Thinkpad L480 Bios repair

[figuevin]

Hello everyone,

Cordial greetings.

I have a doubt, in the lenovo L480, there are two bios chips that are in U0901 and u4502. Both are reprogrammed or only the U0901? What function has the U4502?

Thank you very much for your help

Hello Markus 1741!
Thank you for your help.
Unfortunately, it doesn't work. The truth is that bitlocker is on.

Thanks

you have clean_ME bios - try it 1st, if doesn't work try r0quj11w.bin, is extracted from bios update, same version as yours but you'll have to write your DMI with LMU.

Hi Volinakis

Thank you for the files. Unfortunately it is still the same with both files. When I plug in the charger the charging indicator lights up orange but then after a couple of seconds it turns off and then restart charging. I can see on the AMP meter, that it takes 20V and up to 2 A but cycles/loops/restarts. Nothing on the screen. Keyboard still fading and ESC and Caps lock lights up. Any suggestions?

Sorry if I have not made myself clear. My reply was in terms of another/different bios file that could help get it work. Could it be the other bios? under 1mb? Not a specific hardware question - but I'll move it if you want me too.

Hello
I received a black screen. The bin file I received works. It only accepts bitlocker images. Unfortunately, I don't have a Microsoft account. I don't have the option to restore the laptop. Thank you in advance for your help.

made a windows usb key and reinstalled it.
bitlocker is not a problem unless you want to recover information on the disk
