Hey all, I have an Ideapad 3 15ITL6 in house and theres no backlight, I changed the LCD hopeing but same outcome. Ive run the board around my microscope a few times and cannot seem to find the backlight fuse if anyone knows its location or has a schematic for the NM-D472 REV:2.0

The easy way is to flash a different bios that already has DMI in it -

Hello,

I have a Lenovo IdeaPad 3-15ITL6, Serial Number: PF49R4JL, that shows 12 short beeps when powered on, which seems to be a BIOS problem.

After disassembling the motherboard, I noticed it has two BIOS chips:

• One XMC QH128AHIG (16MB)
• One GigaDevice GD25B64 (8MB)

I’m looking for the original BIOS dump files (BIN) for both chips, if available.
I can reprogram the chips manually with a CH341A or SOFI SP8.

Any help would be greatly appreciated!

Thanks in advance!...

I have laptop Lenovo IdeaPad 3 15ITL6 with Intel Core i3-1115G4. When I press the start button, LED light on the start button starts blinking 12 times, then stops and after some time starts blinking 12 times again. When it stops, all voltages are down.

The motherboard is HS460 HS560 HS760 NM-D471 Rev: 2.0
S/N: PF3Q0WTF

The motherboard is not mine, also there were corrosion on the board which I cleaned.

Methods of fixing like fully turning off the motherboard or starting only with adapter doesn't work. All testing were did only with adapter on.

Hello! My notebook has a blinking power light and no video, I believe its a Bios issue.
I need the bios for Lenovo IdeaPad 3 15ITL6 SN: PE0ACWX9.
I have downloaded the Bios file from the lenovo website, but after converting to .bin there is only one bios file with 25MB, and I need 2 bios files so I can write with my CH341A writer on both bios.
Thank you very much, I need it to work, If someone can help me fix I can donate....
