OK, I have another build prepared for you and if this isn't working for you the maybe some other forum member will help you out.
If a build isn't working always write back the original to assure you didn't blow away a component or you don't pick up by mistake a component with the soldering iron...
Good Luck!Comment

Hi everyone, I have a Lenovo ideapad 3 15iau7 main board NM-E341 PC which showed no signs of life, I found the PC1502 and the PQ 5400 short circuited, replaced the faulty components and now the PC turns on, draws 600 but does not boot, black video, 3 LEDs on the keyboard are on. I checked the 2nd bios chip and the UB3 W25Q128 eeprom chip was unreadable, while I was able to read the UB2 W25R64 eeprom. I replaced the UB3 W25Q128 with a new one, I extracted the bios from the Lenovo site by putting the PC serial number PF4HXNHB, I extracted the 2 flashed files in the 2 eeproms but it continues to present the same problem.
+1.6V_VCCCORE gives only 0.8 volts
+1.5V_VCCGT absent 0 volts,
+1.8V_VCCIN_AUX is ok 1.8 volts
I tried other bios downloaded from the site but none of them work.
Any advice?
any help?
ThanksComment

The Serial number, SNID or Service Tag must be posted with all bios requests -> https://www.badcaps.net/forum/troubl...before-posting
Try the ram patcher script or search on google for the SPD removal tool -> https://www.badcaps.net/forum/troubl...20#post3232220

I flashed it, the LED lights up, the fans don't spin, the display doesn't light up, and I can see the BIOS reading from the chips on the oscilloscope. Most likely, there are still problems with the motherboard, I'll check the voltages more thoroughly,
Thank you very much!Comment

Здравствуйте! У меня проблема такая же как у ministeri из поста 68. Имею Lenovo ideapad 3 15iau7 NM-E341, при подаче питания происходит самовключение, потребление около 660 mA, инициализации нет, 3 светодиода на клавиатуре включены, а светодиод кнопки включения начинает сразу мигать, кулер крутит секунд 5 и останавливается. Долгое удержание кнопки питания выключает ноутбук. Пробовал шить Bios и EC чистым с сайта и другим дампом, ноутбук ведёт себя так же.
Замеры питаний в норме, кроме: +1,6V_VCCCORE которое 0,82 V и +1,5V_VCCGT которое 0 V
Hello! I have the same problem as ministeri from post 68. I have a Lenovo ideapad 3 15iau7 NM-E341, when power is applied it turns on automatically, consumption is about 660 mA, there is no initialization, 3 LEDs on the keyboard are on, and the power button LED starts blinking immediately, the cooler spins for 5 seconds and stops.
Long-pressing the power button turns off the laptop. I tried to flash Bios and EC clean from the site and another dump, the laptop behaves the same.
Power measurements are normal, except for: +1.6V_VCCCORE which is 0.82 V and +1.5V_VCCGT which is 0 VComment

Привет, ЕвГений, не могли бы вы попробовать эти файлы Bios и EC. Надежда может дать вам свет [/ЦИТАТА]
Я попробовал эти файлы, без изменений. Вот мой родной дамп
I tried these files, no change. Here is my original dumpComment

Hi, I also tried the Bios posted by Hairulole in post 75 but it doesn't work, same problem: 3 keyboard LEDs on, fan running for a few seconds and 600 Ma of absorption. The serial number of my PC (PF4HXNHB). A huge thank you to anyone who can help usComment

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... -
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
- External display (HDMI) shows

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 -
