U2715H go through the powersave mode

Hello

I have a problem with a relatively new U2715H.  It was working fine, but now I can't get a signal in my office (Windows 8.1, Nvidia 670GTX, the latest drivers).

I tested with my computer laptop (mini DP) and monitor (DP) and it works well.

However, on my desk, I get the "entering Powersave Mode" when I try to connect to it.  I tried HDMI (two ports) and DVI - DP.  I did a factory reset, but failed to get any signal from my office on this subject.

Any suggestions?

Thank you

* The computer and monitor are on
* Press display Menu button to open the OSD (On Screen Display) menu. It opens?
* If Yes, go to the input Source
* Try to select using two HDMI (MHL), one at a time

  • Printer OfficeJet 4500 is not the powersave mode

    I just got a printer wireless HP OfficeJet 4500 (CN547A). This printer seems to be all the time and won't in powersave mode. After discussions with tech support, my understanding is that if no print jobs are sent to the printer at the end of an hour, the printer is supposed to enter powersave mode. I do not understand why it remains online in the State of full power all the time. I first asked HP support about this and they had me unplug the printer and press on and press and hold the # and 3 while plugging him back in. That seemed to put the printer in mode powersave, but then as soon as I printed something, that he would stay in line other times, as in, it would still be online in a status of full power several hours after it printed something. The next technician I chatted with that suggested I have unplug the printer, then press and hold the # 6 button while plugging back in. That was exactly equals the previous reset method. Why the printer is not entering powersave mode?

    I have the same problem.

    Product name: HP Officejet 4500 G510n-z

    Model number: CN547A

    Firmware: MWM2FN0944AR

    I tried unplug him and plug in now # 3.  This just reset the values by default, so I need to hang it on the wireless connection.

    I did a scan and he returned to power in 20 minutes saving mode.  However, I printed a test page (google.com search), and it has been two hours and not yet in power save mode.

    AFAICT, there is no firmware available to upgrade the Officejet 4500.

    6 sec more lost/stolen iPhone. Turned on the 'lost' Mode and displays the number to call if found on-screen. It is w / "Find my iPhone", went up, no response from any home in the area. Later received an email that it was found, still no call to the number on the screen. Several unsuccessful attempts to get it back, now the phone is in offline mode and says that the history of the site is not available. I left a note on all the doors in the place indicated on the "find my iPhone" describing my phone lost and left a number to call. I am leasing through the iPhone upgrade program. Help, please.

    There is no way to locate now, unless the one who found it exerts a force on you contact on this number you posted

    The good news is, since you have find my iPhone, they will not be able to reuse the phone even if they are trying to restore. Unless they know your password, or you have a valid proof of purchase AGFI won't be deleted.

    So if the person who found the phone knows about it, he or she would rather go back because it would be of no use to them.

  • High utilization of the processor in Mode VSS when traffic through the internet.

    Hi all

    I have a problem with the installation of VSS. The VSS service install act as a central office switch of transit for internet traffic and the problem arises when there are about 600 Mbps of traffic through the switch. We notice that there are a lot of packages being softswitch and the rate is quite high, almost like 100 to 200 k per second.

    The VSS switch manages ospf and BGP and have plenty of internet routing. After investigation of high CPU usage, I noticed that the AAGR switch is full and has tried to set the course of max mls to the maximum cef and restarted the VSS service.

    Unfortunately, the problem persists after restarting.

    We had planned to filter the full internet routes and enable by default and ospf route only in the VSS service and restart the VSS service to make sure that the table AAGR is not overloaded.

    If I fail the next step is to return to autonomous mode and hope that the processor will not pull up.

    My Question: These step will prevent the issue? Suggestions or the reference similar to the problem I am facing in?

    Hello Sophie,.

    unless you have a PFC 3CXL and all the DFCs the AAGR 3CXL can manage only 256 000 IP prefixes and nowdays that complete a table is in order or 310-320 000 routes.

    See

    http://www.Cisco.com/en/us/prod/collateral/switches/ps5718/ps708/product_data_sheet09186a0080159856.html

    See table 1 in the second link it tells what I wrote in the first line.

    > We planned to filter the full internet routes and enable by default and ospf route only in the VSS service and restart the VSS service to make sure that the table AAGR is not overloaded.

