Thank you for replying! I wasn’t sure if I’d receive any replies
So yes, there’s a recovery process called BIOS Crisis Recovery.
I currently do not have any Lenovo splash screen upon boot. Just a black screen that’s accompanied for the most part, with a blinking power button light which blinks I second intervals.
Upon power on, I don’t hear anything when my ear is pressed near by the touchpad… But after about approx 20 to seconds, the fan on the right does kick in at low speed and stays at that pace until I turn it off. By this point, I will hear a light hum which doesn’t change pitch, tone, intensity or volume. I’m guessing that it’s the fan. Also I can hear what I presume is the EC doing something because I’ll hear like a quick “click/pop” type sound maybe 1 or twice at most over the course of 10 to 15 minutes.
Also, I’m nearly 100% certain that when I first power it up, the back light for the keyboard will light up for about 2 or 3 seconds approx and then stop. Caps lock key doesn’t show any light, neither does numlock. Chat got says that’s to be expected.
The USB drive in currently trying out is a 4gb stick formated to FAT32/GPT and I’m put a file that I’ve extraxted from the official BIOS.exe file on the Lenovo website which is located under the BIOS/UEFI category.
On a different, working computer, I extracted a file called BIOS.fd by launching the official bios update program, I select “extract only” instead of install. Then, when I get that file which will be another .exe file,.I will then use 7zip, and click “extract here” . That will provide me with a folder and in that will have BIOS.fd.
Apparently the recovery process that I’m trying seems fairly consistent …other than experimenting with different variants for the file name label… Those variants have either come from some posts on this site, reddit, the Forums on the Lenovo site and Chat GPT. Same as well for the key combination to try. But the result from the laptop so far has remained the same. There is one new development I was told by a Lenovo rep when I called And she said to use the novo button and name the file BIOS.cap. no luck however. Chat GPT also said that .cap wouldn’t be for my board because it presumes its API based I think it said. ANI? Ami? I can confirm if needed.
I’ve seen that BIOS.fd needs to be relabeled as BHCrisis.bin. I’ve seen also BIOS.cap, BIOS.bin, and a few others. The key combos vary from Fn + r, Fn + B , Fn + Del, Fn plus S and V, and a few others.
I’ve been attempting this so far with holding the key combo, tapping the power button as I continue to hold the key combo for 30 seconds, but all that happens in the following 15 min is just as I explained above: keyboard light turns on for a few seconds, power button light blinks at 1 second intervals, fan starts low speed in under a minute or so. No beeps, no auto reset, no changes in blinking rate, no change in fan speed or hum. The USB Drive also just has a steady ready light whether the computer is on or off so long as it’s plugged in.
Ive used the UEFITool once now so far, and the .fd files I have been able to open up , when I take a picture of the information it displays, CHAT GPT verifies that it is good to use.
Is there any additional info or observations I can mention? Anything that you recognize right off the bat by chance?
I’m only getting by through chat gpt and Deep seek
