Satellite P750-114 - starting problems

I have a Toshiba P750-114 laptop which does not initialize battery at all and will only boot from AC if it was first disconnected and I ve pressed the button for a few seconds to clear the residual charge.

If I try to restart of sleep/hibernate, or even stop but left the supply cable from when it was already running, I get only the power LED and the fan is running, screen stays black.
If I remove the power, press the power button, power adapter supported then press the power button, it will start and run again without any problem until its judgment.

I tried to turn it on with a different tested battery and power, but it apears to not make any difference.

I ve read that no display/fan & power work was a sign of failure of the motherboard so I had checked it by a laptop repair shop / local PC (as the laptop is not under warranty) who found the Ribbon of touch panel was apparently causing a spark and that has been fixed, but they didn t find something else and that fix hasn t has really changed anything in what concerns start the laptop.

The laptop is running Windows 7 family and has very few programs installed, but all software is geniune.

I would really like to know what causes the problem because even though I can start it every time very well following the off unplug power on in-feed-ins on routine, I want to know if I'm just prolong the inevitable collapse or is it ok/fixable?

Thank you all for any help you can give.

I think if the guys at repair shop could not say exactly what is causing this problem, I doubt someone here in the forum would be able to provide a notice of right to 100% on this issue.

It is not battery or AC adapter problem.
Another part seems to be affected. There is not a lot of parts that could cause issues such as: RAM or motherboard are for most of the parts that might cause strange problems for laptop.

P750 isn't very old series, so guarantee seems to be valid
I recommend you call a Toshiba authorized service center and explain exactly the problem. Maybe they could reproduce this

  • WEb camera initializtion failed in Satellite P750-114

    Dear all,

    I am facing a problem with the webcam in my Toshiba Satellite P750-114. The laptop is less than two months the webcam was working fine, then all of a sudden it stopped working. The error message is "Web camera initialization failed. Please check your device and restart the application or computer. The Microphone works well, since it is linked to the web camera device. The operating system is Windows 7 64 bit. It seems that the operating system does not see that there is a webcam more. I tried the following things:

    1. I uninstalled the web camera driver, downloaded the latest driver from Toshiba Web site (the link is http://uk.computers.toshiba-europe.com/innovation/jsp/supportMyProduct.do?service=UK) and installed, but it did not work.
    2 - I have restored the original for the laptop settings, but still the webcam does not work.

    Two ways that I use to test the web camera: the Skype and Start/Toshiba/Utilities ' Web Camera Application"

    Please if anyone has an idea on how to solve this problem, the laptop is band again and it is fantastic, but this problem is annoying. I searched the Internet for similar problems, some Toshiba models suffer from this problem but not P750-114.

    Help, please

    This means that you have installed the OS using HARD drive recovery facility (factory settings)?

  • Satellite P750-114 - disk space to the critical level

    Hello

    I recently bought by Satellite P750-114 and now I get a message from toshiba Tempro my partition is cricial level as it reached 90% or more.

    Could someone help me with this please? Why did I get this? something wrong?

    To be honest I n don't know what the problem with Tempro, but this tool is somewhat strange. Nothing is false, then there is no reason to panic.

    Believe me best you can do is to remove it. In General, it is a nice and useful tool, but you don't need to all n.

  • Re: Satellite P750-114 - WLAN need driver

    Hello

    I really need help to find the driver on the right wireless for my Satellite P750-114-PSAY3E-02D002EN. I went through the trouble to install Windows 7 without using the recovery disk that you can get from the hidden HARD disk (I had 300 GB of files I didn t want to lose) and I got a nightmare to find the drivers for this laptop. (you mind I was warned by friends that Toshiba can be a real pain, but it's actually an understatement).

    Now (after a few days?) I m at the point where most things work outside my wireless.

    I ve found an old diagnosis tool PC Toshiba which is a bit difficult, but he said it s a realtek driver that I need, but I can t say that and that support Toshiba installs, I downloaded and then nothing happens. All suggestions are welcome!

    Thaaanks!

    According to specification for laptop, your laptop has Atheros WLAN with integrated BT card
    For WLAN driver check Toshiba download page - http://www.toshiba.eu/innovation/download_drivers_bios.jsp or WLAN Portal directly - http://aps2.toshiba-tro.de/wlan/. I think that here you can find the Win7 drivers.

  • Satellite P750-114 - extension of battery?

    Hello

    I was wondering if there is an extended battery available for Satellite P750-114. I can't find one on the Toshiba site. Are there any other sources I was able to find one?
    Thank you

    Hello

    I checked the specifications of other models P750 and their options but for P750 everything at the moment, only a battery 6 cells is available. There is therefore no battery 9 cells with a higher capacity.

