Satellite P750-114 - booting up problems

I have a Toshiba P750-114 laptop that does not boot up from battery at all and will only boot from AC if it has been disconnected first and Ive depressed the power button for a few seconds to clear residual charge.
If I try to restart from sleep/hibernate or even shutdown but have left the power lead in from when it was previously running, I will only get the power on LED and the fan running, screen remains black.
If I remove the power, press the power button, plug AC adapter back in then press power button, it will boot up and run with no problems until it it shutdown again.
I tried powering up with a different tested battery and power supply but it apears to make no difference.
Ive read that the no display/fan & power working was a sign of motherboard failure so I had it checked over by a local laptop/PC repair shop (as the laptop is not in warranty) who found the touch panel ribbon was apparently causing a spark and that has been fixed, but they didnt find anything else and that fix hasnt actually changed anything with regards to booting the laptop up.
The laptop is running Windows 7 Home and has very few progams installed, but all software is geniune.
I'd really like to know what is causing the problem as although I can start it every time fine by following the shutdown-unplug-power on-plug in-power on routine, I want to find out if I'm just prolonging the inevitable collapse or is it ok/fixable?
Thanks all for any help you can give.

I think if the repair shop guy could not say exactly what causes this issue, I doubt that someone here in the forum would be able to provide an 100% right opinion about this issue.
It does not look like battery or AC adaptor issue.
Therefore another part seems to be affected. There are no many parts which could cause such issues: RAM or motherboard are mostly the parts which could cause such strange notebook problems.
P750 is not very old series, so warranty seems to be valid
I would recommend you to call the Toshiba authorized service center and explain exactly the issue. Maybe they could replicate this

  • WEb camera initializtion failed in Satellite P750-114

    Dear All,
    I am facing a problem with the web camera in my Toshiba Satellite P750-114. The laptop is less than two months old and the web camera was working fine, then it suddenly stopped working. The error message is "Web camera initialization failed. Please check your camera device and restart application or computer". The Microphone stopped working as well, as it is related to the web camera device. The operating system is Windows 7 64bits. It seems that the operating system is not seeing that there is a webcam anymore. I tried the following things:
    1- I uninstalled the web camera driver, downloaded the most recent driver from Toshiba website (the link is http://uk.computers.toshiba-europe.com/innovation/jsp/supportMyProduct.do?service=UK) , and installed it, but it did not work.
    2- I restored the original setting for the laptop, but still the web camera is not working.
    Two ways I am using to test the web camera: the Skype and "Web Camera Application" from Start/Toshiba/Utilities
    Please if someone has any idea on how to resolve this problem, the laptop is band new 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,
    Please help
    Bashar

    Generally speaking, after recovery image installation all hardware components should be recognized and installed properly so with this factory settings everything should work as on the day after you purchased your notebook and started it for the first time.
    If the cam doesn't work with factory settings I can imagine there is some hardware problem.
    I recommend you to contact nearest Toshiba service provider and ask for help. They can check cam functionality using their diagnostic tools and exchange cam if necessary.
    Of course it will be covered by valid warranty.

  • Satellite P750-114 - Display driver stopped responding

    Hi, i was playing a game called football manager and I suddenly recieved this message which took me back to the desktop.
    'display driver stopped respinding and has recovered' 'Display driver NVIDIA Windows Kernal Mode Driver, Version 2.67.44 stopped responding and has successfully recovered'
    Any idea what this is and how it can be solved? I have recived this number of times whilst playing. could this mean the laptops faulty? thanks

    Hi naz90uk,
    I wouldnt recommend installing the nVidia display drivers because they are not pretested on your notebook. That means your notebook could overheat and damage the hardware.
    Even you have the newest Toshiba display driver I would try reinstalling it. At first remove the old display driver (control panel > uninstall a program) then restart your computer. Run a registry cleaner like CCleaner (Freeware) and remove old registry keys. Restart the unit again and now install the newest Toshiba display driver.
    Check this!!!

