Satellite M60/M55: Turns off after power loss

My M60 sometimes turns off immediately after unplugging the power supply (AC power or plug the laptop CC), instead of out on the battery even though the battery is fully charged.
The battery is OK & the laptop starts regularly on the battery after pressing the on switch.
The Toshiba Power Saver seems to work OK & I have the latest version of the BIOS.
I always save my work before unplugging, but again, I do not like this behavior & would appreciate some good advice.

Satellite M55 turns off by unplugging the power cable to unplug my laptop making rather that to the battery, my laptop will often simply turn off even though the battery is fully charged. Other time things work as it should.

I had the motherboard replaced for another reason and was quite surprised to notice the problem after a replacement (but without reinstalling OS).
The main suspect is the TPS and its pilot; A few months ago, a new version is released the Toshiba support site for M60 (although file dates are not fresh, and I think that I have installed this version earlier).

So, I removed the GST and the GST pilot. I tried several times and it didn't happen again. Not even when I reinstalled the.

During the test, I have disabled the HD write cache to avoid file corruption problems (but this slows down HD operation, particularly of hibernation).
I don't know if it works because also earlier the computer would be closed only occasionally, not all the time. But this may be a clue in case you have this problem. If you do, please test and report the result, no matter what the result is.

What to say dude. The problem is that this problem occurs ONLY occasionally and so it's not easy to find the real reason for these cases.

However, I would try to give some useful advice, but first of all, it would be useful to know how old your battery.
Fact is that batteries old and stressed loose clean performance very quickly.
My battery is about 3 years and my laptop running on battery for 10-20 seconds even if it s fully charged. The performance is simple very low!

On the other hand the problem could be related to faulty electronic power to the Board of Directors
As you can see it's not easy to tell what's exactly wrong and as already suggested in other threads (locked), you should ask a technician for a control of the laptop.
The guy could run diagnostics tests and can locate the fault.

Best regards

    Hello

    I agree with tom, and the device must be checked by the service. I think there is something wrong with electronic power supply. If the battery has only 20% of capacity by removing the AC adapter / CC unit should not stop.

    I hope that you will find what is the problem.

  • Satellite A60-712 - turn off after 2-3 seconds

    Hello everyone.

    I am trying to fix this Satellite A60-712; He came to me without feeder, but I found a compatible and it seems to work: CC in LED lights up and the battery starts to charge.

    My problem is that this starts Mobile for awhile, radiator begins to turn, all the lights are normally, but, all of a sudden everything turns off after 2-3 seconds. I have observed that this machine has only one slot of free RAM and noted that it has integrated the module memory motherboard; that would be the problem? Or another reason?

    Could someone help me?
    Thank you.

    Hello

    > it came to me without feeder, but I found a compatible
    Can you please test it with a Toshiba original AC/DC adapter? The same thing is happening?

    If the laptop has already integrated memory motherboard there is no problem. Alternatively, you can use the laptop without additional RAM module.

    In the worst cases, you need professional help of an authorized service provider. :(

  • Satellite Pro L650 turns off after start; DC In and Power LEDs blink on stop

    A friend Satellite Pro L650 having worked well until yesterday, all of a sudden turned itself off. Now, at startup, it lights up normally for about 10-15 seconds before turning off suddenly. Turned off, the DC in white/blue LED and the orange Power LED Flash on a broad set of intervals of approximately one second. This extinction happens if I leave Windows or press F2 to enter the BIOS setup.

    I guess this blinking is intended to serve as a kind of diagnostic code, but I have yet to track down what it means. Can anyone help?

    To avoid confusion, power without the product stack the same, sudden stop experience, except the two LEDs remain solidly lit this time. With or without battery, trying to turn on again immediately after that a shutdown produced no response at all. Remove the power cable and immediately it reconnect again and turn then produced a brutal power off, but in less than 5 seconds. More wait between attempts to market seems to give a little longer powered on State, but without fault, the machine turns off just suddenly. With its short time 'turned on' we are talking, there cannot be any kind of thermal protection?

    I had an old Satellite L450D lying around that uses coincidentally the same AC PA-1750 adapter, but use it made no difference. Of course, the battery does not have the L650!

