Any comments on battery backup

any comments on battery backup, size of backup, favorite brand?

What is your goal with battery backup? You can invest hundreds in a battery backup (UPS) system that will allow you to keep your computer running for an hour until the power turns back on, or you can invest a much smaller sum (~$100) to get a UPS system that will provide you with enough time to safely shut your system down in the event of a power failure. I chose the inexpensive solution by purchasing a 1000 VA UPS from my local discount warehouse store. I have been quite happy with it, although after about 4 years the lead acid battery wore out and required replacing.

  • Is there a log entry indicating the use of battery backup?

    I have a Late 2013 iMac, 27" i7 780m running Mavericks 10.9.4 - Is there an entry in any of the System Report logs that shows whether or not the computer had to make use of a UPC battery backup?
    I've experienced some of the same issues people have had with their system not waking from sleep, having to resort to using the power button to get things moving again. Today, however, we had a serious thunderstorm and when I got home the system was shut down (or possibly not wanting to wake from sleep - the iMacs have no glowing light like my old Mac Pro, so there's no way to tell if the thing is shut down, a "heavy sleeper", or what). I'm asking the above question because if the system ever does have to rely on the battery backup while I'm away I want a way to confirm the system is actually using the UPC and shutting down properly (via Power Management settings) and not simply getting knocked out by a power failure.
    It's somewhat unrelated, but the not-waking-from-sleep issue factors into this because that problem seems to be unrepeatable under any controlled circumstances. The support documents starts with disconnecting peripherals that might cause an issue, but the problem pops up so infrequently (weeks apart) there's no way to know if a disconnected USB hub is the culprit or a red herring. Today, for example, I'm left wondering if my issue was a power outage (the UPC should have taken care of a safe shutdown) or if I had an iMac not wanting to wake from sleep.

    Go to Settings>iCloud>Storage & Backup>Manage Storage.  Your backups are listed at the top, along with their sizes.  Note: this will only list your most current backup.  You may have your previous two backups available too but you cannot access any size information about them.

  • I don't have phone, but the TV says I need to replace battery backup for phone?!?!?!

    Hello,
    For three years, we've had Verizon Fios Internet and TV.  We've never had a phone.
    Today, the contraption Verizon plugged in the wall (sadly, I'm not really sure what it is, and had forgotten it existed until today as it's tucked behind some furniture) started beeping and the replace battery indicator light is on.  Furthermore, when I turn on TV, I am greeted with this message:
    My questions are:
    (1) If I don't have phone service, why would I even have a battery backup (much less need to replace it) to allow phone service during power outages?
    (2) Since I have only internet and TV, can I safely go without replacing this battery?
    (3) If the answer to #2 is yes, then how do I get the thing in the wall to stop beeping every 30 minutes?
    Thank you in advance to any responses.

    You can unplug the battery in your optical network terminal (ONT) and the message needing to replace the battery will go away.  Verizon customer service did confirm the battery is only for phone service when power is off.
    I was only able to find 3 links on the alarm / battery backup.  It looks like they never thought about people who did not want the phone feature and to silence the beeping with the battery removed?
    I don't know how frequently my unit beeps, but I don't normally hear it because it is in my garage.  I don't know if it has a pattern to when it beeps; but when I'm in the garage, I sometimes hear a single loud beep for about 1 second. 
    I imagine the battery must enable the laser to function when the power is off besides supply power to the copper phone lines in your house for a line powered phone.  I would assume then that if one had a UPS to power the computer and router and a good battery in the BBU; then one could have an internet when the power is off too?  Verizon user manuals don't mention this, so it might not work?

  • Best Battery Backup for iMac 27"?

    Just received my new iMac 27" i7.  I contacted Apple and they told me I don't really need a battery backup to protect the iMac but it's always a good idea.  So I am looking for an inexpensive backup to just protect the iMac and give me a few minutes to shutdown.  I have been reading about battery backups and from my understanding rating (va or watts) can be less than the iMac.  The only real difference is that the time to successfully shut down will be shorter.  Is this correct?  The 27" has a 340 watt power supply so I could get a 240 watt backup and be fine if I only wanted to shut down wilthout damage the iMac?
    Any suggestions on what to get?  It's almost impossible to make an informed decision because of specifications like "pure sine wave output", "dirty backup power" and "constant voltage source".  I am totally confused.  Do I really need one at all?
    Thank you

    Do you need to hook up the USB cable 
    You don't have to, but if you don't, when the battery runs out, your Mac will crash.
    If you connect the cable and set the preferences to shut it down after a certain period of time, or when there's a certain percentage of the battery left, etc., per the pink box in the link provided earlier, it will do a controlled powerdown. 
    and install the APC shut down software?
    No, do not install that.  It's been incompatible with Macs for several years. 
    Your Mac has the software already built-in.

  • Nokia 5800xm, very bad battery backup

    hi all,
    i have just bought Nokia 5800 XM, a week back. I am facing a very bad experience with this new phone since its giving a poor battery backup. The battery is not lasting even a day. I charge it fully in night and it starts getting down next day evening.
    I am not using any application, neither any surfing. My talktime in a day is around 3 hrs max and listen to music max 1 hr.
    Please suggest any workarounds, is this a generic problem all people are facing with this handset.
    Should i contact nokia for replacing it?  

