Identification of variants of reference model.

Hello.

I see that in a model of ThinkPad, there are several variations.

For example, a T520 4239-46U and T520 4239-CTO.

I guess it comes to the different configurations. Where can I find out what each of them is composed of? And the numbers themselves relate to any particular aspect of the model, for example, isn't 4239 46U CTO make reference to a particular component or they are "figures" without any real meaning?

Thank you!

You can search a model here: http://support.lenovo.com/en_US/downloads/default.page?selector=expand#

Models ending with "CTO" mean configured on command, so you would need to look at the list of components here serial number:
http://support.Lenovo.com/en_US/product-and-parts/partsLookup.page

"CTR" is as a technical manager, except that they are refurbished. Traditionally, the models ending with a 'U' are US Setup.

  • Confusion on the tiny model M92p variants and differences

    Hi all

    I make a purchasing decision for M92p tiny (do not know what is the appropriate form for him, is it SFF or USFF or something like Mini ITX).

    I can see on various websites there are different model variants listed for this series, for example on the official lenovo, he mentions around 9 variants of M92 and M92p.

    http://support.Lenovo.com/us/en/documents/pd024438

    So, I'm totally confused as to what is the exact model, I'll buy. If anyone can, then please answer the following queries:

    1. What is the difference between M92 and M92p (known as "tiny")

    2. What is the difference between all the variants of the model numbers on the support Web site. I'm a 3235, he therefore M92 or M92p.

    3 in case to get accurate detailed data sheets for all model with the numbers part numbers so I tried option but it did not. A web link would be really useful.

    Hello Johan,.

    The OSI networking reference model (ISO 7498 - 1) is designed around seven layers arranged in a stack.

    The OSI security reference model architecture (ISO 7498-2) is also designed around seven layers, reflecting a high level of different requirements in the security of the network.

    In the OSI model, each layer has its own functionality and according to which it has features of different security as shown below.

    Application - authentication

  • Workflow does not inherit model of workflow activities

    Hello

    JDeveloper Version: 11.1.1.7

    We have a problem with the use of models of workflow by reference.

    Requirement: We would like to make a call to a method of custom module ADFbc calls as the first step of our BTF.  We would like that this is part of a workflow template so that it can be reused.  We always want the workflow reference model in case it changes in the future (reference instead of copy).

    Question: I create the model of workflow with a single call to the method of the AM.  I have create a new BTF based on this model with a view single activity.  When I run my BTF as a BTF view activity on a page region is called as the first activity.  The activity related to the AM method in the model of workflow never gets called.  If I uncheck the activity seen in the BTF as the default activity, activity at the AM method is called in the workflow model but the activity of the view in the Working Group is not called.

    I understand that when you use a workflow template reference work that you can not see the activities of model in many of BTF to 11g R1 but how do we use a model of workflow in collaboration with a working group to call all the activities in the model first before starting the activities in the Working Group?

    I am sure that it is user error, but have yet to find the cause.

    Any help much appreciated.

    Thank you

    do you have a wild card from the navigation in the BTF who calls the view in the Working Group, when default templates activity finishes its work?

  • How to use the model taskflow

    For some of my workflow, I want to check something before running the workflow. If I I could use taskflow model but I don't really understand how it works.

    In my workflow model, I have a router that has 2 results a default result refused and the other with an expression with a result obtained. Then, I created a stubborn workflow based on this template.

    Q: how associate you the result of the router in the model entry in the btf child?

    What I don't understand is how to use the result of the router.

    Note: I want to use the flow of tasks as a reference model not copy

  • Pavilion e9280t: the graphics card upgrade

    I had to spend my original GeForce GT220 graphics card to use at least three 3 monitors so I bought EVGA GeForce GT 640.  When I installed the card, everything was fine until the computer, install the driver and start then computer began to stop and start several times and then stopped at c prompt and siad it is impossible to find a bootable.  Long story short, I had to use my emergency disk and restart the computer.

    Then, I started reading Blogs about the HP graphics card chain and one of technology pointed out I should buy Nvidia GeForce GTX 660 and this card will work without upgrading PSU, so I did.  Now, with the GTX 660 computer card keep start and stop and I can't seem to stop.  I spoke with a few outside tech and they said that I need to improve my diet.  If this is the case, then the HP expertise technology was not entirely accurate or I have another problem.

    The UPE recommended are: (1) Corsair HX650 and (2) RS-650.  I also read that this MB Pegatron IPMTB-TK does not many power supplies above 550-650 watts.

    Can someone tell me what is my computer problem?  Need to pass the power supply and if I do what PSU I can use?  Model and Type to fit properly in the case?