    The only previous numbers, that I am aware of this machine have been intermittent case of Windows reporting "Plugged in, not charging", but as my friend use it exclusively on the network, it was not a problem.

    Your thoughts will be greatly appreciated...

  • Satellite M200 screen turns off after that start & battery does not charge

    Hello, I am from Jakarta, Indonesia
    I have a problem with my Toshiba Satellite M200 Notebook (running Windows 7 Home Premium)

    After I press the power button to the top of my laptop, it works fine display BIOS and Windows startup screen.
    but after that my monitor off all of a sudden when Windows is supposed to show the login screen.

    Sometimes, the monitor doesn't turn off, but shows a lower resolution (I don't know exactly what resolution, 1024 x 768 or 800 x 600, i use maybe 1280 x 800)
    so the only thing I can do is, press the power button to stop bad then press power again turns on, my monitor works normally
    try to stop and then turn on again in a few hours later, problems still comes once.

    from the moment where I install Windows 7, I use 8.15.10.1930 version of the driver (downloaded from Download Center of Intel, which included Assistant TV Intel)
    2 days ago, my friend told me that I should install the driver from the Toshiba site support, so I went to csd.toshiba.com and download the 8.15.10.1825 version of this site (which is not included Assistant TV Intel)

    my monitor works normally after I installed the driver I of csd.toshiba.com, so I think that the problem because the Intel TV Wizard somehow messed with my laptop. But this morning this problem once again, my turns just monitor suddenly...

    In addition, this problem seems to be my battery was unable to recharge, my completely reloaded Windows shows, but when I plugged my AC adapter,
    There are 15-20 minutes before my laptop turns off automatically

    Three months ago, I just brought my laptop to the local Service Center of Toshiba and bought the new motherboard to replace my old mobo (which have a VGA problem too!)
    Is there something I can do (related to Windows or driver/software) or I can bring my notebook at the center of service again?
    are they somehow an incorrect wiring when replacing my motherboard?
    and am I need to replace my battery too?

    I use this laptop for about a year and a half and there is nothing wrong with my battery before replacing the motherboard

    any help would be appreciated :D

    Hello

    Talk about your screen, the a graphics driver causes this malfunction with resolution and turn off. Go to the page of the toshiba driver and download the correct Vga driver for your model. I see, you are running Windows 7, if there is no driver for win7, try the vista driver.
    On your power supply, you have used for the year and a half and he is released in 20 minutes, there is nothing strange. It's standard for power supply operating period, need to be replaced. Just to be sure, you can check with a new battery. You will see that the trick works as expected.

  • Satellite A100 - monitor turns off after reboot

    Not here a load of HARD drive, also if the output of the BIOS not are displays logo. Just how to work again with turn off phone then turn on again. I also try external VGA display with cable (VGA VGA) have same problem.

    I try to put the connector again still.

    Hey mate,

    If you have the same problem on an external monitor I think that it s related to the motherboard or something else. He should t be a problem of the internal screen I think

    It's really hard to say something about it, but you can try to update the display driver and BIOS. The two you can find on the Toshiba site.
    Check it!

    In addition, it would be interesting to know what operating system you are using. Operating system preinstalled Toshiba?

  • Satellite P300 - randomly turns off the power when connected to the external monitor

    Hello

    I have a Satellite P300, Intel Core 2 Duo T9400 2.53 GHz, 4 GB RAM, ATI Mobility Radeon HD 3650 512 MB, running Windows 7 ultimate x 64.

    Recently, I bought an AOC v22 led screen and connect my conputer via HDMI. Everything works fine, but sometimes my computer off just randomly. I might have something to do with my computer overheating, so I clean the fan, but this was not good.

    I think it has something to do with the LED screen because my computer was never off his own.

    Hello

    So this also happens if you n t connect laptop to external display? So, you can determine what is causing this problem.

    If the computer laptop doesn t turn off without external monitor, you should try to update the BIOS and the display driver. Two updates that you can find on the Toshiba site:
    http://EU.computers.Toshiba-Europe.com-online decision-making supported Downloads & => Download drivers

    You close the lid if you have connected the external monitor?
    What operating system do you use?

    In addition, it would be interesting to know how you clean the laptop. That's why I use the jet of compressed air that can blow the dust from the cooling fans and you don't have to disassemble the laptop.

