The flashing procedure include two steps:
1. Flash main system bios.
2. Flash EC firmware.
When my first CPU fan on Y500 is broke i replaced it on something compatible (non-original) and planned to replace it later on original. Since that time happened a lot things, but i still using that non-original fan. But i did some research and here is what i founded:
1. Forcecon (marked as FCN on fan)
DFS5413005MH0T-FC1C (5V - 0.5A)
Spotted in: Y400, Y500.
2. Asia Vital Components (marked as AVC on fan)
BNTA0612R5H-P007 (5V - 0.5A)
Spotted in: Y410p, Y500, Y510p.
3. Sunon (marked as SUNON MagLev on fan)
MG60120V1-C230-S99 (5V - 2.25W (0.45A))
Spotted in: Y410p, Y500.
So, which to choose? Any recomendation? Maybe there also unexpected way (completely diffirent fan from another company for another laptop)?
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
Recently obtained myself a bricked Y410P after undervolting my CPU, using svl7's bios mod on TechInferno. If you only take one thing away from this post, it should be the fact that
NEVER SHOULD YOU EVER UNDERVOLT A LAPTOP CPU FROM A MODDED BIOS. Hindsight is never 20/20.
Anyways, back to topic!
I went and purchased my self one of these, in hopes of to re-program my sad bios. So far no good.
I am wondering if anyone out there have had any success with this approach. Please share your journey here!
