Dumb question about cycling a battery. Sorry!

I just received by new mac book pro replacement battery today and I have some questions regarding it. First of all, my original battery lasted 2 yrs, 2 mos. I purchased another apple battery for my 15 inch mac book pro (computer originally purch. Aug. 2007). I've seen on these boards that I'm supposed to "cycle" the battery once a week to get the maximum life out of it. I think a cycle means using the battery until it's power is used up and then charge up to 100% again. Is that right? Anyway, my question is, "What is the proper care for this new battery? Does it damage it to have it plugged in when it is fully charged? Or should I always keep it unplugged and use the battery until it runs out and then charge it again? And what does it mean to cycle it once a week, if I'm already using the battery and recharging it when needed?" Sorry if these are dumb questions. I'm not really computer savvy! Thanks.

You should use the battery for a while every day but not drain it right down, before re-connecting the power and re-charging it to 95%+ this is not a complete cycle but partial/normal cycling.
_Every couple of months_ you should re-calibrate the battery which means you keep using it until it goes into emergency sleep itself (you will see a warning then 5 minutes later it will go off by itself) and then _leave it in this state for at least 5 hours_ before you re-connect the power supply and fully charge it (without unplugging) - this is a proper re-calibration.

  • Question about using new battery in old Powerbook

    I have a pre-intel Powerbook G4, and the battery is pretty much toast (lasts about 15 minutes now). I have ordered a new battery for it, and I have this question about using it:
    Am I smarter to keep the new strong battery out of the PB most days (as I usually work with it plugged in at home) and just pop it in when I know I will be out surfing on batteries? Or is it just as good living in my laptop 24/7 and only occasionally being called upon to do its job?
    Current bad Battery Information below:
    Battery Installed: Yes
    First low level warning: No
    Full Charge Capacity (mAh): 1144
    Remaining Capacity (mAh): 1115
    Amperage (mA): 0
    Voltage (mV): 12387
    Cycle Count: 281
    thanks folks, Shereen

    Hi, Shereen. Every Powerbook battery wants to be used — drained and then recharged — at least every couple of weeks. If you've always used your Powerbook on AC power nearly all the time, and not followed that pattern of discharging and recharging the battery every week or two, it's possible that your use habits have shortened the lifespan and prematurely diminished the capacity of your old battery. Of course it's also possible that your battery is merely old, as a battery's capacity also diminishes with age regardless of how it's used. You didn't say how old the battery is in years, so this may or may not be an issue. I mention it only because it can be an issue.
    For general information on handling a battery for the longest possible lifespan, see this article. My advice on the basis of that article and long experience reading these forums is that it would be OK to do as you propose, but I doubt that you'd derive any significant benefit from it. You would still want to be sure of putting the new battery through a charge/discharge cycle every week or two, even if you didn't have a reason to use the Powerbook away from home or your desk, because sitting unused outside the computer is just as bad for a battery as sitting unused inside it. And you should never remove the battery from your computer when it's completely or almost completely discharged and let it sit that way any longer than a day or two.

  • A dumb question about wifi...

    I'm not as 'literate' as some are when it comes to computer technology...but here is the question...If I walk into a place that has wifi and my iphone is set with wifi ON, how will I know if there is a charge for using the wifi? Will my iphone automatically kick into the wifi or will there appear an invitation to pay a fee to connect...and how do you pay and do you have to have a password and if so, how do you get that? I know....dumb question...Thanks.

    Not a dumb question at all.
    First of all, set your iPhone up like this:
    1) Go to Settings on the main screen (looks like gears)
    2) Click on "Wi-Fi" (second option from the top)
    3) At the bottom of this page (Which should say "Wi-Fi Networks" at the top) turn "Ask to Join Networks" to the "ON" position.
    Now when you walk into a place that has Wi-Fi, your iPhone will display a little window that asks you whether you want to join the network or not.
    In some places, you may even see a list of more than one Wi-Fi network to join. This is quite common in New York City. The reason is because so many people have Wi-Fi in there apartments, and they all live so close together, that sometime your iPhone can detect multiple networks. The coffee shop near my apartment has their own network, but I can also connect to the Wi-Fi network in my apartment because I only live about 50 feet away.
    Anyway, when you see the list of Networks to join, you may notice a little padlock symbol next to some of them. This means these are closed networks that require a password to connect to. (My network is "Closed", ie requires a password so that everyone in the coffee shop next door doesn't use my internet).
    Networks that DO NOT have the little lock symbol are "Open" which means you can join them without a password. But there is a catch... A lot of coffee shops have open networks, but as soon as you try to browse the web, they redirect your browser to their own page, no matter what web address you enter. Basically, they are letting you connect to their network without a password, but not letting you browse the internet without giving them some money.
    So (as the previous poster said) the page that the coffee shops redirects you to, usually has instructions, and of course a place to put in a credit card. Once you do all that, then you can browse the internet without getting redirected to their little payment page. Its sort of confusing because you don't need a password to connect to their "open" network, but you do need one to browse any web pages. How you get the password differs from coffee shop to coffee shop, but usually they give it to you right inside your web browser once you give them your credit card number.
    T-Mobile provides wireless for Starbucks (at least in a lot of places they do). So once you have an account with t-mobile, you can use it in any starbucks or "T-mobile hotspot"
    Now this all sounds kind of complicated, but more and more these days, you can just walk into a place, find an open network (one without a lock next to it) and start browsing without being redirected or dealing with credit cards. Basically these places are providing free internet to try to attract customers.
    Good luck
    P.S. Wi-Fi eats up battery life. If you aren't going to be using it to browse web pages, you can go into settings, then Wi-Fi, and turn Wi-Fi off. This will save you battery life, but you have to remember to turn it back on. Even without Wi-Fi on, you can still browse the internet if you see a little "E" at the top of your screen. The E stands for the AT&Ts Edge network, which isn't as fast as Wi-Fi, but covers pretty much everywhere that your phone can get a signal.

