Re: T470 bios needed
Hi guys,
I have a laptop t470, model 20HE with i7-6700u CPU. The current version of BIOS is N1QET72U (1.47u), which is custom version of BIOS not possible to update. I have already tried the BIOS file from post #4 in this thread, but unfortunately didn't work.
Could anybody share the BIOS for t470 20HE with CPU i7-6700u, so I could try to flash it?
thx in advance for any advice...

Re: Lenovo ThinkPad T470s BIOS
Hi Thx a lot, but it is not working ... I flash the bios, but when I plug the PSU, the power button light up for a moment and stays dead ... not possible to power up. From time to time the cooling fan turns on for a moment and then turns off. All BIOS files do the same behavior. I have used the NeoProgrammer with Ch341a and XGecu TL866II plus ... same result. Am I doing something wrong? Hopefully, I haven't destroyed the motherboard
Or should I desolder the bios chip for programming?...Last edited by dopson; 10-05-2022, 08:21 AM.Leave a comment:
