Satellite A300 shuts down when the power adapter plug is inserted

Hi people
When i connect power cable to my toshiba sat a300, it shuts down immediatly. I can use it on battery normally without any problems.
When i boot in the safe mode, it works properly without any problem with the AC Adapter connected to the Notebook.
OS is Windows Vista
What is the reason? what i can do to solve this problem?
Thanks

I can start the Notekook with the AC Adapter plugged, but it turns off before to reach the Welcome Screen or reboot. I tried straight to install Windows 7 with a another HDD . As soon as only the installation files are loaded, the system starts again. I do not reach times the beautiful blue window, of where the actual installation can be started.
thx

  • New iBook G4 - shuts down w/o power adapter

    I helped set up a brand new G4 iBook for a friend (10.4) purchased today. When the power adapter is unplugged the computer immediately shuts down. The battery indicator shows 100% charge. What are the proper steps to diagnos/fix the problem? Or should they return it?

    I would take it back. It could be that something as simple as resetting the PMU will take care of it. If that doesn't do it, this symptom could be a logic board problem (it was with mine).
    Let Apple figure it out and/or have them replace it.
    By the way, the iBook G4 Discussions can be found here. (This is the iBook G3 dual USB discussion area.)

  • My MAC Pro shuts down when the battery still have 50 minutes life.

    My MAC Pro shuts down when the battery still has 52 minutes life without any warning. Does anyone have this problem? BTW, it is less than one year old.

    You must have a MacBookPro, right? MacPro's are big desktop models.
    Try the MacBookPro battery forum or their Usage forum.

  • Is it better to use my Pro with the power adapter plugged in or out?

    After charging my MBP's battery to 100%, which is better?
    - keep the power adapter plugged in to the laptop and resume using until you want to turn off the laptop
    OR
    - because the battery is already at 100%, unplug the adapter and resume using until you feel like you should charge the laptop again (maybe around 80%-90%)

    If you are convenient to an AC outlet it's fine to use the adapter. However, keeping the AC adapter connected will not have an adverse affect on the battery. Once the battery has been fully charged it will stop charging. Recharge will begin once the battery's charge drops below 95%. LIthium-Ion/Polymer batteries do not exhibit memory effects.

  • Can get past the "Power adapter plugging into wall" icon

    I just got my brothers older 60gb Photo ipod and am trying to get it working on my computer. Did the whole restore thing, but now it is stuck at the Power adapter plugging into wall icon. I didn't have the original wall plug so I got a universal one at Radio Shack. Only the ipod still has the darn icon on it and I can't get past it. Any suggestions>

    Lets do a trick. Connect the iPod and the cabel. The USB connector has 2 prongs that stick out a little more than the rest the goal. is to push it in a little so it charges but does not sync. Give It A Try.

  • Why does Satellite Pro A300 not start when the power button is pressed?

    Suddenly my new Satellite Pro A300 will not start correctly when the power button is pressed. The situation is this: When I press the power button the Toshiba opening picture (Leading Innovation) appears and disappers quickly. Then there is a black screen for about 30 seconds. Then there is a rectangular frame with the text Microsoft Corporation underneath. And nothing happens however long I wait.
    In order to get on with the starting proces I then shut down the computer by pressing down the power button until the computer stops. ("The hard way to shut down")
    Now I press the power button shortly to turn on the computer. Then the computer starts normally with the Toshiba opening picture and after a few seconds I am asked to open the computer in safe mode or in normal mode. I now choose to open in normal mode and the computer opens normally and is ready to work.
    What shall I do to get a normal start procedure?

    When notebook starts normally (after choosing normal mode) shut down your notebook properly using START > Shut down option. Next start should be normal.
    When the OS is switched down on irregular way you will be always asked how to start it again (safe or normal mode).
    The same happen on my Satellite A300.

  • Is there a way to have the nano automatically shut down when external power is removed?

    My old ipod shut down when I disconnected the external power, a useful feature when using it in the car.   Can the 6th Gen nano be configured to do this?

  • Why does my macbook only turn on when the power adapter is plugged in?

    The battery life says its at 73% and climbing but whenever I unplug my power adapter the mac automatically shuts down and if I try to turn on the macbook without my power adapter plugged in, it wont turn on. How do I make it go back to where I can turn the mac on without it being plugged in? Thank you for your help!

