  • Increase the system video card!

    Hey guys...

    I have a dell laptop ((E6510))

    And I have 8 GB of ram

    but in my screen resolution > avancΘs > I have only 64 Mp built in video card

    and 0 MP system video card...

    is it possible to increase the video card? or use my Rams to increase?

    There is no way to change the RAM allocation, no.  These systems come with the option of hybrid video (Intel + AMD or Intel + nVidia).  To perform this upgrade, however, the jury of the entire system must be changed, as well as the heat sink (figure $250 or more in parts + $100 in labor).

    The upgrade will void your warranty, if it is a review.

    You cannot change the height of the horizontal blade in the system palette. You can use one of the modern palette that Mike has suggested, or you can use ActiveX ProgressBar or ProgressBar .NET if you run Windows. If you want to search for the latter, the forum as there are has examples.

  • Your system is low on virtual memory. Windows is increasing the size of your virtual memory paging file. This process may be denied requests for some applications.

    When I start my laptop I get "your system is low on virtual memory. Windows is increasing the size of your virtual memory paging file. This process may be denied requests for some applications. "and my laptop takes forever or does not open my programs. any help? Thank you.

    less than low disk space,

    What seems to be the case, it's that your windows is having a hard time resize its file for virtual memory.

    my suggestion is to remove "auto" at that time, and then set a custom format.

    I recommend that you set the initial size of 2 and max at 1152.

    Here's how to put a link:

  • Is there a way to increase the size of aka msconfig window System Configuration?

    In windows 95 and 98, it was easy to increase the size of the System Configuration window, and there even a beautiful button "expand".

    It was possible to use the Win9X msconfig in XP, but it doesn't seem to work in Vista Home premium 64. Is it possible to increase the size of the window? Can I change a setting of registry or something in the .exe itself?

    I'm bored of ResEdit on old Macs.

  • How can I increase the recovery of Windows system restore drive 7?

    I have windows 7 ultimate and I read someone's question on the increase in the recovery of the system and I was wondering how to find it on my laptop and desktop? Because if I can and have better if restore points I ever need to go back which would help in the right now with my laptop, that my restore points back only 7 days. Which is weird, this laptop has been used longer than 7 days and I for 2 days.

    And it is the same for windows 7 Home premium? So I could show my father and my brother as well :)
    Thanks Cortana :)

    System Restore saves as many restore points as he shared.  When the allocated space fills, more older restore points are deleted to make room for the new.

    Although SR in Windows 7 is much better than XP, I would always go back much more than a week.  Windows 7 warn you: on the first screen of the system restore, you will notice a link that says "search for affected programs.  Click here to get an idea of what problems might arise if you go ahead with the restoration.

    Also, the list of restore points that shows initially cannot be completed.  Check the box "Show more restore points" to see the rest of them.

    Here's how to adjust the space allocated to the restoration of the system (all Win 7 versions): http://windows.microsoft.com/en-us/windows7/how-much-disk-space-does-system-restore-require

    Here are answers to some common questions about the system restore.

    Remember, the system restore saves its restore points on the same drive that is "protection". If this disc fails, both your system AND your backup disappeared.  Best practice would be to save the backups on an external support.

    If you want to stay with built-in tools, see, for example:

  • How to increase the amount of memory to the host system?

    Hello gentlemen,

    I am new to VMware ESXi 5, and I want to know how to increase the amount of memory for the host system?

    I saw in the Configuration menu of the host, my ESXi host has only 77.3 MB. I think it's wrong, it's too little amount of memory dedicated to the host system. It is not a (Properties) button after I was able to change the amount of memory host system.

    Please, be so kind, help me!

    Thanks in advance!

    Welcome to the community,

    where do you see this amount of memory?

    The total amount of memory installed on the host can be seen in the summary, tab (resources) with the host country is selected in the inventory.

  • Increase the performance of MAC with the SSD upgrade

    I have a 21.5-inch iMac model 14.1 (end 2013) with 8 GB of memory and a 1 TB drive. On this, I use some applications in memory such as Adobe CS 5.5 and VMWare Fusion 8.1.1. I have Applecare on the machine until September 2017. I often find myself running out of memory. My goto solution would be to increase the memory and replace the hard drive with an SSD. I fear, however, that this cancels my Applecare. My research indicates that while that frowned upon, I can upgrade my memory and keep my Applecare as long as it is done by an authorized by Apple, but if I do the SSD I'm out of luck for the installed components. My thought is that I can get an external SSD and move the ' WIndows 10' VM (s), as well as expand and move the swapfiles for the SSD system.»