    HP Pavilion e9280t Truckee-UL8E

    Chipset: Intel X 58 Express

    Original power output power: 460 Watt

    Hello

    The differences between the reference models and variants will vary according to the manufacturer.  See the image below and notice number 6 power connectors that are necessary.  Depending on the configuration of your PC, a GTX 660 can't get enough power to the 460 watt power supply in your PC. As I said earlier, I didn't have a question of power using the EVGA GTX 660.  Graphics NVIDIA GTX 660 cards are border line with some power supplies according to the design of the PSU and the loading PC.

    The Corsair CX500, or CX600 would be excellent choices. Note: the power supply fan is mounted upward toward the top of the Cabinet because it will shoot in the air fresh from along the edge of the top side entries.

  • LaserJet P1606dn: Win7: Over Ethernet: list of current control Codes (PCL 6?)

    Thank you.

    I searched in vain a list of control (PCL 6?) for the LJ P1606dn codes so I can work codes, such as "Page Eject" in a database application I'm prototyping.

    Many references PCL 5/5 on the Internet, but nothing related to the current culture of LaserJet printers.

    Appreciate any guidance.

    Yours,

    Bruce Chitiea

    SafeSectors, Inc.

    The LaserJet P1606dn printer is a device based on the host (see http://support.hp.com/us-en/document/c01995860 ).

    This means that it does not include traditional Page Description languages (PDL, s) - PCL5, PCL6 (aka PCL XL) or PostScript - such as used on the more expensive models.

    The host-based devices use owners (unpublished) languages that vary from a model and manufacturer.

    I think that many of the models HP, the language is known as JetReady, which is (loosely) based on a variant of (very) stripped of PCL XL; most of the fomatting is done from the host work station (where the name), with all (text & images) converted to encapsulated, compressed image dithered. interpreter in the printer just unencapsulates and decompresses these images and prints the points resulting.

    Note that even the printer supported standard PCL6 (PCL XL) PDL, it is extremely difficult (in most cases impossible) to inject anything (such as your "page eject") in the flow generated by the driver, due to the highly structured nature of the PDL.

Over time, GPS receivers collect and store data that can be used to help either place resolves quickly and accurately. However unlikely, is that a GPS receiver can get into a bad state, it may still be necessary that it should be reset. What each type of reset means may depend on the GPS receiver (it can vary between phone models). Some things can be qualitatively derived type name and knowledge of GPS terminology.

    Be aware that if you set the reset of the receiver is not actually reset until a post is requested later (i.e. by calling QGeoPositionInfoSource::startUpdates() or QGeoPositionInfoSource::requestUpdate ()). Also, the reset may cause a significant delay until the next update of position occurs.

  • Pro Tips: Troubleshooting scan to E-mail questions in e-all-in-one printers and ePrint

    Hello e-all-in-one printer users,.

    If you're reading this, chances are you have a problem of webservices in your HP e-all-in-one printer. If you can not scan to e-mail, use ePrint, or get a code application, this post is for you.

    Many of later vintage (2010 and beyond) Photosmart, ENVY and Officejet series e-all-in-one printers share the same Web services and Wireless features. Within these series printer, you can enable wireless and Web services (ePrint, scan to e-mail, printable sheets) connectivity of the façade do their installation for use with Android, Windows, iOS, Macand Chrome OS much simpler than the old printer models. Of course, when things go wrong or there is confusion about the use of the printer and features such as printing and scanning to e-mail stop working, the correction of these problems is the same in most of the models.

    WebServices are not connected: what affects?

    When the webservices connectivity is lost ePrint, scan to e-mailand pads features will stop working. If you are just getting started with the installation of your printer, the inability to generate a code application (to add your connected HP printer or sign in to Instant ink) can be attributed to not being able to afford Web services. If you are affected by any of these questions, read on. I have some suggestions that might help.

    Ordinary remedies

    • Before set you Web services, make sure that your printer is connected to a network, either via an ethernet cable or Wirelessconnection. Print a report of Network Configuration of your printer front panel (usually this is located under Tools / reports) to confirm an active ethernet connection.
    • If you are connected wireless, touch the wireless icon printer . If you see as connected and there is an IP addresses starting with 192.168... or, 10 grand. If this isn't the case, run the Wireless Setup Wizard to connect you with your network name (SSID) and enter the password wireless you are prompted.
    • Ensure that the date and time your printer settings are correct. You can check and adjust this via the front panel of the printer in most cases and trivia: the printer Web server integrated.
    • Now, with network connectivity guaranteed webservices icon or (depending on model) and try to activate Web services.
    • If you have managed to connect and a leaflet printed, or at the very least, an [email protected] address is displayed on the front panel of the printer, perfect, Web services are now functional. This means that you can now ask your HP printer connected , or use one of the above characteristics *.

    Note that ePrint and scan to e-mail feature are addressed later in this post if you still need help with these functions.

