Re: Legion 5 15ARH05 bios
Ah thanks for that! I've managed to get the Serial number to show up in the BIOS.
Now the next problem, I don't seem to be able to access any Boot devices. I'm new to all this and I've been trying to find similar threads but no luck.
The laptop seems to take about 10 seconds from turning on to finally show the Legion logo and allow me to press F1 to enter the BIOS. Once in I can't get it to see the onboard hard drive or a USB drive with HirenComment

The problem is like this. I had problems with the EC, it was burned. I asked on the forum for a new EC bin and offered the original bios of the laptop. After I wrote the bin, the laptop started and displayed a message related to the charger, but the problem was that the laptop would not start unless I reset the bios. I saved the existing bios and put another one, and the laptop did not display an image. I put the last saved bios back but I still have no image.Comment

It is ok. Thanks. I don t have the original charger and the battery. If i want to start the laptop only with my power supply, the laptop not started. I must disconnect the bios battery, reset the bios and then the laptop starts. I have o battery from another lenovo laptop but it have 11.5v and my laptop need 16v. But if i put this battery, the laptop start when I press the power button and don’t need to reset the bios. I tried putting a 1.8k resistor between the ID pin and ground, but the laptop still won't turn on and doesn't recognize the charger.

Hi !
I tried to enter BIOS and it hangs (it shows a line on upper left corner) . When I push the BIOS button on the right side , I get a menu where I can select between normal startup , bios setup , boot menu and system recovery .
I choose bios setup and it hangs (the same if I push F2) .
What to verify ?
Thanks !07-21-2025, 08:45 AM -
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

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....
