Lenovo flex 5-14alc05

[Simon Hofmann]

Hey guys, im pretty new to this topic so i need a lot of help. My Lenovo IdeaPad Flex 5 14ALC05 turned into sleep mode and the next morning only the ESC and Caps are lighting up and i have black screen. I can change the Keyboard Backlight and the Fan is running. I read some of this forum and tried it on my own, but im just too clueless. I bought a CH341A and read the current BIOS, but im not even sure if what i see in there makes any sense or is the Problem. Then i wanted to get a good File of Lenovo Support but didnt found a .bin there. I would appreciate any kind of help.

I am writing again but my problem is solved. Thank you. I downloaded the bios file in this post and learned the location of the serial numbers from another site. change and the result is positive.

Explanation 1: The serial number is located in two different locations (addresses 0x5EA080 and 0x5EA150).

The Windows key is located at 0x61709C.

I extracted it with 7zip but the size is not full. I can't do it. And when I run it, it is not in temp.

Hi. First thank you one more time for yesterday. I am sorry that I am writing here I couldnt find the right post. I told my friend today how you helped me with the BIOS and he sad that he also has a laptop with same symptoms like my had. He has Yoga 9 14IAP7 and I found 4 BIOS chips 3 from winbond and one giga device. I only managed to extract bios data from gigadevice chip. I tried guides that you sent me here yesterday but I guess I am not that good yet 😔 Can you please help me with this file as well. Thanks in advance.

I don`t know what to recommend, depends on your budget. Try this bios, it has your DMI included from post 203. I don`t know which post shiyab replied to but the serial number is different, and he did not add any DMI to the bios. Try again with the clip. keep it steady

It did not work and I'm getting the same probably corrupted bios dump from the chip. I ordered a new chip and I'll try to replace it and dump the bios you provided. Thank you for the dump!

I was planning on ordering a proper heat gun for de-soldering, do you know good heat guns to purchase?

What sort of heat gun do you have, if it`s a proper temperature controlled hot air station then sure. If it`s one of those paint stripper 1000°F ones you will likely cause damage to the chip and board.

I'm using both! Should I pull out the heat gun and do some surgery to remove the BIOS chip?

It`s corrupt. Are you using a clip, are you using a 1.8V adapter

It didn't work :/ here's a dump of what I'm reading from the BIOS right now. I really appreciate the help, thank you!
