Satellite L755 restarts without warning

HI, my Toshiba Satellite L755 is 2.5 years old running windows 7 home 64 bit. The OEM battery had lost capacity over the 3 months. One day, the closed laptop.

Put on again, I learned the replacement battery sign in the lower left corner with the capacity of being shown around 45% remaining battery. In the coming weeks, it started happening more often. To restart once a day at first, he went to restart every few hours. The battery capacity is increased from 45 about 20%, so I decided to remove the battery and work on AC.

It worked well for a few days, but then one night the dreaded restart has begun. Initially, it was only once a day. Now, a week later, my system restarts every 3 or 4 hours. Upon restart, the screen displays windows stops unexpectedly, and if I want to start windows in safe mode or normally. When I select normally, sometimes, the laptop runs checkdisk.

Because of this annoying problem, I ended up also damage my 500 GB Toshiba canvio EHDD as I format the laptop restarts unexpectedly.

Help, please

For me that's not easy to tell if these reboots are related to electronic food and I can't say with certainty why this happens. In General, you should be able to use your laptop without any problems by using only the AC adapter. I have the same situation with my old Satellite A300 and there is no problem at all.

This sudden shut-off valve is a little suspect to me, and maybe it's that some unwanted hardware. I see two possible reasons for this: either is completely cut power or laptop turns off due to another reason which can be overheating.

When you take a look on LED panel when this happens, can you notice that there is no DC in LED?

  • How can I recover hal/dll library - computer restart without warning

    My computer kept restarting with warning message. Detectors of viruses and malicious software nothing - nothing did fall within the firewall either.  When we tried to recover to an earlier point (it started when Microsoft had us install malicious programs) the hal.dll file had been corrupted or deleted.  This message came when we tried a system restore.  We do not have a disc XP from Microsoft.

  • Pavilion 14-al015na: new HP laptop reboot without warning

    I would like to start by saying that I am not savvy computer very waves and too complex answers will just go over my head. Honestly I do not know if I chose the right subforum for it (sorry if I don't!). Please try to put the answers in stupid people talk

    I bought a HP Pavilion with a processor intel core i3 (this: http://www.johnlewis.com/hp-pavilion-14-al015na-laptop-intel-core-i3-8gb-ram-1tb-14-natural-silver/p...) there are less than a month and I barely use it's really for uni starts back. Despite this, I had problems several times with it restarts without warning, while I'm in the middle of something. I also had this error message once: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (bcmwl63a.sys) as it turns off. He also asked to be restarted for updates and just because he apparently wanted to basically all the time it is turned on.

    I moved all my documents, photos and music from my old laptop (also a HP) to my new but I have left the program etc. files behind. My old laptop had issues where it would freeze and become completely unresponsive (does not restart as in the case of my new laptop) and have to be turned off by the power button, and anything I worked on to lose and it was one of the few reasons I decided to replace it. In addition, whenever I turned on it he grew up a pop-up, the kind you see when you install a program. I uninstalled the program in question, but the pop-up persisted. I've always had a McAfee antivirus protection on all of my devices - computers of my phone, which was connected to the time - but I guess that something got through between the cracks?

    Basically, I would like to know if the issues with my new laptop are the result of a virus or not (the same who touched my old laptop?) and of course be saved or not. Thanks in advance,

    Estella.

    @leaf2,
    Thanks for joining the Forums HP, Estella.
    I'll be happy to help you!

    I understand that your laptop will restart without warning after posting the message-"(bcmwl63a.sys) SYSTEM_THREAD_EXCEPTION_NOT_HANDLED" once, it freezes constantly and frequently reboots, here's what I recommend that we do:

    According to my research, it could be a bad driver, the origin of the problem otherwise we will need to perform a test of hardware on your memory card, I'll let you know how to do this, later.

    To remove the bad driver, I recommend the following steps:

    1. Start Control Panel, click hardware and soundand then click Device Manager.

    2. Expand the node under network adapters, right-click the device entry, and then click on Properties.

    3. Select the driver, and then click Roll Back drivers, if it is gray in color (impossible to click) select uninstall drivers.