    Maybe that Toshiba will develop such a new battery more wait to let s ability what will happen with. But on the other side, I must say that the Satellite P750 is a great piece of hardware, with very fast components for multimedia, games, etc. It s not the best laptop of Toshiba for mobile use of the battery life is not so important for this model in my opinion.

  • Satellite Pro M10 - starting problems

    Hello

    I have a Satellite Pro M10, only 2 years old, but has big problems at the start line.

    The message that appears when you turn on it is:

    Now, I talked to a few people and they all say I need a new drive hard etc., but I don't see how replace you it as it looks like it is built in instead of something that can be drawn.

    Also I don't have a system disk, and the guy who provided it has decided not to return my emails?

    Can anyone help please?

    Chris

    Hi Chris,

    It is possible that this notebook you trying to boot from the CD rather than the hard drive. Check in your BIOS settings to make sure that the boot order is correctly specified as HD first. I would not recopmmend change the hard disk at this stage, since it would mean having to restore your system from a recent backup (if you have a) or re-installing the CD recovery.

  • Toshiba Satellite pro sp6000 starting problems

    Hello

    I had problems with my sp6000 - it refuses to turn on most of the time. 1 in every 100 tries it could turn as nothing ever was. Normally if the green light turns to less than second, then disappears.

    I feel it maybe to do with the cdr/dvd combo player - as he reacts differently when it is deleted, tho I don't have another disc at hand to test this theoretical plan.

    Thanks for any help,
    Toby

    Hi Toby

    If you think that the optical drive is the problem of your machine, try simply plug and try to start without him. That is supposed to work perfectly.

    Good luck

  • Satellite P750-13N starts slowly

    Hello

    I bought a new computer for my birthday earlier in the month. I installed all my software and transferred all my data from my old laptop and I noticed after a week or so that the start-up is time consuming.

    Basically, once that windows loads, theres a circle over the wireless icon and it seems to take ages to locate my wireless network. I try to load firefox, but it dosnt open for at least 5 minutes, and nothing responds for about 4 or 5 minutes.

    I tried to do a clean boot, and although it seemed better, I can't seem to locate the problem. I uninstalled AVG and tried to uninstall most of the bloatware without success. If I do a clean install, it will be the second time I did and I really don't want to go that route.

    Can someone tell what could be wrong with my laptop.

    The sysinfo are:

    Hello

    Your laptop starts slowly because your system loads a lot of junk at the beginning.
    First of all, I recommend turning off some process that would be loaded while the laptop starts.

    Launch msconfig (in the search type msconfig) and go to the Startup tab.

    Now you can uncheck certain processes is not necessary.
    I would like to disable all Apple processes... they don t had to be loaded at the beginning

    + C:\Program Files (x 86) \Common Files\Apple\Apple Application Support\distnoted.exe +
    + C:\Program Files (x 86) \Common Files\Apple\Apple Application Support\APSDaemon.exe +

    Also turn off steam.exe

    After restarting again uncontrolled processes should not be loaded

  • Satellite P750-114 - display driver stopped responding

    Hi, I played a called game football coach and all of a sudden I got this message that brought me to the desktop.
    "display driver has stopped respinding and got" "NVIDIA Windows Kernel Mode Driver display driver, Version 2.67.44 no longer and was retrieved successfully.

    No idea what it is and how it can be solved? I have recived this many times while playing. This would mean the faulty laptop? Thank you

    Hi naz90uk,

    The problem is related to the nVidia display driver and I recommend reinstall the display driver if you get this error several times.

    You can download the last display on the official website of Toshiba driver:
    http://EU.computers.Toshiba-Europe.com > support & downloads > download drivers

    But remove the old display driver before installing the latest version. You can do this if you go to control panel > uninstall a program.

    Check this box!

  • Satellite P750 stops at the start of the 1st time but then works great 2nd time

    Hello
    My Satellite P750 always stops on the first time every day, but the 2nd boot works fine and no other problems...

    I press the Start button and it runs for maybe 10-20 seconds then stops... She does both on battery or power outlet...

    If I try to start again after that, it starts fine... sometimes, it gives the possibility to start in safe mode, or run the Startup Repair tool, but it always starts well and works normally...

    I tried to start repair when the option was given, and it is immaterial that the next day, he does the same thing again...

    Any advice appreciated, and Im a bit concerned that one day he did not start the second time...

    The laptop is only around the age of 6 months and otherwise runs great...

    Thank you

    Hello

    Recovery of the laptop back to factory settings.
    You use the Win 8 or Win 7 system?

    Usually, books Win 7 supports a HARD drive recovery by pressing F8-> fix my computer-> drive HARD recovery.

    If the same problem appears on the right after the system has been recovered, I guess there is a hardware problem and a technician must check the hardware parts.
