HP EliteBook 8440p: memory modules RAM that actually work for HP EliteBook 8440p?

Hi everyone again. I scoured these forums and others and can't find a definitive answer to the upgrade of my RAM memory.

My system:

HP EliteBook 8440p

2.8 GHz Intel Core i7 M640

Professional Win7 64 bit

133 MHz bus clock

BIOS: HP 68ccu, worm. F.11 (2010)

Dual core, hyper-threaded (4)

(?) Mobile Intel QM57 chipset

According to Belarc Advisor, I currently have a 4MB of RAM Samsung under the keyboard module. The second location is empty.  First of all, more memory RAM is not sold in the UK? I know that the computer is capable of 8 GB and the Kingston modules, I just tried to install were 4GB each.  Sticks of Kingston are 8 GB (2 x 4), PC3-10600, CL9, 1.5V, 204 pins SODIMM modules and they do NOT work on this laptop even if they should.

Has anyone found the secret of exactly which modules memory will work with this specific model of laptop? It is issues of density? Problems of tension? Am I missing a driver. I have to sing the thing while I install memory?

Seriously, any help at all will be appreciated.

Hello:

Please read this thread, and I posted the memory you need to NewEgg if you live in the USA/Canada.

The 8440p uses the same memory as the 6550 b.

  • fraud, claiming that he worked for microsoft,

    I gave my email address to a fraud, claiming that he works for microsoft, should I change my email address?

    I don't know there is nothing much he can do with just an e-mail address with the exception of spam to your Inbox with unwanted or of links to viruses to hack into your account. If you have a feeling of insecurity, then create a password stronger, make sure your security options are configured so that you can reset your password with another email address or phone number, etc.. If your profile contains too much personal information, then you can clean it up a bit. E-mail addresses are supposed to have some very basic information. Don't open strange e-mail and do not click on email links even if it appears to come from Microsoft (the old trick in the book).

    Note: Most of the electronic mail services allowing you block e-mail from certain senders

  • Care module RAM that requires an upgrade to a Satellite A100-014

    The A100-014 that I has two RAM slots (dual mode).
    There is a 1024 MB DDR2 PC2 4300 (266 MHz) in slot 1.

    I would use the slot 2 for a RAM module that I got from my old Asus computer which is a 512 MB PC2 4200 s. You think it's compatible?

    Thanks a lot for your valuable advice in advance.

    Hi pierfrancesco,.

    I see that my clue has been useful for you with this screwdriver and etc...
    So, I can give you a second suggestion? :)
    It would be preferable to use a similar memorymodule due to compatibility issues. OK, no one said it wouldn't work, but it is possible that the different timings are some question about the stability of your system. So, try if it works. If Yes, then try for a few days, and if you haven´t then after these days of problems with the stability of your system, then you know everythings fine.

    Just one more time: Don t worry, your machine won´t get broken if you insert the second module. If it works, doesn´t, then the module would not be recognized ot some...

  • Instructions to remove the search engine do not work, the "delete" button remains grayed out check marks independently. Is there another way that actually works?

    The Firefox Support instructions below do not work in version 36. The button 'delete' is never gray State asset once the unwanted/s search engine are checked for removal. I tried one at a time and in groups, it does everything just as they suggest below.

    Delete a search engine

    You can remove search engines, that you don't need by performing the following steps on the search bar in the toolbar or on the page tab.

       Click the search engine icon and select Manage Search Engines... to open the search engines manager.
       To remove a search engine, select it from the list, and click Remove.
    

    If you accidentally delete a default search engine, click on restore default values to recover the default search engines.

       If you accidentally delete a search engine that you installed, you must re-install it.
    

    I found the solution, the surprisingly simple. Thanks to everyone for trying, but against all the recommendations after a new analysis of malware, virus and upgrade to the latest version released on March 5, 2015... Here is the fix:

    Left click on the dropdown search button, then left click on the "change search settings." Ignore completely the checkboxes as suggested by Mozilla. The text of the search engine you want to delete to highlight in blue in the Middle, click on the grey Out button below should become active. The only function of the boxes by the search engine will make them visible or not when using the search box in Firefox. The solutions proposed by others seems logical, but I learned more than 4 decades as a technician in computer science, opt for the simple solution first. Thank you all for your suggestions, this fix works for versions 36 and 36.0.01on Windows 7. I guess it should work for other OS also.

  • Is a tool from microsoft that checks for viruses that actually works

    I tried to use mrt.exe and the new scanner from microsoft that is the safety scanner and I used Security essentials but was not able to find the virus on my computer and when I try to manually search on the appdata and the virus was there. Guys can you like recommend me some of your tools from microsoft that can check for the presence of virus, it will be really meant a lot

    I get my infected computer all the time on purpose (practice remove infections) and I can tell you right now with100% certainty that Microsoft's tools are often too weak to detect even some of more common conditions of system and subsequently will not be able to delete them.  I don't even use Microsoft tools more for anything - I don't have time to waste.

    'Fair' note Microsoft tools and but lack many things that other applications will be prevent, detect and resolve.  Some applications are more aggressive and quarantine (effectively delete) critical XP system files, resulting in a scenario without boot (it is usually because definitions are out of date) so that makes these situations an error to the user (not the fault of the tool).

    No single analytical tool seems to know everything, so it is prudent to use more than one.

    Microsoft is not in cases of prevention, detection or removal of malware - that aren't their specialty.  There are other companies where the removal, prevention and detection of malware is their specialty and that's all they do all day long.

    Why are we expect or ask Microsoft to surpass in the areas where it's not their job?

