HP dv7-7334ea Envy a lot of questions

So I bought my Hp Envy dv7-334ea about 6 weeks ago and it ran allright until recently where I have just been noticicing problem after problem. Help would be greatly apprecaited on any one of the following:

-The devices do not work: my Hp truvison HD webcam does not work and is not there in Device Manager and the same thing with my fingerprint on the portable reader, the cannot be found and it's almost as if though my laptop never had them first because there is not a trace in the Device Manager.

-One of the usb ports does not work. It was bugs me for a while - my laptop has 4 usb ports, 3 work fine, but one of them won't do anything

Doppping - conntection wifi problems: this is more noticeable on Skype as the call happen sometimes and my laptop will lose connection to my router - is not a router problem as other devices at home do not.

Again any help for the foregoing would be greatly appreciated - I can't seem to find a lot of people with the same phone as me and so there are not many solutions.

Thanks in advance,

ADI

Good then all problems above have been fixed with an update of the driver from intel.

I feel silly now haha :/

    The laptop is only 1 month

    The laptop is running windows 8 and has the latest bios update.

    Please help me when I go to boot manager, there is no option for dvd theres only one efi and boot from the operating system.

    My dvd player works perfectly when I'm on windows 8, so there is no problem with the drive.

    Help, please

    Thank you.

    Here are the specifications of your ENVY HP dv7-7334ea Notebook computer. Please see "on UEFI and Start Menu" and "Start secure (Windows 8)" for more information about the use of your computer.

  • I'm new on iMac, a lot of questions.

    I have, after 20 years of Windows, made the leap to everything Apple. I had all the other devices (iPhone, iPad, etc) for a few years and finally got an iMac. It's a mid-2011 21.5 "model low spec in entry for me. I had it a few days and put everything in place as well as an upgrade of the El Capitan.

    There will be a lot of questions, so I'll post them in this thread instead of making several for each topic. The biggest problem is that I don't know anyone with an iMac to help me and even if I have a question I don't know the terminology to explain my question to the public online. So, having said that, my questions will be very simplistic in the wording of the description.

    The bar downstairs, the dock, I believe it is called, features icons (apps?) and in some, there is a black dot. What is this point?

    I was very surprised to see the word "Windows" in the menu bar at the top of the screen. What do you call this bar at the top of the screen?

    There are 18 000 + photos on my Windows PC, if I move all these images the iCloud iMac will fill them to my other devices? Do I have a choice as to what photos I want to be on every device?

    I don't see anywhere a reference to the video or video app on the iMac. I have videos on an external hard drive I want to import on the iMac or I have to keep on the external hard drive? It is a Western Digital and I'm not even sure that its format will work with Apple.

    How can I turn off the monitor with the keyboard (2009)? Has it a function Alt + F4 to close a window? The F4 key, I get what he's called Launchpad. However, the key F3 that spread out the windows on the screen, which is that the called function?

    Where can I find my "recent items" like on Windows menu start?

    How do I get Numbers, Pages, and Keynote on the iMac because they are on my iPhone and iPad?

    Well, that's it for a start, but I know that there will be a lot more questions so please be patient with me. Thanks in advance for the help!

    The black dot means that the execution of the program indicated by the icon

    The bar upstairs is the menu bar

    If you have enabled the iCloud photo library, you can import your pictures to the pictures on the iMac and they will be loaded in iCloud, know as 18 000 images may take a very long time to load (days or weeks)

    Any other device using iCloud photo library will get the whole thing, an option is not available with device.

    You cannot turn off the monitor

    Recent Articles are visible under the small Apple (top left of the menu bar)

    Pages etc. can be purchased from the Mac App store.

  • I read this topic (I have a lot of questions about Xperia Z2 with lollipop)

    Hello world. I read this topic (I have a lot of questions about Xperia Z2 with lollipop) and I have posted a question, but it seems that no one saw him. That means the following: (how can I install the source application unknown to other users in my phone because it is to the unknown source menu is disabled in the settings-> Security)? This means that I can not install all the apps if I switch to the lollipop? Can someone tell me please the exact meaning of this?

    Thank you.

    It's true, but game store will not need this option checked - loading of a file manager will - but which is not say that the application will work once installed

  • Build lab ESXi for new user. low cost and power, a lot of questions

    I've never touched of ESXi, but a customer is going to have it in place so I want to get familiar with it to some extent. I need a reality check of some of you who know what you're going before I start ordering components. I'm not trying to become an expert to ESXi, I just want to know my way around.

