What is the slot labled SC above the HD on my Latitude E6420

I was curious of what was the slot 'SC' above the HD on my E6420 for what a kind of expansion port? I can't find referance it works anywhere on the website.

The SC and the location ExpressCard slot are not the same.  I have a Latitude E6410, and it has a card slot smart (SC) on the left side and a slot ExpressCard (EC) on the right.  The slot of the EC is about 3 times thicker.  The smart card slot is for reading chip (http://en.wikipedia.org/wiki/Smart_card) and is a way to check someone's identity to allow them to use the computer and is shared with the Government and various companies.  The slot Express Card (http://en.wikipedia.org/wiki/ExpressCard) is for expansion devices, such as wireless or USB 3.0 ports maps.  ExpressCard is the newer and faster standard replacement for older PCMCIA cards.

  • Temperature of the GPU 103C on Latitude E6420

    Hi, I recently started the Test PassMark Burn-In version 7 on my i7-2630QM Latitude E6420 with Nvida NVS 4200 M 512 M card. During the test, I noticed that the temperature of the GPU is about 103C and software reported "Test failure" due to the high temperature.

    The temperature of the CPU is also high, around 93 C.

    Is this normal? I would return this laptop?

    Thank you

    It is a known problem with the E6420 14 "laptop and the Quad core CPU. I have an E6420 and E6520. The E6520 manages the heat much better and higher out of GPU and 95 c 85 CPU when you run Diablo 3 for an hour on the resolution max and max graphics settings.   My laptop comes with the heatpipe heatsink only, he would downclock the CPU because of excessive heat and same judgment. After I got the radiator double pipe with a new thermal pad, my time is up to 100 ° C max on CPU and GPU and cell phone stops is more due to overheating.

    The problem is Dell packed plenty of power in a computer 14 "laptop. When running at load max, the cooling system can not just keep it up. Dell should really fix this, but you can do some improvements on your end. FYI - don't try if you are not comfortable to do this or are tech / mechanical savvy.

    Here's what I recommend:

    1 make sure you have the latest version of the BIOS installed. Dell changed the thermal curves for the fan of the bios updates.

    2 make sure you have the radiator HEATPIPE DUAL DELL P/N - TYP01. My E6420 comes with heatsink tube bad in the photo below.

    One pipe radiator - ONLY for the DUAL CORE i5, i7. NOT FOR i7 QM QUAD CORES.

    Forum.NotebookReview.com/.../564579-E6420-Owners-thread-83.html

    There is a "gap" between the radiator and the Nvidia NVS 4200 M GPU. Dell uses a NOTE from the ADMIN: profanity removed according to the TOU > heat transfer heat pad. many users have done the following to reduce even lower time by replacing the thermal pad with a wedge of copper sandwiched between two layers of thermal paste / compound. I don't know that Dell probably does not support below this mod even if users have reported the lowest time after the mod which stresses in turn of components less.

    3 order the copper shim kit. www.eBay.com/.../260718120394

    4. use a good thermal paste / made up for example ceramics 2: www.newegg.com/.../Product.aspx

    Finally - browse the forums on this site because there is a lot of information on your E6420.

  • Missing menu of BIOS activation to activate the keyboard backlit on latitude e6420

    Hello

    I bought a backlit keyboard for my 6420 latitude which was only equipped with a model not illuminated at the time I got it.

    By pressing Fn + >, nothing happens. I have read many things on the web, and it seems that we must go into the BIOS and enable the backlit. I said I should find the menu under system configuration and illumination of the keyboard, but I do not have this menu...

    I also had a quick glance and shortcut keys and were those related to the backlit keyboard... Looking at the Control Panel, properties of the keyboard, I do not have the backlight tab, «Brightness keyboard»
    Anyone know how I can activate my backlit keyboard and detected it as such?

    Before buying the backlit keyboard, I am in contact with Dell support to make sure that I can upgrade my laptop with a backlit model without facing compatibility issues. They told me that I just needed to order the backlit model as a spare part and it will work... but it's not...

    Did someone knows how I can get the backlit keyboard work or is it just bad luck and it would never work? Thank you in advance for your help!

  • What is the best RAM for Tecra A3 upgrades

    Hello

    What are the type of RAM I can install safely in my Tecra A3 better/faster?

    I ran a test with 'CPU - Z', and it tells me I have a 512 MB of memory, having sat on the #1 slot, type DDR1/PC2700 / 166 mHz.