    Good bye

  • Re: satellite A300 screen turns off after the toshiba logo, will not boot from the CD/DVD

    Hello, I have this problem with Toshiba satellite A300.

    I deleted several files and folders of my drives C and E. To restart the computer, it only shows the Toshiba logo then a slightly gray white screen on a thorough inspection. Whenever I press CRL + ALT + DELETE, the computer restarts and behaves in the same way.

    I tried to use an external monitor, but there is no difference. The tent to start using a CD/DVD, same behaviour occurs, it does not start and screen remains blank after the Toshiba logo, I tried even to change g the order of boot, but in vain.

    What could happen?
    Thanks in advance.

    Hello

    It seems that you deleted system files and Windows no longer starts. Have you tried to restore the disk image factory settings or hard drive recovery? Or do copy the Windows installation... It is easier to reinstall rather fix the problem.

  • Satellite L650 - Touchpad turn off after BIOS update

    Hello
    I recently got a new laptop, a L650-1CN,.
    I run different types of software from Toshiba, and one of them is Tempro,
    He shows me messages when a new update is available.

    Today I saw the message that a new BIOS update v.1.80 was available.
    I downloaded and installed. After installing my laptop closed. Then I started again.
    But after a few minutes, I noticed that my touchpad disable itself more.
    I usually use a logitech wireless mouse.

    Now, I wonder if I should do a system restore and not install this update of the BIOS or find another solution for this problem. Because it's really boring.

    Thanks in advance.

    Hey Buddy,

    Usually the touchpad disable automatically if an external mouse is connected, but only if you enable this option in the touchpad settings.

    I also use an external Logitech mouse and have enabled this option. You can find it in Control Panel > mouse. Go to the device settings tab and mark the internal pointing device option disable when the external USB pointing device is attached.

    I hope it works :)

    Hello

    > and clean any dust
    How did you do that?
    Usually, you can use jet of compressed air to clean the laptop and remove the dust that blocks the fan. That is why it s not necessary to disassemble the laptop as you can read here:

  • Satellite L20: Can I disconnect devices such as USB mouse without turning off the power?

    Hi all.
    I am owner of laptop Satellite L20. I always turned off power to my computer when I need to connect or disconnect a USB device. Some devices have a special icon on the toolbar disconnect them, but some don't (FDD USB or flash drives). Can I disconnect and connect devices such as mouse USB or Scanner wihtout turning off the power?

    Hello

    You can disconnect the external USB devices without turning off the unit, but you must use the option "remove hardware" before you cut the material.
    The icon "Remove hardware" usually appears with resources such as hard drives or USB key have the ability to buffer data. It of necessary for this buffer to the device before emptying it is disconnected

  • Satellite A100-812: screen brightness does not not & screen turns off after a while

    Some power management features do not work after a bios update (5.90).
    The display brightness can be changed in the power manager, or the top menu system. In the power manager, the cursor can be moved, but the brightness is not set. Toshiba menu system appears to hang on trying to change the brightness with F6 - F7 and won't move the cursor.

    In addition, the screen does not turn off after the set amount of minutes in the power manager.

    What is going on? How can this be repaired?
    Thanks in advance.

    Hello

    Some questions; Why you have updated the BIOS?
    Are you sure you used the right BIOS?

    In my opinion you shouldn't t to update anything if the laptop works properly!

    However, try to access the BIOS, set the default settings and save the settings before exiting the BIOS.
    If this does not help, I would pick up the laptop with the Toshiba Recovery CD.

  • Y450 screen turns off after 5 minutes, set to never power settings

    The display on my Y450 turns off after 5 minutes if it is connected or not. I changed the power settings on all levels of the power to never turn off the display, but he keeps doing. I thought that maybe it had something to do with windows is not fully updated so I did it earlier today, but it has not changed. It doesn't matter whether the system is energy saving, balanced or a custom.

    I don't know what to do to stop it, but it's annoying when I play videos and turn the screen on every 5 minutes. Is there another program I'm missing that somehow overrides the power settings?

    You may also need to change the power settings for the windows power management and lenovo power management.

    We also know, that the problem persists only watch movies?