  • Win7 install with multiple/all the FAILS! Satellite P750 (PART NO. PSAY3A-02T001)

    Laptop: Toshiba Satellite P750 (PART NO. PSAY3A-02T001)
    Installing: Windows 7 Home Premium SP1 (64 bit)
    Background: Laptop is around 2-3 years old now. Formatting and installing a fresh copy of Win7. Doing this for a close friend.
    Issue #1: Using the "Windows 7 USB DVD Download Tool" off the microsoft website, I attemped to install Win7 via USB drive (had so many issues before using this tool ). It boots to USB perfectly and starting going through the installation options. When it gets to "Where do you want to install Windows?"  (creating and seleting HDD partitions) I hit a major road-block!
    p.s. USB in USB2.0 as I originally tried 3.0 and coudln't even make it that far....
    I get the Error "Setup was unable to create a new system partition or locate an existing systm partition. See the Setup log files for more information." Basically the Primary disk is created but the system disk wont.
    p.s. The HDD still does show up and worked before this all. it's not a failed HDD.
    I've tried (most of these were "Fixes" I found on forums that never worked):
    1. Creating different size partitions, multiple partitions, leaving GB's of "Unallocated Space" hoping it will create a system partition. Didn't work.....
    2. Formating the whole HDD using Command-line and wiping it completely clean. Honestly, this was stupid because now I cannot even go back! Didn't work.....
    3.Changing BIOS settings and praying it will work. Most of the BIOS settings these fixes told me to change, aren't actaully on this Toshiba model. I even restart to default settings. Didn't work....
    4. Even tried a "load Drivers" fix I found. The fix asked for a SATA driver, but I got every driver just incase. Not a single driver even appeared on the "Select the driver to be installed" screen. Unticked the "hide drivers.." box also... So that didn't work either...
    At this point I was pretty mad so I went and purcahsed some DVD-RW's to burn the ISO onto and try that instead.
    Issue #2: Using the same tool as before, I installed Win7 onto a DVD. I then ran the DVD on my PC to test and the setup.exe showed up. I then put the DVD in the Toshiba laptop and using F12 to select "ODD        TSSTcorp CDDVDw TS-L633F" (the other options were "HDD/SSD, USB and LAN).
    p.s. The DVD drive lights up and I can hear it reading the disc (normal slight humm).
    I then get:
    "Intel UNDI, PXE-2.1 (build 083)

    Reboot and Select proper Boot device
    or Insert Boot Media in selected Boot Device and Press a key_"
    To me, this is the LAN controller boot, but it didn't even read the disk.
    I've tried (and again, most of these were "Fixes" I found on forums that never worked):
    1. Changing Boot priorities and settings. I even tried to disable LAN boot in BIOS (but you cannot on this model). Didn't work..
    2. Yelling at it and holding myself back from hitting it with a hammer. Still attempting..
    3. Praying to a higher power. Didn't work...
    Ideas I have left that may work:
    1. Downloading and burning a different ISO. maybe even trying 32bit. (was 64bit before starting)
    2. Waiting for someone much smarter than me to reply on this post and help me!
    3. Telling my friend that "It's not my problem, while I run off into the sunset!"
    PLEASE SOMEONE HELP! This is doing my head in!
    and yes, I've tried turning it off and on again 

    oh my **bleep**ing god...... I am so mad right now! 95% butthurt infact!
    MY RAGE IS STRONG!
    Just found out off the owner that the DVD drive doesn't work.. 
    SO! The DVD drive doesn't work and it seems like the only way to install Win7. I have a feeling that this model doesn't do USB very well....
    will an external DVD drive work for this? or some I find someone with a toshiba that has the same model dvd drive inside and swap them for an hour while I do it...
    or should I try LAN... havn't one LAN install in a home environment before..

