Trying to fix a Lenovo 1-14ast-05 which had a BIOS update interrupted and now powers on with flashing power button and solid caps lock light.
Downloaded the BIOS update file from Lenovo here:
https://download.lenovo.com/consumer...s/cwcn23ww.exe
Then I followed the steps here on how to extract the CAP file using UNIEXTRACT
https://www.badcaps.net/forum/showth...light=tdk+bios
Although the directions mention needing to extract twice to get the cap file, but UNIEXTRACT extracted WinFlash and CAP file in one go. I then edited the CAP file in HxD to extract what I thought was the correct 8192KB file and saved it.
Using CH341A programmer the standard software doesn't appear to support this BIOS model 25U6473F so I downloaded AsProgrammer 1.4.1 from here:
https://github.com/nofeletru/UsbAsp-flash/releases/
Read and dumped the BIOS chip with AsProgrammer (attached to this post as Original-BIOS-dump.zip). Then erased chip and flashed the BIN created earlier in HxD (attached here as Extracted-BIOS.zip) but system still won't post.
Did I miss a step somewhere?
Thanks.
