Satellite c855 - VGA port suddenly does not work

Hi people

I have the toshiba satellite-c855 - 17 c. Windows 7.
Usually, I work on my laptop and monitor, which I use by plugging the vga cable. I use this set to the top for more than a year and never had any problems.

Now, nothing happens when I plug in the cable. I checked with another laptop and the screen appears on the monitor - it seems that the problem is with my laptop.

Do you have any idea why this has happened and the solution to this problem?

Thank you
Ben.

Hello

What happens if you use key Fn + F4 (or just F4) video output?
You can move the monitor internal and external?

  • Satellite C855 - 1 HM-Touchpad does not work

    Hello

    My touchpad does not work! indications are he should be, pilot the newest, toggle F5 etc. Any ideas as to what may be wrong welcome. Machine is also only a few weeks, how do you contact technical support?

    Thank you

    Hello

    You can contact the Toshiba authorized service partner in your country, your hardware is defective.
    But you should first check if its hardware problem.

    First of all, you should check if the touchpad (pointing device) is enabled in the BIOS
    Press F2 during the powering of the device and go to the Advanced tab-> the system setup
    You will find the touchpad power option.

    If the touchpad is enabled in the BIOS, I recommend to check the touchpad system settings: Control Panel-> mouse-> last (Advanced) tab-> Advanced button

    Last but not least you should recover the laptop to test the device with factory settings.
    If all these tips would not be successful success, well, then I recommend to ask the guy to service

  • Satellite M45 - S351 - port PCMCIA does not work

    Help!

    I have a M45-S351. My PCMCIA slot is not working.
    When I go into Device Manager there are problems with the system Interrupt controller, SD slot & some unknown PCI device.
    Windows cannot locate the drivers.

    I downloaded all the drivers from the Toshiba web site.

    I always get these problems.
    I even did a restore of the entire system. Yet these problems come back. Does anyone have an idea what is the cause or how to fix?

    Thank you in advance!

    If you run recovery to reinstall Windows to its factory condition, and you have installed the latest version of the BIOS, then its likely to be a hardware problem. Maybe the Southbridge on the motherboard failed.

  • Satellite C855 - 1 GR - keyboard does not work properly

    Hello
    Yesterday I turned my laptop on to find I couldn't hit my password as some of the keys on the keyboard are not working. It's only a few keys, I noticed at the moment F L O R V, NumLock, enter, delete, and the arrow keys do not work either. When I press some keys turns num lock.

    Also when I open upward keys to self-retaining now is turned on, so I can't type anything, he used to come just I had turned off the laptop, but now it turns on if I just too closed.

    Any ideas? Ill use the keyboard of the screen now!

    Sounds like a malfunction of the keyboard.
    Try to connect an external USB keyboard and check if it will work properly.
    In case the USB keyboard would work properly, the internal keyboard needs to be replaced for sure.

  • Port forwarding does not work on EA6900

    Please help me to know what is the reason for this port forwarding does not work on my Linksys router:

    Model: EA6900 v1.1
    Firmware version: 1.1.42.161129

    I've set up two ports: TCP 22 and 8070 TCP to 192.168.1.10. (192.168.1.10 is up and running, I can reach the LAN ports).

    Yesterday, I had a live chat with Linksys support we tried to re - download the firmware even, but that did not help. Then factory reset and reconfigure the router did not help either.

    Unchecking "Filter anonymous Internet requests" and disable uPNP didn't help either (they have been suggested in similar topics).

    However, the IP displayed tab troubleshooting/Diagnostics reflect my external IP address (the IP displayed by http://whatismyip.com), which is weird, because I never have IP from my ISP from 100, that is displayed on the Diagnostics tab. So I guess it's a fake display or it relates to access to my router via www.linksyssamrtwifi.com ?

    Anyway I tried the two IPs from the outside, but the transfer simply doesn't work. (It works fine when I use my old router TP-Link).

    Please advise!

    Sorry guys, it seems indeed a double NAT problem. My ISP can detected MAC address change when I started using EA6900 (thinking that I couldn't not need public IP?) and since then he sends me IPs for NAT - ed. It is strange that the same day, he was working with my old router, but now it is even not working with my old router and not even working when I connect directly to my windows PC to my ISP (via PPPoE). I called their support line and they said that they will solve this problem within 72 hours. In any case, thanks for your help!

  • BlackBerry AutoText on Q5 Q5 suddenly does not work

    I have a problem on autotext @ my Q5. He is suddenly does not work. All the words that I recorded on my word substitution will not appear on my BBM. My OS: 10.1.0.4181.

    Can any body give a solution? Thank you

    No, my word substitution list is not empty, where is full. I already solved it by myself. It seems that we can only put Word Limited. So after that I deleted some of my word, inserts rerun. I think it is a bug for the Q5. Maybe we can only place max 80 words.

  • Port replicator does not work with Satellite P100-160 & Vista

    I just bought a Toshiba duplicator (part number: PX1173U-1PRP) but it does not work with the o/s Vista pre-installed on my P100-160. Can someone tell me where to find the Vista drivers for this device?

    It seems that the standard driver is not compatible with Vista and so you will need a new from the Toshiba page.
    You must remove the old driver and then install the new version.

    Good luck

  • Satellite A300-20 b - Touchpad does not work after BIOS update

    I've updated the BIOS on my Satellite A300-20 b latest version 2.00. Update succeeded, but when I rebooted system touchpad has stopped working.

    I tried to find the solution, resettled drivers (windows XP system). In the Windows Device Manager there is no problem with Synaptics PS/2 Port Touchpad, I see. Software Synaptics shows no problem I can enable and disable the touchpad, but it does not work for the touchpad. I tried Linux live CD and in this system does not work as good touchpad. I think there is problem in this version of the BIOS.

    Does anyone have the same problem?

    Hey Buddy,

    Have you tried to turn the touchpad on or off if you press FN + F9? Check this please!
    Also, try to load the default settings in the BIOS.

    What happens if you connect an external mouse to the laptop? It work?

    I can t imagine that the BIOS update causing this problem. If it doesn't work, you need to contact a service provider for help. They can check the touchpad and replace.

    Install the check and image recovery again if the situation is the same. If the problem persists contact your local dealer, explain the situation and ask for Exchange.

    Hello

    To be honest I n don't know 100% what your problem is.
    If you want to watch DVD movies on your computer with the help of a reader DVD Toshiba but the captain must be indicated on the external screen follow these steps:

    When you have connected the HDMI cable (other) outside on the screen, use FN + F5 and switch to the external display only. When you see the desktop on the beginning of the display external Toshiba DVD player and I think that everything should be OK.

  • Satellite C660-11W - Num pad does not work

    Hello!

    I have a Toshiba Satellite C660-11W, which I bought 10 months ago. Since October, the num of my laptop keypad does not work, but when I press the "Num Lock" button, it makes a noise as I had turned on the StickyKeys.
