Hello, I wanted to update my laptop's BIOS from h1et40ww to h9et92ww. The website says I need to install h9et75ww first, so I tried installing that version first, but the installation failed and when I press the power button, the laptop momentarily turns on and off (the power light immediately flashes). I tried the crisis files with Fn+R but they didn't work (it works for about 30 seconds with Fn+R but nothing displays on the screen). How can I get a BIOS update file that I can use with Fn+R? Maybe I'm naming the files I put on the USB drive incorrectly. The ones I've tried are bios.bin, bios.cap,...

The laptop was working fine, the only problem was that when I turned it on, the screen was hard to turn on, it would wait for about 30-40 seconds before an image appeared on the screen.

Hi, my laptop suddenly shut down while it was running. When I try to turn it back on, the screen stays black and it emits a melodic beep.

I used Lenovo's SmartBeep decoder and it returned error 0284:


I then tried to enter crisis BIOS recovery mode by pressing Fn + R at boot. The melodic error code changes, but nothing else happens regardless of whether a USB is inserted. I receive another...

Hi everyone.

I have an engineering sample of a Lenovo ThinkPad X1 Carbon 11th Gen (TYPE 21HM-2FVT05, S/N PF-40G7CD) with an Intel Core i7 1360P (ES – Intel 0000). Since this is an engineering sample, the BIOS had a massive number of various settings. One day, I was experimenting with the BIOS settings and, after saving them, the laptop stopped booting and played a melody after pressing the power button, signaling error code 0002 (Internal bus error), just like in this post: https://www.badcaps.net/forum/troubl...shooting-lapto...