    I would try two things the first being resetting the System Management Controller:
    1) If the computer is on, turn it off.
    2) Disconnect the AC Adapter and remove the computer's battery.
    3) Press and hold down the power button for 5 seconds and then release the button.
    4) Reconnect the battery and AC Adapter.
    5) Press the Power button to restart the computer.
    If that doesn't work I would recalibrate the battery.
    To calibrate the battery:
    1) Plug in the MagSafe power adapter and fully charge the MacBook or MacBook Pro battery until the light on the MagSafe connector changes to green and the Battery icon in the menu bar indicates that the battery is fully charged.
    2) Allow the battery to rest in the fully charged state for two hours or longer. You may use your computer during this time as long as the power adapter is plugged in.
    3) Disconnect the power adapter with the computer on and start using it with battery power. When the battery's charge gets low, you’ll see the low battery warning dialog on the screen.
    4) Continue to keep your computer turned on until it goes to sleep. Save your work and close all applications when the battery's charge gets low and before the computer goes to sleep.
    5) Turn off the computer or allow it to sleep for five hours or longer.
    6) Reconnect the power adapter and leave it connected until the battery is fully charged. You may use your computer during this time.

  • Why does my macbook shut down when the lid is closed?

    Hi,
    I have a Macbook Pro (mid-2012) running 10.9.1
    Last week out of the blue, the Macbook started shutting down whenever I close the lid.
    When I open the lid, the logon screen appears (as if it's been asleep as normal) but almost immediately reboots itself.
    Has anyone else got the same issue? Any idea how to resolve?
    Thanks

    If after you open the lid you do get the login screen, almost immediately, but then it restarts your system is not shutting down when you close the lid. It is going into a sleep state but then crashes when trying to come out of that sleep state. There are quite a few posts on this problem and it seems to be caused by the system going into the Deep Sleep state also known as the hibernate mode. That is where the contents of the RAM is written to the hard drive and the system suspends supplying power to the RAM chips so the system uses even less power then in regular sleep mode.
    That is only supposed to happen after the system has been in the regular sleep mode for an extended period of time.
    To check the state of the huiberbnate mode open terminal and type in, or copy and paste, this command.
    pmset -g | grep hibernatemode
    To check the state of all power management settings use the command.
    pmset -g

  • Server Shutting down, when the Concurrent Users are more

    Hi,
    We are working on EP 5.0 SP5, our problem is that if the concurrent users are more automatically our LDAP or Portal is shutting down (approximately 300 or above..).
    For this problem… where we have to check? help can be appreciated...
    Regards,
    Sudhir

    Hi,
    If you portal is shutting down when it is getting a high load I would look at the memory settings defined in the configtool (if you are using a service or the startupframework) or the go.bats if you are running them manually. I would assume that the problems comes from the java process not being able to get enough memory, so try increasing the heapsize parameter Xmx (?)

  • Why is my phone shutting down when the battery is @ 94% doing anything with it? Is the recent upgrade a chance to get us to buy and Iphone 4?

    My I phone 3ga 16gb shuts down when I open any app and surf any webpage unless plugged in to the charger. I have 94% battery and as long as I don't do anything with the phone except answer it when I get a call it will stay on. I recently upgraded it to the 4.3.5 os and was wondering if that is my problem? if it is how do I get it back to an older operating system?

    Highly unlikely that 4.3.5 itself is the problem as there would be millions with the same problem... there are not.
    Restore your 3GS from your backup.  If still a problem, restore as new, i.e. without your backup.  One of those will most likely solve your problem.  If not, you may have a defective battery.

  • MacBook Pro keeps shutting down when the screen is closed

    Hi, I have a 2011 15inch MacBook Pro and it keeps shutting down rather than sleeping when I shut the screen. It also shuts down when left for short periods of time rather than sleeping. I have updated it yesterday and still the problem happens. I also installed a virus check to see if that was the problem and it didnt find anything it could fix! Any help is much appreciated!!!

    Try a SMC reset.  That may correct the situation.

  • HT3131 how can i run in clamshell without the power adapter plugged in?

    just what the question states..I dont want to have to always connect the power adapter. thanks

    thanks this works well with the power adapter pluged into the mac, but I am looking for this exact setup without the need for the power to be supplied to the mac.
    in otherwords, run it off the battery only.
    I want to think that there is either a preferences setting, or function to be able to do this.
    currently it appears that the mac will only run in the configuration with external perpherials with the power supply.
