Why does my hp probook 6540b not displaying when i insert the hard drive?

Display problem when hard disk is inserted

Hello amir642
Thanks for posting on the HP Forums!
I understand you are experiencing an issue with your notebook. However, since this is a commercial notebook, you should post your issue on the notebook board of the HP Enterprise Forums for a better answer.
Have a wonderful day!

  • Why is it that my powerbook does not recognize when i insert external hard drives through the USB 2.0 port

    when i insert an external harddrive through the usb port, my mac doesnot recognise that its even there but when a flash disk is inserted, it recognises it perfectly.
    why does that happen?

    Michael is on the right track. Some external hard drives lacking their own power supply simply cannot get enough power from a single USB port. It is most noticeable in the "name brand" drive that the office supply and computer superstores put on sale every other week. Their chipsets seem to be better optimized for Windows than Macs.
    Flash drives work because the don't have a power-hugry motor that must turn.
    There are two easy and inexpensive cures that allow you to keep your current drive:
    get a "Y-cable" that let you connect one drive to two of the computers UWB ports. Example:1 Meter USB 2.0 A to 5 Pin Mini B Cable - Auxiliary USB "Y" Power Design for external hard drives.
    get a self-powered USB hub. It has a separate power supply that boosts what goes to the drive. Example: Macally TriHub - 4 Port Hi-Speed USB 2.0 Hub for Mac & PC
    If you need the computer and drive to work together in an environment lacking a power source for the hub, and the y-cable isn't an option because you have too few available USB ports, then your only option is to replace the current drive with one better optimized for Macs, like these:

    This particular one has the option of running on power from the computer's USB ports or, with an optional power supply, wall power. A good compromise for both remote and desktop use.

  • HT3887 why does my iPhone say device not supported when connecting to my make even after it has successfully paired?

    why does my iphone say device not supported when connecting to my mac pro, even though it has already succesfuly paired? I also use a wirless bluetooth keyboard and mouse on the computer successfully.
    Also when I turn Bluetooth on on the phone the devices cog never stops turning (forever serching for a device)

    iTunes automatically syncs voice memos to your iTunes library when you connect iPhone to your computer.
    It couldn't be much easier than that as you don't actually have to do anything more than normal.
    This lets you listen to voice memos on your computer and provides a backup if you delete them from iPhone.
    Voice memos are synced to the Voice Memos playlist. iTunes creates the playlist if it doesn’t exist. When you sync voice memos to iTunes, they remain in the Voice Memos application until you delete them. If you delete a voice memo on iPhone, it isn’t deleted from the Voice Memos playlist in iTunes. However, if you delete a voice memo from iTunes, it is deleted from iPhone the next time you sync with iTunes.
    USB syncing is far faster than Bluetooth.

  • Why does my form data gets cleared out when clicking on the back button.

    Can someone explain why does my form selections get cleared out when clicking on the back button.
    I have a JSP page that displays a form with some selections and text boxes. I populate the page and submit the request. The action on the submit call another jsp page, which processes the data and displays the results via a <jsp:include> statement which calls the results page. When clicking on the back button from the results page, it returns me to the form page, but the selections are cleared out.
    1. Is there something in my calling of the pages that causes this behavior and can I prevent it?
    I notice that the behavior is different when using the IE 6.0 version Netscape 7.1. IE clears the page Netscape 7.1 retains the settings.
    If I cannot prevent this behavior does that mean I will have to save the state of the form data. And if I have to save the form data, what would be the easiest method of doing this. I'm a beginner to JSP and Java, but have some ASP experience. I don't understand why the back button in a JSP request clears the form data but a regular HTML page does not can someone explain?
    THANKS.

    the browser doesn't have to remember what you submitted and fill that back in.
    you can't prevent it unless you can ensure a new request to the server in which you can fill the default values in there.

  • Why does my iMac (with Mountain Lion) no longer recognize my external hard drive I have used as a back up via Time Machine after the hard drive was accidentally unplugged?

    Why does my iMac (with Mountain Lion) no longer recognize my external hard drive I have used as a back up via Time Machine after the hard drive was accidentally unplugged?

    Do you mean the external hard drive is not mounted on the iMac desktop?
    Check if Disk Utility sees the drive. Applications / Utilities / Disk Utility. If the external shows up in the left column, select it and click on Mount.
    If it does show up this way, I recommend using DU to Repair Disk.

