Thank you so much! I installed the new BIOS and it worked! It displayed an image via HDMI but not on the screen. Actually, it did, but the screen didn't light up.

Do you have an image when you shine a flashlight to the screen? That means "no backlight" fault, check the backlight fuse FG3301 first, open a new thread in troubleshooting laptops section if you need help https://www.badcaps.net/forum/troubl...mobile-devices
Schematics https://www.badcaps.net/forum/troubl...59#post1654359
Common fault if the screen is disconnected before disconnecting the battery; unplug battery, measure continiuty across the fuse FG3301, if blown, replace it, 3A 32V 0402 size fuseComment

Witam wszystkich, bardzo proszę o pomoc w rozwiązaniu problemu.
Laptop po włączeniu przycisku Power pozostaje ciemny, nic nie wyświetla, świeci cały czas przycisk. W momencie włączenia przycisku słychać na chwilę wentylator i cisza.
Odczytałem wsad układu GD25B127D bardzo proszę o weryfikację jego poprawności lub uszkodzenia.
Pozostałe układy: IT8227E-128
Płyta: GS454/GS554/GV450/GV550
Grafika zintegrowana.
Poza biosem nie mam się czego przyczepić.
Hello everyone, I'm asking for help with this problem.
After pressing the power button, the laptop remains dark, there's no display, and the button remains lit. When I press the button, I hear the fan briefly, then silence.
I've read the GD25B127D chip's datasheet, and I'd appreciate it if it's correct or faulty.
Other chips: IT8227E-128
Motherboard: GS454/GS554/GV450/GV550
Integrated graphics.
Aside from the BIOS, I have no complaints.
In English please...

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... -
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,...10-11-2024, 03:12 PM -
