Write your Device Model and Serial Number.
What do you mean by "Laptop start but unable to boot to Windows or Enter Setup" is the device has a Password? or it stuck on logo?

Lenovo A475 Error 0285 TPM initialization failure

Hi everybody,
I hope that I don't make a mistake by creating this thread : if so, I'm sorry...
I had problem with a lenovo A475 model 20KM with AMD PRO A12.
After an update, it doesn't boot and I have a sound error code : 0285 TCG compliant functionality related error (might be the TPM initialization failure) and the Lenovo PC Diagnostics Apps indicates to replace the motherboard ...
The screen stays black, impossible to enter the bios or to do anything else.
Do you think it will be possible to fix it and how : I don't find any solution on the Net yet ?...
For information, I can make a bios dump if necessary.
Thanks a lot ans best regards

Add motherboard number, device serial number, and attach your bios dump - doesn't matter if it's corrupted (as in your case) or not. By doing this you increase the chances of getting quick and accurate help in solving the problem.

Thank you very much for the help. but it didn't work, I programmed it first, pure bios, it did the same thing as soon as I connected it flashes 3 times on. Then I programmed ec chip it8186vg and it did nothing. Return to the original ec and the ignition flashes 3 times again. I include the original ec to see if the problem is there

Thanks for your reply.

But the bios file is 16MB is it ok? Because I tried to use the one download from Lenovo ($0AR0400.FL1) before but when I tried to flash got error exceed chip size something like that.
