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 BIOS update, they recommended returning it to a previous version, but There were no previous versions on the official Lenovo website, so I searched the internet for a version for my older laptop model, I downloaded the file and proceeded to install it, the installation wizard asked me not to disconnect the laptop and well, I did not I unplugged it, after it turned off to reboot it never turned on again and remains that way to this day. Then I realized that the outlet where I connected the laptop was not working well, so I did the test by putting a phone on charge and I realized that it was charging but at times it stopped charging on its own and I had to disconnect it and reconnect it again for it to charge. I don't know if this could have been the cause of the failure on my laptop.
When I press the power button on my laptop, the screen turns on but in black color, and it does nothing else, it only shows black color, it does not show logos, no text, or anything, it only shows black color, and the fan works and spins It spins but doesn't do anything else.
Searching the internet I read that it could have been that the BIOS chip had suffered a defective programming and it could be reprogrammed with a device and solve the problem, I got down to work and downloaded the most updated BIOS file from the official page of lenovo and estraje the atchivo .bin, I also bought the CH341A programmer.
Looking at tutorials on the internet, I observed how they programmed with this device and it worked fine, but it gave me an error and it did not recognize my BIOS chip, again searching the internet, I came to the conclusion that the bios chip could have been physically damaged and I have to replace it Well, it turns out that the BIOS chip on my laptop is a winbond 25Q64JVSIQ 1735 model.
The problem is that I can't get exactly that BIOS chip, whenever I find it on the internet they are web pages that do not ship to my country Colombia, but I find BIOS chip models almost the same as if they ship to Colombia but the last ones differ four digits, for example I find this chip BIOS winbond 25Q64JVSIQ 1733.
Change 1735 to 1733, my question is, what does this number mean in a BIOS chip? Can I install winbond 25Q64JVSIQ 1733 instead of winbond 25Q64JVSIQ 1735 and would it work fine? or on the contrary, will my laptop continue to be damaged if I do this?
Another question I have is: Can I program the winbond 25Q64JVSIQ 1735 BIOS chip with the CH341A programmer or the winbond 25Q64JVSIQ 1733 chip? That is to say, the programming voltage works for me, I understand that sometimes it is 1.8v, other times it is 3.3v, but I don't know how to consult this information in the characteristics of the chip, I am new to this.
I wait fast answer.