    I would like to build a mini server that uses ESXi, and that hosts Windows 2008 Server to act as a domain controller for my small network. This is the only use for the server and ESXi, but other needs can happen, and I want to be able to test other virtual machines within ESXi.

    I have read through a good number of blog posts on the creation of laboratories of the House, and those who have let me know to a certain extent. But still, like a newb, there are a lot of questions. ESXi is not a normal BONE, and I would like to get things right the first time.

    Given that the box will be on 24/7, I would like to lower energy consumption. Performance is better, but I like to keep the use of the power down. I'm pretty sure I'll be able to do without a video card. I'll go with a kind of small form factor case, and the motherboard will probably mini itx or micro atx.

    Here are some of my ideas, if please correct me or suggest that you feel appropriate.

    1. As far as I know, ESXi and vSphere Client all I need VMware and are free for my use will be.
    2. I'll be able to install x 64 guests in ESXi, correct? (I think if ESXi is running inside vmware workstation, only x 32 guests work?).
    3. Is it true that a single physical NETWORK card is necessary for my simple needs (not really sure on this subject).
    4. I was going to get an i3, but am now wondering if I should opt for a faster chip. I almost always used Intel for my desktop, but would consider AMD if it aligns well (power, graphics, mobo that works well with ESXi). I3 is the less power-hungry, but it's not clear to me that one of the faster chips will pull down a lot more power in standby mode. This server will have a quiet life. If it becomes more than one domain controller, it's ok if the power use goes up. I want to just make sure that it is intended as a DC for a very small network, it uses power as little as possible.
    5. I would get a mobo that has a compatible network of ESXi on that card, but those who seem to be quite rare, or the less difficult to ID. I'm guessing that the integrated nic will be less power hungry? Suggetions mobo?
    6. I'll use a 2.5 hard drive "to save energy

    Indeed. In this network interface cards, Intel 82574 L is of approximately $30, the street.

    To develop further-

    #1 Yes

    #2 Yes, as long as the chipset have VT-x (Intel) or AMD - V (AMD).

    #3 Yes, other network cards is for redundancy, load balancing, and the separation of traffic

    #4-6 should be addressed with the links above.

    Edit - link added to VT - x

  • HP dv7 stopped envy

    Hello

    My HP envy dv7 laptop stopped and it does not restart. It happened while I was watching some cartoons on youtube. I tried to do a hard reset but it did not help.

    The laptop was running on AC right now.

    He did not show any error that might predict a failure. The only thing that was a little strange, it's that he asked permission to update everyday Java, sometimes even 2 times a day. And especially when I was watching full-screen movies offline or online. But I thought that Oracle made a lot of updates.

    Is there a fuse that can be checked?

    Please help put back on!

    If the laptop does not work without this is battery problem. Plug in your laptop. You can buy the new battery. But if laptop stopped working and you can't do anything or slow work.  I think it is problem with high temperatures in the processor.  It's maybe inside the laptop to dust.

  • Dv7 - 7333cl envy: Boot Device not found (3FO) after 8 of Windows Restalling of recovery disks

    Hello

    The hard drive on my dv7 desire - 7333cl just died after upgrading my windows 8.1 to 10. I bought a new SSD and I replaced the drive. I could not find the recovery discs, that I did when I got the PC, so I ordered new HP according to the recommendations of other threads with the understanding that they would be able to reinstall windows on the new drive.

    Given the shipping time would take a long time, until I tried to reinstall Windows 8.1 using the file .iso Windows 8.1 image official of Microsoft. It seemed to install properly, read the product automatically key and everything, but I could not get the machine to start, so I decided to wait for the HP recovery discs.

    Well I had the disc a few days ago and reinstalled the original image on the new drive. Problem is that when the computer reboots, I get error no matter what I try. The errors vary according to which of the steps I tried below, but I was never able to start Windows, except once when the Windows 8 BSOD loops and restarts automatically before I can even read.

    Here are the steps I've already tried:

    -Performed a hard reset (power adapter and battery removed, taking the power for 30 seconds button)

    -Run the diagnostic system HP based on the SSD (spent) and memory (spent)

    -Secure boot disabled (and re-enabled, cleared the keys, keys reloaded, etc.)