    First, make sure you don't have any open applications in the background. Turn off bluetooth, Wi-Fi. Reduce the screen brightness to the minimum required for legibility. Reduce the level of haptic feedback. Make sure there is a good network coverage. Update the firmware to the latest version...
    If these are done, then take a look at the battery: use the phone until the battery goes dead, or until you see the Battery Low message a couple of times. Then, charge the batter to 100%, uninterrupted. Now, repeat it 2-3 times. After that, use the phone like you normally do. Charge it as and when you want.
    If you are comparing the performance with what is there in the spec-sheet, please be informed that what you see in the specs are the ideal values - under "standard test conditions". In practical life, you should expect considerable differences. 3 hours of calls and 1 hour of music does mean a good deal of strain on the battery. If the music is thru loudspeakers, it adds to it.
    Cheers,

  • IPhone Battery Backup on ios 7.0.4

    Hi
    I am facing a problem with my iPhone5 running on IOS 7.0.4, and it is the battery backup. Only Wifi was turned on.
    I have reduced screen brightness, turned off 3G and no location services is running and i dont know why, I hardly get 6 hours of Battery Backup.
    Is there any thing else i need to turn off.
    Is this only happening to me , or every one else having the same issue?
    Provide me some solution...

    hi
    they keep deleting my posts about that, but what helped me tremendously was simply switching off SIRI competely...
    My phone died within 4-5 hours (new, clean install, the third new hardware in a row)... and since I switched off SIRI it holds the battery for over 24 hours even if I use it a lot...
    told it to the Apple Store 'geniuses' today in Berlin, hopefully that info makes it into the next update.

  • Battery Backup light comes on for no apparent reason

    Every so often the light on the battery backup unit (BBU) that indicates the unit is using battery power comes on even though there was no power failure and there is AC power to the unit.  The first time this happened I called FIOS tech support and they indicated that if the light was on, the unit was operating off of battery power even if AC power was available, and that I would need to reset the unit.  They then took me through the procedure for resetting the unit:
    1) Open the case to the BBU.
    2) Unplug the battery.
    3) Unplug the AC power.
    4) Wait at least 3 minutes.
    5) Plug the battery back in.
    6) Plug in the AC power.
    This seems to do the trick and I assume it also resets the ONT.
    I have 2 questions:
    1) Why would the unit decide to operate off of battery power when there was AC power available and there had been no loss of AC power to begin with?
    2) Is it true that if the battery light is on the unit is operating off of battery power even in the presence of AC power?
    Any thoughts on these question would be appreciated.

  • I am experiencing low battery backup after upgrade to OS X Mavericks

    i am experiencing low battery backup after upgrade to OS X Mavericks

    Try these in order testing your system after each to see if it's back to normal:
    1. a. Resetting your Mac's PRAM and NVRAM
        b. Intel-based Macs: Resetting the System Management Controller (SMC)
    2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
         Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
         COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and
         after the chime press and hold down the OPTION key until the boot manager screen appears.
         Select the Recovery HD and click on the downward pointing arrow button.
    3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
         Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).
    4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).

  • Mountain Lion upgrade reduced battery backup

    After updating Mountain Lion my Macbook air battery backup reduce from 5 hours to 3 hours.
    Any suggestions?

    First, empty the Trash if you haven't already done so.
    Use a tool such as OmniDiskSweeper to explore your volume and find out what's taking up the space.
    Proceed further only if the problem hasn't been solved.
    ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To really see everything, you have to run it as root.
    Back up all data now if you haven't already done so. No matter what happens, you should be able to restore your system to the state it was in at the time of that backup.
    Launch the Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the page that opens.
    After installing ODS in the Applications folder, drag or copy — do not type — the following line into the Terminal window, then press return:
    sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
    You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.
    I don't recommend that you make a habit of this. Don't delete anything while running ODS as root. When you're done with it, quit it and also quit Terminal.

  • Poor battery backup

    Hi
    I recently got Mac Book Pro with Retina Display. Apple is claiming 7 hour battery backup but I am getting only approx 4.5 hours of battery backup. Any suggestions to increase the battery backup. I have tried disabling "Adjust Screen Brightness" & "Adjust keyboard lightness in low light".
    Appreciate your help.
    Thanks
    Ratnesh

    The Apple claims for battery life are based on very conservative test conditions that hardly reflect real life conditions.  Read their fine print very carefully.  I have found that 60%-70% of the advertised rate is an acceptable parameter.  Now if you use some really CPU intensive applications, the battery time will plummet.

  • My ipad2 gives 5-6 hours battery backup. But apple claims 10hours

    Do any other person noticed less battery backup.
    M facing this problem since very first day I bought ipad2.

    The battery life will depend on what you are using it for, e.g. watching videos will drain the battery quicker thatn reading ebooks, and what your settings are e.g. 3G on, wifi-on, location services on, maximise brightness. There are tips on this page for maximising battery life : www.apple.com/batteries/ipad.html

  • What to do for getting a good battery backup for E...

    I had brought the E6 after a convincing conversation at the Nokia Priority Partner shop and the executive there told me that E6 is a smartphone and also gives a good battery backup. Only on this condition I bought this new phone but to my misfortune this does not have a good battery backup. Everyday morning I need to charge my battery or the phone is dead. This is very much annoying as well as disappointing. I even suffered software issues with my E6. Thrice I needed to get its software reinstalled and even now having issues with the same. The priority centre only tells each time that you get the software reinstalled and your E6 will work fine. But I'm surprised that E6 only borrows my time to get it checked on the go.
    No doubt this phone is one of the best which Nokia has ever brought, but, still if it could help me sort this issue then I would rank E6 to be the best in its class.

    Which country did you buy your phone in?
    There are many posts dealing with this issue and steps to be taken to increase battery life.
    Some important ones are:
    1. Switch off 3G if you do not need it.
    2. Reduce the mail retrieval frequency if you have configured email accounts.
    3. Switch off automatic WiFi scanning.
    4. Reduce number of homescreens.
    5. Close any background application that you do not need.
    6. Switch to power saving mode when you do not actively use the phone for longer periods.