    My questions are am I right about the Applecare and warranty and I plan to use an external SSD to accelerate performance and ease the work of memory constraints?

    I have f

    I have a Macbook Air in 2010 and also a 2008 iMac - both with only 4 GB of memory (you have twice as much), both running El Capitan and the two with SSD - and perform very well. The 2008 iMac used to have a rotating disc which has recently failed, with the replacement of SSD, it is a remarkable transformation with the new SSD, it seems very quickly for me. Both have Photoshop CS4, which is not used much more, but they run this software very well, as well as MS Office 2011 and other programs such as Mail, Safari, Firefox, etc. (Firefox + Photoshop together put a noticeable load on machines, in fact, but while I sometimes hear the fans come on the Macbook Air, it maintains not up very well) No slowdown) You'll be in great shape with a SSD for your newer computer. These old machines that I use have Core 2 Duo CPUs, chips relatively slow, but they seem very quickly with the SSD.

    You will need to check with Apple directly on your AppleCare and so that would be affected. I don't know that anyone is not Apple should trust this question.

  • Extend an AirPort Extreme with a Terminal AirPort Express increasing the number of users?

    I have an AirPort Extreme 2 years ago. Based on the technical page of the product, the router can theoretically connect up to 50 users. That's more than enough if used at home.

    However, I intend to deploy a network of airports in our new office building and we have more or less 50 employees. Because everyone has a smartphone that it needs to connect, I try to at least 100 users/devices. Which includes all the network printers. Obviously, an AirPort Extreme is not enough. Another thing, I have considered is that the office building is 2 floors and all the walls are made of concrete, which means the distribution of the wifi signals is affected.

    I thought to extend an AirPort extreme with 3 more AirPort Expressare (mobile network). It's 2 APs on each floor. That should solve the problem of distribution wifi. I'm not sure the first problem - 100 or more devices into a single network.

    So extending an AirPort Extreme with 3 more AirPort Expressare (making a roaming network with 4 access points) increases the number of potential users of 50 to 200 (assuming that each access point can connect to 50 users)?

    In theory, Yes.  But you must take this specification of 50 users with a grain of salt.  Once there are 20-25 users on the same airport access point, things will slow down significantly. The system will operate as of cold molasses with up to 50 users on the same access point.

    Quite frankly, in a business application, you need a software router. Apple routers are designed for home use.

    Another way to say the same thing, is that Apple does not routers Apple at the Apple Store. Who could tell more than anything whatsoever about the suitability of the products in your proposed network.

    My advice would be to get an IT professional in and review your needs... before you move further.

  • I am looking for a solution Server (with Te css) for the fact that Firefox uses the system DPI settings, which makes my site look (too) big.

    My site appears much too big in firefox. And I want all browsers to view my site properly.
    I know that there are settings wihtin firefox that fix this problem. But I'm looking for a solution on server side, so that visitors to my site must not be disturbed by changing their settings.

    You may need to change your site as soon as 30 Chrome and IE 11 will also use the system DPI setting (like Firefox does now).

    Possible solution:

    • Type of topic: config in the Firefox address bar and hit the Enter key.
    • If the warning that this might void your warranty , click I'll be careful, I promised.
    • Search for layout.css.devPixelsPerPx

    • Double-click layout.css.devPixelsPerPx to edit its value. The default value is - 1.0 in Firefox 22 and above. Change it to 1.0 to run as in previous versions of Firefox.

    If necessary, further adjust the value of 0.1 or 0.05. Values between 1.0 and around 0.5 to reduce the size of the elements. Use a value greater than 1.0 to increase the size. For example, a value of 1.25 will increase the font size of the 125% to account for the default DPI setting in Windows 8. Check the value that you enter. Definition of a value that is too small will take everything away and too high will explode things.

    If the web pages should always be adjusted so you can watch the extension Default FullZoom Level or NoSquint .

    To adjust the font size for the user interface, you can use the extension of theme font & size changer .