  • Satellite P750/P755 - Back Up And Restore Windows 7

    Hi,
    My harddrive is about to fail on my Windows 7 Satellite P750; I have been getting warnings of an impending failure for a month now. I have purchased a new harddrive and it is ready to go, however I am unable to create a backup and restore point. I am getting an error 0x81000037: "Shadow files cannot be read".
    Let me give you some of the history of my machine before getting to the issue. Windows 7 came preinstalled on this machine. About a year ago I created a new partition and installed Linux. Linux then took over the boot responsibilities. A couple of weeks ago I deleted the Linux partition. This gave me a problem as the computer was unable to boot. Fortunately I had recently created a back up and restore point, and during the process I was asked if I wanted to create a Windows 7 Home Premium Repair Disc. I was able to use this CD to access a command line tool which made the machine bootable again.
    However, I no longer have a hidden boot partition on my machine (at least according to the Disk Management snap-in I don't). I am now getting the above error when I attempt to create a new backup and restore point. I no longer have a copy of the previous back up and restore point (I deleted it to make room for a new one).
    From my research, apparently one of the possible causes of the error 0x81000037 is related to the hidden boot partition size. Since i do not have the hidden boot partition I fear that this could be the cause.
    There are other possible reasons for this error. For example a virus which anti-virus refuses to allow access to during the back up and restore partition, and junction points in the drives to be backed up which are mounted volumes. I have run a full scan on my computer and cannot find any threats. I have checked my junction points (of which there are a few) and none are mounted drives.
    This leads me to suspect that the lack of a boot partition is the problem. I have seen some people in forums suggest that it is best to back up all my data in the traditional manner (already done, since you ask), install the new harddrive and then install Windows 7 again.
    So finally, we get to my question!
    As Windows 7 came installed on my machine, I believe that I do not have the disks to reinstall it on a new harddrive. Is this correct? Am I able to obtain a copy?
    To be honest I wouldn't mind reinstalling Windows on a new harddrive, rather than using a back up and restore point. I have a LOT of programs and rubbish which have accumulated in this one over the last (almost) 3 years.
    Thanks for your patience. If there are some specifics which would be helpful, but which I have left out (I am sure there are) please let me know.

    >As Windows 7 came installed on my machine, I believe that I do not have the disks to reinstall it on a new harddrive. Is this correct? Am I able to obtain a copy?
    You did not get any disks because Toshiba provides own recovery disk creator software which is always preinstalled on the new notebooks.
    This recovery disk or media creator tool creates Recovery disk which can be used to recover the notebook.
    It was a big mistake not to create such disk however, you have a possibility to order such disk here:

  • Satellite A300-114 - Won't reinitate after screen shuts down

    Hello.
    I have a Toshiba Satellite A300-114 running with Windows Vista Home Premium.
    It was working fine until two weeks ago, now, after some time of inactivity, the screen shuts down and it won't turn on agian. The Hard drive light blips but the Screen stays black. This is becoming more often.
    Does anybody have any ideia what the problem is?
    Thanks :)

    Sorry, I'll try to write with a more correct english.
    My problem was, when I leave my laptop alone, the display shutts off, the hard drive light under the touchpad keeps bleeping, but what ever I do the system doesn't "come back". I have to hard boot the computer.
    Now, i've tried with different power settings, and the same happens, and I also found out that when i have the "Turn off the display" set for never, the computer also starts working after leaving it alone for a while.
    I'm also not able to shut down the computer, I get the blue screen and the message "Closing" and nothing happens

  • Satellite P750: Unable to install Bluetooth Stack driver on Windows 7 (x64)