    • If the webservices are always not, try your printer restore default*.

    * Note that this step resets the setting up your printer wireless, address ePrint and other custom print settings. If you have created a custom @hpeprint.com address that it will be permanently deleted. For more information on custom addresses ePrint, click here.

    Here's how:

    • The printer's front panel, press the Setup/key icon and then tap tools
    • Select Restore to factory settings
    • Note this new printer may contain this setting under the heading maintenance of the printer instead of tools.

    Then, to reconnect to your network (wired or wireless) and try to set a manual DNS:

    Make a note of the IP address of the printer.  Then, follow these steps to configure a manual DNS:

    • Enter the IP address in a web browser (Chrome, Firefox, Safari, Internet Explorer), and then press Enter to go directly to this page. This should take you to your built-in Web server (EWS) printer.
    • Click the network tab.
    • In the submenu on the left, click Networking.
    • Then click on the network (IP) address.
    • Click Manual DNS server.
    • DNS preferred as 8.8.8.8 manual entry
    • Auxiliary DNS server entry as 8.8.4.4
    • Click on apply to finalize this change.
    • Note that menu above EWS items can vary in overall models of printers. If you do not see the exact topics that I've listed here, the subtopic you should always appear on the Networking tab.

    Then, press the icon of Webservices or and reactivate your webservices (required for scanning to E-mail, ePrint , and other functions).

    Then, if a scan to e-mail question has led you to this position, tap the scan icon and enter the email address that you want to scan to.  Then, recover the PIN code that you should automatically receive by e-mail and complete your scan to E-mail setup by entering this PIN code in your printer.  Ideally, if you are able to get this good service will be fully functional.

    Alternatively, if ePrint is your main problem and all the above (except for scanning to E-mail steps) suggestions worked, try emailing your printer a print job. If it prints correctly, ePrint is back online. If you are a user of HP ePrint app, the app did automatically detect your printer? If not, go to the application settings and manually add your printer to the app using either ask you code or IP address of the printer. Finally, if you're a printable, user use your favorite applications on the front panel of the printer, or via HP connected.

    There are advanced troubleshooting steps beyond what I posted here and you can find them in the Forum such as displayed by the employees, Experts and members of the community. Start with the basics and if you still can't not to take advantage of Web services from your printer don't be shy to reach out - HP Support Forum's is a great place to exchange ideas and help each other to get the most out of our products.

    Thank you for taking the time to read. If you have any questions or comments do not hesitate to answer.

    All the best,

    Greetings,

    All new users to check in this thread, the first and the main post is a practical resource for webservices connectivity solutions.

  • HP Envy 17 t: what size usb drive is necessary for the recovery of HP Envy 17 t 10 (64-bit) Windows?

    I just installed my HP Envy and wanted to set up a recovery disk.  The USB key must be less than 32gigs, but the example has not been updated for Windows 10 the instructions say.  It shows a recovery screen for a laptop of Win8 with the source of recovery like 17 concerts.   Is there a way to check the requirements for the front to accept the HP one time recovery option.  I have a new 16 GB USB key and wanted to make sure that it is large enough.

    Also do a backup image to DVD?   If so, how many DVDs?   The laptop is new and I added only Chrome and some minor programs.  My data files are always on an external hard drive.

    Hello

    Thanks for posting in the Forum from HP Support.

    To be honest, I don't know what size will be that these recovery files are because they can vary from the version of Windows to another. They can vary from a model.

    In my opinion, 16 GB is probably not enough.

    DVDs are usually 6 (6x4.7 GB = about 28 GB) but this can vary from one model.

    This possibility of imbedding maybe once, there are other ways that you can save your system indefinitely.

    This is a free option included in all windows (creating system image, it's free as included in Vista from the outset).

    http://support.HP.com/us-en/document/c03544793

    However, this option requires (e.g. USB HDD) external HARD disk or DVD. It does not work with USB flash drives.

  • VS replacement cost of Crystal screen protector

    I have a Apple Watch Sport with aluminum body. I tried a few different screen protectors and were not happy with any of them. I know that it comes down to a personal preference as to whether or not I use the screen protector... But nobody knows how much it costs to have replaced glass/crystal if it is chipped or cracked? If it's expensive, I'll deal with the screen protector. If it is reasonable, I could go without the screen protector. Thanks in advance for any ideas.

    Hello

    Apple does not currently offer a repair service screen for Apple Watch of a similar nature to the screen repair service that is available, for example, for the iPhone.

    A damaged Apple Watch may instead be able to pay out-of-warranty repair service. Costs vary depending on model and region. U.S. price information is available here:

  • Re: What is the part number?

    Hello people...

