Hi guys, I need your help. After updating the BIOS directly from Lenovo tool, the laptop is not working anymore. It starts (led lighting, fan rolling) but has black screen even using an external monitor. As the only thing I've done was update the BIOS, I think the issue is there. I don't have a backup because I've used the Lenovo tool.
Laptop: Lenovo S145-15IIL
Board: GS44D/GS54D NM-C711 Rev 1.0
S/N: PF1BFQZM

Can anybody help me?

Thanks

Yes, I've seen it but I don't have a backup. I've tried to save the current corrupted bios and for me it's just full of 0s (see attachment) and therefore I don't the other values to load. It's the first time I try to do these kind of things... 😅

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

At the end, I've managed to unsolder the chip and solder it back after have programmed it.
The laptop is now working again but I've an issue: the additional memory is not working. It's not a problem of the memory itself because I've also tried to use another working one and the issue still persiste. Could it be possible that the new bios is not supporting it?
