B5400 failed BIOS update

2014-11-16, 13:37 PM
I tried to install the BIOS update from the official Lenovo site but it failed and after rebooting I can't access neither BIOS nor Windows.

Now I tried to recover it on my own using WinCrisis' recovery tool because as far as I know it is a phoenix BIOS. I failed to locate any .wph file or .ROM so I tried using the .fl1 file without decompressing it. I then prepared my USB drive but when I plug it into my PC and try to get into the BIOS recovery there is no signal that it is working like USB led blinking because it is being used. I tried pressing Fn + R/F/B and Win + B and nothing of those seemed to work.

Then I disconnected the BIOS battery because I read that it resets the BIOS. This wasn't the case, my screen still stayed black. I also read something about a jumper to reset it but I can't find anything that looks even remotely like this thing.

Now I am at my wit's end and I don't know what to do anymore. It is not issue with the screen cable, I'm 90% sure because it worked before and only stopped working after the BIOS update failed.

Either I used the wrong BIOS file or the wrong hotkey to get the BIOS recovery started. If anyone can fix this, please help me. Thanks in advance.

Just posted the same story. Totally the same, except the fact that I have M5400 model.

I've seen the date of your post and I suppose I have to wait... probably forever to get a reply from support.

If you have a fix, please share it with me. I have tried already all I could...

The support wasn't really helping. The couldn't tell me a fix here or when I talked to them on the phone. I just had to send it in to get it repaired. They said they don't have a replacement in stock so they refunded me my money.