    Hello.
    I own a *Satellite P750-02T* (Part no. *PSAY3A-02T001*).
    In the order what I did:
    1) I formatted its HDD and reinstalled OS to *Windows 7 x64 Ultimate SP1*.
    Then I downloaded *ONLY BIOS and the drivers* from [its Downloads page|http://www.mytoshiba.com.au/support/computers/satellite/p750/psay3a-02t001/download?os=25] :
    2) I updated its BIOS to *v1.90* (the laptop came with v1.80)
    3) I installed all the drivers:
    - both LAN and WiFi
    - Intel Chipset (latest available)
    - all video drivers (Intel HD Graphics, NVIDIA Graphics, and Intel HDMI)
    - Card Reader
    - Realtek HD Audio (latest)
    - Synaptics Touchpad
    - USB3.0
    - IR
    - TV-Tuner
    However, I'm *unable to install the Bluetooth driver (v8.00.06(T)* )...
    When I run setup from the [above-mentioned page|http://www.mytoshiba.com.au/support/computers/satellite/p750/psay3a-02t001/download?os=25] it partially detects *'Bluetooth USB Controller-10 from TOSHIBA'* (USB\VID_0930&PID_0215&REV_001)
    and then installation simply freezes displaying +'Installing the Bluetooth Driver. Please wait+.' and stays like that forever...
    I also tried downloading a driver from [another location|http://aps2.toshiba-tro.de/bluetooth/index.php?page=download-toshiba] for TOSHIBA notebooks - v8.00.02(T):
    and followed installation instructions displayed under 'Details'
    but there was the same outcome - the setup simply freezes...
    Installing Hotfix (*KB978258*) recommended there didn't work either - the message '+The update is not applicable to your computer+' pops up.
    And I understand why - this Hotfix is [already included|http://download.microsoft.com/download/E/B/A/EBA55FE2-373A-4351-9346-6D762B79AA69/Updates%20in%20Win7%20and%20WS08R2%20SP1.xls] into Service Pack 1 for MS Windows 7.
    I spent hours searching on the Internet for a solution. Although there were some similar cases none of the recommendations actually worked. I tried installing:
    - WiFi driver before installing Bluetooth (someone suggested that those two are the parts of the same card);
    - resuming installation in Safe Mode;
    - *Toshiba Value Added Package* hoping those tools somehow will kick in.
    Nothing worked...
    It's interesting that when for the sake of experiment I tried to run installation for my generic Bluetooth adapter (using the driver [for non-TOSHIBA notebooks|http://aps2.toshiba-tro.de/bluetooth/index.php?page=download]) then everything run smoothly!
    *Using Bluetooth connection on this laptop is very crucial for me.*
    I hope I shall not have to return this wonderful notebook as I know TOSHIBA is one of the best manufactures and am sure there is a solution to this problem.
    Thank you very much.
    Evgeny.

  • Windows thinking Ctrl key is stuck on Satellite P750

    Yes, I've done some thorough googling and searching of this forum before posting.  No prior topic quite resembles my problem; and the solutions don't help.  Sticky keys box in the Control Panel is unchecked, not using any aides--the computer is brand new with barely anything installed and zero customization.
    Using my Satellite P750 (purchased just in October 2011), every once in a while after simply using Firefox or Chrome (either one)--using nothing but the mouse pad and the left mouse button--the size of the font of the text in the browser randomly increases, and after that the computer starts thinking the Ctrl key is being held down.  (Ctrl +Alt + Del does nothing, only rebooting the machine).  I realize that I'm inadvertently toggling some function, but what?  Looking around Control Panel, nothing seems to be close to "if user moves curser, increase font size and make the Ctrl key stuck".
    Any ideas would be greatly appreciated.
    Solved!
    Go to Solution.

    Thanks, had the same problem with brand new Toshiba Laptop.
    Ours also had external mouse attached. With OS thinking CTRL key stuck, Excel went ape and began doing all manner of evil upon a very complex spreadsheet we were working on.
    One note: On ours after getting to Mouse Properties, there was not an 'advance' option. Instead we had to select:

  • Satellite P750 - Shutdown issue after removal of external monitor USB 3 hub

    Have operated my Satellite P750 laptop with external DeII monitor for a year or more now.
    Monitor has a Usb 3 hub. (i have some ext HDD plugged into these. So far no issues. I unplugged the monitor usb hub from laptop (to create wndows image backup straight through the sole usb3 port on laptop.
    After this finished i found that i was unable to shutdown or restart laptop. It gets to the light blue 'shutting down' screen; HDD light flashes for 5/10 secs then it stops accessing disk with power still on and stuck at blue shutdown screen; laptop even sounds like it shuts down.
    Two things, i can hold down power button till hard stop, then press again to restart, and all is fine; no error messages when win 7 start up again. Or i have once just left it sitting without holding power button- it seemed to be like this for about 4 hours (monitor went to standby cause idle) before powers down.. When i start laptop after this i get windows warning failed to shut down properly.
    It took me a while to work out which device was causing the issue; but can now replicate any time.
    So - unplug monitor usb hub from laptop; laptop fails to shut down/restart.
    Replug DeII usb hub back to laptop; no problem laptop back to normal shut down.
    Any ideas??? (this means whenever i go portable with laptop i have to hard shut down/ hold power key to turn it off????)

    To be honest I dont know why the system cannot shut down properly without connected USB monitor hub but system shut down issues are mostly related to some processes which are running in the background.
    Sometimes such processes are locked and could not be closed due to different reasons. This may prevent the system from shut down
    Maybe this is the case
    Try to clean the system as well as the registry using CCleaner (its freeware tool).
    You should also check what processes are running in the background maybe one of this processes is related to the hub which cause your shut down problem

  • Satellite L30-114 - Need driver for sound and SM bus controller

    Hi, friends
    Plz I need your help on my Satellite L30-114. Am having problems with the sound and the SM bus controller, even I have downloaded the sound driver and install it, from my device manager sound is not sick, it always telling me my device is working properly? Plz i need help on that.
    Secondly my SM bus controller is sick it has the cormer sign plz how can I rectify it, even my wireless is working fine.
    Only the sound and sm bus controller is giving problems.
    Thanks will be waiting for your replies.
    newton

    Hi
    To be honest I doubt that you have installed all files from the Toshiba website. Normally the Toshiba website contains all drivers and tools that you need to restore factory settings after this there are no more yellow exclamation marks or unknown devices in device manager.
    By the way: What installation order you have used?
    On the Toshiba website you can find the installation instructions document. This is a list for the recommended driver installation order.
    Check this!!!

  • I can't log onto-into my Satellite P750 Win 7 profile

    My laptop is a SATELLITE P750 with Windows 7. I started it today and it loaded windows fine, up to point where it requests my profile password.
    I have not changed this in years and know it is correct but i keep getting the message 'The User Profile Service service failed the logon. User profile cannot be loaded'.
    I do not have any backups made :( silly me.
    Any ideas how to get past this as I can't get on my Laptop.
    ps I would rather not have to re-install windows or anything too major
    Thanx Chris

    Hello, I have, since asking this question, found the answer through windows.microsoft.com
    If you ever have the same problem, google the message 'The User Profile Service service failed the logon. User profile cannot be loaded' and follow link to support.microsoft where they give you three options to fix. I used the 1st method using regedit and changed the s-1-5 files in the profile list as explained.
    This fix worked perfic
    May all you IT troubles dissolve away like mine.

  • Satellite P750 - Wireless card is not working

    PSAY3A-02q001. Laptop is about 20 months old. Turned it on this afternoon and the wireless is not working. Atheros AR9002WB-1NG. Cannot b switched on and off from the hardware switch. The switch beeps when pushed. Network troubleshooter indicates card is not turned on. Card is still detected in windows.
    I am feeling that this indicates the card has failed. Any thoughts?
    cheers Simon

    Ok just to tidy this up
    The Atheros OEM wireless lan and the bluetooth were both working.
    They stopped but I could still see the card in device manager.
    Thinking the card was faulty and wanting to upgrade to a better wireless card I purchased an Intel 6235. i had the same problem i.e. the card would not turn on. I reinstalled the Toshiba value added package which then returned functionality to the hotkeys to turn the wireless on and off.
    Next problem i was unable to get the bluetooth on the intel card to work.
    There is a long thread on this on the intel community forum with the bottom line being a lot of people can't get it to work on their laptops.
    I removed the intel card and reinstalled the OEM atheros card which is now working except i can't get the bluetooth to function correctly.
    The intel bluetooth software is virtually uninstallable.
    This is also covered in the same community forum.
    The next step will be reinstalling the OS (windows 7 x64). It has been running for 2 years so is probably due.
    Learnings.
    1> If your wireless card stops working in the P750 and you can't turn it on reinstall the Toshiba Value added package.
    2> Don't install an Intel Centrino 6235 wireless card in your Satellite P750. The bluetooth will not work.
    3> Don't install the Intel Proset bluetooth software on your Satellite P750. It wraps itself around everything and can't be uninstalled. Actually you can get it out manually

  • Does Satellite P750-10E supports keyboard backlight?