    I would like to have at least 1 gigabyte of memory, but I'm not sure of the following:
    1: the motherboard supports DDR-2 RAM or DDR-1 to faster bus speeds (566, 333 or even at 800 mHz)?
    2: can I install another type of memory alongside the current (see above question)?
    3: make a performance gain by having all the RAM in one slot/block, or vice versa?

    Thanks for the replies!

    Hello

    This utility is not known to be, but I think that it provides the right information.
    You know the software "Everest"? It is a hardware diagnostic application. It's not bad.

    In my opinion, you should use the RAM modules recommended by Toshiba. In my opinion, you will get the best performance with these modules.
    I found a few compatible modules:
    PC2700 256 MB (PA3311U - 2M 25)
    PC2700 512 MB (PA3312U - 2M 51)
    1024MO PC2700 (PA3313U-2M1G)

    It seems that these modules are SO-DIMM 200 pin - DDR 333 MHz.
    In my opinion, you need to buy a 1 GB and use it in the slot one.
    In the future you can easily switch from the laptop to 2 GB

  • What is the maximum Memroy for an Inspiron 580?

    I am confused about the maximum memory for the Inspiron 580.

    On the Dell website, it has that 8 GB is the maximum.

    When I run the Dell Support Center software, click on the tab of system details under the heading SYSTEM MEMORY, it indicates the maximum supported memory is 16,00 GB.

    What is the right answer?

    J. Gray and yes I did.  As I posted above.  Its been running 16 GB for about 4 months now.

    According to Panel... it shows an i5 CPU 650 @ 3.20 GHz with 16 GB of installed system, 15.8 GB usable.  64-bit operating system.  NOTE: the RAM is outside the EEC

    And Yes, it is a Dell Inspiron 580 (per plate).  In the event that it is lost above, I wrote on 29/12/2015 (so you have the price, PN and source):

    I just powered up with 16 GB in my Dell Inspiron 580.  It has 4 RAM slots now x 4 of them at $21 / each (on ebay):

    • 4 GB DDR3 PC3-12800 1600 MHz 4G MEMORY OFFICE 240-PIN Non - ECC RAM CL 11

    I was careful to cross reference, which would be and how fast it was.  These are faster they must do, but they were also the cost lowest.  The 'old' were DDR3-1333.  So these are the fastest (doubt that helps the machine go faster), DDR3-1600 (PC3-12800, alias).

    I have had this PC i5 for about 5 years now.  I had thought that it was getting old/obsolete, but when shopping is not not bad.  So, $80 brings me 6 GB to 16 GB.

  • What is the best for my professional job or the retina

    Hello

    I need tips for buying a laptop Macbook...

    My job is to develop software for linux and windows systems, the software I develop usually require a connection to external devices via ethernet and RS 232 ports series, apart from that for windows, I have several special software which I use for programming of robots for use in industries and also the software IDEs for systems shipped as Cypress etc of Microchip.

    Linux I mainly use to develop applications for computers beaglebone and Raspberry.

    Using a Mac system means that I can develop also on Xcode for systems Mac OS x, something I wanted to do for a long time.

    I intend to run these operating systems (Windows and Linux) as the guest systems using VirtualBox, with Mac OSx as host.

    Since I also travel a lot maintenance machinery installed (requires Windows) I would prefer a laptop instead of a desktop computer, so I decided on the following configuration.

    MacBook Pro laptop

    -2.9 Ghz Dual Core i7 Turbo boost upt 3.6 Ghz

    -8 GB 1600 Mhz, DDR3 RAM

    -Hard disk 1 TB Serial ATA 5400 RPM

    I don't have many accessories as I already have a brand new Kensington trackball mouse, if necessary I can use an external monitor of HDMI (26 inches) to my office.

    My questions are these.

    1 - is the support of configuration above virtualization?, I want to VirtualBox to do this, is it possible with the above specifications?

    2 Ethernet RJ45 connectivity is very important for me because I need it to connect to various industrial automats, not to mention I have Ethernet I / simulation software P in need of this port. I see that my Setup doesn't have an ethernet port, so how do I connect via ethernet? Is there an available Ethernet adapter? What possible limitations are there compared to an integrated?

    [3. can be Ethernet port be customized through the Mac OSx, customize I mean change the IP, DHCP/Static, the gateway IP address], netmask etc.. These settings can be changed?

    4. I would like to increase my RAM 16 GB (or more) I currently have 16 GB, in my view, it is essential for the execution of virtual systems.

    5. the HDMI can support a share whole 26 inch HD monitor?

    6 is better than Pro retina?, I will not be upgrading my laptop, once I have the RAM and the required hard disk.

