T61 Changing battery while on AC wall power

Newbie Needs Advice: This T61 is my first Laptop and I am still learning:
(1) While plugged into my AC wall power adapter and the computer running programs, can I take the battery in or out?
(2) Vice Versa - while running on the battery and the computer running programs, can I plug in or disconnet the AC wall power adapter?
Thanks!

From Online Help (Blue Button). I think that's a fairly authoritive source.
Before you start, turn off the computer, or enter hibernation mode.
Close the computer display. Note: If you are using a PC Card, the computer may not be able to enter hibernation mode. If this happens, turn off the computer.
Disconnect the ac adapter and all cables from the computer.
Turn the computer over. Unlock the battery latch by sliding to the left.
Holding the latch in the unlocked position, remove the battery.
Install a fully charged battery.
Slide the battery latch to the locked position.  
Turn the computer over again. Connect the ac adapter and the cables to the computer.

    Has anyone had this issue or know of a fix?
    Thanks

    Try this
    Restart iPhone: Hold down the Sleep/Wake button and the home button together until the apple logo appears (ignore the ON/OFF slider) then let both buttons go and wait for phone to restart (no data will be lost).
    Using the phone while charging doesn't create a problem.. I do it all the time

    Welcome to the Apple community.
    Did you follow the following instructions exactly:
    Remove ALL cables from Apple TV. (if you don't you will not see Apple TV in the iTunes Source list)
    Connect the micro USB cable to the Apple TV and to your computer.
    Reconnect the power cable (only for Apple TV 3)
    Open iTunes.
    Select your Apple TV in the Source list, and then click Restore.

  • Consuming battery while on Power Adapter

    I have a MBA bought 1 year ago, and lately I have noticed that the battery is not charging and it is consuming battery while having it on the power adapter. When netflixing, it is having the status: battery not charging and power source: Power Adapter, however, it is consuming my battery. Anyone experiencing this issue as well?

    remcodebtje
    however, it is consuming my battery.
    If you are on charge and using your Air, and the battery charge is steadily dropping, and there is either red or no green charge indicator on the magsafe,   this is not normal.
    Make an appt. for a visit with your local Apple store.
    It will only take a few mins to connect a charger and verify a blown / bad charging block board and likely blown capacitor
    which would be causing non-charging or preventing max-charge state when on power with your Air.

  • Advisable to take out battery while on AC Power?

    Is it better to take out the battery while working for a long period of time via AC power?
    I am worrying of overcharging the battery.

    Although the battery will not overcharge, and yes, the battery acts like a UPS, but that does not mean that
    Apple is right about leaving the battery in all the
    time.
    All battery types (Lithium-Ion in our MacBook) degrade with time. Heat makes it worse. Leaving the battery 100% charged
    makes it worse. See http://www.batteryuniversity.com/parttwo-34.htm
    I wish Apple provided a battery charge management tool like that which comes with the Thinkpad. It allows you to select the default charge level to leave the battery at, and has a built-in option to execute the charge down/recharge operation automatically. Its the only
    tool I'm aware of which is designed for folks who use their laptops as desktops mostly.

  • Apple TV changed battery screen shows setting  time etc now it will not start

    I had to change battery in remote (2nd gen apple TV) now it starts setting time etc screen is blank. I swithced it off waited 30 secs, no luck!!!!
    I cannot go to menu as it does not allow me. Has anyone got any suggestions??

    Here's what finally worked for me with Apple TV 3rd generation. Out of the box, when setup with wi-fi, it breezed through without any issue. As soon as I powered down and connected it to another tv (same wi-fi network), it got stuck at setting date/time. The remote would help in getting out of it, but the home would only have "Computers" and "Settings" and pretty much useless except for AirPlay. Here's what I did to resolve this:
    1. On your main router, temporarily disable the firewall or set it to the lowest setting allowable (a reboot of the router maybe required).
    2. Restart apple tv via the "restart" option in the "General" option in the main settings menu.
    3. It should breeze through and not show the "Setting date/time" screen.
    4. Once it loads up properly, turn on your fire wall as before  (a reboot of the router maybe required).
    I think it worked for me out of the box, but auto-update to the latest software introduced this bug. So, everytime apple tv tries to synch with the time server, this issue will come back. To disable this, I turned off the "auto time synch" option in Settings -> General.
    I am fairly confident that I'd be able to use steps 1 through 4 anytime this recurs. Possible scenarios causing recurrence of this issue:
    1. Unplugging the power to apple tv or power failures.
    2. OS updates.
    3. Restoring apple tv using "Restore" or via micro-usb and iTunes to the lastest OS.
    Hope this helps. Please post if this works for you.