    You should not need the device after accepting only the default route in OSPF or BGP AAGR use will be greatly reduced this is just wait a few minutes (unless there is an underlying SW bug) for the MSFC to update CFP and then all DFCs

  • The mode of maintenance ESX through the vCLI

    I wonder if it is possible to hire a full maintenance ESX mode using the vCLI.

    There are at least two controls available, but non of them wishes to migrate virtual machines to other ESX hosts running.

    -However - possible thats using the GUI of vCenter. If you enable maintenance ESX in UI mode, running the THAT VM will be migrated before the ESX Server is in maintenance mode.

    Unfortulately VM migration manually through the vCLI could also not an option, given that DRS could start moving another candidate VM back to the ESX Server, which should enter into maintenance mode. To avoid this, should also stop the automated mode of DRR.

    It would be great, if there is a command or an available option, which would make all this automatically. Since it works with the GUI, it shouldn't be so difficult start this process also the vCLI.

    Perhaps it is already implemented - and I don't know about it. So any advice would be more than helpful.

    Otherwise: are there other ideas (scripts may be already available), which would help here?

    In fact, there are a variety of scripts provided with the vCLI that many are not aware of called "vSphere SDK for Perl utilities" and the other that hostops.pl allows you to perform various operations of the host against a specific host ESX (i), unfortunately the version implemented by VMware does not properly a vCenter cluster maintenance mode and therefore if you used He would have not evacuated running virtual machines.

    Quickly, I wrote my own version which takes account of vCenter, this script must be run against vCenter with a list of host ESX (i) to perform a certain operation and the latest version of the script, it supports the two enter/exit maintenance mode.

    Check out this script for instructions/requirements:

  • can not recharge the iPhone through MacBook in mode 'sleep'

    I used to be able to plug my iPhone 6 on my MacBook Pro from one day to the next and it would be both sync and charge with the MacBook into sleep mode. I recently bought a new MacBook Air, and as a first step, the phone has continued to charge when plugged into the laptop mode "Eve" - but now (about 2 weeks later), is all of a sudden. Clues?

    You can try these settings on your mac:

    Go to System Preferences > energy saver

    Farm settings

    The power adapter settings

    The important thing is to not check "put hard drives to sleep when possible", all usb ports will not be powered when drives are sleep

  • Currently, I am running Windows 7 but to install a range more network adapter Linksys which is only compatible with Windows XP. Can I use the compatibility mode and install through XP?

    You can understand that I want to change my office from Wired to Wireless and really to have the adapter installed in the back of my Office Wireless (with dual band antennas).  The Linksys device is not yet recognized because I'm running Windows 7 while trying to install the drivers which are only Windows XP and previous versions. Is it possible to USE the Windows 7 compatibility mode > XP and still have a stable system when I'm not using the adapter. ?  Really appreciate the help of someone who can advise me.

    Thank you all very much,

    Hi Roger

    The Compatibility Mode works with hardware or software drivers. This mode is less reliable when installing the hardware drivers that it is during the installation of software.

    If Compatibility Mode fails, your only option would be to check with the support of Linksys.

    Concerning

  • Four express airport Wireless extends through the other, instead of directly through my airport extreme

    Hello

    I have a small question which I hope someone can help me with.

    I have an airport extreme that I use as base station, and since I live in a big house, I extended wireless network with four Airport express devices. I put express devices from the airport in mode "expand the network."

    The question I have is that two of the expresses correctly connects directly to the Airport extreme, but the two other go via the two expresses first and not directly to the airport extreme base station.

    I am worried that I have will lose speed because of this and wondered if I can implement all the features four Airport express way so they all connect directly to the base station and not by the other?

    Any advice would be appreciated - thanks.

    I am worried that I have will lose speed because of this and wondered if I can implement all the features four Airport express way so they all connect directly to the base station and not by the other?

    Apple "extend a wireless network" feature works on the strength of the signal, so the ideal situation would be to have AirPort Extreme, located within your home with each Airport Express located approximately the same distance from the AirPort Extreme around the perimeter of the House.

    Think of a 4-spoke wheel. AirPort Extreme would be the "hub" in the center of the wheel and located at the end of a ray separated from each AirPort Express Terminal. In this way, each AirPort Express connects directly to the 'hub' and expand properly.

