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
I got the exp gdc beast 8.5 got all the connections right... laptop boots up... fans turn on the gpu.... device manager detects gtx 1060 with a “ ! “ in a yellow triangle. Now what to do.... i tried to do the bios mod.... but realised that i have 3.07 version.
1 is there any way to get this done without the mod??
2 if mod is the only way... kindly help me with step by step instruction in laymans terms... i m not a techy... so i might not understand technical terms.... altho i am interested... but learning yet. Please help.
In this thread you can post your requests for Lenovo Y50-70, Lenovo Y70-70, Lenovo Z50-70, Lenovo Z70-70, Lenovo G50-70, Lenovo G70-70.
If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, or unlocked vbios for overclock NVIDIA card, then you can post your request in this thread. Also, if you have a problem with fan pulsating/clicking on any modified bios then you can post your request in this thread.
The flashing procedure include two steps:
1. Flash main system bios.
2. Flash EC firmware.
The computer I used was '' Lenovo Y510P ''. There is a '' Nvidia GT755M [SLI] '' as a display card. I have tried both ways of downloading the video card driver from both GeForce Experience and Nvidia driver site. Both kinds of graphics cards are starting to update. Later, the 'graphic driver is installed' part of the screen goes and never comes again. I can not enter Windows when I turn off the computer. I have to take format from scratch.
After formatting, Windows automatically loads a graphics card driver in 2017, trying to update the driver again, it stays black on the screen again. I have to format again.
With DDU (Display Driver Uninstaller) program, I deleted the old video card driver and updated it again. But I met the same problem.
I communicated with Nvidia and stated that I had such a problem. They asked me not to install the 388.13 video card driver. That graphics card driver has been loaded without any problems. But I have the same problem with all the video card drivers out there.
NOTE: This problem only happens on Windows 10. I can update the display board without any problems in operating systems like Windows 8,8.1.
NOTE: I have been having this problem for about 2 months, before I could update my display card in Windows 10 without a problem.
The driver I am currently using is: 388.13