  • IPhone 4S only powers up, works, when connected to wall power

    Brand new iPhone 4S, arrived two days ago on the model's launch day.  Few glitches, expected w/ new phone, not a big deal, worked through them, initially did restore-type installation to transfer all info from old AT&T iPhone 3GS, still w/ AT&T.  It was working fine.
    Then, connected to wall charger last night.  This morning, before disconnected from wall charger, charge showed 87%, then disconnected and screen went black.
    Phone did not, and does not, respond when unconnected.
    Connected iPhone to MacBook Pro, result is same as when unconnected, no response.
    However, when iPhone connects to wallpower, it works fine.  Powers up, all functions seem to be normal, but noted that charge now shows only 84% and it's not going up, as it should.
    I have been studying these boards today before typing this post.  Have tried the reset procedure (hold down sleep/wake + home buttons simultaneously for 30+ seconds) when iPhone is unconnected and when iPhone is connected to computer, still unresponsive.  Also tried reset procedure when connected to wall power, it eventually goes into reset mode and it eventually got to the point that it said connect to iTunes, but when I disconnect from wall power and connect to computer, it is again unresponsive.  After doing that, connected to wall power, and it powers up normally.
    With iTunes open and running, the iPhone does not appear therein when connected.  Left iPhone connected to computer all morning, no changes in nonresponsiveness.  Before last night, this was not a problem.
    Before I even starting using this iPhone, I'd put it in a nice, new OtterBox case.  It has not been dropped or mishandled or gotten wet.
    My conclusion is that there's a hardware problem that I cannot fix, and even if I had a clue what to do, I'd probably void the warranty.
    Looking for suggestions as to what to do short of calling AppleCare.  Any help will be most appreciated.

    Called AppleCare this morning, confirmed that this is a hardware problem. Getting replacement.

  • Nano won't play using the battery, but ok on external power.  Got washed in the washing machine.

    I washed my nano with my jeans in the washing machine.  It still works when I use external power, but not on the battery.  I've charaged it, but it doesn't hold the charge.   Sugggestions?

    The battery is dead, permanantly pretty much.
    I had this happen to an old nano, 2nd gen or 3rd i forgot which it was.
    Anyway i went in a lake with it, after that it would no longer work on the battery, but would with external power.
    I spent a good while looking for a solution but couldn't find a fix or any suggestions other than replacing the ipod battery, or the ipod itself.
    I did keep it though and just kept it on a ipod player speaker device though. Maybe now theres a trick to fix it or something but i highly doubt it.

  • How to change battery charge settings in Windows 8

    On my previous Thinkpads I could change the battery charging settings in Lenovo Power Manager. (things like minimum charging threshold, etc). Now in Windows 8 Lenovo seems to have abandonded the Power Manager, but there is still a power manager driver. Is it still possable to change the battery charging settings?

  • My S5 IS Powershot gives "change battery" message

    My camera was working well until recently. Now, when in shooting mode, I get a message "change battery" or "charge battery" even though I have tried several sets of fully charged batteries properly inserted. In viewing mode I can see olf photos without trouble but in shooting mode I get the message.

     I happen to know a lot about the S5 iS model. Since you tried several good batteries the problem is after the battery.
    Inspect the inside of the battery compartment for dirt or corrosion on the contacts inside.A product called Deoxit 5 is good for cleaning that and wont hurt the plastics.
    If you have the AC adapter try using the camera with that, no battery, that could narrow it down as to where the problem is.
    Remove the battery and the date button battery close up the battery compartment and move the power levery to on-hold it there for at least 30 seconds.
    In the end if it is not an easy, no service needed fix the cost of a repair will most likely not be worth the value of the camera on eBay for instance.

  • How to test T61 backup battery?

    Hello,
    am taking apart a T61 for cleaning, OS reload etc and am thinking of testing the backup battery while I am in the maintenance mode. The maintenance manual indicates to remove the battery and measure the voltage, but doesn't indicate how to do this, I have a multimeter but have no idea how to test this particular part.
    Any suggestions welcome.
    Thanks!

    Go to Solution.

    it's a simple DC battery with two wires, you just check the voltage across them, but I'd recommend you remove any bios passwords you may have set first. 
    Also, these batteries don't often go bad, so you can simply remove the main battery and unplug the AC for a few hours and if the clock remains set, the cmos battery is working.

