In this thread you can post your requests for Lenovo ThinkPad T450s.
If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, or already upgraded Display and after that can't adjust screen brightness, then you can post your request in this thread.
For creating bios backup and to flash bios mod, you must use any SPI programmer (like CH341A programmer) and a SOIC8/SOP8 test clip!
Just dump your Bios using any SPI programmer (like CH341A programmer) and a SOIC8/SOP8 test clip, then post it in this thread or upload it to any fileserver and send me the link.
SOIC8/SOP8 test clip:
How to use it:
Also, you can search on YouTube a lot of guide for CH341a.
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.