    Made the above, restart the computer and then go to the HP website and download the latest drivers for your network card: Click here.

    Keep me posted!

  • Satellite Pro started to stop abruptly without warning

    Hello

    Can someone advise me, I have a Toshiba Satellite laptop, it is around the age of 13 months, and he began to stop abruptly without warning.
    It seems to be when I run high processor applications.

    I have 3 questions,

    (1) it is first of all, this laptop will always be covered by the warranty, even if he is 13 months old?

    (2) is it a simple fix for this problem of overheating?

    (3) I looked online and it seems to be a very common problem with Toshiba laptops, has there been a recall on all models?

    Thanks for any help you can give me?

    > 1) the first is, this laptop will always be covered by the warranty, even if he is 13 months old?
    Standard warranty covers portable duration 12 months. If you didn t buy additional coverage then the manufacturer's warranty no longer valid.
    But in my country, the dealer covers the portable 24 months long then maybe you should ask your dealer for info.

    (> 2) is there a simple fix for this problem of overheating?
    Well, the temperature could be higher because of the dust and debris inside the cooling rack.
    You could possibly solve this cleaning fans and cooling grids. I use the jet of compressed air. This could help you as it helped me

    (> 3) I looked online and it seems to be a very common problem with Toshiba laptops, has there been a recall on all models?
    This isn't a problem common with Toshiba notebook but unusual for all series of laptops from all brands.
    After a while the debris may clog the cooling system because the cooling fans are always placed at the bottom of the unit.
    It is advisable to clean the fans from time to time to ensure good air circulation.

  • Satellite L300-1AS - Wireless disappears completely without warning

    I got underway, but annoyingly intermittent problems with the wireless on my laptop. I got it since Dec. 24.

    Basically, I have days/weeks of use with no problems, then, without warning, the wireless disappeared completely. He won't let me fix the usual channels, or it will show even the laptop with the ability to be wireless!

    After I restarted the laptop, it still does not work, but then through the repair process, he said that wireless capability is turned off!

    First, are there any patches to this?
    Secondly, any ideas how my laptop tells himself to turn off my wireless?

    It is a pretty big problem for me because I don't use the internet a hell of a lot.

    Thanks in advance

    Hello!

    In my view, this could be also a problem of router then make a day first firmware. You can find it on the site of the factory.
    Turn off the features of security as a hidden SSID, MAC address filtering and so far. Just to test, it perhaps is the problem.

    As said by Akuma, update your WLAN driver and update your BIOS. The two you can find on the Toshiba site:

    I hope one of these tips can solve the problem.

    Good bye

  • Satellite C660-1F1 has start off without warning

    Recently my laptop Satellite C660-1F1 start off without warning and I read in other forums that it could be an overheating problem.

    You have advice on how can I fix?

    Thank you
    Paul

    Yes, one of the solutions could be the cleaning of the cooling fans.
    Dust and debris inside the unit and cooling modules may affect the functionality of fan.
    The air circulation could be affected too then remove the dust using a jet of compressed air.
    Its good tool to get these issues resolved without separate laptops.

  • Satellite L755 - 16L - new installation Win7 without recovery option

    Hello...

    I have a Toshiba Satellite L755 - 16L.
    I want to re - install windows 7, but recovery option will erase everything... I don t want to use it, I saw a key at the bottom of the laptop for win 7, saying it is oa mea?

    So is there a way that I could do without clear all.

    Hello

    Please visit http://aps2.toshiba-tro.de/kb0/HTD1303440001R01.htm
    You will find all the HARD drive recovery facility information and accurate information which will be deleted exactly (see Note).

    Product key down means that you bought laptop with preinstalled OS and valid license. This key belongs to the version of the OS preinstalled. Don t think you can use it for the activation of the operating system if you try to install the version of the OS using the Microsoft installation disc.

    > So is there a way that I could do without clear all.
    I put t know what do you mean under everything.
    If you want to have own pre-installed OS still best option for you is to back up all important data on external device and after installing the OS, you can copy it to computer s portable HARD drive.

