Hello Forum,
Months ago the motherboard of one my laptops (ASUS F555L) got broken (I was almost 100% sure about that after t-shooting but I took the laptop to an authorized repair shop and it was confirmed). The repair shop offered to replace the board for ~900 BGN (around 500$) which was ridiculous given the fact that I bought the laptop (brand new) for 700 BGN (around 390$). After some searching I found a replacement board with even better processor for just 140$.
After months of waiting I finally got the board, replaced it and the laptop was back to life (almost). The only thing that wasn't working was the display, however I was able to use an external display without a problem. I figured that maybe this was some sort of driver issue so I started downloading new drivers for the new board (ASUS X555LD). Everything was fine until I've decided that upgrading the BIOS will be also a good idea....
At the moment the laptop will power UP and that's it - no Windows, no BIOS, no image - just a black screen (the same way like it used to be before replacing the board). I'm not even 100% sure if nothing happens or just the display is not working...
I was reading that there's a way to flash a new BIOS from a USB drive but I'm not sure if I'd be able to do this with this board. Furthermore I'm not even able to take out the CMOS battery from the motherboard because it doesn't have one. For the update I was using firmware and tools from the ASUS' website and before the restart of the machine everything was fine - I also received a message that the update was successful.
P.S. I'm aware that this ASUS series are quite crappy but my mom was using the machine in order to run very lite software products and it was doing the job just fine.
