========================
Detailed description:Hello All, I just updated BIOS (using an external USB drive) on my ZenBook UX305F with the BIOS I downloaded from Asus website (version UX305FA-AS.216). The BIOS update took the new version of the file and it seemed like everything was going well with the installation till the software installation went into a restart and the laptop never restarted. I tried hard reset (> 40 Seconds with both Battery and charger removed) and it looks like the BIOS upgrade bricked my laptop. There is battery light (on the side) when I connect the adapter and I don't see power button light coming up or the light bulb (LED) on the side come up either. Any help to recover and get back would be appreciated. Thanks, Sunny

octaviaThanks for everyone's help so far.. Here's what I have done so farHi
I would recommend that you should consider a clean install of your existing Windows 10. You can use below guide by Greg Carmack, MVP for this purpose. This is the best method to perform a clean install of Windows 10. (If you want to rescue your files, there is a section Rescue Files when Windows Won't Start)
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved

I disconnected the main battery cables by removing the connector from its socket. I located the CMOS battery for the BIOS and I disconnected it from the circuit by removing its connector for some time. Now, keeping the main battery disconnected, I put back the CMOS battery and plug in the adapter plug. Surprise, the notebook comes up. But, there is no light on the power button. There is light on the side though.
Now, if I put back the main battery and try to turn on the notebook, it doesn't come up with or without the adapter power. There is no light on the power button either. So, in summary the laptop only comes up when the CMOS battery connections are interrupted and reconnected along with the adapter being plugged in. When I put back the main battery after the notebook comes up, the notebook recognizes the battery and nothing bad happens... It looks like I have lost on/off control through the power button as well.
I have reset the windows with a clean install and downgraded the BIOS to 206 version ( I had 216 recently) and it doesn't seem to make any difference. All of this issues started with my touchpad being stuck, which prompted me to upgrade the BIOS and now I'm seeing a host of issues.. Sorry for the whole spiel.
I hope someone from Asus can help me here.
