lion on them?  I downloaded v12.14.0 of the printer package from HP, uninstalled what came with the printer, and installed the latest and greatest.  Didn't make a bit of difference.

  • Problem with memory usage and CPU usage

    Hello,
    i have a problem with the memory usage and cpu usage in my project!
    My application must run for more than 24 hrs. The problem is that the longer it runs the bigger is the memory and cpu usage!
    It starts with ~15% CPU usage and ~70 MBytes memory usage. After ~ 24hrs the CPU usage is ~60% and the memory usage is ~170 MBytes!
    After  3 days the CPU usage is almost about 70% and the memory usage is about 360 MBytes!
    What can I do to reduce this huge recource usage?
    Thank you!

    Hi Pahe,
       I think the issue is memory usage, since CPU usage can increase due to greater memory requirements.
       Anyway, it's difficult to debug without seeing your code, can you post it (possibly for LV 7.1 compatibility)?  Or just post a JPEG of the piece of code that can give problems...
       I guess you're appending data to an array instead of replace data elements, but I can't be sure...
       Have a nice day!

  • Problem with Clip Usage and merged clips in CS6

    The 'Clip Usage' drop-down menus don't seem to work in Premiere CS6 for merged clips. The info bar at the top of the project window correctly lists the number of times the viedo and audio from the clip has been used, and the downward-pointing arrow appears, but when you click on it... nothing happens. Same's true of the 'Video Usage' column in the main body of the project window. Non-merged clips work just fine.
    Anyone know if this is just a problem with my project, or if it's a bug in Premiere? Had a lot of trouble with merged clips in CS5.5, and was hoping they'd be solved by CS6 - I've been using Creative Suite for a long time, and the lack of good merged clips support was always one of the challenges in persuading other indie editors to switch over from FCP...
    Thanks!

    ...and the lack of good merged clips support was always one of the challenges in persuading other indie editors to switch over from FCP...
    I guess they just have to weigh that up against the lack of support they got from Apple for FCP in its entirety.

  • Is anyone else having problems with Office for Mac and Lion?

    Since installing Lion 10.7.1 on a macbook pro 2.53 Ghz 4GB 1067 MHz DDR3 I have had no end of problems. Both Excel and Word hang, crash and saving an Excel file is a pain. A 12mb spread sheet just took 4 minutes to save! I have MS Office for Mac 2011 version 14.1.3.
    Another problem that may not be related to Office is that opening Finder is so slow and most of the time it takes a minute to display folders in Desktop or Documents.
    Any suggestions would be welcome .. I regret installing Lion .. I had no problems with Snow Leopard!

  • Mouse problems with Illustrator CS6 and Mountain Lion

    The mouse in Illustrator selects and deselects as it moves over buttons and cells:
    1. In Graph data the cells the mouse passes over go dark grey if not already selected, then deselect if they are selected. This makes it very difficult to use the data cells.
    2. In Layers window, where I may have 100s of layers, I want to hide one layer or more which are not necessarily adjacent to each other. Illustrator hides all of the layers it passes. It is very difficult to click and unclick the show/hide button (and also the lock button). Ditto with show or unlock toggle layer. I had to start up in Lion in which Illustrator does not have this problem in order to get a job finished in time.
    Seems there needs to be a fix for Illustrator to work properly in Mountain Lion.
    Has anyone found such a fix?

    No I don't have Right-Zoom (don't know what it is), but I have the same problem with Apple's Track Pad, which I don't use much and I only use the inbuilt software.
    I use Kensington Slim Blade and before that LogiTech's marble mouse and both need their software to work properly.
    All of them work fine in Lion and earlier. Could it be that Adobe has overlooked some new aspect that’s in Mountain Lion which, in my case, needs to be fixed for Illustrator?

  • Problems with typing in mac os lion

    hello,
    just two days ago I had some problems with my MacBook Pro running with Lion, I just went to update my mac os 10.7.3 to 10.7.4 and suddenly it failed to instal
    just then I was told to restart my computer. Ater I restarted the computer there was a huge problem, I had a Kernel Panic issues and I realized that my mac OS had crashed. So I clean install my mac using my recovery disk that was given in the box by purchase.
    after re-installing I got this annoying typing problem (sorry for sharing a Youtube URL to show you exactly how it goes)
    http://www.youtube.com/watch?v=LVCwZD3ZEVU
    I have tried to turn of the auto correct feature on Text & Languages in system prefrences but it doesnt fix anything.
    maybe you have some great solution to fix my problems? thanks before..

    If it happens in a new user you may be able to repair this with the 10.5.4 Combo Update This is a fuller install, as opposed to an incremental "delta" update so it should overwrite any files that are damaged or missing. It does not matter if you have applied it before.
    Remember to Verify Disk before update and repair permissions after update from /Applications/Utilities/Disk Utility.
