It seems my suggestion to try QIW4 was wrong, so I am sorry if I wasted your time. But you still have problems.
GET LENOVO TO FIX IT
If you're still under warranty just send it back to Lenovo. They will replace your motherboard for free. Don't tell them that you flashed the BIOS. "It just stopped working, I don't know why!" But maybe the warranty has expired, so this could be expensive.
This will save you psychological torture. Or ........
YOU STILL WANT TO FIX IT YOURSELF?
OK. I will try to help.
If you did not make a backup of your BIOS then where did you get the BIOS that you tried to restore with?
What was your BIOS version before you tried to flash it? Was it v8.01?
Or was it something different, perhaps v2.07?
Lenovo have never put the official version of the v8.01 bios online.
Seriously, there isn't a single post in this thread where someone reports successfully restoring the BIOS using the fn+b method. Very frustrating!
THE FN+B method
I'll just tell you what else I read regarding this method, in case you want to try these things (BTW, the original explanation is here)
If you download a default stock BIOS from Lenovo, it will probably be inside an EXE file, and you can extract it from the EXE using winrar. But make sure you know what rom version is inside the EXE file and if you can't confirm it's the one for your machine, then don't use it.
Then you put the rom file into Andy's tool (download here) and it will examine the file and tell you in a pop-up window, what to rename the file when you use it to flash the rom (but I seriously doubt that it will be a name that you have not tried and I am not trying to torture you!)
The online EXE file that most people link to is here, it's called 5dcn40ww.exe. It contains a rom called "QIWY3207.ROM". But I don't know what version of the BIOS this rom file is, I think it is BIOS version v2.07, definitely NOT v8.01.
If you try the fn+b method then you must put the USB stick in the USB 2.0 port which is the one next to the power input socket, on the right hand side at the back.
You should press the power button after you have removed the battery and keep the power button pressed in for about 30 seconds (release it before you put the usb stick in)
Keep pressing fn+b until there is a beep or until the light appears on the USB stick (use a USB stick that has an LED for read/write) and that you might have to wait 2 minutes for that to happen.
If the fn+b process IS working, "you can expect the fan to speed up and after a short while, and then the notebook starts to beep periodically. After 2, 3 minutes the laptop should shutdown itself. Disconnect the usb drive and restart the laptop. The bios should be restored."
BIOS BACKUP FILES THAT USERS HAVE PUT ONLINE (not uploaded by Lenovo, not stock ROMs)
1- BIOS v8.01 (full name - 5DCN90WW(V8.01) – made with FTP64 program - the link came from this page
which is forums.digitalmy.net/threads/7033-Insyde-bios-mod-requests/threads/7033-Insyde-bios-mod-requests/page1446
2 - BIOS v 8.02 (full name - 5DCN91WW(V8.02) – newer than v8.01. Link from here
*I do not know what the dangers are of using other people's backups to restore your own BIOS, I disclaim any responsibility.
BTW-You do not get the names of these user-backup ROMs when you load them into Andy’s Tool
RESTORE BIOS TO DEFAULT SETTINGS BEFORE ATTEMPTING TO RECOVER THE BIOS?
There are some suggestions here for restoring the BIOS to its default settings (usually when people have flashed the BIOS successfully but then changed BIOS settings and fucked up the machine that way.
1 - POWER BUTTON METHOD
Unplug the DC power and take out the battery. Then press and hold the power button down for 30 seconds. Some people suggest leaving the battery out for 30 minutes and only then plugging everything back in.
2 - FN KEY METHOD
Remove ALL power sources from the laptop, including battery.
Hold the POWER button for at least 30 seconds
Release the power button and then connect the AC ADAPTER , hold down the FN KEY while pressing the power button momentarily to turn the system on, but keep the FN KEY pressed until the computer self-reboots a second time, by this time the computer will start again and you will hopefully see the Lenovo logo on screen.
3- BLIND RESET METHOD (when screen is black/blank)
Press and hold F2, turn on the laptop and keep F2 pressed down for at least 45 seconds. If you are lucky, you are in the BIOS menu, though you can't see it. Then press press left arrow key once, then press down arrow 4 times, and finish by pressing "enter" 4 times. If it doesn't shut down or reboot, shut it down manually.
4 - REMOVE/RESEAT CMOS BATTERY (everyone tries to avoid surgery!)
Getting to the cmos battery requires disassembling the laptop. The CMOS battery is under the trackpad (mousepad). You can see the CMOS battery in this picture, in the bottom left corner.
You'll have to remove the top of the laptop to get to it (if you are lucky then maybe all you need to remove is the keyboard). There's a video on opening up the laptop
and he takes the top off in this video.The repair manual in English is here, it's clear, if you understand the English!
DC power and battery will be removed to disassemble the laptop, so just remove/disconnect the CMOS battery for 10 minutes then put the laptop back together. The battery removal may be like this one here.
Flash BIOS again using a bootable USB stick
Even if you can't see anything on the screen, your laptop may still be able to boot from a USB stick.
You'll need a ROM to try (not the one that made your computer die!). Hopefully a stock rom from Lenovo, that is the right one for your machine (though at this stage you may be desperate enough to try anything!)
Use the windows "HP USB Disk Storage Format Tool" to make a USB stick bootable (how to do this) and add a DOS operating system (you'll need DOS files in a folder for this HP utility to be directed to). Then add the fpt dos program files to the USB stick and the prr2.exe files aswell. On the USB, replace the "fparts.txt" file that came with the fpt dos program with the same file in the error-104-fix, available here
Put a copy of the ROM file on the USB stick and rename it restore.bin
Turn on the laptop with the USB stick in. It may boot into the OS on the USB, you should see the light in the USB flickering if it is working (but try the next steps even if there is no light)
About a minute after turning on the laptop, type prr2 and press enter, then type fpt -f restore.bin -bios and press enter.
If it is writing the BIOS then it may switch off by itself, but turn it off after 2 minutes anyway. You may be lucky!
I was wondering if it might be possible to use Lenovo's One Key Recovery button to restore the BIOS?
This is the small button next to the Power button.
If your windows was pre-installed then your OS setup files are kept on a hidden "recovery" partition on the hdd. If you press the Recovery button to start the laptop, instead of the power button, it will start to reinstall the OS and IT WILL WIPE THE C: DRIVE in the process, so you will lose all your personal data and installed programs.
But if there is nothing on the C: drive that is important and you don't mind over writing the data, then you might be able to restore the BIOS by pressing the Recovery button.
It's a long shot, just an idea.
Perhaps it's possible to switch off the machine before the recovery program actually writes anything to the hdd or changes your boot sequence, and that way you can keep your current windows installation?