    -Enabled legacy support (and disabled)

    -Bios reset to original settings (F9) is then repeat above steps in various orders

    -Reinstalled two times more than original image

    At this point, I was wondering if the drive has not been formatted from the recovery disk and multiple files to start causing problems, so I started in Parted Magic with UBCD and reformatted the entire hard drive (0 s to write to disc) and again reinstalled original image. Still nothing so I told all the steps above in random orders to try to turn it on.

    If I start in the boot options, I can see the SSD, but it still won't start. Does anyone have more ideas for me to try? The fact that it passes all the tests and that it is running the Linux of Parted Magic environment suggests that everything works fine, but for some reason any Boot file does not load.

    Did I lose money on the HP recovery discs and he just bought my own Windows OEM license?

    I'm going crazy trying to figure this out. I am relatively experienced with the PC, but it's my first time work with the architecture of the UEFI Windows 8 so maybe there is something obvious that I'm missing?

    Thanks for any help.

    FINALLY SUCCESS!

    After a lot of frustration and several reboots, partitions, reinstall, and trips to Best Buy, that I care to remember I'm typing this from my stable work feel LIKE to the point Windows 8.1. Currently 10 Windows to download and install all updates, but everything seems to be stable.

    To make a long story short:

    -Be sure to carefully read the product manual

    I never would have guessed that this system would support only a 160 or 180 GB SSD. If I had of known that I would have probably never had any serious problems.

    -Instead of order recovery HP discs just to download the ISO of Windows 8

    I'm not the first person to have problems with these discs (search this forum for the many complaints), so unless desperately want the included HP tools and bloat, just to get a file from Microsoft (FREE!). There is no reason why it shouldn't work and I wish I would have went with my gut here and saved a bit of money.

    -Be persistent if you can't find the question

    I was told, many people, that the machine was bricked up. At that time, I was obsessed with the implementation because no one could tell me why it would not.

    Thanks for reading! And if you encounter a similar error, good luck.

  • Dv7-7250sw envy: replacing the motherboard in Envy dv7-7350sw

    I have some questions to ask:

    1. is it possible to replace the motherboard in this laptop with motherboard with better graphics card? If there is could you write a serial number and model.

    2. my motherboard is broken - beyond repair and I need a new, same motherboard that the original is not found. Is it possible to order directly form maker? If there is, I would ask for contact and some tips.

    I'd appreciate any help ^^

    You have listed two different models, of which one is an AMD processor and the other is Intel. I will assume that you have the Intel model. Otherwise after return to clarify and we can do it for a model of AMD. Even if you have a processor AMD motherboard described below would be better, but you will have to get a motherboard and processor, of course.

    Here is the Service Manual:

    Your manual

    Your listing:

    You have an i7-3630QM and nVidia GT650M video.

    The jury will have a faster processor; up to an Intel Quad Core i7-3840QM but it is no better than the 650 M video, you already have. In other words, you have the top of the motherboard brand for this model, and no better motherboard will fit in the chassis.

    You have this motherboard:

  • Dv7 HP Envy notebook: update the BIOS

    I have a laptop HP Envy dv7. When I turned it on this morning, I got a message that he was updating the BIOS.

    I tried a system restore, which did not work. I ran diagnostics and everything seemed OK.

    I can't find my recovery disk. Anyone know what I can do?

    I hit escape to enter diagnosis, and if this can help, information on the system gave me-

  • HP Envy 15-j190nb update question

    Hi all

    I have a question about the HP Envy 15-j190nb.

    I'm looking for a laptop about a new study that I will soon begin. My eyes fell on the HP Envy 15-j190nb .

    The specs are really good for a laptop, but I was wondering if I could install an Msata SSD and Windows of her boot.

    Basically, I want to keep the 750 GB HARD drive as a device to store my data and the SSD as a boot device.

    The question is, is it possible? I searched the Internet for a bit and saw that the old Envy 15 models were not able to boot from the disc Msata, because they removed this option in the Bios. The only thing that could do the job was if you removed the preinstalled HARD drive so that the laptop would automatically detect the Msata drive as a boot device.

    Now the articles I read are from somewhere last year so I don't know if the problem I described is still there.

    I'm looking forward for an awnser

    Problems still there. You can also run Windows of the WSSD, if you configure a bootstrapper on the main drive, which is quite advanced things. I'd say you'd be better off just replace the mechanical drive with a SATA SSD.

    Fortunately, it's one of the models where the hard drive and the WSSD are easily accessible.