    7. because this is my work computer, what is the approximate years Apple will support this laptop? Will take in charge the laptop be declined in the following years? I have an Ipad Gen 1, which is totally UN-useableas, it can not be upgraded. My laptop will end up like this in 5 years?

    Rest of the card OK for me, 1 TB look better virtual systems consume a lot of disk space, speed may not be a review I would leave the laptop running or in hibernation, I believe that extends the life expectancy of the hard drive. Battery life isn't a review I would leave my laptop plugged in all time.

    Please let know us what you think...

    Thank you

    1. Yes. But use Parallels instead of Virtual Box. The first is faster.
    2. There are two types of Ethernet cards. We use a USB 3.0 port and Thunderbolt, is used.
    3. Configurations can be configured manually. In most cases, it should be automatic.
    4. You can increase the RAM on the model 13 "as a custom configuration. The model 15 "comes with 16. GBs RAM is not extensible to the user.
    5. The HDMI port should be compatible with most of the ports to monitor.
    6. There is no model non-retine.
    7. Standard warranty is 1 year from the date of purchase. At any time within the first year, you can buy the extended warranty which adds another 2 years after the expiration of the standard warranty. All support including consultancies has a time delay. See registration Vintage and obsolete.

    Hello

    I think you mean the text stating "x of there matches", to the right of the box where you entered the search term.

    The first number ("x" in my example above) indicates the current entry highlighted on the page that matches the search phrase. If you use the upper and down arrows to navigate through the instances of this term on the page, you will see this number go up and down.

  • What does the symbol of a bolt of lightning on iPhone?

    I can't find a definitive answer anywhere: average what symbol of Flash on iPhone?

    Specifically, the battery of my iPhone is dead and sometimes the battery symbol appears WITH the lightning bolt and the symbol of battery above it with a small amount of red. If I jiggle the cable connection the lightning bolt disappears, then reappears, but the battery symbol is always present. So my question is, more precisely, what is the difference? That means the lightning? Why Apple makes so cryptic? Sometimes the lightning, sometimes not, that referred to as load? Both? Why do you then?

    You see, I don't know whether to shake the cable until the Flash is NOT visible, or whether it jiggle to make it visible. That means that the phone is charging. Why have a symbol that is subject to various interpretations but have no icon legend/reference anywhere a user can know what it means? Why have this symbol when it is just as easy to have plain text "charge" or "do not load"?

    If the bolt is present, it indicates that the unit is charging successfully. https://support.Apple.com/en-us/HT201569

  • What is the best audio format to import a CD?

    Dear people of the communities,

    What is the best format in terms of better sound quality for an import CD, regardless of the size of the file, just a pure sound quality?

    The goal is to save my music library CD and vinyl in a computer/drive and listening using a computer connected to a sound system 'Stereo' (not ' Surround', regular stereo) with speakers high quality stereo (L + R).

    So far, I've downloaded using a 320 kbps MP3 format. Listening to a CD quality is very poor.

    I use iTunes 10.7.x (as well as iTunes 12.x on a newer platform, but imports of CD I use version 10.7)

    All parameters are the following:

    Import using MP3 encoder =

    Parameters = custom

    Use the Error Correction = No.

    ---------------------------------------------

    Stereo BitRate = 320 Kbps

    VBR = No

    = 44,100 kHz sampling rate

    Channels = stereo

    Stereo mode = Normal

    Smart encoding = No

    Filter Freq below 10 Hz = No

    I think he wouldn't be WAV course, AIFF and Apple Lossless I know are both better quality, but using an Apple encoder can restrict what will be the player who is also important.

    Thank you

    Alon

    .

    Any lossless format will offer the best audio quality.  The available choices:

    • WAV is probably the most widely supported but it lacks the ability to incorporate metadata or illustrations, so while you can move the audio between different systems files as soon as you go outside iTunes you will lose all the artist / album / song information.
    • Apple Lossless (ALAC) is definitely the best choice in iTunes - he has the same metadata / support work such as MP3 or AAC and supports full 16/44.1 audio with file sizes about 65% of the equivalent WAV file
    • AIFF is very similar to the ALAC, except that (in the Variant used by iTunes), there is no lossless compression, so the file size will be larger

    The determining factor here will be where you intend to use the files - many other readers take in charge of the three options mentioned above, either natively or (for the ALAC and AIFF) using the appropriate plugins.  Unfortunately the lossless codec which has the broad support of all (FLAC) is not supported by iTunes.  There are, however, many utilities out there that can convert between ALAC and FLAC (and vice versa) if that proves necessary.
