    Lenovo L340-15IRH Type 81LK Gaming/IdeaPad BIOS Problem

    Hello,

    3 weeks ago when I launched MEMU (android emulator for windows) it complained about virtualization is disabled and gave me bluescreen. I turned off the device and booted to bios from windows advanced startup. I changed a couple and settings and boom! black screen. Not the typical one, no backlight, windows doesnt start (no hdmi output etc), it just bricked. Didn't want to wait for lenovo so i gave it to a local shop. He said bios is corrupt and flashed a new one. After i got the device i found out that my second hdd is not detected. I thought it may be damaged and ordered new one ( This one )

    But it did not solve any problems. And i noticed wired network doesn't working, not detected.

    Today i discovered that there is a new bios update. Here are my bios photos and new bios screnshot:









    As you may see some bios info is missing, product name, serial number etc.

    Should I install new bios? Would it brick it again? Do you advise me to use bios modification tutorial in this thread -> https://www.badcaps.net/forum/showthread.php?t=98038 and flash it?

    If you want mainboard pictures i may take photos and submit

    thank you

    Main board FG541/FG741 NM-C361

    You need the original BIOS of the machine. You have to ask the repair shop to fix the BIOS properly or at the very least to provide the backup. Hopefully they didn't erase it…

        Flash the new bios, you will also be missing the same DMI information as the old one.

          Lenovo L340-15irh bios/ec

          Hello! I have a Lenovo l340-15irh laptop (fg541 / fg741 nm-c362 rev: 1.0), replaced the power jack. It turned out that there is a short circuit on the LDO3 line. I replaced the damaged it8586e with a clean one. I did bios backups. I turned on my laptop, the it8586e chip was overwritten. Power button flashes 6/7 times, loop, flashes again 6/7 times and turns off. When turned on, Power lights up briefly and then goes off. I think there is a problem with the bios and the EC. I tried other bios and ec but same symptoms.

          Could someone clean the ME region and make the ec file from the original bios?

          thx

                                          Lenovo IdeaPad 3 - Hard Disk not recognized in BIOS
                                          by mkdj
                                          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.

                                          Here the steps I have taken to fix the laptop:
                                          - downloaded latest BIOS from Lenovo Website...

                                          Lenovo IdeaPad XiaoXin Chao7000-15ARR – only motherboard available, need help reconstructing clean BIOS

                                          Hello everyone,

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

                                          Unfortunately I only have the bare motherboard (no original chassis, no sticker, no working system).
                                          The laptop came with black screen.

                                          What I have:
                                          - Original SPI dump read from the board (W25Q64DW 1.8V, 8MB)
                                          - Official Lenovo BIOS update (.CAP file)
                                          - Photos of the motherboard (front and back)
                                          - Board powers on, but with original dump it stays black screen

                                          What I tested:

                                          by jendkkd jeje
                                          So a couple of years ago i got a bios update through Lenovo Vantage, so i installed it and bricked my whole BIOS, so i couldn't fix it so i put that ideapad in a box, 3 years later i found that one PC and want to recover it to switch from a 2014 hp laptop to this one.

                                          I found a method to recover the BIOS of many lenovo laptops tha consists in pluging in a USB Flash with the BIOS files and power on the laptop with Fn + R keys pressed until fans go loud and start beeping loud, but nothing worked, so i think filename is wrong, i tried naming the bios file as 07WW.BIN, BIOS.BIN, BIOS.fd,...

                                          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.

                                          Summary of BIOS Whitelist Removal Problem


                                          Problem:
                                          I am attempting to remove the WWAN card whitelist from my Lenovo ThinkPad T560.
                                          Initial Findings:
                                          • My current BIOS version is N1KET58W (1.45).
                                          • I have a CH341A programmer and have successfully created two full backups of my BIOS.
                                          • I have the ability to use command-line tools on a Linux machine.
                                          Troubleshooting Steps & Conclusions:
                                          • I attempted to use several automated and manual patching methods on my N1KET58W (1.45) BIOS, including using hex strings. These attempts all failed.
                                          • I concluded that the
