I have my MBP connected to a thunderbolt, power of the connection screen and using the ethernet on love at first sight port to connect to my router.

These two functions has stopped working. The USB ports still work and the works of the display, but stopped power and ethernet. Is there a way to re - configure or troubleshoot this?

You can unplug the TBD from the wall, wait 3 minutes and reconnect.  Who can help.

    Some say that you could restore the BIOS using factory default values with this. Here is a document that shows you how to restore the default BIOS settings. In this way, it will look at the hardware installed on your laptop.

    You can try to use theWindows Update Troubleshooter to fix updates that do not come through Windows.  Please restart the laptop twice to make sure that all updates are completed!

  • I own CS2, and my machine stop working. The replacement machine has no optical drive.

    I can't be able to raise this issue with the Adobe customer service.

    It's an endless loop of referrals in the FAQ and forums, with no way to send an email to them?

    Am I missing something?

    It seems they should be able to put up a download or something if I can actually USE their program, I spent $500 on, on the new machine mjy.

    Frustrating.

    Yes, you must download a new version of no activation of photoshop cs2 to replace your old one and use the serial number on the page with downloads of cs2.

  • Keyboard and mouse stop working at the login screen, but work very well before he gets to connect.

    My keyboard and mouse suddenly stopped working today, I was pressing F11 to try to get the system to boot from a recovery screen and it wouldn't, but when he returned to my screen connection and requested my password it won't let me not use the mouse or the keyboard, I wonder if I accidentally turned off something and if anyone knows how to turn it on turn it back on.

    Hello Djc618,

    Thank you for your message.  You have a friend or a family member that can allow you to use a keyboard to see if the material can be defective?  You can also try using your keyboard on another computer, if this does not work then you probably have a bad keyboard.
    We can't wait to hear back on your part.
    See you soon

    1. have you made a recent software or hardware changes to the system?

    You can check if there is information in Event Viewer which may help us to solve the problem:

    What are the information contained in the logs of the event (Event Viewer)?

  • Digital Persona software stops working on the Pavilion dv8-1250ea

    Hello!

    I noticed that Digital Persona, the software for the JJUJ scanner integrated on my HP Pavilion dv8-1250ea stops working whenever the laptop wakes from standby or hybernation mode. On the login screen, the icon on the right referring to the fingerprint reader warning flashing at a rate of about twice a second and the following note says "fingerprint reader not detected". So I'll type the password manually, but the cursor in the field password prevents jump at the beginning of the field at the same pace, and it seems as if there is a current discount. The only way to log is press the 'end' key immediately before each character in the password, which is a disappointment.

    I recently downloaded an update for Digital Persona, but it has not solved the problem.

    Any ideas how to fix? Thanks in advance!

    Here is a work around, see if it works... You will need to go to Device Manager, depending on what hardware you have; AuthenTec orvalidity... Double-click on it... who will launch the Properties Windows... Click on tab power management... this tab, uncheck the box that reads "allow the computer to turn off the device to save power"... and see if it works... ' "

  • Links for Smartphones blackBerry stopped working in the browser

    Yesterday, the links Hypertext has stopped working in the Blackberry browser.  In other words, when I click on a link, it highlights, but it won't pick up the page a hyperlink.  It does not display a status of "loading" at the bottom of the screen.

    The screen click on works fine in other applications.  The screen click on works fine in the browser when you use the menus.  It works simply when you click a hyperlink on a web page.

    It was all working fine until I did a Facebook mobile Web page.  This isn't Facebook mobile app, but the mobile Web site read using the Blackberry browser.  I went through the Facebook mobile site on the Blackberry browser several times, and then the links stopped working and no longer works for any Web site.

    I checked the settings and checked and checked and can't seem to find a solution.

    I deleted all the cache of the browser.

    I have not changed the browser settings.

    Does anyone have a solution?

    Hi and welcome to the Forums!

    Whenever random strange behaviors creep, the best thing to do is a battery pop reboot. With power ON, remove the hood back and remove the battery. Wait a minute, then replace the battery and cover. Power on and wait patiently through the long reboot - about 5 minutes. See if things return to functioning. Like all computing devices, this one suffers memory leaks and other... with a hard reboot is the best remedy. Some have taken to do this on a recurring basis as a preventive measure.

