Hello guys, I need some advises.
I'm buying used Elitebook 840 G1 laptop with EC & Main BIOS chip in it. The EC is Winbond 25Q16BVSIG and the Main chip is Micron N25Q128A. My laptop randomly crashing with glitched screen and static sound, and then it won't turn on with 3x5 blinking capslock (which I know it's board failure).
Then I tried to reprogram these chips with different softwares. I'm using CH341A, default CH341A software for winbond and using asprogrammer for micron (since micron chip cannot be reprogrammed using default software). It's work and my laptop normal again.
The chips looks like ever been desoldered before. My first question is whether the laptop crashing because the bios chips are damaged?
If I want to replace the Main chip can I use Winbond 25Q128FVSG instead? (micron chip not available in my country).
I also attach a document found from internet, not sure if it helps. I don't really understand about technical thing so I need your help.
thank you