    Hello,
    Yesterday I bought Toshiba Satellite P750-10E and I'm not sure if this model has keyboard backlit, because in few reviews I saw that this model has keyboard backlit but I dont have it, or dont know to turn it on.
    Please help me to fix this problem, I really need keyboard backlit because many times type in dark room. :)
    BTW this is awsome notebook, Im very greatfull and happy to have this model, just need a keyboard backlit if its possible to turn on.
    Thank you for answers. :)

    Hi
    Checked the user manual of the P750-10E but didnt find the info that the keyboard backlight would be available I think the notebook does not support this feature.
    Furthermore if the keyboard would support backlight, then the Z button should contain a tiny sign which would refer to this feature.

  • Satellite P750-10R - BSOD while gaming - wrong graphic card?

    I've been having trouble with this laptop since I got it. I've hardly been able to play any games on it even though it surpasses even the recommended specifications. Sometimes it will freeze, other times it will BlueScreen.
    I've taken in to the shop three times, the last just two weeks ago, and it hasn't changed. Today I was comparing the specs and I noticed this on the Toshiba products specs:

    I really am hoping I'm misunderstanding something here. Do these match up?

    Hi,
    Can I add a question to this thread please? I have a Satellite P750-13M and have had it for over a year and a half. Mainly I use it for work and some low intensity games, but recently I started using it for more graphic intensive games. Often the computer overheats and crashes when doing so. While investigating the problem I came across the same NVIDIA screen shot that wertxi posted. According to the NVIDIA control panel I only have 64MB of dedicate VRAM, but the P750-13M specs page ...
    http://www.toshiba.ie/discontinued-products/satellite-p750-13m/
    ... says that I should have 1GB of dedicated VRAM. Is this a discrepancy or am I not comparing like with like?
    I haven't been having any blue screening, just over heating and slow graphics rendering, although the machine (supposedly!) exceeds the recommended requirements for the game.
    Thanks,
    Simon
    EDIT - Just to clarify, in case I rambled too much, I do have both display adapters listed in device manager and both are up to date. My query is about the discrepancy in the dedicated VRAM indicated in the product specs and in the NVIDIA control panel.
    Thanks again

  • Satellite P750 - Stops resonding after waking from hibernate mode

    Can any one help, I recenty bought a Satellite P750 with an i7 processor it has 4GB RAM. I have been experencing problems since buying it. It just seems to stop responding the round icon is spinning showing its thinking but I can wait for 10-15minutes and there is no change. This problem occurs sporaticly and some times occurs when loading up new programs.The problem occurs nearly all the time if it has entered hybernation and when I awaken it with mouse it starts up but when I to connect to the net for example it will bring up the internet explorer page and the round icon will be spinning and it will stay like this for ages until I am forced to shut it down with the on and off button. When I have this problem I have tryed using CTRL ALT DEL to open up task manager but task manager will not respond.
    Has anyone had the same problem and is there a solution. Note when I turn of the HDD protection mode the probem seems to happen less frequenty but still occurs.

    Very interesting Did you check your HDD for some errors?
    I would recommend doing this. Try the tool called Drive Fitness Test. You can google in order to download this... its freeware so you can use it for free.
    I think its good idea to check the HDD because faulty HDD could cause such issues too.
    By the way; did you try to reinstall the OS again and to check if this issue would be fixed then? HDD recovery could be useful. It sets the notebook back to factory settings.
    I think its worth a check.