  • Using battery while charging

    Pretty much the headline.
    When im using my Macbook Pro 15" late 2011, for gaming, its using battery while the charger is pluged in.

    If your charger is working right, it is NOT using your battery while gaming and connected to the charger.
    As for gaming on battery:
    You shouldnt do that a LOT because it causes RAPID discharge of the battery
    See 3B below::
    General consideration of your MacBook battery
    Contrary to popular myths about notebook batteries, there is protection circuitry in your Macbook and therefore you cannot ‘overcharge’ your notebook when plugged in and already fully charged.
    However if you do not plan on using your notebook for several hours, turn it off (plugged in or otherwise), since you do not want your Macbook ‘both always plugged in and in sleep mode’.
    Do not perform “battery calibration” on your current Macbook. There is no calibration of current Apple portable Macbooks with built-in batteries.
    A lot of battery experts call the use of Lithium-Ion cells the "80% Rule", meaning use 80% of the full charge or so, then recharge them for longer overall life. The main quantified damage done in the use of Lithium Ion batteries are instances where the internal notebook battery is “often drained very low”, this is bad general use of your notebook battery.
    All batteries in any device are a consumable meant to be replaced eventually after much time, even under perfect use conditions.
    If the massive amount of data that exists on lithium batteries were to be condensed into a simplex, helpful, and memorable bit of information it would be:
    1. While realistically a bit impractical during normal everyday use, a lithium battery's longevity and its chemistry's health is most happy swinging back and forth between 20% and 85% charge roughly.
    2. Do not purposefully drain your battery very low (10% and less), and do not keep them charged often or always high (100%).
    3. Lithium batteries do not like the following:
    A: Deep discharges, as meaning roughly 10% or less. Avoid this in all instances if you can. This is hard on your battery.
    B: Rapid discharges as referring to energy intensive gaming on battery on a frequent basis (in which case while gaming, if possible, do same on power rather than battery).
    C: Constant inflation, as meaning always or most often on charge, and certainly not both in sleep mode and on charge always or often.

  • Safe to remove battery while plugged in?

    I heard that you can greatly increase the life of your battery be removing it when the computer is plugged in. I got my powerbook just last February and I can already tell a great deal of performance loss in the life of my battery, so I just want to know if it's safe to take it out when I'm not using it.
    Thanks

    Oh yes. Just one caveat, should you lose power, the machine will almost instantly shut itself off. You have upwards of a couple seconds while the backup battery overcomes the loss of power. So keep the battery at your side.

  • T430 using battery while plugged in?

    I recently bought a refurbished t430 that's still under warrentee, and having a weird problem with it. Under normal use, the battery chargesas it should, but I've noticed while playing games, the battery drains as if it's running on battery power, but without the screen dimming. Has even had or heard of a problem like this? The AC adapter is the 65w lenovo one it's supposed have.

    At full load, the power consumption of the system is bound to exceed the 65W the adapter itself can deliver, so it has to draw upon the battery's supply of reserve energy for spikes of power consumption.
    If you remove the battery while using the 65W adapter, your CPU will throttle itself to prevent overexertion of the AC adapter.
    If you want to be able to run at full speed without a battery or be able to power the system at full load without draining the battery, you'll need to upgrade to a 90W adapter.

  • Dv8315nr drops to battery while plugged in, especially under load

    Have the dv8315nr and it keeps dropping to battery while plugged in, especially when the PC is under load, such as games or using CD drive.  The power block is ok, it has been tested with other power blocks and the issue still happens.  If you unplug the power at the pc and plug it back in, it will (most of the time) go back into a charging state.  I sent to hp while under the extended warranty and they sent it back with the diagnosis of "battery was bad, needed new battery".....and it worked ok until just out of warranty then started again. 
    I don't think it's the battery, since it happens with or without the battery in place (of course it dies completely when the power drops w/o battery in). 
    Has anyone experienced this and if so, have a method to fix it?  I suspect there is a hardware problem with the power supply in the laptop.
    This question was solved.
    View Solution.

    It sounds like the beginning stages of a bad power jack. That is the place where you insert the AC adapter into the laptop. The problem is very common and requires that a new jack be installed. Fortunately for you, the dv8000 has the power jack as a separate plug-in module...it does not require soldering just removal and replacement. 
    Here is an internet ad for a company that does the repair. I am not suggesting you hire them but they do post some nice pictures of the internal workings of the dv8000 series so you can understand what I am writing about. The repair job is only modestly hard; not nearly as bad as if soldering were needed. The part is readily available.
