Yoga 7 2-in-1 14AHP9 Bios Chip

01-25-2025, 06:39 AM

I have a locked Lenovo Yoga 7 14AHP9 Bios chip. I cannot connect to It with the CH341A clip that I have. It wont hold on/connect. Any Advice or tips on how I can program this thing with a new unlocked bios? I am not experienced with soldering/de-soldering and was told by allservice it doesn't need to be removed, but unfortunately I do not have a pc with a LPT port for their programmer.

Attaching Picture of said chip.

There are some adapters to connect to it, but it will be a delicate operation. The best is to remove it and then connect it to the programmer.

Sorry, but as you say you are inexperienced with soldering, trying to work with this may make things very worse .

Asus Chromebox CN62 - wrong chip put on BIOS reader

by BMCappelletti

Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)

He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...

Lenovo laptop does not turn on, what does this number mean in a BIOS chip?

by thxd43

Hello, first of all, excuse me, I am using the translator, English is not my native language.

I have a Lenovo ideapad 330S - 14IKB laptop.

The tablet did not recognize me when I connected it, so I checked the device manager and I realized that there were many with the exclamation mark, so one by one I began to update their drivers until the sign disappeared of admiration, I even updated the BIOS, and the laptop rebooted normally and worked, so far so good, but the tablet still did not recognize me, I read on the internet that it could be due to a...

M715q Desktop (ThinkCentre) - Type 10M3 - Request bios chip location and useable bios for use with CH341A Programmer.

by hotcrossedbuns999
My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.
1. I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
2. I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
3. I could only locate two chips that look like bios chips. Could someone verify this