    Best!

  • USB mouse and keyboard suddenly stopped working

    My USB connected Microsoft USB Bluetooth mouse and keyboard suddenly stopped working today. After researching everything I could, I didall that I could find as a possible solution that has been:

    • Update of the chipsets
    • Uninstalling usb in Device Manager and reboot devices
    • Updated via Device Manager, usb devices
    • Reformatting and reinstalling Windows 7
    • Stop, unplug and allow the card mother "reset".
    • Try multiple ports
    • There is no 'connect' button on my mouse so I can not sure try this
    • Replace the batteries in my mouse
    • Obviously both devices have been connected
    • Updated the software for the mouse

    I have tried literally everything I could think of or read previously and I am out of options. Oddly enough however, after reformatting and reinstalling windows, my USB storage device is found and is working, but the keyboard and mouse are not. Please don't bother not suggest anything I listed above, I obviously already tried and found no chance.

    Update
    I have solved my problem. For later use, if anyone has this problem and no other solution seems not work; That's what I did.

    I bought a USB 2 ports PCI card and installed in my computer, then go back to Windows XP. While my original front and rear USB ports still recognize a flash drive, they do not recognize the keyboard or USB mouse, make ports PCI card. I had also updated ALL the updates of windows on the site, not the auto update available on the desktop. Although I don't know the cause, I am certain that somewhere, something was is altered by the hardware or software, and my default USB ports do not recognize mouse or keyboards.

    Another piece of knowledge in case anyone is interested; I use a card mother gigabyte s-series and my nvidia video card GeForce previously is no longer recognized in the port, it would cause my computer go into a State of hibernation and the monitor would go into "Analog Power Saving Mode". The only solution was to spend a friend with my video card. (Its graphics card is a GeForce 9800 GTX, mine was a GeForce 9800 GT. No reason why it should make a difference.) According to me, even if my computer is less than two years old, I was sold a bad mother. I read online cases in other forums for technical support of people having the same problem. Gigabyte motherboards stop random ports for no known reason.

  • How to get help with Add ons and extensions that stop working

    I have saved passwords and it has stopped working. It's so hard to get help with Moxilla

    rosemarybales said

    I still don't know why the extension button passwords saved with the key icon has stopped working.

    This button displays the saved passwords in Firefox's built-in password manager, is no separate passwords that record you in Dashlane. Can you save passwords in both places? (Well, I guess you do.)

    I have a guess on why it has stopped working. Firefox 40 has some changes to how extensions can work with the user interface, so quite a few extensions that have been more than one year must be updated for Firefox 40. It has been updated on January 10, 2012.

    Anyway, the way of 'long' to display the passwords saved in Firefox is through the Options page, the Security Panel, the saved passwords button.

  • Firefox extension: 'TrueSuite 5.2.500.16' stopped working after the last update of firefox (30.0), although subject: said plugin activated. No difficulty to make it work?

    Firefox extension: 'TrueSuite 5.2.500.16' stopped working after the last update of firefox (30.0), although subject: said plugin activated.

    I tried to reset firefox and search for similar problems, unfortunately found nothing.

    It is also weird empty space before the address in the address bar

    other extensions and addons seems to work very well.

    Firefox 30 spent some less commonly used "Always turned on" plugins "asking to activate. To check and change this to TrueSuite, you can use the page modules. Either:

    • CTRL + SHIFT + a
    • "3-bar" menu button (or tools) > Add-ons

    In the left column, click on Plugins. Then on the right, check the setting on the right side of TrueSuite.

    Any difference?

    Note to other readers: the original poster had to leave Firefox and start it again until it is actually entered into force.

  • HP ENVY laptop - 15-ae178ca: Second monitor stopped working after the automatic update of HP

    I use my laptop with a second monitor (HP Pavillion 22xw) connected by HDMI. It was working fine until yesterday (including yesterday it worked), when a message from automatic upgrade HP was shown to informing him that the system needs to be restarted. After that, my second monitor stopped working. The system will not identify it more. I tried another cable, I rebooted several times, I tried to update the specific Intel graphics driver, I tried to uninstall and install manually another (I can't get this one done, because when I run manually downloaded driver there is a message saying that I need to contact the manufacturer). Please notify that I need my second monitor is fully functional!
