If battery is in palce Powerbook G4 does not start

Hello,
I just had to change to AC adapter/recharger
Now my Powerbook G4 1.67 dual lawyer
will not start if a battery is in its compartment
tha fan goes wild for a minute of so then it shuts down
However, if no battery in the compartment, and plugged in with the CA Adapter/recharger
it works just fine
I have tried 3 batteries, and all give the same problem
I ran Hardware test, and all is fine
I reset the PRAM (while no battery in compartment) and I reset the PMU
Still no results, same problem
any ideas ?

The Apple hardware test doesn't test the charging circuit, so you need to debug it based on what's happening with the system. When it tries to start, with the battery in, the fans go crazy, and it shuts down sounds like a logic board issue. The fact that you tried 3 batteries with the same results doesn't leave alot of things to look at. There are 4 components, maybe 4.5 components to the charging circuit: power adapter, DC-in card, battery and logic card. Some suggest the PRAM battery should also be considered. So, adapter is new and runs the system without battery. That means DC-in card is working. 3 batteries don't work. All sort of points to logic board.
If the system is working on power, and you put it to sleep, with the white LED pulsating ... if you disconnect the power does the light continue to pulsate? If not, replace the PRAM battery (www.macsales.com has new PRAM batteries for some models). Then re-evaluate if it will run with battery. If not, then run only on power, or replace logic board.

    powerbook g4 - does not start up...it shows kernel panic screen...how do i fix/resolve this problem?

    In the overwhelming majority of cases, kernel panic indicates a severe hardware problem. Braby and Allan pointed to useful things. If you can boot from CD / DVD and reinstall without any kernel panic, then may be a software problem, but this is less probable. You must check, anyway.
    If you have a 2nd mac around and a firewire cable, you may try to restart the ill mac in target mode and connect it to a healthy mac to see whether it may be used in target mode.

  • My battery still does not start recharging when less then 10% charged

    Hi,
    I have been having problem with my laptop (Pavilion dv7) for the last three weeks if not more. Basically the battery does not start charging when it is less then 10% charged. I tried calibrating the battery and the problem seemed to disapear for some time. However after less then a week it starting doing the same thing again.
    When I try the battery healt teset (that comes by default with the laptop) it gives me a message that battery should be replaced and also gives me the warrenthy id. Should I go with the warrenthy id to the place where I bought the laptop to get a new one? Or is there anything else I can do to try and solve the problem.
    Regards
    Simon J.

    Call up HP Tech Support, provide them the warranty ID, to get your battery replaced...Given if your Laptop is not more than 1 yr old, as Battery has one 1 Yr warranty on it...

  • T400 does not start up with a battery and AC, but starts up with only AC.

    I bought T400, 7417-CTO in Jan 2010. My T400 does not start up with a battery and AC power. I tried to start with only AC power after pulling out the battery, it worked fine. Even when I inserted the battery in T400, which was running perfectly with AC only, T400 seems to lose the power - more strictly speaking, it kept stoping and re-running several times, and finally it dead.
    a few possibilities
    1) a battery is dead - but it does not explain the failure with both AC and battery
    2) some hibernation issue - I plugged in and out the DIMM, and clock battery. I tried to keep pushing the power button trick, but it didn't work
    3) Mother board failure??
    I really appreciate if you give me some advice on it.
    Wanyong

    Thanks for all your kind and helpful comments.
    Unfortunately, I don't have any friends who have Lenovo - or I don't have many friends here since I moved in the last summer. ;-)
    After purchasing a new battery, I will update it. Hope that this thread helps someone who had/will have same prob. as mine.

  • N8 - battery probably empty - does not start

    Hello.
    My N8 battery probably got empty during the night cause in the morning I found it switched off. I started to charge it but the phone does not start anymore. The little light blinks for a while and afterwards stops. I charged it for 2 hours and still it does nothing if I press switch on button. The screen is blank, no indication that it is in the charger.
    Thank you for any advises.

