thinkpad edge s230u twist can't access bios by F1,bios recovery

When I tried to update win8.1 updates KB3000850, it failed via auto-update or installation. Follow the Microsoft guide to restart laptop into safe mode, installation failed also. Then I chose safe mode with minimum way to restart laptop. Then laptop halted down at Lenovo logo.

At first, I thought bios is modified by windows8.1(x64) and it can't load any hard disk to boot. With a couple of days test, I found a way to flash BIOS at very beginning of laptop boot. BIOS can be updated. But there is still no startup option to set boot sequence. My laptop is still halted down at Lenovo logo, same as BIOS update. I can only access bios by keeping real clock error which I generated by clearing BIOS.
if no real clock error, i can't access bios. And f1 and f12 doesn't work. At the lonovo logo screen, Enter doesn't work also although it hints me to press Enter.

In my laptop bios, there is no startup option even I udate it.

can somebody help me on this? Lenovo service center just aksed me to change board.

Here I share the bios crisis recovery solution for s230u, may also for other models.

Laptop: ThinkPad edge s230u twist 3347-3QC
Bios: 1.67, UEFI.

OS:windows 8.1 x64

How to do BIOS crisi recovery:
1. Download bios(exe version) from Lenovo website
2. Run it, and release file. Uncheck the installation at last. Remember the release location. You can get the bios in .fl1 format, mine is in ..\gduj21us\GDETA9WW\
3. Rename it as BIOS.cap and copy it into a new formatted USB stick with FAT32 in root directory.
4. Shutdown Laptop and disconnect AC cord. Insert USB stick.
5. Hold Fn+R, plugging in AC power. And power-on.
6. USB stick is blinking, then you can release key. A short while, after a lenovo logo, flashing screen shows.
7. After flash, laptop will restart or shutdown.

In BIOS, it shows new version. If new bios is new one, flashing takes a longer time than a very short time for same version flashing.

I tried 1.02, it will try to read USB stick, then shutdown, restart, read again, laptop would be in this cycle. It's same when i changed one Bit by hex-editor of 1.69 version. I also try to use PhoenixTool 2.59 to rebuild BIOS after change one or two Bits of extracted roms. same status also, it took the changed bios as wrong input, enter the above cycle also.

I tried 1.53, it can show lenovo logo, and flashing screen, but it hints that BIOS should be qual or newer.

I still wait for some on guide. Thanks in advance.
