Здравствуйте. У меня Lenovo Legion Y9000P 2021 (Legion 5 Pro 16ITH6H). Аппарат из китая. Со слов китайца инженерный образец. Текущая версия биос H1CN10WW. На офф. сайте Леново скачал версию H1CN58WW. При попытке обновиться выдает ошибку. Возможно ли обновить мой образец ноутбука. Скиньте пожалуйста рабочий вариант биос для моего ноутбука если таковой сушествует. Серийный номер PF2JHCJE
Hello. I have Lenovo Legion Y9000P 2021 (Legion 5 Pro 16ITH6H). The device is from China. According to the Chinese, it is an engineering sample. The current BIOS version is H1CN10WW.

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight

Hello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.
I decided to try flashing a new BIOS, but since I didn’t want to desolder... -
