Lenovo K450 Upgrades

Hi, I want to upgrade my power supply to a 600w PSU to support a new graphics card. I would like to have either a GeForce gtx 750 or 760. Or maybe a r7 260X. How would I go about doing this since I heard the Lenovo IdeaCentre K450 can only support so high of a GPU. But I also heard that there was a way to bypass this and be able to use higher end GPUs. If I could bypass it, I would like to know how. I would appreciate some help in this matter, thanks. (Btw I purchased this in March 2014, so it has the new Haswell CPU) and since it's the new version, could it now take up to the geforce gtx 750?

hi JamesA95,
Welcome to Lenovo Community Forums!
According to this Tech specs
Your system sould support 8GB and this Laptop Has two Memory banks, so You should be able to do that RAM setup.
http://shop.lenovo.com/us/en/laptops/essential/g-s​eries/g580/#techspecs
Fro RAM I personally recommend this
http://images.crucial.com/upgrade/Lenovo-memory/Es​sential+%2F+Value+Line/Lenovo+G580-upgrades.html
Installing SSD This is ver doable.
have the SSD installed where the HDD is now and put the ssd on the Optical Drive slot using a Caddy for 2.5"
Your main Concern here is to Migrate the HDD content to the SSD and losing the Onekey REcovery Option in The Process.
Regards
Solid Cruver

  • HELP: Lenovo K450 Desktop Wireless LAN Problems?

    I recently bought a lenovo k450 desktop, first desktop i have bought, and ever had, ever since i've bought this desktop the Speed.net speeds are 1/2 of the speeds my laptop gives off. My Laptop gives a 54.0 Mbps Speed LAN connection, and my new desktop is giving off 36.0 Mbps , my friend has the same computer, and gets 48.0 Mbps , My desktop is a normal 3.00 Download, and always the same upload on both, 5.80 , my laptop is a normal 6.00-7.00ish download mostly, so if anyone knows how i can fix this i would greatly appreciate that. http://gyazo.com/845451ab21c05605e942081388eb9952 Heres a picture of my current LAN Speed 

    Hello James,
    thank you very much for your help.
    I did all the mentioned steps and first it seems that the WLan was working.
    It wasn´t as fast as expected, but I could surf in the internet.
    After another restart OSX asked me for the password of my router and then I got the old problems: Very very very very slow connection, broken connections and finnaly no connection via WLan.
    Do you - or anyone else - have another idea what I can do to fix this f.... problem?
    Thanks,

  • Lenovo T61p upgrading possibilities

    Hello dear Lenovo community people,
    I am new here and myself I'm an IT technician and I would like to do a few modifications to my Lenovo T61p. 
    First of all, my biggest plan was upgrading the processor, right now I have a Intel Core 2 Duo T7700 @ 2.4Ghz. I have read many posts and forums about going to Core 2 Extreme X9000 or Core 2 Duo T9300. My question is, are these upgrades possible and how much would they cost in today's used parts economy? Would there be any overheating issues considering the voltage and power they use?
    My second question is considering the RAM in my system. I have read that adding up to 8GB is possible, but Lenovo homepage says max is 4GB(which I have). Is it possible for me and how much would they cost in today's used parts economy? Would it be useful?
    My third question is about extra add-ons, my edition of this computer didn't come with a built-in SD-card slot, but instead had a built-in Smartcard slot, can I add an SD card slot somewhere(PCMCIA or anywhere else besides USB)?
    Also I don't have the firewire port, but instead it has just a black plastic in front of it. Can I add a firewire port there?
    Are there also any 3G possibilities on my system, besides 3G USB?
    My fourth question is about the HDD, what is the maximum a T61p will support, right now I have a stock 100GB HDD, I was planning on putting a 1TB in, since it fits in there. Is this possible?
    Also, what kind of motherboard do I have? I heard the penryn is newer compared to a merom and has more possibilities. How to determine, which model I have?
    My last question is considering the TrackPoint, I have the old-fashioned TrackPoint, which the old T23 had(http://blog.codinghorror.com/content/images/uploads/2006/05/6a0120a85dcdae970b0120a86d647f970b-pi.jp... so I really want to upgrade to this new one(http://www.vath.co/images/IBM%20Trackpoint%20SOFTDOME%20165.jpg). Is it possible and will it fit?
    Are all these choices useful, considering I do lots of work, install a lot and do med-heavy gaming(CS: GO, old classics, some new ones etc.)?
    I am also wondering; which Windows suits me best, right now I have Windows7 Home Premium, what is the next best thing, Enterprise or Ultimate, or stick with Home Premium, what are the differences in perofrmance? Should I go to Windows 8 or 8.1, maybe 9 or 10???

  • Lenovo Care upgrade can't install Client Security update.

    Hi !
    Laptop is 3000N200 (0769-BAG) Upgraded to Windows XP.
    Since a couple of weeks, when I launch Lenovo Care assitant and look at upgrades for my system, it finds Client Security Solution Version 8.2 but the installation finished immediatelly and said that it was not installed. I don't know why, I can't see a log file nor an error message. If I launch the assistant again, it finds the same update availlable again...
    What is wrong with this ? And how can I fix the problem ?
    TIA ! 