    Hi i am have had a lot of trouble emptying my trash. when i go to put something in there it asks from my password and the item goes off the screen, but this does not clear any space on the hard drive.

    1. Triple-click the line below to select it:
    ~/.Trash
    2. Right-click or control-click the highlighted line and select
    Services ▹ Show Info
    from the contextual menu. An Info dialog should open.
    3. The dialog should show "You can read and write" in the Sharing & Permissions section. If that's not what it shows, click the padlock icon in the lower right corner of the window and enter your password when prompted. Use the plus- and minus-sign buttons to give yourself Read & Write access and "everyone" No Access. Delete any other entries in the access list.
    4. In the General section, uncheck the box marked Locked if it's checked.
    5. From the action menu (gear icon) at the bottom of the dialog, select Apply to enclosed items and confirm.
    6. Close the Info window and test.

  • I have an Ipad, I activated the time capsule with no issues. I added the airport Utility application without issue.  However, I do not know how to access the hard drive with either my Windows computer or the Ipad.  Does someone know how?

    I have an Ipad, I activated the time capsule with no issues. I added the airport Utility application without issue.  However, I do not know how to access the hard drive with either my Windows computer or the Ipad.  Does someone know how?

    On windows load the airport utility .. latest correct version as possible.. there is no windows 8 but win7 works after a fashion.
    Make sure the TC is using SMB compatible names.. short no spaces and pure alphanumeric.
    Type the name directly into windows explorer.
    \\TCname or \\TCIPaddress
    If no luck turn off all the firewalls.. internal windows plus security software plus whatever other gargyoles and other rubbish AV software you have running.
    Ensure windows is able to at least ping the TC by IP address and name..
    Use the utility in windows to set file sharing to guest account on with full read and write access.. and set workgroup to WORKGROUP.

  • Imac won't start, not sure if it is the hard drive

    My computer wont start now. It was taking ages to start up and now it wont at all. It was suggested on this forum that the hard drive was knackered. I pressed squiggle button + R, and then copied the disk to an external hard drive. I then re-started in the same way, and chose the USB external hard drive as the starty up disk. The computer still wont start. I am thinking that if it wont start this way then probably the internal disk is ok.
    I was going to try an reinstall the operating system, but I dont appear to have any disks.
    Does anyone know what the next logical step  might be?
    I can't really take it to a shop to be fixed due to access / logistics.

    Your test is not conclusive because if the system was damaged, copying it to another drive would not fix it. It would still be damaged and unbootable.
    You can reinstall the OS by booting from the Recovery Drive the Mavericks installer created on your hard driver as part of the initial installation. Boot your computer while holding down Command+R to boot directly into the Recovery drive. You will need a broadband internet connection to download the Mavericks installer.
    However, before you reinstall the OS while you booted into the Recovery Drive launch Disk Utility and run Disk Repair to be sure the volume structure of your hard drive is sound. If it is damaged and Disk Utility is unable to effect repairs, you will have to erase the HD. In that case I would not place any reliance on the hard drive or any data on the drive regardless of the S.M.A.R.T. values.

  • I have a disconnect between my external hard drive and lightroom 5.6.  The recommended steps do not connect 11000 photos on the hard drive.  How can I connect?  I am concerned I have lost my edits in lightroom.

    I have a disconnect between my external hard drive and lightroom 5.6.  The recommended steps do not connect 11000 photos on the hard drive.  How can I connect?  I am concerned I have lost my edits in lightroom.

    after some sorting out your article, I clicked on a question mark with the message find the missing folder.  This brought me to a page where I could choose a folder by year and click on it.  The question marks disappeared and the photos were available.  In some cases I had to click on the year folder for each subfolder by date.
    The find missing folders message did not bring me to the finder window in which I could click on folders in the hard drive itself.  I appreciate your help big time!!

    Yes, if you do a fresh install of the operating system, it's like a brand new machine.
    No, if you restore from a backup like a bootable clone or TimeMachine drive.

  • HT201250 The back ups are not displaying when i enter the time machine

    I'm trying to restore my files to my new MacBook I just purchased. I have the external hard drive connected and entered the Time Machine. But, the back-ups are not displayed "in pink on the right side" as indicated in the directions. I do see the back up folders when I open up the hard drive using Finder.  Any ideas on how I can restore my files?
    Thanks