    I was wondering what the part number is suppose to say? Does this affect the specification of your laptop to another? for example, I have this laptop [Satellite A300 - 1 G 5 | http://eu.computers.toshiba-europe.com/innovation/jsp/SUPPORTSECTION/discontinuedProductPage.do?service=EU&com.broadvis ion.session.new = Yes & PRODUCT_ID = 1055589]. As you can see from the link, the laptop displays a part number: PSAG4E-_ * 03801 MG 3 * _. On my laptop cover, the label of the model is identical to the first part, but different on the second, its written like this: PSAG4E-_ * 03801HAR * _, have you noticed the difference? How important is this difference?

    I'll explain why Im concerned about it once I get a clarification on what means the part number... Thank you

    Hello Poison

    AFAIK, part number is a kind of identification number. Each laptop model is available with several different hardware configurations and different hardware components.

    Your Satellite A300 has PSAG4E model number. MU by Satellite A300 has PSAG8E part number.
    When you visit the Toshiba download page, where you can choose model right after the part number. Drivers available for your PSAG4E probably won't be the same as for my PSAG8E.

    I don't know what the difference is, but maybe my laptop model has other graphics card, the sound card or the card wireless network may be. This part of the part number is important to you.
    Other numbers behind this first part of the part number is depending on the country and it is absolutely irrelevant for you.

    So, what's your concern?

  • HP deskjet all-in-one 3632: problems to make eprint to work

    OK, I'm having a problem making the printer to connect to the internet.

    I have a static IP address on my ISP.   I have 1 n600 Router 2 broadcasting networks.  1 5 g and 2 1. 4 g.   I used void net default 192.168.1.1 and 255.255.255.0.   This router I have a win 7 64 home computer hard wired. I also have a hard wired my Office Access point. the access point also broadcast a GIS of different 2.4 g.  all the sig.s wireless use wap2 Protocol and b/g catch up mode. and the names of all different but same network total network, if that makes sense.  OK, I have a total of 4 more also attached computer too either or network win7 32 ultimate win 7 64 and win vista 32. 2 tablets and 3 IH smrt 5.01 lolipop android running.  I have 2 security cams that have a static for IP and port forwarding on them.  everything works fine.  all computers are part of the same private network hmegroup.  I assigned a static ip address for printer dhcp table.  I can print from any device at any time via wifi.  NOW HERE'S THE PROBLEM.  whenever I go to the WEB form, he is saying that its not active all the check boxes and I don't know what a proxy server is but I know that I have not installed on this network so I click No proxy server.  The PRINTER SAYS UNABLE to CONNECT to the INTERNET.  every time that I tried about 20 this weekend.  It says to check the dns, gateway, blah blah blah.  so the DNS are correct and it shows not 192.168.1.1 as the gateway.  He also btw autodetected it correctly.  so when it fails to connect, I click on web print report. I get the page "get the most out of your printer.  and then a white page. and that's all.  at the top of the page to "get the most out of your printer" it says in "BOLD", "your printer is not connected to a network" which is BS do see on every device and every computer wireless or hard-wire. and I open it a new browser window using 192.168.1.143 which is the static ip address for this printer and bam. It opens right.

    When have I forgotten?  can I configure the gateway as the ip of the real gateway side the ISP of my router.   Im a little aggravated because the only reason why I got this printer from walmart that the PHN android already had the makings of plugin hp on them and I don't like HP is cause of all the fluff sofware that comes with them.  I almost had a gun, but they seem fragile and plasticy more than this one does.  so as I said work is expected for printing on the web.  I tried to press the eprint button and it flashes a little and nothing. I pressed it and the 'i' button and nothing ever prints other than the above page.  I have reset to the default values and done everything as configuration 2 x.

    If anyone can help, I would be very happy.

    Hey @Facorbin,

    Welcome to the Forum from HP Support.

    I see that you are unable to activate the webservices in the all-in-one printer HP Deskjet 3632. I want to help you with this. I have some suggestions that might help.

    I recommend you try the following steps:

    • Enter the IP address in a web browser , and press Enter to go directly to this page. This should take you to your built-in Web server (EWS) printer.
    • Click the network tab.
    • In the submenu on the left, click Networking.
    • Then click on the network (IP) address.
    • Click Manual DNS server.
    • DNS preferred as 8.8.8.8 manual entry
    • Auxiliary DNS server entry as 8.8.4.4
    • Click on apply to finalize this change.
    • Note that menu above EWS items can vary in overall models of printers. If you do not see the exact topics that I've listed here, the subtopic you should always appear on the Networking tab.

    If this goes through successfully, try to activate the web services () again. If you're still coming up short after this point, I recommend you enable DMZ mode in EWS your router, manually add the IP address of your printer. (Based on the level of detail, I suppose you're a statement you know what that means). After completing this step try to enable Web services one last time. Success?