    If you've tried all the suggestions already made and still nothing, you'll find the problem is in the phone itself... I had a similar problem a little while back and took it to Nokia Service Centre for them to have a look and it turned out the phone was faulty and they replaced it for me... Too bad I hadn't made a back-up and lost everything... Good luck

  • Torch 9860 does not starts

    help!
    my blackberry Torch 9860 does not starts, and the red led blinking a slow time and 3 times faster
    I removed the battery and waited, when i put the battery back, nothing happens
    I installed the blackberry desktop, but it does not recognize the phone, not from any sign that is connected
    I tested with another blackberry and connected everything right, the problem is not the cable or pc
    when I connect it via USB the red LED blinks 1 time 3 times fast and slow
    when I try to start it nothing happens

    Hi and Welcome to the Community!
    Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain connected to a known-good wall charger (not PC USB):
    With the battery inside, connect your BB to the wall charger
    Leave it alone for 2 hours, no matter what the LED or the display does
    Remove the battery
    Wait 15 minutes
    Insert the battery
    Wait another 2 hours, no matter what the LED or the display does
    This has been known to "kick start" some BBs.
    It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
    Obtain a known good and already fully charged additional battery...use it in your BB and see what happens
    Obtain access to a known good and identical BB...use your battery in it and see what happens
    The results of this will indicate if it's your BB or your battery that has the problem.
    Good luck and let us know!

  • NEW IPHONE 3GS DOES NOT START

    I just got my new iphone 3gs yesterday and have not even had the time to have a nice look at it coz it just does not start.
    When I put the phone to charge the apple logo appears and after that just the sign of USB connector pointing towards itunes (with the itunes logo) appears and phone stops. I had it charged for more than four hours but I don’t see the battery charging status icon anywhere.
    When I press the ON switch on the top the same thing repeats itself meaning it gets stuck in the USB connector pointing towards itunes (with the itunes logo) sign. Totally confused and frustrated. Kindly assist. Lastly as i am new to the apple brand could anyone guide me towards the Software for the IPHONE 3GS i require to install on my desktop in order to sync,email etc.thanks for the advises in advance

    Obviously it's telling you that you need to connect your iphone to your itunes to activate it, otherwise it won't work.
    Firstly download itunes, under Downloads. then install then plug in your iphone, and follow the instructions to activate it. Then you should be set and start using the phone.

  • Screensaver does not start

    Hi, since upgrading to 10.5.1 my screensaver does not start either by hot corner or automatically. I can get it to test from the preference pane, any suggestions?

    Same problem here,
    I'm not sure entering/recovering from sleep has anything to do with the problem, since i sleep my powerbook running 10.5.1 every day, and the screensaver works fine.
    On my Macbook Pro however, (10.5.1) it seems that the problem occurs only after a few days of uptime (and of course, some sleep/wakeup sessions). After a reboot the screensaver/hot corners work again, but only for a few days..
    I use quicksilver to lock my machine using the screensaver, and not being able to do this all the time is quite annoying
    There are a few other threads about this, but so far no solutions...

  • My blackberry does not start up!

    Hi!
    My blackberry does not start up. I've charged the battery for 2.30 hours, removed the battery, tried whatever I could, but nothing, it doesn't work. Do you know how can I start the blackberry? 
    Thank you!
    Solved!
    Go to Solution.

    Are you using a wall charger or USB charger? Do you see any LED light when you put in the charger? Normally you should see a flashing orange light, when the battery is fully charged it should turn to green.
    However if your battery was drained completely and you are trying to charge via USB it will not be possible because USB uses power to initiate charging.

  • My iMac does not start.

    My iMac does not start. When I turn it on, it stays loading in the half and doesn't continue. Some days before I had updated my iMac to Yosemite 10.10. Everything was ok but yesterday I decided tu reboot it and when it was turning on this happened, it kept stuck at the middle of the bar. I have the latest model of MacBook Air '13.

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
    Step 1
    The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
    There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
    a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
    b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
    c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
    Step 3
    Sometimes a startup failure can be resolved by resetting the NVRAM.
    Step 4
    If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
    Step 5
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 6
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    Step 7
    If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
    Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
    If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
    If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 8
    Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
    Step 9
    If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.  
    Step 10
    Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 11
    Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
    Step 12
    This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 13
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

  • My iPad does not start. What can be the problem

    My iPad does not start. What can be the problem

    Does anything happens when you try to switch it on ? If not, then assuming that the battery isn't empty (and it can take up to 15 minutes of charging before it will respond), then have you tried a reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds, after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