  • Maybe a dumb question, about which power connectors to use, but....

    This may sound like an incredibly dumb question, but here goes anyway....
    I upgraded my system a few weeks ago, and will be slapping in a new ATI X850 Pro AGP card in a few days.  My current graphics card is a p.o.s. Radeon 9550, so it doesn't have its own power connector or even a fan.  My PSU is a dual-rail Antec model, and I'm wondering if it should matter any about how many or which devices I have connected to each power cable set.  My psu came with cables to attach, only 2 of the 4 though are the 4-pin molex - the other 2 are pci-e power connectors I believe.  Should it make a difference which or how many devices I connect to each cable?  For ease of plugging in, I believe my DVDRW and CDRom are using 1 cable, and my ide drive and floppy are using the other cable. Also, I have a pci fan and a case fan running off 1 or the other.  I'm likely to jump the power cable for the video card off the one the hard drive is using, unless someone has some suggestion to offer to the contrary.
    If it makes a difference, can anyone recommend how they would have them connect?
    My list of devices to plug in would be:
    1)IDE HDD
    2)Floppy
    3)CDRom
    4)DVDRW
    5)Case Fan
    6)PCI Fan
    7)Video Card
    Thanks for any thoughts!  SAB - you seem to be the man on builds.....any ideas? 

    Well, I put the new card in and connected it on a cable with the optical drives.  Also, I had unwittingly connected my cdrom on the same ide channel as my hdd    , so I changed that so both optical drives are on the secondary ide.
    So far, so good.  3dMark03 jumped up from 3300 with an overclocked Radeon 9550 to 10570 with the stock Radeon 850 Pro 
    I wish I could find some local source to purchase additional molex cords for my Antec SmartPower 2.0 psu, though - I've got 2 more 'outlets' just sitting there on the psu doing nothing, because the other cables are for pci-e, and I'm not using pci-e......  If I could buy some additional molex cables to plug in like the ones that came with it, I could have the vid card on its own cable....

  • Dumb Question about multiple BSSIDs

    This is probably a dumb question, but enquiring minds want to know...
    When using Yosemite's built-in Wireless Diagnostics scan I see many unique WiFi BSSIDs (MAC addresses) associated with my Time Capsule: 5 for my Guest Network and 6 for my "main" network. I see that not all have the same 802.11 protocol, but not all have unique 802.11 protocols. Also I see my "main" network is the 802.11ac network.
    So my questions are:
    - Why are there so many different BSSIDs and how should I interpret them?
    - Which of these BSSIDs are "relevant" that I should pay attention to?
    Thanks,
    Kevin

    Why are there so many different BSSIDs and how should I interpret them?
    The 5 GHz band on the main network is one unique BSSID
    The 2.4 GHz band on the main network is one unique BSSID
    If you have the Guest Network setup......
    The 5 GHz band on the guest network is one unique BSSID
    The 2.4 GHz band on the guest network is one unique BSSID
    If you have multiple AirPort routers, repeat the information above for each router.
    Which of these BSSIDs are "relevant" that I should pay attention to?
    Personally, I pay no attention to this, but some users place great importance on this.
    The BSSID tells you which AirPort.....if you have multiple AirPorts....and which band....2.4 GHz or 5 GHz.....that you are connected to at the current time....as well as whether you are connected to the "main" network, or the "guest" network.....if you have enabled the guest function.