    The question I have is that two of the expresses correctly connects directly to the Airport extreme, but the two other go via the two expresses first and not directly to the airport extreme base station.

    The two airport expresses which connect to other expresses 'extension' of the network are not all. They 'join' the network... so they could be used for AirPlay or a printer USB remote... but the Express do not 'extends' the network when he "joined".

    You will need to experiment with different places until you see all four expresses connect directly to the main AirPort Extreme.

    As loss of speed in the network is... whenever you try to extend wireless network, nearly half of the potential speed on the network will be lost in the process. It's just a character of the beast to the extension of a wireless network.

    You can avoid the loss of speed in the network by configuring each AirPort Express Terminal to connect to the main router using a wired Ethernet cable connection. There is no loss of speed at all through the connection Ethernet cable up to 300 + feet, so full power is stored on the network when you do it this way.

  • Access to the Safe Mode on Windows 8

    Hello

    I understand sometimes through troubleshooting or for other reasons, there is a need to access safe mode when using windows 8.

  • Manual mode is fuzzy until after the autofocus mode

    I recently bought a refurbished T5. I learned how to use manual mode, and I understand very well now (at least I think). However, I was a problem. I'm going to start shooting in manual mode (lens and body) and everything will be blurred - the image in the viewfinder that I take the picture and the resulting image. I'll then go in autofocus mode, and the image will have very similar parameters and get the Crystal. I'll then go back to manual mode with the same settings as I had the last time I was in manual mode, and the image is now perfectly clear as well through the viewfinder and the resulting image. If I have the correct settings, why not the picture will be clear the first time around? I'm doing something wrong or is there something wrong with the camera itself? Thanks in advance for any help!

    I have included some images to help:

    So I turn on my camera, the lens configuration and body in manual mode and take this picture. It is 1/80, f 5.6 and (self) ISO 2500.

    Then I go my goal and my auto body and get this picture. It is 1/60 f5.6 and ISO 2000.

    I then my goal and my body return to manual and get this picture at 1/80, f5.6, (auto) ISO 2500.

    How the same settings can produce different images? Did I miss a step or something? Please let me know!

    You seem to get the manual exposure mode mixed with the manual focus mode.  They are two different things. On the goal, when you switch to M, you use manual focus. You must turn the focus ring on the lens to focus. On the dial to camera mode, you change Aperture, shutter speed and ISO manually to chane exposure (brightness of the image).

    The first time your goal is be blurred. After you return to auto, it twists the ring for you as it so now the lens is in short. Even after that you changed it to M, the lens is always point to the same object... If you aim now to something else more away or closer, then it will be fuzzy in M on the lens.

    I recommend that you leave the lens on A. There is no reason to use the manual focus unless you need areal or you understand what you need to do.  Similarly, there is no real reason to use the manual exposure in order to use manual. Use it when you need which means that you must first understand what it can do for you. I recommend your use Av or Tv mode first before trying the M mode.

  • Problem with the files not showing (after changing the USB mode)

    I have a sansa fuze 4 GB. version V02.01.09A. OS: Vista Service Pack 1. My rocket was working fine until about a week ago, when it stopped charging. but after installing the new norton 360 sansa is more appeared in my computer or Windows media player at all. I tried updating the driver but it says that the pilot was already up to date. I tried other USB ports again (front and rear), did not work. I decided to change the USB mode and it has finally started to load again in MSC mode.

    now, for the problem I currently have and, when I click on sansa via my computer and go to the music folder, it says "this folder is empty". I unplugged and watched in my music list, and all the music is there. I tried to put a new song on the player, disconnected, and when looking through the songs of the player the new song is here. I reconnected it, the new song is in the music folder, but the other songs are not listed. In addition, I have a microSD card that is listed as "o" in the car, all the songs I had on this appear, but not those on memory internal to the sansa.

    How can I get again list all music files in the folder?

    Note: I do not sync as it has only some of the songs I want on my sansa. the way I add songs is to copy and paste to the folder of the sansa player

    Okay, I don't know why or how, but it works now in MTP mode. I saw you are solutions, but I decided I'll just change the mode before trying to have ideas. until I reconnected it I also removed the microSD card, and it worked perfectly (make a backup of my songs). the problem could have the sd card in all this time?
