Hello,
TLDR: I need to flash the BIOS and EC on this laptop. There are 3 files. Two BIOS files that I know how and where to flash. But I don't know what to do with the 128kb EC BIN.
I have an issue with this laptop that I have never experienced before with any other laptop.
It was working OK on Windows 8, which is the OS that it came with.
I went to upgrade to Windows 10, and immediately upon reboot the screen went black, but the laptop would still power on.
I tried all the normal fixes like pulling the battery and holding the button. Known good RAM in each slot. External monitor, and a few other things, but nothing worked. Every time you turn the laptop on, the fan spins and the power LED comes on, but the screen never turns on.
I thought maybe I was just really unlucky and I have a motherboard failure while installing Windows 10, but to my surprise, many other people on the internet have had the EXACT same issue. They had a working laptop, tried to upgrade to Win10 or tried to do an OS "reset" and afterwards their screen would never turn on again. I am not sure if I am allowed to link to other forums here, but I found at least 6 people with the same problem. One person it happened to on the same day he bought the laptop, after he tried to upgrade to Win 10. So, obviously, there is some major issue with these boards when you try to update the OS.
One person said he solved the problem by re flashing the EC so I want to try.
Here is where my inexperience shows...
If you look on VinaFix and even on BadCaps, someone has posted the BIOS and EC for this laptop. It comes in three files.
One of the files is U940_PSU6SE_UH4_25Q16CV.ROM. I assume this is to be flashed onto the IC labeled UH4. I already did this with my SPI programmer.
And another file called U940_PSU6SE_UH3_25Q32BV.ROM which I assume will go onto IC labeled UH3. I also already flashed this one too.
But what about the 128kb BIN for the EC? Is there a third IC somewhere that I need to flash with EC BIN?
If anyone could clarify how to "flash the EC" that would be great.