    When Microsoft tools fail or if you even suspect that they might have missed something, I always start with the free MBAM and SAS versions because they are free, install any boot on your computer and they uninstall cleanly if ever there is a need to remove them (there is no trace).

    Just start with MBAM and SAS first, and you will not waste any time trying things that might work maybe sometimes from time to time.

  • Hot spots that actually work?

    I am frustrated beyond here. I tried to get a hotspot question slide to work for more than an hour now. (Can you say, "Loss of productivity"?) Tried everything logic. Made of the hot spot larger, smaller, deleted the slide and recreated, disabled compression project, added/subtracted other hot spots, checked my hotspot is marked as the hot spot 'Correct', enabled the "show in the pointer", added images different and tried fused/not fused with background and other things I don't know I don't forget. Help! I need to work for my small business. It's something simple I forget here? Or they simply do not work?

    Received a response from my Bug report:

    Hi Brian

    It is a known with Captivate 3 bug seen with Fp 10. Please note that this works if you preview in the browser and also view the published content. The solution is to roll back to Fp 9.

  • They contacted me by phone, saying that they work for Microsoft and must connect to my pc.

    Anyone has any experience with the aforementioned company? They contacted me by phone, saying that they are working for Microsoft. When I asked the guy on the phone he becomes condescending, flippant and unprofessional, and I sopped the call and, above all, its connection to my pc. Is that bana fide company? Any comment please?

    Fake phone calls to technical support

    It is a common scam. Do not let them give any info, do not give access to your PC, not give them all the money and do not go to all the websites that they suggest. One moment.

    Microsoft does ever not requested for telephone calls of support or security.

  • Satellite M70 - 160 upgrade memory module RAM

    Hey, guys... I am the proud owner of a Satellite M70-160.
    I am considering upgrading my ram memory (I have 512 ddr2 at 533 mhz) and I woul like an another 512 and I have 2 problems. The first is that the memories of toshiba is the best? I mean they offer 2 types of memory ddr2 512 PA3412U - 2M 51 and PA3412U - 1 M 51.

    The second question is "can I use other brands of memory ddr2 512 RAM sticks?" I mean they have to be exactly the same as that which is inside the laptop? Because I have seen other brands than ddr2 512 to 50% of the Toshiba offer those... In fact someone at the main dealer of Toshiba in Romania offered me another brand, SILICONE - something... (or something like that).

    Thank you very much!

    Hello

    I think that the two bars of Toshiba offer the same performance, because they are the two PC2-4300. You should also be able to use other modules of the same type. They are simply not tested by Toshiba.

    Good bye

  • Will there be security of Microsoft (or any other company) programs that actually work?

    I'm currently under Windows Vista Home Premium, Service Pack 2 on a Dell Studio 450, 64 bit OS, 4 GB of RAM.  For security, I have the full licensed version of McAfee (including firewalls, anti-Spam, Phishing, & scanning in real time, by email, online, etc.).  In addition to this, I also have Windows Firewall, Windows Defender, and a program of detection of advertising.  Everything I use in full mode and take full advantage of the guarantee that they are supposed to offer.

    So you can imagine my surprise when, after having problems with my monitor of all things, I put a manual scan, which detected a Trojan horse and two viruses.  I checked the log files, nothing has been detected up to me defining manual tests.  No attempt had even been "noticed".  After seeing the results, I went and double checked to make sure that everything was on and functional... that they were all.

    I took care of the intrusions and then did a little research on them.  Everything that I could find & learned was that it was more trouble than the threats, they were all low-risk to the computer and my network.  A site even quoted the Trojan horse as being the lowest of the Totem virus!

    It is rather a question of two parts: 1. What is the purpose using programs all the time, and still less pay for them, if they don't work?  If this small 'GNAT' of a virus could do on my machine, what on Earth will keep a virus really high-risk to become?  2. has someone at - he found a program that does not really work to keep stuff on your device?
    I would like any input, advice or suggestions that you have!
    Thanks for reading!

    The problem that have security software providers, is that they see a virus before they work how to detect and remove. There is still a window of opportunity for the virus before that definition updates are shipped out. If the component in real time of the anti-virus program can fail, but it is picked up by a scan a few days later. Most of the antivirus programs include components that examines what a program is to try to detect anything suspicious. But it is not foolproof either.

    There are steps to take to protect yourself from such that

    • Run as standard user and not an administrator. This can make it more difficult to install malware.
    • Do not install a program if you didn't not go get her. For example, if you go to a site and it tells you you need to install something to view the content
    • Make sure that Microsoft updates are applied as soon as possible

  • Does anyone know of a version of windows defender that actually works? It doesn't seem to work at all, no matter what you do.

    I have an icon and the laptop says it's there, but it is impossible to turn on - it doesn't seem to work.  Windows Defender seems unnecessary, can we just use Microsoft Security essentials for 8.1 who actually seemed to work.

    Windows Defender is disabled on Win 8 when third-party antimalware software programs are installed on 8 to win.

    Have you deleted any third party antimalware program, run the appropriate removal utility (McAfee removal tool, Norton Removal Tool, etc.) and then the computer restarted?

  • Audio device which is marked by default isn't the one that actually works!

    In the dialog box Windows 7 called 'Sound', there are 4 tabs: reading > recording > sounds > Communications.

    If I go to 'Record', I see a list of devices - mainly the microphones where that I want to use (high definition USB microphone) is marked as the default value.

    Problem is that when I entered the device, nothing is heard or recorded. I think it's the device listed depending on who is really active (since the indicators of level in the dialog box).

    If I delete the 'next listed device' (Webcam C210) nothing works.

    How can I get the device that I want to be the default working?