  • Dumb question about browser dectection

    I have a web application that looks awesome in IE but in Firefox it looks clunky and blocky. What I need to perform is a validation to see what browser the client is using. I have done this before on simple html pages javascript browser sniffing. Well it seems that I can't for the life of me to be able to get this working in Creator.
    My web project is a Sun Creator Web application. My OS is Windows
    Does anyone have any idea or references that you could supply to me?
    The following code works in an html environment but in a jsp I cant get the different style sheets to work.
    document.write("<link id="link1" rel="stylesheet" type="text/css" href="/WebDemoExtractor/resources/introductionFireFox.css" /> ");
    U jave tried many variations of the following
    document.write("<ui:link binding='#{introduction.link2}' id='link2' url='/resources/introductionFireFox.css'/>")
    I have tried performing many variations with the the above and I have had no success.
    Is it even possible to perform this function??
    Thank you

    I think you mean how is it possible to view YouTube videos in Safari on iPad, right?
    Basically, YouTube senses the browser you're using. Because Safari on iPad doesn't support Flash, YouTube delivers the movie in a format the iPad can play (like H.264, as a previous post mentioned). This happens with YouTube videos embedded on other web sites, too.
    I hope this helps.
    I was in an Apple Store a few days ago, and a teenage kid really wanted an iPad. His dad said, "but it doesn't play flash, so you won't get to see YouTube videos that you love." Kid said, something expletive deleted.
    The son then picked up the iPad, and he clicked on the YouTube icon. Walked out of the store with it. Sales guy and I laughed. Made my day.

  • Dumb question about user_sdo_geom_metadata DIMINFO entries

    I'm sure that this is a dumb question!
    I create a new entry in user_sdo_geom_metadata as follows...
    INSERT INTO USER_SDO_GEOM_METADATA
    VALUES ( 'PR_A', 'GEOM',
    MDSYS.SDO_DIM_ARRAY(
    MDSYS.SDO_DIM_ELEMENT('X',190000.0,640000.0, 0.05),
    MDSYS.SDO_DIM_ELEMENT('Y',120000.0,680000.0, 0.05)
    NULL );
    But when I select the DIMINFO from the table...
    SQL> select diminfo from user_sdo_geom_metadata a where table_name = 'PR_A';
    DIMINFO(SDO_DIMNAME, SDO_LB, SDO_UB, SDO_TOLERANCE)
    SDO_DIM_ARRAY(SDO_DIM_ELEMENT('X', 190000, 640000, 0), SDO_DIM_ELEMENT('Y', 1200
    00, 680000, 0))
    The sdo_dim_element and sdo_tolerance
    elements show no decimal places.
    Is this because I have not set some
    display number format option in SQLPLUS
    or for some other reason?
    regards
    Simon

    Simon,
    If you are using an old sqlplus client
    (815) then you won't be able to see the decimal places in the diminfo object.
    But if you hace a newer (816/817) sqlplus
    client you should be able to see the decimal places.
    If you are not seeing them in these clients
    then there might be some format paramter set
    to show numbers without decimals.
    You can do a
    show numformat
    in sqlplus to see if there is any format set for that paramter.

  • A very dumb question about sharing preview in an iPad

    Hi, folks
    I have to share some content I have made in some iPad devices. I am taking about a dozen of people, some of whom I don't even know.
    To test all this, I have reloaded in Folio Builder the content with our shared user account (ie: not mine) and now I want to test this sharing with myself, to see that in my own account and my own iPad.
    However, I see that this seems not to be possible. As fas as I have been reading posts here and there, each user has to start session with that shared account and then download the folio. Afterwards, they can restart with their own account and still see the folio, as it has been downloaded to their devices...
    Is that right? I mean: is there no other way but sharing the account and password with every individual likely involved? That gives me the creeps, to be honest.
    Thanking you in advance for all your patience
    Gustavo (Posting from Madrid).

    Yes, Bob I thought that was the way
    But I am a bit dumb-stuck in this. The user... let's say [email protected] has shared it and I have received his e-mail in my iPad. I have my account, let's say [email protected]
    How do I see / download it in the iPad?
    I must be a bit overworked to see it, sorry if so.

  • Dumb question about automation, but I'm stuck

    The first time you view automation, it asks if you want to view it globally or just that track. I selected just the track, now I need it globally. I can't figure out how to make the automation visible on more than the one track.
    Sorry for the lame question, but I'm stuck.

    I figured how to view the automation track by track, but there doesn't seem to be a total global fix.