  • L50-B05C satellite crashing while gaming - black screen without warning

    Laptop Toshiba Satellite L50-B05C crashing
    I write because there is no section of series B in the section.

    The laptop is 2 months old and has just recently been crashing (blacken off instantly, screen) without warning when I play a game.
    It had worked perfectly in these games until about a week ago.

    Use CPU, memory and disk are all weak, so I have no idea of what is happening.

    Any help would be greatly appreciated, thank you.

    I write because there is no section of series B in the section.

    Just FYI: it is an L series (L50- xxxx)

    The laptop is 2 months old and has just recently been crashing (blacken off instantly, screen) without warning when I play a game.

    Have you noticed a temperature higher while gaming?
    I guess that the laptop automatically stops due to the higher internal temperature.
    This is nothing unusual if the temperature is too high... the laptop would shut down to prevent the equipment from damage...

    Try this:
    Go to advanced windows power options and reduce the max CPU performance at 90-95%
    In addition to change the cooling method for: performance.

    I would also recommend to check if fans and the vents are not clogged with dust...

    I'm not sure where you live but in my country, the temperature is currently very high and I guess it's really hard to cool the internal parts and to maintain the temperature of the low laptop

  • Satellite L300D continues to go off without warning

    I've had my Toshiba Satellite L300D for a month, and recently he continues to go off without warning.
    I don't know what to do as this continues to be between 3 seconds to turn on the laptop and 5 hours to turn on the laptop.

    What should I do?

    The laptop gets hot? Did you check that?

    Maybe the laptop gets hot because dust blocks the air flow in cooling assembly. You can clean it with a jet of compressed air, that you can buy at a computer retailer. This could blow the dust from the ventilation of cooling.

    Also, make sure that it is enough free space around the laptop.

  • Satellite P20-521 turns off randomly without warning

    Computer shuts down randomly without warning. I also had a few blue screens of death last week.
    To restore using factory settings.
    Or should I return my Toshiba laptop

    Hello

    As Johnny writes that you should try to clean the unit. I used Satellite P20 for two years and remove the cooling in the lower corner, I found a lot of dust inside. After that cleaning of the laptop was much more calm and cooling fan did not run at full speed as before.

    I imagine that your laptop may not be cooled properly and the result is overheating. Your first step should be to remove dust. Look at how the laptop runs after doing this. If the laptop starts to cut again please write us again.

  • Satellite Pro L630 close without warning

    my laptop has been close without warning - today got an error message on any ideas - failure of the cooling system

    If it is the fan / repairable or perhaps other components default?

    Hi Yannos

    I think that your laptop turns off automatically due to high temperature.
    Probably the cooling fan (cooling module) is no functions and therefore the CPU cannot be cooled properly.

    The notification that received you today confirm my hypothesis.

    In my opinion, the cooling module must be checked and probably replaced in order to solve the problem of cooling.

  • Satellite L755 - card wireless driver is corrupt

    My Satellite L755 was fine yesterday, but this afternoon it started with this disturbing of the yellow dots on the wireless signal meter in the status bar. I ran to the resolution of problems, followed her, and that is to say that the wireless or LAN driver is corrupted. I checked, it is an Atheros chipset, so I got a mate to download the latest driver on the site of Tosh.

    I transferred via an sd card, and it's an Assistant auto running. He ran, the pilot has changed (I checked the dates), but the laptop has exactly the same problem. I know it's windows, as on the start screen, where the windows password box appears, there is a WLAN box and who is showing the complete connection.

    What should I do now? The final move would be to transfer all data on an external drive and go to the total reload of windows on the recovery partition, but it would be a radical gesture.

    Anyone has a suggestion for a less stressful recovery?

    Wireless network adapter installed and listed correctly in the Device Manager?
    Try please restart your router and check the connectivity again?
    Is visible WLAN for your laptop after reboot of the router?

    Try please test with some other WLAN or your WLAN WLAN functionality but without WLAN security.