    You should check out my detailed post in the following thread:
    http://forums.lenovo.com/lnv/board/message?board.id=N_Series_Lenovo_3000&message.id=5649
    However, I'll summarise.
    a) It seems that the system update application tries to load version 8.2 (of the Client Security Solution) on top of version 8.0
    b) It seems that you cannot go directly from 8.0 to 8.2; you [manually] have to go via 8.1 which is available here (vista/xp):
    http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-69128
    http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-69733
    Of relevance to diagnosis was that you really need to do a manual install to actually see the error message rather than just have the install fail silently. Overall, however, it was reading the various related web pages that yielded the needed information (see the post I referenced above for the detailed information).
    Lastly, when doing the manual installs I did receive an additional error message related to the version of finger-print software I had loaded. I now believe that this was a red herring, but it did lead me on a wild goose-chase (read my other post for the gory details).
     Good luck and post your experiences back here!
    George.

  • K450 upgrading to GTX 670

    I have a K450 which came with a GTX 650 installed. I have a GTX 670 which I'd rather use.
    To get around the K450's weak PSU, I installed a FSP Booster X5 (which is a secondary PSU which fits in the 5.25 bay and provides additional PCI-e plugs). The secondary PSU works fine- I'm even using it now for the original GTX 650.
    However, when I plug in my GTX 670, things go awry. The system powers on, and boots. The new GTX 670's fan runs, and it appears to be fine.
    However, there's no display. Not during boot, not once the OS has booted. No BIOS, no post, nothing. I literally get no signal. Switching to onboard video doesn't work either. I can select in BIOS to only use onboard graphics, but as soon as I put in the GTX 670, even the onboard doesn't display.
    I'm wondering if there may be some incompatibility in the BIOS with this GPU, or if a BIOS upgrade is even possible. I've read online that the default K450 supports up to GTX 660s, but I assumed that was a limitation of the PSU and not something else. Since the PSU isn't the issue here, I'm a t a loss what to try next.

    I'm having the same exact problem trying to install a RADEON.
    The power supply works but the only card recognized by the bios is the gt 650
    Did you ever resolve this?
    I had reason to believe my 670 was bad, so I put my tests on hold until I could afford another. But getting another wont help, I'd rather not spend the money.
    It would really too bad if the 650 is the *only* card you can use on this box...

  • Lenovo G505s upgrade

    Hi Guys
    was wondering if you can help me, i bought a Lenovo G505s about 9 months ago 8gb ram, 1tb hhd, amd 7640g, AMD a8 4500m could i upgrade this to a A10 and if so what one, im at work atm so i can give you any more details.
    more info im doing this so i can run League of Legends abit better atm i only get about 40 - 60 fps on that and 60 at low.

    hi HomebredTripod,
    Welcome to the Lenovo Forums.
    As per this G505s tech specs and from the spare parts image below, the Lenovo G505s can go as much as AMD A10-5750M APU.
    - Link to picture
    The upgrade is possible but I don't think it's worth the money that you'll spend on the new CPU as it's a bit expensive and the improvement is not that great.
    - A8-4500M benchmark
    - A10-5750M benchmark (see price here)
    IMO, I think it will be much better if you get a new system with a dedicated graphics to boost the FPS while playing games (you can either keep your old Lenovo or sell it to addup to the cost of your new gaming rig).

    Hi Pheonix...
    Intel HD graphics is integrated with the CPU, a dedicated graphics chip would need to be soldered to the main-board.
    If you swap the CPU with a more powerful one you probably need to install a larger heat-sink as well.
    In short... upgrading is not very practical, may think of selling your B560 and buy a more powerful laptop.
    good Luck... Zehn

  • T410s display port no longer works after lenovo / win7 upgrade

    Arrggh...  I have a Dell u2711h monitor that i connected to my t410s via display port.   It worked fine until i did a lenovo driver updateand windows 7 update.   Now, it just goes into powersaving mode with the display port.   I backed out the windows7 updates, went back to a windows restore point from when i knew the dp worked, uinstalled / reinstalled the lenovo drivers for nvidia nvs 3100m optimus, audio, etc. 
    The HDMI cable works, the monitor works with display port off of another PC, but no longer on my t410s.   Anybody have any ideas?   I spent a lot of money getting a big monitor with a high resolution trhough dp, but now i can't use it.  Very fustrating.   
    Any ideas?

    Hi dft410s,
    Please try in BIOS to isolate hardware/software issue. If problem remains, please contact local lenovo for machine inspection

  • Lenovo H230 - upgrade from Windows 7 Home Premium to Professional

    I would like to put Professional on my H230 in such a way as to have it in the RECOVERY PARTITION so I will be able to RECOVER to that version.  I do not believe an INSTALL will allow that.
    How do I install to the RECOVERY PARTITION?  so it will be the RECOVERY version?

    Well, I'm embarrassed to admit I rather "jumped the gun" on this one ... having written and posted my query I thought I'd see if a Restart would help ... it did!! Turns out I am now satisfactorily upgraded to Pro.
    Sorry if I have wasted anyone's time and ... if you're experiencing a similar problem ... I'd advise you go for a Restart before panicking ... like me!!