  • Equium M50-164: Question about Fan usage & battery timer

    Hi !!
    Just got hold of my equium m50-164 laptop today and I wanted to clarify a few issues
    firstly,
    I flashed my bios with the latest version and upon the reboot the fan kicked in at full power and didn't turn off until i put the laptop into standby mode, this seemed to of rectified the problem but the fan seems to be kicking in a lot more than compared to before, luckily the fan isn't kicking into 100% speed but more like 15% - 20% every 30 secs or a minute then goes into silent mode, the fan hasn't hit 100% unless i do a reboot :),
    I know the fan will speed faster based on the cpu usage etc (thermal) but is this normal? I spoke to support and they wanted me to have an instant replacement but I said I would wait a few days to see if it would calm down :)
    and finally looking at the power meter and other software tools there seems to be no battery calibration, with previous laptops i noticed that numerical calculations are made based on battery usage and time left [i.e a timer] but with this laptop i kind find a timer - i would of thought tha every laptop has this facility nowadays !
    any advice would be helpful
    cheers
    Ephid0r UK

    Hi
    Please dont be mad on me but I really dont understood why your first step is BIOS update. The unit is delivered with actual BIOS and it is really not necessary to make it before you notice some problems. I just hope that you have enough experience with it because I have read a few postings on this forum about BIOS damage while BIOS update and to make it good again costs a lot of money.
    Your BIOS is updated and there are new values that should be used by Power saver utility (responsible for cooling fan monitoring). I recommend you to remove preinstalled power saver, restart the unit and install it again. I hope that the result will be better.
    Battery calibration I dont know what you want exactly but the battery usage can be control by power saver tool. On the task bar there is symbol for power saver and if you move the mouse pointer on it the battery capacity and left time will be shown.

  • I may have a relativly dumb question about the newer iTunes

    ok, I got a video iPod for my birthday, which was in the first week of august, and I put iTunes on my comp, but I haven't updated iTunes since because I have been reading there were so many bugs with the iTunes they released. Then I see they came out with a newer version, but I haven't downloaded it yet because I was afraid about the problems and bugs. My friend told me that apple fixed the problems, but I read a thing or two here about people having trouble with it.
    So I guess the question I'm building up to is, should I still be on the catious side and not download the newer iTunes, or is the newer iTunes ok?
    Me being computer illiterate, I'm not too sure what my comps insides are running other than Windows XP home edition

    Downloading videos on 7.0.2 hasn't worked as well as everyone had hoped. I still can't get mine to work, but i do know a few people who haven't had trouble with the newer itunes.

  • A dumb question about DVD Capacity.

    I want to create as high as quality DVD as possible from my iMove (5.02) project using iDVD (5.01). I've started off using DVD+R disks and I'm now considering using Dual Layer DVD's.
    The actual iMovie file size of my project is 12Gig at about 60 minutes. It's the same size when I SHARE as a full quality QT file. However when I create an iDVD Project from either the QT file or directly out of iMovie, my DVD Capacity reading is approx. 2.1 of 8Gig.
    Now my question is this: What exactly am I reading here? I was under the impression that the DVD Capacity indicated the size of the movie. Obviously a 12Gig movie isn't going to fit onto a DVD, so I assumed that this reading related to the compressed size, but am I wrong? I can't understand why a 12Gig movie would need to be compressed so much. If this is the compressed size, then how can I get iDVD to not compress it so much? I've tried using Best Performance as the encoded setting, but would expect something up in the 6-7Gig range.
    If I use a dual layer disk, am I only going to be writing a 2Gig file to it?

    Thanks.
    But two questions.
    My iDVD Capacity status bar reads this file as 2 of 8 Gig. Is it telling me that my imported iMovie will be compressed down to 2Gig, if so then why is it compressing the file down so much, OR if not what exactly is this information telling me? If I should expect a reasonable good compression from a 12Gig movie down to say 6 or 7Gig why isn’t it shown in the iDVD Capacity status bar?
    Also, at what point does iDVD work out the compression? I don’t usually insert a blank DVD in until I go to burn the project and iDVD requests one, up until that point how does it know what size disk I’m using 4Gig Single or 8Gig Dual Layer.

  • SUPER SIMPLE DUMB Question about hard-wired desktop mac and wifi for iPhone

    Sorry if this has been already answered a million times. I have a desktop mac with a cable modem ethernet internet connection. I want to leave this hard-wired and setup a wifi network for a laptop or iPhone. What's the cheapest easiest way to do this?? I've never done anything wireless before.

    Could I just somehow split the feed from the the cable modem or ethernet cable and route part of it into an AirPort express??
    Unfortunately, no. This would create "confusion" for the modem as it is only expecting a single device to be connected to it. To be able to support both wired & wireless clients, you would need an Internet router with a built-in Ethernet switch, like the AirPort Extreme Base Station. If cost is an issue, you do NOT have to use an Apple router. There are a number of other vendors, like Belkin, D-Link, Linksys, & Netgear, to name a few, that offer similar models.
