Help! Lenovo z41-70 + MSI NVidia GTX 970, Windows 10, Internal LCD [Shanghai]

Recommended Posts

Current Status: HELP NEEDED!

  • mPCIe port actually micro PCIe, not sure if I can convert it or if this is a lost cause





Part 1: Open the laptop

Part 2: Remove the WiFi card

Part 3: Connect the extender (or the bPlus board if you're not using the extender)

Part 4: Connect the graphics card and PSU

Part 5: Software and integration


Part 1: Opening the laptop

  1. Unplug your laptop and power it down. Place it upside-down in front of you so that the labels are upright. 
  2. Starting from the top left, unscrew the screws around the outside of the case.
  3. Move to the three on the inside, saving the middle one for last.
  4. Note that the middle screw will not unscrew all the way. Just unscrew it until it's loose; you'll push it out from the other side in a moment.
  5. Insert a long, thin object such as an unbent paperclip into the indicated screw holes. This will pop the keyboard off the front of the laptop.
  6. Gently pull up the rest of the keyboard.
  7. The keyboard will be connected by two wires. You can choose to disconnect these, but leaving them attached is fine and less annoying.
  8. Lift the keyboard out of the way to find the middle hole with the screw that doesn't unscrew all the way. 
  9. Using your long object, poke the screw out.
  10. At this point, the disk drive (or placeholder if you don't have one) will be loose, so if you're going to remove it (like I did), feel free to slide it out.
  11. Starting from the disk drive hole or a corner, pull the cover off the back of the laptop. You will hear it click as it goes.


Part 2: Removing the WiFi card

  1. Now that the laptop is open, locate the mPCIe slot.
  2. Gently disconnect the two antenna wires by pulling them out at their heads. If you want to preserve the internal wireless card for later use, be very careful with this step; I accidentally crushed one of the wire terminals without even trying.
  3. Remove the screw which holds the card in place. Unfortunately, the people at Lenovo made this screw out of reconstituted sewage instead of metal, so chances are it will become 100% stripped the moment you touch it.

Help I need right now:

Can I convert my cables or am I done for? (see reply below for image)

These small wireless adapters have tiny (basically no) antennas, so unless you have no walls between your router and laptop, they will yield shitty speeds. I have personally tried one and had a network speed drop of 90% with 2 walls separating my laptop from the router. I suggest you buy one with proper antennas, those will work much better. I use an ASUS USB-N14 and I'm able to max out my internet just like with the original mPCIe wifi card.

I actually managed to the wireless dongle working right - the issue was just drivers, not technical limitations. I am still totally stumped by this stripped screw though!! I took my laptop to some lovely friends with a lot of tools and even after we tried everything we had, we still couldn't get a hold on it.

Long overdue update: I managed to get the stripped screw out, but now I have a worse problem. It seems that my mPCIe port isn't an mPCIe port; it's a micro PCIe port.


Can this be converted? or do I need to give up?

Yo lappytoppins has a m.2 port there...

Specifically, the m.2 key e

This is what you need, the v4.1 with the m.2 adapter.

Oh shit, well that makes a lot more sense. Guess I'll sell the one I got and use the proceeds to buy the correct one. Thanks!

      I want to show you my new project.
      I bought my laptop about 5 years ago.  It was never speed deamon, but for every day use, it was enough to me.
      Its specification:
      Intel i7-4700MQ
      Nvidia GeForce GT745M
      16GB RAM
      512 SSD Adata SU800

      Yesterday I bought Witcher 3. Of course on 1080p it's impossible to play, because of about 10fps
      So I make a decision to buy external grahpic card.
      I choose GTX970 and now I am looking for occasion to buy it.
      I've already bought EXP GDC v8.4d mPCI-E. It is used and cost about 30$.

      I will use ATX PSU to supply graphic card, because I have old desktop PSU at home.
      My plan:
      1) unlock bios
      2) buy GTX 970
      3) enjoy Witcher 3!
      BTW I try to cool down my laptop, so I replaced thermal paste to Kryonout Thermal Grizzly and make some tests. Temperatures and fps are on screenshots.
      1) laptop on table, playing GTA V 1080p

      - first minute (GPU core 1045MHz)

      -after some time, because of high temperature and GPU throlttling (GPU core drop down even to 400MHz)

      2) with thermalpad Glacier NC400 SilentiumPC

      - 30 minute and longer (GPU core drop to about 900MHz)
      3) without down case of laptop (like on picture with thermal paste) on thermalpad.
      Here laptop never drops down MHz and max temp are about 72 Celsius degrees.

      Bacause of that I bought second down case for my laptop and I will cut there additional holes.
      I will describe next step when I get all stuff I need!

      Hi folks,
        Greetings from Brazil!  Not sure I'm posting in the right place, but I have a question:  how do I find out the brand and model of my BIOS chip without having to open my laptop?  I can't find this information anywhere.  Been searching for days... I have a Lenovo Ideapad 300-15ISK 80RS (motherboard Paris 5A8).  Thanks a lot for your time and help! I really appreciate it!   Best regards,   JC.

      I have always been a big fan of Windows 7. I have 4 Media PCs throughout my house and a laptop. I have recently updated some of them to Windows 10 Pro. I have tried everything to get them talking on my LAN. I cannot share files anymore. They all ping, but are missing in the network folder. Thank God for Plex. Any advice?

      Hi guys,
      I'm sorry for making another thread just for this but I really wanted to pick your brains on this!
      I have an m15x with a 770m running windows 7 and everything works. Rock. Solid. I'm pretty happy with it. Since windows 7 is on it's way out, I would like to upgrade to windows 10. Now I've looked into it before and had a really hard time getting the 770m to behave nicely and had all these issues with green/yellow/pink screens and I remember it being a miracle I got it to work on 7 as good as it does.
      My question is how well does the 970m install vs the 770m - particularly on windows 10? I would buy it in a heartbeat if it makes the install less tedious with the colored screens and all that. Especially if all the functions work on it! I have been searching the internet and I cannot find nearly as many problems with the 970m as I could with the 770m, or am I just  not looking in the right places?
      Thanks a million!

      Hi, I'm having problems trying to connect a GTX 750 Ti to my Lenovo T420 using the dock EXP GDC Beast (express card version).
      My laptop: Lenovo T420
      RAM: 8GB DDR3
      CPU: Intel Core i5 2520M
      GPU: Intel HD Graphics 3000
      My problem is: if I plug the express card and I turn on the laptop it doesn't boot up and the screen becomes horrible, with coloured pixels and a sound like "bip-bip".
      If I try plugging the express card when the laptop is already turned on it sees the gpu, but if try installing the drivers I have to apply the modifies restarting the computer.
      I hope you understood my problem (I don't speak English very well).
      Please help me, It's making me crazy!
      EDIT: I didn't say that if I plug the express card when the pc is already turned on, in the device menager there is "Error 12" on the gtx 750 ti
