Dear all,

I have recently fixed a Lenovo IdeaPad 3 15 ALC6 that was not booting due to a BIOS issue. After flashing the BIOS, the laptop boots up, but hard disk is not recognized in BIOS. Is says "Hard Disk : Not Installed". I have tried with 2 different drives (one that I know is working on another laptop) but I get the same result. I do not know if disks were recognized before I got the laptop and fix it, but I don't see any reason why not. I can boot on USB though.

Hello everyone,

I’m working on a Lenovo IdeaPad XiaoXin Chao7000-15ARR (Ryzen platform) and I need some help with BIOS reconstruction.

What I have:
- Original SPI dump read from the board (W25Q64DW 1.8V, 8MB)

Hello Hello,

I have been browsing the site and gotten so much useful info from here, including extremely helpful boardviews and several other very useful types of information. I am very grateful to this community, as I have actually eeked out a living from buying salvage PC's & Macbooks and repairing them. So, thank you all in advance!


I have searched and found some useful information regarding my issue, but my case is a bit different than the info I'm finding. But if anyone here can give me any useful advice, it would be highly appreciated.
